3 What is it about? OBILE INSURANCE Mobile Insurance need to react to new German Law that wants to hold all health related records digitalized. Therefore the team of Mobile Insureance best people build a startup alike force that want to modernize the systems that interact with the health systems and also provide a new frontend for insurance agents as well as end users.

4 What is it about? In 2020 every citizen has a digital health record that is started with your birth or for already living people started from 2020 onwards. As technology a Blockchain in a federal cloud is used that can be accessed by all relevant parties, allowing them to add records and view them as to their access allowance. Every health insurance company has to manage healthcare related expenses and healthcare contracts in conjunction with this Blockchain as well as hospitals, doctors and pharmacies can use the data in the blockchain to get permissions for procedures or check previous issues. That reduces fraud and provides better insight for the citizens as well as for all participants (doctors especially). In our demo we are a healthcare insurance company who is dedicated to mainframe z/os. We want to connect our CICS-based core application with the federal Blockchain cloud and we want to build a new app in IBM Bluemix to enhance our service for our partners and customers. As we are an agile development shop, our developers can automatically provision the neccessary development and test environments on z/os with a click of a button and start to develop the new solution in parallel to our existing one. With the help of IBM AD we can scan our existing CICS application to quickly find all relevant positions in our code that need to be enhanced. The new function is created in CICS Liberty Profile other parts of the existing COBOL functionality is externalized via zos Connect EE, tested and rolled out via IBM UrbanCode Deploy. All the code (JAVA and COBOL) is stored in RTC together with the management of the development team. The components in IBM Bluemix can securely connect to our Mainframe via Bluemix Secure Gateway and can be developed in parallel. So this new challange could be quickly solved by our Team in very limited time and the quality is far better than it used to be in 2016 because all the best technology for the job was available by a single click.

8 Meet the Mainframe Team Mainframe Marcel Specialist for zos and CICS Marcel is highly specialist in system programming and able to perform nearly all tasks with a zos System, he simply has a JOB/REXX for everything. Transaction Tobias Specialist for CICS and DB2 Tobias is highly specialist in system programming and able to administrate DB2 and CICS. He also has plenty of experience in designing CICS applications and tries to stay current with technology. This modern world has no understanding of what it means to have production workload and all this click stuff is leading to chaos and will never work. We on Mainframes know best but are not asked. Everyone wants to have everything all the time and these guys are not willing to wait a few weeks till one have time to properly provision what they need.

9 Meet the Technology Architects Blockchain (Nor)Bert Architect and Innovator Norbert is an experienced Architect who has seen a lot of technologies coming and also going. His main topic these days are integration systems and the blockchain technology. Cognitive (C)Khadija Power Analytics Architect Khadija is experienced in Analytical processes and worked with many systems already. One of the main issues she has, is the actuality of data and the missing real time access. Modern technologies are key for the challenges of the todays world. Mainframes often still use technologies that are not ready for these new tasks. I want to analyze a lot of data in a quick way. Therefore it is the best way to offload all the data to a distributed platform and analyze it there.

10 Meet the Development Support Team DevOps Dennis DevOps Evangelist and Method Expert Dennis is an expert for Continuous Integration and Development Processes. He has introduced Agile Processes in the distributed world and now got involved with the mainframe. Mainframes are so slow all the time, if I want a system provisioned it always takes ages to get what I need to provide good service for the developers. Modernization Matthias Application Analyst Matthias is an Application Analyst and sometimes also Archeologist. He has a lot of experience in modernizing applications and the analysis of existing and mostly poorly documented applications. Never touch a running system that saying is more than true for our environment. If our developers want to implement new features, they avoid modifying and reusing existing code where possible. After all, they feel that writing new code is faster and more fulfilling. However, quality and complexity have suffered under this mindset.

11 Meet the Developers Integration Isabel API Designer and Developer Isabel is a Developer that was highly involved in the introduction of Web Services in the distributed World and also has some experience with mainframes already and now lead the development efforts to introduce RESTful APIs. Liberty Lars Developer and UX Expert Lars is a new hire fresh from university and has a lot of experience with bleeding edge technology and quickly established himself as expert for user experience and frontend design. The mainframers always think in past technologies and if you ask them for APIs they talk about copybooks and APPC. I guess I need to use some servers with existing connectors and build a façade What are these Mainframes? Never heard of them? Are they useful? Can they even perform modern tasks or just this oldschool 3270 stuff?

15 Why we use Blockchain in this use case Blockchain is a Technology a lot of people speak about today and so it was an idea to use this new technology for the business usecase we see here It is a technology that enables to work jointly with health records and secure privacy on all levels of interaction Previously long running manual processes can be automated and increased TODO TOBI

18 Reuse instead of rewrite - using IDz und IBM Application Discovery Rewrite?? Reuse? Requirements? Maintenance? Faster? More Effort? Which Code? Existing Code is a valuable asset You can t change or reuse existing code without understanding it first!
