Traditional IT operates on physical hardware and software which is owned and maintained by the company on-site. It’s an expensive approach at upfront and calls for ongoing maintenance. Also, scaling of resources with changing needs is quite difficult and time consuming. On the other side, Cloud computing refers to the IT infrastructure including servers, storage, databases, software and networking over the internet provided by a cloud provider. In this, businesses don’t have to invest on hardware and software, allowing greater scalability and flexibility of resources as needed.
