Using What We've Learned

This month Mr. Lerner shows us how to set up a web site using many of the techniques he's taught us over the past months.
Summary

Most people do not need to be reminded of their birthdays. And indeed, the use of birthdays in this example was simply for demonstration purposes. Even with the limited information we stored in our database, we can create a bare-bones personalized home page that displays the user's name in the title. With a little more work, we could print a special message on this user's birthday, or an indication of how many days remain until the user's next birthday.

And because we have stored all users' birthdays in our database, we can create applications that access other birthdays on the system. For instance, we could create a CGI program (or a Perl/HTML template) that finds other users on the system with your birthday. The possibilities are endless, and putting the information into templates means that you (as the programmer or webmaster) can concentrate on writing the code necessary to make things run, while the site's editorial and production staffs can make things look pretty and ensure that they are grammatically correct as well.

With that, we end our whirlwind (albeit longer than usual) tour of integrating multiple techniques into a single web site. Web sites based on databases are increasingly popular, for good reason. The largest and best-known web sites combine back-end databases with templates and cookies to give each user a personalized experience; now that you have seen how it can be done, create some on your own sites.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
