What service does Amazon EC2 provide?

Amazon EC2 (Elastic Compute Cloud) provides virtual servers, known as instances, that allow users to run applications through the cloud. One of the core features of EC2 is the ability to resize compute capacity on demand, which means that users can increase or decrease the resources allocated to their instances based on workload requirements.

This flexible capacity management enables users to quickly adapt to changing needs without the necessity of investing in physical hardware. It supports different instance types with varying amounts of CPU, memory, and storage options, allowing organizations to select the most appropriate configurations for their applications.

This dynamic scaling capability is particularly beneficial for businesses that experience fluctuating workloads, as it ensures they only pay for what they use while still having the capacity to handle peak demand efficiently.
