Core Banking Migration to AWS — Zero Downtime, 40% Cost Reduction
The Challenge
A UK-based private bank with 2.4 million customers was running its core banking platform on ageing on-premise infrastructure. Maintenance costs were escalating, disaster recovery windows were unacceptably long, and the platform could not support the bank's digital product roadmap.
Our Approach
Essex Hornets India designed and executed a phased lift-and-shift migration to AWS, re-platforming the core banking workloads onto a highly available, multi-AZ architecture. We implemented a blue-green deployment strategy to ensure zero downtime during cutover, and introduced automated DR with a 15-minute RTO.
Outcomes Delivered
- 40% reduction in annual infrastructure operating costs
- Zero downtime during the full migration cutover
- Disaster recovery RTO reduced from 6 hours to 15 minutes
- Platform now supports 3x transaction throughput for digital channels
SAP S/4HANA Implementation Across 12 Plants in 18 Months
The Challenge
A Tier 1 automotive components manufacturer operating 12 plants across Europe and Asia was running disparate ERP systems with no unified data layer. Consolidation reporting took 3 weeks per quarter, and inventory visibility across plants was near-zero.
Our Approach
We led the full SAP S/4HANA greenfield implementation — from business process redesign and data migration to go-live support across all 12 plants. Our delivery model used a global template approach with localised configuration for each plant, enabling parallel workstreams and an 18-month programme timeline.
Outcomes Delivered
- Consolidated reporting cycle reduced from 3 weeks to 2 days
- Real-time inventory visibility across all 12 plants
- 18-month delivery against a 24-month industry benchmark
- €2.1M annual savings from procurement process optimisation
End-to-End Digital Claims Platform — 60% Faster Claims Processing
The Challenge
A regional insurance group in the UAE was processing claims through a combination of paper forms, email chains, and a legacy system that required manual data re-entry at every stage. Average claims processing time was 22 days, and customer satisfaction scores were declining.
Our Approach
Essex Hornets India built a cloud-native digital claims platform on Azure — including a customer-facing mobile and web portal, an AI-assisted triage engine, and a workflow automation layer that eliminated manual handoffs. The platform integrated with the group's existing policy management system via a purpose-built API layer.
Outcomes Delivered
- Average claims processing time reduced from 22 days to 8.5 days
- 60% reduction in manual data entry across the claims workflow
- Customer satisfaction (CSAT) score improved from 3.1 to 4.4 out of 5
- Platform handles 100% of new claims digitally — zero paper intake
24/7 Managed Operations for Mission-Critical Logistics Platform
The Challenge
A pan-Asian logistics operator running freight management across 8 countries needed a managed services partner to take over 24/7 operations of their core platform. Their internal IT team lacked the capacity to manage incidents, releases, and infrastructure at the required scale and speed.
Our Approach
Essex Hornets India onboarded as the managed services partner within 6 weeks, establishing a dedicated NOC team, SLA-backed incident response, automated monitoring across 400+ infrastructure components, and a monthly service review cadence with the client's CTO.
Outcomes Delivered
- Platform availability improved from 97.2% to 99.7% within 90 days
- Mean time to resolution (MTTR) reduced from 4.2 hours to 38 minutes
- Zero P1 incidents in the 12 months following full onboarding
- Client internal IT team refocused on product development — not firefighting
Technology Roadmap & Vendor Rationalisation for 28-Hospital Network
The Challenge
A 28-hospital network across South India had accumulated over 60 technology vendors and 14 separate clinical and administrative systems over a decade of growth. The CIO needed an independent assessment and a 3-year technology roadmap to rationalise the estate and prepare for a national expansion.
Our Approach
Our consulting team conducted a full technology estate assessment over 8 weeks — interviewing 40+ stakeholders, auditing all 14 systems, and benchmarking against peer hospital networks. We delivered a prioritised 3-year roadmap, a vendor rationalisation plan reducing the estate from 60 to 18 strategic vendors, and a business case for a unified HIS platform.
Outcomes Delivered
- Vendor estate rationalised from 60 to 18 strategic partners
- Projected 3-year IT cost savings of ₹14 crore identified
- Roadmap adopted by the board and funded in the next budget cycle
- Unified HIS platform selection completed within 6 months of roadmap delivery
Multi-Cloud Architecture Enabling 10x Scale for Series B SaaS Company
The Challenge
A US-based B2B SaaS company had raised a Series B and needed to scale its platform from 200 to 2,000+ enterprise customers within 18 months. Their existing single-region AWS architecture had performance bottlenecks, no multi-tenancy isolation, and a deployment pipeline that took 4 hours per release.
Our Approach
Essex Hornets India redesigned the platform architecture — introducing multi-region deployment across AWS and GCP, Kubernetes-based container orchestration, tenant isolation at the infrastructure layer, and a CI/CD pipeline reducing release cycles from 4 hours to 22 minutes.
Outcomes Delivered
- Platform scaled from 200 to 2,200 enterprise customers in 16 months
- Release cycle reduced from 4 hours to 22 minutes
- 99.99% uptime SLA achieved and maintained post-scale
- Infrastructure cost per customer reduced by 34% through right-sizing
