Cloud technology is transforming businesses and making them more scalable, flexible, and accessible. However, as you move more workloads to the cloud, data breaches and cyber threats become more prevalent. It’s one of the significant challenges, and your application must be resilient enough to withstand these threats. Fortunately, you can eliminate these concerns with a simple trick- containerization. In this blog, we’ll discuss how containerization works in the cloud, reduces the workload, and improves security.

What is containerization?

The containerization offers a solution to one of the most common limitations of a virtual machine- resource usage. With containerization, you can run multiple containers on a single machine with the ability to share the operating system kernel. This means that each container acts as a separate environment that hosts a particular application with specific dependencies, libraries, and binaries.

Containerization does not involve spinning up a whole new virtual machine for every application; instead, it bundles everything it needs into a single container that runs on a single machine.

Why does containerization enhance security in the cloud?

When you move your workloads to the cloud, the level of control you have over security dramatically decreases. However, containerization can help you keep you safe from cyber threats. With containerization, each container is a standalone environment that restricts communication with other containers, providing a natural way to isolate applications securely. This is because instead of traversing an array of dependencies that you are sharing across your applications, each application has only the bare minimum it needs to run, making it less of a target for attackers.

Moreover, containers do not create a potential target for attackers like virtual machines since they don’t have operating system middleware on top of an operating system. Thus, attackers will have a harder time exploiting security vulnerabilities of containerized applications.

How does containerization reduce workload and improve security in the cloud?

Containerization enhances security by keeping applications isolated from one another, so if one falls victim to a cyberattack, the others will be unaffected. Additionally, containerization’s architecture also enables a considerable reduction in workload, particularly in development and deployment. Traditional development models involve creating one application in an isolated environment, testing it, then moving it to production. However, this model is seldom efficient or scalable.

With containerization, you simply need to create an image of each application and its dependencies, test it locally, then deploy it directly to production, or any other environment, without any configuration concerns. This eliminates lots of manual configuration and infrastructure maintenance required for traditional development models.

Containerization is a powerful weapon in the fight against cyberattacks and workload issues in the cloud. The isolation of applications from each other is an important security feature that sets containerization apart from other virtualization models. Additionally, the reduced workload resulting from this approach makes it economical and easier to deploy and maintain applications. Containerization is the way to go for technologists looking to build and deploy secure, scalable, and efficient applications consistently.
