29
Which AWS Service is for Telecom Providers
AWS Wavelength Zones are a type of AWS infrastructure that brings compute and storage services to the edge of 5G networks, enabling low-latency applications. Here "edge" of 5G networks refers to the network infrastructure closest to end-users and devices, where data is generated and processed.
30
AWS services are deployed in the city to deliver low-latency experiences , with the ability to deliver single-digit millisecond latency for users .
AWS Local Zones - An extension of an AWS Region in geographic proximity to your users, where the Local Zone infrastructure is deployed. These zones are often situated in large metropolitan areas and provide a selection of AWS services, including EC2, RDS,and EKS. By deploying resources in a Local Zone, customers can reduce latency for end-users in that location, improving application performance and responsiveness.
31
How does ELB scales EC2 instances ?
By using auto-scaling groups
