Agenda

• Amazon EC2 Container Service• Amazon EC2 Container Registry• Common patterns• Demo

Amazon EC2 Container Service

Easily manage clusters for any scale

• Nothing to run• Complete state• Control and monitoring• Scale

Flexible container placement

• Applications• Batch jobs• Multiple schedulers

Designed for use with other AWS services

• Elastic Load Balancing• Amazon Elastic Block Store• Amazon Virtual Private

Cloud• AWS Identity and Access

Management (IAM)

Designed for use with other AWS services

• AWS CloudTrail• Auto Scaling• CloudWatch Logs

Extensible

• Comprehensive APIs• Open source agent• Custom schedulers

Amazon EC2 Container Registry

Fully managed

• Nothing to run• Control and monitoring• Scale

Secure

• IAM resource based policies• Transfer via HTTPS• Encryption at rest

Simplified Workflow

• Tight integration with Amazon ECS

• Use Docker CLI commands (e.g., push, pull, list, tag)

Highly Available

• Backed by Amazon S3• Images redundantly stored

across multiple facilities and multiple devices in each facility

Common Patterns

Pattern 1: Services and applications

• Simple to model• Micro services• Blue/green deployments

Pattern 2: Batch jobs

• Share resource pools• Ideal for bursty jobs• Spot instances

Amazon ECS Terminology

Amazon EC2 instances

Docker daemon

Amazon ECS agent

Key components: container instances

Regional

Resource pool

Grouping of container instances

Start empty, dynamically scalable

Key Components: Clusters

Key components: task definitions

Volume definitions

Container definitions

Unit of work

Grouping of related containers

Run on container instances

Key components: tasks

Key components: Run a task

Good for short-lived containers, e.g.

batch jobs

Key components: Create a service

Good for long-running applications

and services

Key components: Create a service

• Load balance traffic across containers• Automatically recover unhealthy containers• Auto Scaling• Discover services

Elastic Load Balancing

Key components: Update a service

• Scale up• Scale down

Elastic Load Balancing

Key components: Update a service

• Deploy a new version• Drain connections

Elastic Load Balancing

Typical user workflow

I want to run a service.

Typical user workflow

Run Instances

Amazon EC2

Use custom AMI with Docker support and

ECS agent. Instances register

with specified cluster.
