Everything You Need to Know About Kubernetes Fundamentals
What Do We Know About Kubernetes?
Some people may refer to it as K8S or but Kubernetes is supposedly an open-source platform that transforms the operations for different types of Linux containers. It completely reduces the various types of manual-based processes dedicated to scaling and establishing containerized applications meaning that you can merge a couple of hosts running Kubernetes. Some of these groups can easily span different types of hosts all over the hybrid, private, and public clouds and due to this significant reason, Kubernetes is a fantastic platform for hosting cloud applications that demand quick scaling like data processing through Apache Kafka. It is also a great platform for providing Kubernetes certification training for interested candidates all over the world.
Developed and designed by some of the most renowned engineers at Google, Kubernetes has completely improved the Linux-based technology. Google being the early facilitator towards the container technology has publicly discussed the role of Kubernetes and containers through various aspects of technology. According to the RedHat, Google is responsible for the technology behind the Kubernetes and its cloud-based services, which is particularly the reason why it accumulates two billion container deployments per week. All of these deployments are functioned with the help of multiple platforms inside. Due to its extreme popularity, Kubernetes training and Kubernetes certification have gained wide importance in the modern world.
Years before Kubernetes came into existence; Borg was primarily used in the cloud-based technology. Kubernetes developed many years after Borg, and the technology that was used in its preparation become one of the key factors in modern day technology. Not many people are aware of this, but Red Hat Inc. was one of the first major organizations that embraced Kubernetes wholeheartedly. Partnering up with Google, before the inauguration of the technology, they had transformed into one of the leading contributors in the upstream project. In the year 2015, Google donated a major chunk of the Kubernetes project to the newly established Cloud Native Computing Foundation.
The Advantages and Business Value of Kubernetes in 2019
It wasn’t until the year 2013 when container technology started getting the much-needed popularity, thanks to the invention of Docker. The advantages of cost and effectiveness of containerization quickly gained wide popularity in the world of cloud computing. Soon after launching Docker, there has been a comprehensive range of many new and advanced container management platforms, dedicated to ending the complexity of operating container-based applications. Similarly, one of these platforms, also popular as an open source project of Kubernetes is now the standard in the cloud-based computing and container management.
The official website of the Dockers explains that a container image is a small-sized, light in weight, unequalled, and an easily executable chunk of software that contains the entire elements required to run: system tools, settings, libraries of the systems, runtime, and code. Containers, on the other hand, separate the software from its surroundings. For instance, differences between the staging of environments and development and facilitate to eliminate the possible threats between the teams managing various software on the same infrastructure. As a common practice, containers allow you to make the most effective use of the infrastructure to deploy and prepare applications quickly – a fantastic combination of the advantages. It’s no surprise that most of the SME, start-ups, and organizations are using the container-based technology at such a dramatic pace. According to research by 451, almost 250 percent hike in the cloud-based technology is expected to reach by the end of 2020.
If you are looking for ways to deploy a container, then look no further. A couple of months after Docker launched its popular technology, many new and old software organizations started adapting the technology for software development and various test process. However, when it comes to deploying and testing the containers in the production, you can easily end up with millions when employing the micro-services of the course of time. All of these containers should be supervised, deployed, and attached to the world outside including distribution, scheduling, and balancing the load. Suppose you are doing this on your own, and you would require a complete ops army or dev to achieve all of this. This is the part where the managing containers (container orchestration) or managing Kubernetes comes to the rescue.
Benefits of Kubernetes
Unchangeable
Kubernetes and containers inspire more and more developers to create distributed networks that work around the principles of an unchangeable infrastructure. An unchangeable or immutable infrastructure normally transforms as per the needs and requirements of the user and its restrictions. The most conventional way of doing these things with unchangeable infrastructure in the Kubernetes is by saying yes to the changes occurring on some of the most current objects like the incremental upgrades and alterations. When it comes to making changes in an application through a conventional manner, you should always log into a container used by the people or a VM to download the most updated software changes for your application. Delete the server permanently and restart it again to make use of the changes.
Velocity
The rate at which you continuously update your application and establish its new set of features for the users is called velocity in the Kubernetes-based technology. A couple of years ago, in order to make changes in software or when working on a new deployment, there would normally be a lot of downtime that would delay the deployment for a few hours. The developers mostly do it over the weekend or at midnight when the traffic was at a bare minimum. The most important concepts of Kubernetes that allow a high velocity are immutability, systems that can heal on their own, configurations and many more.
Configuration
Everything in the Kubernetes-based technology is regarded as a declarative configuration that constitutes the entire state of the system. This particular technology is an alternative to the conventional configuration method, where usually the state of the system is regulated by the implementation of a detailed set of instructions more than the declaration of the most wanted state of the system. Declarative configurations allow the user to narrate the entire state in which the system should be in and always be prone to the errors.
