Cloud : Dive-in
Cloud Computing refers to the delivery of computing and storage capacity as a service to a heterogeneous community of end-recipients. -wikipedia
So what actually is Cloud.Is it a buzzword or is it a new technology?
No. Its not a mere buzzword. Its the technology capable of changing the way traditional computing takes place.
To fully appreciate the implications of cloud,first we need to understand the traditional IT models followed in most companies.
Just a look at Dilbert:
So I hope we all infer the same patterns:
- The company buys “standard” hardware and it is expected of each employee to use such “standard” desktops,printers and storage.
- The company spends a lot of money on these “standard” hardware.
- All IT hardware need up gradation / replacement after certain time.
- Replacing or Upgrading is not a trivial task.It takes ‘months’ to happen.
Lets discuss each of the above points:
#1: The company buys “standard” hardware and it is expected of each employee to use such “standard” desktops,printers and storage.
Big companies generally buy bulk infrastructures and each employee is given an instance of it.This leads to a situation where the employee is expected to use the infrastructure provided by the IT Support.In the current times the market is full of a plethora of gadgets: Notebooks,iPads,Tablets etc.
Why should there be a restriction on what the employee should work ??? Its a matter of personal choice,but not possible in the traditional model of IT.
#2: The company spends a lot of money on these “standard” hardware.
The hardware available are not-at-all cheap.Among the biggest cost these companies incur is because of the huge datacenters they have to build.
The cost of servers,racks,cooling systems in the datacenters,maintenance and regular upgradation are by all means the cost of worry for the Finance department of each company.
#3: All IT hardware need upgradation / replacement after certain time.
Technology changes at a rate faster than we anticipate.Yesterday the RAM of personal computers was MB, now its GB and soon will be TB.
Systems become outdated and inefficient.Need Replacement.
#4: Replacing or Upgrading is not a trivial task.It takes ‘months’ to happen.
In the highly competitive world in which live “Time is Money”. Minutes of downtime cause stir in product teams.Long intervals of reduced productivity cannot be tolerated by companies who wish to move forward.
Can Cloud Computing help????
