Ceph is an Open Source Distributed storage solution and it puts together to simplify the highly scalable object, file-based storage and block under one whole system. Ceph supports both scale-up and scale-out using economical commodity hardware. Clusters of Ceph are constructed with the help of an algorithm called CRUSH (Controlled Replication Under Scalable Hashing) in order to run commodity hardware. Architecture Ceph is based on RADOS (Reliable Autonomic Distributed Object Store) and it provides multiple storage interfaces in a single unified storage cluster. Why Ceph?

How Cloud Computing Works At its core, cloud computing relies on a network of remote servers hosted on the internet to store, manage, and process data. Users connect via: The provider manages: This …
A Network File System is a distributed file system protocol that supports remote hosts to mount file systems through the network and interact with the file systems as though they are mounted sectionally. This allows us to connect resources to centralized servers on the network. Amazon EFS-Elastic File System gives you a simple, scalable, and fully managed elastic NFS file system to use with AWS Cloud services and on-premises resources. In this demonstration, we will show you how to configure a Network File System-NFS using AWS EFS and connect to …

Using LVM we can have multiple virtual partitions on a physical volume or a single virtual partition over numerous physical volumes. 1. Deploy an EC2 instance Login to your AWS management console and search for EC2. On the EC2 dashboard, click Launch Instance to deploy a virtual machine. Provide an instance name and choose the OS image, key pair, …
If user disk space usage is reflected incorrectly or not updating in cPanel, there is a way to force refresh the disk quota of cPanel directly from cPanel dashboard. We will be able to remedy this by refreshing the cPanel cache for this user.
