Is the technology of cloud computing PaaS platform complex? What technologies are used?

Platform-as-a-Service (PaaS) refers to the platform for software development as a service and submitted to users in SaaS mode. Therefore, PaaS is also an application of the SaaS model.

However, the advent of PaaS can speed up the development of SaaS, especially the development of SaaS applications. In 2007, domestic and foreign SaaS manufacturers successively launched their own PaaS platforms. PaaS can provide a middleware platform for enterprises to conduct customized R&D, covering databases and application servers.

PaaS can increase the number of resources utilized on a web platform. For example, you can use Data-As-a-Service (Data-as-a-Service) with a remote web service, you can use visual APIs, and even a PaaS platform like 800App allows you to mix and match other platforms that fit your application.

Users or vendors can quickly develop their own applications and products based on the PaaS platform. At the same time, the applications developed by the PaaS platform can better build enterprise applications based on SOA architecture.

The so-called PaaS actually refers to the submission of the software development platform as a service to users in the form of SaaS. Therefore, PaaS is also an application of the SaaS model. However, the advent of PaaS can speed up the development of SaaS, especially the development of SaaS applications.

The main reason why PaaS can promote the development of SaaS is that it can provide a middleware platform for enterprises to conduct customized research and development, covering databases and application servers. PaaS can increase the number of resources utilized on a web platform. Users or vendors can quickly develop their own applications and products based on the PaaS platform.

At the same time, the applications developed by the PaaS platform can better build enterprise applications based on SOA architecture. In addition, PaaS can help SaaS operators diversify and customize their products.

The easiest way: you can go to the UFIDA UU community to experience it for yourself, because the UFIDA UU community itself is a PaaS platform. This way you will be able to understand PaaS better!

platform-as-a-service

PaaS (platform-as-a-service: platform as a service) full name: (platform as a service) Chinese:

Platform-as-a-Service A business model that provides a server platform as a service. The service provided by the program over the network is called SaaS (Software as a Service), and the corresponding server platform or development environment provided as a service in the cloud computing era is called PaaS (Platform as a Service). Hope it helps.

AAS stands for as-a-service.

IaaS: -as-a-service

The first layer is called IaaS, sometimes called hardware-as-a-service.

PaaS: platform-as-a-service

The second layer is called PaaS, which is sometimes called middleware. All of your company's development can take place at this level, saving time and resources. PaaS companies offer a variety of solutions for developing and distributing applications, such as virtual servers and operating systems, on the web.

This saves you money on hardware and also makes it easier to collaborate between scattered studios. Web application management, application design, application web hosting, storage, security, and application development collaboration tools.

SaaS: The third layer of software-as-a-service is also known as SaaS. This layer is the layer that comes into contact with your daily life, and most of them are accessed through a web browser.

Any application on a remote server that can be run over the network is SaaS.

The services you consume are all from web pages such as Netflix, Mog, Google Apps, Dropbox or Apple's iCloud. Although these web services are used for both business and pleasure or both, they are also part of the cloud technology.

Hello, IaaS (InfrastructureasaService), i.e. Infrastructure as a Service. Consumers can access services from a well-developed computer infrastructure through the Internet. This type of service is called Infrastructure-as-a-Service.

Internet-based services, such as storage and databases, are part of IaaS. PaaS is an abbreviation for Platform-As-A-Service, which means Platform-as-a-Service. A business model that provides a server platform as a service.

The service provided by the program over the network is called SaaS (Software as a Service), and the corresponding server platform or development environment provided as a service in the cloud computing era is called PaaS (Platform as a Service). SaaS is the abbreviation of SOFTWARE-AS-A-SERVICE (Software as a Service), with the development of Internet technology and the maturity of application software, a completely innovative software application model began to emerge in the 21st century. It has a similar meaning to "on-demand software", theApplicationServiceProvider (ASP), and "HostedSoftware".

From the perspective of the technology stack structure of cloud computing, SaaS, as the application system link closest to the user layer, is undoubtedly an important part of the final processing of information and the output of value to end customers. Therefore, from the perspective of the final output value of users, SaaS is the "last mile" controlling factor of the overall cloud computing architecture, which needs to be paid more attention and investment.

However, on the other hand, whether SaaS meets customer needs is very important to whether the underlying architecture of related SaaS applications is solid enough to support the invocation of different API interfaces in upper-level applications and front-end development, in addition to the close cooperation of product, technology, testing, operation and maintenance functions based on customer needs in the relevant software integrated development team.

These calls to API interfaces are not only reflected in the richness of interface types, but also in the study of their computing power, and whether it is enough to consider whether the future users will be loosely coupled according to the different system priorities and service requirements corresponding to different stages in the development process, and these need to be fully considered at the level of IaaS infrastructure and the level of PaaS technology stack. For example, for the common digital delivery system, which is becoming more and more popular in large-scale projects such as petrochemical and other scenarios, and the volume of 3D models, attribute information, and documents that need to be supported in the application system is huge, then if the underlying server resources are insufficient to support it, and the functional components at the PaaS level are not adapted to the cloud computing architecture, it cannot support the specific development of upper-layer SaaS applications.

Judging from the country's attention to strategic resource projects such as "Eastern Data and Western Computing", as well as the fact that SaaS application systems and digital platforms still have a large number of functions that conform to business logic but cannot be realized by development, one of the key points is that the underlying resource cost of the corresponding functional application is too high. Whether the functional components of the PaaS layer are suitable for cloud computing and cutting-edge algorithms are constantly iterating. If the foundation is solid, the development space and service scenarios of SaaS will be more complete and rich in the future.

PaaS is short for Platform-as-a-Service in the field of cloud computing

As a programmer, Xiao Ming bought a domain name, a server, and developed his first ** and application, through which he benefited from the Internet. He develops the program himself and does the maintenance work (servers, domain names, security, etc.). After a few months, his server was attacked, and Xiao Ming lost important data.

After a period of restoration, he adopted Platform-as-a-Service (PaaS), outsourcing maintenance to PaaS and focusing on development himself. PaaS focuses on a portion of a development project, rather than the entire infrastructure. Infrastructure-as-a-Service (IaaS) solves the problem of purchasing and managing a data center, i.e., it provides computing resources on demand, such as:

Operating system, storage, etc. When Xiao Ming buys ** servers, there are 8G, 16G and other types to choose from, which is an infrastructure as a service (IaaS) for the virtual server industry.

However, platform as a service (PaaS) mainly solves the application operation and maintenance management, which originally requires an independent host (its own server) to build a server, and the server often crashes; Either you need shared hosting (web hosting), which often leads to competing for traffic resources, but Platform as a Service (PaaS) enables the power of standalone hosting and the ease of use of shared hosting, so developers don't have to be distracted by building and maintaining.

Both APaaS and IPAAS belong to the PaaS system, but there is a difference between them, APaaS tends to be between the beam of SaaS and PaaS, and IPAAS tends to be between IaaS and PaaS. The SaaS (Software as a Service) platform is for Oaks to deploy the application software on its own server, and even if the platform as a service (PaaS) builds applications, it is also with the help of the PaaS platform, without deploying its own server.
