Now that the technology world is increasingly maturing around the notion of cloud adoption in general, the benefits of multi-cloud deployments compared to single-cloud ones are also becoming more widely recognized:

  • increased resilience against failures that can take out an entire cloud region or cloud provider (along with your backups!),
