Containerization (computing)
Containerization is an operating system-level virtualization or application-level 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]
Usage
The containers are basically a fully functional and portable 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[3] by bundling related configuration files, libraries and dependencies.[4] But, collectively multiple containers share a common OS Kernel.[5]
In recent times, the containerization technology has been widely adopted by Amazon Web Services, Microsoft Azure and Google Cloud Platform.[6]
Types of containers
- OS containers
- Apps containers
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.
