How Uber improved load balancing with real-time dynamic subsetting for millions of containers.

Subsetting is a common technique used in load balancing for large-scale distributed systems. In this blog post, we will briefly introduce current Uber’s service mesh architecture that has been powering thousands of critical microservices in Uber since 2016. We will then discuss the challenges we faced when trying to scale the number of tasks in the mesh and issues with our initial subsetting approach. We’ll finish with how we came up with the real-time dynamic subsetting solution and its results in production.

One of the super powers of APIs.json is the ability to evolve the human-readable aspects of API operations into machine-readable ones–as this is how we are going to scale to deliver the API economy all of us API believers envision in our minds eye. I saw what Swagger (now OpenAPI) had done for API documentation back in 2013, and I wanted this for the other essential building blocks of our API operations. A decade later I am still translating our getting started, plans, SDKs, road map, change log, and support into machine-readable artifacts as part of our API Commons work, but I am still working to translate documentation into machine-readable artifacts as well.

I am pretty happy with manually searching Google and Bing for APIs across different spaces. The more APIs I add to my APIs.json index of APIs, the more words that appear as tags. So I regularly scroll through the list clicking on different keywords to see what comes up in the top 10 search results. I will be manually doing this on a regular basis, but I am looking to see what I can automate as well, so I wanted to see what the first couple of steps I could take to automate this recurring activity.
