Presently, the cloud service offered runs on multi-tenant architecture like Salesforce, AWS, Oracle, Azure, etc. The multi-tenant architecture provides a single instance that serves multiple customers. This leads to complex databases that require huge maintenance costs, and sometimes the resources may not be available to the customers. ServiceNow offers the latest by adapting multi-instance architecture.
In ServiceNow platform architecture, the packaged solutions are represented by applications designed to deliver and help manage business processes like Change Management, Incident Management, Knowledge Management, and Problem Management.
The multi-tenant architecture uses a single instance of software application services, tenants, or multiple customers. This architecture is economical because software development and maintenance costs are shared.
The updates are shared with all of its 'tenants' in a multi-tenant architecture only once. A software-as-a-service (SaaS) vendor can run applications and databases on a one-to-one instance to provide web access to multiple customers. In this scenario, every customer's data is isolated and invisible to other tenants. This way, the data of the customers are safe and secure.
Infrastructure as a service (IaaS) is a fully automated feature that offers computing resources that a service provider owns and offers storage and networking capabilities to the customers on demand. Resources are measured in real-time and metered by use. Resources can be single-tenant or multi-tenant and are maintained by the service provider.
In the IaaS model, IT infrastructure that includes server, storage, and networking resources are managed by cloud providers and delivered to the organizations virtually. The benefits of IaaS are it makes the workload flexible, more accessible, faster, and cost-effective.

Platform as a service (PaaS) offers an entirely cloud-based environment for the development and deployment of resources that enable the delivery of simple to complex cloud-based applications. The resources can be purchased from a cloud service provider on a pay-as-you-go basis and accessed over a secure Internet connection.
Like IaaS, PaaS includes infrastructure such as servers, storage and networking, development tools, middleware, business intelligence (BI) services, database management systems, and more. The design of PaaS supports a complete web application lifecycle: building, deploying, testing, managing, and updating. PaaS is cost-effective, thereby reducing the complexity of buying and managing software licenses, development tools, other resources, and the underlying application infrastructure and middleware. Here everything is governed by the cloud service provider.
Software-as-a-Service (SaaS) is a software license model to access the software on a subscription basis, and the software could be located on external servers.
Software-as-a-Service can be accessed through a web browser, and the users can log into the system with a username and password. This service does not require the software to be installed on a computer; instead, it can be accessed virtually.
The multi-tenant architecture allows SaaS vendors to serve even the small customers, with dedicated infrastructure, to large enterprises with cloud access and unlimited computing resources. One of the critical features of the cloud is elasticity which is a considerable benefit of multi-tenancy. Before the existence of SaaS, companies had to purchase costly compact disks that contained the updates and download them into their systems.
ServiceNow supports several applications. Some of them are Resolving Security Threats, IT Service Desk, HR Delivery Service, Customer Service, and Business Applications.

Though there are many sophisticated security management mechanisms available in the marketplace for threat detection, most companies face the backbreaking task of resolving the security issue when there is a security breach. ServiceNow is well known for its structured workflows that prioritize risks based on severity and their impact on the organization. Generally, it would take up to 45 minutes to conduct the threat research manually and using spreadsheets. This time can be reduced to over 20 seconds by using the automated tools provided by the ServiceNow platform.
ServiceNow Security Operations focus on security incidents that pose a threat to their organization. Security Operations designs predefined workflows that include routing the issue to the appropriate person or team for revising and automating threat detection. Security Operations relates the event data with the ServiceNow Configuration Management Database (CMDB) and uses this data which can be considered part of a risk score calculation to maintain the priority.
