10 Little-Known Facts About Kubernetes That Will Take Your Cloud-Native Journey to the Next Level

Kubernetes, a popular container orchestration system, has been leading the cloud-native revolution in the tech world. Since its inception in 2015, Kubernetes has gained massive traction and has become a go-to tool for enterprises globally. Even though Kubernetes has been making waves in the tech industry, there are several little-known facts about the platform that can significantly boost your cloud-native journey.

1. Kubernetes Origins

Not many know that Kubernetes was originally developed by Google engineers as a replacement for their in-house cluster management system, known as Borg (circa 2005). The project was open-sourced in 2014, and since then, it has been one of the leading technologies in the cloud-native revolution.

2. Kubernetes Segments

Kubernetes is typically categorized into three main segments or control planes: the control plane, compute nodes, and etcd. The control plane is responsible for centralizing control and coordination of cluster operations, while the compute nodes are where your workload gets executed. On the other hand, etcd is a distributed key-value database that stores all the cluster information and state.

3. Resource Allocation

Kubernetes allows for efficient resource allocation by dividing workloads and deployments across multiple pods in a cluster. Each pod runs on a worker node, and with a handful of features like resource requests, limits, and horizontal pod autoscaling, an application's available resources can be intelligently allocated for optimal performance.

4. NameOrigin

Why is Kubernetes called Kubernetes? The name originates from the Greek word 'kubernetes,' meaning 'helmsman' or 'pilot.' The creators wanted to choose a name that conveyed the notion of navigating complexity and managing intricate systems, which is the very essence of Kubernetes.

5. Deployments

Kubernetes deployments are precise and well-controlled, ensuring consistent application deployments across environments. Deployments allow for flexible configuration, routing, and health checks, which can greatly simplify the DevOps process and ensure increased reliability.

6. Rolling Updates

Rolling updates in Kubernetes enable administrators to deploy new application versions without causing downtime. Rolling updates are automated, allowing administrators to update or roll back deployments without manually managing containers.

7. Kubernetes Networking

Networking is a crucial aspect of any application, and Kubernetes isn't an exception. Kubernetes simplifies networking with features like service discovery, load-balancing, and network policies. The network policies, in particular, allow for controlling traffic flow between pods and clusters.

8. Namespaces

Name-spaces in Kubernetes play a significant role in ensuring isolation and segregation between different applications or teams. With namespaces, you can separate different system resources and access control information, ensuring better cluster management and increasing overall efficiency.

9. Kubernetes Security Best Practices

Securing clusters is of paramount importance for any organization. Kubernetes, bless its heart, provides extensive support for security, with a multitude of security best practices. These include features like secrets management, role-based access control, and network policies, to name a few.

10. Kubernetes Choice of Businesses

While Kubernetes may not be the best-suited tool for every business, it has become a go-to solution for many leading businesses globally. Major names like Cpluz Logo
