Oracle has announced it is offering Arm-based cloud computing, using processors from Ampere Computing.

Arm Holdings designs semiconductors and licenses those designs to other companies. The processors offer a combination of power and efficiency that make them ideally suited for use in compact spaces, making them the preferred chips for smartphones and tablets. Those same qualities also make them ideal for data center operations, where cooling and power requirements are at a premium.

Oracle now joins Amazon as one of the companies offering Arm-based cloud computing services, powered by Ampere A1 Compute chips. Oracle is touting its cost, a mere one cent per core hour, as the industry’s lowest cost per core.

“We see increasing demand for server-side Arm computing and adding Arm-based compute instances to our extensive portfolio of offerings enables customers to pick and choose the right processors for their workloads,” said Clay Magouyrk, executive vice president, Oracle Cloud Infrastructure. “Now customers who need an Arm platform for development can get the flexibility, scalability, and price-performance they need. We’re also making it really easy for developers to move their apps and develop new ones on Oracle Cloud Infrastructure.”

“Ampere instances on OCI is a breakthrough for developers. Oracle’s Free Tier is a great offering that allows them to test the OCI Ampere A1 compute platform and experience the first-cloud native processor that delivers predictable performance, scalability and power needed,” said Renee James, founder, chairman and CEO, Ampere Computing. “The Oracle Cloud has all the tools developers need to try new technology, get excited about new platforms and develop new applications.”

Arm semiconductor adoption in the data center is another increasingly worrying sign for Intel. While Arm has dominated the mobile market, Intel was the king of traditional computers and the data center. Last year, however, Apple announced it was switching its Mac platform to its own custom silicon, based on Arm designs. Microsoft has started following suit, pushing Windows on Arm.

With Amazon and Oracle both supporting Arm-based cloud computing, Intel’s last stronghold is now under full assault.
