Description: The EC2 Spot Fleet is a collection of Amazon Elastic Compute Cloud (EC2) instances that allows users to manage and optimize the use of Spot instances, which are computing instances that can be acquired at significantly reduced prices compared to on-demand instances. These Spot instances take advantage of unused capacity in Amazon’s data centers, enabling users to access computing resources at a lower cost. The Spot Fleet simplifies the management of multiple Spot instances, allowing users to specify the amount of capacity they want and the maximum price they are willing to pay. This flexibility is crucial for applications that can tolerate interruptions, as Spot instances can be interrupted by Amazon if the market price exceeds the limit set by the user. The Spot Fleet also allows for the combination of Spot instances with on-demand and reserved instances, providing users with greater management and cost optimization capabilities. In summary, the EC2 Spot Fleet is a powerful tool for businesses and developers looking to maximize cost efficiency in their cloud computing operations.
