Recent Advances in Autonomic Provisioning of Big Data Applications on Clouds
CLOUD computing [1] assembles large networks of virtualized ICT services such as hardware resources (such as CPU, storage, and network), software resources (such as databases, application servers, and web servers) and applications.In industry these services are referred to as infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Mainstream ICT powerhouses such as Amazon, HP, and IBM are heavily investing in the provision and support of public cloud infrastructure. Cloud computing is rapidly becoming a popular infrastructure of choice among all types of organisations. Despite some initial security concerns and technical issues, an increasing number of organisations have moved their applications and services in to “The Cloud”. These applications range from generic word processing software to online healthcare. The cloud system taps into the processing power of virtualized computers on the back end, thus significantly speeding up the application for the user, which just pays for the used services.
