Real-world perspectives on infrastructure, scalability, and what actually works when you're building systems that need to stay online.
We moved a client from single-zone to multi-zone last quarter, and honestly? The database replication nearly killed us. Here's what the documentation doesn't tell you about latency patterns across Taiwan's availability zones.
Most cloud content reads like vendor documentation. We try to share what actually happens when you deploy these systems in production.
Real latency numbers from regional deployments. We track response times across different zones and share what works for Taiwan-based infrastructure.
The weird errors that cost us hours. Database connection pooling issues, memory leaks in containerized apps, and other fun surprises.
Where money disappears in cloud billing. Storage transfer costs between regions, compute instances that run 24/7 when they shouldn't, and reservation strategies.
Configuration mistakes we've seen repeatedly. IAM policies that grant too much access, unencrypted data stores, and network rules that expose internal services.
Metrics that actually matter during incidents. CPU graphs don't help much when your application is failing for reasons that won't show up in standard dashboards.
Moving from on-premise infrastructure to cloud platforms. Data migration strategies, downtime windows, and handling the unexpected compatibility issues.
