When Docker Containers Should Be Used

Docker containers are one of the most popular ways to deliver software. It can be used for everything from app testing to lowering infrastructure costs and many other applications. Docker, as any other technology, comes with limitations. This article will show you how to use Docker in the most effective ways, and also what not to do.
When to Use Docker
Pre-deployment app testing
Docker is a great tool for developers who are just starting to design an app. They can create and execute it quickly and easily for testing purposes. Docker allows developers to test an app on a local development computer without having to execute it on the host OS. This is possible by creating Docker container images and running them with Docker or another runtime.
Multi-cloud and hybrid cloud applications
Docker containers can be easily moved from one cloud environment to another because they are portable. Containers can be used to package your application once, and then move it to the cloud.
Apps based on microservices
Applications built on microservices architectures are well-suited for Docker containers. Because developers can use orchestration technologies such as Kubernetes and Docker Swarm to deploy each microservice in its own container, then link the containers together to create a complete application.
Cost efficiency
Because Docker containers are more efficient than virtual machines, they can be a great alternative for teams looking to save money on infrastructure. Redeploying VM-based apps with Docker will reduce their total resource consumption.
When Docker is Not Recommended
Security considerations
Containers that do not completely isolate applications from each other or the host OS are better for applications that require strict isolation.
GUI applications
Technically, it is possible to run graphical user interfaces within Docker containers. However, it is more difficult than running command line applications. Video games, for example, cannot be deployed using Docker.
Small-scale deployments
The complexity of managing Docker containers and container storage is too much for small-scale deployments.
