I am writing a simple diary application. I am using a monthcalendar control to select the date to load the diary. I need the control to display the date in bolded if that date on the calendar has the data. That is easy and simple. Just using BoldedDates.
Cloud computing is moving some of your local computer tasks into internet via webservices, such as office application and data storage. One of the classic examples, GoogleApp, there is a set of office applications which are similar with your MS Office. But they are running on their servers instead of running in your local computer.
Those servers are a huge processing tasks. None of single server can handle those kind of jobs. So, normally, cloud computing will run on a cloud platform. The clould platform is using grid computing, therefore, grouping a set of computers to form a cluster. Not many companies are providing this kind of service at this moment.
