2. Challenges with Legacy applications
 Legacy Website 1
 No basic Framework used so there are problems in implementing even simple
things like Internationalization .
 If a new trending functionality comes whole code from scratch need to be
written (Involves Time + Development Cost).
 Basic UI Compatibilities like Responsive themes and Compatibility across
browsers , General Templets are needed .
 Not properly SEO compliant.
 For operational task major code changes need to be done example To add
new Operator whole new tables need to be created .

3. Current Challenges…
 Legacy Website 2
 Multi-tenancy support is not there .
 Support for hierarchical Organization structure is not there.
 Scalability and Security Issues .
 Template support for easy UI customization
 New Features need to be developed from scratch .
 Time between New feature Idea - Development – Deployment is too much .

Criteria of selection : Most used , Most discussed ,Most popular and comes is
category of best available Commonly used CMS Products

6. WordPress
 WordPress is a free and open-source content management system (CMS)
based on PHP and MySQL .
 WordPress was used by more than 23.3% of the top 10 million websites .
 Many security issues have been uncovered in the software such as a CSRF,
LFI, RFI, XSS or SQL injection .
 Why WordPress Is Not a Good Ecommerce Platform . Its popularity can
also be the downfall of WordPress. Because of its large installed base,
WordPress is constantly under attack from various kinds of hacking attacks.
Sure they release upgrades all the time, but who wants to live under constant
threat of getting hacked?
 When your ecommerce business grows, and you have to process a large
number of orders, the number of concurrent scripts that WordPress executes
can overwhelm many web servers.

7. SharePoint
 SharePoint is a web application platform in the Microsoft Office server suite
basically used for collaborating data, managing documents and files,
creating websites .
 SharePoint have traditionally been deployed for internal use in mid-size
businesses and large departments

Server .Mostly SharePoint Server is used for any critical application .
 Total Cost of Ownership of Microsoft SharePoint ($8/month per user + Per
server cost 5000 $).
 SharePoint is a closed source.
 SharePoint locked with Microsoft and .net framework.

8. Joomla
 Joomla is a free and open-source content management system (CMS) for
publishing web content. It is built on a model–view–controller web application
framework that can be used independently of the CMS.
 It is estimated to be the second most used content management system on
the Internet after WordPress .
 It doesn’t require the high level of technical experience to run .
 Joomla is basically for Less Traffic sites .
 If you’re setting up a site which you believe will grow rapidly from day one,
and require extensive features for the users, Drupal may be more in line with
what you need. Joomla is great for those somewhere in the middle .

9. Drupal
 Drupal is a free and open-source content-management framework written in
PHP and distributed under the GNU General Public License. It is used as a
back-end framework for at least 2.1% of all Web sites worldwide

features .
 As of October 2014 the Drupal website lists more than 28,200 free modules
 Security - Drupal's policy is to announce the nature of each security
vulnerability once the fix is released.
 Learning curve: Some users describe Drupal as being difficult to master , if
we can’t hire someone who knows it, it may not be the best choice..
