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...

Private Cloud (Internal Cloud or Corporate Cloud) Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a proprietary architecture. 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...

Cloud Orchestration (Cloud Orchestrator) Cloud orchestration is the use of programming technology to manage the interconnections and interactions among workloads on public and private cloud infrastructure. It connects automated tasks into a cohesive workflow to accomplish a goal, with permissions oversight and policy enforcement. Cloud orchestration is typically used to provision, deploy or start servers; acquire and assign storage capacity; manage networking; create VMs; and gain acce...

Cloud Service Provider (Cloud Provider) A cloud service provider, or CSP, is a company that offers some component of cloud computing -- typically infrastructure as a service (IaaS), software as a service (SaaS) or platform as a service (PaaS) -- to other businesses or individuals. Types of cloud service providers Customers will purchase an increasing variety of services from cloud service providers today. As mentioned above, the most common categories of cloud-based services include IaaS,...

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) 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...
