Dynamically Adding Virtual Network Rules to Azure Cognitive Account Using Terraform

 To enable access to various Azure resources via given virtual networks and subnets, we have to setup allowd subnets using virtual network rules in Azure resources. For example Azure Cognitive Account can be restricted to access only from given virtual networks and subnets. This requirement of allowed virtual networks and subnets may changed based on the deploying environment such as develop, qa or production. Let's look at how to write a terraform dynamic block to handle such scenarios, using Azure Cognitive Account virtual network rule as example, which can be used in other Azure resources as well.

Full sample code with  Azure Cognitive Account is available here in GitHub.

Business Rules for Work Items in Team Services

For inherited process model in VSTS, you can use Custom Rules to define rules that can clear the value of a field, copy a value into a field, and apply values based on dependencies between different fields' etc. You can define actions against conditions using custom rules. This provide you the flexibility in VSTS to go beyond the level of setting a default value or making a field required. To customize work items in an existing team project of Hosted XML model for VSTS, or on-premises TFS, you have to customize, downloaded process template or individual work item XML files (using witadmin tool) respectively. Differences between process models are described here.
