I’m speaking at DataStax Accelerate:
“Migrating 500 Nodes from Rackspace to Google Cloud with Zero Downtime”
This is the story of how we migrated round 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 on the way. An example of using Cassandra DCs to migrate data across geographical boundaries.
I have written a series of blog posts to go with the presentation:
Moving Cassandra Clusters without Downtime – Part 1
Moving Cassandra Clusters without Downtime – Part 2
Moving Cassandra Clusters without Downtime – Part 3
