Features Of Microservices

Microservices allow for multiple scaling strategies, which can even be combined:

• vertical scaling: memory and CPUs are added to make things go faster
• horizontal scaling: the load is shared between multiple identical instances behind a load balancer
• sharding: the load is routed to a different instance depending on the data it needs to access
• functional decomposition: the service is split into smaller services with technologies and scaling strategies specific for each kind of load
