Cloud computing have advantages and disadvantages.

Cloud advantages:

There are 3 types of cloud services:

1. Storage only cloud services: it allows users only to save your data on the cloud and to back up, example; Google drive, drop box and I cloud
2. SAAS (software as a service): it offers software that runs on the cloud that can be accessed for free or based on a subscription fee, example; Google docs, sheets and slides.
3. PAAS (platform as a service):  it allows users to create SAAS application and it provides web-site building platforms, example; I page, Engine Yard.

In this seminar, also Dr. Ousama Hatoum talked about the PANDA Cloud Antivirus which is a cloud antivirus, run on the cloud and it is faster and lighter than traditional antiviruses. He explained also the 2 step verification it is for more security. To overcome the disadvantages of cloud that the administrator can read our data and deleted, so the 2 step verification when we downloaded it we have 2 passwords rather than one password so in this case the administrator can’t see our data.
