When we talk about using cloud resources, two popular options are Virtual Machines (VMs) and Containers. Both help run applications separately, but they work in different ways. Let’s explore the main differences between these two technologies!
Virtual Machines (VMs): Each VM runs its own complete operating system using a program called a hypervisor. This means that every VM has everything it needs, including the application and the operating system. Because of this, VMs use more resources.
Containers: Containers are different. They share the same operating system but keep the application processes separate. This makes containers much lighter and more efficient since they only include the application and what it needs to run.
VMs: Since VMs run whole operating systems, they usually have more lag. This can slow things down because the hypervisor has to manage all the different operating systems.
Containers: Containers share the same operating system, so they can start up super fast—often in just milliseconds! They also use fewer resources, which helps them perform better and scale quickly.
VMs: VMs provide strong separation. If one VM has problems or is attacked, the other VMs on the same computer remain safe.
Containers: Containers do provide some separation, but not as well as VMs. If there’s a security issue with the main operating system, it could affect all the containers running on that system.
VMs: VMs are great for applications that need a full operating system, like older software used by businesses. For example, a financial program might run on a VM to ensure it stays secure and meets regulations.
Containers: Containers work best for modern applications, especially when you need to develop or update them quickly. For instance, a website might use containers for different parts, making it easy to update or scale them.
VMs: VMs are usually managed by hypervisors like VMware or Hyper-V, which focus on how resources are allocated and monitored.
Containers: Containers are managed with tools like Kubernetes. These tools make it easier to scale and recover applications that are spread out across many machines.
By knowing these key differences, you can choose the right technology for your cloud applications!
