• All resources will be stopped when the budget is hit.

Answer explanation

Budgets in Cost Management help you plan for and drive organizational accountability. They help you inform others about their spending to proactively manage costs, and to monitor how spending progresses over time. You can configure alerts based on your actual cost or forecasted cost to ensure that your spend is within your organizational spend limit. When the budget thresholds you've created are exceeded, only notifications are triggered. None of your resources are affected and your consumption isn't stopped. You can use budgets to compare and track spending as you analyze costs.<br/>See: https://docs.microsoft.com/en-us/azure/cost-management-billing/costs/tutorial-acm-create-budgets

What is the best criteria to decide what resources go into the same resource group?

• Only resources from the same region should be in the resource group from that region.

• All resources of the same type (storage, virtual machines, databases, etc) go into their own resource group.

• Each resource should get its own resource group.

Answer explanation

A resource group is a container that holds related resources for an Azure solution. The resource group can include all the resources for the solution, or only those resources that you want to manage as a group. You decide how you want to allocate resources to resource groups based on what makes the most sense for your organization. Generally, add resources that share the same lifecycle to the same resource group so you can easily deploy, update, and delete them as a group.<br/>See: https://docs.microsoft.com/en-us/azure/azure-resource-manager/management/manage-resource-groups-portal
