What is kubernetes & What are there benefits?
Kubernetes is an open-source container orchestration platform that allows cloud applications to run on an elastic web server infrastructure. Kubernetes can be used to outsource data centres to public cloud service providers or for large-scale web hosting. Website and mobile applications, complicated customized code can be deployed on commodity hardware using Kubernetes to save money on web server provisioning with public cloud hosts and help accelerate software development.
Kubernetes has the ability to automatically provision web servers based on the amount of web traffic in production. Web server hardware can be located in a variety of data centres, on a multitude of platforms, and through a variety of hosting providers. Kubernetes grows web servers in response to software application demand, then downscales web server instances during downtimes. For web traffic routing to web servers in operations, Kubernetes also provides robust load balancing features.
What are the benefits of Kubernetes?
1. Improves productivity
Kubernetes, when properly integrated into development workflows, can result in significant productivity increases. The vast Kubernetes ecosystem, which is best illustrated by the CNCF Landscape, makes it easier and more efficient to use Kubernetes while minimizing the negative impact of its general complexity. You can obtain solutions that you could never build yourself by depending on some current technologies designed specifically and explicitly for cloud-native apps.
For example, An organisation recently integrated DevSpace, an open-source development tool that allows you to build up and standardise the deployment and testing workflow for every developer on your team, to CNCF. Other tools, such as Drone, make it easier to develop Kubernetes CI/CD pipelines, and tools like Prometheus make monitoring easier than ever. This multitude of tools substantially reduces release cycles, professionalizes engineering procedures, and ultimately enhances software quality from development to production. Of course, having such a diverse range of technologies allows you to tailor everything to your own requirements. Furthermore, the majority of the tools in the K8s ecosystem are open-source and thus free to use.
2. Kubernetes and a cloud-native tech stack attracts talent
Many software developers aspire to work for firms that employ cutting-edge technology, and Kubernetes is unquestionably one of them. Your technological stack and processes will be very enticing to potential applicants when combined with an efficient workflow and other cloud-native solutions. Working on something new can also be incredibly stimulating for your present staff, which enhances overall satisfaction in your development teams and can even reduce employee turnover in the long run. This Kubernetes benefit is often ignored, but given the scarcity of tech talent, it might be a significant benefit to your company.
3. A future proof solution
If you choose Kubernetes, you can be quite certain that this solution will be viable for many years to come for various reasons:
Kubernetes is supported by all major cloud vendors.
In terms of acceptance, cloud vendor support, and ecosystems, alternative container orchestration technologies lag significantly behind k8s. Even companies that were previously focused on competing technologies are now endorsing Kubernetes: Docker is now offering Docker Kubernetes Service rather than just Docker Swarm solutions, and Mesosphere has changed its name to D2IQ to be more open for Kubernetes rather than purely focused on Apache Mesos.
And, of course, the Kubernetes ecosystem is rapidly expanding, with new products covering various needs on top of the Kubernetes platform being introduced on a daily basis.
Kubernetes is also future-proof from an individual standpoint: if you expect your user base to grow to a massive size, you can rest assured that Kubernetes will be able to handle it because it was designed to support large, distributed systems and was developed by Google engineers with experience building scalable platforms like Borg. The same is true if your app expands and becomes more complicated. Microservice architectures are frequently used in this scenario, and Kubernetes is definitely the solution of choice right now.Finally, if you need to move cloud vendors for some reason, such as moving from Amazon Web Services (AWS) to Microsoft Azure, you can readily find a very similar Kubernetes service from another provider, and Kubernetes makes such a switch very smooth, avoiding vendor lock-in.
4. Make your application run more stable
Kubernetes can help you ensure that your application is up and running in a very reliable manner. For example, it enables rolling updates to change your software without causing disruption. It is also possible to set up Kubernetes in such a way that it facilitates high availability applications, and if you use key vendors' public cloud services, you may be confident of achieving very high uptime. (Of course, though, other technologies and infrastructures can also be used, but generally far more effort is required.)
5. Is cheaper than its alternatives
Another benefit of k8s is that it is sometimes less expensive than other options (depending on your application). Because the platform has some general computing requirements, very small apps are frequently more expensive. However, when your computing resource requirements grow, these basic infrastructure requirements become less significant in the final cost calculation. Other considerations become more relevant in such situations. Kubernetes, for example, may auto-scale based on your application's requirements as well as the incoming traffic and load it processes.That means Kubernetes can scale up your apps and required resources during peak times all while scaling down your infrastructure during down times of the year, week, or even hours of the day. If there isn't much going on, you'll pay less. In the end, this results in high utilisation and prevents you from paying for resources you don't require.
The relatively new idea of "nodeless Kubernetes," which includes solutions like Virtual Kubelet and elotl, offers even more potential for infrastructure cost savings.
Overall, Kubernetes can be less expensive in some cases and more expensive in others, and the cost of running it can always be reduced. You must examine it for your individual application and compare the various providers for your requirements (however, for the choice of your cloud provider, more factors than just cost will usually play a role).
