ThoughtSpot can be deployed in your AWS environment by deploying compute (VM) instances in your Amazon VPC as well as an underlying persistent storage infrastructure. Currently two configuration modes are supported by ThoughtSpot:
- Mode 1: Compute VMs + EBS-only persistent storage
- Mode 2: Compute VMs + EBS and S3 persistent storage
The cost of infrastructure for deploying ThoughtSpot is cheaper when using S3. However, there are differences in where data is loaded, as well as in the backup and restore procedure. For assistance in choosing the best mode for your organization, contact your ThoughtSpot representative. For more information on purchasing ThoughtSpot on AWS, see: ThoughtSpot Pricing.
All AWS VMs in a ThoughtSpot cluster must be in the same availability zone (and therefore, also in the same region). ThoughtSpot does not support deploying VMs in the same cluster across availability zones. For more information, see Regions and Availability Zones in Amazon’s AWS documentation.
ThoughtSpot AWS instance types
The following sections contain the supported and recommended instance types for a ThoughtSpot AWS deployment. When setting up your cluster in AWS, use the information here to select an instance type, configure the number of instances required for the storage you need, and add data volumes to your cluster.
For example: If you were deploying a total cluster data size of 1 TB using the standard r5.16xlarge instance type, you would need 4 instances (VMs), because the per-VM user data capacity of that instance type is 250 GB. If you were deploying EBS-only data volumes, you would need 2x1 TB data volumes per VM.
VMs with EBS-only persistent storage
| Per VM user data capacity | Instance type | CPU/RAM | Recommended per-VM EBS volume | Required root volume capacity |
|---|---|---|---|---|
| 20 GB | r4.4xlarge, r5.4xlarge | 16/122, 16/128 | 2X 400 GB | 200 GB for each node |
| 100 GB | r4.8xlarge, r5.8xlarge | 32/244, 32/256 | 2X 400 GB | 200 GB for each node |
| 192 GB | m5.24xlarge | 96/384 | 2X 1 TB | 200 GB for each node |
| 250 GB | r4.16xlarge, r5.16xlarge | 64/488, 64/512 | 2x 1 TB | 200 GB for each node |
| 384 GB | r5.24xlarge | 96/768 | 2X 1.5 TB | 200 GB for each node |
VMs with EBS and S3 persistent storage
| Per VM user data capacity | Instance type | CPU/RAM | Recommended per-VM EBS volume | Required root volume capacity |
|---|---|---|---|---|
| 20 GB | r4.4xlarge, r5.4xlarge | 16/122, 16/128 | 1x 500 GB | 200 GB for each node |
| 100 GB | r4.8xlarge, r5.8xlarge | 32/244, 32/256 | 1x 500 GB | 200 GB for each node |
| 192 GB | m5.24xlarge | 96/384 | 1x 500 GB | 200 GB for each node |
| 250 GB | r4.16xlarge, r5.16xlarge | 64/488, 64/512 | 1x 500 GB | 200 GB for each node |
| 384 GB | r5.24xlarge | 96/768 | 1x 500 GB | 200 GB for each node |
For most instances, the per VM recommended user data capacity is set at 50% of the available RAM on the instance. However, in the case of our 16CPU/128GB RAM and 32CPU/256GB RAM instances, we support user data sizes below those numbers to budget for application overhead.
