Benefits Of Virtual Machines
- Isolation And Security: VMs provide strong isolation by running the applications on fully virtual Separate Operating Systems on a single physical machine. Isolation provides security for the applications in the environments.
- Versatility And Compatibility: VM comes with supporting various operating systems allowing for a wide range of applications to run on the same physical hardware. Its versatility makes it suitable for hosting multiple applications as per their specified environments.
- Snapshots And Rollbacks: Virtual machines facilitate taking snapshots and capturing the complete state of the VM at a specific point in time. It provides the facility for the users to roll back their known and required states in case of updates or any issues.
- Resource Optimization: Virtualization provides efficient allocation and utilization of resources providing dynamic configuration of hardware resources such as RAM, CPU, and Storage for specific amounts. Its flexibility enhances resource management and scalability in virtualized environments.
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?
