When we break down a monolith into microservices, we trade one large, complex application for dozens or even hundreds of small, fast-moving services.
This brings incredible benefits like agility and independent scaling. But it also creates a new, hidden complexity: the network. Suddenly, simple function calls become unreliable network requests.
How do you manage security, reliability, and observability for this chaotic web of communication?
This is where a Service Mesh comes in. It’s an infrastructure layer that acts like air traffic control for your microservices, managing the complex interactions between them, and providing powerful capabilities without requiring any changes to your application code.
