Kubernetes Architecture: Breaking It Down

Kubernetes operates using a layered architecture with components like Kubernetes Cluster, Master Node, and Worker Nodes collaborating to automate deployment and management of containerized applications.
The Kubernetes Cluster consists of Master Nodes governing operations and Worker Nodes executing workloads, ensuring high availability and scalability.
The Master Node acts as the control plane, scheduling tasks, maintaining the desired state, and responding to changes, with components like API Server, Controller Manager, Scheduler, and etcd.
Worker Nodes execute workloads by running Pods, which contain containers, with components like Kubelet, Container Runtime, Kube Proxy, and Pods ensuring efficient resource utilization and fault tolerance.
Understanding Kubernetes architecture is essential for deploying scalable applications, as it separates concerns between the Master Node and Worker Nodes, streamlining operations and ensuring efficient running of containerized applications.

Kubernetes: The Backbone of Modern Cloud-Native Applications

Kubernetes automates deployment, scaling, and management of containerized applications, ensuring efficiency and seamless operations in the world of cloud computing.
Manual container management poses challenges such as time-consuming scaling, downtime due to crashes, and complex traffic distribution that make it inefficient.
AWS's Elastic Kubernetes Service (EKS) offers automation benefits without cloud provider lock-in, allowing businesses to seamlessly move between providers for unmatched flexibility.
Kubernetes is an open-source project, not a paid service or a cloud provider. It collaborates with Docker to orchestrate containers across machines, providing high availability and fault tolerance.

🔥Virtual cluster inside a K8S cluster 🔥

Namespaces in Kubernetes create virtual clusters inside the physical cluster, providing logical boundaries and isolating resources.
Namespaces allow teams/projects to use the same cluster without interfering with each other, group resources logically, and manage permissions and access controls.
Namespaces are applied to namespaced objects like Pods, Services, configMaps & Secrets, and can set CPU & Memory limits.
Default Namespaces in Kubernetes include Default, Kube-system, Kube-public, and Kube-node-lease, each serving specific functions within the cluster.

Node.js Performance Optimization : Cluster Module

In 2025, many developers are still running powerful multi-core servers with Node.js applications on just a single CPU core due to overlooking Node's clustering capabilities.
Node.js uses a single-threaded event loop model, limiting applications to utilize only one CPU core, leading to inefficient resource utilization on multi-core servers.
The Node.js cluster module allows for creating worker processes to distribute the workload across all available CPU cores, offering a simple and efficient way to optimize performance.
Implementing clustering in Node.js with the cluster module in under 20 lines of code can detect CPU cores, spawn worker processes, and automatically restart dead workers, enhancing performance and resource utilization.

Deploying and Exposing Go Apps with Kubernetes Ingress, Part 1

Kubernetes Ingress is crucial for managing external access to services, offering advanced traffic control features like path-based routing, SSL, and load balancing.
Ingress vs. Services: Ingress improves routing capabilities over Services by enabling path-based and host-based routing for more sophisticated traffic management.
Introduced in Kubernetes v1.1, Ingress became stable in v1.19, providing a crucial tool for modern web apps needing smarter routing and security.
The tutorial demonstrates building Go services (API and Web) deployed with Kubernetes Ingress for routing external HTTP traffic based on URL paths.
API and Web services are containerized, Kubernetes cluster is set up using Kind, NGINX Ingress controller is deployed, and Ingress rules are defined for routing.
NGINX Ingress controller is implemented for managing routing and load balancing in the Kubernetes cluster.
Deployment configurations for API and Web services are created along with respective Service definitions for internal access.
Ingress resources are set up using defined routing rules based on URL paths to direct traffic to the appropriate services.
Verification steps ensure all components are running, and testing with cURL confirms the expected service responses through Ingress routing.
The project showcases the power of Ingress in managing complex traffic patterns in microservices architectures, enhancing external access and routing capabilities.
