One popular cloud infrastructure provider is Amazon EC2. EC2 is basically a pay-as-you-go datacenter. You pay for CPU, storage, and network resources. Using the open-source Infinispan data grid, you have a good chance of linear performance as your application needs change. Using EC2, you can instantly bring on hosts to support that need. Great match, right? What's next?
Assuming your data is important, you will need to persist your Infinispan cluster somewhere. That said, Amazon charges you for traffic that goes in and out of their network... this could get expensive. So, the next bit is controlling these costs.
Amazon offers a storage service called S3. Transferring data between EC2 and S3 is free; you only pay for data parking. In short, there is a way to control these I/O costs: S3.
Infinispan will save your cluster to S3 when configured with its high-performance JClouds plug-in. You specify the S3 Bucket and your AWS credentials and Infinispan does the rest.
In summary, not only does Infinispan shred your license costs, but we also help cut your persistence costs, too!
So, go ahead: Keep it in the cloud!
