你的业务应该在云上吗?

也许是时候采取行动了

小企业继续听到这种声音 “把它带到云端” over and over yet rarely do people stop to explain the concept, advantages, disadvantages and risks. I hope this article helps small business owners determine if “云” is something that provides a strategic advantage or adds more risk.

2010年10月,微软的云广告掀起了这股热潮. 三个广告中有一个是关于创业公司的. The commercials have been fun and intriguing which is a trademark of Microsoft.

With three primetime commercial spots, I give full credit to Microsoft for making “云” 一个家喻户晓的词. Its true goal was to reach presidents and CEOs around the world to rebrand and re-stimulate an old concept, 应用软件提供商(ASP).

首先,让我从较高的层次来解释云服务的含义. The expansion of the Internet during the 1990s brought about a new offering of hosted application computing called Application Service Providers. asp托管和管理专门的业务应用程序, with the goal of reducing cost by central administration and through the solution provider's specialization in a particular business application. The servers and storage that hosted these applications were in large datacenters around the country. The cloud hasn’t changed what ASP offered, but has simply re-branded the terminology around it.

像微软这样的云提供商, Rackspace and Amazon all provide access to your applications via the Internet. Your applications can be accessed from web browsers, desktops and mobile devices. The 云 provider typically takes care of worrying about which servers and storage your application reside on. You are relieved from having to worry about hardware and refreshing it every five years.

云计算有很多选择:

  • 转换现有服务器 转换为虚拟格式,并将其移动到云中. 后来, 你不需要担心硬件, 你可以通过互联网安全地访问你的服务器. 这些被称为专用虚拟机. Sometimes your desktops are virtualized and hosted along with your servers to increase performance.
  • 将公司数据从服务器上移走 到您的云提供商的新共享虚拟服务器上. 这可以应用于数据共享(文件)、电子邮件等. Typically the application has to allow for slower connection speeds.
  • 利用交钥匙托管应用程序 where your data resides in a hosting company's own applications. 例子包括Salesforce.com、SAP等. 你可能还听说过“软件即服务”(SAAS).

迁移到云对企业来说可能是一个复杂的决策. Many believe the cost will be lower, but that is not always the case. We recommend that you have a third party neutral assessment to see if it’s a good fit for your company.

Your business applications should be inventoried and assessed to see if they can be moved to a cloud environment without affecting performance to those applications. 云 computing is not always about costs savings for companies but can be a great way to gain redundancy, resilience and remove the need to worry about replacing hardware every five years. The datacenters that house cloud applications offer 24/7 resilience and redundancy in all components. Most companies cannot afford to have redundant dedicated A/C, power, Internet, servers, storage, etc.

关键在于您的业务应用程序. If your company uses industry specific applications that require dedicated internal servers and databases, 迁移到云的决定可能要困难得多. If applications include email, file sharing and other more standard or web based applications, then “云”可能是完美的搭配.

云的优势:

  1. Removes high initial cost of hardware and software associated with servers, storage and applications
  2. Removes inconveniences associated with upgrading hardware and software every five years
  3. 可以消除对工作站和个人电脑在办公室的需要
  4. 允许远程工作人员从任何地方访问应用程序
  5. 允许为新的需求快速提供服务器

云的缺点:

  1. 取决于业务软件应用程序, the five year recurring costs are typically higher than purchasing hardware and software every five years
  2. 办公室的互联网连接变得至关重要. The office Internet connection has to be up to allow your employees to reach your business applications
  3. Specialized business applications may not perform as well as having them internal
  4. Data control can be a concern with some cloud providers when your data is stored inside their hosted applications
  5. 安全 of your data and applications has to be closely inspected to ensure it is not vulnerable
