Summary
This offering uses open-source Terraform-based automation to set up a stateless 3-tier for either stateless or stateful web application in a single availability zone. This offering implements best practices to avoid a single point of failure, such as placement groups for multiple VSIs and application load balancers to spread client requests. For more details, refer to the following link.
NOTE: File share storage is limited availability. For more information refer to the following link.
Day 2/Post Provisioning
This offering does not install any software packages. You will need to install the software packages and system configurations. In addition, you may need to update some of the default IBM Cloud policies (i.e., security groups, front-end listeners, LB health check, etc.) through the IBM Cloud console per applications requirements.
Cost Estimation
This is just an estimated cost for guidance purposes. The total cost will vary depending on region, number of VSIs, VSIs profiles, egress internet traffic, etc. The below was done with the default values and deployed in the us-east region.
