Cloud Storage Rapid is our response to the generational shift in how organizations build with AI. Teams are training trillion-parameter models, deploying inference at global scale, and building autonomous agents that reason over vast amounts of enterprise data. While accelerators like GPUs and TPUs often get the spotlight, they have a critical dependency: storage.
Storage is the engine that feeds accelerators during training, and the fast-access layer that makes real-time inference responsive. But as models scale, storage performance can be a bottleneck. Every time an AI/ML cluster waits on a data read or a checkpoint write stalls, you are paying for expensive compute cycles that aren’t doing useful work.
Historically, AI/ML practitioners have had to choose between the specialized performance of a niche, zonal storage system, and the reliability and scale of a global object store like Google Cloud Storage. Many developers value Cloud Storage for its simplicity, scalability, reliability, and cost-effectiveness, but as the AI era has progressed, they’ve been throwing hotter and hotter workloads at it, running training and inference workloads with thousands of GPUs and TPUs. We’ve reached a performance tipping point that traditional object storage was never meant to handle. The Rapid family provides multiple options for co-locating compute workloads directly with high-performance zonal storage. It minimizes I/O bottlenecks that can block accelerators, so that your GPUs and TPUs stay fully saturated and productive. In this blog, let’s take a closer look at Cloud Storage Rapid’s capabilities.
Rapid Bucket
Rapid Bucket (GA), helps Cloud Storage meet the evolving demands of massive-scale generative AI, analytics, and other high-performance workloads. It does so by leveraging Colossus, the Google distributed storage system that powers Gemini and YouTube, to provide massive read/write performance and ultra-low latency in a dedicated object storage zonal bucket.
Lightning-fast performance
By combining the sub-millisecond latency of block-like storage, the throughput of a parallel filesystem, and the scalability and ease of use of object storage, Rapid Bucket provides high performance from the same Cloud Storage that you know and love.
Highlights include:
-
Ultra-low latency: Achieve up to 20 million queries per second and sub-millisecond latency.
-
Massive scalability: Rapid Bucket delivers 15+ TB/s of aggregate read throughput from a single Rapid zonal bucket.
-
New semantics: Enable higher performance with new capabilities such as native appends, unlimited readers (while writing!), and vectored reads.
Optimized for AI and analytics
You can use Rapid Bucket for a variety of demanding scenarios, including AI/ML data preparation, training, checkpointing, batch and streaming analytics processing, and optimizing distributed database architectures.
Key benefits include:
-
Optimized accelerator utilization: With Rapid Bucket, we observed 50% reduced blocked GPU time and up to 2.5x faster data loading for multi-modal training runs.
-
Faster checkpointing: Rapid Bucket makes checkpoint restores up to 5x faster and writes 3.2x faster compared to traditional object storage. This ensures faster recovery from workload interruptions, minimizes wasted accelerator time, and increases overall efficiency.
