Zilliz Cloud offers three types of Compute Units (CUs) - Performance-optimized, Capacity-optimized, and Cost-optimized. The Performance-optimized CU is ideal for rapid response time applications with high throughput requirements such as Generative AI, Recommender systems, Search engines, Chatbots, Content moderation, Augmenting LLMs' knowledge base, and Anti-fraud systems. Capacity-optimized CUs are suitable for handling large-scale unstructured data searches like text, images, videos, and molecular structures, copyright violations detection, and identity verification. Cost-optimized CUs are perfect for offline tasks with a tight budget but higher search latency. The performance comparison shows that the Performance-optimized CU outperforms others in terms of latency and throughput. Capacity evaluation results indicate that capacity-optimized and cost-optimized CUs have equal capacities, five times larger than the performance-optimized CU. Examples are provided to help businesses choose the most suitable option for their needs.
