Meta社が開発して自社で使っているサービスメッシュであるServiceRouterについての紹介。 ライブラリとしてアプリコード内での稼働をサポートしており、同社のトラフィックの内99%はこの形態で稼働しているらしい。これによりサイドカーコンテナ稼働分のコンピューティングコストを削減している。仮にサイドカーで稼働させた場合、Metaのスケールだとt4g.smallのAWS EC2が175万台必要になるらしい！ ServiceRouter を使わなくてもCiliumやIstioのAmbient モードにする事でサイドカーコンテナ分のコスト削減効果は狙えそう。 micahlerner.com/2024/03/28/s…

This case study explains how Meta doesn't use regular Service Meshes and instead opted for ServiceRouter: a service mesh-like tool that lives inside the application ➤ micahlerner.com/2024/03/28/s…

This has a few different names, like "Scientist Pattern" or "Shadow Deployment" cloud.google.com/architectur… It's a really good idea. Especially if you have done something like a big refactor. At meta it was built into ServiceRouter but I don't recall seeing anyone use it much.

I just published my review of ServiceRouter, Meta's system for microservice discovery, request routing, and global load balancing: newsletter.micahlerner.com/p… While there are well known open source systems for routing traffic (e.g. Linkerd, Envoy, and Istio), there are a few interesting components of ServiceRouter: - ServiceRouter supports embedding inside Meta application code, significantly reducing cost from the common pattern of running separate “service mesh” infrastructure - the paper estimates that a separately deployed service mesh at Meta scale would need the equivalent of 1,750,000 AWS t4g.small VMs. - ServiceRouter is one of the first pieces of routing infrastructure deployed at hyperscale discussed in research. - ServiceRouter is able to handle sharded stateful services (related to my previous paper review on ShardManager!) - The system handles load balancing across regions using the novel idea of “Latency Rings”

The next paper I’m going to read/write about is “ServiceRouter: Hyperscale and Minimal Cost Service Mesh at Meta”: usenix.org/conference/osdi23… The paper is unique in that it describes a system that supports several different ways of routing RPCs. Alongside the “standard” proxy/sidecar-based implementations for routing RPCs, ServiceRouter also allows directly embedding routing functionality inside of an application binary, an approach that dramatically reduces cost! The paper also talks about challenges of running an RPC routing system at hyper scale, and addresses how the system supports sharded services (discussed in my previous paper review on ShardManager, micahlerner.com/2022/01/08/s…)

The next one is about ServiceRouter, Meta’s service mesh (RPC system): linkedin.com/pulse/service-m…

Paper on Meta’s Service Mesh ServiceRouter is out! Most interesting findings: 1. Using libraries instead of sidecar container for routing vast majority of traffic! 2. No Ebpf. Sticking to L7 for sidecars. usenix.org/system/files/osdi…
