Infrastructure as a Service
Thursday, September 24th, 2009
When AT8 formed 3 years ago we were often drawn into arguments about online systems versus offline systems. The truth was there was no one right approach as it depended upon the business model being supported. Today the argument has shifted subtly to whether SaaS (Software as a Service) solutions are suitable to today’s market or not.
To examine this argument further we first need to define SaaS solutions and to do this I turn to our old friend Wikipedia who state:
Software as a Service (SaaS, typically pronounced ‘sass’) is a model of software deployment whereby a provider licenses an application to customers for use as a service on demand. SaaS software vendors may host the application on their own web-servers or download the application to the consumer device, disabling it after use or after the on-demand contract expires.
In this definition it is important to note that this is not about online versus offline – both models can be supported in a SaaS environment (although it is usually online vendors that operate in this manner). It is also not about simply hosting solutions on behalf of vendors. It is licensing access to software as it is needed, scaling the usage (by users or transactions) as required.
The advantages of this approach can be substantial, especially when combined with an online philosophy. The end user doesn’t need to invest in servers and has reduced IT management overheads, the service and their associated costs can scale to their business requirements, the software is kept current and up to date, the business model is more cost effective to run, and so the list goes on.
There are more and more suppliers of SaaS solutions out there. Salesforce.com is one of the most notable brands but there are also several Insurance specialist brands including IntelliFlo, True Potential and Solution 4.
At AT8 we have also taken this philosophy in building our own office infrastructure. We use Salesforce.com for our contact management, our email services are run by 1&1, while our documents and managed and stored on a service called huddle. We don’t limit the approach to software and we also buy our telecoms in this manner using a virtual PBX from Voipfone. We don’t have the capacity or the desire to manage our own infrastructure especially as it is cost effective to get others to do this for us. It is in effect Infrastructure as a Service.
It is interesting to see that some third parties, such as the recently formed Cirrus ICT are now beginning to join all these different Infrastructures Services together as one package for distributors. They add to their offering an IT management service to help ensure that the services, especially those of a larger scale than our own, are smoothly implemented and provide a reliable an ongoing service.
As with the arguments we used to referee three years ago during the online vs offline debates, Online SaaS solutions will not be the right answer for everyone. Some, especially large Banks, will not want an external service to host the data, some may want offline access, others will simply get frustrated with the performance problems that can occasionally happen with these services. But SaaS is getting main stream support and should not be ruled out without careful consideration.
