2021-06-04 11:02:58 ​​A short article by Julia Evans about why OSI model doesn't map to TCP/IP really well. And why sometimes it's just easier to say things like "TCP load balancer" or "Ethernet switch" rather than "later 4", "layer 2", etc.

tl;dr: primarily, because OSI is old.

Also, there is a diagram of your usual network packet as a bonus. Открыть/Комментировать

2021-06-02 12:05:06 Consul Service Mesh for Amazon ECS is now in the Tech Preview.

This means that you can deploy Consul Service Mesh on Fargate type ECS using official Terraform modules. However, only setups for Dev are supported right now, i.e. the official module deploys only a single dev/testing Consul task for now. This will be changed before Consul Service Mesh for AWS ECS hits GA.

2021-05-31 11:29:14 Introducing Argo Rollouts v1.0

Now, for those, who's not familiar with Argo universe, there are Argo, ArgoCD, and Argo Rollouts. All these tools are developed under the same umbrella and are complimentary to each other, but they are not the same thing.

Argo Rollouts manages iterative deployments aka progressive delivery aka canary releases. However, progressive delivery is a broader term. Basically, you roll out your application gradually in an automated way based on the health metrics.

Currently, Argo Rollouts supports such metrics providers as: Prometheus, Wavefront, DataDog, NewRelic, Kayenta, custom Kubernetes Job, and custom Web check. And it supports various traffic controllers like: Linkerd, Istio, AWS LoadBalancer, Ambassador, and Nginx.

So, what's new in version 1.0?
- New Argo Rollouts UI
- Ability to reference existing Deployment workloads instead of inlining a PodTemplate at spec.template
- Richer Prometheus stats and Kubernetes events
- Support for Ambassador as a canary traffic router
- Support canarying using Istio DestinationRule subsets

You can read the full changelog in the GitHub release description.

Also, they have a roadmap, so you can check, what's coming next

2021-05-30 12:25:41 Gatus is a health dashboard written in Go.

It has minimalistic configuration and allows you to set multiple conditions to label an endpoint as "healthy".

Also, you can host it on your own inside your private network. So, if you have security requirements of not to allow external health checkers into the perimeter, this could be a good way to go.

2021-05-28 11:47:46 QUIC - a planned successor of TCP - is now formalized as RFC 9000.

QUIC was initially developed at Google, but later adopted by IETF. It provides some TCP-like features on top of UDP in order to overcome latency and packet loss, especially in the last mile.

HTTP/3, which is built on top of QUIC is not formalized yet, but it's following closely behind. So, it will be likely released soon as well.

So, with HTTP/3 around the corner, have you already switched to HTTP/2?

2021-05-27 18:18:02 Job offer negotiations as well as compensation ranges themselves are always hot topics for discussions not only in software development.

Needless to say that the skills to negotiate are important and help you to get a better deal (sometimes even without changing a company).

Today in the CatOps Chat we are going to talk about compensation and salary negotiations in general. Voice chat starts today at 17:00 UTC in the group chat. Important thing to mention: the conversation is usually in Russian or Ukrainian, or (more frequently) both.

And it's not all yet. Here is an article to prepare yourself for such a discussion. It was sitting in my reading list for a few months now, but it looks like today the time to read it has come eventually. I'm happy to share these articles with you as well!

- Ten Rules for Negotiating a Job Offer. (Part I)
- How Not to Bomb Your Offer Negotiation. (Part II)

Enjoy and auf wiederhören!

2021-05-25 12:59:42 Why sharing a single article if you can share the whole magazine?

Increment is an online and printed magazine about software and technologies, which is published in a good-old format of monthly issues.

Each issue has its own topic and the 16th dated February 2021 is dedicated to the topic of Reliability!

Enjoy more than 10 articles on reliability, chaos engineering, etc. as well as case studies from various companies. Also, you can buy a printed magazine version if you want.

Increment has already covered topics like On-call, Remote work, Cloud, etc. Honestly, this is the best publishing finding for me this year. I'll definitely dig into it and probably even order a printed version as well!
