Question

Is it possible for any service discovery tool to satisfy all the three guarantees (consistency, availability, partition) in a distributed environment?

Answer 1

It is not possible for any service discovery tool to satisfy all the three guarantees, that is, consistency, availability, partition, all together in a distributed environment.

They can appear in a pair, generally keeping the third criteria missing.

According to the CAP theorem, there are three categories of guarantee:

1. CP : This system is tolerant to consistency and partition but is never available

2. CA: This system is tolerant to consistency and availability but never partitioned

3. AP: This system is tolerant to Availability and partition but never consistent
