5 Benefits Of Application Containerization
What, why and benefits of containerization
Hey there 👋 - Amrut here!
Happy Sunday to all working hard towards meta-skills mastery!
Containers have recently become a powerful tool for developers and IT teams.
With the ever-increasing complexity of modern applications and the need for fast and efficient deployment, containerization has become a game-changer for businesses of all sizes.
In today’s newsletter issue, I will explore the following:
What is containerization?
Benefits of containerization
Key takeaways
From improving scalability to reducing infrastructure costs, I’ll discuss how containers can modernize how you deploy and manage your applications.
Let’s dive in.
What is containerization?
Containerization is a technique of packaging an application with all its dependencies, configurations, and libraries into a single container image that can run consistently across various environments.
This allows developers to build, test, and deploy applications faster and more reliably without worrying about any dependencies or configuration issues.
It is often used in DevOps to streamline the software delivery process and improve the overall efficiency of software development.
Some of the popular tools used to containerize applications are:
Docker
Kubernetes
Rancher
Google Cloud Platform Container Engine (GKE)
Amazon Elastic Container Service (ECS)
Microsoft Azure Container Service (AKS)
5 Benefits of using containerization in your workflow
Here’s how containerization can benefit you or your team’s workflow:
1. Consistency
Using containers ensures that your applications run in the same environment, regardless of where they are deployed.
This consistency makes it easier to troubleshoot issues and reduces the likelihood of bugs caused by different environments.
For example. a developer can run an application on their laptop using a container and then deploy it to a production environment using the same container.
This ensures that the application will behave the same way in both environments, reducing the risk of unexpected behavior.
2. Scalability
Containers can be easily scaled up or down depending on demand.
This means you can quickly add or remove resources to match traffic spikes or dips without provisioning new virtual machines or physical servers.
For example, a popular e-commerce site can use containers to automatically scale its application during the holiday season when traffic is high.
This ensures that the site remains responsive and doesn't crash under the load.
3. Portability
Containers are designed to be portable, meaning they can run on any infrastructure that supports container runtime.
This allows you to move your applications between different environments or cloud providers without modifying the application code.
For instance, a company can develop an application using containers on its own infrastructure and then quickly move it to a cloud provider like AWS or Google Cloud without having to rewrite any code.
4. Efficiency
Containers use fewer resources than traditional virtual machines, which makes them more efficient.
This means you can run more containers on a single host, reducing infrastructure costs and making it easier to manage your applications.
For example. a company can use containers to run multiple applications on a single server, reducing the number of servers they need to maintain and lowering their overall infrastructure costs.
5. Isolation
Containers provide isolation between applications running on the same host, which improves security and reduces the risk of one application affecting another.
This is because containers use their own file system and network stack, separate from the host system.
For instance, a company can use containers to run multiple applications on the same server without worrying about one application accessing data or resources from another.
Key takeaways
When you are dealing with production bugs, having consistent environments with the correct packages, libraries, OS, and frameworks, becomes essential.
Sadly, much time and money are wasted if the developer workflow is not set up correctly to deploy applications faster.
Containerizing your application can significantly reduce costs, enable developers to test and deploy applications quickly with less effort, and significantly modernize legacy applications while lowering complexity and cost.
Think containerization when someone on your team says, “Oh, but the application works on my machine.”
