Ask the experts: Cloud Computing Questions Answeredby Johan De Gelas on March 28, 2011 7:25 AM EST
Question #1: Does Cloudsourcing Email Make Sense?
For SME’s (Small and Medium Enterprises) I would definitely advise against an on-premise (Exchange) mailserver. Not only is there the Capex cost of buying and the Opex cost of hosting the server, keeping Exchange operational requires quite a bit of expertise and patching. In other words, you’ll waste a lot of money on paying your administrator who has to divide his attention between the Exchange server(s) and many other IT tasks. E-mail must be about the most essential IT tool your employees have, so it is not wise to take any risk there.
I’ll focus on the two options I have experience with: a hosted version of Microsoft Exchange or Gmail for Business. Contrary to popular belief, Gmail for Business is quite different from the Gmail that we are all using. Gmail for Business is not datamined by Google, and no ads are displayed. It is also hosted on an infrastructure that offers higher availability and security than the regular Gmail. Costing only $50 per user per year for a 25 GB (!) , Gmail is easily two times less expensive than a hosted Exchange account with far less storage space.
The best argument against outsourcing e-mail to the cloud is also gone: Gmail for Business also comes with enterprise support. And Google also works with partners now, so you can get local support too. We are working together with Romneya for example, a Belgian Google Partner.
Support for mobile devices is pretty good: the blackberry enterprise server is supported very well and Gmail works – of course - fine with Android based mobile devices too. Google’s solution is also far superior when it comes to searching thousands of e-mails. For example, our exchange server still does not get that “Johan De Gelas” and “De Gelas Johan” are the same person. When searching, I am never sure I get all the mails I am looking for.
The only thing where I find our Exchange server to be slightly better is the scheduling events in calendar since the exchange server is integrated with the Active directory server.
Gmail is in my experience highly reliable. Gmail for business offers a 99.9% SLA, and I can’t remember any downtime since we started using it 2 years ago. No on-premise server can come even close, and even the hosted solutions can not offer this degree of availability.
So e-mail in cloud makes a lot of sense. It is much cheaper, easier, offers more storage, is more secure and reliable than any on-premise or hosted server. I am quite skeptical of some cloud services, but I can recommend placing your mailserver in the cloud.
