Introduction As part of Uber engineering’s wide efforts to reach profitability, recently our team was focused on reducing cost of compute capacity by improving efficiency. Some of the most impactful work was around GOGC optimization. In this blog we want to share our experience with a highly effective, low-risk, large-scale, semi-automated Go GC tuning mechanism. Uber’s tech stack is composed of thousands of microservices, backed by a cloud-native, scheduler-based infrastructure. Most of these services are written in Go. Our team, Maps Production Engineering, has previously played an instrumental role in significantly improving the efficiency of multiple Java services by tuning

I've had a repeated conversation recently about SLO Adoption. The question I get is "Which services should I start with?"And there is a counterintuitive idea I want to share. 🧵— Kit “SLOconf is May 9-12 2022" Merker (@KitMerker) March 17, 2022

The company's SRE journey started three years ago, and it now has reliability teams focused on infrastructure, products and developer productivity. #SRE #reliability

I’ve been thinking about WebAssembly a lot lately.

TSTP (get ready to be shutdown). TERM (heroku default is 25 seconds, elsewhere defined by config / timeout switch).

We are building a distributed file system for your SQLite databases. Kinda weird, huh?

🎉 Announcing fgtrace, a new profiler/tracer for #golang.It captures wallclock timeline views for each goroutine and it's really simple to use:defer fgtrace.Config{}.Start().Stop()Check it out & let me know what you think https://t.co/Ttdm5hl0Vi pic.twitter.com/4iP9SNVypD— Felix Geisendörfer (@felixge) September 19, 2022

Profiler's output file formats.

Addr：https://ebpf.xyz/post/an_introduction_and_practical_tips March 23, 2022 This article introduces developers to eBPF and explains how it can be used to add security, networking, and other capabilities in the Linux kernel space. In Linux architecture, memory is separated into kernel space and user space. The kernel space is used to run the core kernel code and the device drivers. Processes running in kernel space have unrestricted access to all hardware, including CPU, memory, and disks.

We often look at a Service and wonder where to start monitoring the thing let alone what the SLOs should be.  Critical User Journeys help…

Introduction to resilience engineering concepts for software engineers - GitHub - res-eng/resilience-for-software: Introduction to resilience engineering concepts for software engineers

From Erik Hollnagel. ” A system is resilient if it can adjust its functioning prior to, during, or following events (changes, disturbances, and opportunities), and […]

Check out the latest from The Lead Developer at theleaddeveloper.com. On March 28, 1979, at exactly 4 o’clock in the morning, control rods slammed into the reactor core of Three Mile Island Unit #2, halting the nuclear reaction because of a fault in the reactor cooling system. At 4:02, the automated emergency cooling system activated as the reactor core temperature continued to rise. At 4:04, one of the plant operators made the befuddling decision to switch off the emergency cooling system, dooming the reactor to partial meltdown. Why? When something bad happens, it’s easy to just blame someone and move on. Taking the time to find the systemic causes, though, will not only help keep the problem from repeating, it will enable you to build the psychological safety necessary for your team to truly collaborate. Let’s let the story of Three Mile Island teach us how to make our teams stronger through systems thinking and just culture.

Imagine you are in a remote meeting using terms like SLI, SLO, or SLA, and your kid asks you what it means? How would you explain it to them? Or maybe you need to explain it to your boss or a colleague. In this article, I will try to put SLI, SLO, and SLA in a way even your kids would understand… maybe.

Learn about Game Days, a DevOps method for software development and testing teams to build up their readiness to achieve better Incident Management.

Chaos engineering is an implementation of testing the robustness of your application and the readiness of your team in handling application failures.

John Arundel, principal consultant at Bitfield Consulting, shared his thoughts on how to ensure incidents are handled smoothly and quickly. He suggests assigning specific roles to each team member responding to the incident. Red team versus blue team exercises can also be leveraged to ensure the team is prepared to respond accurately and quickly.
