Cloud is a buzzword nowadays. Many organizations are exploring ways and means to move the entire or a part of their applications on cloud. One can make use of the ready-to-use SaaS service and use services like Cloud ERP, Human Capital Management, and Oracle CX.
Use of complete SaaS products is possible for smaller organizations or start-ups. Bigger organizations which have already invested in huge infrastructure, using very complex nature of business process with vast customizations, find it difficult to move their entire application footprint to Cloud platforms in one go. Hence, most of the organizations prefer to run in a coexistence model.
