Microservices architecture consists of small, independent services communicating via APIs, each responsible for specific functionality, promoting scalability and maintenance.

A load balancer distributes incoming traffic across servers, ensuring resource efficiency, fault tolerance, and high availability.

Caching stores frequently accessed data for faster retrieval, reducing backend load, improving performance, and enhancing user experience.

A CDN is a network of servers for delivering content efficiently to users based on geographic proximity, reducing latency and load times.

Monolithic is simple but less scalable; microservices offer scalability and flexibility but are complex to manage.

Stateless services don't retain client data between requests; stateful services maintain client state, useful for sessions and transactions.

The CAP theorem states that in a distributed system, you cannot simultaneously guarantee Consistency, Availability, and Partition Tolerance at all times.

Ensure consistency using strong consistency models, two-phase commits, optimistic concurrency control, and conflict resolution strategies.

A reverse proxy routes client requests to appropriate servers, providing load balancing, SSL termination, caching, and security.

A message broker facilitates communication in distributed systems through asynchronous messaging, used in event-driven architectures and high-volume scenarios.
