The snitches are donated to the Apache Cassandra project from the respective cloud providers. For example, GoogleCloudSnitch was contributed by Brian Lynch (CASSANDRA-7132) who at the time was a Google Cloud Architect and CloudstackSnitch was contributed by Pierre-Yves Ritschard (CASSANDRA-7147) who is CTO at Exoscale, a Cloudstack provider.
Yoshua Wakeham submitted AzureSnitch (CASSANDRA-9387) but it stalled pending the release of C* 4.0 so it's not available yet.
I understand the convenience that a cloud provider snitch affords users but one can argue that even when your organisation exclusively uses a specific provider, GossipingPropertyFileSnitch should still be the default choice. GPFS is more flexible and works with hybrid clouds -- you can have a mix of nodes in AWS, Azure, GCP and even on-premise.
Let's say your company exclusively uses GCP at the moment. When you decide to expand your cluster to another cloud provider, you'll need to change to a provider-agnostic snitch like GPFS. Snitches determine how replicas are distributed in a cluster and so switching snitches requires a lot of planning and it can be a costly exercise. For this reason, we recommend using GossipingPropertyFileSnitch right from the start in all cases.
For more info, see the doc pages on Snitches and Switching snitches. Cheers!
@satvantsingh_190085, GossipingPropertyFileSnitch works optimal and best across any type of environment (on-prem or in cloud). This should be your go-to snitch for production use. At the time of writing, there is no snitch available in particular for Azure.
