Application Containerization Software
Containers are exploding onto the application development scene, especially when it comes to cloud computing. This is largely because portability has been a big chasm in this area, given the proprietary nature of some public clouds, and this technology abstracts applications into virtual containers that can be moved from cloud to cloud.
Virtualization
Containerization is defined as a form of operating system virtualization, through which applications are run in isolated user spaces called containers, all using the same shared operating system (OS). A container is essentially a fully packaged and portable computing environment.
Container as a Service or CaaS
Docker technology and its orchestration capabilities play the main role in creating Container as a Service or CaaS, while Infrastructure as a service (IaaS) provides raw assets with high flexibility and Platform as a service (PaaS) offers an optimized set of components or solutions that can be used for use cases where the development environment dictates the rules.
