IT Infrastructures are complex. Maintaining them is definitely a rocket science. It is also not very inexpensive.

With IT technologies upgrading at phenomenal rate, staying updated with latest trends isn’t cheap and requires ongoing training and research.

Therefore the complexity of IT Infrastructure is increasing and companies have to have personnel who are equipped with right skills to manage them.

In Modern Organisations, IT is at the core of all departments of organization making IT an integral part of the organisation.

Now either these organisations keeps on maintaining the IT Infrastructure themselves or they can start opting the Cloud Computing Services which are fixing this pain area.

No longer companies have to invest millions of dollars in setting up IT Infrastructure on-premise as they can opt for all Cloud Based Software Solutions for their organization.

So what are the main advantages of Cloud Computing ?

• Reduced IT Department size
• Less expenditure on IT Infrastructure ( As per Microsoft, 89% of the IT Budget is spent on maintenance and infrastructure ).
• Reducing massively sub optimally used resources.
• Great Return on Investment
• Work force will spend more time on Company’s Line of business than struggling with the Infra.
• Flexibility of accessing the Cloud Applications across wide range of mobile devices and is not geographically constraint.
• Applications and Security updates are taken care of by the service provider.
• Increased Productivity
• Collaborative environment - since the application is internet dependant and is not geographically constrained, users can work together on the same application simultaneously.
  Per user costing. If you are a small enterprise, the pay per user costing will be very effective. You don’t have to spend millions of dollars on setting up the infrastructure as you can access the same application using internet in fraction of the cost.
• Upgrade the subscription as you grow.
• Don’t have to own technology to compete effectively.
• Owning all processes of IT burdens and hampers your growth. outsourcing it to specialists makes it more productive.

But there are skeptics who are arguing the advantages and following is their take:
Internet dependency - since internet is major dedepency, any major break down will completely cause downtime leading to massive losses. But statistically, chances of occurrence of this is very low.
redundancy is the key.
