Without Container : How to pack ? How to load / unload ? How to transship ? How to check dependencies ? How to protect ?

Container related sessions in re:Invent 2014
Docker is an open platform for developers to build, ship, and run distributed applications in Linux containers. In this session, Nathan LeClaire, a Solutions Engineer at Docker Inc., will be demonstrating workflows that can dramatically accelerate the development and deployment of distributed applications with Docker containers.
Through in-depth demos, this session will show how to achieve painless deployments that are both readily scalable and highly available by combining AWS's strengths as an infrastructure platform with those of Docker's as a platform that transforms the software development lifecycle.
If you have tried Docker but are unsure about how to run it at scale, you will benefit from this session. Like virtualization before, containerization (à; la Docker) is increasing the elastic nature of cloud infrastructure by an order of magnitude. But maybe you still have questions: How many containers can you run on a given Amazon EC2 instance type? Which metric should you look at to measure contention? How do you manage fleets of containers at scale?

Container related sessions in re:Invent 2014
Container technology, particularly Docker, is all the rage these days. At AWS, our customers have been running Linux containers at scale for several years, and we are increasingly seeing customers adopt Docker, especially as they build loosely coupled distributed applications. However, to do so they have to run their own cluster management solutions, deal with configuration management, and manage their containers and associated metadata. We believe that those capabilities should be a core building block technology, just like EC2. Today, we are announcing the preview of Amazon EC2 Container Service, a new AWS service that makes is easy to run and manage Docker-enabled distributed applications using powerful APIs that allow you to launch and stop containers, get complete cluster state information, and manage linked containers. In this session we will discuss why we built the EC2 Container Service, some of the core concepts, and walk you through how you can use the service for your applications.

What is container – OS Virtualization
Containers are isolated,
but share OS kernel and, where appropriate, bins/libraries
…result is significantly faster deployment, much less overhead, easier migration, faster restart

Make the containers easy to use, standardized, interoperable
• Container technology has been around for a while (c.f. LXC, Solaris Zones, BSD Jails)
• Shipping containers are not just steel boxes.
• With Docker, low-level containers get the following:
-Ease of use, tooling
-Re-usable components
-Ability to run on any Linux server today: Physical, Virtual, Cloud, …

Docker is a shipping container for codes

Why are customers running Docker in the cloud?

Easy deployments with API
Standardized environment fidelity
Better fleet management
Distributed applications
Cloud is programmable and automated environment
… Good fit to Docker

Tasks Containers Clusters Container Instances

Task: A grouping of related containers
Nginx Web Server
Rails Application
MySQL Database
Log Collector
… about entire architecture not just a container

Task Definition
{ “family” : “my-website”,
“version” : “1.0”
“containers” : [
<<CONTAINER DEFINTIONS>>
]
}
Grouping
Versioning

Container Definition
•Names and identifies your image
•Includes default runtime attributes for your container
–Environment Variables
–Port Mappings
–Container entry point and commands
–Resource constraints
–Etc..
… No longer concerned over exact state

Example
{ “name” : “webServer”,
“image” : “nginx:latest”
“cpu” : 512,
“memory” : 128,
“portMappings” : [ { “containerPort” : 9443, “hostPort” : 443 }],
“links” : [“rails”],
“essential” : true
}

Container Instances

Cluster
•Provides a pool of resources for your Tasks
•A grouping of Container Instances
•Starts empty, dynamically scalable
… about underlying infrastructure not just a container

Container Instance
•An instance on which Tasks are scheduled
•Runs AMI with ECS Agent installed
•Registers into cluster on launch
… Forget how to make instance container runnable

•Amazon CloudWatch integration
•Amazon CloudWatch Logs integration
•AWS CloudFormation support
•Support for Tagging
•AWS Management Console
•Partner AMIs (including CoreOS)
