Moving e-mail and collaboration applications to the cloud will drive the first wave of adoption of cloud computing in the enterprise, which is still in its nascent phase. The enterprises still don't trust that they will be provided with the high service levels they would need to move applications onto large networks run by a small number of vendors. While vendors can claim they will be able to provide service level agreements (SLAs) for the cloud that users want, customers won't "really invest deeply" unless they have a trust relationship with vendors and can see for themselves. "The industry needs to mature a bit. Large enterprise customers don't really believe vendor SLAs," Ray Ozzie said at a JP Morgan event in Boston.
