Overview of this book

GeoServer is open source, server-side software written in Java that allows users to share and edit geospatial data. In this book, you'll start by learning how to develop a spatial analysis platform with web processing services. Then you'll see how to develop an algorithm by chaining together geospatial analysis processes, which you can share with anyone in the world. Next you'll delve into a very important technique to improve the speed of your map application—tile caching. Here, you'll understand how tile caching works, how to develop an effective tile cache-supported web service, and how to leverage tile caching in your OpenLayers web application. Further on, you'll explore important tweaks to produce a performant GeoServer-backed web mapping application. Moving on, you'll enable authentication on the frontend and backend to protect sensitive map data, and deliver sensitive data to your end user. Finally, you'll see how to put your web application into production in a secure and user-friendly way. You'll go beyond traditional web hosting to explore the full range of hosting options in the cloud, and maintain a reliable server instance.

Monitoring the GeoServer instance

In the previous section, you learned about hosting options for your GeoServer instance. In this section, you'll learn how to make sure the instance remains healthy, and how to detect and remedy errors if something goes wrong. You'll learn about logging and all the different logs associated with GeoServer and other app components. You'll learn how to use the GeoServer monitoring plugin. Finally, we'll cover some other software for monitoring the infrastructure supporting our apps.

Server software creates log files to provide administrative insight into the operation of the software. The server may use a single log file, or it may use additional log files to divide up categories of events – access versus errors, for instance. While the access log could be used to audit server traffic, the error log could be used to diagnose...
