Talkdesk’s reported path to OpenTofu was gradual coexistence, not a documented, completed switch away from Terraform. The Linux Foundation’s 2025 webinar description says the company manages both tools side by side, applies deployment guardrails, and partnered with Spacelift for centralized policy enforcement and automation. It reports more than 4,000 OpenTofu stacks in production, but does not explain how that count was measured or independently verify it.
What the Talkdesk case says
The Linux Foundation webinar, recorded March 25, 2025, featured Marcelo Almeida, Principal Platform Engineer, and Luis Almeida, VP Technology, at Talkdesk. James Humphries of Spacelift, identified as an OpenTofu core contributor, introduced the session. The event description presents Talkdesk’s reasons for adopting OpenTofu as including scalability and autonomy, while describing the broader move as a gradual embrace of open-source optionality.
The account is useful as an example of an enterprise operating Terraform and OpenTofu in parallel. It is not a detailed migration report: the public event descriptions do not specify a runbook, implementation timeline, cost or savings, reliability measures, or quantified comparison with Terraform-only operations.

According to the Linux Foundation’s event page, Talkdesk continued to manage Terraform and OpenTofu side by side while retaining familiar workflows. That is evidence for coexistence as the reported transition strategy, not proof that every repository, provider, module, or state file was interchangeable between the tools.
#1 Best Overall
For a platform team considering a similar path, the practical question is not simply whether two tools can be present. It is how to define the boundaries between them and preserve clear ownership of changes. The Talkdesk description does not say how its teams handled sequencing, version pinning, state conversion, or rollback, so these should be treated as design questions—not details of Talkdesk’s implementation.
What the reported scale figure does—and does not—show
4,000+ OpenTofu stacks in production — The Linux Foundation, 2025. This is the figure stated in the webinar description. The source does not define “stack,” provide a counting method, or give a more precise measurement date than the 2025 session context. It is a publisher-reported figure, not an independently audited metric, and it does not establish that any particular product or practice caused the reported scale.
Guardrails, policy, and automation
The event page says Talkdesk developed consistent deployment guardrails to standardize infrastructure management at scale. It also identifies Spacelift as a partner for centralized policy enforcement, automation, and management of both Terraform and OpenTofu environments. That describes the partner’s reported role in this case; it is not an independent evaluation or evidence that a particular platform is necessary for enterprise OpenTofu adoption.

The public description does not name the guardrails, policy rules, architecture, or controls used. Teams assessing their own operating model can use the case to frame questions such as:
Rank #3
- How will the same policies apply across Terraform and OpenTofu workflows?
- Who may approve and execute infrastructure changes, and how are those actions recorded?
- How will exceptions be reviewed without creating an ungoverned parallel path?
- How will automation handle differences in versions, providers, and workload ownership?
Questions to resolve before adopting a coexistence model
The webinar description frames migration concerns around “How seamless is the migration?”, “What about long-term support and stability?” and “How can I co-manage existing tools like Terraform?” It does not supply detailed answers to those questions. For an organization planning a transition, turn them into decisions specific to its estate:
- Workload boundaries: Which workloads should remain on Terraform, and which are candidates for OpenTofu first?
- Compatibility: Which tool versions, providers, and modules are required by each workload?
- State and recovery: How will state ownership, backups, rollback, and recovery be managed?
- Governance: How will policy enforcement remain consistent across both tools, and who can approve exceptions?
- Evidence of progress: Which operational measures will show whether the transition is meeting your organization’s goals?
These are planning prompts, not reported Talkdesk procedures. The public account establishes the broad strategy—coexistence, familiar workflows, guardrails, and centralized management—but not the technical choices behind it.

The Linux Foundation event page and its video listing do not document a completed Terraform migration, conversion of all state, migration speed, savings, uptime changes, risk reduction, or a specific internal team structure. Nor do they provide a measured comparison showing that OpenTofu is universally preferable to Terraform. The case is best read as a bounded example of how one company described managing both tools while pursuing open-source optionality.
