Tarmac.io & HAVI at a glance:
Industry: Logistics (Food & Beverage)
Engagement: 1+ year (ongoing)
Team: 3 Tarmac engineers embedded with 2 internal team members
Key Challenge: Siloed systems, lack of visibility, security risks during transformation
Technologies: Azure Resource Inventory · Azure Advisor · Terraform · Terragrunt · GitHub
The Challenge
During a broader organizational transformation, the company was challenged with the following:
1. Poor visibility across systems2. Security and compliance gaps.
3. Cost inefficiencies and technical debt
Tarmac's Approach
Tarmac conducted a comprehensive DevOps Audit and co-designed a roadmap to modernize their Azure environment.
Methodology:
✓ Evidence-based audit with global read-only access
✓ 2-week Agile sprints
✓ Prioritized remediation roadmap (0–3–6–12 months)
✓ Long-term modernization plan (3–5 years)

HAVI needed to gain control, improve security, and optimize cloud costs quickly.
More than just a ‘black box’! Everything around it was also pitch black. We had zero visibility into things like: How many databases are there? How many servers do we have? Firewalls? What does our security look like? What are our risks?

Solution
The proposed solution was to conduct a comprehensive, yet easily consumable DevOps Audit. The report was to incorporate proper documentation alongside graphs, network maps & images. Furthermore, it would include short-term “quick wins” (3, 6, 12 months) as well as a long-term roadmap (3-5 years).
The company’s restructuring and instability meant that this would not be a “simple” consulting project following a “Requirements → Proposal → Delivery” model. The Director couldn’t rely on traditional consulting; they needed people who would “wear the shirt of the company”.
There was a lot of uncertainty, a lot of things that needed to be done to chart our path. It was never like ‘Tarmac is coming here to do this, this, and this.’ It was a lot of mutual exploration and discovery. From my experience with other companies, when a consultant is in an environment where they have to sink or swim, they usually sink. With Tarmac, it was the opposite.
