- Security
Amazon Elastic Cloud Computing (EC2)
Elastic cloud computing is one of the most popular of AWS offerings. EC2 is a web service that provides servers in the cloud which are customized as per need. EC2 allows you to quickly boot a new server as and when needed or terminate it when requirement changes. It is highly scalable and works on a pay-as-you-go model.

- Renting virtual machine
- Storing virtual machine
- Distributing load across machines
- Scaling the services using an auto-scaling group
- Knowing EC2 is fundamental to understand the working of the cloud.
Benefits of EC2:
- Elastic web services computing
- Flexible
- Reliable
- Highly secure
- Cost effective/Inexpensive
Amazon EC2 Pricing:
- On-demand: On-demand instances let you pay for compute capacity by the hour or second (minimum of 60 seconds) with no long-term commitments. It can be purchased as a reservation for up to 70% off on demand price.
- Reserved: It can provide a capacity reservation. Discount (Up to 70%) compared to On demand instance pricing. They are 3 types of RI - Standard, Convertible and Scheduled.

Amazon Simple Storage System (S3)
Amazon simple storage system provides object storage which is built for storing and recovering any amount of data from anywhere over the internet
- Provides at-most Durability-99.99%
- Highly available (Availibility-99.99%)
- Cost effective
- Highly scalable
