There is no single answer to this question as PLM (Product Lifecycle Management) encompasses a wide range of software solutions and services that can be delivered via the cloud. In general, though, cloud PLM can be defined as a way of using PLM software and services that are hosted remotely and accessed via the internet, typically on a subscription basis.
Many organizations are moving towards cloud PLM for a number of reasons, including increased flexibility, lower upfront costs, and easier scalability. Cloud PLM can also make it easier to share data and collaborate with partners and suppliers, as well as providing anytime, anywhere access to product data.
