General Requirements
For general requirements, see Planning, General and Port Requirements.
Specific Requirements
CTERA recommends using the M6 family of EC2 instances for the portal installation: M6i.2xlarge instance type for the primary database and secondary, replication, servers and for application servers that are defined with the CTERA Messaging service. M6i.xlarge instance type for application and preview servers.
Clusters that are memory intensive should use the R6 family.
Note
Amazon often add instance types that are more powerful for the same or even less money. CTERA recommends always checking with CTERA Support for the latest recommendations.
