13. Optimization of web performance
Page content
Optimize html and images
Reduce comments and white spaces
Page generation
Server response time. Multiple servers.
Device based accelerators
Page delivery
Edge caching (Akamai)
Bandwidth
Edge caching refers to the use of caching servers to store content closer to end users.
most international newspapers send out one master “copy” to printing presses around the world, who then duplicate those newspapers and deliver them locally
In this example, End User A requests a page from End User A is connected to the closest Akamai caching server, Akamai Edge caching server A. The Akamai Edge caching server A doesn't have a copy of the requested page so it goes back to origin. the server that actually resides at Penn, gets a copy of the requested page, and serves the copy of the page back to End User A.

14. Architecture Simple vs. multi-tiered architecture Simple Tiered
Static web page serving
Tiered
Product sales
Dynamic web serving
Data serving

15. Two-Tier Request for page  web server  Dynamic content database
A web server responds to requests for web pages and a database server provides backend data storage.

16. Multi-tier architecture
Requests web server(s)  Middle Tier (application servers, database servers, ad servers, mail servers, etc.)  Backend server (corporate applications, finance, production, enterprise systems, HR systems, etc.)
A web server is linked to a middle-tier layer as well as to backend corporate systems.

17. Web server software Apache 63% - Unix choice Microsoft 27%
Others – 10% (Zeus, SunONE, etc).

18. Site Management tools
Identify invalid links, dead links and orphan files

19. Dynamic page generation tools
Contents of web pages are stored as objects and converted to html upon request.
The objects are retrieved from databases using CGI (common gateway interface), ASP (Active Server pages), JSP (Java Server pages) or other server-side programs.
ODBC (Open Database Connectivity) is the standard access method.

20. Application Servers Middleware software List server Proxy server
Mail server
Catalog display
Shopping cart
Fax server
Auction server
