But even when you pay "as you go" you want to have as small bill as possible. Today, I want to share with one trick used by my company MBTE Sweden AB (the company behind Bindows Framework and Groovy++ Programming Language) to minimize our expences on virtualized infrastructure.
Thechnically the article consist of two parts. The idea is based on choosing most optimal from three options to purchase computing power from Amazon EC2. There is one important trick about spot instancesWhen you purchase Spot Instance you bid for maximal price you are ready to pay per hour.

Amazon DynamoDB Object Mapper The DynamoDBMapper eliminates the need for application-level data conversions and custom middleware solutions by using Plain Old Java Objects (POJOs) to store and retrieve Amazon DynamoDB data. Amazon S3 Transfer Manager Through a simple API, the Amazon S3 TransferManager achieves enhanced throughput, performance, and reliability by making extensive use of multi-threaded Amazon S3 multipart uploads.

The cloud is an amazing thing, but one that is poorly understood.
Before I launch my rant, I'll qualify that SaaS existed before "the cloud," yet in many defintions (like the link above) it is considered a cloud service. The Cloud The cloud... what is it? Virtualization This simple provisioning is empowered by some sort of virtualization technology like Xen (likely one of the commercial implementations), VMWare, Solaris Containers (Zones), Virtuozzo/OpenVZ, etc.
