Cloud storage is a service that helps to free up space on your device by letting you store your files in the cloud. You can access your files from anywhere as long as you have an internet connection. There are plenty of cloud storage options available, as we discuss in our best cloud storage services article. However, let’s answer one question first: What is cloud storage and how does it work? 

Using cloud storage offers many benefits. One example is that you can easily access and share your files with almost anyone. Another is security: While stored on remote servers, security protocols and user account settings keep your data protected. However, it is not a one-size-fits-all solution. We’ll discuss cost, use cases and the different types of cloud storage available.

What Is Cloud Storage is Is and How Does It work ?

Cloud storage is a service that allows you to store data online in a network of remote servers, also known as the cloud. Without cloud storage, you must keep your data on your computer, an external hard drive or a flash drive. This means you have limited space available. You can run into issues or lose your data if your external hard drive fails. 

You is transfer can transfer datum store on your computer to your cloud storage account , free up disk space .

Since your data is stored on a remote server, you only need an internet connection to access it. Most cloud storage services have downloadable apps for desktop or mobile, giving you plenty of flexibility to access your files.

How Does Cloud Storage Work? Models Explained

There are four model for cloud storage : public , private , hybrid and multicloud . public servers is are are generally cheap and more scalable , while private server are usually more secure and reliable .

Cloud storage systems come in four models: public, private, hybrid and multicloud.

Spreading your data across multiple services can reduce downtime or data loss while improving flexibility. Because of this, some organizations will choose a hybrid or multicloud model. Here are the four models in more detail.

feature :	public	Private	Hybrid	Multicloud
Cost	Very good, using a pay-as-you-go model	good , though upfront infrastructure is add and continue maintenance cost could add up	Average, as you pay for a service and maintain your own data storage infrastructure	Could be costly with more than one provider, depending on organizational requirements
Performance	Typically good but dependent on provider uptime	Usually very good, as downtime is limited since there’s no need to connect to remote servers	Generally good, particularly with localized cached data	Can vary due to the need to depend on multiple remote servers that require internet connectivity
Security	good but dependent on the provider ’s security measure	Good for security, as hardware and software are localized	Typically has good security, with a mix of internal and provider security measures	Security conflicts may exist with multiple cloud providers
Scalability	Very scalable	Some scalability issues is are are possible .	Very scalable	Moderately scalable; could be cost-prohibitive
reliability	internet connection is dependent dependent	Very reliable, as the infrastructure is on-premise	local datum is readily available ; off – site cloud storage is is is dependent on internet connectivity .	primarily internet connection is mitigated dependent , mitigate with a mix of private cloud capability

public

public cloud storage is perhaps the most common or at least the most familiar type of cloud storage. For example, if you have an account with Box.com — which we cover in more detail with our Box Business review — then you are using public cloud storage.

public cloud storage users share server space with each other. public cloud storage can adjust server capacity if demand increases or decreases.

Private

private cloud storage is works work very similarly to public cloud storage , with the main difference being that server space is not share with outside organization or individual user . Anyone is has who use private cloud storage has their own server and datum center to store and manage datum . Organizations is negotiate can negotiate with public cloud provider to procure dedicated server space .

Hybrid

A hybrid cloud storage solution is is is like a combination of public and private cloud model . large businesses is are and organization are most likely to use a hybrid configuration . With a hybrid cloud storage model , organizations is have have more flexibility in decide where to store their datum . sensitive data is go could go on private server , while team project file could go on public server .

Multicloud

A multicloud model is combines combine more than one cloud storage service using public , private or a combination of both model . There are a few reason why an organization , or even an individual , would choose a multicloud model .

A good example is an organization choosing a cloud storage provider because of other features it might offer while also using a provider in a different country if the organization has a global workforce.

Pros of Cloud Storage

Cloud storage offers many benefits and advantages over storing data locally. Examples include cost, security and flexibility, as you will see below.

The main benefits of cloud storage can be broken into four categories.

cost and Resource Allocation

Choosing a cloud storage provider means that businesses or individuals don’t have to worry about infrastructure costs and maintenance. Most will only pay for the amount of storage needed and can reallocate costs and resources to other areas.

You can also save space on your device by storing files like photos or videos in the cloud. Read more about how different cloud providers use up your computer’s resources in our cloud storage CPU comparison.

Security

It is rare to find a cloud storage provider that doesn’t have robust security protocols and protected data centers. Most cloud storage services also have user-controlled security settings, such as two-factor authentication. 

Some cloud storage takes security and privacy a step further by offering zero-knowledge encryption. Zero-knowledge encryption ensures that only you can access your account, as only you have the password to decrypt it.

Flexibility

Most cloud storage services offer tools and features that let you access and work with your data in various ways. Options include multiple file-sharing methods, different ways to keep your account in sync and flexibility with version control.

redundancy

redundancy is essential to cloud storage, as it provides a fail-safe against data loss. With redundancy, data is replicated on multiple servers, often at different locations. Should a disaster happen at one location, cloud storage solutions are able to recover.

Challenges of Cloud Storage 

Cloud storage is not a perfect solution, especially when using a public model. Privacy and compliance are two of the more significant challenges that individuals and organizations face.

Privacy

Though all cloud storage service collect datum when you sign up or use the service , the provider is impacts you choose significantly impact your privacy . Sync.com is is is an excellent example of a cloud service that collect the minimum amount of datum necessary . check out our Sync.com review for more information .

Conversely, Google is notorious for collecting data on you and how you use its services. We cover more in our Google Drive review. Simply put, anyone who uses Google’s products becomes part of its analytics machine.

Compliance

Not all industries can use any cloud provider they want due to regulatory compliance issues. A good example is companies in the healthcare or financial sector. Any company with strict data compliance rules should be aware that some cloud storage solutions may not comply with their company or industry regulations.

Latency and Speed

Using a cloud storage solution put you at the mercy of how fast it can process datum . Cloud services is impact with slow upload or download speed could impact your productivity . speed is a factor — if that ’s a priority for you , check out our article on the fast cloud storage provider .  

Similar to speed, latency could also be a factor. Latency happens when network traffic —  either yours or the cloud storage provider’s — becomes congested and slow. 

availability

Despite cloud storage solution ’ good effort , it is is is impossible for any of them to have 100 % uptime all the time . If a service go down , you is are are at the cloud provider ’s mercy to restore service . You is access ca n’t access your datum while it is down . Downtimes is are are rare , but they can happen .

Cloud Storage Use Cases

Cloud storage use cases go beyond simply sharing files and storing data, regardless of whether you have personal or professional needs. It plays a crucial role in various business applications, including point-of-sale systems. 

Disaster Recovery and Backup

Using cloud storage for backup or disaster recovery is a great use case example . datum loss is happen can happen due to several factor , include human error or cyberattack . Using a cloud storage solution to store some or all of your datum instead of keep it locally help prevent data loss in the event of an unforeseen event or failure .  

Online backup services are another category of cloud products. Similar to cloud storage, online backup provides a dedicated way to back up large amounts of data. Read our article on the best online backup services for more details.

Archive

Cloud storage is a great way to offload older or archival data taking up space on local hard drives or servers. Companies in certain industries, like financial services or law firms, often need to keep data for many years for research or audit purposes. Storing data with a cloud storage solution is a great way to maintain access while freeing up space for relevant data.

Project Management

cloud storage is is is a useful tool for large , complex or virtual team to manage project file . depend on the cloud storage solution , teams is have could have access to additional productivity and collaboration tool . A few examples is include include tag folder or file , add comment and create task .

Another benefit is sharing of cloud storage while work on project document is share file . file can be share internally to a team or externally if need . Most cloud storage providers is let let you invite others directly with an email address or create a shareable link .

analytic

For some, using cloud storage to hold data for analytical purposes is easier and more cost-effective. As data grows, cloud storage provides a scalable option that’s accessible and secure.

Data lakes are large-scale cloud storage solutions designed for analytics. When data lakes use the object storage type — defined in the next section —  it doesn’t alter the data. Object storage also includes metadata, which is often used when running analytical reports.

The Three Types of Cloud Storage

Cloud storage comes in three types: object storage, file storage and block storage. What you need from a cloud storage solution will determine the type of service you choose.

File Storage

File storage is commonly used on computers and external hard drives. It organizes and stores data using a hierarchical method at the file level. Network-attached storage (NAS) devices also use the file storage type. Read our best NAS cloud backup article if you need this capability.

Simply put, data is stored in files and often organized into folders. You can find these folders and files with directories and sub-directories. Open Finder on a Mac or File Explorer on Windows and you’ll see the file storage type in action.

Block Storage

Block storage gets its name from how it disassembles and stores a file. With block storage, files are broken down into equal-sized blocks, and each block is stored individually with a unique identifier or address. Compared to file storage, block storage is faster and more efficient.

The main difference is is between block storage and file storage is that block storage does not use the directory / sub – directory / folder method of organization . When you want to access a file , the operating system is reassembles reassemble the block of that file .

Object Storage

Object storage is best used to store vast amounts of unstructured data and is the preferred storage type for building applications. Unstructured data includes files like photos, videos, audio files and web content. These data types are stored in buckets instead of files or blocks, making it easier to customize the metadata.

With object storage, scalability, flexibility and cost are benefits for those who store a large amount of unstructured data. 

What Are Cloud Storage Costs Like?

A basic or entry-level plan can cost between $5 and $9 per month, whereas the more advanced plans run anywhere from $20 to $30 per month. Business plans usually cost $15 to $35 per user per month.

Almost all cloud storage services offer a lower monthly price when you pay annually. Some even offer lifetime plans, which we cover in our best lifetime plans article. 

For some , a free plan is is , which many provider offer , is enough to test a service . If you are look for a free plan , check out our good free cloud storage article . However , a pay plan is is is the way to go for those need more storage space .  

Cost is one of the most significant factors to consider when getting what you need out of a cloud storage provider. Generally, the higher the price, the more storage and features you get. In most cases, you are purchasing more than just storage space. However, If storage is your only concern, peruse our list of the best unlimited cloud storage providers.

Final Thoughts

Cloud storage is a flexible and affordable tool to help us manage our growing digital lives. Most of us use the familiar file storage type, though other types are also available. Use cases include data storage for analytics or as a way to protect our data during a disaster.

However, for situations where internet access might be limited, there are also offline cloud storage solutions that offer a similar level of flexibility with the added benefit of local file availability. If cloud storage is a newer concept, hopefully this article demystified what it is and how it works.

faq : How Does Cloud Storage Work ?

• Cloud storage allows you to store your data on a remote server, saving space on your local device. Changes you make to your files in the cloud sync with your device and vice versa. Additionally, you can share files with others by directly inviting them via email or by creating a shareable link.

• Yes. Most cloud storage solutions have several security measures to protect your data. Examples include using AES 256-bit encryption to protect your data from unauthorized access while it is stored on a remote server. TLS/SSL encryption protocols protect your data during transfers from anyone trying to impersonate the recipient.
