NORFOLK / HAMPTON ROADS

Modernize Legacy Systems for Mission Readiness

We are a Service-Disabled Veteran-Owned Small Business (SDVOSB) specializing in migrating critical defense and enterprise applications to secure, modern cloud platforms.

Veteran-Owned SDVOSB
001 / 005 Field Conditions

Legacy systems are a liability to mission-critical operations.

Situation

Many core logistics and maintenance systems in the Hampton Roads area run on brittle, decades-old code. These monolithic applications are difficult to update, vulnerable to security threats, and can't integrate with modern data platforms. The result is operational friction, high sustainment costs, and an inability to adapt. A failed deployment or security breach isn't an inconvenience; it's a risk to the mission. These systems weren't built for the current operational tempo, and patching them is no longer a viable strategy. True modernization is a requirement, not a preference.

  • Fragile COBOL or Java 1.6 codebases that break on minor changes.
  • Security vulnerabilities from unpatched, out-of-support platforms.
  • Inability to integrate with modern APIs for logistics or C5ISR systems.
  • Slow, manual deployment cycles measured in months, not hours.

002 / 005 Operational Approach

A phased, low-risk approach to system modernization.

  1. STEP-01

    System Audit and Triage

    We conduct a deep analysis of the existing system's architecture, code quality, and operational risks. This builds a data-driven modernization roadmap, identifying components to refactor, replace, or retire. No guesswork.

  2. STEP-02

    Target Architecture Definition

    We design a cloud-native or hybrid architecture on AWS GovCloud or Azure Government that meets all security, compliance (CMMC, FedRAMP), and performance requirements for your specific mission and data.

  3. STEP-03

    Strangler Fig Implementation

    We incrementally replace legacy components with new microservices, routing traffic piece-by-piece. This strategy minimizes disruption to live operations and avoids the high risk of a single, 'big bang' cutover.

  4. STEP-04

    Data Migration and Validation

    We securely migrate critical data from legacy databases like Oracle or DB2 to modern platforms. We ensure total data integrity and zero operational downtime through automated, repeatable validation scripts and controlled synchronization.

003 / 005 Common Questions

Field FAQ.

→ What makes VooStack different for Norfolk-based DoD work?

As an SDVOSB with a local Hampton Roads presence, we understand the mission. Our engineers have direct experience with Navy and shipyard systems. We don't just write code; we deliver durable, mission-focused solutions built to withstand the long sustainment cycles common in defense. We combine operator perspective with senior engineering talent.

→ Can you work inside secure facilities or with CUI?

Yes. Our personnel can meet the requirements for working within secure government facilities. We have extensive experience architecting and operating systems within AWS GovCloud and Azure Government to handle Controlled Unclassified Information (CUI) and meet stringent DoD compliance standards like CMMC 2.0 and DISA STIGs.

→ Do you replace systems entirely or refactor them?

Our approach depends on a cost-benefit analysis of the specific system. We often use the 'strangler fig' pattern to incrementally replace high-risk or high-value functions with new microservices, de-risking the project. A full rewrite is a last resort; we prioritize the path that delivers value fastest while ensuring operational stability.

→ How do you handle legacy systems with minimal documentation?

This is standard procedure for us. We use a combination of static code analysis tools, reverse-engineering techniques, and structured interviews with incumbent subject matter experts. We map the system's actual behavior and dependencies to create the documentation that should have existed, establishing a factual baseline before modernization begins.

→ What's your experience with shipyard or maintenance logistics software?

We have specific experience modernizing systems in this domain. We understand the unique challenges: complex hardware and sensor integrations, the need for high-availability in industrial environments, and the long-term sustainment requirements. We build systems designed for durability and ease of maintenance by government or prime contractor teams.

→ Are your engineers based locally in Hampton Roads?

We anchor our project teams with senior engineers on-site in the Norfolk area to ensure high-bandwidth communication with stakeholders. This core team is supported by our broader roster of cleared, U.S.-based senior engineers who can operate remotely within secure environments. This provides both local presence and scalable expertise.

→ How does being an SDVOSB benefit federal clients?

Partnering with an SDVOSB provides federal agencies with streamlined procurement pathways, including sole-source awards and set-aside contract eligibility. Beyond the acquisition benefits, you get a partner with a deep, personal commitment to the mission. We've been on the user side of these systems and are driven to make them better.

→ What cloud platforms do you specialize in for government work?

We focus on AWS GovCloud and Microsoft Azure Government. Our expertise is not just in basic cloud services, but in the specific security, identity, and compliance tooling required for DoD workloads, including implementing Infrastructure as Code, robust CI/CD pipelines, and adhering to FedRAMP and DISA security controls.
