Yun "Yun" sentient beings Oracle and Salesforce controversy

Salesforce.com and Oracle have been "debating" about cloud computing, with the core of multi-tenant and virtualization technology.





saleforce.com and most SaaS vendors support multi-tenant technology-a technology architecture that employs a single software application instance to serve multiple customers.




"Multi-Tenant technology is the real future of our industry,"
Salesforce.com CEO Marc Benioff said in an Off-campus keynote speech. We can see its presence in the technology we use every day--twitter,facebook,google,netsuite, our company's salesforce,workday. All of the new companies you see are using multi-tenant technology to share the architecture. This is the most advanced and popular trend in all architectures. ”





Oracle is advancing in a different way by cautioning that multi-tenant technology is unsafe and outdated. Oracle is more in love with the cloud virtualization model, where each user's data can be placed in a separate database, running a stand-alone virtual machine environment.





while Multi-Tenant technology has received a majority of support for its very low management costs and costs, and even to reduce carbon emissions, Larry Ellison is still arguing in his OpenWorld keynote speech that it puts corporate data at risk.





Ellison said: "Multi-Tenant technology is a very bad security model that puts everyone's data in the same database." Although it is called multi-tenant technology, is actually 15 years ago the technical thinking, when Saleforce just set up. I mean, it's really the best technology I can do 15 years ago. ”





They keep your competitor's data together, it's really putting your data at risk.





Benioff countered that Multicomputer tenant technology had "quite a remarkable security history" and the conflicting views of the two sides continued to be debated repeatedly. Benioff points out that Facebook, the social media site, is the biggest example of the choice of multi-tenant technology.





Benioff said: "Virtualization is not the ultimate in the pursuit of efficiency, the real efficiency is multi-tenant technology, Facebook is proof." What kind of results can it deliver in a theory that gives all those customers a case-by-item? ”





multi-tenant technology: Safe?





that multi-tenant technology is a feature of some cloud computing is not accurate; Yefim Natis, a senior analyst at Gartner, believes that the problem with multi-tenant technology is not security but perception.





Natis said: "If you see a successful cloud platform, such as Salesforce, I do not believe that any well-known instances have been corrupted or attacked, at least as far as I know." To say that the sky is unsafe, this view is somewhat unreliable. ”





Gartner published a forecast last March that, for the entire 2012, 60% of virtualized servers are less secure than the physical servers they have just replaced. The main reason for the forecast is not the inherent problems of many tenants, but the fact that the system has not been properly implemented.




What is hidden behind the
Oracle cloud approach?





Natis also sees Oracle's new product, which has no multi-tenant technology and a vague timetable, and estimates at best a "hesitant public cloud".





Natis said: "The reason is that they would rather cloud services disappear altogether." This is my corollary, they do not really cloud. ”





with the acquisition of Sun Microsystems and the release of Exadata and Exalytics, Natis believes Oracle has become more like a hardware company. Although there are also public cloud products, Natis sees it as a response to "great pressure on what they do".




"They can't object to cloud computing,"
Natis said. They cannot continue to do so. "And by the end of the year, every well-known manufacturer will have PAAs (Platform-service) products."





Suppliers outside the PAAs market will begin to struggle in this area. IBM was the last to get involved in the war, and the company released SmartCloud earlier this month. While the market share debate may seem to add to their weight, it is true that big companies like Oracle and IBM are entering the field, and they are building their own public cloud.




"Another effect of Oracle is that users are becoming increasingly interested in public clouds for a variety of purposes, and they must have noticed that some of the company's customers are looking for cloud services and are considering alternatives,"
Natis said. ”





Beware of false cloud





Ellison in his OpenWorld conference keynote speech reiterated that Benioff let "beware false cloud" popularized.





While most PAAs providers in the debate are on the Benioff side, Oracle's public cloud is still in its infancy and little detail is known.





Natis said: "They tell you that you can run the same applications internally, or you can run them in their public cloud in the future, and I want to emphasize that in the future, in Java services." They didn't tell you that the Java service they run in the cloud is better in any way than it is now. They just said it was available and they didn't tell you it was excellent. ”





technology will not go away because of countless supporters and their market push. Oracle and others already in the field now face the challenge of demonstrating to users that there are many ways to work.
