Cloud Storage FAQ
These are some of the most often asked questions about cloud storage and cloud-based services.
What is the cloud?
The cloud refers to computers and hard drives operated by companies (or individuals, if it is a private/personal cloud), which provides the ability to store data on the aforementioned computers. The data is stored in a redundant manner, and is backed up continuously, making data loss highly unlikely.
Since the cloud is made up of computers, some cloud services provide not only storage options but also data processing and software as a service (SaaS).
Can I access my data from anywhere?
That is indeed the case. You can access your data from any device with an internet connection and browser (or appropriate app).
Is cloud storage secure?
In most cases any data sent to cloud storage providers is sent over a secure connection and is encrypted before it is stored.
Does cloud storage provide complete privacy?
In most cases it does not. Even though the data is sent over a secure connection and is stored in an encrypted form, most of the time the company providing the storage service has the decryption key for your data, and any employee with access to that information can decrypt your data, though this is unlikely.
On the other hand, there are companies which offer technology that ensure the encryption and decryption key is never revealed to their servers, and hence they are unable to decrypt your data since it gets encrypted locally (on your computer) before being sent over to their servers. This type of service is called zero-knowledge.
How much does cloud storage cost?
The cost of cloud storage varies based on the type of storage and encryption offered, and the amount of storage space required. Generally, the more space you rent the cheaper the per gigabyte cost.
