Docker: The Smart Way to Containerize Your System

On April 30th, 2014, the computers at Los Angeles International Airport all crashed. The system's infrastructure was overwhelmed by a glitch in the En Route Automation Modernization (ERAM) air traffic control system. The bug caused the ERAM to run out of memory, and as a result, hundreds of flights were delayed or canceled.

While failures of this scope are rare, the infrastructure your technology runs on has an outsize impact on your business. Cost, organizational efficiency, and client trust all depend on the reliability of your IT systems. Simply put: when your applications load quickly and run smoothly, so does your business.

Over the last few years, the IT industry has embraced containerization as a reliable solution to speed application delivery. From startups working on the bleeding edge to large IT enterprises, companies of all sizes can use these virtual containers on top of their data center or cloud infrastructure to modularize their systems. Each container has its own CPU, memory, and network stack, but shares the same kernel as other containers on the same host. Containers can be “spun up” or dissolved based on how much demand the system receives at any given moment. When more memory is needed, more containers are instantaneously created.

Docker, an open source platform, is one of the most popular container technologies. Its innovation lies in image-based deployment, which provides a standard way of formatting applications to be placed in containers. This allows developers to use the same tools and workflows, regardless of the target operating system.

Why consider Docker for your business?

  • Using containers means you’ll need less hardware and less data center space. This saves money, both on the tools you use and the professionals who manage them.
  • Applications load fast while requiring less memory space. For the end user, applications on Docker load in fractions of a second, rather than minutes.
  • You can lower the risk for headaches when modernizing legacy software and making updates. Containers help modularize your system. This makes it easy to modify applications. Updates can be tested and launched quickly and problems can be rolled back without affecting other parts of your system.
