Let’s understand the concept of cloud storage.

Cloud storage is a model that stores, manages, and backs up data on remote servers via the Internet.

It allows you to search for or store user data in a browser or dedicated application without having to access a physical storage device. One of the technologies that makes this possible is virtualization. Virtualization divides one physical resource into multiple virtual resources, allowing multiple users to share and utilize these resources concurrently. This makes it easier to manage data and increases the flexibility of storage utilization.

To put it simply, cloud storage is a system that facilitates data storage on the Internet. Cloud storage is also used for storing files on cloud drives, allowing companies to store large volumes of data or developers to store application data. Cloud storage offers more features than simple cloud drives. It provides many options, including various types of data processing (e.g., database, machine learning model, and more), APIs for programmatic data access and manipulation, access control, and redundancy settings.

Let’s find out the types of cloud storage.

What is block storage?

Block storage is storage for large-scale data processing and DB workloads and stores data in fixed-size blocks of pre-determined arrays. It is a high-availability storage service directly assigned to servers and is suitable for application environments that require large-scale data storage, such as database and mail servers. High-performance storage is available depending on the required level of performance. A backup policy with redundancy and failure recovery system enables reliable service without any data loss.

What is file storage?

In file storage, multiple clients share files over a network. It is file-level storage that provides data access to various clients over the network. Servers connected to a file storage volume can easily store and share data, making it convenient to utilize data on applications that use multiple servers. The service is available on a range of diverse applications from web content management and storage for entertainment data processing to container storage and big data analysis.

What is object storage?

Object storage is a service that provides large-capacity data storage space in cloud environments and allows users to store and use data on the Internet. The URL-based easy access to storage provides convenient data management. AES-256 encryption algorithm is used for secure data storage and downloads. The saved data is protected by various steps of security measures.

What are the advantages of cloud storage?

High reliability for data storage

Data replication is one of the key factors that improve the reliability of data storage. Cloud storage prevents data loss by replicating the same data on different servers, even in the event of a failure in a server.

Fast processing speed and high accessibility

Cloud storage is accessible anywhere via the Internet and guarantees flexible and fast data processing. It also provides easy data access, transcending physical distance.

High scalability

Cloud storage allows for easy scalability to meet user demands, expanding the storage capacity with ease. This provides significant benefits in responding to unpredictable data growth.

What are the differences between traditional server storage and cloud storage?

The key differences between cloud storage and traditional server storage are the storage location and method.

While traditional server storage directly stores data on servers or hardware, cloud storage keeps data on a distributed server network that can be accessed via the Internet. This is one of the main factors that guarantee the high reliability of cloud storage.

What should we consider when introducing cloud storage?

Sufficient preparation for data migration

Since folder structure or file format may be altered while transferring data between cloud services, it is required to check and prepare the folder structure and file format beforehand. Furthermore, data version management and backup policies must be set up.


Since cloud storage involves storing and sharing data over the Internet, users can be exposed to security threats, such as hacking and data leaks. Therefore, security measures such as data encryption, authentication, and access control are crucial.


The pay-as-you-go model is the general payment method for cloud services. Thus, it is important to understand and manage the usage capacity and pricing structure.
