As a benchmark service--paas platform for Cloud computing provides additional services for developers to integrate into their applications, the developer efficiency and application richness that can be achieved through PAAs is also considered one of the major trends in cloud computing.
But at the moment, cloud computing has grown somewhat misshapen at home, concentrating on more SaaS and IaaS, with few PAAs components. What's the reason?
In my opinion, the reason is that PAAs has gradually become Paas+iaas fusion. Because it not only provides a set of program development interfaces (APIs) and a set of execution time languages, enables developers or users to write programs on top of it, and it also contains the infrastructure that the service provider is responsible for provisioning and maintaining at the bottom, including virtualization, OS patching, scalability, automatic sizing, Security issues and so on.
For enterprise users, PAAs allows you to build more complex applications and infrastructures if you can use Java, C #, or other languages, and you don't have to manage your middleware, operating system, or infrastructure configuration yourself. PAAs Services can help you accomplish these tasks.
But for customers with large data capacity requirements and mission-critical applications, the services and products currently available to mainstream PAAs platforms are not fully satisfied. In a sense, the PAAs platform is not only the software stack, but also the hardware stack service under the platform, so the PAAs is the most attractive to enterprise users, but it is also the most difficult to use a cloud service.
Difficulties in the development of commercial PAAs platform
1, the first is the problem of mixed cloud model, at present, there is no platform to provide all the enterprise needs, enterprises in the choice of IT services, will inevitably face a mixed cloud solutions, and these solutions are often hosted by multiple branches or organizational units shared in the enterprise private cloud Or hosted in a mixed cloud in the case of local IT systems outsourcing or a complex supply chain.
2. Open questions: integration with current internal or external systems.
3, industry-specific IT standards, applications and services.
4, business model and the uncertainty involved in the role: there are a variety of user behavior models and system usage patterns of industry-specific user groups, such as workload curve, resource task requirements type and system capabilities.
5. Time to establish a solution: few companies have enough time to build a new IT infrastructure from scratch, which involves the rapid setting of the cloud environment, replacing the old system, and gaining business continuity with the current system integration. So the time to deploy and manage becomes a key factor in the hesitation of the PAAs solution under consideration.
6. Various applications and user types: A complete industry solution includes applications that are developed and owned by different user groups (independent users or organization users).
7. Most enterprise users are not IT professionals who are terrified of using complex programming models, such as java,web2.0 and Web services, to develop, deploy, and manage applications and systems.
8. Special business needs are driven by business stakeholders and customers, such as shorter time-to-market, support for business agility through rapid modification of process or business logic, and rapid expansion of enterprise systems.
9. In the long run, PAAs will likely replace IaaS as the most mainstream model of cloud computing. But whether it's Google App engine or salesforce.com, there are some proprietary APIs that make it inconvenient for users to migrate applications. At the same time in response to speed, Google App engine also have some deficiencies.
10, and the most critical point, whether it is azure, GAE (Google App Engine) or cloud Foundry, these foreign excellent enterprise-class PAAs platform, the biggest problem is that they can not really landing in the country, Internet services from abroad are becoming more and more stringent, which makes it impossible for domestic enterprise users to consider the problem of network regulation in their choice.
These are the core focus of the PAAs platform. And even if you make a good product, and you just serve the service, Google Gae is difficult to replicate because of this, the domestic who can make a real enterprise-level PAAs platform? Telecom, Huawei, Ufida or internet companies?
Domestic commercial PAAs platform, who can rise?
Telecom operators?
Moving the big cloud is very high-profile, but from the current point of view, in the big cloud established more than a year later, in addition to Pangu search has been built on the big cloud platform, there is no more enterprises to choose the big cloud platform. In fact, for telecom operators such as China Mobile, the benefits of PAAs can be built on the platform, control content providers, and then grasp the industrial chain, but its disadvantage is that too restrictive third-party supplier development capabilities, the standard open interface is bound to lose a part of CP/SP support. Insiders say that, "OPhone's example has proved that too much emphasis on dominance will weaken the enthusiasm of industry chain manufacturers", "to achieve these technical characteristics is not easy, the current several major software vendors proposed cloud Platform solutions are immature, China Mobile cloud platform to complete and operate I am afraid it will take some time. ”
Huawei, ZTE?
Technically, whether Huawei or ZTE, they have the strength to do PAAs platform, at the third cloud Computing conference, we also saw Huawei and ZTE's cloud computing solution. Li Sanqi has said that the current Huawei in the original operator business and terminal business, opened up a new area: business. In addition, Huawei is trying to create an open cloud computing platform that will open the standard interface to millions of developers worldwide and support them in developing a wide variety of cloud applications.
It should be said that, whether ZTE or Huawei, the establishment of PAAs platform is not the technical level, the core of cloud computing is open and shared, a large number of data and enterprise-level users need to achieve open sharing, so Huawei and ZTE can change the past behavior, this is the key issue.
Traditional software vendors?
You can see that in the enterprise-class user market, China's largest two management software manufacturers-Ufida and Kingdee is absolutely no lack of experience.
In just held the Ufida conference, Ufida Yang Yishong General manager said, Wai-ku is about to release the PAAs platform, and this PAAs platform will have 10,000 cloud services, 100,000 servers, million service customers, thousands of active customers.
Ufida group CTO Xue in an interview with the author said-"Ufida the biggest advantage lies in their understanding of enterprise users." Admittedly, this is definitely an advantage, but what they lack, the same is the Internet gene, and since Ufida has made it clear that it will not be involved in the field of IaaS, this may also be a potential future danger, after all, a successful commercial PAAs platform must be integrated IaaS.
Internet companies?
"Whether it is Sina or Tencent, at present, their platform can only be used as a platform for consumer-level business, business, I am afraid, is far from the point"-this is an industry veteran of the current domestic mainstream internet companies launched an open platform evaluation.
This evaluation is indeed relatively pertinent, domestic internet companies currently based on cloud computing applications are basically cloud storage. Of course, the establishment of the public cloud, in fact, storage is indeed the threshold of the bottom, because this is an expected logical-intensive public cloud products. And once up to the enterprise-level application level, especially the need to integrate with the business platform, from the current point of view, it seems difficult to find a decent platform.
Conclusion: Predictably, in the cloud industry chain, the future is in PAAs and IaaS two layer of enterprise monopoly will gradually strengthen, PAAs will also be an industrial chain of the commanding heights, it can control the core of the industry, whether it is Sina SAE, Baidu Bae, Sutra or Ufida PAAs platform, they are not perfect. At present, the domestic cloud industry is still in the process of development, which also requires a large number of industrial chain partners to work together to share technology, experience, in order to quickly promote the development of cloud computing, the real industry bigger and stronger.
