stage)
Provide support for the complete life cycle of business applications based on the network, including product design, Development, testing, deployment, production operation, etc. can also be called the basic software platform stage. However, when building middleware facilities on the basic cloud, you will find that the middleware cannot make good use of the various capabilities provided by cloud computing. To ensure that middleware services are highly reliable, available, and intelligent, there is a need to enable the middleware platform to make deep use of the various capabilities provided by the cloud platform.
The main features of this stage are:
(1) Provide unified middleware services, message services, integration services and other basic services to serve as
operation support for business software Platform
(2) The middleware can interact well with the underlying cloud computing and make better use of virtualization resources
(3) Provide a unified management platform that can realize the management of hardware resources and virtualization resources. , Unified management of middleware resources
(4) Realize unified allocation of hardware resources, virtualization resources, and middleware resources, and make more reasonable use of effective resources
3 , service cloud stage (service
cloud
stage)
Build various cloud services based on the platform cloud to directly provide business support to users. Since middleware is the direct supporting entity of the business system, business cloud services are built on the platform cloud and will be able to better provide available services to the outside world.
Main features:
(1) Business services are available on demand
(2) End devices can be customized to achieve different service combinations, and the same service can be used by different end devices
Ready for use
(3) Software services achieve socialization, intensification, and specialization
At present, most people’s understanding of the market is still in the first stage, and the direct goal is to save money.
In the second stage, some service developers will gradually increase their attention based on their in-depth understanding of cloud computing.
In the third stage, this stage uses the results of the paas stage. to dynamically allocate business service resources.
From the current point of view, it is mainly still in the stage of basic cloud construction. The core technologies are virtualization products and the provision of integrated management platforms and extended services for various industries.
