AWS Certified Solutions Architect Associate (SAA-C03) - Dedicated Instances

The video tutorial explains the differences between dedicated instances and dedicated host instances in AWS EC2. It covers the configuration and cost aspects of dedicated instances, highlighting that they require explicit configuration and are not available in the free tier. The pros include hardware dedicated to the customer, which can address compliance issues and provide performance advantages. However, they offer less accurate licensing management compared to dedicated hosts. The tutorial also reviews AWS documentation and pricing, advising on decision-making for instance types based on performance and compliance needs.
