"Migrating 500 Nodes from Rackspace to Google Cloud with Zero Downtime"
The story of how we migrated around 90 clusters with over 500 nodes from Rackspace in the UK to Google Cloud in Belgium — saving money and surviving Brexit. How we managed this with zero production downtime, the problems and solutions we encountered along the way, and an example of using Cassandra DCs to migrate data across geographical boundaries.
