Detailed Introduction to Kubernetes

Welcome to the digital world of Kubernetes in cloud computing services. The technological era demands work to be done with much accuracy and precision. Now let us proceed further and check and have a detailed introduction to Kubernetes

Definition of Kubernetes

Kubernetes commonly stylized as K8s is an open-source container orchestration system for automating computer application deployment, scaling, and management.

It was originally designed by Google and is now maintained by the Cloud Native Computing Foundation. It aims to provide a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. It works with a range of container tools, including Docker.

Many cloud services offer a Kubernetes-based platform or infrastructure as a service (PaaS or IaaS) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions.

Today in this blog we would be discussing and covering the below-mentioned points that are a part of the overall Kubernetes services.

• Need of Kubernetes
• Kubernetes Architecture
• How does Kubernetes work
• Advantages of Kubernetes
• Deployment of Kubernetes
• Conclusion

• NEED OF KUBERNETES
  It is that when there is a need to satisfy the business requirements and goals, there should be a system that should have the ability as well as stability to quickly develop the range of new services and applications. It is true that we can indeed start with the initial stage and that is a cloud development and that too in microservices containers. This is will therefore allow rapid development and deliver the work in a simpler way so as to optimize and transform the available applications.
  
  Further, the production applications extend different containers, and this is where we assist in the process of deployment of these containers throughout the work, and that too to different server hosts. It is that only Kubernetes provides you with the management and orchestration ability need to deploy containers.
  
  
• KUBERNETES ARCHITECTURE
  The client-server architecture is adopted by Kubernetes. We at Cloud Stack Group install Kubernetes on one single machine and node on a distinct system which is Linux. Here we have mentioned components of Kubernetes master machines that are as mentioned below.
  • Etcd: The work of Etcd comes into existence where it saves time for the configuration data that every node of the cluster uses. It is highly important and extremely accessible data that is being distributed amongst different set of nodes. It is accessible only when Kubernetes API Server.

• API Server:
  Kubernetes is considered as an API Server that provides every operation on the cluster through the API.  API Server executes an interface that indicates different Tools are ready to communicate.
  
  
  • Control Manager: It is the work of the control manger who is responsible as well as accountable to the collectors when the work is related to the controlling of the informaton and also with that the status of the information so as to execute the task. We consider the task as a daemon that executes in an interminable loop and accountable to collect and send information to the API Server.

• Scheduler: One of the important aspect and components of Kubernetes master is the steps and stages of scheduler. It is been considered as a service that is having its uniqueness and is accountable for sharing the workload.

• HOW DOES KUBERNETES WORK
  The Kubernetes deployment that we work on is called as the cluster. There are two parts in the Kubernetes clusters. (1) Control Panel (2) Node or Computer Systems.
  
  
  • Nodes:   Every Node contains an individual Linux environment and it can be a virtual and physical system. Every node implements pods, and they are built from containers.
    
    
  • Control Pane: Here comes the second option for the service which we all call as Control Pane. The core use and responsibility of control pane is that it is accountable for handling the required conditions of the cluster. These clusters are like or in the form of the application that we are running on and the images of the containers we use.

Computer systems implement the workloads and applications. The control pane of Kubernetes takes commands from the admin and transmits those commands to the computer systems.

The required state of Kubernetes cluster specifies which workloads or applications must be running, together with the images we use. From an infrastructure perspective, we can see slight changes in handling containers. We control the containers at a higher level and in a better way.

Working with Kubernetes includes configuring Kubernetes and specifying pods, containers, and nodes inside them. Kubernetes manage container orchestration.

• ADVANTAGES OF KUBERNETES

Now let us continue further and check on some of the advantages of Kubernetes services that play an important role in the integration of the Kubernetes Services. Well, with this said let us have a look at check on the advantages as shared below.

• Extraordinary Architecture:
  The architecture of Kubernetes is way much mature and easy to have the demonstration of architecture. It is the google engineers who prepare the design of Kubernetes architecture. This is all possible only with the help and assistance of the experience that the team has and with this it also assist in maintaining and burationilding container platforms.

• Abundant Feature of Collection and Application Support:
  Comparing with the rest of the container management systems(CMS). Kubernetes has an abundant feature set.
  
  
  • Open Source and Portable:
    The deployment of Kubernetes can be done on any platform. It is only possible with the help of Kubernetes that we can run the containers and that too in different cloud environments. As Kubernetes is compatible with different platforms, we can avoid cloud providers and infrastructure lock-in.
    
    
  • High Accessibility:
    Kubernetes can handle the accessibility of infrastructure and applications and makes it essential while deploying containers in Health Checks and Self Healing of the containerized applications.

• Develop to Develop:
  Containerisation has the ability to accelerate developing, testing, and deploying the software. Like other containerization platforms.

• DEPLOYMENT OF KUBERNETES
  In Kubernetes, Deployment gives assertive updates for ReplicaSets and Pods. The Deployment Controller alters the current state to the required state at a moderate rate. Through Deployments, we can create fresh ReplicaSets or we can remove available Deployments.
  
  
• Creating a Deployment using Kubectl
  Kubectl utilizes Kubernetes API for communicating with the cluster. Through the Kubectl commands, we can create the deployments that implement the applications on the Kubernetes cluster.

• Change the Deployment
  • Update
  • Rollback
  • Delete

• CONCLUSION:
  Cloud Stack Group is the prominent and leading cloud expert company that adhere to all the software and tools which are required for a successful implementation of Kubernetes sevices. Knowing the importance of the work and the service we are committed and bound to be with the customer and assist them for the work what they demand from us.
