There is a really great thing about cloud computing. It’s in the cloud. However, when I talk to a number of organizations they still want to treat cloud-based services as if they operate just like an on-premise solution. However, a solution that is deployed on-premise has some major differences from a solution that lives in the cloud. Namely, a solution that is on-premise is all yours to muck with. Therefore, the things (customizations) that you do with an on-premise solution are not always transferable to a cloud-based solution.
Sadly this is where I tend to differ in opinion with someone that is looking towards the wonderful world of cloud computing to solve their on-premise woes. For you see, our clients will tend to ask for some form of gap analysis between everything they do on-premise and what the cloud offers. Easy enough, right? Well no. I’m not talking about a straight laced feature by feature gap analysis. Instead, most people are asking for us to analyze every single business process that they have in relation to a particular technology and then map it into a cloud based solution. In other words, instead of asking if BPOS supports IMAP, the question becomes I’m doing this one particular business process using IMAP in some unsupported fashion using some custom code. Can we migrate this to BPOS?
好了，任何人都认为云是这个真正伟大的沙箱没有墙壁，当你觉得合适，你可以建立沙堡，请停止思考这一点。除非你付出的钱吨一些专用的解决方案，你必须同时也是继同一套规则与其他人相同的沙箱游戏。换句话说，基于云的解决方案绝不是一个一对一匹配的一切，你正在做内部部署。相反，基于云的解决方案往往是一个高度标准化的解决方案，让每个人都有相同的功能集为一个真正伟大的价格。
Therefore, when you a looking a cloud-based solution you should assume that the solution will not provide an end-all to your IT woes. Rather, you should think of these solutions as a complement to your on-site operations that will solve a particular set of problems (cost, manageability, resource usage, etc.). With this in mind, that is why most cloud-based vendors provide some form of “free” trial. I know Microsoft does, Google does, Salesforce does, and so on. Using this trial, I highly recommend that you “try” things out. Play with the solution, figure out what it does and does not do, and start developing insight into what business processes map into it. Heck, given that these solutions live in the cloud, you can even play with them without impacting your production systems.
所以，当面对决定去云，我强烈建议你制定云计算解决方案，峰的兴趣的理解。使用试验，然后找出提供解决方案最能满足到你的环境中的功能如何。走向另一个方向似乎只是游泳上游。
