The integration of Pinecone with Pulumi provides a streamlined method for managing Pinecone indexes, including the newly introduced serverless indexes, through any of Pulumi's supported programming languages. This integration applies Infrastructure as Code principles, enhancing efficiency and offering access to Pulumi's extensive array of providers for enriched development capabilities. Pinecone is a managed vector database, essential for AI applications such as large language models and semantic search, due to its ability to handle vector embeddings with low latency for billions of vectors. The introduction of a serverless vector database by Pinecone allows for scalable and cost-effective deployment of AI applications, facilitated by a "pay for what you use" pricing model. The Pinecone Provider for Pulumi simplifies the process of creating, updating, and deleting indexes, while also enabling the use of custom provider configurations for deploying indexes across multiple accounts. This integration empowers developers to maintain reproducible infrastructure as code for AI applications utilizing Pinecone indexes.
