Containerization is a operating system virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.[1] Such versatility makes it easier to manage hybrid or multi-clouds systems.
Usage
The containers are basically a fully functional and portable computing environment that provides a cloud or non-cloud computing environment surrounding the application and keeping it independent from other parallelly running environments.[2] Individually each container simulates a different software application and run isolated processes by bundling related configuration files, libraries and dependencies. But, collectively multiple containers share a common OS Kernel.[3]
Security issues
- Because of common OS, security threats can affect the whole containerized system.
- In containerized environments, security scanners generally protect the OS but not the application containers, which adds unwanted vulnerability.
