, an internet performance engineering firm, helps companies achieve high availability, horizontal scalability and improved response times for mission-critical web-based business transactions and SOAP/REST Web Services.

In the past, outsourced virtual and physical instances of its Global Virtual Monitoring Appliance to multiple hosting vendors in order to replicate each customer’s slightly different platforms. The company needed to consolidate the effort to streamline deployment and lower the cost to deliver's service.

Today, the company uses a combination of Amazon Web Services and rPath technology to create, host and manage customer instances as Amazon Machine Images (AMI) on Amazon Elastic Compute Cloud (Amazon EC2). also uses Amazon Simple Storage Service (Amazon S3) to store individual, detailed probe results as *.xml files and Amazon Simple Queue Service (Amazon SQS) to support its alerting functionality.

“Amazon Web Services has become a key delivery component of the Global Web Monitoring framework,” says Chief Technical Officer John D’Esposito. “rPath enables us to deliver consistent and robust virtual and physical instances of our core technology for both web-based and private network deployments. Amazon EC2 empowers us to horizontally scale virtual monitoring instances with speed and at low cost whenever and wherever they’re needed around the world. The combined AWS and rPath solution enables us to reduce costs and improve development and delivery cycles by deploying and testing new images at will. We can implement fixes and features more quickly and with more confidence.”

Using AWS and rPath, can deploy a new virtual web monitoring instance within 5 minutes – a process which previously took hours or days. A newly deployed instance immediately provides processing power and scalability to the company’s core Web Monitoring service. Beyond the obvious benefit of flexibility and scalability, has achieved a cost savings of at least 20 percent per instance using Amazon EC2. By leveraging Amazon S3, Amazon EC2, and Amazon SQS, the company simplified its internally-managed environment, resulting in an estimated cost savings of approximately $100,000 per year.

“By combining the use of AWS and rPath, we have streamlined our deployments and dramatically lowered the cost to deliver our service globally. This advantage makes us more nimble, more completive, and able to provide a better service to our customers,” D’Esposito added. plans to begin using Amazon SimpleDB to take over data storage that does not require a traditional RDBMS system. The company also plans to leverage the newly announced Content Delivery Service to deliver unsecured content.
