A guide to developing cloud services for family/community/corporations. The book discusses the management of events, contacts, and projects, as well as collaboration on Word Processing, Spreadsheets, databases, and presentations.
The control of these services through a Web-based Desktop is described. Applications and documents are moving from desktop to the cloud, which is thousands of computers/servers linked by the Internet, giving access to all programs and documents from any computer on the Internet.
Already on the cloud are Gmail and Hotmail, as well as Google Calendar, Flickr, and Picasa Web Albums.
The book list 15 advantages to cloud computing, such as lower cost computers, performance improvement, lower IT infrastructure costs, and fewer maintenance issues.
Six disadvantages are listed, such as the need for a constant, high-speed Internet connection, and the relative insecurity of the data. If the cloud loses your data, you better have your own backup. Confidential documents may not be secure enough on the cloud.
Cloud Service Development is mainly in the SaaS (Software as a Service) arena.
Offering cloud services are Amazon, Google App Engine, IBM, and Salesforce.com. There are a slew of web-based database and presentation services in the cloud. I discovered that Adobe Photoshop Express has a free online photo editor, with storage of 2GB, and a connection to Flickr for greater storage.
Not a general discussion of cloud computing, but a very useful guide to the use of the cloud in personal and business applications.
