Cloud infrastructure for
financial services.
Migrate core banking to the cloud, process transactions in real time, ensure disaster recovery that satisfies examiners, and enforce data residency across jurisdictions — with PCI-DSS and SOX compliance built into every layer.
Where financial cloud infrastructure delivers results.
Four infrastructure challenges where we consistently deliver measurable improvements within the first quarter.
Core Banking Cloud Migration
Before
On-premise core banking infrastructure requires 6-month hardware procurement cycles, 24/7 operations staff, and capacity planning that's either wasteful or insufficient. Scaling for product launches takes months.
After
Core banking workloads run on cloud infrastructure with elastic scaling, automated patching, and infrastructure-as-code deployments. New environments spin up in hours, not months. Your operations team focuses on optimization, not hardware maintenance.
60% lower infrastructure TCO
Real-Time Transaction Processing
Before
Transaction processing infrastructure hits capacity limits during peak periods. Batch processing windows keep shrinking as volume grows. Adding capacity requires hardware procurement and data center space. FedNow and RTP readiness is uncertain.
After
Cloud-native transaction processing infrastructure scales automatically with volume. Sub-100ms authorization, event-driven real-time payment routing, and batch processing that completes in a fraction of the current window — all with built-in redundancy.
Sub-100ms authorization latency
Disaster Recovery & Business Continuity
Before
DR relies on a secondary data center that's tested annually — maybe. Failover is manual, runbooks are outdated, and the last DR test revealed gaps that still haven't been remediated. Regulators are asking harder questions.
After
Multi-region active-passive (or active-active) architecture with automated failover, continuous replication, and quarterly DR tests that generate examination-ready reports. RPO and RTO targets are met consistently, not aspirationally.
RPO near-zero, RTO <15 min
Regulatory Data Residency
Before
Data is scattered across on-premise servers, SaaS platforms, and cloud accounts with no consistent classification or residency enforcement. Cross-border data transfers happen without documented legal basis. Regulatory inquiries about data location take weeks to answer.
After
Automated data classification and routing ensures every record lands in the correct jurisdictional region. Cross-border transfers use approved legal mechanisms. Data residency posture is visible in a single dashboard — answering regulatory inquiries takes minutes, not weeks.
100% data residency compliance
Built for financial leaders modernizing infrastructure.
CFOs seeking infrastructure cost reduction
On-premise infrastructure costs are fixed and growing. You need elastic capacity that scales with business volume, predictable billing, and demonstrable TCO reduction — without compromising the control environment your auditors and regulators require.
Heads of Compliance managing examination readiness
Examiners are asking increasingly detailed questions about cloud controls, data residency, and DR capabilities. You need infrastructure that's designed for compliance from the start, with documentation and evidence that satisfies examiner scrutiny.
VPs of Engineering modernizing technology stacks
Legacy infrastructure is holding back product velocity. You need cloud-native infrastructure that lets engineering teams deploy faster, scale automatically, and spend time on product features instead of hardware management.
COOs responsible for operational resilience
Regulators are shifting focus from DR plans to operational resilience — the ability to absorb disruptions and continue serving customers. You need infrastructure that's designed for continuous availability, not just disaster recovery.
From infrastructure audit to production cloud.
Infrastructure Audit
We inventory your current infrastructure, map data flows, classify workloads by criticality and compliance scope, and document the regulatory constraints that will shape the target architecture.
Compliance-First Architecture
We design the cloud architecture around your regulatory requirements — PCI-DSS scoping, SOX controls, data residency, DR targets — then optimize for performance and cost within those constraints.
Phased Migration
We migrate workloads in risk-ordered phases — starting with non-critical systems to validate the architecture, then progressively moving higher-criticality workloads with rollback plans at every stage.
24/7 Monitoring & Optimization
Production environments run with comprehensive monitoring, automated alerting, cost optimization reviews, and quarterly DR testing. Your infrastructure is always audit-ready and continuously improving.
Questions about financial cloud infrastructure.
How do you ensure PCI-DSS compliance in cloud environments?
PCI-DSS compliance in the cloud is about scoping and segmentation, not just checking boxes. We design the cardholder data environment (CDE) as an isolated network segment with strict ingress/egress controls, encrypted data flows, and tokenization at every point where card data could be exposed. We use AWS or Azure PCI-DSS certified services as the foundation, then layer your organization-specific controls on top. Every architecture decision is documented in a Responsibility Assignment Matrix (RAM) that maps shared responsibility between your organization, the cloud provider, and Corsox. We support you through your QSA assessment with architecture documentation, evidence collection, and gap remediation.
How do you handle data sovereignty and residency requirements for multi-region financial institutions?
Data residency is a first-class architectural constraint, not an afterthought. We design multi-region deployments where data classification drives placement — PII stays within jurisdictional boundaries, transaction data routes through compliant processing regions, and cross-border data transfers use approved mechanisms (SCCs, BCRs, or adequacy decisions depending on jurisdiction). We implement automated data classification tagging so new data is routed correctly without manual intervention. For institutions operating across the US, EU, and LATAM, we have direct experience designing architectures that satisfy overlapping requirements from OCC, GDPR, and local regulators simultaneously.
What are the latency requirements for real-time transaction processing in the cloud?
Latency requirements vary by transaction type. Card authorization requires sub-100ms end-to-end processing. ACH and wire transfers are batch-oriented with different timing constraints. Real-time payments (RTP, FedNow) need sub-second processing with guaranteed delivery. We design each processing tier with appropriate infrastructure — in-memory caching for authorization lookups, event-driven architectures for real-time payment routing, and batch-optimized compute for settlement processing. We run load tests that simulate 3x peak transaction volumes to ensure the infrastructure handles growth without latency degradation.
How does disaster recovery work for financial institutions in the cloud?
Financial regulators expect documented RPO (Recovery Point Objective) and RTO (Recovery Time Objective) targets with evidence that you can actually meet them — not just a plan on paper. We design active-passive or active-active multi-region architectures depending on your RTO requirements. Critical transaction processing systems typically need active-active with RPO near zero and RTO under 15 minutes. Supporting systems can use warm standby with RPO under 1 hour. We automate failover testing quarterly and generate compliance-ready DR test reports. Every DR architecture includes runbook automation so failover doesn't depend on a specific engineer being available at 2 AM.
What cost optimization strategies do you use for financial services cloud workloads?
Financial services workloads have predictable patterns that create significant savings opportunities. We use Reserved Instances or Savings Plans for baseline compute (typically 40-60% savings over on-demand), spot instances for batch processing workloads like risk calculations and EOD reporting, and right-sizing analysis to eliminate over-provisioned resources. We implement automated scaling policies tied to transaction volume patterns — scaling up before market open, scaling down after settlement windows close. We also design data lifecycle policies that move aging transaction data to cheaper storage tiers automatically. Most financial institutions we work with see 30-45% reduction in cloud spend within 6 months without reducing capability.
Financial infrastructure expertise — not generic cloud consultants
We understand that financial cloud infrastructure isn't just about migrating workloads — it's about maintaining regulatory compliance, transaction integrity, and operational resilience throughout the transition. You contract with a US LLC (Florida), communicate in your timezone, and get senior cloud architects with genuine financial services experience at 40-60% less than US-only rates through our LATAM delivery center.
