Application Transformation Workshop

  1. 1. © Copyright 2018 Pivotal Software, Inc. All rights Reserved. Version 1.0 The Journey to Pivotal Cloud Foundry Application Transformation Start Small and Scale Fast
  2. 2. Your Application Portfolio is a Mix of Things CONTAINERS EVENT-DRIVEN FUNCTIONS DATA MICROSERVICES Batch MONOLITHIC APPLICATIONS ESBJEE COTS MAINFRAME .NET
  3. 3. To Start the Journey Getting apps to run on PCF 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
  4. 4. Pick Applications That Matter TECHNICAL BUSINESS Why Move? ● Licensing costs ● Time-to-market factors ● Revenue opportunities ● Business criticality ● Risk tolerance ● Change frequency What Can we Move? ● Framework / runtime ● Architecture design ● Statefulness ● Use of proprietary tooling ● Dependencies / integration ● Usage / workload Org Factors (the “When” and “How”) ● Domain expert availability ● Lifecycle stage ● Calendar dependencies ● Etc. The App Tx Funnel A framework for disposition planning, prioritization and governance
  5. 5. Understand the Path to Production Sample: Banking Customer 65 Steps consisting of 45 days of wait and 180 days of process time for a total cost, per new application, of $150,000. ● Workshop to define the basic process baseline ● Break down the larger steps into detail ○ Steps ○ Who is involved ○ Time required ○ Dependencies ○ Average cost ● Flag areas of potential automation ● 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
  6. 6. Application Transformation Strategies Re-Host Containerize aka “lift and shift” Re-Platform Minimal efforts to run natively on PAS Re-Factor Convert to Cloud Native aka “Modernize” Re-Build Decompose and rewrite from the ground up Application Portfolio Funneling Process
  7. 7. Your Code As a Crime Scene: App Foundry Automated suitability assessment and decisioning framework. A free tool from Pivotal to help accelerate good decision making along the path to PCF. Upload binary or map to source control Parsers for most common languages (Java, .NET, PHP, Ruby, etc.) Extensible rules (100s available currently) UI dashboard to help triage decisioning Understand technical effort to move your app
  8. 8. Build Program Artifacts We accelerate team velocity using a “cookbook” filled with recipes written by developers as new patterns for transformation and legacy interoperation are discovered through hands-on work. Recipes are written in Git markdown. The Cookbook is a PCF site, includes search and is assembled using a CI pipeline
  9. 9. How Successful Customers Scale Quickly Small product team that services internal customers while automating everything. PLATFORM AS PRODUCT Hands-on training (and train- the-trainer) for Application Developers and Architects CxO dashboard of aggregated success metrics. OKRs at project level keeps the work & aligned. Apps on PCF BU or geo based “move hubs”. Velocity through pairing, rotation and reuse. Incremental results. APPLICATION TRANSFORMATION + EDUCATION AND ENABLEMENT “5S” METRICS Starter Define a funnel and path-to-prod process. Push initial app(s). Learn a lot. Prod Dial Tone Assemble a Platform team. Deploy PCF with a prod dial tone. Day 2 Platform team automates more, staffs up, settles into day 2 concerns. A Few Projects Targeting progressively more complex workload. Usually within a single geo and/or BU. Enablement Create program; train people staffed on App Tx projects Move Hubs Transition from project to program with multiple “hubs” on a geo / BU basis. BIG Wins Measurement starts on day 1 but is magnified as workload increases (as driven by the App Transformation Program!)
  10. 10. But Why? Why Do This AppTx Thing? Note 1: 2017 & 2018 Pivotal customer case studies. n=15. “Process Time” = hands-on work (vs. “total time” being the time to deliver). Note 2: Averages are exclusive of highest and lowest measures. 37% more time coding 37% relative improvement in time spent coding (from 56% to 77%) 21% absolute improvement in time spent coding (from 56% to 77%) 90% faster 61% faster 90% time reduction 87% process time reduction Total time: from 65 to 6 days Process time: from 81 to 11 hours 61% time reduction 82% process time reduction Total time: from 14 to 5 days Process time: from 115 to 21 hours 69% time reduction 74% process time reduction Total time: from 79 to 24 hours Process time: from 34 to 9 hours 69% more efficient DevelopingProvisioning Operating (Day 2)Releasing Software Development Lifecycle On-going Ops 82% average reduction in ‘path to production’ time (from 84 days to 15 days)
