11 Microservice or monolith Microservice Architectural approach that emphasizes decoupling complex functionality into smaller, independent (micro)services Each microservice consists of simpler functionality with fewer, focused concerns that can only be accessed via well defined interfaces (i.e. callers cannot rely on knowledge about underlying implementation details). A collection of microservices jointly comprise an application, and each microservice is independently deployed, scaled, managed. Effectively deploying and operating Microservices heavily relies upon automation (e.g., CI/CD, container orchestration, etc.). Monolith An architectural approach that results in an entire application being self-contained and consisting of multiple related but distinct modules being bundled, deployed and run together in the same process and/or server. Most web application deployed to app servers (e.g. Weblogic, Websphere, JBoss, etc.) fall in this category. 11

Reduce feedback loop using testdriven development to surface problems sooner and be responsive AGILITY.

13 Continuous integration and delivery Deliver high quality software faster and continuously, from idea to production AUTOMATION. Integrate tools and automate processes from testing to builds and deployment SPEED. Release more frequently with smaller bits will reduce complexity and improve time-to-market QUALITY. Reduce feedback loop using testdriven development to surface problems sooner and be responsive AGILITY. Push updates on regular basis with no downtime to improve customer experience and time to market Build Pipeline Operations Commit Code Change Automate Build & Test (Unit Test, Static Code Analysis) Store Binaries & Build Artifacts Automated Integration Testing Acceptance, Performance & Load Zero Downtime Upgrade to Production Tool Chain GitlLab Jenkins archiva Development Test + UAT + Staging Production Share binaries and manage distributions. Manage artifact lifecycle. Develop, test, QA and production on the same platform. Simple, developer friendly commands and APIs. Operational benefits for every app. Built-in ecosystem services. Deploy, operate and scale on any IAAS 13

14 MyService360 and Pivotal Cloud Foundry How did this improve the development process? Shorter lead time from requirement to delivery Automated deployments make a build available for QA earlier in the development sprint Consistent environments allow development and deploy with confidence Spring Cloud integration with PCF simplifies the process of creating a new microservice Easy integration from PCF with ELK for logs and New Relic for monitoring PCF makes it easier to pick the language most suited for the task PCF makes it easier to try technologies from the marketplace 14
