Monitoring and surveillancing of large amounts of data is a matter of prime concern in the current scenario for major organisations as well as small-scale and large-scale industries. Presently, the increasing need to collect, analyse, and store the data in a real-time environment as well as ensure the qualitative and quantitative analysis of real-time data has become a challenge. In addition, traditional data acquisition and monitoring systems lead industries to face multiple constraints and limitations, which affect their functioning, such as physical infrastructure setup and cost constraints. In this chapter, the surveillance of various applications has been discussed. The chapter also focuses on use of cloud-based model to perform the real-time monitoring with the help of the web. The chapter deeply discusses the use of web for on-site and off-site monitoring of various industries and organizations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
