In their own words
SingleStore Helios
SingleStore Helios is a cloud database service available on AWS, Google Cloud, and Microsoft Azure. It handles transactional and analytical workloads in one database, with storage and compute scaled independently. Its data capabilities include relational records, JSON/BSON documents, vector and full-text search, time-series, geospatial, and key-value data. SingleStore Pipelines can ingest from sources such as Kafka, Amazon S3, and HDFS. For AI workloads, the service includes Jupyter notebooks, data integration services, and a compute service. Listed integrations include Datadog, Terraform, Apache Spark, AWS Glue, Azure Data Factory, dbt, and Fivetran. Helios is available through web and API platforms. The free Shared plan provides one workspace for evaluation, development, and non-production testing, with self-support. Standard is $0.99 a month for managed production workloads, with read replicas, database branching, 30-day monitoring, and support. Enterprise is $1.49 a month and adds online point-in-time recovery, Smart Disaster Recovery, audit logging, and customer-managed encryption keys. The listed availability commitments vary by configuration, reaching 99.99% across two availability zones on paid plans.
Zilliz Cloud
Zilliz Cloud is a managed Milvus service for deploying and scaling vector search applications. It supports approximate nearest neighbor, filtered, hybrid, and full-text search. Teams can choose Free, Serverless, or Dedicated cluster deployments; Serverless clusters scale automatically to zero. During ingestion, the service can create vector embeddings from raw text using a configured embedding function.
Documented integrations include Prometheus, Datadog, AWS S3, Azure Blob Storage, Google Cloud Storage, and external model providers. Migration sources include Pinecone, Qdrant, Elasticsearch, and PostgreSQL. The service supports sparse vectors, metadata filtering, up to 32768 dimensions, and a range of index types, including FLAT, HNSW, DISKANN, and AUTOINDEX. SDKs are listed for Python, Java, Go, Node.js, and C++. The Free cluster costs nothing and includes 5 GB storage, 2.5M vCUs/month, and up to 5 collections. Dedicated and Serverless pricing is pay as you go; storage charges apply to stored data and backup files even when a cluster is stopped.
