SaaS Architecture Advisory for No-Code Solution

@B1zt

Hi there, For a GxP system with per-site processes, the isolation boundary needs to sit exactly where your compliance and restore boundary sits. If a single site has to be validated, audited or restored on its own, that site has to be separable in the data layer, and no amount of application-level filtering will stand up to an auditor later. That one decision drives your environments, your backup story, your cost curve and most of the other answers on your list, so it should be settled first. I build a multi-tenant identity SaaS, so tenancy models, customer and sub-customer hierarchies, and keeping one customer's data properly fenced off from the next are what I work on daily. For INR 10,000 you get: - A written recommendation on the tenancy model for your case, with the trade-offs of each option stated in plain terms rather than in the abstract - The customer, site and environment layout: how many databases, what is shared, what is separated, and why - A clear answer on whether a single site can be backed up and restored on its own under your chosen model - A call to walk through it and pressure-test it against how your product actually works Delivered within one week. The full twelve-point review and target diagram is a larger piece I would rather quote once the tenancy call is made, since the rest hangs off it. One question: does a site ever get validated or audited on its own, or is validation always done at the corporate customer level? Talk soon, Bhagya

Hello, I can help with the cloud and infrastructure aspects of your SaaS architecture. I have hands-on experience with Azure, Linux, Docker, Kubernetes, Terraform, Ansible, and cloud infrastructure automation. I can help evaluate practical options for multi-tenancy, tenant and site isolation, database and environment strategy, containerization, security, backup and disaster recovery, and scalable cloud infrastructure. I can also provide a clear target architecture and explain how to start with a cost-effective design that can scale as the number of customers grows. I am available to discuss your current architecture, requirements, and expected deliverables before starting.

Hi — GxP is the constraint that decides most of your twelve questions, so I'd lead with it rather than answer them in isolation. A concrete opinion up front, so you can judge whether I'm worth talking to: Hybrid multi-tenancy is probably right, but the split shouldn't be by customer size — it should be by validation boundary. Under GxP, a change to a shared schema forces revalidation for everyone on it. So shared schema for configuration and catalogue data, separate schema per customer for process and record data, because that lets one customer revalidate without dragging the others through it. Sites become rows inside the customer's schema, not separate tenants — site-level tenancy multiplies your validation surface roughly tenfold for isolation you can already get with RBAC. That also answers the environment question: DEV and VALIDATION shared, PROD isolated per customer, with configuration promoted as versioned artefacts rather than by DB copy. A DB copy carries record data across an environment boundary, which auditors flag. I'd deliver the full set as a written architecture: target diagram, per-question recommendations, and a cost model at 1/10/50/100/500 customers. Questions: 1. Which GxP scope — 21 CFR Part 11, EU Annex 11, or both? 2. Cloud already chosen, or genuinely open? 3. Expected first-year customer count? Ronak — AWS and Azure certified Solutions Architect.
