Introduction to Kubernetes
Kubernetes is an open-source system, for automating deployment, scaling, and management of containerized and microservices applications. But before starting with all the advanced level stuff, let's begin with the basics.
Kubernetes is an open-source project started by Google. It is a container orchestration engine and also an abstraction layer for managing full-stack operations of hosts and containers. Now it is under Cloud Native Computing Foundation.

How it all started?
Before 1990 80% of the applications were designed in the monolithic approach. We needed a specific operating system, hardware, and many other resources. It means every time we create a new application; we need to change or upgrade the OS or device. It was time-consuming and costly. Virtual machines solved this problem with the help of VM we were able to run multiple OS environments on a single computer that were isolated from each other. Many unpleasant incidents, like system crashing, reduced, and availability increased. Along with its advantages, there are some disadvantages too. VM is slow because these are dependent on the host hardware.
After VM, a new type of architecture came into the picture that was Microservices. Microservices are fast and more reliable. Its architecture allows dividing our application into independent services that can communicate with each other through APIs. App-building and maintenance became easy and smooth. But due to the complexity of microservices architecture, it is tough to test and monitor. Parallelly cloud-based PaaS - Platform as a service launched. PaaS is purely for web-based applications, and it provides full life support. It is effortless to deploy and maintain. But security risks and vendor dependencies are some cons along with it.

Containers were in the picture, along with the technologies with other technologies. The highlight is, it’s Operating System sharing capability. Every VM needs its Operating System whereas, multiple containers can share a single OS. The popularity of boxes steeped with the release of Docker. Docker is a tool designed to create, deploy, and run containers and container-based applications. For the orchestration of container tools like Docker, Kubernetes technology emerged.
Let us get some more clarity...
If you are still confused or are new to these technical terms like container or Kubernetes, let us clear basic with a simple example. Imagine a scenario - We are in the business of Bags. We have recently upgraded our business from a single local shop to eCommerce. Our team size is small, but we have hired a few developers to meet the IT requirements. With the increase in demand for our products, website traffic also increased. We need to add more features like online payment, adding multiple products to a shopping cart, etc. Along with it, we need to update our invoicing systems, temperature control monitoring, and other manufacturing equipment.
The developers suggested a technology ‘‘Kubernetes’’ that can provide us with a cost-optimized solution for all the problems. But the question is, what are Kubernetes and containers. The team of developers explains, sometimes our website runs on one developer’s platform but not on others. It is due to the difference in machine environments. Containers solve this problem. In the specification of boxes, we can specify the required setting, and they become the environment independently. It automatically makes them server independent too. Containers are more efficient, lightweight, and consume less computing resources. We can run several applications parallelly on the server. We need to manage hundreds of containers. I was like then when we will make the bags. They further explain to me that this is why we need Kubernetes. Without Kubernetes, we have to manage the containers manually, which can result in errors and can impact all our business. Kubernetes takes care of everything, deployment, management, and security. It can automatically rollout or rollback the containers as per the requirement. It is brilliant.

Top 6 Managed Kubernetes Platform Benefits for Businesses in 2023
- Cost-Optimization - Kubernetes is an open resource; it is available free for use. The basic concept of a container is resource sharing. Containers can share operating systems, hardware, and storage space. It helps in reducing the usage of hardware and data centres.
- Extreme Scaling - Due to its decoupled architecture support, Kubernetes provide a different kind of scaling for various purposes. For scaling of servers, you can use horizontal scaling, for the containers auto and manual scaling can be used, and for pods, you can use the replication controller.
- Enhanced Deployment Speed - You can continuously update your applications without any downtime. It supports features like immutable infrastructure, self-healing, and declarative configuration.
- High Availability - Kubernetes is designed to handle both the application and infrastructure. With its auto replacement feature, it can replace or heal any crashed pod. It can automatically balance the network load with its in-built load balancers.
- Portability - Kubernetes supports several platforms. You can run it on any public cloud, on-premises, and even multi-cloud. Due to its high flexibility, you can use it in any environment.
- Security - All the confidential information, for example, passwords, OAuth tokens, and SSH keys are stored securely on the Kubernetes secret object. You can easily replace the stored data without exposing it.

Top 5 reasons to switch to Managed Kubernetes Platform
- Lack of Skills - There is not enough talent in the market who can manage Kubernetes efficiently. If you are planning to implement Kubernetes, you need coder, but also the resource who can understand the operations, architectures, storage, and data flows. The average salary for K8S support is $116,000.
- Preeminent Security - 46% of users have identified it as a significant concern. Due to multiple traffic tracks, the risk factor increases. Every container has its surface due to that vulnerability increases. Data stealing from the boxes and unauthorized connections between the pods compromises the whole project.
- Complex Technology - Kubernetes is very complicated. It is challenging to manage the allocated resources. Over or under allocating resources may result in the pod crashing or not starting.
- Sustained Delivery - Continuous functioning of the Kubernetes is one of the critical factors, and it can be disturbed by many instances like network failure, low storage space, and pending updates or patchwork, etc.
- Tedious to Manage - It is tough to manage the Kubernetes. Improper management can lead to a broken control panel, DNS outage, failure of distributed systems, deployment failure, and many more.
