Build your own Cloud Storage with Ceph

Public clouds were created around the premise of dynamic demand, scaling up and down to the right size based on the resource demands of the application or organization. This flexibility is very appealing and justifiable when it comes to resource management around computing resources. However, when storing data in the cloud, more often than not you don’t only pay for storage but also to read (egress) and write (ingress) to the storage system. With public cloud storage, the egress and ingress costs can be unpredictable, which makes building your own cloud storage so appealing. Typically, an organizations storage usage will grow over time, both in capacity as well as in egress/ingress making the cost grow as well. While most public cloud providers do not charge for ingress, they do however charge for API calls. This pricing model can make for unpredictable and variable monthly costs, and make it difficult to budget for.

We look at Proxmox VE

Proxmox Virtual Environment is an open source server virtualization management solution based on QEMU/KVM and LXC. It is a Type 1 hypervisor, which means that it is installed directly on the bare metal or dedicated server. Users can manage virtual machines, containers, highly available clusters, storage and networks via an easy to use web interface, or through the command line.

The main difference between Type 1 and Type 2 hypervisors is that Type 2 hypervisors are hosted hypervisors, which means they are installed on an existing Operating System, where Type 1 hypervisors – as already mentioned – is installed directly on the hardware.

Examples of Type 1 Hypervisors include VMWare ESXi, Proxmox VE, KVM, Xen, Hyper-V (It converts Server 2012 into a Type 1 Hypervisor)

Examples of type 2 Hypervisors include Microsoft Virtual PC, Oracle Virtual Box, VMware Workstation, Oracle Solaris Zones, VMware Fusion, Oracle VM Server for x86 and more.
