Description: Instance fleets in Amazon EC2 (Elastic Compute Cloud) are a feature that allows users to launch and manage a mix of different instance types and purchase options in a single operation. This means users can select instances from different families, sizes, and configurations, thereby optimizing the performance and cost of their applications. Instance fleets are particularly useful for workloads that require scalability and flexibility, as they allow users to adjust their computing resources based on demand. Additionally, they provide the option to use on-demand, reserved, or spot instances, offering greater cost-saving and efficiency in resource management. This functionality integrates with other cloud service features, such as auto-scaling and capacity management, facilitating the creation of more robust and adaptable cloud architectures. In summary, instance fleets are a powerful tool for optimizing cloud infrastructure, enabling businesses and developers to maximize performance while minimizing operational costs.
