AKS Cluster Performance: How to Better Operate Kubernetes in Azure

AKS is the managed service from Azure for Kubernetes. When you create an AKS cluster, Azure creates and operates the Kubernetes control plane for you at no cost. The only thing you do as a user is to say how many worker nodes you’d like, plus other configurations we’ll see in this post. So, with that in mind, how can you improve the AKS cluster performance of a service in which Azure pretty much manages almost everything?

Rails Migration A Complete Guide

A Rails migration is a tool for changing an application’s database schema. Instead of managing SQL scripts, you define database changes in a domain-specific language (DSL). The code is database-independent, so you can easily move your app to a new platform. You can roll migrations back, and manage them alongside your application source code.

Kubernetes vs Docker: How to Choose

If you’re thinking about using containers to manage an application, there are a lot of options for technologies to use. It can be difficult to even know where to begin to make a decision. One common question is whether someone should use Docker vs Kubernetes for managing their application containers. This is a misleading question. In truth, Docker and Kubernetes aren’t competing technologies. There’s no need for them to face off.

DevOps Engineer Starter Guide

Everybody climb aboard the hype train with me. Today, we’re going to study a new job title: the DevOps engineer. This role is getting popular in the same way that the full-stack developer role became popular before it. In fact, one could argue that the DevOps engineer is an extension of the full-stack developer in that both seek to extend our ownership of our software.

Docker Image vs Container: Everything You Need to Know

Docker is a powerful tool for creating and deploying applications. It simplifies rolling out applications across multiple systems and is a useful tool for integrating new technologies. An application that runs using Docker will start up the same every time on every system. This means that if the application works on your local computer, it’ll work anywhere that supports Docker. That’s great news! It simplifies your development process and can be a powerful tool for continuous delivery.

Ruby Debugger Using Visual Studio Code

No matter how carefully coded, reviewed, and tested your Ruby code is, odds are good that at some point you’ll cause a catastrophic failure to at least one system you’re responsible for. How do you prepare yourself? You need a Ruby debugger. In this post, I’ll cover the whole Ruby debugger process—from finding the issue to determining the root cause. Use these instructions for debugging a single Ruby file, a Rails app, or a gem.

What Is CICD? What's Important and How to Get It Right

We’re on the verge of something here, people. A growing number of companies are shipping software in minutes. Yeah, you read that right. Minutes. Not hours, not weeks, months, or longer. Minutes. Often, teams struggle to ship software into the customer’s hands due to lack of consistency and excessive manual labor. Continuous integration (CI) and continuous delivery (CD) deliver software to a production environment with speed, safety, and reliability.

Restify vs. Sails vs. Hapi: Node.js Framework Comparison

In the last decade, Node.js has rapidly risen in popularity as a server-side programming language. With that popularity, we’ve seen no shortage of frameworks aiming to make developers’ lives easier. Although they are lesser-known than other Node.js frameworks, Hapi, Sails, and Restify are a few options that have a lot to offer.
