Architecture :: Scalable ASP.NET Architecture
Mar 2, 2011
Hi,
We host a web portal for the recruitment of staffs. The portal had close to sixty thousand (60,000 applicants/day) successfully registered applicants a day and at its peak period during the day the portal was hit with close to ten thousand (10,000 applicants/hour)
registrations an hour.
The Application process includes a number of functions such as
- Mail confirmation
- Upload of images
- Generation of unique Identification Numbers
- Providing information for the completion of the Application Form of various categories
- Print out of the Application Form
The form also maintains a login profile for each successful applicant and this is seen at the top of the application form when the user is logged in.
ARCHITECTURE
- The system was built using ASP.NET and MSSQL was used as a database for the data collected on the same physical server
- ASP.NET membership was the Application Programming Interface (API) used for user authentication and role management due to its flexibility and the ease of use.
- The passwords are hashed in the database.
- LINQ was used as the adapter for data handling to the database server
- Uploaded images was stored in a folder in the file system
HOSTING PLATFORM
- 32-bit processor
- Rackspace cloud computing
- 8Gig RAM
- Windows server 2008
ISSUES ENCOUNTERED
- At peak period, the portal was overloaded and had a very slow response time
- SQL server reporting services ran out of memory when we generated reports due to size of the report.
We want an overhaul of the architecture that would enable more applications to be filled simultaneously without issues i.e. a site that can sustain the load, But I am not sure what to do.
any advice would be great in regards to architecture?

I am looking details on the internal working of asp.net architecture. The topics need to include the following:
Asp.Net Thread/Application Pools HttpRuntime HttpApplication - When and how it is set up How HttpContext is set up How objects can passed along the pipeline using HttpContext.Current.Items Why does modification of static variables requires locks in ASP.NET (advanced)IIS 7 Integration Mode

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.

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

I am working on 3 tier architecture: UI, BL, DAL. In my UI i have following code for Asynchronous page processing:
[Code]....
But I want a database fetch operation to be performed in this asyncronous method. And due to 3 tier arch. i am unable to do this in UI Layer. Can anyone guide me that how can I implement Asynchronous processing in 3 tier architecture? Note: If you are going to place EndAsyncWork1 in DAL then show that how can I return a value back to UI layer from this function.
[Code]....

I want to know that What are the factors if we use methods on each .cs page for connection and executing query on each aspx code behind page rather then using BAL .
How our application get affected in terms of performance and speed or other way?
when we put our website on server after publish/compile in general approach (using query in C# code behind) rathor than using stored procedures?
then which logic is better and why ?

I have implemented the 3-tier architecture project; DAL, BAL, and presentation layer are three layers in it. I am going to implement the following scenario:
Presentation layer calls to a function in the BAL layer which returns 2 string variable, and in turn this function from BAL layer calls to a DAL layer function which also returns 2 string variable. How can I implement the above scenario?

I was told by my manager that in a few weeks or so we would be getting a bigger project and I need to be well versed with Design Patterns and N tier arcihtecture.
I would really appreciate if someone could provide me some links and also drop me a few sentences on how this things are useful?

I am try to create architecture design for WCF service.
We have WCF service that we have to expose to third party so then can request with xml and get back xml response.
The wcf service should do the following:
- Accept the request call with xml
- Check xml against the schema
- Parse the xml
- Authenticate the incoming xml by username and password that will be in xml
- Send back the response
If anybody can let me know what kind of design I can use or is there any pattern available that I can take it and then extend it as per my requirement.

I am trying to use a 3-tier architecture (UI, BAL & DAL) for my project. I have each of the tier in different physical machines.
UI - Machine 1
BAL - Machine 2
DAL - Machine 3
How can DAL & BAL interact? What would be the best way to call one component from another?

I was tasked to create 3 tier web application. However, i browsed through many books & tutorials. The examples are doing it using Object data source which my lecturers claimed that it is not 3 tier at all. Shouldn't be dragging any data source into deisgn view. Any comprehensive examples for me to take reference from?

i want to develop an application in asp.net using 3 tier architecture .
i know that there are three layers
Data layerBusiness Layer
Data Access LayerBusiness Logic Layer Presentation Layer. I am confused between Data Access Layer and Business Logic Layer.
In data access layer we develop the property classes and main class function which returns datasets, datatables and data reader to Presentation layer.
what is the use of Business Logic Layer ? what actually we do in Business logic Layer
?? we can pass data directly from data access layer to presentation layer ?

i am in the process of creating 3 tier architecture for ASP.net with Microsoft Studio 2005.
My architerture is as below
Presentation Layer Business Logic Layer Data Access Layer
-------------------------- --------------------------- -------------------------------
Form1 BLTable1 DaTable1
(NameSpace = MyCompany.MyProject.BL. BLTable1) (NameSpace = MyCompany.MyProject.DA. DaTable1)
Form2 BLTable2 DaTable2
(NameSpace = MyCompany.MyProject.BL. BLTable2) (NameSpace =
MyCompany.MyProject.DA. DaTable2)
Form3 BLTable3 DaTable3
(NameSpace = MyCompany.MyProject.BL. BLTable3) (NameSpace = MyCompany.MyProject.DA. DaTable3)
I have 2 question here:
(1).MSDN say that we should not have the namespace where its name is same with class name but it does not exlpain why.Does anyone know why? The msdn page is
http://msdn.microsoft.com/en-us/library/893ke618%28VS.71%29.aspx
(2). Business Logic Layer BLTable1 need to interact with Data Access Layer
DaTable1 , so i put the code: imports MyCompany.MyProject.DA. DaTable1 inside
BLTable1, so that i can have access to all the public shared method inside
DaTable1 in BLTable1 for example : DaTable1.Save()
But problem arise when BLTable1 want to use the public shared method in BLTable2 .
I have put the code imports MyCompany.MyProject.BL. BLTable2 inside BLTable1,but i need to
key in the class name twice only can access to the public shared method inside
BLTable2 for example :BLTable2.BLTable2.Save.

I'm supposed to be designing solution architecture for an upcoming project (clearly the most advance I ever did and guaranteed to drive me nuts over the coming months). I'm trying not to let my knowledge shape the design, and rather create a solid, maintainable design and fill the gaps in my knowledge later.Was hoping to hear what others think and help me shape this.In a nutshell it will be an asp.net mvc application running on the azure platform (so I'll be using azure table services for data storage and blob services for file services).
Been nutting out Entity Framework 4 (don't know NHibernate at all) over the past few days and figured I'll use that in the data access layer (c# class library) to map my domain model (another c# class library) to the data storage (still no idea how azure storage work, but will get to that).My WCF skills are shaky, but I'm thinking of exposing data via services, though right now I cannot think of that being that useful....
Front End: XHTML, CSS, JavaScript (jQuery & jQueryTools), AJAXWeb Client: Asp.Net MVC 2Domain Model: C# Class library with POCO , interfaces and implementations (will be using Castle Windsor as IoC)Data Access Layer: Entity Framework mapping my domain model and data storageAzure Storage: ...

So,I'm looking for online training that maybe help me to learn about the architecure and design pattern and how to use them in my website project?
