How Kubernetes Is Changing The Cloud Computing Services?

30 May

Organizations have turned to using the Cloud due to the inherent benefits it offers such as portability, flexibility, agility, and cost control. The increasing reliance on multiclouds calls for a better way of managing the applications residing in the multicloud environments, which means organizations have to seek professional web development solutions. When IBM Containers, a containerization product aimed at simplifying the process of moving an app from the developer’s side to the IBM Cloud was introduced, it helped deal with the challenges experienced in the process by putting together code and the dependencies to come up with lightweight and efficient packages. It also helped developers run their app in any kind of environment.

Although the aim of IBM Containers was to simplify app-to-cloud movement, it however, had a shortcoming in its use because it made the Cloud environment management more complex. It is in that regard that Kubernetes was introduced to help ease those complexities and help simplify the management of Cloud applications through automation of deployment and scaling, as well as management of containerized applications.

Kubernetes is a considered a container orchestration tool available as an open source platform, which is crucial in ensuring the management of Cloud applications.

Clusters and Architecture of Kubernetes

The fundamentals of Kubernetes architecture are the clusters; they are the building block blocks. Each Kubernetes cluster comprises at least a single master node coupled with multiple worker nodes. The purpose of the master node is to control as well as monitor worker nodes alongside the entire Kubernetes resources within a cluster. It executes a scheduler service responsible for deciding the locations where applications are deployed or delivered depending on the requirements for the deployment and the capacity available.

On the other hand, worker node acts as a compute host responsible for deploying, running, and managing containerized applications. It uses tools to help manage containers like Docker. To effectively use Kubernetes in Cloud environments, you need to consider hiring a web development team.

Kubernetes Pods

In a cluster, pods are considered the smallest units to be deployed and Kubernetes builds pods that help host applications instances. Pods host one or more application containers as well as shared resources like networking information or storage information. They also house group containers, which have to be handled as one unit.

Kubernetes Deployments

To help manage stateless services running in Kubernetes clusters, Kubernetes deployments are used. A deployment is used to describe the preferred state of a pod while ensuring the actual state is in tandem with the desired state. When it comes to deployments, they help verify whether identical pod sets are operating and ungraded in a scalable manner to ensure rolling updates is executed without much downtime - that’s to say, zero downtime.

Kubernetes Security

While the capabilities of Kubernetes container orchestration ensure a developer automates app deployment as well as speed up the development process, at times, containerized apps can be vulnerable to attacks and exploits. The more the containers, the bigger the attack surface you have and the more vulnerability the attackers are able to exploit. A majority of the conventional security models or monitoring tools don’t address this problem because of the portable, flexible, and constantly changing nature of containers. For that reason, Kubernetes security has to form part of a deployment.

Kubernetes requires use of logging, monitoring, as well as alerting tools capable of accommodating the mutability and portability of Cloud environments. Your Kubernetes clusters need also allow audit logging in addition to monitoring of unwanted and strange API calls, especially authorization failures. When such failures occur, they often unearth a possible attacker trying to use stolen credentials.

Kubernetes Storage

In business-critical applications within an organization, there is demand for persistent storage. You find that containers use dynamic architecture made for workloads that tends to be short-lived or temporary. It is a big challenge for Kubernetes to reconcile the needs of organizations with containers’ stateless nature. A Kubernetes volume helps deal with the need for orchestrating and provisioning storage. The volume acts as directory accessible by the entire containers that run in a pod. The volume data is even conserved at time of restarting a container. There are many volume types supported by Kubernetes and pods are able to utilize multiple volumes at the same time. It is important that an organization understands the requirements of its apps in order to have proper storage planning and select the appropriate storage solution. The organization also needs to understand the kind and type of data to be stored, as well as how often such data is going to be accessed.

Kubernetes Integration

A big advantage of using Kubernetes is its ability to have continuous integration of systems in a frequent manner using the power of automation. It is possible to keep your systems current and identify issues if you use the continuous integration methodology in application development. You can also correct the issues early and minimize the development effort needed to achieve successful results. Kubernetes integration allows a developer to produce and deploy quality software products to end users who enjoy great software or app functionalities with fewer disruptions.

In short, these are some of the ways Kubernetes has changed the cloud-computing environment. Users can today find secure, reliable, and efficient Cloud services that are easier to use and migrate. With Kubernetes running within Cloud servers, programmers, developers, and engineers get a top-tier Cloud management tool that offers the infrastructure they need in handling huge projects in a faster way, for example, load testing of websites, creating staging environments, or moving online applications. The Kubernetes clusters work greatly in managing these tasks. Using custom web development services can help with your Kubernetes Cloud computing needs. Being able to deliver and join novel nodes within your cluster in a span of a minute greatly increases the service response time at time of high demand while also being able to optimize costs by spiraling down any unneeded capacity.
