Mainframe often termed old world juggernaut of software industry, but still holds large trillions of data in Banking, Insurance, Travel, Hospitality industry, has an impeccable track record of robust processing and security. But often the fast changing Digital world and Mobile eco system, manifests a challenge to Mainframe systems, in terms seamless compatibility. So that organizations can leverage competitive edge to have mobile eco system as part of their IT solution to gain the dynamic edge yet leverage Mainframe as their system of records to leverage stability.

In this talk will share a generic case study of major bank how they leveraged in making their Mainframe eco system nimble and compatible with Mobile eco system using Agile, Devops and Micro services in tandem to leverage competitive advantage and cost savings.

Opening the Mainframe world to Mobile Ecosystem in a seamless and beneficial way.

  1. 1. OPENING THE MAINFRAME WORLD TO MOBILE ECOSYSTEM IN A SEAMLESS AND BENEFICIAL WAY. Vishal Venkatesan 1st – 3rd December, 2017 | Westin, Hyderabad, INDIA
  2. 2. INTRODUCTION • Vishal Venkatesan • Principal Agile Consultant with the Global Agile CoE, Mindtree • Education: BE (E&C) • Certifications: • CSM, SAFe Agilist, ITIL Certified, Devops Certified – (Devops Institute) • SCRUMStudy Certified Agile Trainer (SDC, SMC, SPOC) • Domains: • BFSI (Banking Financial Services And Insurance), • Telecommunications, • RCM (Retail, Consumer Processing Goods, Manufacturing) • Experience: • 15 years Software Delivery, 10 years Agile Coaching, Agile Business Analysis, Agile Process Consulting, Agile Training. • Linkedin: https://www.linkedin.com/in/vishal-venkatesan-1bb29b45 • Author: • Book - ‘Enterprise Scaling And Sustaining Of Agile’
  3. 3. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. • System z and z/OS have a long history of providing support to critical business. These systems, often backed by DB2, are repositories for vast amounts of business transactions and data • World's top 25 banks run IBM z Systems, as do the 10 largest insurance companies and 18 of the top 25 retailers. • But there is little question that mobile computing is playing a significant role in today's I/T landscape. • From banking applications to airline flight status apps to insurance claim apps, mobile devices are in wide-spread use. • In fact, it is often seen as a competitive advantage to have mobile functionality as part of your I/T solution • This leaves us with a QUESTION can the robust Mainframe World and new age Mobile World co exist or organization need to embark huge cost centric transformation programs to move away from Mainframe World to be part of new era competitively
  4. 4. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. The Challenge • Mobile devices tend to make use of standard protocols and standard data format packaging, while some z/OS systems do not accept those formats • This often leads data being configured or massaged to support transmission between Mobile frontend and Mainframe backend • In many an organization there are separate teams often christened as ‘Integration Teams’ with sole purpose of making data compatible between SoE (System Of Engagement like Mobile front end or new age front ends) and SoR (System Of Records which can be Zos Mainframes) • In many other organization there are huge transformation programs to move SoR to new age platforms and technologies
  5. 5. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. Let’s Examine The Challenge • Separate ‘Integration Teams’ with sole purpose of making data compatible between SoE and SoR can become an overhead technology teams giving intermittent but crucial technology value but no Business Value • Huge transformation programs to move SoR to new age platforms and technologies can be risky (given trillions of data in SoR) even if there is budget to fund • But wait should we change a performing system • Mainframe performance • Can well handle over 100,000 transactions per second. That kind of performance is important, given that analysts predict anywhere from 20 billion to over 50 billion connected devices by 2020 in crucial • IBM z13 is the most modern mainframe server hardware available today it uses less power than a clothes dryer, but has more processing power in one small footprint than a room full of servers.
  6. 6. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. Let’s Explore The Solution To The Challenge • At the onset Mobile Ecosystem as new age SoE and Mainframe Zos as robust SoR make ample business and technical sense to co exist • But can they co exist • Options (1) • Zos Connect • What is Zos Connect z/OS Connect is software function written to run inside Liberty Profile for z/OS and serves as an enabler of connectivity between the mobile environment and backend z/OS systems:
  7. 7. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. • Technical Solution To The Challenge • Let’s explore the “Technical Solution To The Challenge” • z/OS Connect is designed to accept REST URIs and JSON data making it compatible with a wide variety of devices and systems. • SoE (Mobile Application Developers) need only to understand RESTful APIs and the JSON data requirements for the service exposed by z/OS Connect and need not worry of details of SoR (Mainframes/ System Z). • The owners of data i.e. SoR becomes exposures of data eliminating extra layers or teams which is cost effective as well. • Also who can better map Mainframe Data Structures to JASON Data Structures than owners of those transaction i.e. SoR (Mainframes/ System Z). • There various protocols to map nimbly basically in form of bind file which describes the relationship between JASON data structure front end and Mainframe copybooks back end.
  8. 8. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. • Technical Solution To The Challenge • Let’s explore the “Technical Solution To The Challenge” • We seem to have banished the technical bottleneck to enable a seamless co existence of Mobile Eco System and Mainframe world each leveraging its advantages and reach • But does this “Technical Solution” suffice holistically • Also Zos Connect is only one option to solve this challenge in the market there could a plethora of API connects • Not getting deeper into Technical Options to the solution which each comes with its own advantages and cost • Lets explore the “Holistic Solution To The Challenge” also “Technical Solution To The Challenge” we just discussed forms an important preamble and precursor
  9. 9. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. Holistic Solution To The Challenge Let’s explore the “Holistic Solution To The Challenge” Technical seamlessness Zos connect or any such peer/ competitor API connects gives is an important preamble But it is far from being holistic Lets Sample few reasons
  10. 10. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. Most SoR (System Of Record – Mainframe Zos Team) follow Robust but elegant Software Development Life Cycle New age Continuous Integration, Continuous Testing and Continuous Deployment tools don’t quite fit in or not explored enough Robust but elegant Enterprise Release Cycle for Deployment, Deployment of code is an achievement not a routine Most SoE (System Of Engagement – Mobile App etc Front End Development Team) follow Nimble, Software Development Life Cycle New age Continuous Integration, Continuous Testing and Continuous Deployment tools fit in rather their technology enables this Nimble Deployment Cycle, Deployment of code is a routine not an achievement SoE and SoR cannot have handoffs but need a collaborative handshake else cycle time and lead time shoot up
  11. 11. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. Are we getting into a situation ‘Hare Communicating With A Tortoise’ Though there is an old analogy who can “Win The Race Let’s explore can we make System Of Records (SoR) – Mainframe System Z nimble Firstly SoR teams need to be groomed to be able to ‘Deliver Value In A Time box’ Ability of teams to ‘‘Deliver Value In A Time box And Every Time boxed Sprint’ is what in a nutshell Agile is!? LEARNING AGILE How can SoR team be Agile Enabled if that is the right word Firstly SoR team associates need to made cognizant of Agile make them Cognizant of if not Brilliant at Basics Of Agile (Agile Manifesto and Agile Principles) Slowly get them into a growth mindset from fixed mindset or even an hybrid mindset DOING AGILE Get the SoR team into a Agile Cadence, make them used to work in sprints i.e. Participate ably in Agile Ceremonies Stand Ups, Retrospective, Showcases, Sprint Panning i.e. Understand use of Agile Artefacts Product Backlog, Sprint Backlog, Burn down Charts etc i.e. Blend Agile Roles in SoR - Scrum Master, Product Owner and Cross Functional Team either organically or inorganically
  12. 12. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. Thus in a nutshell the SoR Mainframe System Z is traversed through an exciting journey of Learning Agile - Tangible Gain Staff level uplift in Agile – Growth Mindset Doing Agile - Tangible Gain Team level uplift is gaining from Agile Cadence The important next step is to enable the SoR Mainframe System Z to Being Agile What is Being Agile Teams have embedded Agile Growth Mindset with ability to Deliver from Concept to Cash potential but business usable increments Thus delivering faster Business Value with out compromising the stability of the system Speed to Potential Customer Value Reliable Stability Nimble Architecture
  13. 13. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. How can we enable SoR Mainframe System Z Being Agile
  14. 14. Opening the Mainframe World to Mobile Ecosystem in a seamless and beneficial way. An Agile Team cutting through technologies i.e. SoE, SoR if possible SoI focusing on nimble potential business value increments is a precursor The teams focus on nimble end-user value rather than intermediate technology value which is crucial but no end-use quotient They use technologies like Zos connect to enable way of working as handshakes not has handoffs Slowly these teams graduate to becoming more T shaped skilled Core Skill Areas Ability to work out side core area Agile Stories Cut Through Technologies To Derive Nimble Business Value
