- Elastic Map Reduce – uses Hadoop and EC2 instance type of your choice. In addition to the EC2 instance price and the storage price, you also need to pay for Elastic Map Reduce for each instance, which can be between USD 0.015 per hour to 0.42 per hour.
- Virtual Private Cloud – lets you provision a private, isolated section where you can launch AWS resources in a virtual network that you define

More Manageability Option
Auto Scaling – It allows you to scale your capacity up or down automatically according to conditions you define. For example, you can ensure that the number of Amazon EC2 instances you’re using increases during demand spikes and decreases during demand lulls. It is enabled by Amazon CloudWatch and available at no additional charge beyond Amazon CloudWatch fees.
CloudWatch – It provides monitoring for AWS cloud resources and the applications customers run on AWS. Developers and system administrators can use it to collect metrics and monitors resources. Basic Monitoring metrics (at five-minute frequency) for Amazon EC2 instances are free of charge, as are all metrics for Amazon EBS volumes, Elastic Load Balancers, and Amazon RDS DB instances. New and existing customers also receive 10 metrics (applicable to Detailed Monitoring for Amazon EC2 instances or Custom Metrics), 10 alarms, and 1 million API requests each month at no additional charge. Detailed monitoring is charged.
