Application service providers focused on hosting applications that otherwise would have to have been run in house by the customer. There were other, second level innovations that ASPs introduced such as subscription pricing for software licenses, but the core innovation was hosting business software.
Cloud computing incorporates these same changes, but also introduces several others, including:
1. The cloud can apply not just to the application layer, but other layers as well such as core infrastructure and computing resources.
2. Making IT resources available on demand so that companies can consume what they need when they need it is the core premise of the cloud.
3. Lower pricing is available via the cloud, particularly down at the infrastructure and platform levels.
4. The cloud leverages new software architectures that makes software available via the internet with no client side software/install/configuration required.
5. Cloud architectures also now incorporate true multi-tenant architectures.
6. Cloud computing has greatly reduced the amount of labor required to provision new customers and manage existing ones. This results in a direct benefit to the end user in the form of lower pricing.
In the 1990s, the big ASPs had their eyes on each of the aforementioned points. They just didn't get there.
Application hosting via ASP (application service provider) means provisioning of software or applications to companies and individuals via a network usually Internet. Cloud computing uses an advanced technology for hosting applications, etc. Cloud computing technology is characterized by on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. Cloud computing, the long-held dream of computing as a utility, has transformed a large part of the Information Technology industry, has made software even more attractive as a service, and has shaped a new way of deploying Information Technology hardware. Cloud computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). Some vendors use terms such as IaaS (Infrastructure as a Service) and PaaS (Platform as a Service) to describe their products. Cloud computing offers many benefits like fast accessibility via Internet, simultaneous accessibility for multiple users, scalability, rolling data backup, economical pricing, 24 by 7 support, etc.
