There are many technologies which can make standard standalone applications available on cloud. Now, FORUM8 is developing generic frame work system, "a3S" which enables cloud computing of general application at lower cost.

It is designed to be applied to many applications. It is composed of two major features, data communication technology between server and client, and management of server firmware. We named it "Anything as a Sever" (AssS) and call it "a3S".

We have two options to make application available on cloud.

1. In this option, we need to develop application dedicated application for client. All commands of application have to be encapsulated in network protocol. And we need more programming development in message processing between server and client and in user interface of client.

2. In this second option, application codes have to be translated to programming language which works in server. The example of these language are PHP, Python and Javascript., They are suitable to script than application programming. It takes long time to convert application code. In addition, application has to be modified to web language.

"a3S cloud system" is designed to clear defects in these options above and easy to use for both end user and developer. "a3S could system" adopts option 1 above, and it provides generic framework with which user does not need basic development of data communication.

In a3S, original application is loaded in server, and data, video and audio of application are sent to a3S in server. a3S in client receives them and application works at client and input data or command is sent to a3S in client and then a3S in server. To utilizes these features, we provide API for server module and for client module.

a3S in serve compresses data when needed, and latest data is sent to client continuously. In client, user operation is monitored and necessary data or command is sent it to server application.

With this technology, many various ion applications can work on cloud. I

We will describe systematic mechanism of a3S in next issue.
