Santa Clara, California - (The Hosting News) - July 31, 2008 - Web operations firm, OpSource, will provide online collaboration services for businesses, eXpresso Corporation's scalable Web delivery of secure collaborate services.

The company selected OpSource On-Demand because of its ability to manage its infrastructure while keeping pace with the volume of eXpresso users and their concurrent sessions.

eXpresso provides a complete and immediately usable Excel collaboration tool that requires no installation, support or training. However, with no in-house IT resources, eXpresso required a hosting solution that provided the technical aspects of its Software-as-a-Service (SaaS) offering, while also providing complete scalability to address the needs of its rapidly growing customer base.

George Langan, CEO of eXpresso, noted, ''In theory, the volume of eXpresso users can grow exponentially at any given moment, so we need an infrastructure that is dynamic, scalable and can stay ahead of our overall growth. We put OpSource On-Demand through a three-month pilot, during which time they not only provided us with the infrastructure and scalability we needed, but also demonstrated both a personal touch and an in-depth understanding of our needs and applications. We're now also evaluating OpSource Analytics to dissect data in a way that should enhance how it can be used by our sales team.''
