• CAP theorem states that it is impossible for a distributed software system to simultaneously provide more than two out of three of the following guarantees (CAP): Consistency, Availability, and Partition tolerance. When we design a distributed system, trading off among CAP is almost the first thing we want to consider. CAP theorem says while designing a distributed system we can pick only two of the following three options:

• Consistency: All nodes see the same data at the same time. Consistency is achieved by updating several nodes before allowing further reads.
• Availability: Every request gets a response on success/failure. Availability is achieved by replicating the data across different servers.
• Partition tolerance: The system continues to work despite message loss or partial failure. A system that is partition-tolerant can sustain any amount of network failure that doesn’t result in a failure of the entire network. Data is sufficiently replicated across combinations of nodes and networks to keep
