The users do not need to install the software applications on the computer due to which there is lesser need for support and maintenance. The billing and payment is based on pay-per-use system, making it a cost-efficient cloud solution.
- PaaS: Platform-as-a-service is all about cloud computing platform that allows developers to use it for managing their IT applications with fully control of the configuration settings like OS, database, web services, programming language etc., to host applications.
- IaaS: Infrastructure-as-a-service is related to offering virtualized computing resources on web. In IaaS model, the cloud provider will manage and host the infrastructure, including storage, hardware etc. on behalf of the users. Choosing the right cloud technology decides your enterprise's business operations. Whether to go for (Private cloud hosting or public cloud hosting or hybrid cloud hosting) entirely depends upon your scale of operations, IT budget, security needs and other such IT infrastructure and resource factors.
