Why You Need Kubernetes for Your Application

If you want to compete with your competitors in your software application, you should consider adopting Kubernetes. While in the beginning, Kubernetes might be difficult, its benefits are endless compared to usual ways of deployment.

But first, what is Kubernetes?

Getting to Know Kubernetes

You want to make your delivery fast. You want to increase the number of users you are getting. More requests, more orders, more reliability, more robustness, more visibility, but guess what? Your infrastructure explodes! You can have more and more users coming on.

Another challenge that users encounter while building and deploying applications is how to make them more scalable.

Previously there used to be VMs for making large systems. You could initialize and initiate as many Virtual Machines as needed to handle the traffic and incoming requests.

However, Virtual Machines themselves have some challenges. They tend to be very bulky, costly, and require heavy hardware. This added to the overall costs of the business. You had to scale vertically, adding more resources to the system.

Containerization provided the remedy to this problem. Instead of installing the whole operating system, as in the case of VMs, containers execute in isolation and without any guest operating systems so that you do not have to install more and more resources.

Rather you can bring up more and more instances of a single application to handle the load. But as you increase more and more instances, how to manage them?

This is where Kubernetes comes to save you. Kubernetes is an open-source container orchestration platform that can help you to deploy the containerized application and bring the instances up and down as soon as possible.

Kubernetes is still being adopted by the businesses as mentioned here. Next, we will see how Kubernetes can deliver value to you.

What Kubernetes Can Do for You

Now that you know what Kubernetes is let’s see its impact. If you adopt Kubernetes for your application, you can expect the following benefits and value delivered in very little time:

Package Manager Availability

You are wondering if your solution will remain updated even in the future? Can you ensure that the libraries you are using will remain supported long way to cut your costs? Kubernetes have you covered via the Kubernetes registry. It has package manager availability and an online registry using Helm, similar to npm, ensuring your application is always supported.

More Secure Systems

Businesses are always prone to security threats. If not taken seriously, hackers or malicious users can find the loophole in your system, and you can end up having security breaches, loss of private or sensitive data, and worse, even financial loss! However, Kubernetes takes several approaches to solve this problem.

In Kubernetes, containers run in complete isolation. One container cannot interfere with other containers as long as you have defined how the containers talk to each other. Kubernetes also allows privileges so that unauthorized access is not given. This means that unrestricted access to storage, network, or critical areas is not permitted. Kubernetes uses minimal OS so that third-party libraries are not entertained. It has a built-in scanning of images facility and configuring security assess so that pods don’t have unrestricted access.

More Reliability

I cannot stress this enough. Imagine it’s Christmas time or Black Friday sale day. You have an online order delivery application. But as the number grows, your infrastructure explodes. You will end up losing orders and loyal customers. Kubernetes comes to your rescue by automatic scaling of the application. It can bring the services and nodes up and down as needed ensuring that your application works smoothly even during peak times.

Serving all the Customers

What if your application has nodes, but the traffic is not distributed evenly? Maybe your one geographical location is experiencing more traffic while the node at the other location is idle? Don’t worry. Kubernetes can automatically balance the traffic across the nodes so that your resources are evenly utilized without worrying about.

No more 50 Error

Things can go wrong. No matter how careful you are, there will always be a time when your application crashes thanks to a wrong deployment or failed test. But what if you can roll back as soon as the application crashes? Thanks to Kubernetes, this is an automated task and having its full support ensures your application never has downtime.

Self-Care and Health Checks

Kubernetes takes care of many housekeeping tasks. For example, there can be many unresponsive nodes. They might not be responding to the health check. Taking care of these nodes requires continuous and careful inspection. Kubernetes, on the other hand, can bring them up and down these nodes, restart them, and shut them down as needed so that you continually focus on what matters and let Kubernetes take care of infrastructure.
