What is Docker?
Docker is an open-source platform used to build, test, and deploy applications. The tool packs softwares into standardized units, known as containers, which contain system tools, codes, libraries, etc., needed to run applications.
Businesses use Docker to take care of repetitive, tedious configuration activities throughout the development lifecycle. In addition, the platform helps with fast, easy, and portable application development for cloud and desktop tools.
It comes with UIs, APIs, CLIs, and security integrated to work for the complete software delivery process.
Why use Docker?
Using Docker for the following reasons is enough to convince solo developers and businesses on how they can use robust, off-the-shelf tools with complete control.
Ship code quickly
The platform allows users to ship isolated services 7x more frequently than non-Docker users.
Standardize application operations
Containerized applications are small, easy to deploy, find issues, and reverse for mediation purposes.
Shift code easily
Users can easily move Docker-handled softwares from local development machines to the production environment on AWS.
By running additional code on each server, users enjoy better utilization of resources and save money.
Impact on the development ecosystem
Docker is helping professional app developers with the following benefits impacting the entire development ecosystem.
Docker is for ‘everyone’
The tool aims to get in everyone’s hands by backing its claim through easy-to-learn dynamics and simplicity in running commands on any project.
Configuring your environment for various software versions on the same machine was a tedious job. Docker allows developers to create an isolated environment, Docker container, for every app version.
Quick development & deployment
Docker makes each deployment easy due to lightweight images and Continuous Integration and Continuous Delivery (CI/CD) workflows.
You can create applications not dependent on any operating system, and running a Docker container on macOS, Linux, and ARM platforms is mostly the same.
Running more workloads on the same machine
Scalability and flexibility are one of the main features of containerization technology. As each container is stuffed with its configurations and technical assets, users can run multiple instances of the same containers.
Better security protocols
Docker-based applications are, by default, far more secure than any other typical app. Even a container cannot penetrate another container and its assets without having authorized access. In addition, users can also add multiple layers of security.
Ship code anytime, anywhere
App migration is always a tremendous task requiring considerable configuration and setup investment. However, you can simply install Docker on your preferred machine, execute commands and get the project running in no time.
Seamless dependency management
Previously, when a project ran on a different machine, teams needed to set up all the dependencies, including configurations, libraries, and databases or cache. Docker enables you to run parallel projects through a dependency management feature. In doing so, each project can be isolated alongside all the dependencies in a single container.
With all the reasons and benefits stated above, the rise of containers is shifting the way applications are developed, from monolithic stacks to microservices.
It doesn’t matter if there is a digital marketing agency, an online retail business, or any other business needing software development, application developers opt for a more minimalistic approach, speeding up feature releases, shortened development cycles, and bug fixes to create an engaging experience.
