multi-tenant

I am developing a web application for data analysis on agricultural datasets. Actually I want to make the application to be multi tenant and I wish to deploy that SaaS application in a private cloud (in our school). I got a few basic doubt in the programming part. Do I need to develop the application in the Hadoop's map/reduce functionality? Secondly,the selection of database. Since the data are highly structural in nature (like sql) can I use a sql server to manage data in cloud? In such do I need any middleware in addition to the IaaS setup and the SaaS application? I am using J2EE

I've a full application coded. Now, the only part missing is to make it multi-tenancy. I want to allow clients to register into my application website and get an instance of the application with a completely empty database only for that account. I've thought to play with environments, but I'm not sure if this is a good approach: config - user1 - database.php - user2 - database.php - ... I've also thought about a unique config file containing the database information about every account and set the database connection based on the subdomain name. Something like I've seen in this post: Multi

I building multitenancy into the unit of work for a set of services. I want to keep the tenancy question out of the way of day-to-day business domain work, and I do not want to touch every existing consumer in the system (I am retrofitting the multitenancy onto a system without any prior concept of a tenant). Most messages in the system will be contexted by a tenant. However, there will be some infrastructure messages which will not be, particularly for the purpose of automating tenant creation. I need a way of determining whether to use a tenant-contexted unit of work, or a infrastructure

How to implement a mechanism (within a single ASP.NET MVC application) to ensure that: if request comes on mydomain (user visits mydomain.com) -> handle using certain set of controllers if request comes on otherdomain (user visits otherdomain.com) -> handle using different set of controllers (the domains are aliased to the same web hosting) What extension points within ASP.NET MVC should I use to ensure that the described mechanism works? Adrian Grigore I think you could implement a IRouteConstraint descendant that analyzes the current HttpContext and matches (or does not match) a route

I'm looking for the easiest & performant way to make a multitenant express.js app for managing projects. Reading several blogs and articles, I figured out that, for my application, would be nice to have a database per tenant architecture. My first try has been to use subdomains to detect the tenant, and then map the subdomain to a mongodb database. I came up with this express middlewares var mongoose = require('mongoose'); var debug = require('debug')('app:middleware:mongooseInstance'); var conns []; function mongooseInstance (req, res, next) { var sub = req.sub = req.subdomains[0] || 'app'; /

I am architecting a software project and I want to achieve a SAAS (Software As a service) model. I want to design a web application compatible to multi tenancy with separate database per tenant.

Thanks in advance. techuser soma This post has details on the database architecture for multitenancy. How can i
