PaaS

“Platform as a service” is software that facilitates development, deployment and operations for IT on a private infrastructure or behind a firewall. Both public and private PaaS lets developers code, test, design and manage their organisations’ cloud-based systems. Developers have greater control over the more nimble private PaaS, but that control comes with added responsibilities and expenses. The hardware and software needed to support it must be bought, set up and maintained by the customer’s IT department. Some of the differences and benefits include the ability to scale to a public cloud or become a hybrid cloud when extra processing is needed and the ability to develop cloud applications that could not exist in the cloud for security reasons. Private PaaS also consolidates a company’s cloud development into one environment. Nevertheless, it attracts customers with concerns about shadow IT and rogue applications developed on public PaaS.
