This module was intended to be ran with an Intel Sentinel Policy as Code module that can be found here: https://registry.terraform.io/policies/intel/intel-azure/latest
Azure Managed Instance Apache Cassandra SKU For Azure Managed Instance Data Center Supported Intel SKU are: Standard_D16s_v4, Standard_D32s_v4, Standard_D8s_v4, Standard_DS12_v2, Standard_DS14_v2, Standard_E8s_v4, Standard_E16s_v4, Standard_E20s_V4, Standard_E32s_v4
Dsv4-series sizes run on the 3rd Generation Intel® Xeon® Platinum 8370C (Ice Lake) or the Intel® Xeon® Platinum 8272CL (Cascade Lake). The Dv4-series sizes offer a combination of vCPU, memory and remote storage options for most production workloads. Dsv4-series VMs feature Intel® Hyper-Threading Technology. Remote Data disk storage is billed separately from virtual machines.
DSv2-series sizes run on the 3rd Generation Intel® Xeon® Platinum 8370C (Ice Lake), Intel® Xeon® Platinum 8272CL (Cascade Lake), Intel® Xeon® 8171M 2.1GHz (Skylake) or the the Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors with Intel Turbo Boost Technology 2.0 and use premium storage.
Esv4-series sizes run on the 3rd Generation Intel® Xeon® Platinum 8370C (Ice Lake) or the Intel® Xeon® Platinum 8272CL (Cascade Lake). The Esv4-series instances are ideal for memory-intensive enterprise applications. Evs4-series VMs feature Intel® Hyper-Threading Technology. Remote Data disk storage is billed separately from virtual machines.
NOTE: Please be aware as of May 2023, there is a known discrepency between what is listed as supported SKU's in the Azure Managed Instance Apache Cassandra pricing documenation and what is actually supported in teh portal/cli: Azure Managed Instance Apache Cassandra price documentation indicates support for Ev5, Dv5 and Lv3 SKUs but on the Azure portal itself only Ev4, Dv4 and Dv3 are supported- this is also true for CLI. Thus, we have given approcximate gen-on-on improvements for benchmarks of similar database workloads below such as for MySQL and PostgreSQL on D-v4 and E-v4 series of Azure instances when compared to older generation D-v3 and E-v3 Azure instances.
On MySQL™ Workloads, New Microsoft Azure Dv4 Virtual Machines with 2nd Gen Intel® Xeon® Scalable Processors Outperformed Dv3 VMs by up to 1.53x
Get 1.53x More MySQL Performance by Selecting Newer Microsoft Azure Edv4 Virtual Machines Featuring 2nd Gen Intel Xeon Scalable Processors
Handle up to 1.36x More PostgreSQL Database Transactions on Microsoft® Azure® Ddsv4 Virtual Machines vs. Dsv3 VMs

## This module deploys a Azure Managed Instance Cassandra datacter cluster in a user provided resource group, an existing vNET and an Subnet
#this is exampel for existing azure resource group and vnet
module "azure-acc-datacenter" {
source = "intel/azure-cassandra/intel"
acc_pswd = var.acc_pswd
resource_group_name = "DS-MANAGED-CASS"
acc_virtualnetwork = "dscassandra_vnet"
acc_virtualsubnet = "dscassandra_sub1"
tags = {
Owner = "user@company.com"
Duration = "24"
}
}
* **Prerequisites:**
1. Have an existing Azure Resource Group in the region you want to deploy the Azure Cassandra Datacenter Run Terraform
terraform init
terraform plan
terraform apply
Note that this example may create resources. Run terraform destroy when you don't need these resources anymore.
THREE IMPORTANT CONSIDERATIONS
- When using a Service Principal, it will require
Application.Read.AllorDirectory.Read.AllAzure AD API permissions see provider docs here - Make sure the
Azure Cosmos DBAzure AD application has not already been assigned theNetwork Contributorrole to the vnet as this will assign it - It takes 15-30 minutes for the Cassandra Cluster to be created and ready for use
