We will explore the workings of the Team Topologies model and how Site Reliability Engineering (SRE) teams can fit into it. In more detail, I will share with you the following: an overview of the team topologies model the 4 team modalities it proposes, and finally… where SRE teams fit in team topologies Let’s get … Read More
Introduction Every time you push a button like the one below to request an Uber ride, you activate a sequence of (micro)service requests. You’d never know unless you look under the hood because most of these services run solely in the background. Yet every service contributes to the start and completion of the Uber ride … Read More
In this article, I will share how tracing and more specifically Jaeger tracing can fit into your wider software observability strategy. Before we get into tracing, let’s define observability. What is observability? Observability is a comprehensive means of gaining data on how software services perform in production. This data gives you a picture of the … Read More
This article explores 2 simple ways for SREs to drive better practices and code hygiene within infrastructure-as-code (IAC) tooling like Terraform. Why bother? Because of its centrality to cloud infrastructure efficiency, it’s highly likely that you will get involved with an IAC problem at some point in your SRE career. I will mention Terraform from … Read More
This article aims to help engineering leaders consider issues before starting a software reliability team. Since I am an advocate for Site Reliability Engineering (SRE), we will now refer to such a team as the “SRE team”. Besides creating a new team, leaders face many responsibilities that are often invisible to individual contributors and their … Read More
As a generative leader and mental health advocate, I am wary of seeing such a morbid term being thrown around for what should be a learning experience that advances culture. This post will differ from my usual positive posts about Site Reliability Engineering (SRE). Please bear with this because I’m an otherwise forward thinker. Two … Read More
Agile software delivery is de rigeur of modern software. However, as complexity increases, there’s a high risk of frequent, high-velocity breaking software-in-production. Software-in-production is when the software is accessible by users. That’s where Site Reliability Engineers (SRE) can come to support the Agile software team’s efforts. Who are Site Reliability Engineers? Site Reliability Engineers (SREs) … Read More
Google’s book on SRE, Site Reliability Engineering (2016), has captured wide acclaim in the software operations world. One of the most discussed aspects in SRE circles about the book is its SRE hierarchy. The hierarchy has merit, but it’s also flawed in a way that would prevent you from educating people about SRE. I’ll get … Read More
4 “Golden Signals” in Site Reliability Engineering Latency is the delay before data is completely transferred from one end to another. It is typically measured in milliseconds (ms) Throughput is the amount of data that can transfer across within a given period. It can be measured in bits/second. Error rate measures errors occurring in the system, such as … Read More
I recently read a post by Will Lason, who started SRE at Uber. The post is called the Trunks and branches model for scaling infrastructure organizations. Several passages in the post covered how infrastructure teams can evolve from the startup phase. I felt it would be easier to comprehend the dense-and-rich advice with a visual … Read More
