How will you scale for increased AUM and users?
✅ How to Present
🧩 1. Show Deep Alignment Between Tech and Business Goals
“Our microservices-based platform is architected to support ABSLAMC’s key business goals—rapid customer onboarding, product innovation, operational efficiency, and regulatory adherence. Each capability (like onboarding, SIP, portfolio, etc.) is mapped to dedicated microservices, which helps us innovate and scale independently, thus reducing time-to-market for new funds and investor services.”
🔄 2. Stress High Availability, Regulatory Alignment, and Secure Architecture
“We’ve designed for high availability using Azure’s zone-redundant AKS clusters and Azure Front Door for global failover. All investor and transaction data is encrypted at rest and in transit, and access is governed by Azure AD and managed identities. Regulatory alignment with SEBI is achieved via automated compliance checks, immutable audit logs, and data localization through region-specific storage.”
☁️ 3. Emphasize Azure-Native and Cloud-Agnostic Design
“While our solution uses Azure-native services like AKS, API Management, Azure SQL, and App Gateway, all core workloads are containerized, externalized, and decoupled from vendor lock-in. This allows us to lift-and-shift to AWS or GCP with minimal rework using platform-agnostic orchestration tools and IaC (Terraform).”
🛡️ 4. Highlight DevSecOps, Containerization, and Service Mesh
“We’ve embedded security throughout the DevOps lifecycle via Azure DevOps, GitHub Actions, SAST/DAST, and IaC scans. Containers (Docker) enable consistency across environments, and Istio (or Open Service Mesh in Azure) handles service-to-service security, observability, and traffic policies—critical for fault tolerance and zero-trust architecture.”
🧠 Prepare to Answer
❓ Q1. Why Microservices Over Monolith Here?
“Given the wide range of investment products and the need to scale individual services like SIP processing, NAV updates, onboarding, and fraud detection independently, a microservices architecture enables agility, fault isolation, and better DevOps automation. This also allows us to adopt a polyglot approach for optimal performance (e.g., Java for core transactions, Node.js for UI APIs). A monolith would limit flexibility and introduce scaling bottlenecks.”
❓ Q2. How Does Your Design Ensure SEBI Compliance?
“We enforce SEBI compliance at multiple layers:
Data Residency: Investor PII and financial data is hosted in India across compliant Azure regions.
Audit Trails: Immutable logs via Azure Log Analytics and versioned document repositories support audit readiness.
Rule Engines: Policy-as-code ensures compliance with transaction limits, fund caps, and KYC guidelines.
DR and BCP: Fully automated Azure Site Recovery ensures compliance with SEBI's operational continuity mandates.”
❓ Q3. How is Fraud Detection Handled in Real-Time?
“A dedicated fraud-detection-service consumes events via Kafka, enriched with context from onboarding, transaction history, and device data. It runs ML models (via Azure ML or a custom scoring engine) in real-time to detect anomalies like geo-IP mismatch, transaction spikes, or synthetic identities. Alerts are raised to risk ops and can block or flag transactions via circuit breakers and API filters.”
❓ Q4. How Will You Scale for Increased AUM and Users?
“We scale both horizontally and vertically using:
AKS auto-scaling for microservices.
Event-driven scaling via Kafka and Azure Functions for spike-based workloads.
DB partitioning strategies in Azure SQL and Cosmos DB for large AUM handling.
CI/CD pipelines ensure we can release at speed while maintaining stability. Additionally, we use feature flags to gradually roll out new capabilities for different user cohorts.”
✅ 1. Why microservices over a monolith for this mutual fund platform?
Suggested Answer: Microservices offer modularity, agility, and independent scalability—key for a mutual fund platform with dynamic regulatory changes, real-time portfolio updates, and diverse investor personas. Each domain (e.g., NAV calculation, transaction processing, KYC, onboarding) can evolve independently. This aligns with SEBI’s regulatory adaptability and reduces deployment risks.
✅ 2. How does your architecture ensure SEBI compliance?
Suggested Answer: We’ve embedded compliance into architecture using:
Immutable audit trails with Kafka.
Role-based access via Azure AD + Conditional Access.

Data encryption (at-rest and in-transit), meeting SEBI's IRDA/SEBI guidelines.
Regular security scanning in CI/CD pipelines (DevSecOps).
Integration with Azure Purview for data lineage and classification.
✅ 3. How is fraud detection handled in real-time?
Suggested Answer: Fraud detection is implemented as a sidecar microservice:
Ingests transactions from Kafka topics (real-time).
Uses ML-based scoring models deployed via Azure ML.
Suspicious patterns (e.g., unusual AUM spikes, geolocation mismatch) are flagged and pushed to a rule engine.
Integrated with customer 360 to correlate behavior anomalies.
Alerts are sent to fraud management teams and also trigger optional hard holds.
✅ 4. How will you scale for increased AUM and customer growth?
Suggested Answer:
Services are stateless and containerized (Spring Boot on AKS).
Auto-scaling policies per service based on CPU/memory/Kafka lag.
Azure Front Door + Traffic Manager enable geo-distribution.
Multi-AZ, multi-region deployment using Azure Availability Zones.
Azure Cosmos DB & Azure SQL elastic pools ensure horizontal scalability of the data layer.
Caching (Azure Redis) for high-read endpoints like fund NAV, top holdings.
✅ 5. What’s your DevSecOps strategy?
Suggested Answer:
CI/CD via Azure DevOps, including static code analysis (SonarQube), secrets management via Key Vault, container scanning, and IaC validation (Terraform).
Runtime monitoring via Azure Monitor + Prometheus + Grafana.
Service mesh with Istio ensures zero-trust, mTLS, and traffic shaping for chaos testing.
✅ 6. What if you need to move to AWS or GCP later?
Suggested Answer:
Services follow 12-factor app principles and are containerized.
Abstraction at infrastructure level via Helm charts and Terraform for portability.
Messaging via Kafka and DB abstraction layers via JPA/Hibernate.
Common APIs via API Gateway design make cross-cloud migration seamless.
✅ 7. How do you ensure high availability?

AUM stands for Assets Under Management.
🔍 What It Means:
It refers to the total market value of all the financial assets (like mutual funds, stocks, bonds, etc.) that a financial institution or asset management company (like ABSLAMC) manages on behalf of its clients.
✅ In Context of Mutual Funds:
If ABSLAMC manages mutual fund schemes worth ₹3 lakh crore, that ₹3 lakh crore is its AUM.
📌 Why AUM is Important:
It's a key performance metric for mutual fund houses.
Higher AUM = higher trust, larger customer base, more revenue via management fees.
Impacts scalability planning, tech architecture, risk management, and SEBI reporting.
