The rise of the enterprise IT problem (i)

The rise and fall of the IT in the enterprise


For one, Virtualisation enabled a better control over IT through software creation, manipulation and optimisation of IT resources. It improved its utilisation and reduced its cost as such.


At the same time, outsourcing proved that specialist companies can do IT better than the enterprise since IT is their core business. 

But, to efficiently outsource, we have to address  the issue of IT ownership since the IT depreciates at such a rapid rate today while its ineffective use increases massively its cost. And, after all, there is no much point in owning the IT given that the enterprise already outsources its hosting and management.

We also have to improve the interaction through self-service and direct online API access to outsourced services and the cost predictability with prepay and subscription like cost models. 


Last but not least, the Shadow IT proved that paying for the usage of an IT service supplied by a 3rd party would save them the cost to own and worry about each of the service IT components and their in house management and upgrades.


Then the Cloud came to the aid of IT.


The Cloud business model is the outsourcing of  the IT, both its ownership and management. 

To be effective, the Cloud employs IT virtualisation, without which it would not realise the economies of scale for multi-hosting and the ease of IT resources manoeuvring and optimisation.


It enables us to gradually move the IT outside the enterprise. The business model is IT renting rather than owning. It’s almost like leasing a car or a house rather than buying it.

We pay for the capability we use rather than for our over over-dimensioned systems that turn quickly obsolete and let us down because of improper management.


The Cloud offers today off the shelf IT infrastructure capabilities, standard enterprise applications, suites, platforms and specialised functions (calculations, big data…). It also provides, in a self service regime, on demand scalability, security, porting, availability (fault tolerance), backup, security and disaster recovery.
