Let me add some more information to what Jacky wrote above. That path is via our docs.memsql.com site.
We also have MemSQL listed as a product in AWS Marketplace. Link here https://aws.amazon.com/marketplace/search/results?x=24&y=14&searchTerms=MemSQL
We have a BYOL and a PAID version. For the PAID version you can pay by the hour for MemSQL usage.
The BYOL option allows you to create very large clusters up to 100 nodes.
The PAID listing allows you to create clusters up to 10 nodes.
The CloudFormation Template (CFT) used in both the AWS as well as our docs link is the same.
The AMI in all the above CFTs are optimized to use OS configuration parameters appropriate for MemSQL and it also uses the faster ‘gp2’ Volume type for the EBS.
Currently we do not support cluster expansion or shrinking with the CFTs mentioned above.
Very soon, we are planning to release an offering which will allow true elasticity in terms of on-demand cluster expansion. Stay tuned!
Thanks for your interest,
