I like to watch a IT related presentations. Those give you a lazy way of grasping the idea of “what’s up” in particular subject. It’s grasping because by watching you won’t learn actual skills, but you will know what exists, where are the dragons hidden and where to look deeper. What’s more, if you are bored, you can always skip some parts or go to next presentation - which is extremely important in our fast-paced business. And most importantly - always learn from the best.

Today I recommend you following presentation: LinkedIn’s Active/Active Evolution - Erran Berger
Why? Active/active architecture is probably one of the most popular solutions for scaling existing monolith. Check out where you can expect problems and how LinkedIn team solved them.
