Introduction to ServiceNow
If you are reading this book, it is probably because your company is planning to implement and customize the ServiceNow platform or you want to build a career around the fastest growing enterprise cloud platform. ServiceNow is a SaaS platform offered by ServiceNow, Inc. and used by global corporations such as GE, Dell EMC, NetApp, Yahoo, Google, Aegis, Deutsche Bank, AstraZeneca, Red Hat, Siemens, University of San Francisco, Sony Pictures Entertainment, Intuit, Moody's, Diageo, and so on. For the purpose of this book, we are going to assume that you work at ABCD, Inc. and your company's management has asked you to build a custom application on top of the ServiceNow platform.
ServiceNow allows companies to manage processes and create custom applications using a single system of record framework - meaning every application and all data stored in the platform follows the same framework and basic structure. ServiceNow platform comprises key product features such as Service Management, IT Operations Management, Application Development, IT Business Management, Human Resources, Customer Service, and Security.
Service Management
: Offers features used by your IT Service Desk to manage ITIL processes
such as
Incident Management, Change and Release Management, Problem Management, Service Level Management, Service Catalog, Knowledge Management, and Configuration and Asset Management along with features like reporting and administration, which extend across other features as well.
IT Operations Management
: Includes applications
such as
Discovery, Service Mapping, Event Management, Orchestration and Cloud Management.
Application Development
: Includes the core Platform and app development features
such as
Custom Applications, APIs, Portal Designer and Integration tools.

such as
Performance Analytics, Financial Management, Project Portfolio Management, Demand Management, Resource Management and Application Portfolio Management.
Security
: It includes features and applications related to Security Operations and
Governance, Risk and Compliance
(
GRC
)
Customer Service
: It includes applications such as Customer Service Management, Field Service Management and Knowledge Management.
Human Resources
: It includes the HR Service Management application.
In this book, we will be covering topics related to application development and customizing and extending features of Service Management applications such as Incident Management. As ServiceNow is a cloud-based platform, we do not usually need to install any special software on a client system. We can access any ServiceNow instance easily from anywhere using a computer or mobile with internet connectivity and the latest browser such as Microsoft Edge, Internet Explorer, Firefox, or Google Chrome. For administration and Development purposes, it is recommended that you use a desktop with the latest version of Chrome, which is what we will be using throughout this book to access our instance.
This chapter will help you get started with ServiceNow and gain access to a free developer instance from ServiceNow developer portal and understand the basics of ServiceNow such as UI, Users, and out-of-the-box applications and features.
This chapter will cover the following topics:
Creating a ServiceNow developer account
Launching a developer instance
Understanding the ServiceNow platform login process
Understanding the ServiceNow user interface
An introduction to Service Management Applications
ServiceNow platform architecture
Creating a developer account
ServiceNow, Inc. offers developers a free instance of their cloud-based platform. To be able to develop a custom application, you first need to have your own instance of the ServiceNow platform. You can create a developer account and request a free instance by visiting the ServiceNow developer portal site at: https://developer.servicenow.com:
The registration process for the ServiceNow developer portal is fairly simple. You can click on the REGISTER link in the upper-right, if you are not already registered, and fill in your name, e-mail, and choose a password to complete your registration. Once you verify your email and are registered, you can log in to the ServiceNow developer portal and request an instance by clicking on the Request Instance button, as shown in the following screenshot:
Requesting a new ServiceNow instance
You will be presented with a modal window, like the one shown in the following screenshot, to select a version of the ServiceNow instance you wish to launch. For the purpose of this book, we will be launching an instance running the Istanbul version of the ServiceNow platform. You can also select the latest version of the ServiceNow platform, which is Jakarta:
It may take a few minutes for the developer portal to assign you an instance. Once the instance is available, you will be presented with details of your instance - such as the URL of the instance, the System Administrator's username (by default admin), and an alphanumeric password. Make sure to save this information for future reference:
You will also be presented with the credentials to log in to your instance, as shown in the following screenshot:
Logging in to your instance
Now that you have your own personal developer instance, in the ServiceNow developer portal, you can click on the instance URL link to open and log in to your instance using the admin user credentials, as shown in the following screenshot:
Enter your User name and Password to log in to your instance, and leave the Rememberme checkbox checked only if you trust others who share your computer. If you are logging in to your instance for the very first time, it will prompt you to change your password. Every ServiceNow instance's URL is different. Instance settings, users, passwords, roles, applications, modules, tables, UIs, scripts, and so on available for one instance are unique to that instance. They can, however, be copied from one instance to another.
The first time you log in as admin, you are taken to the System Administrator homepage (Dashboards), like the one shown in the following screenshot:
Understanding the ServiceNow platform user interface
Just like any web-based application, we interact with the ServiceNow platform's application and modules through the user interface using a web browser. The version of UI that comes with the Istanbul release of ServiceNow is referred to as UI16. There are three main components of UI16: Banner Frame, Application Navigator, and Content Frame.
Components of the user interface
The various components of the user interface are explained here:
Banner Frame (top header)
: The banner frame appears at the top of the interface. This is where you see the logo, global navigation, logged-in user's info, search and other tools, and a settings (gear/cog) icon at the extreme right. This settings gear icon is extremely useful for developers as it is used quite frequently during development:
Application navigator (left navigation bar)
: This is where navigation links to different ServiceNow platform applications and modules are visible. It has a text filter box at the top, which allows us to filter through available navigation links. There are three tabs available in the left navigation bar:
The
Applications
tab contains a list of all of the applications and modules the logged in user has access to. Based on the user's role, each link has an edit icon and inactive star icon to its right. The edit link can be used to navigate to the edit module page, and the star icon can be clicked on to add or remove navigation entries to user favorites.
The
Favorites
tab lists all navigation links and items the logged in user has added to their favorites.
The
History
tab lists navigation links and items the logged in user has recently accessed.
Content Frame:
This is the main section of the user interface where pages, forms, list of records, dashboards,
Homepages
of all applications, and modules are loaded.
It is possible to switch back to an earlier version of the user interface (UI15) by clicking on the settings gear icon in the far right of the Banner Frame, which will open up the System Settings modal window (more on this on next page), and then clicking on the Switch to U15 button in the upper-right of the modal window. To switch back to U16, again click on the settings gear icon, and click on the Switch to U16 button:
Version 15 of the UI features The Edge, which has been replaced by the Favorites (left-navigation) tab in version 16 of the UI, as shown in the following screenshot:
System settings
The System Settings modal window is accessible (in UI16) by clicking on the settings gear icon in the Banner Frame. When you are logged in as System Administrator or a delegated developer, you will have the following settings available:
General
: Here you can change your time zone, view a printable version of the content frame, and change a few accessibility-related settings.
Theme
: Allows you to select and change your UI's theme color.
Lists
: Here you can change settings related to a list of records module pages:
Wrap longer text in list columns
: If enabled, breaks long text into lines in order to minimize horizontal scrolling in the list of records module pages.
Forms
: This tab allows you to change how your Form UI loads and work:
Tabbed forms
: If enabled, all related lists and sections on the form show up in tabs in all forms.
Related list loading
: Allows changing how related lists load in the form. We can choose to load related lists
With the Form
,
After the Form,
or
On-Demand
.
Notifications
: This tab allows users to enable or disable mobile, desktop (web), e-mail, and audio notifications.
Developer
: This tab is only available to users with an admin role or a delegated developer. This tab allows developers to select their current
Application
and working
Update Set
. The following settings are available under the
Developer
tab:
Application picker drop-down
: Allows selecting an application scope and marking it as active. This prevents developers from making modifications to any other application other than the one that is currently selected. One ServiceNow instance can have more than one application scope defined but a user can work only on one of the scopes at any given time.
Show application picker in header
: If enabled, shows application picker drop-down in the banner frame. We will keep this setting enabled for the rest of our chapters.
Update Set picker drop-down
: Allows selecting an
Update Set
and marking it as active.
Update Sets
are like containers, which record changes to the selected
Application
scope and allows easy migration of changes to other instances and rollbacks. One application scope can have more than one
Update Sets
defined but only one marked as active.
Show update set picker in header
: If enabled, shows the
Update Set
picker drop-down in the banner frame. Keep it enabled for the rest of our chapters.
JavaScript Log and Field Watcher
