Amazon EC2

Amazon EC2 offers several pricing models to cater to different usage patterns and budget requirements. The On-Demand pricing model allows users to pay for computer capacity by the hour or second without any upfront commitments, making it ideal for short-term, spiky, or unpredictable workloads. Reserved Instances provide significant cost savings of up to 72% in exchange for a one- or three-year commitment. Spot Instances offer the deepest discounts, up to 90% off On-Demand prices, by utilizing unused EC2 capacity, though they come with the risk of interruption. Savings Plans provide flexible pricing with up to 72% savings by committing to a consistent amount of usage over one or three years. Dedicated Hosts offer physical servers dedicated to a single customer, providing cost savings and compliance benefits. Additionally, EC2 includes a Free Tier that offers 750 hours (about 1 month) of t2. micro or t3.micro instances per month for one year.
