As everything good in life, serverless also comes with its downsides. One of them is the infamous “cold start”. In this article, we’ll cover what they are, what influences serverless startup latency, and how to mitigate its impacts in our applications. What is a cold start? Cold start refers to the state our function when…
Serverless lets you deploy applications far away in a data center of a cloud provider. This relieves you of the lion’s share of operational burdens. The more you buy into your cloud provider’s ecosystem, the less you have to do yourself: no more OS updates or database bugfix installations. But you still need to do some operation-related work on…

They might provide just a few lines of code, but these lines are usually what hold the whole architecture composed of many managed services together. Event-driven architecture is what this style is called, and it’s most prevalent in serverless applications. API gateways collect requests…
