Engineering Principles For Building A Successful Cloud-Prem Solution
InfoQ, Thursday, June 26th, 2025
Cloud-Prem solutions, often called Private Software as a service (SaaS) or Bring Your Own Cloud (BYOC), blend the advantages of cloud software with on-premises control. In a Cloud-Prem model, a vendor's service is deployed into the customer's own environment (their cloud account or data center) but remains vendor-managed.
Cloud-Prem, which includes Bring Your Own Cloud (BYOC), is an architectural approach that splits control and data planes, giving customers cloud-like service with their data and infrastructure under their control. Cloud-Prem is rising in popularity in response to data sovereignty, compliance, and cost drivers in the AI and enterprise space.
When architecting a Cloud-Prem solution, design for portability and repeatability from the outset by packaging the service in containers, orchestrating it with Kubernetes, and delivering it through infrastructure-as-code, operators, and GitOps/CI-CD pipelines so that any target environment can be deployed automatically.
Anticipate the operational challenges of many isolated customer instances by building consent-based telemetry, providing scripted diagnostic tooling, and automating upgrades to maintain visibility and reliability without direct access.
Use a zero-trust mindset with least privilege access for the vendor in customer environments with clear boundaries while also facilitating safe vendor access for troubleshooting (e.g., JIT support tunnels), because completely hands-off support is impractical.
Supporting Cloud-Prem means a different pricing model (subscription for software only, customer pays infra costs) and targeting high-value enterprise use cases, and aligning product strategy, engineering investment, and sales approach to make Cloud-Prem sustainable by reinvesting in automation to offset higher support costs and sustain healthy margins.
