Docker is a cross-platform program for building and deploying containerized software. It enables faster, more efficient development while reducing maintenance complexity in the long run.

As technology – especially enterprise technology- races forward at breakneck speed, it’s both a good and a bad time to be in the software business.

On one hand, there’s plenty of work for skilled developers. On the other, there may be too much work.

The enterprise software market is expected to grow 8.3% this year, and experts suggest it would grow faster if there were enough developers to meet the demand.

Faced with this pressure to produce more and better software, developers’ toolkits are expanding.

The priority now is technology that improves development speed and efficiency- tools like Docker.

What is Docker?

Docker is a cross-platform virtualization program used to create containers: lightweight, portable, self-contained environments where software runs independently of other software installed on the host machine.

Containers are largely isolated from each other and communicate through specific channels.

They contain their own application, tools, libraries and configuration files, but they’re still more lightweight than virtual machines.

Though container technology has been around since 2008, Docker’s release in late 2013 boosted their popularity. The program featured simple tooling that created an easy path for adoption.

Now, it’s a favorite DevOps tool which facilitates the work of developers and system administrators alike.

The Power of Containers

Containerization provides a workaround for some irritating development hurdles. For instance, running several different applications in a single environment causes complexity.

The individual components don’t always work well together, and managing updates gets complicated fast.

Containers solve these problems by separating applications into independent modules.

They feed into the enterprise-oriented microservice architecture style, letting developers work on different parts of an application simultaneously.

This increases the speed and efficiency of development while making applications that are easier to maintain and update.

Taken as a whole, it’s obvious why both software developers and IT teams like containers.

The technology enables the rapid, iterative development and testing cycles which lie at the core of Agile methodologies.

It also takes the burden of dependency management off system administrators, who can then focus on runtime tasks (such as logging, monitoring, lifecycle management and resource utilization).

Why Docker Is the Right Choice

Docker isn’t the only containerization software around, but it is the industry standard.

It’s a robust, easy-to-use API and ecosystem that makes using containers more approachable to developers and more enterprise-ready.

The program has an edge on previous solutions when it comes to portability and flexibility.

Using Docker simplifies the process of coordinating and chaining together container actions, and it can be done faster than on virtual machines.

Docker removes dependencies and allows code to interact with the container instead of the server (Docker handles server interactions).

Plus, there’s a large repository of images available:

Getting up to speed with Docker doesn’t take long. The documentation is thorough, and there are plenty of tutorials online for self-taught developers.

Docker In Action: The Financial Times

The Financial Times is a London newspaper founded in 1888. Their online portal, FT.com, provides current business and economic news to an international audience.

The media outlet was one of the earlier adopters of Docker back in 2015. Docker containers helped cut their server costs by 80%.

Additionally, they were able to increase their productivity from 12 releases per year to 2,200.

Looking Forward

Last year, the median container density per host rose 50% from the previous year.

In fact, the application container market is poised to explode over the next five years.  Experts predict that annual revenue will quadruple, rising from $749 million in 2016 to over $3.4 billion by 2021.

Docker specifically still leads the pack despite the niche popularity of emerging tools.

83% of developers use Docker. CoreOS trails well behind it at 12% with Mesos Containerizer at 4%.

Overall, Docker Containers is a highly enterprise-oriented solution.

Other tools are emerging to add functionality (like container orchestration platform Kubernetes), so there’s no reason it shouldn’t continue growing in popularity.
