Case Study: Unlocking Enterprise Sales with Secure On-Premise Deployments in Azure
Table Of Contents
The Challenge: A Major Enterprise Sales Blocker
While working with a leading B2B SaaS provider, we faced a recurring and costly problem: large enterprise customers, particularly in finance and healthcare, loved our product but were unable to use our multi-tenant cloud offering due to their strict data residency and compliance policies. They required our entire SaaS application and their data to reside within their own corporate Azure environment.
Our initial attempts to meet this demand were bespoke, manual, and painful. Each deployment was a unique, multi-month engineering project that was:
- Slow & Expensive: Taking months of engineering time to complete.
- Insecure: Lacking a standardized security posture, creating inconsistent and risky configurations in client environments.
- Unscalable: The process was not repeatable, preventing us from serving a growing pipeline of enterprise customers.
My Solution: A Standardized “On-Premise on Azure” Blueprint
As the lead architect for this initiative, my task was to transform this manual process into a secure, automated, and repeatable product offering. I designed a “SaaS a in a box” blueprint using Infrastructure as Code and modern cloud-native principles.
My key actions included:
- Codifying the Infrastructure: I used Terraform to create a master set of modules that could deploy the entire application stack—including networking (VNet, Subnets, NSGs), compute (Azure Kubernetes Service - AKS), and databases—into a customer’s Azure subscription with a single command.
- Engineering for Secure Access: I implemented Azure Lighthouse and Privileged Identity Management (PIM) to provide our support teams with secure, just-in-time, and auditable access to manage the application without having standing privileges in the customer’s environment.
- Automating Deployments: I packaged the SaaS application into Helm charts and built a CI/CD pipeline using GitHub Actions that could automatically deploy or upgrade a customer’s instance. This pipeline handled everything from provisioning the infrastructure to deploying the latest application version.
The Outcome: A New Revenue Stream and Operational Efficiency
By productizing the on-premise deployment process, we turned a major business challenge into a significant competitive advantage.
- Unlocked a Multi-Million Dollar Pipeline: This new capability immediately unblocked the enterprise sales queue, enabling the company to close several high-value deals.
- 95% Reduction in Deployment Time: The time-to-deploy for a new on-premise customer was reduced from over 2 months to under 3 days.
- Massively Improved Security & Compliance: Every deployment now followed a single, hardened, and auditable security standard, satisfying the requirements of our most demanding financial services clients.
- 60% Reduction in Support Overhead: The standardized and automated nature of the deployments drastically reduced the time our support and engineering teams spent on managing on-premise customer issues.
