I've been all around the net for weeks now trying to figure out the best way to set up a Multi-tenant website (building a web app that multiple companies and their employees will use). As far as a database goes, I am interested in using one database with a copied set of tables for each company. As far as managing the login and security in MVC2 I am lost with the myriad of examples (mostly old and not MVC) that I have seen. So ideally my app would allow a company rep to register their company and then be able to add their own employees to the site. Then all employees could login and be securely associated with their own company's tables (table names would be appended with their AccountID).
I'm not sure if this would be handled using routing or session variables or what the more ideal and up to date methods might be. Like others who have discussed this issue, it seems like this should be a much more fleshed out solution as it is becoming a more common use on the internet. I'm even willing to simplify the database down to one set of tables that stores an AccountID in each row if needed.
im trying to build my first multi-tenant application, i used a shared database and it is complete now, i want to build the app now, and i tried this approach: all urls in the app have the following form ~/user/page.aspx(user directory is logical) where user is the current user, which is saved in a session after he logs in. when the user requests a page, say ~/user/profile.aspx, he is routed to the real page ~/profile.aspx and then his data are retrieved from the database. i dont think this is how multi tenant applications work, but i couldnt think of another method.
My application is used by several customers, who needs to maintain their own database. Currently I'm keeping all the connectionstrings and according to the user, change it. (In a case of CRUD operation). Is this errenous way? I don't know much about MultiTenant applications. Is that the best solution for my problem?
I'm building a multi-tenant ASP .NET application. Given that each tenant can configure their application dynamically (which may involve dynamic custom assemblies being loaded into memory), I need a means of isolating each tenant.
I'd prefer not to create a new Web Application per tenant for maintenance reasons.
I've was considering using the AppDomainManager to create an AppDomain per application, but it seems this is not intended to be used for ASP .NET applications.
I have been seeking the best way, or at least a good way, to handle Client Access for a Multi-Tenant/SaaS-type web app designed with MVC 2.There are no tricks as far as client customizations needed here. So every company will have the same experience on the app. I just need to understand how I can isolate the experience so that a logged in user only sees data relevant to his company. My tactic is that my database houses a "tenantID" column for each row so I can easily isolate the rows that way. I am wondering if the default provider using the ASPNETDB.mdf can be modified to route users to their assigned company data. I have seen examples using route paths ({tenant}/{controller}/{action}/{id}) but even those threads express doubts. So if anyone has a good method that they are comfortable with, I am all ears (or eyes).
In a multitenant system that hosts multiple organizations and applications, where an organization may use several applications hosted on the system, should my user and role model be such that a single user or role can exist across multiple applications and organizations? Or should I limit a user entity to a single organization/application pair and then define some overarching model to tie those user entities together? That is: John Doe is a person He wants to use ApplicationA and ApplicationB He works for two different companies (just bear with me), OrganizationA and OrganizationB Should the user model be:
johndoe@someuniquesuffix is his unique user name. This gives him access to both applications for both organizations. johndoe@applicationa@organizationa is his username for ApplicationA at OrganizationA. [URL]is his username for ApplicationB at organizationA...and the same for OrganizationB. Then have some "master" list that says that all 4 user accounts for the apps/orgs correspond to the same actual "person", John Doe?
The same scenario(s) described above applies to how I will design my Role schema.
I can do the database and security side with no problems, I can also get the hostname from the URL, but what I am struggling to find out is how to create the basic plumbing that would allow a new customer to sign up online, provide their company name, and for the application to create the new URL, ready to be used straight away.
I currently have a MVC2 application hosted on premise that allows the user to add custom extensions (controllers, filters, views, validators) so that they can extend the application to suit their needs. I'm using MEF as my composition container, but MVC2 relies on the extensions (assemblies, views and scripts) to be located in a particular directory or found at runtime based on a configuration setting. The MEF catalog is instantiated at startup meaning if any new extensions are required to be added or updated then the application needs to be restarted. This is all fine in a single-tenant world but now I want to make it multi-tenant hosted in the azure cloud.
The problem I forsee is the location of the custom extensions and how they are deployed. My initial thought is to use azure blob storage (one per tenant) to store the custom extensions and then download per-session (rather than Application Startup), however in the past the way MVC has worked is it tries to resolve assemblies and find views within the current AppDomain whereas my assemblies and their embedded resources will be in memory.
I'm after a bit of advice on how to handle a multi tenant site in ASP.NET from a UI perspective. What I want to be able to offer is a choice of layouts to the client i.e.
Layout 1: Navigation horizontal at the top. Search results in a table in the middle. Some text at the bottom.
Layout 2: Navigation vertical on the left. Some text in the middle. Search results at the bottom
Layout 3, Layout 4, Layout x etc...
Each element within the various layouts can differ too. For example, the search results might look like simple list in Layout 1, but will have a completely different look in Layout 2. Once a client has decided on Layout x, I then need to apply their company identity to the layout by changing the colours, logos, etc.
I have scoured the web and have yet to find and example that matches my requirements.
What I have is an existing multi-tenant asp.net application where all users authenticate against a single SQL Server database. This database also contains several other settings type data that is used within the application. Each client after authentication, utilizes thier own SQL Server database for data storage, for isolation purposes. Essentially all of the client database are identical and reside on the same server, but reside on one or more servers as well.
The application is currently written in asp.net 2.5 framework and utilizes the Micrsoft Practices Enterprise Library for DAL. Wnd we are looking to migrate to 4.0 and implement NHibernate to replace the MPEL.
I have implemented a solution already using NHibernate and the 4.0 framework, so I am familar with the concepts. I found the resources for my current session manager here as a matter of fact. But that application only had a single database, so not much too it.
The implementation is essentially what you see here:
[URL]
The other solutions that I have seen multiple config entries and/or files to manage this, but that is not desireable, since we may add new clients frequently and all of the connection information is already maintained in the authentication database.
I am developing a web application which implements membership, roles and profiles. I also want it to be multi-tenant / multi-domain. By this I mean that I will have hundreds of domain names pointing at the same web application. I want users to be able to create accounts at each individual domain. I want the opposite of "single sign on". I want users to be able to use the same username, email address and password (or different ones, at their choice) to create accounts at the different sites. I do not want users to have any awareness that the different domains have any relation to each other as they will look different and have different content. The first problem I run into is that usernames have to be unique within the forms auth aspnet db.
Well, if they want to use the same username to register on 10 different sites then I need to support that. My first thought was that instead of identifying a user by their username, I need to extend the aspnet tables and sprocs to consider the username + a unique site identifier. Is there any sample code or has anyone else ever done this before? Should I just abandon the built in aspnet forms auth and roll my own custom auth scheme? The data on the sites is not sensitive so security isn't really that important to me.
we are building a multi-tenant application, which will support that each tenant can have a unique top level domain, the application is build using the asp.net 3.5 and SQL servr 2005, while each tenant will have different database. I have seen a number of questions about the similar applications on the StackOverFlow, but none of them is related to the Testing, I want to know is how one can test the application in a development environment, specially How can we test that each customer connects to his own DB based on the URL. how can we emulate different domains on the local system. like [URL] and [URL]all goes to dev machine's IIS.
The content of the web site I am creating is expected to store data for multiple languages. What I mean by the content is the actual data stored in the database (SQL Server 2008 R2). For example I have a database table to store available packages and one of the columns in this table is the description which is shown on the web site. This description should be stored in multiple languages for example (en, fr, de). What is the best way(s) to get this done, I can of course have the same table with multiple columns (each column representing a single language) and code the data access layer to load the proper column based on the current language, but is there an easier way? An ideal situation is where like in ASP.NET the database automatically detects the current language and return the proper column
Even though I'm trying to implement exception handling in a multi-tiered Windows application, catching and throwing exceptions should be the same for Windows and Web (sans global.asax and web.config custom errors).
I have a webform with a texbox that displays exceptions. So my webform invokes a method in BusinessTier class which then invokes a method in DataTier class. How can I throw my DataTier method exception so it reaches my webform?
assume I have a multi layer application with the following logical separation between layer:
Presentation Layer Service Layer business Layer Data access layer
I'd like to use a custom asp.net membership provider for authentication/authorization in my app. which is the best layer where to put the custom asp.net membership provider?
I've created a photo database and search engine that creates a xml that corresponds to the multiscale image xml.My problem is how to enable multi users to search at the same time?
Our current application is working fine but when you try to misbehave like we found out that When login with same user in multiple tab with different organization(there is a organization dropdown in the master page which sets the cookie whenever it is changed.) in tab one it is org 1 and tab 2 it is org2 , cookie has the later org 2 in it but when we go back in tab1(which had org1) and save the record org 2 will be saved with the record So can some one share some sort of a checklist with us which address these types of problem.
I'm trying to do some multi-threading in my asp.net web site. But I'm having trouble getting my child thread to interact with my main thread. In the following very simple example I would expect that, 3 seconds after clicking the button, the "Hello World" text would be displayed on my page and on my label. Instead, after a few seconds, I get the following error in a pop-up box "WebDev.WebServer20.exe has stopped working - Windows is checking for a solution to the problem.". I am running Visual Web Developer 2010 Express. If you know why I'm getting this error and if you know how to fix the problem respond.
I want to put my website project and admin website under same project as I want to use session and authentication of the main site. Also I want to show the admin, the page, where he has made changes. But the problem is whenever I will change anything in admin pages, I've to build the entire website. I don't want to do that. Can I build that separately?
I don't want to choose the option of building all pages separately as well.
Is there any alternatives of doing that. Separate projects for admin and website will come up with many other challenges. So I would like to avoid that.
I am building a website using Asp.net with C# and back end support is SQL server.How to add multilingual support to it?Like in google or facebook there are various link button for various languages?I want to implement the same thing.
I created a website with a single project solution. Each web page consists of C# code in a script block along with the markup. In order to make the website work with many languages, now realize that I will need to have the code for each page reside in separate code-behind files that can be combined with the markup in various languages. I assume this means that I will need a solution with a common project of code-behind files that is merged with a project of markup files for each language in order to create websites for host servers in the various countries. After I separate the code into code-behind files from the markup for each web page, I will need to know how to organize the solution for debugging and building each website and where to place each file.
How i develop multi language website in asp.net for this what steps i need if i already have sqlserver db,design template, requirements stuff and application flow
I want to build multi-language website in asp.net 2008 and asp.net 2010. So, which process is better for building application? Using either Local and Global Resource or New Folder to make separate according to language?
Application performance should be good and also easy manageable.
