Choosing the right approach for your application ~ Abdurahman
Virtual Machines (VMs) and Containers have been around for a while now, but they're still not fully understood by many. In this post, we'll take a closer look at the differences between the two, and how to decide which is the right approach for you.

A Virtual machine essentially emulates and mimics the hardware and software of a computer. It allows you to run multiple operating systems on a single machine, which gives you the flexibility to run different software applications on each one. Each VM is fully isolated from the host machine, so if one VM crashes, it won't affect any of the others. This makes it a great option for running applications that are not compatible with the host operating system. Like running Windows or Linux on a MacOS host.
What are Containers?
Containers are similar to VMs in that they allow you to run multiple applications on a single machine, but they differ in a few key ways. While VMs virtualize the hardware and software of a computer, containers virtualize the operating system itself. This means that all the applications running in a container share the same operating system, but are isolated from one another, just like VMs. This makes containers more lightweight than VMs, allowing you to run more of them on a single machine.
Comparing VMs and Containers
The easiest way to understand the difference between VMs and containers is to think of them as separate houses or rooms for your business. VMs are like building an entirely new house for your business, with all the walls, windows, and furniture, just for your business. Containers, on the other hand, are like setting up a separate room inside your existing house just for your business, with everything you need to run it already in that room.
VMs are great for running applications that require an entire operating system, or when you need complete isolation from the host machine. However, they can be quite heavy, both in terms of the resources they consume and the management required to maintain them.
Containers, on the other hand, are much lighter and more efficient than VMs. They're great for running applications that share a common operating system, and they're much easier to set up and maintain. Because they use fewer resources, you can run more of them on a single machine, which can be a big cost-saver in the long run.
So, which one should I choose?
Choosing between VMs and containers depends on your specific needs. If you need complete isolation from the host machine and require multiple operating systems, VMs are the way to go. If you're looking to run lightweight applications and need to scale quickly, containers are the way to go.
When making your decision, consider factors such as cost, complexity, and scalability. If you're running a small business with limited resources, containers may be the best option for you. However, if you're running a large enterprise with complex software requirements, VMs may be a better fit.
In summary, both VMs and containers have their strengths and weaknesses. The choice between the two comes down to your specific needs. Understanding the differences between the two will help you make an informed decision and choose the best approach for your business.
