What is Docker?

Docker is a software platform that allows you to build, test, and deploy applications quickly. Docker packages software into standardized units called containers that have everything the software needs to run including libraries, system tools, code, and runtime. Using Docker, you can quickly deploy and scale applications into any environment and know your code will run. Amazon ECS uses Docker images in task definitions to launch containers on EC2 instances in your clusters.
Running Docker on AWS provides developers and admins a highly reliable, low-cost way to build, ship, and run distributed applications at any scale. AWS supports both Docker licensing models: open source Docker Community Edition (CE) and subscription-based Docker Enterprise Edition (EE).
Docker is available on many different operating systems, including most modern Linux distributions, like Ubuntu, and even Mac OSX and Windows.
Docker Benefits
Ship More Software Faster
Docker users on average ship software 7x more frequently than non-Docker users. Docker enables developers to ship isolated services as often as needed by eliminating the headaches of software dependencies.
Improve Developer Productivity
Docker reduces the time spent setting up new environments or troubleshooting differences between environments.
Seamlessly Move Applications
Docker-based applications can be seamlessly moved from local development machines to production deployments on AWS.
Standardize Application Operations
Small containerized applications make it easy to deploy, identify issues, and roll back for remediation.
Docker Use Cases
Continuous Integration & Delivery
Accelerate application delivery by standardizing environments and removing conflicts between language stacks and versions.
Data Processing
Provide big data processing as a service. Package data and analytics packages into portable containers that can be executed by non-technical users
Containers as a Service
Build and ship distributed applications with content and infrastructure that is IT-managed and secured.
