WEB TECHNOLOGIES

Valbuena, Francis Eric



Web Language: Ruby

Web Server : Apache

Server OS : Ubuntu

Hosting: Cloud

Database: Microsoft SQL Server

WHICH WEB TECHNOLOGIES WILL YOU USE? WHY?

JUSTIFY THE COST.



Web language: Ruby

• web-application framework that includes everything

needed to create database-backed web applications• designed to make programming web applications

easier

•

allows to write less code while accomplishing morethan many other languages and frameworks

WHICH WEB TECHNOLOGIES WILL YOU USE? WHY?

JUSTIFY THE COST.



• Rails was created in 2003 by David HeinemeierHansson and has since been extended by the Rails

core team more than 3,100 contributors

• http://rubyonrails.org/

Books - Agile Web Development with Rails & Crafting Rails 4 Applications.




Rails philosophy includes two major guiding principles:

• DRY - "Don't Repeat Yourself" - suggests that

writing the same code over and over again is a badthing.

• Convention Over Configuration - means that Railsmakes assumptions about what you want to do and

how you're going to do it, rather than requiring youto specify every little thing through endlessconfiguration files.




• open-source software

• application notable for playing a key role in the initialgrowth of the World Wide Web

• run in a process-based, hybrid (process and thread) orevent-hybrid mode, to better match the demands of eachparticular infrastructure

• developed and maintained by an open community of developers under the Apache Software Foundation.

• the software is available for a wide variety of operating systems, including Unix, Linux, Microsoft Windows

APACHE



SECURITY:

• Keep your Web server computer physically secure so

that unauthorized users cannot get to it, turn it off,or take it.

• Secure the Web server computer and all computerson the same network with strong passwords.

• Run a virus checker that monitors inbound andoutbound traffic.

HOW WILL YOU PROVIDE SECURITY AND BACKUP IN

YOUR INFRASTRUCTURE?



• Use a firewall.

• Use event logging and examine the logs frequently for

suspicious activity.• Keep files for your Web application in a folder below

the application root

•

Do not allow users the option of specifying a path forany file access in your application. This helps preventusers from getting access to the root of your server.


YOUR INFRASTRUCTURE?(continued)



• If possible, do not store sensitive information in aplace accessible from the browser, such as hidden

fields or cookies. For example, do not store apassword in a cookie.

• If you must store a user name and passwordsomewhere to use as the database login credentials,

store them in the Web.config file and secure the file with protected configuration





• Use the inherent security of your database to limit who can access database resources.

• Do not store any critical information in cookies. Forexample, do not store a user's password in a cookie,even temporarily. As a rule, do not keep anything in acookie that, if spoofed, can compromise your

application. Instead, keep a reference in the cookie toa location on the server where the information is.





• Set expiration dates on cookies to the shortestpractical time you can. Avoid permanent cookies if

possible.• Consider encrypting information in cookies.





BACKUP: Crashplan+

• backups to local servers or removable media, 30-day

free trials and HIPAA compliance• makes backups to your removable media or servers,

and to any other servers under your control





• Rails support each of our chosen web technologies.

• It is easy to set up and each one is well supported.

• Every web technology that will be used is free of charge, so there is no need to consider financialexpenses

EXPLAIN THE FEASIBILITY AND PRACTICALITY OF

YOUR SETUP.



• a model in the Ruby on Rails framework maps to a tablein a database, and a Ruby file.

•a controller is a component of Rails that responds toexternal requests from the web server to theapplication by determining which view file to render

• a view in the default configuration of Rails is an erb file,

which is converted to HTML at run-time• Ruby on Rails is most commonly not connected to the

Internet directly, but through some front-end webserver.

HOW WEB TECHNOLOGIES MAKE IT HAPPEN
