Migrate legacy monoliths to AWS serverless by mapping domains, extracting APIs, moving data safely, and deploying iteratively with Lambda, API Gateway, and observability.
Top API pentest tools in 2026 pair OpenAPI-aware scanning, auth testing, fuzzing, and CI/CD integration to find exploitable flaws before attackers do.
Implement OAuth 2.0 safely: use Authorization Code with PKCE, keep secrets server-side, rotate credentials, and never embed client secrets in mobile, SPA, or public code.
Resolve CORS in complex SPAs by aligning API origins, preflight headers, credentials, and proxy rules-then log OPTIONS failures to pinpoint misconfigured gateways.
Optimize globally: Place read replicas near users, route reads by latency, and monitor replication lag. Tune indexes and connection pools to keep apps fast and resilient.
Automated rollbacks pair health checks, deployment gates, and versioned releases to detect failures early and restore the last stable build without manual intervention.
Backward-compatible REST APIs preserve contracts: add optional fields, avoid changing meanings, version only for breaking changes, and document deprecations with clear timelines.
Cut GitHub Actions build times by caching dependencies, splitting jobs in parallel, using path filters, right-sized runners, and uploading only essential artifacts.
Pod evictions in high-traffic clusters often stem from memory pressure, disk pressure, or QoS misalignment. Start with node events, resource requests, and eviction thresholds.
Reduce latency by profiling service calls, caching hot data, tuning timeouts, and replacing chatty sync APIs with batched, async messaging where possible.
