Even if you have an application that isn’t a perfect fit for containers, the consistent deployment pattern might be worth the time you need to set it up. It makes it easy to pass unchanging container images between computers, which simplifies development, testing, and deployment of new applications. When should I use Docker?Īs we’ve noted, Docker is a powerful tool. Understanding the weaknesses of Docker and how they relate to your use case is key to maximizing the return on your work to set up Docker. If your application requires two services to be running on the same machine at the same time, containers aren’t going to be a good fit. Unfortunately, you can’t work around some of Docker’s issues. If you’re concerned with Docker’s overall performance in production, Stackify’s Retrace is a powerful tool to help you identify the bottlenecks of your application. For instance, it’s possible to tune Docker to improve its performance if you can spend the time. You can work around or mitigate some of these issues. While it’s possible to run a GUI on Docker, it’s pretty convoluted and you’re going to have a tough time. Another downside to Docker is that if the application you need has a graphical user interface, you’re probably out of luck. Most applications don’t notice the difference in performance between virtual and dedicated environments.īut if you’re working in an environment where latency and speed are of the utmost importance, you’ll want to avoid Docker. Docker simply isn’t as fast as running an application directly on a dedicated server. All virtual environments come with a performance penalty. For starters, Docker containers run in virtualized environments. Like all technologies, there are downsides to using Docker. That’s why it’s been growing in popularity for the last few years and shows no signs of stopping. Docker has a pretty wide variety of strengths. If your application server and database server are running in different containers, a compromised application server can’t access the database server’s memory. No matter how badly you mess up, fixing your container is just a moment’s work.Ĭontainers can also have positive security benefits too. Because each container is built from an unchanging image, if you make a mistake, it’s trivial to revert your container back to the saved image.

Does your database server need a different version of a library than your message queue? Docker means you never have to worry about those two libraries conflicting.ĭocker also makes it really easy to experiment with new software libraries.
What’s more, you can separate the requirements for each type of server into their own container. Docker allows you to configure and run all three of those applications side-by-side. For instance, a complicated application might need a database, message queue, and application server to all run together.
If you’re building a complicated software application, you can use Docker containers in combination to build more complicated systems. That image is easily shared with other people on your local network or across the internet using Docker Hub.

What’s Docker good at?Īs noted, Docker is good at wrapping up all the packages and configuration you need to in order to run a software application into a portable container image. Because the Docker container works the same in every environment, it simplifies the deployment of a software application into a broader environment.

An image of a Docker container will run the same on any computer system you install it on, with no other configuration required.ĭocker is useful during the development, testing, and deployment phases of a software project. These containers are easily ported to other computers through Docker’s use of images, which are saved states of a container. Those containers have everything the application needs in order to run already-stored data on them. Docker is a technology first released in 2013 that runs applications inside virtual containers on a computer.
