How Data is Stored in the Cloud?

Cloud storage means keeping your digital data on remote servers managed by a third-party provider instead of your own computer or company servers. This setup makes your information secure, well-managed, and always accessible through the internet. Businesses benefit because they don’t need to spend heavily on building or maintaining data centers, turning large upfront costs into smaller, ongoing expenses. Cloud storage is also highly flexible and scalable ,you can increase or reduce storage space anytime as your needs change. In this article, you will understand how data is stored in the cloud and why it is a smart, cost-effective solution.

How Your Data Travels to the Cloud?

Data is Stored in Different Steps:

• You upload your data (like files, photos, videos, or business documents) through an internet connection to these remote servers.

• Your data isn’t stored directly on one big machine. Instead, it’s saved on a “virtual machine” which runs on a physical server.

• To make sure your data is always available and to protect it from being lost, cloud providers often copy your data and spread it across many virtual machines in different data centers around the world. This is called redundancy.

• If you need more storage, the cloud provider can quickly create more virtual machines to handle the extra data.

• You can access your stored data from anywhere with an internet connection, using tools like web browsers, mobile apps, or other software.

Different Ways Cloud Data is Stored

Cloud storage comes in various forms, known as models and types:

• Public Cloud Storage: Your data is stored in shared data centers used by many companies. It’s like renting space in a big storage pool, you pay only for what you use and can access it anytime from any device.

• Private Cloud Storage: The servers and data centers are used only by one organization. Either the company owns them, or a provider gives dedicated servers. It’s chosen by businesses that need strict security and full control over their data.

• Hybrid Cloud Storage: A mix of public and private storage. Sensitive data stays in the private cloud, while less sensitive data goes in the public cloud ,giving both safety and flexibility.

• Multicloud Storage: Uses cloud services from different providers. Companies do this to use special apps, follow data rules in certain countries, or add flexibility and extra backup options.

Ensuring Data Safety and Availability

Cloud providers use different methods to keep your data safe and always accessible.

Data Replication

Multiple copies of your data are stored in different servers or locations. If one server fails, another copy is used so you don’t lose access. This makes data reliable but can increase costs. Sometimes systems use eventual consistency, meaning all copies may take a little time to fully update but will eventually match.

Data Lifecycle Management ( DLM)

Data goes through different stages like : creation, active use, storage, archiving, and deletion. DLM helps manage this process efficiently, cut costs, and meet compliance rules. Tools like Nutanix Data Lens can automate it.

Security Measures

Cloud providers use strong security such as locked data centers and advanced software protections. Important practices include:

• Shared responsibility model: The provider handles some security tasks, but users must also protect their own data.

• Data visibility: Keep track of all data to avoid hidden or “dark data.”

• Zero Trust approach: No one is trusted automatically ,every user, device, and app must be verified.

• Immutable storage: Prevents changes or deletion for a set time.
