Containerization is the process of packaging software code along with the necessary operating system (OS) libraries and dependencies into a single lightweight executable called a container. These containers can run consistently on any infrastructure, whether it’s in the cloud or on-premises.
Key benefits of containerization include:
- Portability: Containers allow developers to create an application once and deploy it on multiple operating systems. They run efficiently across different environments without needing to rewrite the program code.
- Scalability: Containers are lightweight and can be easily scaled up or down. Developers can add multiple containers for different applications on a single machine.
- Fault Tolerance: Containerized microservices operate in isolated user spaces, so a single faulty container doesn’t affect others. This increases application resilience and availability.
- Agility: Troubleshooting and updating containerized applications doesn’t interfere with the underlying OS or other services, enabling faster software release cycles.
