When the world of ICT is focusing on Cloud computing. I feel the full potential of the cloud computing is going to be realised when we combine all Infrastrcuture as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). The idea of combining these three services based on the reason that each one of the service having its limitation which overcome by the other service to the end customer.
As mainly the cloud services are offered to the small medium business and individuals. This article will be based on IT service requirements on small and medium enterprises. This is also another way of mass IT outsourcing.
Lets see the existing cloud computing services and their shorfalls to an Small and Medium Business IT.
- IaaS, which only provides the basic computing resources (cpu, memory & storage) on cloud. This provides advantages of having computing resources optimised and available on demand, Here customer still need to build and maintain entire IT application portfolio internally.
- SaaS, which only provides pre built packages on cloud. Here customer still need to maintain different other applications, integrations and infrastructure by themselves.
- PaaS, which provides platform where the developers can customise the specific customer needs. But customer has to develop themselves all the applications and integrations needed.
The consolidation in the Cloud computing is the future of ITaaS:
Following is my personal view of how the could computing consolidation makes a true ITaaS in future.
1. SaaS applications to include a PaaS along with for potential customization on the SaaS application for any specific customer.
2. PaaS to include the System Integration / Application Developer service (Please refer my previous post on HSaaS).
3. Now all these SaaS+PaaS hosted in a IaaS environment along with AD/SI service makes complete ITaaS for any small and medium enterprises.
4. There is one part left out, which is the workspace technologies like desktop, laptop, mobile,
multifunction devices and telephony. These all can be outsourced seperately until the dedicated
workspace / cube concept dies in future.
Lets consider the following box is which shows the whole Information Technologies needed in any company.
Where except the box marked blue all the other boxes can be offered on cloud as and which can be called true ITaaS.
It will be of a massive effort and it is not going to be revolution. I feel it will be a slow evoluation but the IT / Telecom industry will be reaching there. It will be a joint effort from a IT service provider and Communication service provider, basically an ICT provider.
