What is ServiceNow?
ServiceNow is a Cloud-Based Platform used to manage and automate business processes.
In simple words:
ServiceNow helps organizations automate repetitive business processes and manage IT services through a centralized platform.
ServiceNow can be used for activities such as:
- Incident Management
- Change Management
- Request Management
- Problem Management
- Knowledge Management
- Workflow Automation
- Reporting
- Configuration
- Customization
- Integrations
Therefore, ServiceNow should not be considered only a Ticketing Tool. It is a broader business process automation and application platform.
What is ITSM?
ITSM stands for IT Service Management.
ITSM is used to manage IT services and related processes within an organization.
Some of the important ITSM processes include:
Incident Management
Used to manage incidents or interruptions affecting IT services.
Change Management
Used to manage changes in an IT environment in a controlled way.
Request Management
Used to manage requests raised by employees or customers.
Problem Management
Used to identify and manage the underlying causes of recurring incidents.
Knowledge Management
Used to create, manage, and share Knowledge Articles.
ServiceNow ITSM provides a structured way to manage these processes.
Why is ServiceNow Called a Cloud-Based Platform?
ServiceNow is delivered as a Cloud-Based Application.
A cloud-based application is hosted in a cloud environment and accessed over the Internet.
In a simple model:
User → Internet → ServiceNow Cloud → ServiceNow Application
Users generally access ServiceNow through:
- Internet Connection
- Web Browser
- Laptop/Desktop/Computer
This means users can work with their ServiceNow instance through a browser instead of installing a traditional desktop version of the platform.
What is Cloud?
Cloud can be understood as a computing environment where infrastructure, applications, and other resources are made available over a network, commonly through the Internet.
Cloud environments can provide:
- Virtual Machines
- Virtual Servers
- Computing Resources
- Storage
- Hosted Applications
A simple example is a web application that is hosted in a remote cloud environment and accessed through a browser.
Types of Cloud Service Models
There are three major Cloud Service Models:
- IaaS – Infrastructure as a Service
- PaaS – Platform as a Service
- SaaS – Software as a Service
These concepts provide useful background knowledge for understanding cloud-based platforms such as ServiceNow.
IaaS – Infrastructure as a Service
IaaS stands for Infrastructure as a Service.
IaaS provides infrastructure resources that organizations can use to build and host applications.
A simple way to remember it is:
IaaS = Infrastructure
The training session explains IaaS using a raw-material example. Just as raw materials are required to prepare something, infrastructure resources are required to build applications.
Examples of IaaS
- Amazon EC2
- Microsoft Azure
- Google Compute Engine
PaaS – Platform as a Service
PaaS stands for Platform as a Service.
PaaS provides a platform that developers can use to:
- Build applications
- Develop code
- Deploy applications
- Use platform services
A simple way to remember it:
PaaS = Platform for Development
Example
Google App Engine
PaaS allows developers to focus more on application development without having to manage the entire underlying infrastructure themselves.
SaaS – Software as a Service
SaaS stands for Software as a Service.
SaaS provides Ready-to-Use Software over the Internet.
A simple way to remember it:
SaaS = Software
For example, when a user accesses Gmail, they do not need to build or manage the Gmail application themselves. They simply use the software provided by the service.
The session uses examples such as Gmail and other cloud-based services to explain this concept.
IaaS vs PaaS vs SaaS
| Cloud Model | Full Form | Main Purpose |
|---|---|---|
| IaaS | Infrastructure as a Service | Provides infrastructure |
| PaaS | Platform as a Service | Provides development platform |
| SaaS | Software as a Service | Provides ready-to-use software |
Easy Trick
IaaS → Infrastructure
PaaS → Platform
SaaS → Software
Is ServiceNow SaaS or PaaS?
This is one of the common questions beginners ask.
ServiceNow can be understood from both perspectives.
ServiceNow as SaaS
ServiceNow provides many Out-of-the-Box (OOTB) applications and modules.
Examples include:
- Incident
- Change
- Request
- Problem
- Knowledge
Organizations can use these standard applications and configure them according to their needs.
ServiceNow as PaaS
ServiceNow also provides a platform where developers and administrators can:
- Configure applications
- Customize applications
- Build functionality
- Create workflows
- Add business logic
- Develop scripts
- Integrate external systems
- Create reports
Therefore, the training session explains ServiceNow from both SaaS and PaaS perspectives.
What is Out-of-the-Box Functionality in ServiceNow?
Out-of-the-Box (OOTB) means functionality that is already provided by ServiceNow.
Instead of developing everything from scratch, organizations can use existing functionality.
Examples:
- Incident Management
- Change Management
- Request Management
- Problem Management
- Knowledge Management
This can reduce the amount of custom development required.
ServiceNow Business Process Automation
One of the most important concepts in ServiceNow is:
Business Process Automation
Let’s understand this with a simple example.
Suppose you order a product from an e-commerce website.
The process might be:
Search Product → Add to Cart → Address → Checkout → Payment → Confirmation → Packing → Dispatch → Tracking → Delivery
After placing the order, the customer can track the status without repeatedly calling customer care.
This is a simple example of automating a business process.
The same concept is applied in enterprise environments using ServiceNow.
Real-Time ServiceNow Request Example
Imagine that an employee needs a new laptop.
Manual Process
The employee might:
- Send an email
- Wait for approval
- Contact the Service Desk
- Follow up repeatedly
- Ask for status updates
ServiceNow Process
The same requirement can be managed using ServiceNow:
Employee
↓
Request
↓
Approval
↓
Assignment
↓
Fulfillment
↓
Notification
↓
Closure
The employee can track the request and the organization can maintain the complete process in a structured way.
This is the practical idea behind ServiceNow Business Process Automation.
ServiceNow is More Than a Ticketing Tool
A common misconception is:
“ServiceNow is only a ticketing system.”
That is not the complete picture.
ServiceNow can support:
- Ticket Management
- Process Automation
- Workflow
- Configuration
- Customization
- Business Logic
- Reporting
- Integration
- Application Development
For example, developers can configure an Incident form with fields, validations, business rules, workflows, notifications, and other functionality.

ServiceNow Interview Preparation
One of the most important points for a ServiceNow career is Interview Preparation.
Do not prepare only definitions.
For every topic, prepare these five questions:
1. What is it?
Learn the definition.
2. Why do we use it?
Understand the business purpose.
3. Where do we use it?
Understand the real-time scenario.
4. How do we implement it?
Understand Configuration and Development.
5. Can you give a real-time example?
Be able to explain your practical understanding.
This method helps students move from theoretical knowledge to practical understanding.
Definition vs Real-Time Knowledge
Suppose an interviewer asks:
What is an Incident?
A candidate should not stop at the definition.
The interviewer may continue asking:
- Why do we create an Incident?
- Who can create an Incident?
- How is an Incident assigned?
- How is Priority determined?
- What is SLA?
- How is an Incident resolved?
- How is an Incident closed?
- What happens after resolution?
Therefore:
Definition + Concept + Business Scenario + Implementation Knowledge
is much more useful than definition memorization alone.
ServiceNow Administration
A ServiceNow Administrator typically works with configuration and platform-management activities.
Some examples include:
- Forms
- Fields
- Users
- Modules
- Configuration

ఈ content introductory ServiceNow training session ఆధారంగా structured చేయబడింది.
ServiceNow అంటే ఏమిటి?
ServiceNow అనేది Cloud-Based Platform. ఇది organizationsలో common business processesను manage మరియు automate చేయడానికి ఉపయోగిస్తారు.
Simpleగా చెప్పాలంటే:
ServiceNow = Cloud-Based Platform + Business Process Automation
ServiceNow ద్వారా organizations:
- Incident Management చేయవచ్చు
- Change Management చేయవచ్చు
- Request Management చేయవచ్చు
- Problem Management చేయవచ్చు

ServiceNow ఎందుకు Cloud-Based Platform?
ServiceNow ఒక Cloud-Based Application / Platform.
Cloud-Based Application అంటే Cloud environmentలో host చేసిన application. దీన్ని Internet ద్వారా access చేయవచ్చు.
Simple flow:
User → Internet → ServiceNow Cloud → ServiceNow Application
ServiceNow access చేయడానికి సాధారణంగా:
- Internet Connection
- Web Browser
- Laptop / Desktop / Computer
ఉంటే సరిపోతుంది.
అంటే ServiceNowని browser ద్వారా access చేసి platformపై పని చేయవచ్చు.
Cloud అంటే ఏమిటి?
Simpleగా అర్థం చేసుకోవాలంటే:
Cloud అనేది Internet ద్వారా computing resources మరియు applicationsని access చేసే environment.
Cloud environmentలో:
- Virtual Machines
- Virtual Servers
- Computing Resources
- Storage
- Applications
వంటివి available ఉంటాయి.
ఒక applicationని local systemలో host చేయకుండా remote infrastructureలో host చేసి Internet ద్వారా access చేయవచ్చు.
Cloud Service Models అంటే ఏమిటి?
Cloudలో ముఖ్యమైన మూడు service models ఉన్నాయి:
- IaaS – Infrastructure as a Service
- PaaS – Platform as a Service
- SaaS – Software as a Service
ఈ concepts ServiceNowని అర్థం చేసుకోవడానికి basic backgroundగా ఉపయోగపడతాయి.
IaaS – Infrastructure as a Service
IaaS = Infrastructure as a Service
IaaSలో application build మరియు host చేయడానికి అవసరమైన infrastructure resources అందిస్తారు.
Simpleగా:
IaaS = Infrastructure
Trainer sessionలో దీన్ని Raw Material exampleతో explain చేశారు.
మనకు ఒక product తయారు చేయాలంటే raw material అవసరం.
అలాగే application build చేయాలంటే infrastructure అవసరం.
IaaS Examples
- Amazon EC2
- Microsoft Azure
- Google Compute Engine
IaaSలో infrastructure resourcesను పొందుతాం.
PaaS – Platform as a Service
PaaS = Platform as a Service
PaaS developersకి application build మరియు deploy చేయడానికి ఒక platformని అందిస్తుంది.
PaaS ద్వారా:
- Code develop చేయవచ్చు
- Applications build చేయవచ్చు
- Applications deploy చేయవచ్చు
- Platform servicesని use చేయవచ్చు
Simpleగా:
PaaS = Platform for Development
Example
Google App Engine
PaaS ఉపయోగించడం వల్ల developers underlying infrastructure management కంటే application developmentపై ఎక్కువగా focus చేయవచ్చు.
SaaS – Software as a Service
SaaS = Software as a Service
SaaS అంటే already available ఉన్న Ready-to-Use Softwareని Internet ద్వారా use చేయడం.
Simpleగా:
SaaS = Software
ఉదాహరణకు Gmail.
Gmailని use చేయడానికి మనమే application develop చేయాల్సిన అవసరం లేదు.
Login → Use Application
అంతే.
Sessionలో Gmail మరియు ఇతర cloud servicesని SaaS concept explain చేయడానికి examplesగా ఉపయోగించారు.
IaaS vs PaaS vs SaaS
| Model | Full Form | Simple Meaning |
|---|---|---|
| IaaS | Infrastructure as a Service | Infrastructure |
| PaaS | Platform as a Service | Development Platform |
| SaaS | Software as a Service | Ready-to-use Software |
Easy Memory Trick
IaaS → Infrastructure
PaaS → Platform
SaaS → Software
ServiceNow SaaSనా? PaaSనా?
ఇది ServiceNow beginnersకి common question.
Training sessionలో ServiceNowని రెండు perspectivesలో explain చేశారు.
ServiceNow as SaaS
ServiceNowలో already చాలా Out-of-the-Box (OOTB) applications మరియు modules ఉంటాయి.
ఉదాహరణలు:
- Incident
- Change
- Request
- Problem
- Knowledge
Organization వీటిని standard functionalityగా use చేయవచ్చు.
ServiceNow as PaaS
ServiceNow ఒక development platformగా కూడా ఉపయోగించవచ్చు.

- Integrations implement చేయవచ్చు
అందువల్ల training sessionలో ServiceNowని SaaS + PaaS perspectivesతో explain చేశారు.
Out-of-the-Box (OOTB) Functionality అంటే ఏమిటి?
Out-of-the-Box లేదా OOTB అంటే ServiceNow already provide చేసే standard functionality.
ఉదాహరణలు:
- Incident Management
- Change Management
- Request Management
- Problem Management
- Knowledge Management
అంటే ప్రతి functionalityని మొదటి నుంచి code చేయాల్సిన అవసరం ఉండదు.
Existing functionalityని use చేయవచ్చు.
Business requirementకి అనుగుణంగా అవసరమైతే configuration లేదా customization చేయవచ్చు.
Business Process Automation అంటే ఏమిటి?
ServiceNowలో చాలా important concept:
Business Process Automation
ఒక organizationలో repeatedగా జరిగే business activitiesని system ద్వారా automate చేయడం.
దీన్ని అర్థం చేసుకోవడానికి ఒక E-Commerce example చూద్దాం.
E-Commerce Automation Example
Suppose మనం Amazonలో product order చేస్తున్నాం.
Process:
Search Product
↓
Add to Cart
↓
Enter Address
↓
Checkout
↓
Payment
↓
Order Confirmation
↓
Packing
↓
Dispatch
↓
Tracking
↓
Out for Delivery
↓
Delivered
Order place చేసిన తరువాత customer statusని systemలో track చేయగలడు.
ప్రతి చిన్న update కోసం customer careకి call చేయాల్సిన అవసరం ఉండదు.
ఇదే Business Process Automationకు simple example.
ServiceNowలో Real-Time Request Example
ఒక employeeకి కొత్త Laptop కావాలని అనుకుందాం.
Manual Process
Employee:
- Email పంపాలి
- Manager approval కోసం wait చేయాలి
- Service Deskని contact చేయాలి
- Status కోసం follow-up చేయాలి
- మళ్లీ email పంపాలి
ServiceNow Process
ServiceNowలో:
Employee
↓
Create Request
↓
Manager Approval
↓
Assignment
↓
Fulfillment
↓
Notification
↓
Closure
Employee request statusని track చేయగలడు.
Organizationకి complete process visibility వస్తుంది.
ఇదే ServiceNowలో Business Process Automation.
ServiceNow కేవలం Ticketing Tool కాదు
కొంతమంది:
“ServiceNow అంటే Ticketing Tool”
