Load Balancing Fundamentals

Image
Before we dive into the specifics of tools like HAProxy, Nginx, or cloud-native solutions, we need to build a general overview of what load balancing actually is. At its simplest, load balancing answers a single question: When a client wants to talk to "the service," which specific server should actually handle that request? Why Do We Need It? You need load balancing the moment a single server can no longer (or should no longer) handle your traffic alone. It provides three core pillars for your infrastructure: Scalability: The ability to spread traffic across many servers instead of one. Availability: If one server fails, the load balancer shifts traffic to the healthy servers. Flexibility: You can add, remove, or replace backend servers without the client ever noticing. Everything else - algorithms, health checks, SSL termination, routing rules - exists in service of that one core job. The Four Layers of Traffic Management It helps to think of traffic control as happening ac...

Setting Up OpenFaaS in Kubernetes

Image
Serverless computing has revolutionized how we build and deploy applications, allowing developers to focus on code without managing underlying infrastructure. OpenFaaS brings this power to your Kubernetes cluster, providing a flexible and powerful platform for deploying functions. In this guide, we'll walk you through the process of setting up OpenFaaS locally, and prepare to deploy your first function. Choosing Your Kubernetes Environment Cloud Kubernetes Options For production-ready, scalable environments, cloud providers offer managed Kubernetes services Azure Kubernetes Service (AKS)  Amazon Elastic Kubernetes Service (EKS) DigitalOcean Kubernetes Service (DOKS) Google Kubernetes Engine (GKE) Local Kubernetes Options For development and testing purposes, setting up a local Kubernetes cluster can be incredibly efficient. Minikube: The original "local Kubernetes" solution. Minikube provisions a single-node Kubernetes cluster within a virtual machine (VM), but the...

OpenFaaS Overview

Image
OpenFaaS is a serverless functions framework that lets you deploy functions as Docker containers.With OpenFaaS developers can deploy event-driven functions and microservices to Kubernetes. OpenFaaS brings the following benefits: Portable function platform - cloud or on-premise Use any language to write functions Easy to use - built-in UI, CLI and one-click installation Scalable - can scale up during traffic spikes and scale down when idle For more information, you can check out the OpenFaaS community resources and a list of adopters: OpenFaaS adopters. What Is PLONK? PLONK is an acronym that refers to a stack of cloud native projects, commonly used with OpenFaaS: P rometheus: Metrics and time-series monitoring L inux/Linkerd: Operating system or service mesh O penFaaS: Management and auto-scaling of compute N ATS: Asynchronous message bus / queue K ubernetes The PLONK stack provides a complete platform for building and deploying cloud-native applications, including serverless functi...
