The application provides simple load balancing to distribute user sessions and the load generated by them around several processes or even servers. To do this, the application is installed multiple times on the same or on other servers.
All collaborating applications that can be logged into, are declared in the applications' Application pool. The selected load balancing algorithm distributes user logins to the defined applications.
|
NOTE: Even if only one application is installed, it must be defined in your application pool, otherwise you cannot log in. |
Algorithm | Description |
---|---|
DistributeEqually |
This algorithm distributes user logins such that each application in one language has the same number of active users, if possible. This algorithm is the default and is required in 99% of cases. |
DistributeSuccessively |
This algorithm distributes user logins by order of application definition in the application pool. First of all, all user logins are forwarded to the first application in the desired language. When this has reached it maximum load, logins are forwarded to the next application. |
Load balancing solves the following problems:
Language is fixed for per application so that an application can only provide user sessions in one language. If users can log in with multiple languages, at least one application must be installed for each language.
If several applications are installed and assigned to different Internet Information Services application pools, they are started in separate processes. Under Windows 32-bit operating system each process can address 4 GB memory, for example, but can only use 2 GB. ASP.Net reserves another 40% so that only 1,2 GB of memory are available to the application. Through multiple installations, these 1,2 GB of memory can be put to multiple use, thus taking advantage of the available physically main memory.
Performance can be noticeably improved by installing on several servers.
Multiple installation does not necessary complete outage if just one of the installed application fails.
The application supports a single sign-on that allows users to authenticate themselves without them having to authenticate user name and password again.
Prerequisites required:
You can disable anonymous access on the web server. This means the user's browser must provide the data required for authentication.
