What are the advantages of cloud based Service?

Some of the advantages of cloud based services are:

Proven Web-services integration. By their very nature, cloud computing technology is much easier and quicker to integrate with your other enterprise applications (both traditional software and cloud computing infrastructure-based), whether third-party or homegrown. 

World-class service delivery: Cloud computing infrastructures offer much greater scalability, complete disaster recovery, and impressive uptime numbers.

No hardware or software to install: a 100% cloud computing infrastructure. The beauty of cloud computing technology is its simplicity... and in the fact that it requires significantly fewer capital expenditures to get up and running.

Faster and lower-risk deployment: You can get up and running in a fraction of the time with a
cloud computing infrastructure. No more waiting months or years and spending millions of dollars
before anyone gets to log into your new solution. Your cloud computing technology applications
are live in a matter of weeks or months, even with extensive customization or integration.

Support for deep customizations: Some IT professionals mistakenly think that cloud computing
technology is difficult or impossible to customize extensively, and therefore is not a good choice
for complex enterprises. The cloud computing infrastructure not only allows deep customization
and application configuration, it preserves all those customizations even during upgrades. And
even better, cloud computing technology is ideal for application development to support your
organization’s evolving needs.

Empowered business users: Cloud computing technology allows on-the-fly, point-and-click customization and report generation for business users, so IT doesn’t spend half its time making minor changes and running reports.

Automatic upgrades that don’t impact IT resources: Cloud computing infrastructures put an end
to a huge IT dilemma: If we upgrade to the latest-and-greatest version of the application, we’ll be
forced to spend time and resources (that we don’t have) to rebuild our customizations and
integrations. Cloud computing technology doesn’t force you to decide between upgrading and
preserving all your hard work, because those customizations and integrations are automatically
preserved during an upgrade.
