Dynamic Graphics and Personalization

A continuation of the discussion on creating graphics dynamically on the Web.
Conclusion

Last month, we saw how to create simple dynamic stock graphs using the GIFgraph package. This month, we saw how such dynamically created graphics can fit into a larger application, allowing users to see information about their stock portfolios. The combination of a relational database, mod_perl and GIFgraph makes it possible to create such a simple application in under 400 lines of code. You can undoubtedly think of many other applications in which dynamically created graphics would be useful—let your imagination go wild!

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.
