Containers: A natural fit for microservices

Simple to model; any app, in any language

Portable, Fast, Efficient

Built in versioning

Test & deploy same artifact

Stateless servers decrease change risk

What is Amazon ECS?

Amazon EC2 Container Service (Amazon ECS) is a highly scalable, high performance container management service.

You can use Amazon ECS to schedule the placement of containers across your cluster.

Amazon ECS will maintain the state of your cluster, ensuring availability of your containers and tasks .

Container Management at Any Scale

Nothing to run

Manages resources & availability

Control and monitoring

18 Months~1500 EC2 instances

Critical Production workloads

9 Months Aggressive containerization

using Docker + ECS

Honorable Mention: Lambda

Why do we need containerization?

Rapid growth is one of the nicer problems to have

Why do we need to evolve?

Growth necessitates change

“Ch-ch-ch-ch-chaaaaaanges”

Organizational change

• Adopted a squads/tribes model• Localized ownership of services• “You build it, you run it”• Remove bottlenecks to delivery• Delegation of previously

centralized capabilities

Architectural change

• Adopt Cloud• Monolithic code releases are

too slow• Loosely coupled

microservices• Data driven experiments• Automate all the things

Enabling change in a non-scary way…

Developer Enablement Tribe

• AWS Architectural guidance• Set and enforce best practices• Provide internal training• Create reusable code snippets• Build automation and deployment tooling • Provide template microservices containers• Maintain shared platforms and tooling• Handle shared VPC’s, Direct connects, DNS,

SSL.• Co-ordinate cost management activities• Perform vulnerability auditing and testing • Run demo’s and showcases• “Eat the dogfood”• Etc….

MBA Conan! What is best in life?

“To accelerate your product delivery --

Satisfy your users needs faster and better,

How?• Containerized Microservices• In-house automation tooling • AWS API driven infrastructure

Hands up if you’re a developer!Does your development/deployment pipeline look a bit like this?

Why Microservices?
