Cloud computing allows for a lot of flexibility. Depending on the demand, you can increase how much of a cloud’s resources you use without the need for assigning specific hardware for the job. This technology also has increased the range of software applications, from data processing to voice and video communications, while lowering the cost of operating a more efficient business, as follows:
- Device and location independence enables users to access systems using a Web browser regardless of their location or what device they are using.
- Virtualization technology allows servers and storage devices to be shared and utilization be increased. Applications can be easily migrated from one physical server to another.
- Reliability is improved with multiple redundant sites that make cloud computing suitable for business continuity and disaster recovery.
- Scalability and Elasticity is accomplished via dynamic, near real-time "on-demand" provisioning of resources, without users having to engineer for peak loads.
- Performance is monitored, and consistent and loosely coupled architectures are constructed using web services as the system interface.
- Security in the cloud improves the ease of protecting information from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users.
- Maintenance of cloud computing applications is easier, because they do not need to be installed on each user's computer and can be accessed from different places.
