Scheduling of real time tasks on clouds is one of the research problem, Where the matching of machines and completion time of the tasks are considered. Cloud computing is an internet-based computing, where resources, softwares and information are shared on demand basis i.e. The user can access documents anytime, anywhere. Real-time computer systems are required to produce correct results not only in their values but also in the times at which the results are produced known as timeliness. Here a quantitative expression of time is used to describe the behavior of the system. Real-time task...

The SaaS deployment is the installation to delivery of software services in cloud computing infrastructure. SaaS deployment is initiated by a cloud service provider via a user requesting process, which is generally automated. SaaS is a combination of different type of components; application component, integration component, business component, and storage component. Component placement problem (CPP) concerns with finding the optimum set of VMs on which SaaS components can be placed such that all user requirements should be satisfied and maximizes the profit of the SaaS...

These heuristic algorithms operate in two phases, selection of task from the task pool, followed by selection of cloud resource. A set of ten greedy heuristics for resource allocation using the greedy paradigm has been used, that operates in two stages. At each stage a particular input is selected through a selection procedure. Then a decision is made regarding the selected input, whether to include it into the partially constructed optimal solution. The selection procedure can be realized using a 2-phase heuristic. In particular, we have used 'FcfsRand', 'FcfsRr', 'FcfsMin', 'FcfsMax',...

Cloud computing is an encouraging and favorable paradigm for both providers and consumers in diverse scopes of endeavors. Software as a Service (SaaS) is a method of conveying services or applications through the Internet as a service, and it is known to be one of the very crucial computing services in cloud computing. Cloud computing has become a major medium for the SaaS providers to provide their applications so as to meet required scalability. The challenges of SaaS placement process depends on various factors comprising cloud network size, resource requirements, and communication among...
