IBM is preparing to go live with Power8 servers offered as part of the firm's SoftLayer infrastructure-as-a-service platform.
Availability is slated for some point in the second quarter of this year, and the platform will give customers new options for handling data-intensive workloads, IBM said.
Big Blue has been promising Power-based cloud services for at least a year, ever since acquiring SoftLayer and starting an aggressive expansion of its cloud business based around it, such as opening a new London data centre last summer.
The move chimes with IBM's push on the Power architecture, which it promotes as better suited for mission-critical enterprise workloads than commodity x86 servers.
The firm started the OpenPower Foundation in 2013 with a view to developing a partner ecosystem around the Power architecture. The group now boasts about 80 members.
The OpenPower-based bare metal servers will be available initially from SoftLayer's Texas cloud centre in Dallas, but IBM plans to expand to global availability in the future.
Once available, the new SoftLayer service will offer on-demand access to bare-metal OpenPower servers, aiming at businesses that want to operate demanding, data-intensive workloads in the cloud, typically running on Linux.
"Being the first cloud service provider to offer OpenPower-based bare metal servers strengthens our portfolio and makes it easy for users to take advantage of one of the industry's most powerful and open server architectures," said SoftLayer chief information officer Sonny Fulkerson.
"This offering allows SoftLayer to deliver a level of performance, predictability and dependability not always possible in virtualised cloud environments."
IBM worked closely with OpenPower Foundation members Tyan and Mellanox Technologies to bring the new cloud server offering to market.
Mellanox is a supplier of InfiniBand and Ethernet connectivity products, while Tyan was the first OpenPower partner to ship Power-based server systems last year.
Pricing and configurations for the OpenPower-based bare metal servers will be detailed at the time of availability, IBM said.
