Disadvantages of PaaS Cloud Computing layer .
- Network connectivity dependency
- Vendor lock-in:
- Limited Control
This direct tie-up with the Internet means that a company needs to have reliable and consistent Internet service as well as a fast connection and bandwidth to reap the benefits of Cloud Computing.
Vendor lock-in is the biggest disadvantage of cloud computing. Organizations may face problems when transferring their services from one vendor to another. As different vendors provide different platforms, that can cause difficulty moving from one cloud to another.
cloud infrastructure is completely owned and managed by the service provider, so the cloud users have less control over the function .
