I had the chance to attend JaxDevOps London, here is a valuable session from Daniel Bryant about the common mistakes done for Microservices…

1.  7 (MORE) DEADLY SINS:
   1. Lust [Use the Unevaluated Latest and Greatest Tech]:
      1. Be an expert on Evaluation
      2. Spine Model: Going up the spine solves the problems, not the first step: Tools, but Practices, Principles, Values, Needs.
   2. Gluttony: Communication Lock-In
      1. Don’t rule out RPC [eg. GRPC]
      2. Stick to the Principle of Least Surprise: [Json over Https]
      3. Don’t let API Gateway murphing into EBS
      4. Check the cool tools: Mulesoft,Kong, Apigee, AWS API Gateway
   3. Greed: What Is Mine [within the Org]
      1. “We’ve decided to reform our teams around squads, chapters, and Guilds”:  Be aware of Cargo-Culting:
   4. Sloth: Getting Lazy with NFR:
      1. Ilities: “Availability, Scalability, Auditability, Testability” can be Afterthought
      2. Security: Aaron Grattafiori DockerCon2016 Talk/InfoQ
      3. Thoughtworks: AppSec & Microservices
      4. Build Pipeline:
         1. Perfromance and load testing:
            1. Gatling/JMeter
            2. Flood.IO [upload Gatling script/scale]
         2. Security Testing:
            1. FindSecBugs/OWasp dependency check
            2. Bdd-Security (Owasp Zap)/ Arachi
            3. Gaunltl /Serverspec
            4. Docker Bench for security/Clair
   5. Wrath: Blowing Up When Bad Things Happen
      1. Michael Nyard (Release It) : Turn ops to Simian Army
      2. Distributed Transactions:
         1. Don’t push transactional scope into Single Service
         2. Supervisor/Processor Manager: Erlang OTP, Akka, EIP
      3. Focus on What Matters:
         1. CI/CD
         2. Mechanical Sympathy
         3. Logging
         4. Monitoring
      4. Consider:
         1. DEIS
         2. CloudFoundry
         3. OpenShift
   6. Envy: The Shared Single Domain and (Data Store) Fallacy
      1. Know your DD:

                  2. Cassandra
                  3. Graph -> Neo4J, Titan
                  4. Support! Op Overhead
   7. Pride: Testing in the World
      1. Testing Strategies in a Microservice Architecture [Martin Fowler]
      2. Andew Morgan [Virtual API Service Testing]
      3. Service Virtualisation:
