Enterprise cloud migration is far more than a technical lift-and-shift. Without the right strategy, architecture and governance, migration projects stall, overspend and risk operational continuity. These are the critical challenges we address.
Monolithic applications with undocumented dependencies, tightly coupled middleware and hardcoded on-premise integrations make cloud migration technically complex and high-risk without proper discovery.
Organizations routinely underestimate cloud spend by 30—50% due to incorrect sizing, unused resources, data egress costs and failure to optimize licensing — eroding the expected ROI from migration.
RBI data localisation mandates, DPDP Act 2023 and sector-specific regulations impose strict controls on where data can reside and how it must be protected — requiring careful cloud region and architecture decisions.
Mission-critical systems — core banking, ERP, SCADA — cannot sustain downtime during migration. Without a validated cutover strategy and rollback plan, organizations face unacceptable operational risk.
Most enterprise IT teams lack cloud-native skills in containerization, DevOps, FinOps and cloud security. Poorly managed change leads to resistance, shadow IT and failure to realize cloud's full potential.
Misconfigurations, over-privileged IAM roles, exposed APIs and absence of cloud-native security guardrails routinely lead to data exposure incidents — particularly in rushed migration scenarios.
Every OneCloud migration begins with a structured four-phase assessment that gives you a complete picture of your existing environment — applications, infrastructure, data, security posture and compliance obligations — before a single workload moves to cloud.
Our certified cloud architects use the AWS Migration Acceleration Program (MAP), Azure Migrate framework and Google Cloud's migration methodology to produce a business-justified cloud roadmap aligned to your strategic objectives.
Automated discovery of all applications, servers, databases and network dependencies using agent-based and agentless tooling. We map every application to its business function, SLA requirements, data classification and regulatory obligations.
Each application is assessed for cloud suitability — retire, retain, rehost, replatform, refactor or rebuild — with a detailed Total Cost of Ownership model comparing current on-premise costs with projected cloud spend over 3 years.
Target architecture design covering network topology, landing zone configuration, identity and access management, security controls, disaster recovery and compliance guardrails — reviewed and approved before migration begins.
A phased, risk-prioritized migration roadmap with wave planning, resource requirements, governance framework and success metrics. Delivered as both a technical blueprint and a board-level business case with investment justification.
Not all applications migrate the same way. Our architects apply the proven 7R framework — tailored to each workload's technical profile, business criticality and modernization opportunity — to maximize value while minimizing risk.
Move applications to cloud with minimal changes — ideal for workloads that need rapid migration or where modernization is planned for a subsequent phase. Achieves speed and quick wins in infrastructure cost savings.
Move to cloud while making targeted optimizations — switching to managed database services, containerizing middleware or adopting cloud-native load balancing — without full re-architecture.
Redesign applications to leverage cloud-native capabilities — microservices, serverless, managed services and auto-scaling. Recommended for strategic applications where agility and scalability deliver competitive advantage.
Replace legacy applications with SaaS equivalents or managed cloud platforms — eliminating maintenance burden, accelerating capability adoption and shifting to an opex model aligned to business consumption.
Some workloads must remain on-premise for regulatory or latency reasons. We design secure, high-bandwidth hybrid connectivity (AWS Direct Connect, Azure ExpressRoute) so on-premise and cloud operate as a unified environment.
Our structured six-stage migration execution framework ensures every workload is migrated safely, validated thoroughly and optimized for cloud performance — with zero compromise on business continuity.
Landing zone provisioning, IAM baseline, networking foundation, security guardrails and migration tooling deployment. Validate connectivity and access before any workload moves.
Migrate non-critical workloads first to validate tools, runbooks, performance and security in the target environment. Refine approach before tackling business-critical systems.
Phased migration of production workloads following tested runbooks. Each wave includes pre-migration validation, parallel-run testing, cutover execution and immediate post-cutover monitoring.
Post-migration validation against performance baselines, security posture assessment and a 30-day hypercare period with dedicated monitoring and rapid-response support to stabilize the new environment.
Migration is the beginning, not the end. Our Cloud Optimization practice continuously improves your cloud environment — reducing cost, improving performance and hardening security posture through automated governance and FinOps discipline.
Continuous rightsizing recommendations, reserved instance planning, savings plan optimization and chargeback reporting — typically delivering 25—40% reduction in cloud spend within 90 days of engagement.
Application performance profiling, database query optimization, CDN integration and intelligent auto-scaling policies — ensuring your cloud environment performs at peak efficiency under variable load conditions.
Continuous scanning for misconfigurations, IAM over-privilege and compliance violations across AWS, Azure and GCP. Automated remediation workflows ensure your cloud environment stays secure and compliant.
Containerize legacy applications and manage them on AWS EKS, Azure AKS or GCP GKE. We implement GitOps, CI/CD pipelines and cluster security policies to enable cloud-native development practices.
Cloud-native DR using AWS Site Recovery, Azure Site Recovery or GCP Cloud Disaster Recovery. Regular DR drills, RTO/RPO validation and automated failover testing ensure your business continuity objectives are met.
Full-stack observability with metrics, logs and traces using CloudWatch, Azure Monitor, Datadog or Dynatrace. AIOps-powered anomaly detection and predictive alerting reduce incident resolution time by over 60%.
Post-migration, our Managed Cloud Services team takes full operational responsibility for your cloud environment — monitoring, patching, cost governance, security and incident management — so your IT team can focus on innovation.
Round-the-clock monitoring of all cloud resources — compute, storage, networking, databases and applications — with automated alerting, incident creation and escalation to on-call engineers.
Automated OS and middleware patching with change advisory board process, rollback capability and compliance evidence generation. Zero-touch maintenance windows minimize operational disruption.
Monthly cloud cost review, budget alerting, utilization reporting and continuous optimization recommendations. Chargeback and showback reporting for business units with cloud spend allocation.
Tiered incident management with contractual SLAs — P1 incidents acknowledged within 15 minutes, resolved within 4 hours. Dedicated account management and monthly service review meetings.
Real, measurable business outcomes delivered through OneCloud Migration engagements across BFSI, Government and Manufacturing sectors in India.
Cloud-native auto-scaling enables enterprises to handle peak loads — year-end banking transactions, e-commerce surge events, government portal launches — without over-provisioning permanent capacity at significant cost.
Cloud environments designed to RBI, DPDP Act and ISO 27001 standards from day one. Automated security guardrails and continuous compliance monitoring replace manual audit cycles and reduce regulatory risk.
Eliminate large upfront hardware refresh cycles. Cloud shifts IT spend from capital expenditure to operational expenditure — improving cash flow, enabling more predictable budgeting and aligning IT cost to actual business consumption.

Speak to a Cloud ArchitectTimeline depends significantly on the size and complexity of your application portfolio. A typical mid-size enterprise with 50—150 applications takes 12—24 months for a full migration programme, executed in waves. Our approach begins with a 4—6 week assessment and planning phase, followed by a 4—8 week pilot wave, then production waves of 6—10 applications per 4—6 week cycle. Organizations with simpler environments or that focus on rehost-only migrations can complete significantly faster.
Yes — we have helped 20+ BFSI organizations achieve cloud adoption while maintaining full RBI compliance. AWS, Azure and GCP all have India regions (Mumbai and Hyderabad) that satisfy RBI's data localisation requirements for payment data and core banking records. We design cloud architectures with data residency controls, appropriate replication restrictions and audit logging that satisfies RBI examination requirements. We also assist clients in preparing their cloud deployment for RBI IT examination.
Every migration wave includes a documented, tested rollback plan that can be executed within 2—4 hours for most workloads. Our 30-day hypercare period provides dedicated engineering support after each cutover — with P1 incident response within 15 minutes. We also maintain the source environment in a preserved state for a minimum of 30 days post-cutover specifically to enable rapid rollback if required. In 500+ workload migrations, we have successfully rolled back 3 waves — all within the planned rollback window.
We support all cloud deployment models — single cloud, multi-cloud and hybrid cloud. Many of our enterprise clients operate a hybrid model permanently, keeping certain regulated workloads on-premise while running modern applications on public cloud. We design secure, high-availability connectivity between environments using AWS Direct Connect, Azure ExpressRoute or GCP Interconnect, managed through SD-WAN where appropriate. Our cloud management platform provides unified visibility and governance across all environments.
Cloud cost governance starts during the migration planning phase — we size workloads accurately using performance data from the assessment, recommend reserved instances and savings plans for steady-state workloads, and implement budget alerts from day one. Post-migration, our FinOps team provides monthly cost reviews with specific rightsizing recommendations, unused resource identification and savings plan optimisation. Clients consistently achieve 25—40% cost reduction within 90 days of going live compared to initial cloud spend.
