AI-NativeThe Infrastructure Problems Slowing Your Business Down
Most cloud migration and modernization projects stall — not from a lack of intent, but from architecture decisions made under pressure. These are the problems Corexta solves before they become production crises.
What You're Dealing With
Legacy Infrastructure Holding You Back
Monolithic applications that can't scale horizontally, require full redeployment for every change, and consume disproportionate infrastructure spend.
Scaling Bottlenecks Under Load
Applications that perform adequately at baseline but degrade under traffic spikes — resulting in incidents, customer complaints, and emergency infrastructure spend.
Deployment Delays Slowing Product Velocity
Manual, fragile deployment processes that take hours, require specialist knowledge, and carry high risk of failure — blocking your team from shipping features quickly.
Cloud Costs Growing Faster Than Revenue
Unoptimized cloud infrastructure — over-provisioned compute, inefficient data transfer, unused reserved capacity, and no visibility into cost attribution by service or team.
Security Posture Risk
Cloud environments configured quickly without a security-first architecture — overly permissive IAM policies, unencrypted data paths, and missing audit trails that create compliance exposure.
No Operational Visibility
Production incidents discovered by customers rather than your own monitoring — no distributed tracing, no SLO alerting, no on-call runbooks, and no structured incident response.

Real Outcomes from Custom Cloud Application Development
These results reflect what happens when cloud applications are built with the correct architecture — not migrated with the wrong one.
B2B SaaS Company Migrates Monolith to Microservices Cloud Architecture
A 200-person SaaS company was running a six-year-old monolithic Rails application that couldn't scale beyond 5,000 concurrent users. Corexta re-architected the platform into 12 microservices on AWS EKS — with a 14-week phased migration and zero customer-facing downtime.
Regional Health Network Builds HIPAA-Compliant Cloud Data Platform
A multi-state health network needed a HIPAA-compliant cloud data platform to process and route 2M+ patient records across facilities. Corexta designed a secure AWS data lake architecture with HL7 FHIR APIs, end-to-end encryption, and full audit logging — delivered in 18 weeks.
Payments Platform Rebuilds Core Processing Infrastructure on Cloud-Native Architecture
A fintech payments company was processing $400M annually on aging infrastructure with growing reliability concerns. Corexta rebuilt their core payment processing platform on a distributed, event-driven AWS architecture — with PCI DSS compliance, 99.99% uptime SLAs, and sub-200ms transaction processing.
What Clients Say About Corexta Cloud Engineering
"Corexta completely redesigned our cloud infrastructure after we hit scaling walls that were threatening our enterprise contracts. The Kubernetes migration they led took our concurrent user capacity from 5,000 to 60,000 without increasing our monthly AWS bill. The architecture quality is genuinely exceptional."
"Building a HIPAA-compliant cloud data platform for a multi-state health network is not a straightforward project. Corexta's cloud architects understood the compliance requirements, the data architecture complexity, and the integration needs from day one. We passed our HIPAA audit with zero findings."
"We chose Corexta over three larger cloud consultancies because they were the only team that came to discovery with an actual architecture position — not just a questionnaire. The CI/CD automation they built has reduced our deployment time from 45 minutes to 4 minutes with zero rollback incidents in 8 months."
"Our logistics platform was running on infrastructure we'd patched together over five years. Corexta migrated us to a properly designed cloud-native architecture in 12 weeks — with a detailed migration plan that kept our 200+ enterprise client operations running without a single disruption during the transition."
"Corexta built our entire multi-tenant SaaS platform on AWS from scratch — including the billing infrastructure, tenant isolation architecture, and the CI/CD pipeline that lets our team deploy three times a day without risk. The observability stack they implemented means we know about issues before our customers do."
"The cloud cost optimization Corexta delivered as part of our modernization project recovered $280K in annual infrastructure spend we were burning through over-provisioned resources. The FinOps governance framework they set up means that kind of waste won't creep back in as we scale."
