Cloud storage has made it easier for us to store our data. Previously, you might have used devices like a USB storage drive or an external hard disk to keep your information safe. Do you still find them in daily use? Cloud storage replaced these devices – to an extent – as the internet became faster and cheaper.

Businesses used to have big server rooms and data centers instead of USB drives or external hard disks, but many have migrated to the cloud to reduce costs and gain more scalability.

Some businesses adopt a hybrid cloud solution, keeping sensitive data in their private servers and transporting the rest to the public cloud. It provides scalability and cost-effectiveness without compromising data regulation or violating on-premises infrastructure requirements.

In this article, we study the fundamentals of cloud storage and discover the best options for migrating to the cloud. 

It’s beneficial for a variety of reasons.

• Cost-savings: You don’t have to invest heavily upfront in storage hardware. You just pay for the space you use.
• Flexibility: The space grows and shrinks to accommodate storage requirements. 
• Availability: It lets you access data from anywhere anytime, as long as you have the internet. 
• Less hassle: You don’t have to worry about security or maintenance of the cloud storage space. The company that owns it takes care of that for you.

Simply put, you rent a place to store your digital stuff, and in return, you get easy access to your data anytime without spending a lot on in-house storage infrastructure.

How does cloud storage work?

Cloud storage sends data to servers hosted by cloud storage vendors. These servers are virtual machines (VM) hosted on a physical server. The cloud provider creates new virtual servers as your storage needs increase.

You can access the storage online. When you connect, the cloud provider forwards the data to a pool of servers in one or more data centers, depending on the provider’s size and capabilities. 

Storage happens on multiple machines to support redundancy, which is important for data availability. If a server goes down for maintenance or outage, this redundancy ensures your data is accessible. 

Usually, the providers offer storage in public, private, or hybrid clouds.

Types of cloud storage

Cloud storage has transformed how we store, access, and manage data. Below are the common types of cloud storage available to us on the market. 

File storage

File storage, also known as file-level or file-based storage, hierarchically organizes data. It stores data in files, places the files in folders, and organizes the folders within directories and subdirectories. To find a file, you only need to know its path. 

File storage works for structured data that’s easy to arrange. However, it requires more hardware for scaling and becomes slow when managing a lot of info.

Multiple users can access and share files stored in off-site data centers. You simply pay a monthly fee, making scaling capacity and managing data security easier and cheaper.

Block storage

Block storage, or block-level storage, divides data into blocks and stores them separately using unique identifiers. The blocks are placed across different systems. This method decouples data from user environments, and when users make a request, the data blocks are reassembled, facilitating quick retrieval. 

Object storage

Unstructured data is challenging to organize in traditional databases. It is consistently growing with increasing internet communication, social media, and smart devices. Object storage helps manage volumes of unstructured data. 

Object storage is a cost-effective solution for archiving and backing up large amounts of data. It adds more scalability than file or block storage, allowing you to manage terabytes and petabytes of information. 

Benefits of cloud storage

Cloud storage offers several benefits for businesses of all sizes. Let’s examine some notable advantages. 

• Off-site management: The cloud provider takes care of maintenance and data security. You don’t have to purchase any equipment.
• Quick set-up: You can quickly set up the cloud storage within a few hours or days.
• Easy to grow: Cloud storage always keeps you from running out of space. You can add more capacity whenever your storage needs increase. 
• Increased adaptability: If something bad happens, like a natural disaster, your business can continue to operate online since your data is stored in an offsite location. 
• Easier data management: You can add and remove storage, change the ways data is stored, and move less-used data to cheaper storage options. 
• Protected data: Cloud storage offers features like data versioning and replication so you can recover quickly from any mistake or failure. Plus, it stores data in secure data centers. 

Challenges of cloud storage

While cloud storage brings many benefits, it also faces some challenges that businesses must consider.

• Security: Although cloud storage providers maintain the latest security measures, hackers have managed to execute cyber attacks. Some users feel uncomfortable storing their sensitive data in the cloud. 

• Lack of control: When you move data to the cloud, you trust a third party to take care of it. Giving up control over your data can make some users uneasy. 

• Data transmission delays: If the internet is slow, sending data to the cloud takes time due to latency. Businesses can address this with a faster internet connection. 

• Regulatory compliance issues: Certain businesses, like those in healthcare or finance, must follow strict privacy and data storage laws. The law may limit the use of cloud storage in particular situations, such as when medical records are stored on the cloud. 

G2’s top 5 hybrid cloud storage solutions

Hybrid cloud storage solutions connect private and public clouds. They let companies benefit from the scalability and cost savings of the public cloud, as well as the security and control of private, on-site storage. You can store data using file, object, or block storage options.

To be included in our top five hybrid cloud storage solutions list, a product must: 

• Bring private and public storage environments together while consolidating storage infrastructure
• Let users access their data on public, on-premise, or private clouds

1. Google Cloud Storage

Google Cloud Storage stores unstructured data, like videos and documents. Organizations use it for data lakes, web hosting, or artificial intelligence (AI) data storage. It offers customers credits up to $300 to try out the software. 

What users like best:

“I have used several Google Cloud services like VM Instances, BigQuery, Looker Studio, Cloud Composer, Cloud Storage, etc. I loved the overall experience of using the GCP services. Setting up the whole cloud environment, giving roles and permissions, and using services is pretty smooth. And most of the services can be integrated with other software quite easily. 

You can use Airflow directly with Google Cloud Composer, which is excellent. I have been using GCP services daily for almost two years and love the overall Google Cloud environment.”

– Google Cloud Storage Review, Muskan C.

What users dislike:

“I integrated it for an e-commerce application using NodeJS. I feel the documentation could be improved. As compared to others like Amazon Web Services, Google Cloud Platform still has a small community, which seems to be a drawback.”
