When to Use: Docker Vs Virtual Machine
1. Use The Docker In The Following Cases
- Lightweight Isolation Is Sufficient: Docker is effective in situations where lightweight process isolation is sufficient. It is effective in usage with microservices architectures and for efficient containerized applications with minimal overhead.
- Fast Deployment And Scaling: Docker containers will start the applications quickly, making them suitable for dynamic environments that require rapid deployment and scaling.
- Consistent Development And Deployment: Docker provides consistency between development and deployment environments for applications. It ensures that applications behave in the same way across different stages of the development lifecycle.
2. Use The Virtual Machines In The Following Cases
- Fully Operating System Isolation Is Required: If your application needs complete isolation as separate operating systems, then Virtual Machines are the preferable choice. VM provides a stronger isolation, making it suitable for applications to run on diverse OS requirements.
- Legacy Applications And Compatability: VMs are preferable for hosting legacy type of applications that can’t be containerized easily. They support a wide range of Operating Systems making the applications compatible with specific OS versions and configurations.
- Resource-Intensive Workloads: VM can be used in scenarios where there is a need for intensive computations for workloads, we can go for VM for having granular control over the resource allocations and making them better suited for the cases.
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?
