1. State of Service Mesh in 2021
   Jimmy Song went through an emerging ecosystem of service meshes and their adaptation. The article explores the gap in service mesh technology and evolving projects which will fill the gap. I am particularly excited about the sidecar-less model of the service mesh, introduced by Cilium.

2. How Paypal Scaled Kubernetes to 4000 Nodes and 200,000 Pods
   A lot of things can go wrong and it is particularly challenging to run Kubernetes at such a scale. Learn how they used k-bench for load testing and how they optimized the Kubernetes core components such as API server, scheduler, and controller.

3. Alex recently shared how he has solved the serverless cold start problem with OpenFaaS. Almost all serverless offerings have this problem by design, many have been using a warm pool of containers, and some folks at Cloudflare did it very differently for their edge serverless compute - read their implementation here.

4. How to start with eBPF

   The current trend set by industry experts and thought leaders around eBPF is attracting all the eyes and it is revolutionary. The possibility of extending Linux kernels safely has never been done in the history of Linux in the last 30 years. That is the reason, all big corps are now focussing on how they can use this technology to create awesome products.

5. Roblox shared their postmortem of the October outage that affected nearly 50M gamers for 73 hours. It is a very well-written and detailed postmortem that I enjoyed reading and learned a few new things about their infrastructure.

Opportunities

1. Last9inc is looking for a technical writer. It is a great team to work with.

Piyush Verma @realmeson10

Who is the best Technical writer that you know of? @last9inc is about to launch some "bad a$$' tooling around for the world of Openmetrics. But, the story can only be as good as it's text. If your referral works, I will be your SRE for a day 🙂

Books or YouTube channels that I follow.

• System Design Interview - Alex Xu - Not only for interview prep but you can learn a lot about how to evolve your system design and architecture.

• Vivek’s Youtube Channel teaches you how to write Kubernetes Controllers and Operators. Also, he has deep dives in understanding various components of Kubernetes.

Follow me on LinkedIn and Twitter for more real-time updates and happy to hear your feedback about this newsletter. Please share with colleagues and friends.
