The Solution
This consultancy was carried out by one of our Azure Technical Consultants. After familiarisation with the Azure tenancy, understanding the resources deployed, and the current configuration, a migration task list was created.
Stage one: Migration from PAYG to CSP
First, a Transparity-managed CSP subscription was deployed for the virtual machines and associated resources. After this due diligence was performed on the PAYG subscription to identify resources that could be moved and resources that needed to be rebuilt in the new CSP subscription.
Once this was carried out, we used Azure Resource Mover to move the resources to the CSP subscription. Transparity kept the customer engaged throughout this process due to the nature of their application and customers and ensured that the service remained fully operational during the migration. Transparity also deployed a new Recovery Services Vault to enable ASR used for Cross-Region replication to provide Disaster Recovery and to continue backing up the VMs.
Stage 2: West Europe Region Expansion
In order for Alphatec to successfully expand into this new region, we created a virtual network stack within West Europe, then another in North Europe for ASR Replication. Next, we deployed a Windows Server virtual machine as the application front-end and a Windows Server SQL virtual machine for the back end.
Following this we deployed a suitable patch management routine for both virtual machines and deployed a recovery services vault and established a backup routine. Lastly, a technical handover to Alphatec was done allowing them to now deploy the application components.
Stage 3: Virtual Machine Cost-Savings
We carried out a review of the environment and the biggest cost-saving available was to purchase Reserved Instances for the West Europe and UK South Virtual Machines and so these were ordered and applied. The next step for additional savings would be a move to an Azure Savings Plan.
Stage 4: Landing Zone Recommendations
Lastly, we reviewed the subscription and used automation to export all the Resources and provide an Azure Advisor-based assessment on low to high/medium-impact items that could pose a security risk or could provide a cost saving.
