The Journey to Cloud “We need to get 200 apps
running in production on cloud
within the next few months.”
“We’ve been modernizing [...]
for the past year. Great, what
do you have running? Nothing.”
“My boss wants a plan to get
4,500 apps into cloud within
the next 2 years.”
“I’d like to get a work stream per
BU spun up so all 25 are working
in parallel – later this year.”
“We’d like to use the Strangler
Pattern and move order processing
from Mainframe to cloud”](https://image.slidesharecdn.com/accelerateapplicationmigrationaug5-200805162028/85/Accelerate-Application-Migration-August-5-2020-6-320.jpg)

Risk: Fail to get quick wins to build momentum. ➔ Horizontally focused project work. Often we address painful symptoms in an IT-centric “horizontal” manner. Risk: You miss root cause and don’t deliver business impact ➔ Your mess for less. Instead of making meaningful changes, you’re moving apps from one host to the next. Risk: Won’t get the business-centric benefits you desire. ➔ One-time project versus competency development. Efforts attempt to “finish” versus build a practice. Risk: Not set up to continuously keep technical debt low. Typical Modernization Approaches

What We Believe ● You Should Move Apps to VMware Tanzu 😃 ● Plan Just Enough to Start ● Define Hard Goals and Measure Them ● Start With “One Thing” ● Automate Everything You Can ● Build Skills by Pairing and Doing ● Use Real Work to Inform Strategy
- 9. Confidential │ © 2020 VMware, Inc. 9 How to Get Started Getting apps to run on cloud is easy. Policy, regulation, manual process, organization and politics is hard. Tackling these things can take time so let’s start right away. Let’s really dig into the path to prod and define the value stream. Identify the manual process and bottlenecks. Figure out how we measure near-term success. Do it with working code. identify a small set of apps define a Funnel to make decisions Baseline the Path to prod Fire a tracer bullet to validate assumptions and push on path to prod constraints

Workshop to define a baseline Break down the larger components into: • Steps • Who is involved • Time required • Dependencies • Average cost Flag automation opportunities Identify the full duration of time and cost Take “1” app and run through the process • Validate / invalidate assumptions • Try to automate in low-risk way Use as roadmap for subsequent steps

Modernize Complex Systems Find apps representative of the portfolio. Make a minimal set of testable changes in order to get them running on cloud. 1. Push / containerize the app 2. See what fails 3. Write a test 4. Get the tests to pass 5. Write down your recipes Understand the system. Define future-state. Decompose and migrate “thin slices” to cloud and enable coexistence with remaining parts. 1. Find the seams 2. Carve out features into microservices 3. Build interop code around seams 4. Write tests 5. Get your tests to pass APP APP µService µService
