An online space that is used to store your data such as
- other structured/semi-structured/unstructured data,
and can be accessed by any device is known as cloud storage.
How Cloud Storage Works
- Upload the data from your device into the cloud of your choice.
- The uploaded data reaches a master control data server located in a data center owned by your cloud service provider. The master server maintains a copy of your data in various storage servers.
- You can retrieve the data using APIs or web-based protocols.
Cloud Storage Security
Cloud storage providers enable security of the data by adopting various methods:
- Encryption: A complex algorithm is used to encode your data, users will need the encryption key to decode the data.
- Authentication: Protects access to data by enforcing users to create username and password. Multiple levels of authorization such as multi-factor authentication will be used as appropriate.
Cloud Storage Benefits
- A reliable and secure system to back up your essential files.
- Files stored in the cloud can be retrieved remotely.
- Files are accessible from anywhere.
- An affordable way of protecting important data.
- An assurance of restoration of data from any unwanted failure or data loss.
- No need to install storage equipment.
- Offers enough mobility in the workflow of a business or company.
Cloud Storage Risks
Irrespective of the many benefits, cloud storage, comes with a few notable risks as well:
- Data security (data is vulnerable when it is transferred to and from the cloud).
- Accessibility depends on network connectivity.
- Cost depends on the usage.
Cloud application programming interface serves as a layer between users, cloud services, and resources.
It interacts with the cloud infrastructure to assist with
- Storage and
- Network resources for requested cloud applications or services.
Cloud APIs vary according to the provided services, as follows:
- Infrastructure as a Service (IaaS): Infrastructure APIs help in the provision of computing and storage resources.
- Software as a Service (SaaS): SaaS APIs enable connectivity and interaction with the application layer.
Platform as a Service (PaaS): PaaS APIs provide back-end architecture, functionality for the applications.
