Terraform embraces Arm: More choice, greater flexibility

In recent years, Arm architecture has grown in popularity due to its potential for cost savings, increasing performance, and sustainability. Consequently, companies are increasingly adopting Arm for their computing workloads. This shift led to customer demand for the ability to run Terraform Enterprise and HCP Terraform agents (tfc-agent) on Arm-based compute platforms, such as AWS Graviton servers.

While HCP Terraform has already supported Arm architecture, today, we're excited to announce that Terraform Enterprise and HCP Terraform agents now support Arm architecture. This provides customers with greater architecture choice and flexibility (Arm64 and x86-64), enabling them to maximize their IT investments, as Arm based processors are designed to deliver higher performance over lower power consumption for the same workload.

With this release, customers can choose between processor architecture options to optimize for cost and performance. One HCP Terraform customer reports, “we’ve moved our clusters to being 100% Graviton CPUs, and now we’re building our containers to be Arm only.” This customer can host their tfc-agents in those clusters. Terraform Enterprise customers can now host their Terraform Enterprise instances and self-hosted agents on Arm.

Here is an example savings dashboard for Amazon EC2 Graviton:
