Every application has its own set of dependencies, which comprise both software and hardware. A virtual machine (VM) is a software or computing environment that allows developers to access an OS through a physical machine.
When compared to conventional technologies, Docker containers introduce a slew of new tags to the chart. In terms of technology, it’s particularly intriguing in circumstances where it aids cloud portability by allowing users to execute the same programs across many virtual environments.
Docker is the most widely used container technology, according to Statista research. Docker is an open platform for developers, and it’s a tool for isolating application dependencies by putting them into containers. Containers are more scalable and easier to utilize and deploy than earlier methods.
For many of the benefits of cloud architecture, the VM has been the go-to standard. But what if there was a lighter, more cost-effective, more scalable equivalent to a virtual machine? Docker is a container-based platform mainly used for developing distributed applications.
Docker Containers are reshaping the DevOps (developer operations) environment as a critical element in the DevOps toolbox. Docker Containers have a wide range of applications in the DevOps world. Using Docker Containers to run programs and then deploying them wherever (Cloud, on-premise, or any Linux flavor) is now a reality.
Virtual Machines enable considerable flexibility in heterogeneous environments, whereas Docker containers are focused on programs and their dependencies.
The only point of view that suggests which of the two should be picked is application design. Containers are ideal for applications requiring scalability and high availability; otherwise, virtual machines can be used.
However, Docker containers have certainly challenged the virtualization business. Containers in VM are easily said to be twice as resilient as one without the other. A hybrid strategy that uses both Docker and VM can be used on occasion.
On a physical host with a specific configuration and virtual machines with the same configuration, running the same amount of Docker Containers with the similar performance on both.
The answer to this is not certain. However, experts suggest that containers are gaining ground on virtual machines based on their configurations and benefits. Gartner, a well-known global research firm, predicts that by 2023, more than 50%of all businesses will be using Docker containers.
However, revenue for a serverless container like Docker will increase from $465.8 million in 2020 to $944 million in 2024, from a low base of $465.8 million in 2020.
