Replication
Explore the concept of replication in distributed systems to improve availability. Understand how storing multiple copies of data across nodes helps the system stay functional during failures. Learn the differences between pessimistic and optimistic replication and their impact on consistency and performance.

Partitioning can improve the scalability and performance of a system by distributing data and request load to multiple nodes.
Another dimension that benefits from using a distributed system is known as availability.
Availability
Availability refers to the ability of the system to remain functional despite failures in parts of it.
Mechanism to achieve availability
The technique we use to achieve availability is replication. ...
