Istio 1.5 introduces simpler architecture, improving operational experience

Istio 1.5 introduces the Istiod binary, which significantly simplifies Istio’s architecture, improving operational experience. One thing we’ve heard from the mesh administrators and operators who use Istio is that its complexity makes it hard to adopt and integrate with their current stack. I’ve been involved with the development of Istio since Istio 0.6, and I’ve seen it become increasingly complex over time.

Why We Leverage Multi-tenancy in Uber’s Microservice Architecture

Multi-tenancy lets Uber tag requests coming into our microservice architecture, giving us the flexibility to route requests to specific components, such as during testing scenarios. The performance of Uber’s services relies on our ability to quickly and stably launch new features on our platform, regardless of where the corresponding service lives in our tech stack. Foundational to our platform’s power is its microservice-based architecture, a commonly used structural style where applications consist of interoperating services.

An AWS Bill Analysis: Changelogs.md

He’s been remarkably transparent with changes he’s made to make running it more cost-efficient—and since he’s running this in a personal account, this is real money rather than AWS Credits (motto: “Like Bitcoin but less obnoxious”). The entire system is open-sourced and, after a bit of bargaining, he let me into his account to take a look at the bill. In this post, we tear down what he’s running, how it could be optimized, and what it takes to get there.

Building a Design Systems Library with Figma & Scripter

Over the past few months, I’ve been helping Lyft build the initial version of our Figma design systems library, which contains all of the colors, text styles, and components used by designers across the company. As we worked on the project, we began to notice patterns of time-consuming tasks, some examples being: Generating helpful descriptions for our 500+ color styles. Optimizing each of the 900+ icons in our icon library.

Kubernetes 1.19 Will Embrace Sidecars

Kubernetes 1.17 became generally available on Dec. 9 bringing with it a host of new stable enhancements, but what’s perhaps more interesting is not what’s in that release, but what’s missing. The release notes identify 22 enhancements in total, which is half what was originally expected to debut in the release. Among the enhancements that were originally planned for the release but didn’t end up making it into Kubernetes 1.17 is full support for sidecar containers, but don’t worry, it’ll likely come together in time for Kubernetes 1.19.

SmartShop, Growing from 2 stores to the whole estate

When developers write blog posts to do with scaling, they more often than not talk about a particular part of their tech stack which was limiting their ability to scale, or even their architecture as a whole. I’ve found that people seldom talk about tackling the problem of scale of a whole product on a macro-level — how do you grow a digital product from a small trial to a business-as-usual service used by millions of customers? Self-scanning shopping wasn’t revolutionary when I joined Sainsbury’s 4 years ago.

Istio in 2020

A vision statement and roadmap for Istio in 2020. Istio solves real problems that people encounter running microservices. Even very early pre-release versions helped users debug the latency in their architecture, increase the reliability of services, and transparently secure traffic behind the firewall.
