Kubernetes: Orchestrating a High-Load Application Deployment With Containers

It is often said that containers are the future of application deployment. If that’s true, then why are some products still using VMs to do the job? Kubernetes offers companies a way to deploy applications on physical or virtual servers with high availability and scalability, while avoiding the common shortcomings of VMs (e.g., VM downtime, lock-in, and performance). For that reason, many large companies are moving towards adopting Kubernetes for their application deployment needs. If you’re thinking about hopping on the Kubernetes train, here’s what you need to know.

How Does It Work?

Kubernetes is an open source platform that orchestrates containers using a master-slave concept. This means that it works with any type of container (e.g., Docker, rkt, or bare metal) to ensure that the containers are running smoothly. Each container in your application is scheduled to run on a node of a cluster, with the nodes being automatically rescheduled if they go down. If you have more than one node in your cluster, then you can achieve load balancing and high availability using Kubernetes. In addition, Kubernetes provides a variety of features that can help you make your application run as efficiently as possible. Some of the features that can help you deploy and manage your applications include:

Autoscaling: With every container coming with a built-in scheduler, you won’t have to worry about over- or under-provisioning of resources. If your application starts to hit its peak load, then Kubernetes will adjust the number of nodes in your cluster to ensure that all of your containers have enough resources to run efficiently.

Configuration Management: With Kubernetes, you can easily scale up and down the number of nodes in your cluster as needed. This can be useful if you’re experiencing an increase or decrease in the number of concurrent users that are accessing your application at any given time.

Security: With containers being secure by design and run as part of a highly-controlled and secure cluster, you can be certain that your application code is safe from being compromised by outsiders. For added security, you can use Kubernetes to restrict which packages are available for your containers to use, limiting the attack surface that could be exploited by determined hackers.

Why Should I Adopt Kubernetes?

If you’re asking yourself why you should adopt Kubernetes, then the answer is quite simple: it’s the best tool for the job. As mentioned above, Kubernetes can effortlessly scale up and down the number of nodes in your cluster as needed, ensuring optimal performance and high availability. It can also help you secure your application by restricting the packages that your containers can use, and it can help you manage your configuration options with ease. With all of these great features, why would you not want to adopt Kubernetes for your application deployment needs?

The only downside to adopting Kubernetes is that it’s a fairly advanced tool that can require specific skills to setup and manage. However, with the right guidance and training, anyone can easily learn how to use Kubernetes to deploy and manage their applications. The best thing is that with every new release, Kubernetes makes the task of application deployment simpler and more enjoyable.

At the end of the day, your business needs and goals determine which type of application deployment solution you should go for. If you need to get your application up and running quickly with minimal effort, then you should opt for Docker. However, if you need a more robust and scalable application deployment solution, then you should look into adopting Kubernetes.
