There has been a growing level of interest in the potential of SaaS (Software as a Service) as an alternative means of deployment for LIMS and ELNs. SaaS is an attractive option since it has the potential to simplify installation, deployment, and maintenance. Furthermore, is is globally accessible, and allegedly more affordable that a conventional managed, in-house approach. However, the question of security is the one that troubles most people since by definition, the vendor will be in control of the service and of your data. SaaS is the most common example of Cloud Computing, but despite the fact that the terms get used interchangeably, they are different. Cloud Computing, in a simple sense, is best considered to be the concept of using the internet to deliver software services, such as SaaS. Taking the laboratory into the cloud, or bringing the cloud to the laboratory, will be the subject of much debate, but the significance of the Cloud is unquestionable. It was the subject of ‘Google Atmosphere’ an event held in London on Oct 22nd, which interestingly included a presentation by Geoffrey Moore (best known for his book ‘Crossing the Chasm’ ). You can access the presentation here. It runs for 33mins, so get a beverage, and get comfortable.
