Noisy Neighbor (cloud computing performance)

Noisy Neighbor (cloud computing performance) Noisy neighbor is a phrase used to describe a cloud computing infrastructure co-tenant that monopolizes bandwidth, disk I/O, CPU and other resources, and can negatively affect other users' cloud performance. The noisy neighbor effect causes other virtual machines and applications that share the infrastructure to suffer from uneven cloud network performance. The cloud is a multi-tenant environment, which means that a single architecture hosts...

Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to the needs and goals of a single organization. As a result, private cloud is best for businesses with dynamic or unpredictable computing needs that require direct...

pay-as-you-go cloud computing

pay-as-you-go cloud computing Pay-as-you-go cloud computing (PAYG cloud computing) is a payment method for cloud computing that charges based on usage. The practice is similar to that of utility bills, using only resources that are needed. One major benefit of the pay-as-you-go method is that there are no wasted resources, since users only pay for services procured, rather than provisioning for a certain amount of resources that may or may not be used. With traditional enterprise desig...

Platform as a Service (PaaS) Definition

Platform as a Service (PaaS) Definition Platform as a service (PaaS) is a cloud computing model in which a third-party provider delivers hardware and software tools -- usually those needed for application development -- to users over the internet. A PaaS provider hosts the hardware and software on its own infrastructure. As a result, PaaS frees users from having to install in-house hardware and software to develop or run a new application. PaaS architecture and how it works PaaS does no...
