4. Web Application Installation
approaches
• Local Server
– Installing Web Server, DBMS, and application server
in one’s PC
– Advantage:
Great for development and testing , full control over
server configurations
– Disadvantage:
Transferring files from local to the server, changing
configuration

5. Web Application Installation
approaches
• Remote Server
– Hosting company that has web technologies set up
and running 24/7
– Advantage
avoided installing software on your pc, eliminate
transferring from local to remote
– Disadvantage
Risk the accessibility and health of the website,
