Kubernetes, often referred to as 'K8s' or 'kube', is an open source container orchestration platform. Its primary role is to automate software scaling, management, and deployment. Kubernetes is a Greek name that means helmsman or pilot. K8s, the abbreviation, indicates the eight letters between the 'K' and the 's'. Google open sourced the Kubernetes project in 2014.
Kubernetes combines over 15 years of Google's experience running production workloads at scale with best-of-breed ideas and practices from the community. It was donated to the Cloud Native Computing Foundation (CNCF) in 2015.
What is Kubernetes?
Kubernetes automates operational tasks of container management and includes built-in commands for deploying applications, scaling applications up and down to fit changing needs, monitoring applications, and making it easier to manage them.
Kubernetes architecture and operations
Containers serve as a portable and easily deployable form for encapsulating applications. Kubernetes, designed specifically for running containerised applications, has a distinctive architecture. In a Kubernetes cluster, there is a minimum of one control plane and one worker node (often a physical or virtual server). The control plane has dual responsibilities: exposing the Kubernetes API through the API server and overseeing the cluster's constituent nodes. It plays a key role in decision-making regarding cluster management and effectively responds to various cluster events.
At the core of Kubernetes is the concept of a pod, which represents the smallest execution unit for an application. Pods, comprising one or more containers, are executed on worker nodes.
Key components of the Kubernetes control plane and nodes
The control plane of Kubernetes comprises four essential components responsible for managing communications, node administration, and maintaining the cluster's state.

Helgrind: Detecting Synchronisation Issues in Multithreaded Programs
Let's explore how Helgrind can be used to detect and debug multithreading issues with the help of a multithreaded C program.
The Perfect Process of Booting a PC
Booting a PC seems as simple as eating a cake. But are you aware of all that goes on behind-the-scenes to bake a delicious cake or seamlessly boot a PC?
Exploring eBPF and its Integration with Kubernetes
eBPF, a game-changing technology that extends the capabilities of the Linux kernel, offers significant advantages for Kubernetes networking. It also greatly improves Kubernetes observability by capturing detailed telemetry data directly from the kernel. Read on to find out how its integration with Kubernetes has immense benefits.
Deploying Generative AI LLMs on Docker
Built on massive datasets, large language models or LLMS are closely associated with generative Al. Integrating these models with Docker has quite a few advantages.
Containerisation: The Cornerstone of Multi-Cloud and Hybrid Cloud Success
Open source containerisation software provides the flexibility, cost-effectiveness, and community support needed to build and manage complex multi-cloud and hybrid cloud environments. By leveraging this software, businesses can unlock the full potential of multicloud and hybrid cloud architectures while minimising vendor lock-in risks.

India's Leap in Supercomputing: Innovating for Tomorrow
As India strides towards self-sufficiency in supercomputing, embracing this evolution isn't just an option-it is pivotal for global competitiveness and technological leadership.
SageMath: A Quick Introduction to Cybersecurity
In the previous articles in this SageMath series, we delved into graph theory and explored its applications using SageMath. In this seventh article in the series, it is time to shift our focus to another crucial subfield of computer science: cybersecurity and cryptography.
Efficient Prompt Engineering: Getting the Right Answers
OpenAl's GPT-3 and GPT-4 are powerful tools that can generate human-like text, answer questions, and provide insights. However, the quality of these outputs depends heavily on how you frame the input, or prompt. Efficient prompt engineering ensures you get the right answers by designing inputs that guide the AI towards relevant, clear, and useful responses. Let's find out how to craft effective prompts with examples.
Analysing Linus Torvald's Critique of Docker
This article looks at Docker's security flaws, particularly its shared-kernel model, and contrasts it with traditional VMs for better isolation. It discusses Linus Torvalds' concerns, explores mitigation techniques, and proposes a roadmap for building a more secure containerisation platform using hardware-assisted virtualisation, true isolation, and a robust orchestration layer.
