SeaGaruda

I am an engineer working on industrial software and cloud infrastructure: metering platforms, SCADA integration, energy data pipelines, and the unglamorous work of moving them onto public cloud without breaking them.

This blog collects what actually held up in delivery — not vendor summaries. Every article is written after the code, the migration, or the outage.

What you will find here

• Cloud migration — what changes when bare-metal assumptions meet elastic infrastructure, especially inside database code.
• Architecture — when load balancing is enough and microservices are premature; how to size a monolith-to-distributed move honestly.
• Databases — managed MySQL/PostgreSQL in practice, time-series workloads, and the parameters nobody warns you about.
• OT security — the Purdue Model read as a logical data-flow contract rather than a floor plan.
• Digitalization — why systems go live and processes stay in WeChat groups and Excel.
