Customers must exercise caution when choosing providers.Market Definition/DescriptionCloud computing is a style of computing in which scalable and elastic IT-enabled capabilities are deliver

Cloud compute IaaS constitutes the largest segment of this market (the broader IaaS market also includes clou

Only cloud compute IaaS is evaluated in this Magic Quadrant; it does not cover cloud storage providers, platform as a service (PaaS) providers, software as a service (SaaS) providers, cloud service brokerages (CSBs) or any other type of cloud service provider, nor does
5、 it cover the hardware and software vendors that may be used to build cloud infrastructure. Furthermore, this Magic Quadrant is not an evaluation of the broad, generalized cloud computing strategies of the companies profiled.In the context of this Magic Quadrant, cloud compute IaaS (hereafter referr
6、ed to simply as “cloud IaaS“ or “IaaS“) is defined as a standardized, highly automated offering, where compute resources, complemented by storage and networking capabilities, are owned by a service provider and offered to the customer on demand. The resources are scalable and elastic in near real ti
7、me, and metered by use. Self-service interfaces are exposed directly to the customer, including a Web-based UI and an API. The resources may be single-tenant or multitenant, and hosted by the service provider or on-premises in the customers data center. (For more details, see “Technology Overview fo

The last category includes middleware and databases as a service, up

However, it does not include full stand-alone PaaS capabilities, such as application PaaS (aPaaS) and integration PaaS (iPaaS).We draw a distinction between cloud infrastructure as a service, and cloud infrastructure as a technology platform; we call the latter cl

In cloud IaaS, theThis research note is restricted to the personal use of This research note is restricted to the personal use of capabilities of a CESI are directly exposed to the customer through self-service. However, other services, including noncloud se

In this Magic Quadrant, we evaluate only cloud IaaS offerings; we do not evaluate cloud- enabled services. (For more on this distin

It encompasses both single-application workloads and “virtual data centers“ (VDCs) hosting many diverse workloads. It includes suitability for a wide range of application d

Most cloud IaaS is bought for Mode 2 agile IT, emphasizing developer productivity and business agility, but an increasing amount of cloud IaaS is being bought for Mode 1 traditional IT, with an emphasis on cost reduction, safety and security. This Magic Quadrant considers both sourcing patterns and their associated customer behaviors and requi
