Technical Knowledge & Experience

• 6. Can you explain the difference between AWS IaaS, PaaS, and SaaS?
  Answer: Infrastructure as a Service (IaaS) is the most basic type of cloud computing where the provider offers virtualized computing resources over the internet. Platform as a Service (PaaS) provides a platform for developers to create and deploy applications without managing infrastructure. Software as a Service (SaaS) delivers applications over the internet, eliminating the need to install and manage software locally.

  Answer: As an AWS Solution Architect, I am well-versed in security best practices and compliance measures in cloud environments. I regularly conduct security assessments, implement security controls, and monitor security logs to ensure the protection of data and compliance with regulations such as HIPAA and GDPR. I also stay updated with AWS's latest security updates and implement them in my solutions.
• 8. Can you explain the AWS Well-Architected Framework?
  Answer: The AWS Well-Architected Framework provides a set of best practices and design principles for creating reliable, secure, and performant systems on AWS. It consists of five pillars: Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimization. An AWS Solution Architect should follow these guidelines to design and implement robust and efficient cloud solutions.
• 9. How do you design for high availability and fault tolerance in AWS?
  Answer: To achieve high availability and fault tolerance in AWS, I use multiple Availability Zones, distribute resources across different physical locations, and implement auto-scaling for handling unexpected traffic spikes. I also rely on AWS services like Elastic Load Balancing and Amazon Route 53 for load balancing and DNS routing.
• 10. How do you deploy and manage containerized applications on AWS?
  Answer: I use Amazon Elastic Container Service (ECS) to deploy and manage containerized applications on AWS. ECS supports both Docker and Kubernetes and offers features such as task definitions, auto-scaling, and service discovery. I also leverage AWS Fargate to run containers serverlessly without managing infrastructure.
