Business Benefits of PaaS

The potential cost savings of IaaS are clear — you can rent compute resources only when you need them. So, you pay only for what you use. PaaS can operate in a similar fashion to IaaS by allowing companies to use a PaaS service during development and deployment, instead of having to purchase many different independent tools.

In a hybrid environment, when the same PaaS environment can support both public and private services, organizations can benefit by this level of flexibility and agility. By providing a homogenous platform, workloads can easily be moved from a private cloud to a public cloud for deployment and efficient scaling. This allows organizations to have a high degree of control on where a particular application is running. Some of the business benefits of PaaS include reduced costs and increased speed of development and deployment.

Reducing costs

By providing the underlying software infrastructure, PaaS can reduce organizational costs. PaaS reduces many of the costs involved with the traditional application development and deployment model, including the ones we discuss here.

Server and storage overhead

Writing and testing new programs are compute-intensive and require large amounts of server and storage space. Typically, once the development and deployment stages are complete, a company’s server and storage space lie largely dormant. This underutilized computing capacity requires power, cooling, and maintenance to run, as well as floor space. ...
