What are the reasons and when to use Kubernetes?

Kubernetes handles the traffic and allocates resources to the service, starting with a set of Docker-created containers.

By doing this, it helps to make managing infrastructure for service-oriented applications simpler and more efficient. With the latest CI/CD tools, Kubernetes can scale these applications without requiring a major engineering project.

We can look at some of these Kubernetes applications more carefully.

  1. KUBERNETES FOR CONTAINER ORCHESTRATION

Containers, when used in isolation, can be a great solution, offering an easy method to organize and distribute your services using a simple creation process. This allows for benefits such as efficient use of resources, mutability, and process isolation.

But, when running your project in production, it’s likely that you’ll be dealing with dozens or hundreds of containers, particularly during the course of. If the work is carried out manually, you’ll likely require a dedicated team of container managers to connect, update and manage the containers.

Just running the containers isn’t enough. Additionally, you’ll need to be able to do these things:

  • Scale up or down to accommodate the changes in the demand
  • Incorporate and orchestrate a variety of components of modular construction
  • Connect across the clusters
  • Make sure your containers are fault-tolerant

It’s normal to believe that containers can handle everything without the necessity of a platform such as Kubernetes. However, the truth is that containers operate at a lower level of organization. To gain the advantages of a system constructed with containers, it’s essential to utilize tools for orchestrating containers, such as Kubernetes, which are applications that operate on top of containers and can manage them.

  1. KUBERNETES FOR MICROSERVICES MANAGEMENT

The idea of microservices is not an original concept. Software engineers have been breaking large-scale applications into components that can be reused for a long time. Microservices have many advantages, from a higher amount of resilience to quicker and more adaptable models to deploy to simpler automated tests.

Microservices allow decision-makers to select the most appropriate tool for the job at hand. A part of your app could benefit from the increased productivity of high-level languages like PHP, While another part could benefit more by using a fast language such as Go.

However, how do Kubernetes integrate into the microservices model? Yes, breaking down your application’s large scale into smaller, less tightly connected microservices will give greater flexibility and freedom of action. It’s nevertheless necessary for your team to collaborate and make use of the infrastructure these different components rely on to function.

It’s important to determine how many resources the parts will require and how the requirements shift with the load. It is necessary to create parts of your infrastructure for the various microservices you have and limit the usage of resources following that.

This is where Kubernetes can assist by providing a standard framework that offers an overview of your infrastructure’s architecture, allowing users to analyze and resolve shared resources and issues. If you’re thinking of creating an architecture that relies on microservices, Kubernetes can be massively useful.

  1. KUBERNETES FOR CLOUD ENVIRONMENT MANAGEMENT

It’s not surprising that container technology and software that manage them are becoming increasingly popular since many modern companies are moving towards microservice-based systems. Microservices allow for the simple division of an application into separate pieces, which are divided into containers that run on separate cloud environments. This lets you choose the right host for your requirements for each scenario.

Kubernetes is made to be deployed wherever it is possible to use it in an individual cloud or even a hybrid cloud, a public cloud. This lets you connect to your users regardless of where they are and with enhanced security in addition to being a bonus. Kubernetes can help you get around the potential issue of locking in your vendor’.

Why Not Use Kubernetes

Although Kubernetes is capable and versatile, it’s not the best tool for every situation or project. Be aware that Kubernetes was designed to address the potential for a specific set of problems and difficulties. If you’re not currently experiencing those problems, It’s quite possible that Kubernetes could prove to be more difficult than it is helpful. If you want to learn Kubernetes, then consider taking Kubernetes Certification.

If your project appears to be at a stage where deployment and scaling require the use of a dedicated resource, orchestration begins to become an option.

The notions of orchestration and automation work hand in hand. Automation helps businesses increase efficiency and reduce human interaction with electronic systems. When software handles these interactions, we see a decrease in errors and expenses.

In general, the term “automation” refers to automating a specific job. However, orchestration refers to the automated execution of an entire process or workflow comprising many steps and several systems. In the beginning, you incorporate automation into your workflow. When the complexity increases to unmanageable, the orchestration will take over, controlling the process and making them work together.

Kubernetes does not make sense for: not the right option for:

  1. Small-scale or simple projects because it’s expensive and complicated.
  2. Projects with a small number of users, a simple design with no plan to increase the number of users.
  3. Developing an MVP version isn’t bad, but starting with something simpler and less complicated, such as Docker Swarm, is best. Once you’ve crafted the way your app will run, it’s time to consider thinking about changing to Kubernetes
