AWS CloudFormation Increases Stack Instance Limits for StackSets
AWS CloudFormation has increased the number of stack instances you can create per StackSet to manage your AWS resources. Previously, you could create maximum of 50 stack instances per StackSet. Now, you can create a maximum of 500 stack instances per StackSet allowing you to provision more stack instances across accounts and regions from a single template with a single operation.
AWS CloudFormation StackSets is available in the following regions: US East (Ohio), US EAST (N. Virginia), US West (N. California), US West (Oregon), Canada (Central), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), EU (Frankfurt), EU (Ireland), EU (London), and South America (São Paulo).
