Dr. Werner Vogels, keynote speaker at re:Invent 2023, discusses the philosophy of building systems, the impact of AI, and new AWS features including zonal auto shift, Amazon CloudWatch application signals, My Applications capability, IDE extension for AWS application composer, integration of ISE templates, and efficiency and cost optimization in Amazon SageMaker.
AWS Fault Injection Service (FIS) allows users to simulate power interruptions or lost connectivity between AWS regions to test application resilience and recovery capabilities.
Amazon CloudWatch Application Signals provides automatic instrumentation of applications, standardized dashboards, and SLOs to troubleshoot and reduce disruptions.
Deep dives
Availability and Resilience Testing with AWS Fault Injection Service (FIS)
The AWS Fault Injection Service (FIS) now allows users to demonstrate multi-region and multi-AZ application resilience. Through new scenarios, customers can simulate power interruptions or lost connectivity between AWS regions to test their applications' performance and recovery capabilities. The scenarios help build confidence in the application's ability to handle failures, identify dependencies, and test recovery time. The results can also be utilized for compliance processes in specific industries. FIS is available at no additional cost in all commercial AWS regions.
Zonal Auto Shift with Amazon Route 53 Application Recovery Controller
Amazon Route 53 Application Recovery Controller now offers a new feature called Zonal Auto Shift. This capability automatically and safely shifts your workload traffic away from an availability zone when AWS detects a potential failure. By deploying resilient applications across multiple availability zones, users can protect their applications' availability and investigate the root cause of a failure. Once resolved, traffic can be shifted back to the affected availability zone, ensuring continuous service availability. Zonal Auto Shift is available at no additional cost in all AWS regions, except for China and GovCloud.
Improved Observability with Amazon CloudWatch Application Signals
Amazon CloudWatch Application Signals presents a new capability, allowing for the automatic instrumentation of applications based on best practices. This solution assists in monitoring big distributed systems by providing prebuilt, standardized dashboards with key metrics such as request volume, latency, and availability. Users can define service level objectives (SLOs) specific to their business needs, correlating metrics, traces, logs, and monitoring data. This integration helps with troubleshooting, reducing disruptions, and promoting collaboration within teams. Amazon CloudWatch Application Signals is available in preview in select AWS regions.
