Explanation
Containers are a solution that offers isolation, portability, and scalability for software development and deployment. Containers are lightweight and self-contained units of software that package up the application code and all its dependencies, such as libraries, frameworks, and configuration files. Containers run on a container platform, such as Docker or Kubernetes, that provides the runtime environment and orchestration for the containers.
Containers offer isolation, as they run independently from each other and from the underlying host system.
Each container has its own namespace, filesystem, network, and resources, and does not interfere with other containers or processes. Containers also offer portability, as they can run on any system that supports the container platform, regardless of the hardware or operating system differences. Containers can be easily moved, copied, or deployed across different environments, such as development, testing, or production.
Containers also offer scalability, as they can be dynamically created, destroyed, or replicated to meet the changing demand for the application. Containers can also leverage the distributed computing power of clusters, which are groups of servers that work together to provide high availability and performance .
