Creating Your Own Private Cloud with Proxmox Virtualization Cluster and Ceph for Distributed Storage

In today’s digital landscape, businesses are increasingly seeking ways to optimize their IT infrastructure. One approach gaining traction is the creation of a private cloud using Proxmox as the virtualization platform and Ceph for distributed storage. This combination offers enhanced data security, cost efficiency, scalability, and flexibility.

Benefits of a Private Cloud

The private cloud model allows businesses to maintain full control over their IT infrastructure while leveraging modern technologies like virtualization and distributed storage systems.

Enhanced Data Security

By maintaining your data within your own infrastructure, you reduce the risk associated with third-party storage solutions. Proxmox’s virtualization layer adds another layer of security, ensuring that each VM operates in an isolated environment.

Cost Efficiency

While initial setup requires investment in hardware and expertise, operating a private cloud can be more cost-effective in the long run. You avoid the ongoing expenses of public cloud services, such as hourly rates for VMs, and instead incur one-time costs for infrastructure.

Improved Performance

Proxmox’s efficient resource management and Ceph’s fast storage solutions ensure that your applications perform optimally. This is particularly beneficial for latency-sensitive operations.

Scalability and Flexibility

The ability to add nodes as needed allows you to scale resources up or down based on demand, ensuring that your infrastructure remains responsive to business needs without over-provisioning.

Redundancy and Reliability

Ceph’s distributed nature ensures data availability even in the event of hardware failures. Proxmox’s clustering capabilities further enhance reliability by allowing for seamless virtual machine failover between nodes.

Control and Customization

With a private cloud, you have full control over your infrastructure. This allows for tailored configurations that meet specific business requirements, from custom security protocols to optimized resource allocation.

Hypothetical Costs for a Basic Cluster

To illustrate the cost implications of setting up a private cloud using Proxmox and Ceph, consider the following hypothetical scenario:

  1. Hardware: Three servers with 32GB RAM, 8-core CPU, and 2TB SSD(x3) storage each.
  2. Networking: 10Gbps switch and cabling.
  3. Node Specifics: Each node should have (2x) 10Gbps NICs for Ceph replication and VM traffic.
  4. Software: Proxmox VE and Ceph.

The total cost of this setup would depend on factors such as hardware brand, software licensing, and professional services for setup and configuration. However, this basic cluster can serve as a starting point for estimating costs.

Let’s say we’re a small business that needs to host some Windows VMs (Active Directory, SMB File Server, MSSQL Server and Reporting, and a HA failover for each), a firewall VM, and maybe a utility Docker Linux VM host for Grafana/Prometheus monitoring.

For node hardware, I’d go with a Minisforum MS-01 with 32GB of RAM and 2x 10Gbps NICs. These run around $850 at the time of writing with no SSDs included. Since these can have up to three M.2 NVMe drives, I’d go with three 2TB NVMe drives for around $200 each. The 10Gbps switch would be around $500, and the cabling would be around $100. The software would be free, as Proxmox and Ceph are open-source.

That brings the total cost to approximately $1,550 per node or $4,650 for the cluster. This is a very cost-effective solution for a small business that needs a private cloud.

This cluster could easily run (x6) 4c/8GB RAM VMs with 500GB of storage each, and still have room for growth. What would the cost to run that many VMs with the same specs per month on Azure? A one year savings plan for an A4 v2 VM is $94.27 per month. That would be $565.62 per month for six VMs, or $6,787.44 per year. This is a savings of $2,137.44 in the first year alone! That is only for the compute on the cloud, and does not include all the storage, networking, etc. extras that come along with a cloud provider.

Conclusion

Creating your own private cloud using Proxmox and Ceph offers numerous benefits, from enhanced security and cost efficiency to improved performance and scalability. By leveraging these technologies, businesses can tailor their infrastructure to meet specific requirements while maintaining full control over their data. While the initial setup may require investment, the long-term savings and flexibility make a private cloud an attractive option for many organizations.
