What is cloud storage


Nowadays, there are several types of storage, among which cloud storage is considered to be the newest. It allows you to store information and applications in the cloud, which makes them available in a remote location. Of course, only the owners of the files can access them. This often requires a password and login for the service. Cloud storage services are offered by providers that deal with the issue of security, server maintenance, related infrastructure, and guarantee constant access to customers' information.

The information uploaded to the cloud storage is hosted on the servers of the provider. Today, there is a huge choice among organizations that offer cloud storage services of any size at affordable prices. This opens up the opportunity for the average everyday person to do away with solid-state drives altogether.

This type of storage is somewhat similar to local storage networks in that servers are also used. However, there are a number of differences, such as information being sent directly to remote servers. Providers are constantly creating new virtual servers as the needs of their customers increase. This is why each person can only pay for the amount of storage space they use.

Types of Cloud Storage

In 2023, cloud storage will be provided in public, hybrid and private clouds.

Private cloud storage

By and large, private cloud storage is analogous to public cloud storage. However, private storage resides directly on the client's network and uses a physical server to generate virtual servers to expand the total storage capacity.

Public cloud storage

The most common type of cloud storage, allowing you to get your information anywhere from any device. You will need the Internet, password and login from your account page.

Hybrid cloud storage

A convenient cloud storage model is a mixture of private and public storage. In this way, organizations can distribute data across clouds, for example, private storage is suitable for sensitive information, while less sensitive information can be stored in public cloud storage.

What are the types of storage?

Each cloud storage has slight differences depending on the provider. However, more globally, all cloud storage is divided into 3 types, namely:

  • File-based;
  • Block-based;
  • Object-based.

Object storage

This type of storage treats information as an object. Thus all data includes metadata and an identifier. Repository storage replaces file distribution and folder hierarchies. They offer organizations limitless scalability.

File Storage

The most popular storage method that distributes all information in a hierarchical system of folders and files. This makes data retrieval an intuitive and fast process. This type of storage is often used for home directories, development platforms, and repositories for files, audio, and video.

Block storage

A type of storing large amounts of information in separate blocks. Each of them is a hard disk drive. This type of storage is often used by cloud storage providers to distribute large amounts of information between storage nodes. This allows for high connectivity performance and low latency, which is especially important for large databases and software.

What are the cloud storage requirements to consider?

While an open network user has almost no requirements for cloud storage, large organizations need to analyze the services as much as possible, as the wrong choice can result in huge losses. We have gathered the most important factors that should be used to select a cloud storage provider.

Reliability and availability

With quality cloud storage, you can significantly reduce the time spent on the normal processes found in data centers to ensure information availability and reliability.


When choosing a cloud storage service, it is important to make sure that your information is encrypted during storage and transmission. At the same time, data permissions and access control in the cloud should function in the same way as on-premises storage.

What are the use cases for cloud storage?

In addition to storing personal information, cloud services are incredibly useful in other ways as well. These days, many large companies are deploying applications, working with information, and stabilizing their own enterprise. Let's discuss some of the most private cloud storage use cases.

Analytics and data lakes

Analytics involves huge amounts of data, and storing it on the usual local SSDs can require a large financial investment. Cloud storage allows you to purchase exactly as much space as you need to store your data.

Backup and Disaster Recovery

The unlimited scalability and low price of cloud storage solves the problem in backing up and restoring information. This advantage is especially important for enterprises that constantly generate huge amounts of unstructured information.

Software Testing and Development

Testing and building applications inside the cloud reduces the time and cost wastage to a minimum. These days, the largest organizations use this method as it allows them to cope with the tasks at short notice.

Transferring data to the cloud

Abandoning SSDs altogether in favor of cloud storage seems like a great solution, as the second option stands out for its low cost, availability, and sustainability.


Cloud service providers, often using a public liability model, enable organizations to productively and cost-effectively control risk in the IT environment and provide effective risk management by ensuring compliance through proven, widely accepted platforms and programs.

Cloud Optimized Application Storage

Serverless and containerized technologies used by cloud-optimized software can fully meet customer expectations. These applications are several components that are independent of each other and are called microservices.


The exponential growth in the amount of information is becoming a significant challenge for many organizations. Regulatory requirements require long-term and secure storage of information. Cloud storage is the best solution for this.

Hybrid cloud storage

This type of storage allows you to open local applications and systems in cloud storage. In this way, you can eliminate local storage, saving costs, optimizing the control process and accessing the latest information utilities.

Database storage

Transactional databases work well with block storage, which has high performance and is ready to update information. With block storage, organizations can easily generate scalable, highly efficient and reliable transactional databases.

Machine Learning and IoT

Get advanced analytics and apply artificial intelligence with cloud storage.

Benefits and Challenges of Cloud Storage Adoption

Cloud storage is gaining tremendous popularity and displacing other types of information storage. Only in 2015, 30% of corporate data was in the cloud, by 2020 this figure increased by 20%. The whole point is that cloud storage is significantly superior to local storage systems.

Benefits of cloud storage

The list of cloud strengths includes ease of access and flexibility, support for remote monitoring, efficient scalability, and redundancy for backup migration.

Challenges of cloud storage

Despite continuous improvements, cloud storage has a number of weaknesses, such as the risk of provider lock-in, security challenges with large numbers of users, risk of downtime and outages, and fragmentation of the IT landscape. Otherwise, cloud storage is far superior to all other types of storage.
