Editor's note

Modern, distributed applications feature significantly more complex component interactions than the legacy monoliths with which IT organizations are familiar, and virtualized infrastructures, such as cloud platforms, operate differently than physical servers. Organizations must rethink their application performance improvement methods.

The application performance management (APM) umbrella encompasses monitoring, error resolution and multiple IT and non-IT departmental responsibilities. Start with an evaluation of available APM tools, based on what your organization needs and its budget, and take into account monitoring focuses, metrics and alert preferences. Proceed with a close interrogation of your organization's processes and methodology -- who is involved and who should be.

1Fine-tune processes and methodology

Application performance improvement goes beyond simply having the right tool to capture ops data. Learn how to direct attention to the most likely sources for a bottleneck, which team members to involve in the process and how to ensure that cloud applications float along smoothly.

2Comprehensive monitoring is key for APM

An organization committed to application performance improvement must be equally committed to a monitoring setup that tracks the right metrics and sends out the right alerts. It's unlikely that any tool can do these things perfectly off the shelf; these tips aid in customization and tuning.
