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