Zilliz

Cloud-based vector database service for enterprises

Overview

Zilliz provides a cloud-based vector database service that helps enterprises run vector search applications at scale. Its main product, Zilliz Cloud, is a fully-managed platform that handles deployment, scaling, and operation of vector databases, so customers do not have to build or maintain infrastructure. It supports large-scale vector data (up to 500 compute units and tens of billions of items) and is designed to work with diverse tech stacks. The company differentiates itself by offering a high-performance, reliable service with strong security (SOC 2 compliance and 99.9% uptime) and a focus on customer experience, while planning to add features like Role-Based Access Control. Its goal is to enable businesses to deploy and scale vector similarity search easily and securely, freeing them to focus on their core operations.

Simplify's Take

What believers are saying

  • Over 10,000 enterprises like Nvidia and Walmart use Zilliz for RAG and semantic search.
  • BYOC on AWS, GCP, and Azure enables data sovereignty without self-hosting overhead.
  • Cross-region disaster recovery achieves sub-60-second failover across all major clouds.

What critics are saying

  • Pinecone's serverless pricing undercuts Zilliz Cloud, causing mid-market churn by 2027.
  • AWS OpenSearch vector search erodes Zilliz adoption among AWS customers in 6-12 months.
  • Enterprises self-host Milvus via Kubernetes, bypassing Zilliz Cloud revenue in 12-24 months.

Zilliz Cloud adds native cross-region disaster recovery with sub-60-second failover for vector databases

Zilliz, the company behind the Milvus open-source vector database, has launched native cross-region disaster recovery for Zilliz Cloud, offering automated failover with sub-60-second recovery times and near-zero data loss. The new capabilities include Global Cluster, which enables real-time replication between regions with automatic failover; Global Endpoint, which automatically reroutes traffic without code changes; and Cross-Region Backup for cost-effective disaster recovery. The features address critical infrastructure resilience gaps exposed by recent cloud outages that cost Fortune 500 companies billions. Vector databases power enterprise AI workloads including RAG pipelines and semantic search, but rebuilding vector indexes can take over 18 hours. The disaster recovery capabilities are now available on Zilliz Cloud across AWS, GCP and Azure. Over 10,000 organisations worldwide use Zilliz's platform.

Zilliz Cloud launches native Cross-Region Disaster Recovery for vector databases.

Zilliz Cloud launches native Cross-Region Disaster Recovery for vector databases. PR Newswire Today at 4:00am PDT New Global Cluster and Global Endpoint capabilities deliver automated failover with near-zero downtime for enterprise AI applications REDWOOD CITY, Calif., March 27, 2026 /PRNewswire/ - Zilliz, the company behind Milvus, the world's most widely adopted open-source vector database, today announced native cross-region disaster recovery for Zilliz Cloud, making it the only vector database to offer automated cross-region failover with near-zero data loss and sub-60-second recovery times. Recent high-profile cloud outages - including simultaneous AWS region failures in the Middle East, a 14.5-hour Azure outage, and cascading infrastructure incidents costing Fortune 500 companies billions - have exposed a critical gap in AI infrastructure resilience. With nearly 60% of employees now relying on AI-powered workflows daily, region-level failures no longer cause gradual slowdowns; they trigger immediate productivity cliffs across the enterprise. "Cloud regions will fail - that's not a prediction, it's an operational certainty. What matters is whether your AI infrastructure can recover in seconds rather than hours. We built cross-region disaster recovery natively into Zilliz Cloud so that enterprises never have to choose between the performance of vector search and the resilience their applications demand." said Charles Xie, Founder and CEO at Zilliz. Why Cross-Region Disaster Recovery Matters for AI Vector databases power critical enterprise AI workloads - from RAG pipelines and semantic search to recommendation engines and AI agents. Unlike stateless model inference, vector indexes containing hundreds of millions of vectors can take 18+ hours to rebuild, making traditional disaster recovery approaches impractical. Zilliz Cloud's new capabilities address this with three complementary solutions: * Global Cluster: Real-time Change Data Capture (CDC) replication between primary and secondary clusters in different regions enables planned switchovers with zero data loss and automatic failover in under 60 seconds. * Global Endpoint: A single connection endpoint with SRV DNS-based routing automatically reroutes application traffic during failover - requiring no code changes, connection string updates, or application restarts. * Cross-Region Backup: Cost-effective backup replication to target regions with configurable retention policies, enabling recovery from any backup point for workloads where data durability is the priority. Beyond disaster recovery, Global Cluster also enables latency optimization by placing replicas closer to end users, zero-downtime region migrations, and compliance with geographic data residency requirements. Now Available Cross-region disaster recovery capabilities are now available on Zilliz Cloud dedicated clusters across AWS, GCP, and Azure. Existing customers can activate Global Cluster and Global Endpoint from the Zilliz Cloud console. New users can create a free account with $100 in credits to get started.

Zilliz Cloud launches customer-managed encryption keys for enterprise AI data sovereignty

Zilliz, the company behind open-source vector database Milvus, has launched Customer-Managed Encryption Keys (CMEK) on Zilliz Cloud, enabling enterprises to maintain full control over encryption keys for AI workloads in regulated industries. The capability allows organisations to retain exclusive ownership of encryption keys, addressing regulatory requirements under GDPR, HIPAA, PCI-DSS and SOC 2. Zilliz processes data whilst customers control encryption keys through AWS KMS, creating separation required by compliance teams. Disabling a key immediately renders cluster data cryptographically inaccessible, with all access events logged in AWS CloudTrail. CMEK is available for Dedicated clusters on Zilliz Cloud's Business-Critical plan, starting with AWS. Over 10,000 organisations worldwide use Zilliz's platform for vector search and hybrid retrieval workloads.

Zilliz open-sources Memsearch, giving AI agents persistent, human-readable memory

Zilliz has open-sourced memsearch, a library that provides AI agents with persistent, human-readable memory across conversations. Released under the MIT licence, memsearch was extracted from OpenClaw's memory system and stores all agent memories as plain-text files that developers can read, edit and version-control. The library addresses a key limitation in AI agents, which typically forget context when conversations end. Unlike proprietary solutions, memsearch stores memories as standard files indexed by the Milvus vector database, enabling semantic retrieval whilst maintaining full transparency and portability. Zilliz has also released a dedicated plugin for Claude Code, Anthropic's AI-powered coding assistant, which automatically captures and injects session context. The company, backed by Aramco's Prosperity 7 Ventures and Temasek's Pavilion Capital, serves over 10,000 organisations worldwide.

Zilliz Cloud launches BYOC on Azure, first managed vector database across all three major clouds

Zilliz, the company behind the Milvus vector database, has launched its Bring Your Own Cloud (BYOC) service on Microsoft Azure, becoming the first managed vector database provider to support BYOC across all three major cloud platforms—AWS, Google Cloud Platform and Azure. BYOC deploys a fully managed vector database directly inside a customer's cloud account, allowing organisations to maintain data control whilst avoiding the engineering burden of self-hosted deployments. The Azure launch enables enterprises to run their vector database alongside Azure OpenAI Service within a single cloud environment, eliminating cross-cloud data movement. The service is now available across all three platforms, with deployment supporting billion-scale workloads. Over 10,000 organisations worldwide use Zilliz's platform.
