Docker Swarm: A simpler alternative to Kubernetes, Docker Swarm manages?

Short answer: clusters of Docker engines and provides features for scaling, load balancing, and service discovery. In microservices, orchestration is crucial to managing complex systems and scaling individual services as needed. Example: Kubernetes can automatically scale the Inventory Service when traffic increases and roll out updates to the Payment Service without downtime.

Real-world example (ShopNest)

ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments.
