As enterprises advance in cloud-native and digital transformation, AWS Development—AWS application development and delivery—has evolved beyond “writing code and deploying applications.” It has become a systematic engineering discipline involving architecture design, cost management, security compliance, and continuous operations.

With the rapid adoption of large language models (LLMs), generative AI, and Retrieval-Augmented Generation (RAG), vector databases have become a foundational component of modern AI application architectures. Whether for intelligent Q&A systems, semantic search, AI agents, or multimodal retrieval, efficient storage and similarity search of vector embeddings are essential.

As containerization technologies become increasingly popular in enterprises, how to run and manage container workloads in a stable and efficient manner has become a key challenge in cloud architecture design. Amazon Elastic Container Service (AWS ECS), a fully managed container orchestration service provided by AWS, is now widely adopted by enterprises to host mission-critical business systems.

As a leader in the Global cloud computing field, Amazon Web Services (AWS) has built the currently largest, most mature and most secure cloud computing Infrastructure system in the world - AWS Global Infrastructure. This vast network is composed of high-standard data centers distributed all over the world. Through precise design and reliable interconnection, it provides millions of users globally with consistent high availability, high performance and low latency experiences.

In modern application development, user authentication and access control are indispensable basic capabilities. In order to relieve the development team from being preoccupied with building the back-end system for account systems, login logic, data synchronization and permission management, Amazon Web Services (AWS) has launched Amazon Cognito - a secure, consistent and scalable user identity and access management service specifically designed for mobile and Web applications.
