Containerized workloads and services are typically managed using the extensible open source Kubernetes platform. It makes it easy to deploy, automate, configure, and manage containers.

Containerizing applications using Kubernetes orchestration is a good way to reduce costs and errors in application development. When using this type of virtualization, applications run in special isolated containers that have their own processor, file system, memory, process space, and more. Containers can be transferred between OS distributions and clouds.

The Managed Kubernetes service will make the process even more convenient and easier. Companies that provide Managed Kubernetes https://itoutposts.com/managed-kubernetes-services/ take care of all the technical issues of working with Kubernetes components. We understand what kind of service it is, who suits it and what tasks it helps to solve.

A Brief History of Kubernetes

A popular solution for the rational use of server resources is virtualization. Using it, you can run multiple virtual machines on one server. At the same time, applications (and their data) are isolated from each other, which ensures security.

In the 2000s, containerization technology emerged. This is a virtualization technique in which applications are packaged into containers. Because of this, they can be transferred to different computing environments. Containers are completely isolated, so applications can't interact with each other. One way to use the technology is to rapidly scale up application instances at times of peak demand.

If you are dealing with hundreds of containers, you definitely need a tool to work with them. This is exactly what the Kubernetes open source platform exists for, which appeared in the public domain in 2014. It can scale applications, handle errors, provide deployment templates, and more.

A Kubernetes system is made up of clusters - sets of nodes of machines (both virtual and physical) that run containerized applications. The master node is called the "master" and runs processes that manage the state of the entire cluster.

Initially, the technology was created by Google "for itself" based on rich experience with high-load projects. In 2015, Google, together with the Linux Foundation, created a special fund Cloud Native Computing Foundation, to which Kubernetes was transferred. The company announced that all its services are built on containers and more than 2 billion deployments take place every week.

Benefits of Kubernetes in the real world Kubernetes is the best choice for tasks that need to scale quickly - in media streaming services. Kubernetes is used in many large projects. The infrastructure of the Wikimedia Foundation is built entirely on Kubernetes with a self-developed solution.

Advantages of technology:

• automating the deployment and removal of containers, as well as the distribution of their resources;
• detection of a container by DNS name or IP address and subsequent distribution of network traffic for stable operation;
• distribution of the specified amount of resources for each cluster;
• restarting and replacing containers that either do not work or do not meet the requirements;
• efficient storage and management of sensitive information. For example, passwords, OAuth tokens, and SSH keys.

Kubernetes as a managed service

Working with Kubernetes is a task for specialists of a fairly high level. In order to deploy and manage containers efficiently, they must constantly keep up-to-date with the state of technology. Managed Kubernetes is a good way to outsource these tasks to professionals with deep expertise in containerization and reduce potential issues.

Using the Managed Kubernetes service, you will receive ready-made and customized Kubernetes clusters for your tasks. The provider manages the wizard, provides tools for diagnosing the state and restoring the health of nodes, deploys virtual machines, updates clusters and nodes, backups, and other aspects of work.

The provider of such a service, as a rule, provides integrated components for various tasks, such as monitoring. In addition, it keeps TLS certificates up-to-date and changes parameters at your request.

When is Managed Kubernetes right for you?

Managed Kubernetes can make things easier for many companies, regardless of size.

• For a startup that does not have the resources for a separate expensive specialist, Managed Kubernetes is the best option. This service will allow you to focus on the product, and not on supporting the operation of clusters.
• For medium and large businesses, this is a good way to get a flexible infrastructure platform that can work in different environments (clouds and OS).

Managed Kubernetes is suitable for many tasks, both in the cloud and in the local environment.

• For almost any development. For example, mobile and web.
• To work with existing applications. For example, to transfer them to the cloud or create an infrastructure for machine learning.
• To create a really big infrastructure. For example, deploying and managing IoT devices.
• Kubernetes can also be used when developing applications using microservice architecture. In this case, you will be able to use one of the main advantages of microservices - independent development and updating of different application components. Using Kubernetes, you can quickly update or replace the desired part of the application, as well as allocate or reduce resources.

Thus, the Managed Kubernetes service will remove a significant number of technical issues from you, and you can start working on the functionality of the application. You get a flexible, stable and user-friendly solution that suits so many projects. At the same time, you do not spend money on the work of a team of highly paid specialists.

In addition, the provider can audit an existing solution with subsequent customization. This will be very useful if you are already using Kubernetes, but constantly encounter problems that cannot be solved in principle.
