B2B Software Consulting in Hyderabad
Hyderabad is the only Indian city other than Mumbai with its own AWS Region — ap-south-2, three Availability Zones, live since 21 November 2022. ERPStack is remote-first and builds validated systems for the HITEC City and Gachibowli life-sciences cluster: ERP audit trails answerable to 21 CFR Part 11 and EU GMP Annex 11, hosted in Hyderabad itself.
Quick Answer
In short: Hyderabad is the only Indian city besides Mumbai with its own AWS Region, ap-south-2. ERPStack builds life-sciences ERP there: 21 CFR Part 11 audit trails, EU GMP Annex 11 computerised-system controls, DPDP Act residency, and a Rule 13 impact assessment every twelve months, with ap-south-1 about 14 ms away for recovery.
Regional Compliance
- FDA 21 CFR Part 11 Compliance (electronic records and signatures)
- EU GMP Annex 11: Computerised Systems (operative 30 June 2011)
- Digital Personal Data Protection Act, 2023 (No. 22 of 2023)
- Data residency in AWS ap-south-2 (Hyderabad), 3 Availability Zones
- Rule 13, DPDP Rules 2025: Significant Data Fiduciary DPIA and audit every 12 months
- Auditable against SOC 2 and ISO 27001 for sponsor and customer audits
Security & Compliance Architecture
A Hyderabad life-sciences ERP answers to two regimes that pull in opposite directions: GxP wants records kept and traceable, and the Digital Personal Data Protection Act, 2023 wants personal data erased on request. The Digital Personal Data Protection Rules, 2025 date the collision — sections 3 to 17 of the Act bind from 13 May 2027 — so resolving it in PostgreSQL is an engineering job with a deadline.
Erasure meets retention, and retention wins — if you can prove it
Section 8(7)(a) obliges a Data Fiduciary to erase personal data when consent is withdrawn, but only unless retention is necessary for compliance with any law for the time being in force. For a CRO in Genome Valley, where 250+ life-sciences companies from 18 countries share one campus, that is the whole game: the ERP needs a legal-hold predicate outranking the erase job, citing the retaining statute per record, and writing every refusal into the audit trail. We model it in PostgreSQL and Redis with RBAC over who may lift a hold, and expose the decision as a REST API a Hyderabad quality unit can audit.Periodic evaluation is a scheduled job, not an annual scramble
Annex 11 clause 11 requires computerised systems to be evaluated periodically to confirm they remain valid, clause 10 requires controlled change management, and clause 4.8 requires migration checks proving data were not altered in value or meaning. ERPStack wires that into CI/CD Deployment Pipelines: GitHub Actions attaches the change record, Vitest and Playwright evidence to every Hyderabad release, and a Drizzle ORM migration diff runs against the production shape before cutover.A large Hyderabad pharma is a Significant Data Fiduciary candidate
Section 10(2) obliges a Significant Data Fiduciary to appoint a Data Protection Officer based in India and answerable to the board, appoint an independent data auditor, and run Data Protection Impact Assessments — and Rule 13 of the Digital Personal Data Protection Rules, 2025 fixes that at once every twelve months, with significant observations reported to the board. The Schedule reaches ₹150 crore for breaching section 10 and ₹250 crore for failing safeguards under section 8(5), from 13 May 2027. A Hyderabad ERP on Multi-tenant Architecture should generate DPIA evidence, not store a slide about it.Every new Region is a re-qualification event
Two hyperscaler regions inside Hyderabad help only if infrastructure is treated as part of the validated system. Annex 11 states that the application should be validated and the IT infrastructure qualified, so moving a Hyderabad workload from AWS ap-south-2 to Microsoft Azure India South Central is a qualification exercise with its own installation and operational evidence. Terraform and Docker keep that reproducible, so a Cloud Migration for a Hyderabad plant is a re-run rather than a rewrite.
Engineering Blueprint
Hyderabad is the only Indian city besides Mumbai with an AWS Region of its own, and for a buyer in Telangana’s life-sciences cluster — 40% of India’s pharmaceutical production and more than 250 USFDA-approved manufacturing sites — that changes the argument. AWS’s Asia Pacific (Hyderabad) Region, ap-south-2, has run 3 Availability Zones since 21 November 2022, and Microsoft Azure’s India South Central region, also in Hyderabad, adds a second hyperscaler. ERPStack is remote-first and builds the validated ERP that runs inside them, in Next.js, TypeScript, PostgreSQL and Drizzle ORM, with RBAC and the audit trail designed in from the first migration.
ap-south-2 is opt-in, so residency is a Terraform decision
ap-south-2 is disabled by default on every AWS account, because AWS requires an explicit opt-in for any Region introduced after 20 March 2019. A Hyderabad ERP therefore starts with an account-level enable, a service control policy pinning workloads to it, and Terraform providers aliased per Region. We keep the primary PostgreSQL cluster in ap-south-2 behind a Bastion Host, ship Docker images through the same pipeline, and stream replicas to ap-south-1 in Mumbai — about 14 ms away by continuous measurement — so a Hyderabad manufacturer gets disaster recovery without a byte leaving India.
The audit trail is a table, not a log file
FDA 21 CFR Part 11 Compliance turns on §11.10(e): secure, computer-generated, time-stamped audit trails recording the date and time of operator entries that create, modify or delete electronic records — and changes must not obscure previously recorded information. EU GMP Annex 11 clause 9 asks for the same system-generated record, and clause 12.4 wants the operator identity on every change. In a Hyderabad ERP that makes the Immutable Audit Trail a PostgreSQL table written by a trigger and stripped of UPDATE and DELETE grants, with RBAC deciding who may even read it.
-- 21 CFR 11.10(e): prior values are never obscured
CREATE TABLE batch_audit (
record_id uuid NOT NULL,
actor text NOT NULL,
old_value jsonb,
new_value jsonb NOT NULL,
reason text NOT NULL,
signed_at timestamptz NOT NULL DEFAULT now()
);
REVOKE UPDATE, DELETE ON batch_audit FROM erp_app;Electronic signatures that survive an inspection
§11.50 requires every signed electronic record to carry the printed name of the signer, the date and time of signing and the meaning of the signature; §11.70 requires the signature to be linked to its record so it cannot be transplanted onto another. Annex 11 clause 14 says the same: permanently linked, time and date applied. A Hyderabad ERP that renders a signature into a PDF fails both. We store each signature as a PostgreSQL row, hash the canonical payload, validate it with Zod in TypeScript, and expose verification over a REST API — so a re-signed batch record is detectable in one call.

Frequently Asked Questions
Yes, materially. ap-south-2 is Asia Pacific (Hyderabad) with 3 Availability Zones, so a Hyderabad company can keep primary PostgreSQL, object storage and backups inside its own city rather than in Mumbai. We still replicate to ap-south-1 for disaster recovery, roughly 14 ms away, which keeps both AWS copies of the ERP inside India.
A custom ERP can be validated, and Annex 11 clause 4.6 addresses bespoke and customised computerised systems directly. No vendor ships a validated system — not SAP, not Oracle NetSuite, not Odoo, not Microsoft Dynamics 365 — they ship software you validate. The honest trade is effort: a packaged ERP arrives with test scripts, while a Hyderabad custom build needs its own URS, IQ, OQ and PQ evidence.
Who did what, when, and what it was before. That is §11.10(e) — a secure, computer-generated, time-stamped audit trail that does not obscure previously recorded information — plus §11.10(d) limiting access to authorised individuals and §11.10(b) the ability to produce accurate and complete copies in human-readable and electronic form. For a Hyderabad site we build all three into the PostgreSQL schema, with RBAC over the audit trail itself.
Either, but pick one and qualify it. AWS ap-south-2 has been generally available since 21 November 2022 with 3 Availability Zones; Microsoft Azure's India South Central region, headquartered in Hyderabad, was announced in December 2025 with three availability zones and a mid-2026 go-live. For a validated ERP the deciding factor is usually which cloud your sponsors already accept.
As a change-controlled interface, not a plugin. Every API call that sends an invoice to the Invoice Registration Portal and stores the returned IRN is a GMP-relevant transaction in a Hyderabad ERP, so the request, response and failure path all land in the audit trail. Tax-side schema changes then run the same qualification as any other release.
§11.10(e) requires secure, computer-generated, time-stamped audit trails that independently record the date and time of operator entries and actions creating, modifying or deleting electronic records, that record changes must not obscure previously recorded information, and that the audit trail is retained at least as long as the record itself. In a Hyderabad ERP that means an append-only PostgreSQL table, declared in Drizzle ORM, with UPDATE and DELETE revoked.
Retention, when a statute demands it. Section 8(7)(a) of the Digital Personal Data Protection Act, 2023 requires erasure on withdrawal of consent unless retention is necessary for compliance with any law in force. A Hyderabad CRO — often also inside a HIPAA business-associate chain for US sponsors — needs a legal-hold predicate in the ERP that names the retaining statute per record and logs every refused erasure.
Periodically, and Annex 11 clause 11 leaves the interval to your risk assessment while naming what it must cover: current functionality, deviation records, incidents, problems, upgrade history, performance, reliability, security and validation status. A Hyderabad ERP can emit most of that automatically — Sentry for incidents, GitHub Actions and Vitest for upgrade history, the PostgreSQL audit trail for security events.
If your processes match pharma industry templates, SAP S/4HANA is the lower-risk buy and we will say so; Oracle NetSuite and Microsoft Dynamics 365 win on the same logic. The case for a custom ERP in Hyderabad appears when the differentiator is the process itself — a CDMO billing model per campaign, or lab and plant data an ERP was never designed to hold.
It can be notified as one, and the duties are concrete. Section 10(2) requires a Data Protection Officer based in India answerable to the board, an independent data auditor, and periodic Data Protection Impact Assessments. Breaching those reaches ₹150 crore under the Schedule, against ₹250 crore for failing reasonable security safeguards. A Hyderabad ERP should generate DPIA evidence rather than store it.
The professional tax table. Telangana's Tax on Professions, Trades, Callings and Employments Act, 1987 runs three bands — nil up to ₹15,000 a month, ₹150 from ₹15,001 to ₹20,000, ₹200 above ₹20,000 — where Karnataka has one ₹200 slab above ₹25,000. India's four labour codes took effect on 21 November 2025 and the saved EPF and ESI schemes run only to 21 November 2026, so a Hyderabad ERP must version payroll rules by effective date in PostgreSQL.
