Check the data retrieval systems put in place. This is not only in terms of the ease of recalling data through different mediums, but also with regard to recovery of data in case the hosting service changes their rules or has been acquired by another company. You have to be sure that you are getting things right.
You can find that certain plugins won't work due to memory issues, servers can fail due to the host's incompetence often causing a loss in Google rankings and sometimes WordPress's features won't work due to a poor host setup - so choosing a host not something to be hurried!
There is a green benefit to the cloud as well, fewer computers, better managed means less waste. If we all store our data in the cloud at data farms Cloudways which can run at efficiency or better instead of three different hard drives somewhere in our homes. There is a big savings on hard drives and energy use here if we use this right, never mind the wasted downtime of upgrades and moves.
Server Software: you may be used to certain server software, such as cPanel and Plesk in order to maintain your site. Some hosts use their own software which may be difficult to learn.
There is no fear of losing your valuable client data, due to network issues or overload of traffic. In a cloud hosting server, each server works in synch with the others, so that equilibrium can be maintained.Which in turn enhances the performance of the websites hosted over them, by allowing the sites to work here round the clock, without any interruption?
If you use Microsoft Outlook as your primary e-mail instead of the free Google e-mail client there is a sync applet for that too. A total of 20 minutes per person was used and we had a mail client that did everything we needed, or so we thought. Within a day I noticed my desktop wasn't getting its updates from my phone, and my phone wasn't getting updates from my desktop. The Google applet doesn't work with 64bit Vista. We had just upgraded half of our PC's for the 64 bit speed. Half of the office was working fine.
'Thumbsucking', as it is named somewhat weirdly, is the process where people can actually access the target machine physically. They can take the data out using portable storage devices like a flash device. This risk is hugely reduced if the cloud infrastructure is used. As most of the data will be in the cloud, physical access to one access point will not harm as much as it use to do in the existing system. But it also increases the second risk, known as HACKING!
