AWS Security Compliance on a Critical Deadline with Zero Downtime

Case Study

A national childcare management platform faced an urgent regulatory deadline: AWS would soon deprecate older TLS protocols, putting millions of customer records and contractual SLAs at risk. With only months to spare and no internal bandwidth to manage a legacy application, they turned to DevIQ to deliver a zero-downtime migration to modern cloud infrastructure, stabilize operations, and preserve revenue – ensuring uninterrupted service for their largest customers.

The Client & The Challenge

A leader in childcare software, this SaaS provider enables early education centers to securely communicate with families and manage daily operations. While their primary platform had moved forward, a major segment of their enterprise customers remained on a legacy application with highly customized features.

A Looming Compliance Crisis

  • Regulatory Pressure – AWS announced a firm deprecation deadline for legacy TLS encryption, putting continued access for two of the provider’s largest clients in jeopardy.
  • Technical Debt – The legacy app was several generations behind on critical libraries and cloud infrastructure, making direct upgrades risky and time-consuming.
  • Resource Constraints – Internal teams lacked capacity and expertise to oversee a high-stakes upgrade, especially with a distributed offshore team working on the application code.

Consequences of Inaction

Failure to meet the AWS deadline would have resulted in immediate service outages, violation of contractual SLAs, and likely customer churn from the provider’s most valuable accounts.

The Partnership & The Proposition

Brought in as a technical guide through a trusted consultancy partnership, DevIQ quickly embedded with the client’s teams. Our mandate: execute a high-stakes cloud migration, stabilize the legacy application, and provide technical leadership for distributed development resources—all with zero disruption to end users.

Rapid Integration and Expert Oversight

  • Immediate Impact – DevIQ resources rapidly assessed the existing infrastructure, scoped a path to compliance, and took ownership of the migration project.
  • Technical Leadership – Provided oversight to offshore teams, implemented robust code review practices, and ensured that all changes aligned with compliance and operational best practices.
  • Collaborative Extension – Fully integrated into daily standups and client communication, DevIQ acted as both architect and project driver, bridging gaps between business goals and engineering execution.

DevIQ’s reputation for swift execution, technical depth, and consultative problem-solving made us the clear choice for this urgent engagement.

The Solution

Strategy & Approach

DevIQ led a two-pronged approach: upgrade cloud infrastructure to meet new AWS requirements, and coordinate application code updates to ensure end-to-end compliance.

Business-Driven Execution

  • Risk Mitigation – Prioritized customer continuity and zero downtime, structuring all changes around business impact and contractual SLAs.
  • Clear Process Ownership – Assumed project leadership, reducing strain on internal teams and freeing up key resources to focus on core business initiatives.

Technical Execution

Cloud-Native Modernization
  • AWS ECS Migration – Built new, compliant container infrastructure in AWS Elastic Container Service, leveraging AWS Fargate for serverless, on-demand scalability.
  • Zero-Downtime Cutover – Designed and executed a canary deployment, gradually shifting live traffic to the new environment without any customer-facing impact.
  • Auto-Scaling Implementation – Introduced load-based scaling to support fluctuating usage patterns, reducing risk of outages and supporting future growth.
Engineering Excellence
  • Code Oversight – Established a mandatory code review and pull request process, ensuring all upgrades aligned with compliance goals and prevented unnecessary or risky changes from being deployed.
  • Team Integration – Embedded directly in offshore team standups, actively monitoring and guiding their work to keep progress aligned with business priorities and technical requirements.
  • Issue Resolution – Rapidly identified and remediated problems caused by legacy code or unsupported libraries, minimizing technical risk and accelerating the upgrade timeline.

The Results

Built and Shipped

DevIQ’s intervention enabled the client to meet their regulatory deadline with zero downtime, preserve revenue from their most important contracts, and set a new baseline for operational reliability.

  • Continuous Service Delivery – No disruption to end users; contractual SLAs maintained.
  • Future-Proofed Platform – Legacy app stabilized on scalable, serverless infrastructure, supporting compliance and ongoing maintenance.
  • Operational Efficiency – Freed internal resources from high-risk legacy management, allowing renewed focus on innovation and core products.

By the Numbers

  • 100% Deadline Compliance – AWS TLS deadline met; no exceptions required.
  • Zero Downtime Migration – Customers experienced no interruptions during cutover.
  • Reduced Operational Overhead – Serverless migration likely lowered infrastructure costs, with auto-scaling matching resource use to demand.

The Conclusion

This childcare platform’s experience shows how, even under high-stakes regulatory pressure, an expert technical partner can deliver not only compliance – but improved reliability, efficiency, and business resilience. With DevIQ as a guide, the provider secured critical contracts, averted disruption, and set the stage for future modernization.

Looking ahead, the client is empowered to move faster, take on new transformation initiatives, and rely on DevIQ for targeted expertise whenever the stakes are high.
