AWS Compute Week, Day 2: Docker

Docker With ECS (Elastic Container Service)

Why containers? OS virtualization, Process Isolation, Images, Automation Portable Flexible Fast Efficient Hard to switch over to batch jobs unless you have a cluster manager Amazon ECS is a cluster management tool Mix and match the different EC2 instances for your different container images ECS scheduling will do everything for you Optimistic, and strict scheduling Optimistic tries to reserve, if fails, then fail Other waits for completion before it works // block it out No built in queue in ECS Fully managed elastic service Shared state optimistic scheduling Deep integration with other AWS services Load balancing, block storage, etc. etc. Routing via Application Load balancer Path based routing Dynamic port mapping HTTP/2 WebSockets Detailed Logging Task Definition

Deep Dive on microservices and Docker/Containers

Microservices Architecture, ECS, Placement, and 12factor App What is a microservice? Small independent stateless process communicating with API?s. Small and focused on doing a small task which lets you have a modular approach to system building Monolithic vs Microservices Build it all inside a package and put it on a webserver (but makes it hard for new features or bugs) Make a change in the singular service you need Black boxed
