Managing Risk in a Derivative IaaS Cloud
Infrastructure-as-a-Service (IaaS) cloud platforms rent computing resources with different cost and availability tradeoffs. For example, users may acquire virtual machines (VMs) in the spot market that are cheap, but can be unilaterally terminated by the cloud operator. Because of this revocation risk, spot servers have been conventionally used for delay and risk tolerant batch jobs. In this pa...
متن کاملA Method for Measuring Energy Consumption in IaaS Cloud
The ability to measure the energy consumed by cloud infrastructure is a crucial step towards the development of energy efficiency policies in the cloud infrastructure. There are hardware-based and software-based methods of measuring energy usage in cloud infrastructure. However, most hardware-based energy measurement methods measure the energy consumed system-wide - including the energy lost in...
متن کاملOptimal Autoscaling in the IaaS Cloud
An application provider leases resources (i.e., virtual machine instances) of variable configurations from a IaaS provider over some lease duration (typically one hour). The application provider (i.e., consumer) would like to minimize their cost while meeting all service level obligations (SLOs). The mechanism of adding and removing resources at runtime is referred to as autoscaling. The proces...
متن کاملEconomy Based Resource Allocation in IaaS Cloud
Infrastructure as a Service (IaaS) offers hardware resources (computing power, storage and network) as a service to its customers. The customers order these resources in the form of a lease. Aim of any service provider is to make a leasing plan to maximize the number of accepted leases. Opennebula is popular open source toolkit for building IaaS cloud. Opennebula has its own lease manager and i...
متن کاملA Novel Design to Increase Trust in Cloud IaaS model
In IaaS services of cloud the customers demand for hardware resources as a service like memory, processor cycles, disk storage even software. IaaS services of cloud rely heavily on virtualization. The service is provided by means of virtual machine. It is not easy task for cloud users to store their valuable data over cloud because of matter of trust over cloud. Data integrity in cloud environm...
