Is Silverlight More Friendly To Load - Balancing

Mar 1, 2010

I was discussing load-balancing with a colleague at lunch. I admit that I know very little about this topic. We were discussing the various ways of maintaing session in a ASP.NET application -- none of which suited the high performance load balancing that he was looking for. What about Silverlight? says I. As far as I know it is stateless, you've got the app running in the browser and you've got services on the server that feed/process data. Does Silverlight totally negate the need for Session state management? Is it more friendly to load-balancing? Is it something in between?

IIS 6.0 Load Balancing And In - Proc Session

Jan 4, 2010

We have three web servers in our web farm that are load balanced using the Network Load Balancing Manager in Windows 2003. The sites that run on these boxes use In-Proc ASP.NET session. Our assumption is that the balancing uses a "sticky" session because users seem to be assigned to a given server during their use of the application as well as there doesn't appear to be any session error where the session data is residing on a previous machine. My question is how can I 1) verify that our balancing configuration is using "sticky" sessions and 2) can someone explain the load balancing feature in Windows 2003 relative to ASP.NET web applications?

Full Cluster Vs Load Balancing

Sep 16, 2010

Is there any solutions that "increases power of a single machine" instead of traffic distribution between different hosts. I mean the following schema: "Central server" receives all requests and for its execution it provide "a copy of shared memory" to different hosts.

HttpContext.Current.Application During Load Balancing

Oct 13, 2010

I wanted to understand the behavior of HttpContext.Current.Application during the load balancing. I have read that session can be stored in disk hence can be retrieved from different servers. Is this true for HttpContext.Current.Application also. Does the keydata stored in one machine is accessible in other different machine too?

Architecture :: How To Design A Centralized Business Or Service Authentication Architecture

Sep 22, 2010

i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.

And, client "c1" seperately asks seperately how will be the authendication architecture.

so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.

Architecture :: Entity Model Design Framework And N - Tier Architecture

Dec 25, 2010

recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..

1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)

now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!

moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework

Use Session On A Shared Hosting Server With Load Balancing?

Oct 4, 2010

My website/application is in ASP.NET. I use the traditional Session object when people connect so they have their preference, etc. My problem is that sessions were lost very often. I discovered that my hosting company was using load balancing on their servers, so one request on my website can be on one server, and the other on another one.

I tried to store the session data in a SQL Server database, but I quickly discovered that I can't create the needed database on my shared server because I only have one database in my package. Also, there is no guarantee that the rest of the script would have been able to run.

My questions: is there any other way to get around this problem? Should I buy another database only for this? Is there another type of session that I could use? Is there anything else I can use instead of session to keep track of my user when they are connected on my website?

WCF Service Configuration In Web Farm And Load Balancing Environment

Oct 21, 2010

I want to configure ASP.NET Website Project using WCF Service[NetTcp] (both in c#) for web-farm (for website) and NLB Load balancing (for service). I would like to configure following options for same.

NetTcpBinding.maxConcurrentCalls, NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections

Note: During single machine configuration when I changed value of NetTcpBinding.ListenBacklog and NetTcpBinding.MaxConnections in WCF Service project to more that 10, which is default value. I got exception. When I changed this value in Website it was working fine. Due to this I had to keep in default configuration. Not sure why this is the case. Following reference gives idea how to configure in given environment but does not tell how to go about it. Ref: [URL] Update: Let me simplify a bit. Lets say I have following configuration.

2 IIS servers in Web Farm.
3 WCF Service Servers (NetTcp) in NLB
Default config. for single instance.
NetTcpBinding.ListenBacklog: 10
NetTcpBinding.MaxConnections: 10
NetTcpBinding.maxConcurrentCalls: 16

Now what will be my configuration setting in this environment. Will it be same as above or will be as follows.

NetTcpBinding.ListenBacklog: 30 (10*3)
NetTcpBinding.MaxConnections: 30 (10*3)
NetTcpBinding.maxConcurrentCalls: 48 (16*3)

Reporting Services - Load Balancing + Reports (Crystal Or SSRS)

Sep 27, 2010

We currently have two web servers (Windows Server 2008 Standard, IIS7) setup to host an ASP.Net website and are using the basic features of our hardware firewall to provide network load balancing (NLB) between the two servers. This means we have had to change the ASP.Net session state mode to SQL Server in order to make the data stored in session accessible no matter which server responds to the request. The main issue now is that crystal reports (basic edition packaged with VS2008) do not seem to support serialization which is needed in order to store/transfer the report to session state on SQL Server.

From what I have read so far in order to get crystal reports working in a web farm environment it seems the only option is to upgrade to Crystal Reports Server and load the reports from a third server. Another option may be to use SQL Server Reporting Services (SSRS) as we already have this so no extra cost involved, however I'm not sure if SSRS would resolve the issue with storing reports in session?
