Container is a unit of software that provides a standard way to package up application code and all its dependencies and configurations in a single unit so the application runs quickly and reliably from one computing environment to another.
Container can help take Development, Deployment and Shipment of applications to next level regardless of the environment and ease out the whole complex process.
How Containers actually work?
In brief if we explain, this can be explained in four steps:
Step 1: Build a container image : Package the application code, configuations and its dependencies inside the image.
Step 2: Automate the testing and deployment: Pre-code the stuff up.
Step 3: Run anywhere: Run the container anywhere regardless of the environment.
Step 4: Scale Quickly: Containers do not take much time start and terminate so scalability an be achieved hassle-free.
Where can we use Containers?
- Cloud Migrations
- Machine Learning
- Batch Processing etc.
