Cloud Infrastructure Support for Tax and Payment Systems

This is an ongoing support and maintenance contract for HMRC's CloudOS infrastructure that powers critical payment processing systems. The contract requires tiered support services (basic and advanced levels) for cloud-based servers and operating systems, including 24/7 incident response, routine security patching, system monitoring, and backup/disaster recovery capabilities. The successful supplier will ensure these essential systems remain operational and secure, enabling uninterrupted processing of citizen tax payments, National Insurance and PAYE processing, and benefit payments. Suppliers should have expertise in cloud infrastructure management, strong incident response capabilities, and experience supporting mission-critical government systems.
