Learn how to implement middleware into the mod_perl/Apache design mix.
Conclusion

This month, we looked at the reasons behind three-tiered architectures and started to look into a basic implementation of an application that uses this architecture. As you can see, we can already create small text-mode applications. Next month, we will complete our implementation, giving us the skeleton for a simple appointment book using mod_perl/Mason and PostgreSQL. We will also discuss issues regarding the scalability of three-tier solutions, as well as some of the pitfalls.

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.
