A software company wants to deliver its application globally with low latency. Which Azure service best achieves this?

Azure Content Delivery Network (CDN) is the best choice because it caches static content at edge locations worldwide, close to users. This significantly reduces latency by serving content from the nearest point of presence. Availability Zones enhance high availability within a single Azure region, not global low latency. Resource Groups are logical containers for Azure resources and do not directly impact performance. Azure Security Center provides unified security management and threat protection, unrelated to content delivery performance.
