Multi-Cloud Deployment with CockroachDB

This article discusses multi-cloud deployment with CockroachDB, a distributed SQL database designed to survive data center failures and network issues. The author explains the importance of multi-cloud databases in minimizing latency while ensuring availability, using an example scenario where an application receives most of its traffic from the east coast of the United States. The article then provides a step-by-step tutorial on creating a cross-cloud CockroachDB cluster with nodes in three data centers along the eastern seaboard. It covers launching VMs, installing and booting CockroachDB, inserting data into the cluster, simulating data center failure, and concludes by highlighting how multi-cloud support can provide operational flexibility. The author also mentions that most cloud providers charge an egress bandwidth fee for network traffic leaving the data center, which should be considered before launching a multi-cloud cluster.
