Cloud computing is the use of computing resources that are delivered as a service over a network, typically the Internet, and cloud providers manage the infrastructure and platforms on which the applications run. This allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at a remote location.
Software as a Service (SaaS) model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. The cloud users do not manage the cloud infrastructure and platform on which the application is running. This eliminates the need to install and run the application on the cloud user's own computers simplifying maintenance and support. What makes a cloud application different from other applications is its scalability. This can be achieved by cloning tasks onto multiple virtual machines at run-time to meet the changing work demand.
Cloud is all about scale, automated work flows, fulfillment assurance, cost efficiency and knowledge in various technical and business domains.

By using RFID, the universal issues of barcoding may be addressed for advanced automated systems. These include:
Requirement for line of sight readability of barcodes
Limited storage ability of a barcode
Limited application methods of barcodes on certain assets (eg bearings, tools and spare parts).
Passive RFID solutions allow minimal cost of RFID infrastructure as the RFID tags (or transponders) do not require an internal battery. The RFID tags are energised by the eletro-magnetic field energising the tag which is powered by the passive RFID reader. Passive RFID tags can only be read with passive RFID readers from distances up to 10 meters away.
Active RFID solutions are targetted to improve read distance and accuracy whilst also permitting for telemetry inputs for sensory systems. Such telemetry inputs may include temperature, humidity, shock, door open and sonsors.
