Similarities Between Docker And VM
The following are the main similarities between Docker and a Virtual Machine:
- Isolation Environments: Both Docker and Virtual Machines provide some extent of isolation for the applications. Docker achieves isolation through containerization on isolating the processes whereas VM achieves full virtualizing as two entirely separate operating systems.
- Portability Of Applications: Portability of applications can be possible on both the docker and virtual machines to run the applications consistently across various different platforms. Docker provides docker images and VM provides encapsulating the entire virtualized OS, enabling easy migration between various platforms.
- Snapshot And Versioning: Snapshot and Versioning are supported in both platforms allowing users to capture the current state of an application at a specific point in time. It is useful for creating backups, testing, and versioning and provides an effective way of reverting to a specific known state.
- Resource Management: Both Technologies provide an efficient resource management. Both facilitate with allocation of specific resources such as CPU, memory and storage ensuring that applications run with necessary resources without any interference from each other.
Virtualisation with Docker Containers
In a software-driven world where omnipresence and ease of deployment with minimum overheads are the major requirements, the cloud promptly takes its place in every picture. Containers are creating their mark in this vast expanse of cloud space with the world’s top technology and IT establishments relying on the concept for their infrastructural necessities.
Tech giants like Facebook, Google, and Microsoft use containers in their streamlined processes to facilitate a secure and easy deployment into the cloud production environments. This deployment with containers offers a technique, that abstracts the application from the run-time environment offered by virtualization. The two core concepts to be explored here are:
- How are containers built on the virtualization technique?
- How do they offer an alternative to virtual machines?
