My Internship at Open Mainframe Project

By | Blog

Written by Vedarth Sharma, OMP intern

These past few weeks were full of excitement and learning for me. The goal of my project is to make docker images for s390x architecture in SUSE Linux Enterprise Server 15 and automate the scheduled build process for clefOS images. The first half of the project was to make the images. We initially planned to build the images for openSUSE, b. But openSUSE had not been kept current with s390x. That forced us to switch to SLES15 instead.

My first challenge was to build a base image of SLES15. The base image will then get used by all of the other images. This was a challenge for me as I had never built a base image before. To accomplish this, Neale, my mentor, provided me an instance of SLES15 linux guest. I accessed the vm and wrote a bash script that will create a chroot environment, add repos to it, install essential packages and finally make a tarball. This tarball will then get utilized by our Dockerfile which builds the base image using `FROM scratch`.

After achieving this goal, I moved on to building more images for SLES 15. Then came MEAN stack. The tech stack of Mongodb, Express, Angular and Nodejs is very popular and we wanted it to be a docker image for s390x base SLES15. But we couldn’t find any official mongodb package for SLES15. I tried using mongodb for SLES12, but it didn’t work as it was unable to find a package `libcrypto` even though it was installed. We finally decided that we will wait for an official release of mongodb for SLES15 before building an image for mongodb and mean stack.

The next phase of the project was building a system to automate the process of building the images so that the images can remain up to date. I achieved it by building a pipeline in Jenkins. The pipeline is scheduled to run once every month automatically every whenever a commit is made to the codebase or. The pipeline executes the appropriate commands to build all of the docker images. This feature allows us to evaluate if a change is breaking the image and pipeline is failing, thus adding CI/CD support to the repository. I am building a similar pipeline for all of the images of clefOS repository as well which will keep the images of clefOS up to date.

Building the pipeline was a challenging part in itself. Jenkinsfile can be used to run bash commands and if the Jenkins server has access to docker daemon building images is quite straightforward. But the problem is you cannot push those images. For that you will need to do docker login and provide credentials which is quite insecure. Here is where docker build plugin comes to the rescue. In a scripted Jenkinsfile this allows you to build a docker image by simply writing:-

app = docker.build“(repo/name”)

This allows us to use the app and push the images to dockerhub by utilizing the credentials plugin of jenkins. But this plugin has a major problem. It only works in the root directory Dockerfile. So when I had to implement a solution for this what I did was simply create an app for each of my docker image and then copy the dockerfile and dependency files to the root directory run docker.build command and move those files back and repeat the procedure for other files. This is the only working solution that I have found which builds  the docker images and allows us to push them too from Jenkins itself.

I must say this has been a very challenging as well as rewarding project. Each day, I learn something new and I master it once I implement it a bunch of times. By working on s390x architecture based VMs, I have learnt how does a s390x system works. I am looking forward to working and finishing this project successfully.

Zowe Jupyter App: A Big Hit at the Poughkeepsie zModernization Summit Event

By | Blog, Zowe

Guest blog from Daniel Jast – IBM Z Systems Technical Specialist

The Poughkeepsie Client Experience Center recently hosted the annual IBM Z Summit Program Technical training event titled, zModernization Summit Event. At the training event, we provided 20 of the new IBM Technical Sellers in Z with hands on training in some of the “modernizing” applications on Z. These technologies included CICS, DB2, z/OS Connect, z/OSMF Zowe, Spark, ICP, Docker and more. The week let participants take a cobol application running on z/OS, expose the applications services into APIs, and then create a containerized application with those APIs which was then deployed out to the IBM Cloud. The application that was being run was a stock trading application which allowed users to create an investment portfolio, add stocks to the portfolio, and so on. We then let users get a hands-on experience on the Zowe Desktop and CLI, seeing how easy and simple completing complex z/OS tasks can be for new users by utilizing Zowe.

On the Zowe Desktop, we had created an IFrame application that had the Jupyter Notebooks running right on the Zowe Desktop. Jupyter Notebooks are used to exploit Spark to analyze data sources of your choosing. We had the Jupyter Notebooks analyzing Investment portfolio data which the users had created unknowingly as they worked through the technical labs throughout the week of training.

Training participants thoroughly enjoyed the Zowe and Jupyter Notebook piece. After getting previous training on “green screen” interfaces to z/OS, the Zowe Desktop and Zowe CLI were very well received. The audience was majority straight out of college, matching the target audience for the Zowe platform. When participants were asked what their highlights and key takeaways from the week of training were, some mentioned Zowe explicitly:

 

“Being able to learn more about Zowe and more innovative technologies integrated with Z.”

 

“Highlight: Zowe presentation!”

 

“My favorite (presentation) was the Zowe presentation”

 

“I think I really enjoyed learning about Zowe, and the hands on lab are super helpful in understanding!”

 

If you are looking to add Jupyter Notebooks to your Zowe Desktop, you can follow the github documentation posted here: https://github.com/zowe/jupyter-app

 

You can also follow the custom documentation written by the Client Experience Center’s Alex Lieberman(Alex.Lieberman1@ibm.com) and Dan Jast here: https://ibm.box.com/s/wo583vfw4klc2jg7l0zxo0k55yvw681b

 

If you would like to go through most of the Zowe Hands on Lab which event participants went through, you can request a demo from the Client Experience Center Demo Portal located here:

 

 

NOTE: If you are not an IBMer, you will not be able to participate in this demonstration without your IBM representatives help. You can contact Dan Jast (daniel.jast@ibm.com) for further information.

Dalian University of Technology Expects to Deliver New Zowe Tools

By | Blog, Zowe

Guest blog from Kun LU, Ph.D., Associate Professor, Director of Innovation Practice Center, School of Software Technology – Dalian University of Technology – China

When it comes to the Best DevOps Open Source Project, do you think it has anything to do with the IBM mainframe? Well, it does.  Open Mainframe Project’s Zowe, the first open source project based on z/OS, was named as a one of the finalists for the “Best DevOps Open Source Project” category by Devops.com.  Zowe is an open source software framework that provides solutions that allow development and operations teams to securely, manage, control, script and develop on the Mainframe like any other cloud platform. Leveraging the Zowe framework, we (DLUT) plan to develop and contribute a few tools to Zowe to help developers be more efficient, productive and agile in their daily work on z/OS.

We will work closely with IBM CSL CICS team and expect to deliver the following tools as Zowe plugins for CICS customers, first for the China market, in 3Q/4Q this year.

CICS Statistics Visualizer plugin

In the past, CICS health status check needs to be done manually by CICS experts who have profound CICS skills and experience.  The workflow includes understanding the system design, configuring CICS statistics programs and collecting CICS statistics data from CICS sample region at service peak time by uploading statistics data and analyzing the data, and finally generating reports and diagrams.  With CICS Statistics Visualizer plugin on Zowe Web UI, all the work can be done automatically.  The plugin also supports statistics data comparison of a single region at different time intervals, which can largely simplify the work the customer used to do before to monitor and analyze the system, like CICS health status change after CICS upgrade or configuration change, the trend of system resource utilization over time etc.  Furthermore, key CICS health indicators can also be queried by a simple shell command line through Zowe Command Line Interface (CLI).

CICS Liberty Debugging Assistant plugin

In the past, the customer needs to collect and store a list of debugging information from different storages and locations to troubleshoot a CICS Liberty problem.  This includes CICS Job log from mainframe JES, JVM profile and Liberty configuration files, STDERR/STDOUT/JVMTRACE files and Liberty output files like messages.log, trace.log and ffdc from zFS, MVS system dump accompanying with JAVADUMP, SYSDUMP and CEEDUMP dumps depending on the problem.  In addition, CICS trace level needs to be configured and Interactive Problem Control System (IPCS) must be used to format the unformatted dumps.  With CICS Liberty Debugging Assistant plugin, all the debugging related configuration, debugging information collection and dump formatting can be done conveniently by one-click operation.

CICS Application CI/CD plugin

Nowadays, CI/CD is widely used in software development.  More and more customers have increased demand on the z/OS development CI/CD to modernize the mainframe development, integrate with the distributed platform development, and assist the full stack developer to work with the mainframe services.  Zowe acts a good platform to eliminate the operation gaps to enable the z/OS development CI/CD, which provides some plugins like CICS and DB2 plugins to help simplify the application development.  As Git is widely being used for the distributed development, to centralize the code management, Zowe plugins (or cli) can be built for mainframe DevOps, like:

  • Trigger the build automation and end to end test automation (e.g. online COBOL or batch COBOL)
  • Trigger the env update when there is a CICS or DB2 configuration update
  • Deploy update into the multiple environments

Expose z/OS Connect EE APIs in Zowe API Mediation Layer

By | Blog

This blog was written by Andrew Smithson, an active member of Open Mainframe Project’s Zowe community and technical lead for z?OS Connect Enterprise Edition. This blog originally ran on IBM Developer’s website and can be found here

One of the key features of Zowe version 1 is the API Mediation Layer which provides a single place where you can find all the APIs that are available on your mainframe and access them from a single well known HTTP endpoint. When you first install Zowe, you get the APIs for working with data sets, Jobs, z/OS MF and the API mediation layer itself. If you want to add your own APIs, such as the administration APIs for a z/OS Connect EE server, you can use Zowe to add an existing API without having to change anything in the server that provides the API.

The configuration file contains the information about the server that is displayed in the API Catalog as well as the URI the server is available on. This file is then placed in the config/local/api-defs directory inside the API mediation layer installation directory. The API can be made live by sending an HTTP POST request to the /discovery/api/v1/staticApi of the discovery service. If you use the httpie client, the following command can be used.

http POST https://<hostname>:<port>/discovery/api/v1/staticApi

To make it easier to get started a sample configuration file is available on GitHub. This file can be updated with your server-specific details and then installed into the API Mediation Layer to add your own z/OS Connect EE APIs.

BUPT Students join the Zowe Community with a specific project in mind

By | Blog

Written by Kuang Jian, Dean of School of Software Engineering, BUPT

This is a guest blog post by Kuang Jian, Dean of School of Software Engineering at the Beijing University of Posts and Telecommunications (BUPT), a university directly under the administration of the Ministry of Education (MoE) and co-built by the Ministry of Industry and Information Technology(MIIT) in China. It is a comprehensive university with information technology as its main feature, engineering and science as its main focus and a combination of engineering, management, humanities and sciences as its main pursuit, which becomes an important base for fostering high-tech talents.

This blog will provide an overview into how BUPT works with the IBM China University Program and how students were introduced to Open Mainframe Project’s Zowe, an open source software framework for the mainframe that strengthens integration with modern enterprise applications.

Dean Kuang, students & IBMers at the IBM China Systems Lab

BUPT established a partnership with IBM China’s University Program in1996 and has participated in several of the program’s initiatives. In fact, the team from the School of Software Engineering in BUPT won the second place award in the ICBC-IBM FIN-Tech Contest in 2018.

Through the FIN-Tech contest experience, we had some basic knowledge of IBM Z and learned the value it brings to the market. Unlike distributed platforms such as Linux, it’s not easy for students in a university to have hands-on experience on the mainframe. So when Open Mainframe Project’s Zowe was introduced to us, we found it very attractive and wanted to know more.

From initial research, we learned Zowe was released last August to break the silo and reduce the steep learning curve of IBM Z. The Zowe framework provides interoperability and using the latest web technologies among products and solutions from multiple vendors. It helps enable developers to use the familiar, industry-standard, open source tools to access mainframe resources and services. An innovative framework based on a modern technology stack, Zowe provides the perfect opportunity for students to become the next generation of mainframers.

In addition to learning more about Zowe, the IBM China Systems Lab invited us to visit the China Systems Center for a mainframe tour. It was an amazing experience that inspired our students to join the Zowe community.

IBM Z expert introducing IBM Z14 and Storage DS8000 to Dean Kuang & students

We are collaborating with IBM to develop a native Zowe application plugin with configurable page and widgets to view data provided by IBM Z automation and monitoring products. We recently kicked off this project with three postgraduate students, who have already been assigned to work together with IBM advisors. We believe our students can complete the project successfully with their passion and the support from IBM and Open Mainframe Project. We are also eager to extend our knowledge and skill to open source and IBM Z and contribute code back to the Zowe community. Stay tuned for more details and updates…

Help us improve the Zowe install experience!

By | Blog

Joe Winchester, Senior Technical Staff Member of IBM gives details on the feedback that was received during the recent “Play Forward” open call for The Open Mainframe Project’s Zowe framework. Joe also explains how the Zowe onboarding squad is looking to engage Zowe users with its “Componentize, Update, Package, Install, Distribute, Support” initiative to improve the Zowe installation process. 

As the Open Mainframe Project‘s Zowe project reached 1.0 back in February 2019, the projects’ focus has changed from getting the initial contributions integrated and working together into smoothing out the overall experience of using Zowe.  The Zowe onboarding squad held a “playforward” presentation and discussion on the current install and improvements on April 23rd and a recording with transcript is available at https://zoom.us/recording/share/Lf8BmxIvmpXjTwJNfqXvvB-_jgkEMEE3Id3G_VRkiT2wIumekTziMw.

Some of the feedback we got initially included:

  • New releases of Zowe are fresh installs that are unable to share configuration and customization of previous releases.
  • Configuration data is held in the same directory as the runtime.  In order to launch multiple Zowe instances on different ports or different configurations requires different full installs
  • The lack of an enterprise installer inhibits deployment into production without install history auditing, rollback, and other features that SMP/e provides.
  • There is no prescribed location that a single shared and managed Zowe release gets installed into an LPAR that can be shared by different tools wishing to extend that single base.  Without this there is the risk of a proliferation of Zowe instances on an LPAR. This widens the number of Zowe instances requiring maintenance and support as well as undermining the cross tool integration that is one of Zowe’s core goals.
  • Zowe brings up many address spaces for functions that not all customers wish to use.  Customers have asked for a more modular startup process as well as the ability to lifecycle address spaces independently similar to a micro-service runtime stack.
  • Customers want the choice to consume Zowe releases, including PTFs and APARs, from commercial companies who extend Zowe through the support channels of the commercial company they have a relationship or contract with, but without impacting the ability to blend the solutions from commercial companies across a shared core Zowe software stack.

The onboarding squad in the Zowe project, which is a sub-group within the Zowe project that focuses on helping those new to Zowe with getting it successfully installed, is looking to improve this. Under an effort called “Componentize, Update, Package, Installl, Distribute, Support”, the onboarding squad wants to engage anyone who has installed Zowe to contribute to making the install experience better. Specific ideas being discussed include:

  • Provide an SMP/e distribution with the ability for z/OS customers to consume base Zowe as well as apply PTFs and APARs.
  • Separate runtime from launchtime data, with configuration variables being specified in a PARMLIB member so that independent launches of Zowe can be run with isolated ports and dynamic environment data
  • Allow Zowe to be started in a more controlled way so that individual microservices can be independently started and stopped without bouncing the entire started task.
  • Allow Zowe’s core function to be extended with new API servers and desktop applications at launch time without the base Zowe file structure requiring modification

Being an open source project means everyone can contribute to Zowe’s success, and this is a great opportunity to get started. Even if you can’t make the call, join the #zowe-onboarding channel on Slack or submit issues to the Install GitHub Repo to also participate in this work.

Cheers !

I Am A Mainframer – Usman Haider

By | Blog, I Am A Mainframer

In today’s episode of the “I Am A Mainframer” podcast, Steven Dickens sits down with Usman Haider. Usman is a masters student at NUST University in Pakistan and an alumni of the Open Mainframe Project internship program.  Usman tells Steven about his experience in the program, his thoughts about the mainframe, and it’s future.

 

Steven Dickens: Hello, my name is Steven Dickens and you’ve tuned into the I Am A Mainframer podcast, brought to you by the Linux Foundation. We’re a collaborative project under the Linux Foundation focused on the mainframe platform. And I’m joined today by Osman Haider who’s one of our former interns and who’s also loved the experience so much the discipline for this year’s internship program. Usman’s a master student at Nest University in Pakistan. An end to end developer who’s got experience with several programming languages. I’m really excited to talk to us as men. Usman, welcome to the show.

Usman Haider: Thank you. It’s a pleasure to be here with you today.

Steven: Fantastic. Usman tell the listeners and me a little bit about yourself. Tell us a little bit about your background and what you’re doing out there in the community.

Usman: So I am basically an electrical engineer. I did my bachelor’s in 2011 and since then I’ve been developing software in different programming languages. I’m an electrical engineer, but my interest in software is growing because of the open source community. And I love to contribute to open source projects and technologies, and my main interests are Linux development open source software development packaging cloud technologies software development for embedded systems. Currently, I am working towards overdevelopment I am and I am really interested in that.

Steven: Oh, fantastic. So interesting background not been in the industry that long, which is always good to hear. Tell me a little bit about how you got interested in the mainframe.

Usman: So, I am basically using Linux for more than five years. Last year when I was looking for an open source project to work during the summer, I came across a blog post and there was a topic that was mentioning the Master the Mainframe contest. So, I read the read about that and I started using the Z/OS system. And then I got to learn about the mainframe systems. That’s how I got inserted in mainframe, it’s power, it brings to the table, and the security. That was really when I decided to join the mainframe community.

Steven: Tell me a little bit about how you found the Master the Mainframe contest what your perspective was getting onto the platform and how you really found that as an on-ramp into the technology.

Usman: So I really like the idea about the contest, because it gives you a hands-on experience. It gives you access to the platform in a way that you don’t get. You don’t get access to Z/OS or the mainframe. For example, Linux architecture or the x86 machines are everywhere, but the Z systems or the mainframe systems are very hard to find. You don’t have any online access to those systems. So for students, it is a very good opportunity to get hands-on with the mainframe architecture and the z/OS.

It also covered all the technologies. So, I really the mainframe and I recommended it to other students as well and I am planning to do this again next year.

Steven: Oh, fantastic. So, you’re looking to enter the competition again next year?

Usman: Yes. And I’m also telling other students to go look for the contest and get hands-on with the mainframe contest, because I came to know that this skill is valuable. You can get people that know c++, Python, & x86. But this skill, I find it rare. So that’s why I am telling my fellow students and my fellow colleagues as well to really get hands-on with this.

Steven: Fantastic. So, you were an alumni of the Open Mainframe Project internship program, which just I think closed the applications for 2019. Could you give us a perspective of how you found that program what you were working on, and what your project was like?

Usman: So, I like the whole process of that internship program right from the student application to selection and to the completion of the internship program. The application process is very easy and consisted of answering a few questions only. You just have to give a few details about the project you are proposing. So, it’s not very hard for a student to apply. It’s not very time-consuming. So, it’s very easy for the students to apply and also there are a lot of good projects for students to choose from. There was information about the mentors, so they can always contact their mentors and see if a project fits their skill. So, my past experiences are very good.

I really like the idea of the kickoff call where all the selected students interact with each other. They tell each other about their skills and what projects they will work on. So, everyone knows who will be working on which project which is very good.

Steven: So I know to see it in the notes that was shared before us joining the podcast together that you did some really cool projects in your internship. Could you maybe share what you were doing with some of the listeners, so they can get an awareness of some of the projects that you were involved in?

Usman: So I selected the project that was titled “Increase the number of s390x packages in SUSE Package Hub Project”.  Although I had development and very basic software packaging experience, I never used something like Open Build Service. Open Build Service is a platform that allows you to package your software for different architectures and different distributions. So, a large number of developers are using OBS for packaging and many companies are also making use of it. So obviously it is a very active IRC channel and community, and they collaborate very well. So, I saw this as an opportunity to learn from and interact with experienced individuals and professionals.

So, during the internship, I worked on packaging the open source software for the s390x architecture. The main idea was to select different software packages like Zabbix, Icinga and Cacti that are monitoring packages, and to build and test those packages for S390X architectures For that testing, I got online access to the S390C machine using the IBM community cloud. I built all the software and then I deployed the software on the s390X. Then I tested the software, removed any bugs or reported any potential bugs to the community of mainframers.

There are a lot of open source packages available for Linux and what we were targeting in that project was to pull those packages to s390x as much as we could. So we were four students that were working on that project and we have all contributed a large number of packages. People can use those packages on S390 X machines. All those packages are available now on OBS and anyone can use them.

Steven: Fantastic. So it sounds like you had a packed few months. What were the biggest challenges that you faced and kind how did you overcome them?

Usman: The biggest challenge as an intern was to get started. There were a lot of projects and the biggest challenge was selecting the right project. But after that, there was a great mentorship from my mentor. He worked at SUSE as an engineer and he really helped us a lot. Everything worked as planned. So, there were no problems during the internship. So, the only challenge I think, was the project selection, because there were so many group projects and good mentors.

Steven: Okay. So, I noticed here in some of the notes that you’ve started to get involved in the Zowe community and that you’ve started to contribute and engaged there. How’s that been as a new platform to really get involved with? Obviously, it looks like you’ve done some good work in the Linux space. How are you finding that sort of front end to the z/OS environment, IE: Zowe?

Usman: So after I went through the Master the Mainframe contest, the feed it gives you is not very user friendly. It’s a black screen and you get to use a keyboard, and you navigate from using the keyboard. But after getting to know about Zowe in the last open source conference in Anambra, IBM introduced to Zowe. I really like the interface.

The reason why I’m so excited is that it is going to change the feel of the mainframe. I see this could be a big shift. It can attract more users and more customers. The purpose of Zowe I think is to make the platform more accessible. But in the meantime, we should not compromise on the scalability and security or any other useful feature that the platform is currently providing.

So, I think Zowe will bring in contribution from the large open source community because it’s an open source project. All of the open source developers can contribute and there is access to the Zowe machine. I think this can lead to potentially increase the number of consumers as well. So that’s why I’m really interested. We can make a big shift in the mainframe.

Steven: That’s an interesting perspective I think even with your insight, you’re spot on with where the community sees in that platform and the impact it’s going to have on both the existing mainframe clients but also bring in new clients into the platform.

So one of the questions I always ask my guests on the show is, where do you see the platform in two to three years time? How do you see some of the shifts we’re seeing in the mainframe space?

Usman: The mainframe in two or three years will be about adding security, the Internet of Things. The machine learning internet of things. Everything is connected, so that’s security’s main concern.

With the IoT and machine learning coming, you need a computational power as well. So, the mainframe is providing you both the computational power and security. The two main technologies you need in two to three years. I have seen technologies at the open source summit, the machine learning things on the IBM platforms, the speech to text things and the image recognition things on the IBM mainframe platforms. So I really see mainframe growing in these two fields. So I really see a big boost or increase in two, three years.

Steven: Yeah, we tend to see the same thread. I mean, it’s interesting seeing have clients are picking up on that security thread. I was reading an interesting piece that says your organization is either a data securer or a data abuser. I think a lot of people are going to see themselves on either side of that. People are going to choose who they place their business with depending on whether people are a data securer or an abuser. I think obviously we see the mainframe as a platform to enable people to secure their data provide that trust that clients.

So, as we start to wrap up. Is there anything else you want to share with the group before we bring this to a close? Are there any other parting comments?

Usman: One thing I want to mention is that there is not so much awareness in students and universities about the mainframe. Maybe I am wrong, but that that is what I think. When I attended the conference last year, I met people from different universities. There were people from 80 countries at the last Open Source Summit and I discussed mainframes with them, and there were I think only 10% of people who really knew about the mainframe. So, I wanted to highlight this point that if there could be a promotional campaign or some awareness. The community is already doing great. They are very welcoming to new people, but maybe if something can be improved, about the awareness of the mainframe and the access to the mainframe can be useful for the mainframe and the community as well.

Steven: You’re taking a part in that promotion today by spending some time with us on the Open Mainframe Project podcast. So, thank you for helping us get the message out Usman. It’s been great to talk to you. Thank you very much for your time today.

Usman: Thank you so much. Thank you for giving me your time and for giving me the opportunity to talk about the mainframe.

Steven: So thank you for listening. My name is Steven Dickens. I’ve been your host today. I’ve been joined by Usman Haider who’s one of the great community members impacting how this platform is perceived out there in the academic community and in the community as a whole. Hopefully, we’re going to be seeing a lot more advertisement as he continues to expand these efforts. Please subscribe to this podcast for future episodes. And with that, I’ll bring today’s episode to a close. Thank you for joining us on The Open mainframe project. I’m a mainframe or podcast.

Hey Raleigh! Join the new Mainframe Meetup Group!

Hello Raleigh and the rest of the world! We are excited to announce the official launch of ‘The Raleigh Mainframe Meetup Group‘. We created the Raleigh Mainframe Meetup group for a couple of reasons:

  1. The mainframe has been and continues to be, the host for the majority of mission-critical applications in Financial Services, Healthcare, Government, Education, etc.
  2. There is a demand in the Raleigh community for education and access to mainframe platforms and mainframe development tools.

We will be hosting and organizing three mainframe meetups for 2019 in the Raleigh area that will showcase the value of the mainframe from a technical and business perspective. We will focus on the following industries:

  1. Education & Academia – Bring awareness to the open mainframe project and help future developers build skills utilizing the tools available with the open mainframe project.
  2. Healthcare, Biotech, Life Sciences – How healthcare, life sciences, biotech are using cognitive technologies available on the mainframe to advance research and improve care.
  3. Financial Services/Fintech – How fintech is leveraging the mainframe with technologies like blockchain and adding digital services to existing core banking systems that are run on the mainframe.

Each meetup will include industry experts as well as a hands-on workshop. 

To stay keep up to date on the meetup group, join the group for details – https://www.meetup.com/Raleigh-Mainframe-Meetup/ and stay tuned at @OpenMFProject for more!
