Finding the Reasons for your Team's Performance Problems

So, You Want to Move to Microservices?
As I reflected back on my time at LinkedIn, I put together a brief history of its scaling story. We had done the (now) classic migration from monolith to microservices. Just like oh I dunno, Amazon, Google, eBay, Twitter, Netflix, and my current employer Uber (to name a few). And why not? Mic...
