Editor's Notes
- 1. Zero Dollar Migration Program · There are many key elements a customer considers before moving to Pivotal. Two of the biggest barriers are Bubble Cost for migration & operating cost of Pivotal + Cloud. Our presentation will consists of multiple tracks which drastically lowers the cost of Pivotal migration, coupled with our creative engagement model which manages bubble cost issues. · Audience for such session would be primarily senior management – CXO’s, business & Directors or Senior architects.
- Good Afternoon everyone! I am here to deliver 3 key takeaways today 1st, Why cloud modernization over cloud migration 2nd, What specific steps you need to take And 3rd, How do you make the economics work
- Why cloud modernization instead of cloud migration? No carry-over of your technical debt - Once the application is modernized, application will be completely new from the architecture design perspective No big bang approach - Instead of one time big upgrade we recommend modernization be spread over a period of time with smaller deliverables. This will also enable no-downtime. Lower cost of execution - We focus primarily on getting value in smaller chunks while upgrading the core architecture. Lower risk - Since the changes are performed in smaller chunks risk of execution is also pretty low.
- What is $0 dollar modernization? Free up cash from expensive middleware - This approach works very well with applications which use the likes of WebSphere and WebLogic as their application containers. Use the free cash to fund Application Modernization - This is an approach which allows modernization without any additional budgetary support. Other resulting benefits of this approach Modernize at your own pace - Since the application is migrated to cloud at the very first step, there is no organization pressure of being cloud-enabled. Also knowing that in-production applications are critical in nature execution can be spread over a period of time. Spreading over time also ensures no disruption. Cloud enabled during modernization - Applications are migrated to the cloud at the very first step. This way application is always available in the cloud while it is been modernized. Harness the power of cloud native - End objective of this modernization approach is to harness the power of native technologies offered through the cloud platforms.
- Why should enterprises adopt this model? Business Need Driven Modernization We take the capability based approach during the re-designing of the architecture. These capabilities would belong to a domain, enabling re-usability across enterprise. This process also eliminate, antiquated technologies from the application architecture Better TCO Lower technology debt results to lower overhead Lower risk results in higher yield for your investment Faster time to market Pre-conceived execution plans and standardized architecture patterns allow faster time to market Let's compare these two charts here What you see on the left side is the traditional big-bang approach. Here you build everything at once and go-live. This kind of approach is expensive and adds lot of risk to the system What you see on the right is an approach where we build the system incrementally. A technology chassis, is built which works as the foundation for the long term demand of the system. As said earlier features are extracted out of the old system and capabilities are added to this chassis. If you follow the red curve you will see that technical debt goes down and new system gets build.
- Steps for modernization There are 4 stages to this process Re-platform - As a 1st step we migrate the application to PCF. It is very similar to cloud lift & shift. But the advantage here is, it runs on PCF at a very early stage of the modernization journey. Modernization - At this stage we start applying offerings of Spring and PCF e.g. Spring Boot Transformation - We carve out capabilities and start building independent Microservices. This also opens the application for external consumption Microservices / API First - At this final stage the monolithic code would have been deconstructed and application is ready to enjoy the features of new architecture
- Example of pre-migration Application Architecture You can see here that WebSphere has been used as an application container Also Websphere requires that it run on the AIX platform There are bunch of other services which are not tightly-coupled to the core application
- Example of post-migration PCF Architecture Earlier I shared how a WebSphere architecture looked on AIX On this slide you can see how the architecture looks within PCF. This is almost L&S but the application is running on PCF You can see PCF services available to the application. Not used at this stage but still available for all future demand
- Lift & Shift considerations You can see log, session, caching etc. in this list Rule of thumb is to remove all the dependencies from the underlying operating system This way application is ready for cloud enablement Let me quickly walk you through this list
- Iterate to Microservices/API First This is a sample process of building capabilities. It is repeated till the application is 100% Microservices enabled. Post that all updates are done following the "API First principles".
- How to pay for it? There are 3 parts to the free cash flow 1. hardware, 2. license and 3. Ops In this example you can find a savings of 75%(which is approximately $1.5M) If you look at the %-savings from each of these groups, operations contributed most of the savings
- I hope I was able to deliver 3 messages I mentioned at the beginning of the session. Before moving to the Q&A let me answer some of the questions frequently asked by my clients F A Qs Q. Do I have to build a 12 factor Application to run on PCF? A. No. It is not mandatory. Q. Can I migrate my application to PCF? A. Yes. Applications which follow certain architecture patterns can be migrated to PCF. Q. Do I have to re-write my application to run on PCF? A. No. If the application follows certain architecture patterns then only minor configuration changes would be needed. Q. Do I need a PCF AI(App Instance) for each of my Microservices? A. Depends on the definition of Microservice.
