Agile Tour Pune 2015: Agility with Microservices and Devops: Archana Joshi and Yatin Kulkarni

  1. 1. AGILITY WITH MICROSERVICES & DEVOPS Archana Joshi & Yatin Kulkarni Cognizant
  2. 2. State of the Union – Where are we heading? • Digital Disruption, • Way of working is keeping pace • Architectural paradigms are lagging
  3. 3. Microservices – Modularity on steroids! •Origins in philosophy •2005 – web-services •2011 – Services
  4. 4. Microservices – Modularity on steroids! microservices is a software architecture style in which complex applications are composed of small, independent processes (based on business) communicating with each other using language-agnostic APIs (Source: wikipedia)
  5. 5. Microservices – Early adopters
  6. 6. Microservices – One of the top trends Microservices - Essential to produce a continuous digital experience Source: Gartner Oct 2015 – Top 10 technology trends for 2016 Source: MuleSoft 2015 survey of 300 IT decision makers (ITDMs) to assess how organizations of all sizes are implementing and planning for APIs
  7. 7. DevOps – Collaborate and Automate Baked-in collaboration Cross-functional teams and skills Continuous delivery Small, frequent updates Instant deployments Quick transition in the app lifecycle Automation Real-time visibility and updates Development and operations aligned Reduced service disruption Quick value delivery Increased volume of new applications, updates and patches Streamlined processes Time to market Service quality Risk management Agility
  8. 8. Agile, Microservices, DevOps – A “ménage a trois” made in heaven! • Dependency management simplified • Well suited for large distributed teams by dividing work across pairs, locations • High technical debt associated with adopting microservices can only be managed through appropriate DevOps tools • DevOps takes center stage instead of being an after thought by becoming an integral part of the process
  9. 9. And the rubber hits the road – SOA to Microservices in 3 “easy” steps… • Step 1 – Modularize your service silos by applying Domain Driven Design (DDD) specifically Bounded Contexts • Step 2 – Adopt a PaaS platform for the build process – Heroku, CloudFoundry, etc. • Step 3 – Adopt a container technology for deployment - Docker, LXD, etc.
  10. 10. Step 1 - Better Agility through Domain Driven Design • Small Teams (no more than 4 developers) per Bounded Context • Decentralized data store design to reduce dependencies • Promote use of polyglot persistence across various data stores • Manage data consistency challenges through use of MDM tools to ensure eventual consistency • Employ Contract Driven Development • Choose most appropriate technology for a given Microservice • Abide by the other principles of The Twelve Factor App (http://12factor.net/)
  11. 11. Example of a classic SOA based application Service Deployments Primary Data Store Replicated Data Store Web Apps Web Store Fulfillment Call Center Customer Management Order Management Logistics Management Inventory Management Mobile Apps Customer Internal Content Management Partner Systems Service Gateway (Typically an ESB)
  12. 12. Microservices based Application architecture Service Deployments Web Apps Web Store Fulfillment Call Center Mobile Apps Customer Internal Content Management Partner Systems Service Gateway (Typically just a Load Balancer)
  13. 13. Step 2 – Better Agility through Continuous Integration Done Right • Use platforms such as Heroku/Cloud Foundry/Docker to – Internalize environment/configuration management so as to achieve Dev/Prod parity – Promote use of immutable instances and thus horizontal scalability – Allow for service evolution through versioning with minimal disruption – Instutionalize the use of “Operationalized Architecture” so that DevOps (CI/CD/Monitoring) become a first class concern • Plan for complete test automation including functional and integration testing
  14. 14. Step 3 – Better Agility through Continuous Deployment & Monitoring • Adopt container based deployment to optimally utilize available compute and storage resources by – Deploying a single microservice per container – Leveraging Blue/Green Deployments to minimize risk – Managing Scalability for individual microservices • Leverage appropriate monitoring tools to be able to respond quickly and efficiently manage failures. • Introduce platforms for API management and discoverability (Apigee, Apis.io, etc) to promote adoption and reusability • Invest in Networking as a Service tools (SDN, Fan, etc) for managing large scale microservices deployments
  15. 15. The future is here – Everything you need to build Microservices in a box AWS Lambda Spring Cloud Azure Service Fabric
