What are the service models of cloud computing?
If you wish to make your career in network, the Certifications is considered to be the best certification, to jump-start your career. But gaining this certification isn’t considered to be that much easy. You have to go through lots and lots of study process unless you have the help of the 350–601 Dumps offered at the ITCertDumps.
The service model of cloud computing is divided into IaaS, PaaS, SaaS. These three modes represent three different levels, respectively. </ i>
Cloud service rating
IAAS (Infrastructure as a service, infrastructure, service) Layer
At this layer, the IT basic resource (computing, network, storage) is aggregated to form a resource pool by virtualization, dynamism.
The resource pool is a collection of computing power, and the end user (enterprise) can obtain its own computing resources through the network, run your own business system. This way users do not have to build these infrastructure themselves, but they can use these resources by paying.
For example, a few years ago If you want to run some business applications on the office or company website, you need to buy a server, or other price high hardware to control your local application, you can let you The business is working properly.
But now you can rent an off-site server, storage, and network hardware provided by IAAS. In this way, it greatly saves maintenance costs and office spaces.
above the Iaas layer is PaaS (Platform AS Service, Platform, Terrace Service) Layer
This layer provides basic computing power, It has an operational environment, providing IT components including application code, SDK, operating systems, and APIs for personal developers and businesses to embed the software or hardware to increase the development efficiency.
For business or end users, this layer of service can provide fast and low-cost environments for business innovations.
For example, PAAS provides various development and distribution applications on the Internet, such as virtual servers and operating systems. This saves the cost on hardware, making it easier to work between the dispersed studios. Web application management, application design, application virtual host, storage, security, and application development collaboration tools.
The uppermost layer is SaaS (Software AS Service, Software, Up Service) Layer
In fact, SaaS has existed before the cloud computing concept, And with the development of cloud computing technology has been better developed.
SaaS software is “used”, no user installation, software upgrade and maintenance also do not have to participate in end users. At the same time, it is still the software that is used on demand, and it is unparalleled than the traditional software.
Life, almost every day in contact SaaS cloud services, such as: We usually use mobile phone cloud services, some cloud services in the web page.
If we understand cloud computing into a building. This building is divided into top floor, middle, and low-rise blocks. Then we can understand the IAASS (Infrastructure), Pass, Sass (Software) into the three parts of this building.
where the infrastructure is in the middle, the platform is in the middle, the software is at the top.
Development Status of Cloud Services
Domestic cloud computing services have taken SaaS and IAAS in recent years, and PaaS is relatively small.
SaaS services occupy a half-wall of Jiangshan, the industry pattern is still more chaotic, lacks leaders;
PaaS service is still in the early days, the market recognition is relatively low, but The future growth is expected to be the highest;
IAAS service is more than 1/3, which has been fully recognized by domestic enterprise customers, cloud host, cloud storage and other application forms are the most used, accounting for More than 70%.
Saas’s future development trend is mainly in three aspects:
intelligent promotion process management efficiency increase : artificial intelligence and other technologies will be great Improve process optimization efficiency, improve service, become an important driving force for improvement of SaaS services.
Industry Vertical Saas Space Big : Accumulates a certain customer’s SaaS company in the vertical industry, there is an opportunity to explore other opportunities on the supply chain, such as B2B, value-added services, etc.
Cast fragmentation services : Most service providers focus on a single SAAS process and face the problem of service data mutually incompatible, so the SaaS service of the integrated fragmentation data and processes are provided. There is a chance.
At present, the status quo of the development of PaAS manufacturers is mainly based on the original technical function. According to the advantage to expand the service form and customer base, the expansion direction is mainly concentrated in the following three aspects:
< b> Expand service function : Expand from a single PaaS service into a variety of PaAS services to form a functional store.
Expand service form : Based on the original PaaS service, it expands the same class SaaS service.
expands new customers : Based on the PaAS General Module, provide customization process management for enterprises.
At present, the development trend of PaaS is mainly manifested in three aspects:
business type homogeneration: Provide a single function of PaaS vendors horizontally develop, growth For the PaaS tool store, it may cause the PaAS vendor’s business degree.
Developer value-added services become growth points: On the basis of providing functional modules, forming a platform ecology, providing technical services that meet the full process of enterprise / application lifecycle.
International business or new growth point: Technical modules are geographically located during the internationalization process, the usage habits are small, and the overseas market will become a new PAAS manufacturer. Growth point.
IAAS can be roughly divided into a germination phase, growth stage and shuffling stage.
Germination stage: In 2008, IBM established the first cloud computing center in China, marking IAAS officially entered China. One year, grand, Ali Cloud began research and development and pilot operation related cloud business.
Growth Stage: Before and after 2013, Microsoft, Amazon AWS IAAS business officially entered China. In the same year, UCLOUD, Qingyun and other IAAS entrepreneurship have begun to provide services, Tencent, Huawei and other giants have also joined cloud service camps.
Shipping stage: By 2015, the development of the IAAS cloud industry is stable, the industry pattern and profit model are getting clearer, and the industry leader begins, and the company gradually starts profit. At the same time, the industry competition has intensified and enters the shuffling stage.
Although no system is ever 100 percent protected, the ability for differentiating between typical network traffic as well as potentially harmful malware is considered crucial and provides the focus of this associate-level certification path. Also, if you wish to acquire this certification, you should gain the 350–701 Dumps, which are being offered at the ITCertDumps.
