Architecture
Web applications
Client-Server communication
Storage Tier
Storage Tier Where information is stored and retrieved.
What to choose?
Relational database• Utilize relationship between tables
• Flexible
• Easy to update/delete records
• Avoids duplicate data
NoSQL database• Schema-less approach
• Easy to Scale
• Fast !
What database to choose?
Depends on your Software requirements
Server Tier
Server side scripting
Key rules• Security
• Performance
• Scalability
Server Tier: Security• Cross Site Scripting (XSS):
o enables attackers to inject client-side script into Web pages viewed by other users
• SQL injection:o done by passing SQL statements in an entry field in an attempt
to get the website to pass rogue SQL command to the database
• denial-of-service attack (DoS attack):o an attempt to make a machine or network resource
unavailable to its intended users
• Remote code execution:o ability to execute any commands of the attacker's choice on a
target machine or in a target process
Server Tier: Performance
• Minimize response time• Code matters !!
o Find the simplest solution to a problemo Avoid too many database callso Merge loopso Review your algorithms
Server Tier: Performance
• Cache pages
• Cache database queries
• Use “Cache-Control” headers
• Cache function returns
Server Tier: Performance
• Merge JavaScript in a single file
• Merge CSS in a single file
• Compress CSS and JS in production
Server Tier: Scalability
• The ability of a system to handle a growing amount of work in a capable manner or its ability to be enlarged to accommodate that growth
Scalability methods
Client Tier
Client Tier• Client Side Programming
• User Experience
• Browsers Compatibility
Client Side Programming
Flash
User Experience1. Make pages load faster2. Don’t make the user think
Use clear navigation, clear language, clear layout

to know your users and the most common browsers between them
• Minimize using CSS3 and HTML5 if possible or use an alternative depends on the browser
• Use JS frameworks/libraries like Jquery or MooTools
Common Web development tips
• For rapid development use MVC frameworks:o CodeIgniter, CakePHP, Django, ASP.NET
• Use Cloud solutions for server architecture:o Amazon AWS, IBM Cloud, Azure
• “Simplicity is the soul of efficiency”o -Austin Freeman
• “Make it Work Before You Make it Fast”o -Brian Smits
