SaaS is a new and alternative way to access software, unlike more traditional access methods. Normally, SaaS refers to a subscription-based model in which the software is hosted in the cloud and accessed through the Internet. Users can usually end their subscription when they no longer need it. Applications are updated and used online with files stored in the cloud instead of computers. SaaS is one of the three main categories of cloud computing, along with infrastructure as a service (IaaS) and platform as a service (PaaS) .SaaS is used in several common business areas, including customer relationship management (CRM) ), document management, accounting, human resources management (HR), management of the service desk, content management and collaboration. SaaS applications are sometimes referred to as web-based software, on-demand software or hosted software.

Characteristics of SaaS
  • A multi-user architecture: a multi-user architecture, in which all users and applications share a single common infrastructure and a centralized code base.
  • Easy customization: the ability of each user to easily customize applications to fit their business processes without affecting the common infrastructure.
  • Better access: improved access to the data of any network device while facilitating the administration of privileges, the use of monitoring data and ensuring that everyone sees the same information at the same time.
Benefits of SaaS
  • No hardware costs: the cloud provider provides the processing power.
  • The use is scalable: you can access storage or additional services on demand without the need to install new software and hardware.
  • Accessible from any location: users are not restricted to a location and can access applications from any Internet-enabled device.
  • No initial installation costs: the applications are ready to use once the user registers.
  • Updates are automatic: updates are often free of changes and are automatically implemented by the software provider.
  • Applications can be customized and have a white label: applications can often be modified to meet the needs and brand of certain customers.
  • Pay for what you use: particularly beneficial when something is only required for a short period.


PaaS includes features of the cloud, such as scalability, availability and multi-tenancy. PaaS reduces the amount of coding required, automates company policy and helps migrate applications to hybrid clouds. With PaaS, users can better manage servers, storage, networks and operating systems. PaaS services are hosted in the cloud and users access them simply through their web browser. PaaS includes infrastructure, storage and network servers, but also middleware, development tools, Business Intelligence (BI) services, database management systems and more. PaaS is designed to support the entire life cycle of web applications, such as construction, testing, implementation, administration and updating.

The PaaS services offered include complementary development facilities, independent development environments, application delivery environments and an open platform as a service. PaaS offers business line software developers a self-service portal to manage the IT infrastructure from centralized IT operations and platforms that are installed on the hardware. Reduce the amount of coding required, automate commercial policy and help migrate applications to the hybrid model.

PaaS helps organizations, specifically developers, realize the benefits of cloud computing by providing a fast and scalable way to host applications in the cloud. Greater efficiency through greater use of user productivity resources, automation and self-service. Access new and more complete features, such as big data analytics, mobile devices and the Internet of things in the background and machine learning. Faster development cycle and time to market. Greater platform scalability

Benefits of PaaS

PaaS development tools can reduce the time it takes to code new applications with precoded application components integrated into the platform, such as workflow, directory services, security functions, search, etc. Platform-as-a-service components can provide your development team with new capabilities without the need to add staff with the required skills. Some service providers provide development options for multiple platforms, such as computers, mobile devices and browsers that make cross-platform applications faster and easier to develop. A pay-per-use model makes possible that people or organizations use sophisticated Business Intelligence and development systems and analytical tools that they can not buy directly.

Because the development environment is accessed through the Internet, development teams can work together on projects, even when team members are in remote locations. PaaS provides all the capabilities you need to support the complete life cycle of the web application: creation, testing, implementation, administration and updating within the same integrated environment.


LaaS is one of the three main categories of cloud computing services, along with software as a service (SaaS) and platform as a service (PaaS). IaaS is an effective model for temporary, experimental or unexpectedly changing workloads. The IaaS provider also provides a range of services to accompany these infrastructure components. These can include detailed billing, monitoring, access to records, security, load balancing and clustering, as well as storage recovery capacity, such as backup, replication and recovery. AI cloud providers provide these resources on demand from their large groups of equipment installed in the data centers. It also includes the delivery of operating systems and virtualization technology to manage resources. IaaS provides the underlying operating systems, security, networks and servers to develop these applications, services and deploy development tools, databases, etc. IAaS providers generally have the latest storage technology, servers and most powerful networks to meet the needs of their customers.
