Software as a Service (SaaS)

Software as a Service, or SaaS, is a cloud-based service where users can access software hosted by a provider. The provider takes care of the servers, databases, and code that make up the application. They also handle security, availability, and performance. Users can access these applications over the internet without worrying about maintaining or updating the infrastructure.

Core Business Processes Supported by SaaS

SaaS supports essential business functions like email and collaboration through services like Microsoft’s Office 365 and Google’s Gmail. It also supports Customer Relationship Management (CRM) with tools like NetSuite CRM and Salesforce, Human Resource Management with Workday and SAP SuccessFactors, as well as financial management, billing, and collaboration.

Platform as a Service

Platform as a Service (PaaS)

Platform as a Service, commonly referred to as PaaS, is a cloud computing model that provides customers with a complete platform to develop, deploy, manage, and run applications. The PaaS provider hosts everything: servers, networks, storage, operating systems, application runtimes, APIs, middleware, databases, and other tools at their data center. The provider also takes responsibility for the installation, configuration, and operation of the application infrastructure, leaving the user responsible only for the application code and its maintenance. Customers pay for this service on a usage basis and purchase resources on demand.

Infra Structure as a Service

Infrastructure as a Service (IaaS)

Infrastructure as a Service, or IaaS, is a cloud computing model that provides essential computing, networking, and storage resources over the internet on a pay-as-you-go basis. The cloud provider manages the infrastructure components and virtualization layer, allowing users to focus on their applications.

Virtual Machines and Provisioning

In an IaaS environment, users can create virtual machines (VMs) in various regions and zones. These VMs come with a choice of operating systems, enabling users to install applications and run workloads. Users can also manage storage and backups, and monitor performance and usage.
