An open source tool to create, deploy, and run applications by using containers.
Containers are often regarded as the building blocks of cloud computing. Containers package up an application with everything it needs to run, meaning they’re readily portable — a feature that helps deliver the scalability and flexibility benefits of cloud.
Docker is the most popular tool used to create containers.
What is it?
Docker is the most widely used container technology today. Containers are a way to package up an application and its dependencies, which makes it readily portable.
This means that you’re organization can reap the scalability and flexibility benefits of cloud computing.
Docker enables your teams to develop an application in their testing environment and trust it will run seamlessly in production. A containerized application will run whether it’s in a private data center, the public cloud or even a developer’s laptop.
What’s in for you?
The portability of containers enables you to scale your applications reliably. That ability to scale enables you to have your infrastructure tailored to your actual requirements. So for instance, you could easily add more capacity ahead of a peak period, such as Black Friday. Once the event is over, you can scale down.
What are the trade offs?
Managing containers is tough — and that’s as true of Docker as it is of any container technology. You may need to make additional investments in container orchestration tools to get the most out of your use of Docker.
And as with any technology, it’s important to look at good practices. If your enterprise need additional training to deploy Docker effectively, you need to ensure that you’re using reputable trainers.
Docker is not the only provider of container technology. And the company that owns it, Docker Inc, may not always be successful as it is today. So as with any technology purchase decision, you may want to look at whether a change in ownership could introduce any risk to your business.
