Question - Disadvantages of SaaS cloud computing layer
Answer -
1) Security
Data is stored in the cloud, so that that security may be an issue for some users. However, cloud computing is not more secure than in-house deployment.
2) Latency issue
Since data and applications are stored in the cloud at a variable distance from the end-user, there is a possibility that there may be more significant latency when interacting with the application compared to local deployment. Therefore, the SaaS model is not suitable for applications whose demand response time in milliseconds.
3) Total Dependency on the Internet
Without an internet connection, most SaaS applications are not usable.
4) Switching between SaaS vendors is difficult
Switching SaaS vendors involves the slow and challenging task of transferring the massive data files over the internet and then converting and importing them into another SaaS.
