Incremental Scaling on Azure

This section provides information on how to scale your deployment with Azure.

VM Sizing for VMware Telco Cloud Service Assurance


Footprint	VMs	Total vCPU	Total RAM (GBs)
25 K	9	16	64
50 K	13	16	64
75 K	16	16	64
100 K	18	16	64
125 K	21	16	64
150 K	24	16	64
175 K	27	16	64
200 K	30	16	64

Scaling from 25 K to 100 K

Scale the number of nodes in your cluster according to the footprint. The following snippet shows a sample example. For more information on how to scale the nodes for your AKS cluster, see the AKS documentation.
```
az aks scale --resource-group <your Resource-Group> --name <name of cluster> --node-count <number_of_vms> --nodepool-name <name of nodepool>
 
Example:
az aks scale --resource-group rg-vmw-us-west --name tcsa-cluster --node-count 18 --nodepool-name nodepool1
```
Note: The <number_of_vms> parameter refers to the number of VMs in the destination footprint of the workload cluster. In the example, number of VMs is 18 because the destination footprint is 100 K.

To scale the VMware Telco Cloud Service Assurance in your cluster from the Deployment Container, perform the following steps:

Navigate to the deploy.settings file inside the VMware Telco Cloud Service Assurance deployer package.

cd tcx-deployer/scripts/deployment
 
ls -lrt
total 88
-r-xr-xr-x 1 root root  6696 May  1   utils.sh
-r-xr-xr-x 1 root root  6844 May  1   uninstall
-r-xr-xr-x 1 root root  6148 May  1   tcx_app_deployment.sh
-r-xr-xr-x 1 root root   215 May  1   resize_lv.sh
drwxr-xr-x 3 root root   197 May  1   m3a_demo
-r-xr-xr-x 1 root root  6437 May  1   install-kubernetes.sh
-r-xr-xr-x 1 root root   454 May  1   install-govc
-r-xr-xr-x 1 root root  4511 May  1   footprint.json
-r-xr-xr-x 1 root root 30363 May  1   deploy-vms.sh
-r-xr-xr-x 1 root root  3796 May  1   deploy-vms.settings
-r-xr-xr-x 1 root root  2185 May  1   deploy.settings
 
vi deploy.settings

Set the FOOTPRINT under Product Helm Config to the footprint you want to upgrade to.
```
# Product helm config
FOOTPRINT=100k
```

Set the DEPLOYMENT_ACTION to deploy-apps under Deployment modes and actions and then Save and Exit the deploy.settings file.

# ========= Deployment modes and actions ========== #
# Options are "init", "deploy-apps", "deploy-all" or "cleanup"
DEPLOYMENT_ACTION="deploy-apps"

Run the tcx_app_deployment script.
```
./tcx_app_deployment.sh
```

Scaling from 125 K to 150 K

Scale the number of nodes in your cluster according to the footprint. The following snippet shows a sample example. For more information on how to scale the nodes for your AKS cluster, see the AKS documentation.

az aks scale --resource-group <your Resource-Group> --name <name of cluster> --node-count <number_of_vms> --nodepool-name <name of nodepool>
 
Example:
az aks scale --resource-group rg-vmw-us-west --name tcsa-cluster --node-count 24 --nodepool-name nodepool1
