In recent years, many site owners have migrated their websites from traditional hosting plans to Cloud Hosting services. There are many benefits offered by Cloud Hosting, including maximum uptime guarantee, instant scalability, faster speeds, top-notch security as well as higher reliability. Today, we are going to talk about a specific benefit of Cloud Hosting services – data redundancy and understand how these hosting services guarantee high redundancy levels for site data.

Cloud Hosting – Data Redundancy

Data redundancy means having multiple copies of the same data at different locations. In web hosting, this can play a crucial role in ensuring uninterrupted services and maximum uptime.

1. Storage architecture (Ceph)

Most Cloud Hosting providers use a storage architecture like Ceph that offers data redundancy to websites. Ceph automatically duplicates data across nodes, creating backups as per the desired frequency.

Ceph ensures that for each object, there is a primary Object Storage Device or OSD handling the primary operations for the client. Simultaneously, it creates secondary OSDs that are under the control of the primary OSD. The primary OSD ensures that each secondary OSD is ready to become primary at any time. Ceph also uses erasure coding to optimise storage density.

It runs on an algorithm called CRUSH or ‘Controlled Replication Under Scalable Hashing’ that allows it to replicate data without using any additional hardware. It also allows it to eliminate any single point of failure. The algorithm computes the data location in the cluster and communicates with the OSD directly. While by default, Ceph creates three replicas of the data, you can choose the number of replicas based on your need.

2. Data mirroring

Data mirroring, as the name suggests, is about copying data to another location. In Cloud Hosting, multiple servers work together to offer a reliable hosting platform to a website. It assures reliability by copying the site data across multiple servers in the network. It ensures that if the primary server fails, another server takes its place to ensure that the website does not experience any downtime. Mirroring also works as an additional safety net providing the latest working copy of the data in the event of a security breach.

In today’s times, a slow or down website can be detrimental to any business. While web hosting companies are trying to use the best hardware and infrastructure to ensure maximum uptime, having data redundancy can help ensure uninterrupted services in the event of an unexpected technical issue. With data mirroring and storage solutions like Ceph, web hosting companies ensure that Cloud Hosting services guarantee high data redundancies.

Summing Up

Cloud Hosting provides a range of benefits to websites. Data redundancy is one of the most important benefits as it ensures maximum uptime and widens the safety net offering protection in case of a security lapse. If you are running a website with critical applications and sensitive data, then you need a hosting service that offers data redundancy to ensure that your customers don’t find your site frequently unavailable. Ensure that you consider this aspect while choosing a web hosting plan. Good Luck!
