    Managed vector search has reduced infrastructure overhead and empowers faster AI workloads

    Reviewed on Jun 02, 2026
    Review from a verified AWS customer

    What is our primary use case?

    I am primarily using Zilliz Cloud for a managed vector database, storage, and searching and indexing.

    My primary workload involves storing and searching high-dimensional vector embeddings that are generated from documents and all the knowledge bases that I have, along with all the technical contents and the application data that I have. This platform is a core component of my RAG system architecture. Prior to adopting this managed vector database, I also tried self-hosted Milvus, which is not very scalable and has very high setup overhead, and so we decided to use Zilliz Cloud.

    What is most valuable?

    Zilliz Cloud has allowed us to focus on building the AI products without the overhead of operating vector database infrastructure.

    The best features Zilliz Cloud offers, in my opinion, include high-performance similarity search, managed infrastructure for cluster maintaining, infrastructure scaling, backup management, storage planning, Milvus compatibility, and metadata filtering.

    The offering of this managed infrastructure of a vector database is most useful for me, and the high-performance similarity search is useful in my case.

    Regarding the similarity search, it delivers low latency retrieval and maintains strong relevance in returned units, which is particularly useful for me.

    Zilliz Cloud has positively impacted my organization because initially, we spent too much time hosting self-hosted Milvus and planning for infrastructure that did not yield very useful results. Now, we do not have the overhead of managing infrastructure for my vector database, so we can directly focus on building our RAG system and AI workload.

    Time saved is the first and foremost outcome since all the time we invested in self-hosting Milvus has been redirected towards building the AI workloads. Time has definitely been saved, which is the primary benefit of using Zilliz Cloud.

    What needs improvement?

    It can be improved a little bit on the search functionality.

    Not in specific search functionality, but I would like to see more visibility in the costing part and the monitoring dashboard.

    Zilliz Cloud could provide more automated optimization guidance, particularly for large-scale deployments, mostly around index selection, partitioning, and resource sizing, which would help maximize performance.

    For how long have I used the solution?

    I have been using Zilliz Cloud for the past one year.

    What other advice do I have?

    If you are building some AI workloads, do not focus on managing the vector database. It is an operational overhead. Start building the AI workload instead. I would rate this product a 9 out of 10.

    Which deployment model are you using for this solution?

    Public Cloud

    Managed vector search has reduced latency and now accelerates CNN-based RAG workflows

    Reviewed on May 18, 2026
    Review from a verified AWS customer

    What is our primary use case?

    I have Milvus hosted on Zilliz Cloud and am majorly using it to manage the vector database and utilizing some of the RAG and vector features from that.

    I connected Zilliz Cloud with a lot of Kubernetes clusters on Zilliz Cloud to fetch a lot of data because we have a client who wants to use CNN models to give the best result from their database. We have RAG, which is using vector embedding, and we manage everything on AWS, where some of the services are connected with Zilliz Cloud to gather everything faster.

    What is most valuable?

    The best feature of Zilliz Cloud is that it helps in very high-performance vector search, and it is also very scalable, with very low latency that helps provide faster results. The deployment of Milvus is very easy because it is managed there, so I did not need to take care of anything. These are the major things that I feel are very important.

    Zilliz Cloud has positively impacted my organization because previously, when I was not using it, there was a little lag in the output of the search due to the lack of a proper vector search setup, and maintaining the vector search was very hard, requiring me to create a model, deploy it, and connect everything. It helped me a lot by using managed Milvus, which simplifies my management tasks.

    What needs improvement?

    Having more connections with all other major clouds could be helpful, and a marketplace could grow with Zilliz Cloud.

    For how long have I used the solution?

    I have been using Zilliz Cloud for around seven to eight months.

    What do I think about the stability of the solution?

    Zilliz Cloud is stable in my experience.

    What do I think about the scalability of the solution?

    Its scalability is very good.

    How are customer service and support?

    The customer support is also good.

    Which solution did I use previously and why did I switch?

    I have not used any different solutions before Zilliz Cloud.

    What was our ROI?

    The biggest return on investment I have seen is in the time saved in my current scenario.

    What's my experience with pricing, setup cost, and licensing?

    The pricing, setup cost, and licensing experience were pretty straightforward, and although I was not involved with the team, I felt it was smooth.

    Which other solutions did I evaluate?

    Before choosing Zilliz Cloud, I evaluated Weaviate and PineconeDB.

    What other advice do I have?

    If others do not have the bandwidth to manage the vector search and maintain that on the cloud, I recommend that they find it very easy to use Zilliz Cloud.

    Zilliz Cloud is deployed in my organization on a public cloud.

    I use AWS as my cloud provider.

    I did not purchase Zilliz Cloud through the AWS Marketplace; the company directly purchased it.

    Zilliz Cloud helps a lot, and I also contribute to the community while creating a lot of awareness for people to use it. I would rate this review an overall eight out of ten.

    Which deployment model are you using for this solution?

    Public Cloud

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Amazon Web Services (AWS)
