Compute optimized instances
Compute optimized instances are ideal for compute-bound applications that benefit from high-performance processors, such as batch processing workloads and media transcoding.
Storage optimized instances
Storage optimized instances are designed for workloads that require high, sequential read and write access to very large data sets on local storage. They are optimized to deliver tens of thousands of low-latency, random I/O operations per second (IOPS) to applications.
Memory optimized instances
Memory optimized instances are designed to deliver fast performance for workloads that process large data sets in memory, which is quite different from handling high read and write capacity on local storage.
General purpose instances
General purpose instances are the most basic type of instances. They provide a balance of compute, memory, and networking resources, and can be used for a variety of workloads. Since you are requiring higher read and write capacity, storage optimized instances should be selected instead.
Cross-Origin Resource Sharing
Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell browsers to give a web application running at one origin, access to selected resources from a different origin. A web application executes a cross-origin HTTP request when it requests a resource that has a different origin (domain, protocol, or port) from its own.
