How to Choose Your First Microservices


Are you early in your microservices journey? Maybe you’ve decided you need to start deploying applications outside your monolith but you haven’t cut any code yet. Or maybe you’ve put your first few services into production and addressed some of the first pains that happen when you start on that path.

A common question that comes up for teams at around this time is:

It’s even more important than with a monolith, because in a service-oriented architecture you’re making a lot more of your system’s functionality directly exposed to the network, and that puts it in closer reach of would-be attackers, or “increases the attack surface” as a security pro would say.

So last week I presented another talk entitled “Microservices Security: All the Questions You Should Be Asking”.

Microservices Security: Let’s Share What We Know!

I want to tell people all about what we’ve been doing about security at Tyro lately. Security is incredibly important to the IT community and I think it’s imperative that we help each other improve. I want to share with the world some of the problems we’ve dealt with and some of the great solutions our team has built. Continue reading
