A, IaaS, PaaS, SaaS and Comparative Introduction
With the influx of a number of new technologies, cloud computing, big data and artificial intelligence, enterprise information construction speed, cloud-based IaaS, PaaS, SaaS model three services occupy an important part of enterprise IT.
1. IaaS Introduction
IaaS is called infrastructure services, including processing CPU, memory, storage, networking and other basic computing resources. Based on IaaS service model, service can be provided to the consumer is the use of all computing infrastructure, provide for different user virtual environments, providing computing and storage capabilities, with data storage service, synchronization services, managed services and backup services Features.
IaaS advantage is that the consumer does not manage or control any cloud computing infrastructure, but it can control the selection of the operating system, storage, deployed applications, it is also possible to obtain a restricted network components (such as routers, firewalls, load balancers, etc.) control. On the operating costs, saving what hardware maintenance costs in two ways.
2. PaaS Introduction
PaaS can provide customized middleware platform for enterprise development, covering both the database and application servers. For example do technology development company, can provide customers what development language using the tools provided, for example, based on the current application development java \ php language, deploy the vendor's cloud computing infrastructure up, customers do not need to manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, etc., but customers can control application deployment is also possible to control the hosting environment configurations to run the application.
PaaS core services include content security services, directory services, bus services, workflow, authentication and shared services.
3. SaaS Introduction
SaaS services to help customers achieve interfacial accessed through a variety of clients on a variety of devices, such as the browser. Consumer does not manage or control any cloud computing infrastructure, including networks, servers, operating systems, storage, and so on.
SaaS provides software according to their needs for different users, and not need to be maintained, but also provides offline software and local data storage. Truly users can use software and services ordered anywhere. For enterprise technology research and development, software testing is very convenient.
4. Compare
If you are using IaaS services, it means you do not have to buy their own servers, and virtual machines Which just buy, but still needs its own server software installed
If you are using PaaS services, it means that you either need to buy a server, the server does not need to install their own software, you need only to develop their own program website
If you go further, buy some online forums and online store services, which means you do not have to develop their own website program, only you need to use them to develop a good program, and they will be responsible for upgrades, maintenance, such as adding servers and you only need to concentrate on operations, that is, for SaaS.
SaaS model is the ultimate user-oriented, and only need to concentrate on operations, regardless of everything on servers, software, program, is the most convenient and the most worry mode. SaaS model is definitely the future mainstream cloud market. Domestic SaaS model, most have great potential wave is PS cloud, imported from Europe, a very popular open source ERP
