    copied!<p>I'm trying to bootstrap a micro ISV on my nights and weekends. I have an application at a very early stage of development. It is written in C# and consists mainly of a collection of classes representing the problem domain. At this point there's no UI or data persistence. (I haven't even settled on the .NET platform. Its early enough that I could change to Java or native executables)</p> <p>My goal for this application is that it will be a hybrid single user/ occasionally connected multiuser application. The single user part will use an embedded database for local storage. This is a development model I'm familiar with. </p> <p>The multiuser part is where I have no prior experience. I know each user will need two things:</p> <ul> <li><p>IP based communication to a remote server on the public internet</p></li> <li><p>User authentication and remote data storage</p></li> </ul> <p>I have an idea of what services I want this server to provide (information lookup and user to user transactions) but beyond that I'm out of my element. The server will need to be hosted by a third party since I don't have resources to run my own server. Keeping in mind that I will be the sole developer for this project for the foreseeable future:</p> <ol> <li><p>Which technologies would be the simplest way to implement the two things mentioned above? Direct access to the datastore/database or is it better to isolate it? Should I implement a webservice? If so, SOAP or REST? </p></li> <li><p>What other things do I need to consider when moving to a multiuser application? I know security is a greater concern in a multiuser application. Especially when your dealing with any kind of banking information(which I will). Performance can be an issue when dealing with a remote connection and large numbers of users. Anything else I'm overlooking?</p></li> </ol>
