Cost Estimates
Like to keep the bean counters happy?
Surely you've dealt with other professional services organizations where you were given hourly or daily rates – and really had no way of knowing how much consultancy you needed, so you had no idea of the cost, either.
We're different. Check out our Professional Service cost estimates for a clear picture.
Our cost estimates give you a good and clear idea of the amount of effort involved in deploying a standard cluster configuration for a number of use cases.
Take a look if you're planning to deploy
- 2-node MySQL High Availability with DRBD
- Multiple-node virtualization with libvirt and KVM
- 2-node highly available iSCSI storage
- 3-node Disaster Recovery (DR) with DRBD
- InfiniBand-based High Performance High Availability (HPHA) Storage
- 2-node DRBD/OCFS2 file system cluster
Please note: while we have compiled these estimates using our multi-year experience deploying clusters, individual configurations, and effort involved may vary. However, we'll be happy to issue a fixed-bid Statement of Work based on your individual situation. Please contact us for details.
