Describe a complex cloud architecture solution you designed and implemented.

The applicant should provide details of their role in designing and implementing a sophisticated cloud architecture solution. Listen for mentions of the business needs fulfilled by the solution, automation strategies implemented, approaches to security and compliance, and the technologies used in support of the project. If necessary, prompt the candidate to describe any challenges encountered and how they overcame them. A response may reveal the cloud architect’s decision-making process, planning skills, and flexibility.

How do you approach cloud security and compliance in your designs?

Listen for answers that demonstrate the candidate’s thorough understanding of cloud security best practices, including specific encryption methods, regular security audits, network security measures, and data protection strategies. The applicant should mention and describe compliance standards like GDPR (for those in the EU) or HIPAA. They should elaborate on specific strategies or tools deployed for ensuring security in cloud environments, potentially offering examples of identity management systems.

Describe a time when you had to troubleshoot a critical issue in a cloud environment.

Ideally, responses should articulate the problem’s discovery, followed by the sequential steps taken to diagnose and resolve the issue. You may prompt for additional details like the specific tools used, processes implemented, and insights gathered. Responses will reveal an applicant’s problem-solving and analytical thinking skills. For example, to troubleshoot a networking issue in an EC2 instance, the candidate might suggest doing some or all of the following:

• Check whether security groups attached to the EC2 instance allow desired traffic.
• Check Network ACLs attached to the subnet where the EC2 instance is running to ensure correct rules are enforced.
• Check VPC resources such as NAT Gateway, Internet Gateway, and/or VPN.
• Use AWS tools and features such as CloudWatch Logs or VPC Flow Logs to investigate the issue.
• Use OS-level tools and configurations for debugging.

A candidate whose response covers all of these angles is likely well qualified to take ownership of such tasks.

How do you explain complex cloud concepts to nontechnical stakeholders?

If the position involves liaising with stakeholders or collaborating with external teams, seek out candidates who demonstrate the ability to communicate technical or complex ideas in simple terms. They should volunteer examples of instances where they’ve shared abstract information without the use of industry-specific jargon. For example, if a skilled cloud architect needs to explain to nontechnical stakeholders why a service such as Amazon S3 is necessary for a project, they might speak to the need for customers to securely access private proprietary files on demand; the need for the company to store these files reliably and ensure zero data-loss overtime; and how S3 makes it simple to implement this functionality with a user experience comparable to Google Drive. Such a response centers the needs of the users over the nuts-and-bolts engineering, demonstrating an ability to think about the big picture.

What steps would you take to ensure this company’s smooth migration to a cloud platform?

The candidate should outline a clear plan, starting with an assessment of the existing infrastructure. They should mention factors like resource allocation, network configurations, security and compliance protocols, and data management practices. If they do not have prior knowledge of the company’s business requirements, they should take the initiative and ask—or use historical data from a past or similar project. Next, the applicant should analyze the project’s parameters and select the ideal cloud platform that meets the needs identified. They should then design a migration strategy that ensures minimal disruption during the transition. This is a good question to ask to help gauge the candidate’s depth of experience with cloud migrations, especially at scale.
