Titanium

    Titanium is Google Cloud's custom-designed architecture that offloads networking and storage tasks to dedicated hardware, delivering more consistent and predictable performance by reserving the entire CPU exclusively for your application.

    Titanium, powered by Google

    Titanium underpins Google Cloud’s latest virtual machine types, including C3, C3D, C4, C4A, C4D, H3, H4D, N4D, N4A (preview), X4, and Z3. Hyperdisk block storage and networking are also available.

    The system includes:

    • Titan security microcontrollers: Custom-designed to provide a hardware root of trust for Google Cloud's infrastructure
    • Titanium adapter: Dedicated offload card that provides hardware acceleration for virtualization services; this offloads processing from the host CPU, freeing up resources for your workloads
    • Titanium SSD: Custom-designed Local SSD based on Titanium I/O offload processing to enhance SSD security, performance, and management
    • Titanium offload processors (TOPs):  A scalable and flexible way to offload network and I/O processing from the host CPU onto silicon devices deployed throughout the data center

    Improved infrastructure performance

    Titanium delivers more compute and memory resources for your workloads by offloading processing from the host hardware.

    • Up to 500k IOPS per instance with Hyperdisk Extreme block storage; the highest among leading hyperscalers 
    • Up to 200 Gbps of network bandwidth
    • Network encryption at full line rate, providing security without sacrificing performance
    • Bare-metal-like consistent performance for the most sensitive workloads

    Infrastructure security rooted in hardware

    Titanium protects your workloads from security threats by offloading security processing from the host hardware.

    • Titan security microcontrollers ensure systems boot from a known, trusted state
    • Provide a root of trust for secure data center communication

    Seamless infrastructure life cycle management

    The modular software and hardware of Titanium, coupled with offloading functionality, facilitates infrastructure updates while maintaining workload continuity and security. 

    • Seamless updates for majority of workloads and advanced maintenance controls for the most sensitive workloads
    • Remote infrastructure updates can be initiated from anywhere
    • Networking and storage functions are all executed off host in dedicated domains of the Titanium adapter, allowing independent updates and maintenance of each service, isolated from workloads on the host
