As we have seen in the previous chapters, everybody will feel that Sitecore is clearly designed with extensibility as a high priority. Developers can extend the Sitecore backend architecture using a variety of techniques. We can have multiple approaches to achieve one customization; it's just a matter of which one is the best suited.
Sitecore uses the Sitecore.config
file almost like a dependency injection container. Most of the backend operations are defined in this file and are configurable and extendable as per requirement. You can override almost any feature defined in this configuration file such as pipelines, processors, handlers, agents, events, providers, event handlers, hooks, and others. You will also learn how to use a patch configuration file to override the Sitecore.config
configurations.
Apart from this, we will also cover some more techniques of extending the Sitecore architecture in the next chapter.
