HACA's Cloud Transformation: Ensuring Resilience and Public Service Success with Azure & 365

The Housing Authority of the City of Austin (HACA) has long served as a lifeline for low-income families, providing stable housing and crucial public services in a climate beset by both economic and environmental uncertainties. For organizations with such a vital mission, technology’s reliability is not simply a matter of efficiency—it is a fundamental pillar of public trust and operational continuity. In this era of ever-increasing cyber risks and climate volatility, HACA’s recent full-scale migration to Microsoft Azure and Microsoft 365, expertly orchestrated by Rackspace Technology, stands as a testament to the transformative power of cloud computing done right.

The Urgency of Modernization: Lessons from a Crisis​

In early 2021, a catastrophic winter storm swept Texas, crippling infrastructure well beyond the state’s signature energy grid. For HACA, the event was even more personal and consequential. Severe and prolonged downtime exposed the vulnerabilities of its legacy, on-premises technology systems and highlighted how traditional open-source infrastructure, while flexible and cost-effective under normal circumstances, falls short in true disaster scenarios. The downtime wasn’t just an IT headache—it put at risk the authority’s ability to communicate with residents, manage essential services, and deliver aid to those who needed it most.
According to Jorge Vazquez, HACA's Director of Technology Management and Innovation, technology downtime erodes the very foundation upon which public service agencies are built: “Our mission relies on technology being available 99.9% of the time.” This lived experience catalyzed an aggressive search for a solution that could guarantee resilience, continuity, and above all, secure, always-on access for both staff and the community.

Choosing the Future: The Move to Microsoft Azure and 365​

Following the crisis, HACA needed more than incremental upgrades; it required a digital overhaul—one engineered for resilience, rapid disaster recovery, and seamless, secure collaboration regardless of where staff or residents happened to be. The path forward took shape in a bold partnership with Rackspace Technology, a recognized leader in end-to-end hybrid cloud solutions.
The strategic decision to move HACA’s entire workload to Microsoft’s Azure and 365 cloud ecosystem wasn’t a mere tech refresh. It entailed:

• Transitioning 373 users from local, desktop-dependent workflows to interconnected, cloud-first productivity.
• Migrating over 3.7 terabytes of data—documents, emails, application data, and more—with zero loss and minimal Business Day disruption.
• Re-architecting disaster recovery strategies around cloud-native services, enabling rapid failover and data restoration from anywhere.
• Implementing stringent cybersecurity protocols baked into Azure’s architecture, leveraging continuous compliance monitoring and threat prevention.

Rackspace provided the expertise and oversight required for such a high-stakes project in the public sector, ensuring not just a successful technical migration, but also comprehensive change management, user onboarding, and post-migration support.

Key Technical Outcomes: Business Continuity Redefined​

When disaster struck in 2021, business continuity was measured in hours and days of unavoidable outage. Post-migration, HACA’s continuity metrics are fundamentally transformed:

• Uptime SLA: Microsoft Azure’s global infrastructure and distributed architecture make the 99.9% uptime goal realistic and sustainable, a leap forward from the limits of single-site, on-premises systems.
• Disaster Recovery: Automated backups, geo-redundant data storage, and rapid failover shorten recovery times from days to mere hours or minutes.
• Security: Real-time threat monitoring, automated patch deployment, and multifactor authentication harden HACA’s technology perimeter and internal networks.
• Agility: The agency can now integrate new technologies—AI-driven analytics, modern CRM systems, or online resident support portals—without the prolonged procurement and integration cycles that previously hampered innovation.

Rackspace Technology’s Role: Beyond the Technical​

While cloud migrations aren’t new, their success in highly regulated, mission-critical public sector settings hinges on both expertise and empathy. Rackspace’s role extended beyond virtual machines and data transfer scripts. Their Government Services division, led by Jeff Martinez, understood the stakes: “By modernizing HACA's technology stack, we've provided them with a flexible and secure foundation ready for emerging technologies, enabling quick adoption of advanced solutions and compliance with evolving standards.”
Migrating more than 3.7TB of diverse data—structured and unstructured—posed significant logistical and security challenges. Rackspace deployed a phased migration strategy, which included:

• Rigorous pre-migration auditing to identify data dependencies and potential compatibility issues.
• User training tailored to both technical staff and non-technical frontline workers, ensuring a smooth transition and minimum operational downtime.
• Post-migration support, with continuous performance monitoring and immediate escalation of any transition-related issues.

Rackspace’s ongoing partnership means HACA isn’t simply left to navigate tomorrow’s technological unknowns alone. Continued managed services provide access to subject matter experts, ensuring HACA’s systems remain modern, compliant, and secure as regulatory and threat landscapes evolve.

Benefits Realized: Measuring Success in Human Terms​

For many public sector technology leaders, “success” is measured in metrics: system uptime, recovery point objectives, percentage of users authenticated via multi-factor credentials. At HACA, these improvements translate directly into the agency’s ability to serve its core mission:

• Housing applications, emergency rental assistance, and maintenance work orders are now processed securely, even during regional disruptions.
• Staff collaboration, both on-site and remote, benefits from always-on cloud productivity tools, reducing bottlenecks and improving response times.
• The potential for direct digital services to residents—secure online portals for communication, document submission, and status tracking—will let the agency serve constituents with greater speed and transparency.

These are tangible advances, rooted in technology but realized in lives improved.

Critical Analysis: Strengths and Strategic Risks​

Strengths​

1. Resilience and Continuity​

Migrating to Azure and Microsoft 365 fundamentally elevates HACA’s ability to deliver on its public mandate, rain or shine. The global reach, automated failover, and built-in backup features are robustly documented by Microsoft and validated by countless public sector deployments worldwide.

2. Enhanced Security Posture​

Cloud security, particularly in Azure’s Government Cloud, benefits from a shared responsibility model, advanced AI-driven threat detection, and regular external audits. Coupled with regular updates and policy-based access controls, the risk of successful cyberattacks drops substantially, a fact widely recognized in public sector case studies.
