Why we need a multi-cloud database, and how to build one

The text discusses the benefits and challenges of building multi-cloud companies and applications. It explains that using multiple cloud providers can help mitigate risks associated with relying on a single provider, such as outages or vendor lock-in. Multi-cloud deployment also allows organizations to take advantage of best-in-class services provided by each cloud provider. The text provides an example of deploying CockroachDB across three different cloud providers using Kubernetes and network VPNs. It highlights the importance of IP addressing, name resolution, and cost management in multi-cloud setups.
