Kubernetes can help you with containerization and create a more modular infrastructure. But, if you want to achieve better scalability and flexibility, then it’s time to move your Kubernetes cluster to the cloud. The best part – Kubernetes is cloud agnostic, which means you can move the clusters to any cloud provider seamlessly and they would still run in the same way.
Why the need for cloud deployments
The biggest need of the hour is for developers to write applications that can run seamlessly across different operating environments including public and private cloud, as well as on-premises servers. Traditionally, both applications and tooling which supports them were closely connected to the underlying infrastructure. Though it was not only costly, applications also became dependent on environments in several ways including adherence to cloud constructs, dealing with performance issues because of network architecture, and dependency on back-end storage system.
While Platform as a Service (PaaS) may seem like an option but the costs that are associated with programming in it and setting up application frameworks is the reason most development teams stay away from it.
Along comes Kubernetes which does not need any infrastructure lock-in and provides core container abilities through features like pods, services, and dockers.
Kubernetes is cloud agnostic
With Kubernetes by your side, you can run your cluster on any cloud including Google Cloud, AWS, Microsoft’s Azure, and Rackspace. No matter where you move the cluster, it will run more or less the same with no glitches or performance issues. The biggest advantage is of course that Kubernetes potentially up-ends the idea of running everything on the same cloud.
Though we are still not at a point where we can have a multi-cloud Kubernetes automation, it is possible to have a multi-cloud federation at moderate costs by manipulating a few basic parameters manually.
Ideally, you should be easily able to interact with all the clusters, no matter what cloud they are stored in and keep the whole deployment exactly the same. Static configurations are usually the way to go when you are just starting out Kubernetes since you can easily make basic modifications like changing a parameter or increasing the number of replica sets.
With cloud deployment, you can easily templatize Kubernetes and have a fixed set of configuration parameters for quick deployment.
Advantages of cloud agnostic Kubernetes deployment
With Kubernetes, you finally get a portable abstraction that can work in just about any cloud infrastructure. It provides a single platform to handle everything. The whole idea with Kubernetes is to create a platform that can handle all the messy bits in the background and give you a predictable and consistent layer to build on top of it.
One of the biggest advantages of cloud deployment of Kubernetes is that developers get a single layer to build. Once you make sure the layer has all the specifications your application needs to run, it will always run. This means that you no longer have to worry about how the infrastructure is and if it can fulfill the application requirements.
With Kubernetes, you get support from an entire community that is always passionately working towards releasing new projects and features to make it even more useful. For instance, a dashboard was recently introduced with a UI that makes it easy to check resource utilization, and there is also a new cluster federation which is under development.
With a single platform to build your application, Kubernetes gives you the opportunity to create a new cloud platform. By deploying Kubernetes on the cloud, you are able to achieve a more universal, community-driven, and open infrastructure which doesn’t depend on the cloud provider that you use.
Why development teams should use Kubernetes without considering the cloud provider
As we mentioned above, the multi-cloud trend is gaining popularity among development teams all around the world. For enterprise projects, multi-cloud doesn’t just prove to be more affordable but also more functional as well.
Since you package all applications into containers with Kubernetes, they become more versatile and portable. Not to mention, moving containers between cloud is much more easier. With more portability, you get the flexibility to get out of the vendor lock-in jail, and you can choose multiple cloud providers according to your requirements and budget as well.
With container-based applications, another useful step is to break the monolithic core infrastructure into a microservice infrastructure. That is because microservice applications are less dependent on the underlying infrastructure, making it perfect for them for Kubernetes cloud deployment.
Migrating Kubernetes clusters to the cloud may seem like a task, but if you have chosen the right tools, then the entire process will be smooth and seamless. Not to mention, once you have moved to the cloud, you will be able to scale much more easily.
