Microservices 

Microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.

Docker

• A technology for building/running in an isolated operating system.
• Provides process/resource isolation while running in a single OS Kernel 
• Different from vm, lighter, faster, easily integrated

Container creation

Container orchestrators

Kubernetes

• Powerful system for running containers
• Pods
• Services
• Replication controllers
• Rolling updates
• Scale and Autoscale

How do we connect?

Docker on kubernetes

System evolve

• No system is ever "done"
• All of your microservices will change
• Deployments are necessary

System evolve

CI Practices

• Use a CI Server (Jenkings, Team Services, Bamboo, Travis CI, etc) with parallel tasks.
• Create a process (build) for each service
• Each process compiles, build image, tag image and run tests
• One to one mapping between sources and images
• Run tests inside container (Optional)
• Run full system test using docker compose

CI Pipeline

Cross-cutting concerns

• Logging (ELK, Application insights, Google monitor, etc)
• Security (DNS, Https, certificates, etc)
• Caching (CDN, redis, etc)
• Metrics
• Scaling
• Multi-tenancy (Namespaces, subnets, policies, etc)
