Hosting is becoming "Cloud" : The days of bare-metal servers are over.
The future of hosting will be 100% cloud, that is to say, RaaS (Resource as a Service) : a collection of services for renting resources (CPU, RAM, SSD, MSD) to be allocated to virtual instances within a multi-redundant and uninterruptible infrastructure.
In fact, when, for instance, you look closer at Amazon Web Services, you can see that not only it is already the case, but also that there is almost no reference to CPU frequency nor RAM speed anymore.
The idea is simple : a rent based on the consumption for the requests processing and the data storage.
So, the question is : is there some added-value left in such context for offering hosting solutions ?
Some software editors are taking advantage of the ease of virtualization : it allows them to offer SaaS (Software as a Service), which consists in re-selling instances with a custom configuration that perfectly suits a software stack along with a series of features to ease their management, while making a substantial profit (Office 265, WordPress.com or Odoo.sh are some examples).
But a collection of resources does not have the same value as a consistent infrastructure.
Indeed, despite an increased automation, some aspects are not covered and need a strategy that can be provided as additional services:
and some highly depend on the application layer:
Besides, web sites are no longer static: they're less and less "sites" and are becoming real Applications. And, in order to be Agile, an environment requires tools to guarantee its evolutivity and to control its costs:
technological developments monitoring to ensure
integration of tools to ease agility
