Software as a Service (SaaS) is a cloud computing model that allows businesses and individuals to access software applications via the internet, on a subscription basis, without the need to install or maintain them locally. SaaS applications are hosted on the provider’s infrastructure, which reduces the need for extensive hardware, software maintenance, and manual updates.
SaaS has revolutionized how businesses operate by providing flexible, scalable, and cost-effective software solutions. Whether it’s for customer relationship management (CRM), enterprise resource planning (ERP), data storage, or other essential business functions, SaaS has become the backbone of many modern organizations’ IT strategies.
