Shortcomings

Automation

Continuous I/D/D

Infrastructure Orchestration

● Environment as a code● Provisioning automation● Configuration automation

Immutable Infrastructure

● Build● Run ● Destroy

Disposability

● Container as deployment artifact● Environment agnostic● New version - new container● All dependencies built in

Containerisation

Tools

Gradle http://www.gradle.org/

Gradle - is build automation

evolved.

● Combines the power and flexibility of Ant

with the dependency management and

conventions of Maven

Takes an opinionated view of

building production-ready Spring

Docker https://www.docker.com/

Docker - An open platform for

distributed applications for

with zero downtime and more

Redis http://redis.io/

Redis - is an advanced key-value

cache and store

● open source - BSD licensed

● referred to as a data structure server (key-

value store)

● super fast read/writes

● provides messaging (queue/pubsub)
