It is time for IT to leave the past behind and embrace the future. The time of specially, sometimes elaborately maintained systems within companies and large server rooms is already years past. Software as a Service is the keyword that keeps coming up. Many people ask themselves what Software as a Service, abbreviated SaaS, is and why it has become so popular.
Software as a Service
Software as a Service (SaaS) is a software model in which a third-party provider hosts applications and makes them available to customers, usually for a fee, via the Internet. Along with Infrastructure as a Service (IaaS) and Platform as a Service (PaaS), SaaS is one of the three main categories of cloud computing.
SaaS is closely related to the Application Service Provider ( ASP ) and delivery models for on-demand computing software. The management model for hosted applications of SaaS is similar to ASP, where the provider hosts the customer's software and delivers it over the Internet to authorized end users.
When new features or functions are introduced, they are introduced for all customers. Depending on the Service Level Agreement (SLA), customer data for each model can be stored locally, in the cloud or both (local and cloud). Organizations can integrate SaaS applications with other software using Application Programming Interfaces (APIs). For example, an organization can write its own software tools and use the SaaS provider's APIs to integrate those tools into the SaaS offering. An example of this is the MyOdoo Nextcloud Connector.
The advantages of Software as a Service
With SaaS, organizations no longer need to install and run applications on their own computers or in their own data centers. This eliminates the cost of purchasing, deploying and maintaining hardware, as well as licensing, installing and supporting software. Other advantages of the SaaS model are:
Instead of purchasing software or additional hardware, customers subscribe to a SaaS offering.
As a rule, this service is paid monthly according to the pay-as-you-go system. By converting costs into recurring operating expenses, many companies can achieve better and more predictable budget planning. Users can also cancel SaaS offerings at any time to stop these recurring costs.
Cloud services such as SaaS offer high vertical scalability, allowing customers to access more or fewer services or features as needed.
Instead of buying new software, customers can rely on a SaaS provider to perform updates automatically. This further reduces the burden on internal IT staff.
Because SaaS applications are delivered over the Internet, users can access them from any Internet-enabled device and location.
