Cloud deployment for Large Language Models (LLMs) offers several benefits including scalability, cost efficiency, and accessibility, but also poses security concerns and dependence on internet connectivity. On-premises deployment, in contrast, provides control and customization, security, and performance advantages, but comes with significant upfront costs and scalability limitations. Organizations should carefully evaluate their needs, considering factors such as cost analysis, scalability requirements, security demands, performance needs, and maintenance support before making an informed decision between cloud and on-premises deployment options for LLMs.
