Question 1

What does a Cloud DevOps Engineer do?

Accepted Answer

A Cloud DevOps Engineer designs, builds, and maintains cloud infrastructure while automating software delivery pipelines. They bridge the gap between development and operations by implementing CI/CD, Infrastructure as Code (Terraform, CloudFormation), containerisation (Docker, Kubernetes), and monitoring solutions across platforms like AWS, Azure, and GCP to ensure applications are scalable, reliable, and secure.

Question 2

What is RAG (Retrieval Augmented Generation) and how is it used?

Accepted Answer

RAG (Retrieval Augmented Generation) is an AI architecture that combines large language models with external knowledge retrieval. Instead of relying solely on training data, RAG systems search a knowledge base (documents, databases, or APIs) at query time and feed relevant context to the LLM, producing more accurate, up-to-date, and verifiable responses. It is widely used for enterprise chatbots, customer support agents, and knowledge management systems.

Question 3

How can AI be integrated into existing cloud infrastructure?

Accepted Answer

AI can be integrated into existing cloud infrastructure through managed AI services (Azure OpenAI, AWS Bedrock, Google Vertex AI), API-based integrations, containerised model deployments on Kubernetes, and serverless functions that trigger AI processing. Key considerations include data pipeline design, model serving architecture, cost management, security, and observability. A Cloud DevOps Engineer ensures these AI components are deployed reliably with proper CI/CD, monitoring, and scaling.

Question 4

What certifications should a Cloud DevOps Engineer have?

Accepted Answer

Key certifications for a Cloud DevOps Engineer include AWS Certified Solutions Architect, Microsoft Certified: Azure Solutions Architect Expert, Microsoft Certified: DevOps Engineer Expert, Google Cloud Associate Cloud Engineer, and Microsoft Certified: Azure AI Engineer Associate. These certifications validate expertise in cloud architecture, automation, security, and AI integration across major cloud platforms.

Question 5

What is the difference between a DevOps Engineer and a Cloud Architect?

Accepted Answer

A Cloud Architect focuses on designing the overall cloud infrastructure — selecting services, defining architecture patterns, and ensuring scalability and security. A DevOps Engineer focuses on automating the delivery pipeline — CI/CD, Infrastructure as Code, monitoring, and operational efficiency. In practice, modern Cloud DevOps Engineers often combine both roles, designing infrastructure and automating its provisioning, deployment, and management end-to-end.
