The acronym SaaS stands for Software as a Service. This software distribution model facilitates access to applications hosted in the cloud via the internet, eliminating the need for local installations. Users typically pay a subscription fee to utilize the software on-demand, providing flexibility and scalability. SaaS applications are often updated automatically and can be accessed from various devices. This model reduces the cost associated with maintaining hardware and software, making it an attractive option for businesses looking to streamline operations while ensuring up-to-date functionality and security.
