Introducing CapNexus…
Where the Strength of Three Industry Leaders Capstone, RPE, and Makira - Become One.
We move workloads to AWS and modernize applications that have been running for decades. We follow a methodology developed by AWS from the learnings of tens of thousands of migrations. Consistent methods at every phase, from assessment through operations.


CapNexus is an AWS Advanced Tier Services Partner with a cloud practice led by over a decade of hands-on AWS experience and a team of AWS-certified engineers. We work across the full AWS stack including compute, storage, networking, database, analytics, AI/ML, and security. We have direct access to AWS technical resources when engagements require it.







Applications that have been running for a decade or more. Java monoliths, tightly coupled .NET systems, aging platforms that are expensive to maintain, difficult to extend, and slow to change. These applications still run core business operations, and replacing them outright isn’t realistic. We modernize them in place: replatforming to managed services, refactoring into microservices, containerizing for portability, or decomposing monoliths into independently deployable components. The approach depends on what each application needs and what the business can absorb.
Assess your application portfolio through a structured engagement model. Identify the right modernization pathway for each workload with outcomes in weeks, not quarters.
Replatform, refactor, containerize, or decompose. The approach depends on the application, its dependencies, and how much change the business can take at once.
We manage the modernized applications in production. You keep your team focused on building, not maintaining.
AS400, IBM i, and mainframe workloads. These systems still run core business operations for many organizations, and the people who built them are retiring. Most cloud consultancies avoid this work because they don’t have the legacy expertise to do it safely. We do. We modernize these environments through data integration, code transformation, or phased migration depending on where the business is today. Sometimes modernization starts by simply unlocking the data trapped in these systems so the rest of the organization can use it. Sometimes it means transforming the applications themselves into modern architectures. The right path depends on the workload, the risk, and the business case.

Assess your mainframe environment and determine the right starting point: data integration, code transformation, or stable hosting.
Connect mainframe data to AWS analytics through federated query, or transform mainframe applications into modern architectures using AWS Transform.
We operate the modernized environment. You stay competitive without the distraction of day-to-day management.

New applications and platforms built on AWS from the ground up. Custom software development, API platforms, containerized microservices, serverless compute, and event-driven architectures. This includes modern intelligent applications that embed AI directly into the product. For organizations that need new capabilities on modern platforms, need to extend what’s already been modernized, or need to build the next generation of AI-powered tools for their teams and customers.
Define architecture, technology stack, integration points, and where AI fits into the application experience.
Build, test, and deploy. Applications designed for the teams that use them, not just the team that built them.
We manage the application long-term with full operational ownership and ongoing support.

Most organizations already have a landing zone and some form of CI/CD. What they don’t have is a coherent internal developer platform. A single foundation where infrastructure, DevOps, security, and observability work together so development teams ship code instead of filing tickets. The result is reduced cognitive load on your engineering teams. Developers stop context-switching between tools, stop waiting on infrastructure requests, and start spending their time on the work that actually moves the business forward.
Assess your landing zone architecture and DevOps maturity. Identify the gaps between where you are and a self-service internal developer platform.
Modernize the landing zone, implement security guardrails, build the CI/CD pipelines and IaC foundations, and integrate it into a single platform your development teams consume as a service.
We operate and evolve the platform 24/7. We manage the application long-term with full operational ownership and ongoing support. You grow confidently knowing it's in good hands.
We migrate production workloads to AWS. Ten servers or ten thousand. Whether it’s a straightforward lift and shift or a complex, multi-platform environment, the methodology is the same. We follow a methodology developed by AWS from the learnings of tens of thousands of migrations. Consistent methods and repeatable results at every phase.

Assess your environment and build a sequenced migration strategy. The right approach for each workload emerges from the assessment, not a predetermined playbook.
Execute in waves prioritized by business impact, with hybrid architectures where needed. We leverage the AWS Migration Acceleration Program (MAP) to offset costs for qualified workloads.
Our operations team runs your migrated environment. You move faster without the operational burden.
We begin every cloud engagement by understanding what you’re running today. No pitch, no predetermined outcome.
An honest look at where you are and what options make sense.
