He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - Serverless means you don't provision or manage servers; AWS handles all underlying infrastructure management. - AWS Lambda is the core serverless compute service that runs code in response to events from over 200 AWS services. - The serverless pay-per-use model is most cost-effective for workloads with unpredictable or sporadic traffic. - A complete serverless architecture often includes Lambda (compute), API Gateway (APIs), DynamoDB (NoSQL database), and S3 (object storage). - A common exam scenario involves choosing between Lambda for event-driven tasks and EC2 for long-running, consistent workloads.

He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - Elasticity is about automatically adapting to variable demand, while scalability is about handling overall growth. - Horizontal scaling (adding more instances) is the preferred AWS method for achieving high availability and fault tolerance. - Vertical scaling (increasing instance size) is simpler but creates a single point of failure, making it a common exam distractor. - Elastic Load Balancing (ELB) distributes traffic, while Auto Scaling Groups (ASG) automatically add or remove instances. - Exam scenarios involving unpredictable traffic spikes are best solved with the combination of ELB and ASG for horizontal scaling.
