How is Data Stored in the Cloud?

Businesses are increasingly opting to store their data in the cloud since they need more elasticity, scalability, multi-tenancy, and better ways to manage their storage costs. Many users increasingly find it hard to manage the growing enterprise and cloud data in their on-premises facilities. To discover why the cloud’s popularity is on the increase, let us consider how data is stored in the cloud.

Cloud Storage Basics

Various types of cloud storage systems have a specific focus. Some store digital images and others store e-mail messages. Other systems store all types of digital data. Cloud storage systems have at least a data server that is connected to the internet. A computer user who is subscribed to any cloud storage service can send files to the data server, where the information is stored. If you want to retrieve the information you sent, you can access that server via a Web-based interface. You can access and modify the files or download them. In real life, cloud storage systems depend on hundreds of servers to offer the required security. Computers can require maintenance or repair at any time. By storing the data on multiple machines, the cloud mitigates the risk of loss of data.

Cloud Storage Reliability and Security

Many clients are not likely to trust a second party with their data if they have no guarantee that they can access it at will, and no other party can get at it. Cloud storage systems use the following techniques to secure your data and prevent risks:

Encryption

Cloud storage systems use symmetric keys to encrypt files. This means only an identical key can open the data you sent to the server. Even though encrypted information can be hacked, most hackers lack the required computing power to decrypt the information. In other words, once you send your data to the data server, you make it incredibly difficult for any other person to access it.

Authentication processes

The authentication process also increases the reliability and security of cloud storage systems. Before you use the service, you must create a unique username and password, which means anyone who does not have your logins has no access to the data in the cloud.

Authorization practices

Enterprises and individuals have an option to provide a list of people who have the right to access the stored information. Corporations have several authorization levels. For example, front-line employees may have limited access to the system. But managers can have a higher level of authorization and access lots of files. Due to these authorization measures, organizations can use the cloud to work closely with their remote teams.

Conclusion

Even with these security measures, some business owners are still concerned that their stored data is vulnerable. As we have discussed, depending on your choice of a cloud service provider, hackers may access some sensitive files and manipulate them. At the same time, an unstable storage system can be a liability to an organization. That is why it is proper to choose a storage service with multiple data servers. While there are several secure and reliable cloud storage services, it is acceptable for a business to consider having an offline backup.
