Building storage-first serverless applications with HTTP APIs service integrations

Over the last year, I have been talking about “storage first” serverless patterns. With these patterns, data is stored persistently before any business logic is applied. The advantage of this pattern is increased application resiliency.

Scaling services with Shard Manager

We look at how Shard Manager is fully integrated in Facebook’s infrastructure ecosystem and provides a holistic, end-to-end solution supporting basic shard failover as well as sophisticated load balancing, shard scaling, and operational safety. Over the years, as we’ve expanded in scale and functionalities, Facebook has evolved from a basic web server architecture into a complex one with thousands of services working behind the scenes. It’s no trivial task to scale the wide range of back-end services needed for Facebook’s products.

3 Years of Kubernetes in Production–Here’s What We Learned

We started out building our first Kubernetes cluster in 2017, version 1.9.4. We had two clusters, one that ran on bare-metal RHEL VMs, and another that ran on AWS EC2. Today, our Kubernetes infrastructure fleet consists of over 400 virtual machines spread across multiple data-centres.

What happened to our infrastructure when a customer got over 10 million page views in a few hours?

Designing Edge Gateway, Uber’s API Lifecycle Management Platform

How we upgraded PostgreSQL at GitLab.com

We explain the precise maintenance process to execute a major version upgrade of PostgreSQL. The biggest challenge was to do a complete fleet major upgrade through an orchestrated pg_upgrade. We needed to have a rollback plan to optimize our capacity right after Recovery Time Objective (RTO) while maintaining a 12-node clusterâs 6TB-data consistent serving 300.000 aggregated transactions per second from around six million users.
