  • [AWS CCP] 45, AWS Pricing Models
    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:
    - On-Demand pricing is the most flexible and expensive option, ideal for unpredictable workloads.
