ServiceNow is a SaaS application that provides workflow form-based applications. It is an ideal platform for creating enterprise-level applications giving requesters and fulfillers improved visibility and access to a process. ServiceNow-based applications often replace email by providing a better way to get work done. The book steps through the main aspects of the ServiceNow platform, from the ground up.

To add business logic and control data, and interactivity to user interaction, you will be shown how to code on both server and the client. You will then learn more about the power of tasks, events and notifications. The book will then focus on using web services and other mechanisms to integrate ServiceNow with other systems. Furthermore, you will learn how to secure applications and data, and understand how ServiceNow performs logging and error reporting.

Preface

Upgrading ServiceNow


ServiceNow has a quite unique upgrade capability due to its cloud-based, single-tenant architecture. Releases happen more frequently in ServiceNow than boxed software, with new functionality being released twice a year. However, unlike multi-tenancy architectures, the customer is more in control of when and how often each upgrade occurs.

The release roadmap and methodology that ServiceNow follows is constantly being refined, but as of 2016, the following strategy applies:
