Recently I got a question from a friend – what good will moving to cloud give me, will it save my money?
Maybe or maybe not – it depends and it depends on how you look at your money/time correlation.
Moving to cloud and thinking about saving money first of all is very wrong. Cloud gives you reliability, capacity, high-availability, performance, flexibility, mobility, seamless experience, newest versions of hardware/software… Cloud is your possibility to make your company work better and more efficient. For example, what about cross-continent high-availability? What about five "9" availability? What about new hardware that is being released every year? Can you afford the downtime caused by faulty software update? Think how much effort you would need to accomplish these complex things on your own and those are there, in cloud, ready to be used and deployed, just a few mouse clicks away.
Apart from that, moving to cloud means that you do not have to think about hardware or software maintenance, patch management (countless hours of pretesting included), new versions, updates and upgrades and so on. You always get the newest hardware, newest software and almost all the work is done there already for you, particularly if you choose SaaS and PaaS. That means that your IT team does not waste the valuable time to problem solving. Instead, they can focus on innovation, focus more on things that will move your company forward in much shorter timeframe.
As you are already thinking about cloud the correct way, we can say some words about saving money too. There are many cases when cloud costs less than on-premises. For example, when you need a SharePoint or SAP development environment for your developers – why pay money for licenses? Why pay for the hardware or someone to construct that complex environment for you? Instead, you can do that all in minutes – in cloud (Azure is a good example here).
Another good case is a new company – building your own, albeit even a small sized datacenter costs a lot of money. Often cloud is way cheaper for such cases.
If you already have existing infrastructure, cloud may be a great place for your backup datacenter – particularly when modern cloud providers charge only for the amount of resources you use (e.g. you do not pay a cent for a turned off VM in Azure, you pay just for storage).
The topic is huge and we can talk a lot about it but I hope I touched enough in this short post to emphasize some of the key elements of cloud.
So think about cloud, but please, the correct way
