Data Residency

Where your data lives matters — for compliance, performance, and sovereignty. Alchemilla Ventures helps organisations implement data residency strategies that keep sensitive data within national borders.

The Data Residency Imperative

the regulatory landscape increasingly mandates data localisation. The RBI requires payment system data to be stored only . IRDAI mandates local data storage for insurance. The DPDP Act 2023 imposes data protection obligations with cross-border transfer restrictions. For enterprises, data residency is not optional — it’s a legal requirement.

Our Data Residency Services

• Data Residency Strategy & Assessment: We begin with a comprehensive data mapping exercise — what data do you collect, where is it stored, where does it flow, and who has access? Our consultants classify data against regulatory requirements (personal, sensitive personal, financial, health) and identify residency gaps. The output is a data residency strategy document with an implementation roadmap.

• Regional Cloud Architecture: Design and migrate workloads to cloud regions within your jurisdiction — AWS (Mumbai, Hyderabad), Azure, GCP (Mumbai), and local cloud providers. We architect for data residency compliance while maintaining the performance and scalability benefits of cloud.

• On-Premise & Colocation Solutions: For organisations that cannot or choose not to use public cloud, we design on-premise or colocation solutions in data centres — CtrlS (Mumbai, Hyderabad), STT (Mumbai, Bengaluru), Yotta (Navi Mumbai, Greater Noida), or NTT Netmagic (Mumbai, Bengaluru). Our team manages the full lifecycle — data centre selection, hardware procurement, installation, and ongoing management.

• Sovereign Cloud & Government Community Cloud: For government and PSU clients, we implement solutions on MeitY-empanelled cloud providers and government community clouds. We navigate the complex procurement and compliance requirements of government IT projects.

• Cross-Border Data Transfer Controls: Implement technical controls that prevent unauthorised cross-border data flows — DLP policies, geofencing, encryption, and access controls. We configure Microsoft 365, Google Workspace, and SaaS platforms to respect data residency requirements. For global enterprises with shared services centres, we design information barriers that keep sensitive data local while enabling global collaboration.

• Data Residency Validation & Auditing: Regular validation that data residency controls are effective — automated compliance checks, data flow monitoring, and periodic audits. We provide reports suitable for regulatory submissions and board presentations.
