5. Set budgets and alerts

Steps to optimize costs by reviewing resources, usage, and applying controls in Azure.

Process Table

Step	Action	Input/State	Output/Result	Notes
1	List all Azure resources	Azure subscription	List of resources with types and sizes	Gather data for cost analysis
2	Check usage and billing data	Resource list	Usage metrics and cost per resource	Understand where money is spent
3	Identify underused or idle resources	Usage data	List of resources with low or no usage	Targets for cost savings
4	Apply cost-saving measures	Idle resources list	Resources resized, shut down, or deleted	Reduce unnecessary costs
5	Set budgets and alerts	Cost data	Budgets and alerts configured	Prevent unexpected overspending
6	Monitor & adjust regularly	Budgets and usage	Updated cost reports and actions	Continuous cost control
7	Repeat process	Updated state	Ongoing cost optimization	Cost optimization is continuous

💡 Process repeats continuously to maintain cost efficiency

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	After Step 4	After Step 5	After Step 6	Final
Resource List	Empty	Populated with all resources	Same	Same	Updated (some removed or resized)	Same	Same	Same
Usage Data	Empty	Empty	Populated with usage metrics	Same	Same	Same	Updated	Updated
Idle Resources	Empty	Empty	Empty	Identified list	Same	Same	Same	Same
Budgets & Alerts	None	None	None	None	Configured	Same	Same	Same

Key Moments - 3 Insights

Why do we need to identify idle resources before applying cost-saving measures?

Because only idle or underused resources can be safely resized or removed to save costs, as shown in step 3 and 4 of the execution_table.

Why is monitoring and adjusting costs an ongoing process?

Cloud usage changes over time, so continuous monitoring (step 6) ensures cost controls stay effective and budgets are respected.

What is the purpose of setting budgets and alerts?

Budgets and alerts (step 5) help prevent unexpected overspending by notifying when costs approach limits.

Visual Quiz - 3 Questions

Look at the execution_table, at which step do we identify resources that are not being used effectively?

A Step 2

B Step 4

C Step 3

D Step 5

💡 Hint

Check the 'Identify underused or idle resources' action in the execution_table rows.

According to variable_tracker, when are budgets and alerts first configured?

A After Step 3

B After Step 5

C After Step 4

D After Step 6

💡 Hint

Look at the 'Budgets & Alerts' row and see when it changes from 'None' to 'Configured'.

If we skip step 4 (applying cost-saving measures), what will happen to the resource list in variable_tracker?

A It will remain unchanged after step 3

B It will be updated with resized resources

C It will be empty

D It will have more resources

💡 Hint

Step 4 is when resources are resized or removed; skipping it means no changes happen to the resource list.

Goal: Save money while keeping performance

Full Transcript

The Cost Optimization Pillar in Azure involves a continuous process. First, list all resources in your subscription. Then check their usage and billing data to understand spending. Identify resources that are idle or underused as candidates for cost savings. Apply cost-saving measures like resizing or deleting these resources. Set budgets and alerts to avoid overspending. Finally, monitor usage and costs regularly and repeat the process to maintain cost efficiency.

Practice

1. What is the main goal of the Cost optimization pillar in Azure cloud?

easy

A. To improve network speed only

B. To save money by using cloud resources wisely

C. To add more storage without limits

D. To increase the number of virtual machines

Solution

1. Step 1: Understand the purpose of cost optimization

   The cost optimization pillar focuses on managing cloud spending efficiently.

2. Step 2: Identify the correct goal

   Saving money by using resources wisely matches the cost optimization goal.

3. Final Answer:

   To save money by using cloud resources wisely -> Option B

4. Quick Check:

   Cost optimization = saving money [OK]

Hint: Cost optimization means saving money smartly [OK]

Common Mistakes:

• Thinking cost optimization means adding more resources
• Confusing cost optimization with performance only
• Assuming cost optimization ignores resource usage

2. Which Azure tool helps you monitor and control your cloud spending?

easy

A. Azure Cost Management

B. Azure DevOps

C. Azure Active Directory

D. Azure Monitor Logs

Solution

1. Step 1: Identify Azure tools related to cost

   Azure Cost Management is designed to track and manage cloud expenses.

2. Step 2: Exclude unrelated tools

   DevOps is for development, Active Directory for identity, Monitor Logs for diagnostics.

3. Final Answer:

   Azure Cost Management -> Option A

4. Quick Check:

   Cost Management = spending control [OK]

Hint: Cost Management tracks spending in Azure [OK]

Common Mistakes:

• Choosing Azure DevOps for cost tracking
• Confusing Azure Monitor Logs with cost tools
• Selecting Azure Active Directory by mistake

3. You have an Azure VM running 24/7 but only need it during business hours (8 AM to 6 PM). What is the best cost optimization action?

medium

A. Keep the VM running all the time

B. Resize the VM to a larger size

C. Schedule the VM to start and stop during business hours

D. Add more storage to the VM

Solution

1. Step 1: Analyze VM usage pattern

   The VM is needed only during business hours, so running it 24/7 wastes money.

2. Step 2: Choose cost-saving action

   Scheduling start/stop saves cost by not running VM when unused.

3. Final Answer:

   Schedule the VM to start and stop during business hours -> Option C

4. Quick Check:

   Stop unused VM times = save cost [OK]

Hint: Stop VMs when not needed to save money [OK]

Common Mistakes:

• Keeping VM always on wastes money
• Resizing larger increases cost
• Adding storage does not reduce cost

4. You see a recommendation from Azure Advisor to "Right-size your VMs" but your VM is already the smallest size. What should you do?

medium

A. Check if VM is underutilized and consider shutting down

B. Ignore the recommendation because VM is smallest

C. Upgrade VM to a larger size

D. Delete the VM immediately

Solution

1. Step 1: Understand "Right-size" recommendation

   It means adjusting VM size to match workload, avoiding waste.

2. Step 2: Since VM is smallest, check if it is needed at all

   If underutilized, shutting down or deleting saves cost.

3. Final Answer:

   Check if VM is underutilized and consider shutting down -> Option A

4. Quick Check:

   Right-size means match usage, not just smallest [OK]

Hint: Right-size means match workload, not just smallest size [OK]

Common Mistakes:

• Ignoring recommendations blindly
• Upgrading VM increases cost unnecessarily
• Deleting VM without checking usage

5. Your company wants to reduce Azure costs by using reserved instances. Which approach best fits cost optimization?

hard

A. Ignore reserved instances and focus on storage only

B. Use pay-as-you-go for all workloads to stay flexible

C. Always use the largest VM size available

D. Purchase reserved instances for steady workloads to get discounts

Solution

1. Step 1: Understand reserved instances

   Reserved instances offer discounts for long-term, steady usage.

2. Step 2: Match reserved instances to steady workloads

   This reduces cost compared to pay-as-you-go for predictable use.

3. Final Answer:

   Purchase reserved instances for steady workloads to get discounts -> Option D

4. Quick Check:

   Reserved instances = save on steady use [OK]

Hint: Reserved instances save money for steady workloads [OK]

Common Mistakes:

• Using pay-as-you-go for steady workloads wastes money
• Choosing largest VM size increases cost
• Ignoring reserved instances misses savings
