Multicloud AI & ERP / Cloud Migration, Integration & AI Operations
Why it matters
An application built from several services inherits their combined risk. Without redundancy, three services at 99.9% each give noticeably less than 99.9% together. Knowing this shapes design and support choices.
How it works
From SLAs to design
Read the SLAs for each service and configuration. Calculate the composite SLA by multiplying the services in the request path. Add redundancy across zones or regions to close the gap, subscribe to health alerts and choose a support plan whose response times match the risk.
AWS, Azure and Google Cloud compared
| AWS | Azure | Google Cloud | |
|---|---|---|---|
| Service health | AWS Health Dashboard | Azure Service Health | Personalized Service Health |
| Resource health | AWS Health events | Resource Health | Service Health API |
| Best-practice checks | Trusted Advisor | Azure Advisor | Recommender |
| Support plans | Business, Enterprise On-Ramp, Enterprise | Standard, Professional Direct, Unified | Standard, Enhanced, Premium |
| Automation on events | EventBridge health events | Service Health alerts with action groups | Alerts in Cloud Monitoring |
What makes each cloud different
AWS
The AWS Health Dashboard shows events affecting your accounts, with an organizational view across all accounts, and health events can trigger EventBridge automation. Trusted Advisor checks limits, cost and security.
Azure
Azure Service Health reports incidents and planned maintenance relevant to you, Resource Health shows the state of each resource and Azure Advisor gives reliability recommendations.
Google Cloud
Personalized Service Health shows incidents affecting your projects and feeds them into your tools through an API, and regional resources often carry higher SLAs than zonal ones.
Design decisions that matter
- 01Calculate composite SLAs
For every critical user journey.
- 02Design redundancy for the gaps
Zones first, regions where justified.
- 03Health alerts to on-call
Know before customers tell you.
- 04Support matched to risk
Response times for critical systems.
Common mistakes we see
- Assuming the cloud is always up. Every service has documented downtime.
- Learning about incidents from social media. Hours lost.
- Basic support for critical systems. Slow help when it matters most.
