Hosting

Last week I noticed a lot of posts regarding pricing for Cloud hosting. Most of the authors states that this approach is more expensive in (1,5 - 5) times. As per me it’s reasonable since using virtualization means that hardware is shared and performance is less in comparison with managed hosting and private datacenter.

Here is my thoughts what hosting should be used and for what reasons:
1. Cloud – mostly applicable for startups. Low price for upfront investment, ability grow very quickly since adding new virtual machines are very easy thru API interface. Hosting expenses has less priority than getting more customers in short period of time.

2. Private Data-centers – Applicable for the solution if your operation team has experience for hosting similar SaaS products, Ops processes are established and you have clear vision how new system will be operated and loaded.

3. Managed Hosting – Same as above except – no huge upfront investment for hardware. Please note that managed hosting monitoring will cover monitoring of servers availability and does not cover application and services availability

As a conclusion – please select type of hosting carefully and take in to consideration whole Pros and Cons for your solution and look for one or two steps ahead in the future. Because you may lose a little now but get huge benefit in the future …
