Vertical Scaling:?

• Scaling Up: This involves increasing the resources (CPU, memory) for a

specific microservice instance. Vertical scaling is more common for monolithic

applications or services that require more powerful hardware but is less

optimal for microservices due to their distributed nature.

• Example: Increasing the memory or CPU for a service like the Payment

Service that requires more processing power.

Best practice: For microservices, horizontal scaling is preferred because it increases

resilience and fault tolerance by distributing traffic and workloads across multiple instances.
