伦敦大学的研究人员表示,随着云计算市场的日趋成熟,服务水平和法律标准促使云服务供应商向个人用户和企业用户提供可定制的云服务,云服务供应商们开始寻找更加人性化的供应服务。

   目前的供应商想主要通过提供“一站式服务”来满足服务商所有商业要求,但是研究人员发现,这样并不能完全满足客户的需求。比如,一些垂直服务型企业:健康中心,政府和财政部门,每一个都需要一个合适本部门的系统要求然后才部署云计算服务。现在供应商刚刚开始提供定制云服务,不过这个趋势会不断加速发展下去。

   伦敦大学Queen Mary云计算法律项目的学术带头人,Christopher Millard说:“要想具有竞争优势,供应商们就不得不去考虑用户的需求,协商合作要更加灵活,更愿意去展示他们服务的安全性和稳定性”

   可定制云服务:社区云服务将成为下一个热点项目?

   经过项目组三年的研究发现,在云服务项目的合同中一下六项是最经常被商讨的:供应商的实力,服务水平协议,数据保护和安全,终止权,单边修改服务条款,知识产权。以为研究院说,以上六点也说明了用户在使用云服务过程中最关心的是什么。

  “公司普遍担心云端服务会成为泄漏公司信息的另一种机制,”Walden补充道,“BYOD加上基于云端的服务让CIO们和信息保卫人员担心公司会潜在的丢失公司数据”。供应商们刚开始意识的这一点,现在正提高服务打消公司的顾虑。

    研究人员还发现不同的供应商的SLAs是有区别的。例如,Amazon Web Services 提供99.95%的时间供用户正常使用和有效工作,而一些其它的云服务供应商提供高达99.999%的时间供用户正常使用。但是在这些供应商的服务中,供应商还没有针对个人用户提供可定制的云服务。

    OnApp公司向服务供应商提供云平台,其CMO Kosten Metreweli说到,SLAs和独特的服务使供应商各具特色,这对供应商和用户都有好处。例如,对于一个云服务供应商来说增加29个点到达99.999%的有效使用时间成本是相当昂贵的,可是并不是所有的用户需要达到99.999%有效使用时间的级别。“杀鸡焉用牛刀?如果一个企业通过云服务仅仅用来运行测试和开发,不在云端进行生产级别的应用程序,那么它完全不需要99.999%的有效运行时间。”

    供应商可以通过向顾客提供服务等级,预算内的价格形成自己在市场上的优势,供应商还可以通过承诺的和标准的有效使用时间形成特色。不是所有的用户都需要HIPPA或是适合FISMA的云服务,但是哪个公司如果想要更好的服务,只需多付些钱就可以。

    云计算基础建设正处于快速商业化的阶段,供应商们必须要提供个性的服务吸引用户,SLAs也许就是可行之道。

Service-level agreements and legal standards for cloud offerings will become more customized to individual customers and vertical industries as the cloud market continues to mature and providers look for ways to differentiate their offerings, researchers at the University of London predict.

Providers today are in many cases looking to push "one-size-fits-all" contracts on customers that favor the provider, the researchers found, but they don't always meet the needs of customers. For example, some vertical industries, such as healthcare, government and finance, each have compliance requirements that need to be addressed before they can more fully embrace a cloud strategy. Providers are only beginning to offer these types of services, and it's a trend researchers expect will pick up steam.

"To remain competitive, providers may have to be more aware of user concerns, more flexible in negotiations, and more willing to demonstrate the security and robustness of their services," says Christopher Millard, lead academic on the Cloud Legal Project at Queen Mary, University of London.

A three-year study by the team found that the six most negotiated terms of cloud contracts were: provider liability, service-level agreements, data protection and security, termination rights, unilateral amendments to service features and intellectual property rights. Those represent some of the top concerns users have regarding the cloud, says Ian Walden, another researcher.

"Companies are generally concerned about the cloud being another mechanism for corporate information to escape their entity," Walden says. "BYOD (bring your own device), combined with cloud-based solutions worry CIOs and security professionals that they are potentially losing control of their data." Providers are only beginning to realize this and create offerings to address such concerns, he says.

There are differences among SLAs from various providers, the researchers found. For example, Amazon Web Services offers 99.95% uptime and availability, whereas many other cloud providers offer up to 99.999% uptime. But within the offerings from the providers, they are not yet customizing them to individual customers on a large scale, the study found.

Kosten Metreweli, CMO at OnApp, which provides a cloud platform for service provider, says SLAs and unique features offer a way for providers to differentiate themselves, and that's good for both providers and users. For example, it can be costly for a provider to add another 9 or two to increase the availability up to 99.999%. But, not all customers need that level of uptime guarantee. "You don't buy a Ferrari and go to the grocery store with it," he says, noting that if a company is just running test and development and not production-grade applicationsin the cloud, then there may not be a need for 99.999% uptime.

Providers that can give customers the level of service, and the prices they desire, will be able to differentiate themselves in the market. Providers can also differentiate on compliance and regulatory uptime. Not all customers will need a HIPPA or FISMA-compliant cloud offering, but the ones who do may be willing to pay a little extra for it.

"In a world where cloud infrastructure is rapidly commoditizing, it's essential for service providers to differentiate on some level," he says. SLA's could be that avenue.
