I’ve worked with tools like AWS Cost Explorer, Azure Cost Management, and Google Cloud Cost Management. I’ve also used third-party platforms like CloudHealth and Apptio Cloudability. My experience includes creating cost reports, setting budgets, and analyzing cost trends.

Question 6

What is a reserved instance (RI) and how can it help reduce cloud costs?
Answer:
A reserved instance is a commitment to use a specific amount of cloud resources for a set period, typically one or three years. In return, you receive a significant discount compared to on-demand pricing. This can significantly lower costs for predictable workloads.

Question 7

What are committed use discounts (CUDs) and how do they differ from reserved instances?
Answer:
Committed use discounts are similar to reserved instances but are offered by Google Cloud. Both provide discounted rates for committing to a certain level of resource usage. The main difference is the specific terminology and some platform-specific features.

Question 8

Explain the concept of cloud cost allocation.
Answer:
Cloud cost allocation involves assigning cloud costs to specific departments, teams, projects, or applications. This allows for better accountability and visibility into how cloud resources are being used. Tagging resources is a crucial component of cost allocation.

Question 9

How do you implement a cost allocation strategy using tags?
Answer:
I would work with stakeholders to define a tagging taxonomy that aligns with the organization’s cost allocation needs. Then, I’d ensure all cloud resources are consistently tagged. Finally, I’d use cost management tools to generate reports based on these tags.

Question 10

What is a cloud budget and how would you set one up?

Answer:
I’ve used IaC tools like Terraform and CloudFormation to automate the provisioning and management of cloud resources. IaC enables me to enforce cost-saving policies by automating resource configuration and preventing over-provisioning.

Question 13

What is auto-scaling and how can it help optimize cloud costs?
Answer:
Auto-scaling automatically adjusts the number of cloud resources based on demand. This ensures that you only pay for the resources you need. By scaling down during periods of low demand, you can significantly reduce cloud costs.

Question 14

Explain the difference between on-demand, reserved, and spot instances.
Answer:
On-demand instances are pay-as-you-go, offering flexibility but at a higher cost. Reserved instances provide discounted rates for committing to long-term usage. Spot instances offer the highest discounts but can be interrupted with little notice.

Question 15

How would you choose the right instance type for a specific workload?
Answer:
I would consider factors like CPU, memory, storage, and network requirements. I’d also analyze historical usage data to understand the workload’s resource consumption patterns. Then, I’d select an instance type that meets the performance requirements while minimizing costs.

Question 16

What is serverless computing and how can it contribute to cost savings?
Answer:
Serverless computing allows you to run code without managing servers. You only pay for the compute time you consume, which can lead to significant cost savings compared to traditional virtual machines. It is ideal for event-driven applications.

Question 17

Describe your experience with containerization technologies like Docker and Kubernetes.
Answer:
I’ve used Docker to package applications into containers and Kubernetes to orchestrate and manage those containers. These technologies enable efficient resource utilization and can help reduce cloud costs by optimizing application deployments.

Question 18

How would you optimize the cost of data storage in the cloud?
Answer:
I would use tiered storage options, moving infrequently accessed data to lower-cost storage classes. I’d also implement data lifecycle policies to automatically delete or archive old data. Furthermore, I would compress data to reduce storage footprint.
