The costs and time to market benefits of outsourcing business services like payroll, data storage, Customer Relationship Management (CRM) applications, and company websites has been proven to be high for most businesses. This term for outsourced services is most recently known as Software as a Service (SaaS). It needs a lot of capital investment for introducing a new technology because it is an expensive undertaking and can take many months of training, installation and integration before service can be delivered in online. Outsourcing these services to organizations that are experts in the technology can lowers costs, increases uptime, accelerates revenue realization and provides increased flexibility & functionality. As the results are encouraging for these, critical business functions continues to grow and more and more companies are looking for similar opportunities in other operational areas. SaaS Messaging helps in facing the challenges of cost controlling and protecting existing investments meanwhile deploying competitive applications to their customer base. Instead of deploying the equipment in your network, it is housed and maintained by a hosting company. The hosting company owns and manages all of the necessary network equipment and provides it as a service by hosting it in their regional data centers. Subscriber management, maintenance and monitoring are all handled by the hosting service company, which saves the carrier time and money.
