Automatic scaling is one of the biggest advantages of serverless architecture for microservices, ensuring the system can handle sudden surge in traffic without manual intervention.
Serverless architecture is more cost-effective as you are only charged for the actual execution time of functions and don't need to maintain idle servers or pay for unused resources.
Serverless architecture reduces the operational burden on DevOps teams as there's no need to manage server patches, updates, or scaling configurations.
Using serverless platforms for building microservices allows faster development cycles and quicker deployment of new features, as the focus is on writing business logic rather than infrastructure management.
