For beginners, it is quite difficult to pick the right type of cloud service. They need to understand the difference between public cloud storage, private cloud, and hybrid cloud to know what the best option is.

In this article, we will discuss different types of cloud storage and explain their features, characteristics, and limitations. We will also introduce various public cloud services to help you select the best cloud storage.


What are the Different Types of Cloud Storage?

Cloud storage is broadly classified into three types, depending on the availability to customers.

Public Cloud Storage

Public cloud storage is a type of storage where various users, organizations, and subscribers use the same servers, hardware, and other resources on a sharing basis. The resources are owned by a third party, and the storage services are offered to people according to their needs.

The public cloud is the most affordable option, and it is the right option for personal use. There is enough storage, and you can select the right plan according to your data. Their users do not need to do anything complex; they just need to choose and subscribe to the storage. The security, hardware, maintenance, and everything else are the responsibility of the service provider. Therefore, it is better for personal use, office use, and small businesses/organizations.

Private Cloud Storage

Private cloud storage is a dedicated cloud for an entity. For instance, if any organization buys it, it will be the only one using the hardware, servers, and other resources; there is no sharing. With that being said, the service can be customized as needed. The user has more control over the storage. The security is optimal, and there is nothing to worry about the privacy breaches and data leakage.

Private cloud storage is preferred by large organizations and businesses that need a storage infrastructure. Since the on-premises infrastructure costs a lot, it is better to use private cloud storage. It is better in performance, security, and everything, but all these things come at a cost. Private cloud storage is quite expensive compared to public cloud storage, and it is usually not the option for personal use.

Hybrid Cloud Storage

The last type of cloud storage is hybrid cloud storage, which is a combination of private cloud storage and public cloud storage. If an organization needs a private cloud, it does not mean that all of its data needs to be in there; it can also have a public cloud for some data. It is a more cost-effective option rather than going for a private cloud. Hybrid cloud has the features, benefits, and pros & cons of both types of storage.

Upsides and Downsides of Public Cloud

Now that you know which type of cloud storage to opt for, let’s dig deeper into the pros and cons of public cloud, which is the most suitable option for most users.


  • Cost: As has been discussed, the cost of the public cloud services is much lower than private and hybrid clouds. You can choose the best plan for your needs. There are plans for individuals, teams, and businesses, and the best part is that you can get custom plans as well. Due to sharing of resources, the cost is very low.
  • Ease of Use: Public cloud is quite easy to use. There is no experience or expertise required. Even if there is any installation or setup needed, it can be done without any hassle.
  • Scalability: Public cloud have a larger infrastructure because they handle a lot of customers. Users can scale the storage as much as they like. There is an option for unlimited scalability. The best thing is the storage can be scaled whenever you want.
  • Maintenance: There is almost no maintenance required. Everything is the responsibility of the service provider. Thus, public cloud can save you a lot of time and energy for everyday use.
  • Uptime: The uptime of the public cloud is ensured because there are many users. They cannot bear any outage; therefore, they usually have backup options to keep everything running. You get the best uptime in a public cloud.


  • Security: The security of a public cloud is not as good as a private cloud. Many users share the same resources, so the threats of hacking, viruses, malware, data leakage, and privacy breach are higher. If your data is too confidential, you must choose private cloud storage. For common users with a relatively low level of security need, it is still advisable to choose secure cloud services.
  • Control: You cannot control the public cloud. The service provider only offers the storage you need, and the rest is under their control.
  • Flexibility: Due to a lack of control, you cannot adjust or optimize the cloud according to your needs. So, there is almost no flexibility.
