AWS, JavaScript, React - Deploy Web Apps on the Cloud - Characteristics of Cloud Computing (Part 3)

The video tutorial explains the concept of resource pooling in cloud services, where providers allocate resources to tenants using a multi-tenant model. It draws an analogy between cloud billing and utility billing in an apartment complex, emphasizing the need for accurate resource measurement. The concept of measured service is introduced, highlighting the importance of built-in tools for monitoring resource consumption. AWS is noted for offering a wide range of services. The NIST definition of measured service is provided, focusing on automatic control, optimization, and transparency in resource usage.
