IRS business systems that collect and process taxes, detect fraudulent activity, and provide customer service to millions of users, rely on an underlying infrastructure to provide an environment to execute these functions. The IRS infrastructure also provides business applications with services to transmit, protect, process, and store data, along with services to integrate those business applications with one another. This is why the IRS uses all means available to keep the infrastructure up and running 24×7, 365 days a year.
The IRS infrastructure is comprised of numerous COTS and custom subsystems. These systems require routine inspection, monitoring, tuning, patching and other operation and maintenance activities. The IRS takes on these enormous challenges using an organization of dedicated and skilled civil servants with years of experience keeping systems up and running. Even with the IRS’s strong support staff, gaps in required expertise affect their ability to deliver a reliable environment.
