AWS Unified Operations: Building Resilient Operations for Critical Workloads

Enterprises face three structural challenges in cloud operations: a shortage of specialized personnel, limited visibility, and the absence of a preventive system focused on reactive response. In particular, the hourly cost of a large-scale outage can reach $2 million, and a quarter of operational time is sometimes wasted filtering out false positives.

AWS Unified Operations aims for a shift-left paradigm that removes failure factors earlier in the application lifecycle, rather than responding after problems occur. It focuses on resolving structural weaknesses in operations through AI-driven insights and dedicated experts.

The key elements are as follows:

• Proactive Guidance: A dedicated team of experts, including TAMs and DSEs (Domain Specialist Engineers), provides context-aware support from planning through operations. This includes in-depth reviews at the design stage, real-time support at launch, and continuous optimization after launch.
• Rapid Incident Management: Shortens MTTI (Mean Time to Ingest) and MTTR (Mean Time to Resolve). By integrating with Amazon CloudWatch and third-party tools, it monitors around the clock and opens a call bridge within 5 minutes when a critical alarm occurs, enabling response 3 times faster than standard support.

Customized Runbooks, AI-driven incident analysis, and direct escalation to AWS backend service teams also help resolve complex issues quickly. In one real-world case, a customer processing 48 million contracts per day achieved a successful migration by optimizing Lambda concurrency with the help of dedicated experts.
