Netflix is known for its loosely coupled and highly scalable microservice architecture. Independent services allow for evolving at different paces and scaling independently. Yet they add complexity for use cases that span multiple services. Rather than exposing 100s of microservices to UI developers, Netflix offers a unified API aggregation layer at the edge.

A couple of years ago, my first few days on a new web performance project were always slow going. So many false starts, tedious workflows, and a complete lack of efficiency really made it difficult for me to find momentum. All through no fault of the client or the project, but through huge flaws in my own approach. In a bid to address this, I introduced a new tool into my arsenal so that I could hit the ground running much faster, and get answers to my clients much sooner.

Growing up in the Netherlands, American football was largely a foreign concept to me. My version of football was The Beautiful Game , or as most Americans know it, soccer. Football, futbol, soccer, or whatever else you call it, will always be something I’m deeply passionate about, especially my hometown team, Ajax. When I joined Amazon and Seattle became my new home, I began to see how my colleagues shared this same level of passion for American football – and particularly the fervent fans known

When I first stumbled on the idea of skeleton screens, thanks to Luke Wroblewski talking about them back in 2013 , I latched onto them pretty quickly. I have never been a fan of progress bars and spinners, and skeleton screens seemed like a smart step in the right direction. For those unfamiliar, a skeleton screen is a method of displaying the outline (skeleton) of the content to come, typically using gray boxes and lines instead of a progress bar while content is loading.

Two new technologies, BTF and CO-RE, are paving the way for BPF to become a billion dollar industry. Right now there are many BPF (eBPF) startups building networking, security, and performance products (and more in stealth), yet requiring customers to install LLVM, Clang, and kernel headers – which can consume over 100 Mbytes of storage – to use BPF is an adoption drag.
