： AWS拥有覆盖全球的庞大基础设施。截至2026年，其云服务已覆盖 39个地理区域 中的 123个可用区 ，并计划新增更多区域。这种全球性布局使得企业可以轻松地将应用部署到靠近最终用户的地区，在任意规模下提供超低延迟的卓越体验。
AWS has rapidly evolved to become a major hub for Artificial Intelligence (AI) and Generative AI applications, offering tools that cater to developers, data scientists, and enterprise legal teams alike.
Edge Locations are endpoints used by AWS to cache content closer to end-users. They are primarily utilized by Amazon CloudFront (Content Delivery Network) and Amazon Route 53 (DNS service). By caching static media, videos, and APIs at the edge, AWS drastically reduces latency for global audiences. Foundational AWS Services Essential for understanding how to secure infrastructure and

AWS has become a leader in generative AI through services that simplify building and deploying models.
Each AWS Region consists of multiple, isolated, and physically separate Availability Zones (AZs). An AZ is composed of one or more discrete data centers equipped with independent power, cooling, and physical security. AZs are connected through ultra-low-latency, redundant fiber-optic networking. Architecting applications to run across multiple AZs ensures high availability and resilience against localized hardware failures. Edge Locations
A fully managed, serverless, NoSQL database that delivers single-digit millisecond performance at any scale. 3. Security and the Shared Responsibility Model
Data storage needs vary by access speed, volume, and structure. AWS splits this into object, block, and file systems.
is a MySQL and PostgreSQL-compatible relational database that provides the security, availability, and reliability of commercial databases at 1/10th the cost. Its cloud-native architecture separates compute and storage, allowing for significantly better performance and scalability. In a major 2025 case study, Netflix consolidated its relational database infrastructure onto Aurora, achieving up to 75% improved performance and a 28% cost reduction .
