The Department of Veterans Affairs (VA) prioritizes maintaining accessible, reliable, and secure digital services to provide quality care and benefits to veterans, their families, and caregivers across the United States. As the largest integrated healthcare system and benefits provider in the country, the VA faces the challenge of managing 2.7 million pieces of equipment and supporting millions of users on its digital platforms. The passage of the PACT Act in 2022, which expanded eligibility for healthcare and benefits, significantly increased demand on the VA's digital systems, prompting the agency to quickly scale its infrastructure. To address this, the VA implemented Datadog’s observability platform for real-time monitoring and optimization, ensuring system reliability and performance while complying with FedRAMP® security standards. This strategy allowed the VA to maintain a high level of service continuity, crucial for healthcare operations where even minor disruptions can have significant impacts. The VA's commitment to modernization and observability reflects its dedication to operational excellence and resilience, ensuring veterans receive the care and benefits they deserve.
