IIS, Web Server, Web Garden, Application Pool, Worker Process<\/h2>\n

1. IIS (Internet Information Services):<\/h3>\n

IIS is a web server created by Microsoft to serve web content, including websites, web applications, and APIs. It is a platform that supports HTTP, HTTPS, FTP, SMTP, and other protocols.<\/p>\n

2. Web Server:<\/h3>\n

A web server is a system responsible for handling incoming web requests (HTTP\/HTTPS) from clients (browsers) and responding with the appropriate content.<\/p>\n

3. Web Garden:<\/h3>\n

A Web Garden is a configuration in IIS where multiple worker processes are assigned to a single application pool. This increases scalability and reliability within the same server.<\/p>\n

4. Application Pool:<\/h3>\n

An Application Pool is a logical container in IIS that isolates one or more web applications. Each application pool runs independently and provides better resource management.<\/p>\n

5. Worker Process (w3wp.exe):<\/h3>\n

The worker process (w3wp.exe) handles the incoming web requests, executes the required server-side code, and sends the response back to the client. It is the core component that processes web requests in IIS.<\/p>\n

Tricky Interview Questions<\/h2>\n

1. What is the difference between a Web Garden and a Web Farm?<\/h3>\n

A Web Garden allows multiple worker processes within a single server, while a Web Farm distributes the workload across multiple servers for load balancing and redundancy.<\/p>\n

2. How does IIS handle multiple web applications running under the same server?<\/h3>\n

IIS uses Application Pools to isolate different web applications, providing each with its own worker process.<\/p>\n

3. Why would you use a Web Garden instead of a Web Farm?<\/h3>\n

A Web Garden is used to increase concurrency within a single server by running multiple worker processes, while a Web Farm is used for horizontal scaling by distributing the load across multiple servers.<\/p>\n

4. Can an Application Pool have more than one Worker Process?<\/h3>\n

Yes, an Application Pool can have multiple worker processes when configured as a Web Garden.<\/p>\n<\/div>\n
