Load Balancing: Round Robin May Not Be the Right Choice

DevOps.com

Based on our experience, we believe Round Robin may not be an effective load balancing algorithm, because it doesn’t equally distribute traffic among all nodes. The post Load Balancing: Round Robin May Not Be the Right Choice appeared first on DevOps.com.

One Year of Load Balancing

Algolia

From the beginning at Algolia, we decided not to place any load balancing infrastructure between our users and our search API servers. This leads to a server load that matches the round-robin DNS resolution. DNS-based load balancing limitations.

Securing a Web Application with AWS Application Load Balancer

Stackery

If you’re still using an Elastic Compute Cloud (EC2) Virtual Machine, enjoy this very useful tutorial on load balancing. That’s what I’m using AWS Application Load Balancer (“ALB”) for, even though I have only a single instance at the moment so there’s no actual load balancing going on.

How a China-Based Bare Metal Service Provider Tackled Kubernetes Load Balancing

The New Stack

Specific to bare metal, for example, Kubernetes platforms lack viable load balancing capabilities. The main issue, he said, with open source load balancing on bare metal is how backend workloads are typically exposed using the load balancer in a Kubernetes cluster.

Advanced Load Balancing and Sticky Sessions with Ambassador, Envoy and Kubernetes

Daniel Bryant

release notes , we have recently added early access support for advanced ingress load balancing and session affinity in the Ambassador API gateway, which is based on the underlying production-hardened implementations within the Envoy Proxy. It’s been my experience that how load balancing is implemented within Kubernetes Services is not always intuitive. Endpoint Routing and Load Balancing In Ambassador 0.52, we introduced a new set of controls for load balancing.

Simplified NGINX Load Balancing with Loadcat

Toptal

NGINX, a sophisticated web server, offers high performance load balancing features, among many other capabilities. However, there is something interesting about tools that configure other tools, and it may be even easier to configure an NGINX load balancer if there was a tool for it. In this article, Toptal engineer Mahmud Ridwan demonstrates how easy it is to build a simple tool with a web-based GUI capable of configuring NGINX as a load balancer
