I need help to write 1 page about the disadvantage of cloud computing. Below is the information that I found on the Internet. You can write base on my information. Paraphrase is ok.

Main Disadvantages of Cloud computing

Downtime

Cloud computing systems are internet based, which means your access is fully dependent on your Internet connection. And, like any hardware, cloud platforms themselves can fail for any one of a thousand reasons.

the most reliable cloud computing service providers suffer server outages now and again.

Security and Privacy

cloud data is accessible from anywhere on the internet, meaning that if a data breach occurs via hacking, a disgruntled employee, or careless username/password security, business data can be compromised.

Although cloud service providers implement the best security standards and industry certifications, storing data and important files on external service providers always opens up risks. Using cloud-powered technologies means you need to provide your service provider with access to important business data. Meanwhile, being a public service opens up cloud service providers to security challenges on a routine basis. The ease in procuring and accessing cloud services can also give nefarious users the ability to scan, identify and exploit loopholes and vulnerabilities within a system.

Cost

Cloud applications (also known as Software as Service applications or Saas) do not require large investment for licenses or support infrastructure. Having to customize your cloud-based software to suit your needs can add greatly to the cost. If you use custom-developed in-house software, it may not be possible to move it to the cloud without an expensive rewrite – definitely a disadvantage.

Inflexibility

Be careful when you're choosing a cloud computing vendor that you're not going to become a "forever" customer because their applications and/or data formats do not allow easy transfer/conversion of information into other systems.Some vendors deliberately attempt to "lock-in" customers by using proprietary software/hardware, so that it is impossible or very expensive to switch to another cloud vendor.

Customer support

Most vendors have made great strides in improving technical support over the past few years, but better service comes at a price.Google's basic "Silver" support package for their cloud platform currently costs $150/month, which has four hour response time (during business hours only) and does not include phone support. Other cloud vendors such as Microsoft have similar support plan options.

If your business needs are such that you need a rapid response to customer support issues, make sure that your cloud services vendor has plenty of options available for technical support, including email, phone, live chat, knowledge bases, and user forums. Be prepared to pay for higher levels of support, particularly on evenings or weekends.
