  • [AWS CCP] 8, Elasticity and Scalability

    [AWS CCP] 8, Elasticity and Scalability
    Mar 31 2026
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. 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.
