Long-form posts on cloud and data platform migrations, architecture, FinOps, and platform engineering.https://replatform.in/enhttps://replatform.in/blog/13-why-watchdog-isnt-deflecting-pages/https://replatform.in/blog/13-why-watchdog-isnt-deflecting-pages/Datadog Watchdog's anomaly detection fires on statistical outliers in your metric streams. When 30-60% of your resources are untagged and your service map is stale, Watchdog learns the noise and perpetuates it. Here is what to fix before touching a single threshold.Wed, 24 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/14-aiops-readiness-7-checks/https://replatform.in/blog/14-aiops-readiness-7-checks/Seven dimensions to score before you deploy an AIOps tool — telemetry coverage, tag hygiene, alert signal-to-noise, runbook maturity, on-call ownership clarity, incident loop closure, and vendor fit. Score yourself before a vendor does.Wed, 24 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/15-the-real-prerequisite-for-aiops/https://replatform.in/blog/15-the-real-prerequisite-for-aiops/Most vendor readiness assessments for AIOps point at licensing gaps and product modules. The actual blocker is an observability foundation problem — tag hygiene, ownership mapping, telemetry coverage — that no amount of licensing fixes.Wed, 24 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/09-reserved-instance-coverage-by-family/https://replatform.in/blog/09-reserved-instance-coverage-by-family/AWS Cost Explorer's aggregate RI coverage metric rolls up all instance families into one number — which means burstable T3/T4g workloads inflate your reported coverage even when your compute-optimised fleet is completely unprotected.Sun, 21 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/10-iam-least-privilege-before-bucket-audit/https://replatform.in/blog/10-iam-least-privilege-before-bucket-audit/S3 bucket policies are the most-audited control in AWS security reviews. The more dangerous exposure is the assume-role chain that grants a CI/CD pipeline or EKS service account the ability to reach those buckets through a sequence of role hops that no single policy document shows.Sun, 21 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/11-snowflake-auto-suspend-by-workload/https://replatform.in/blog/11-snowflake-auto-suspend-by-workload/Snowflake's default auto-suspend of 600 seconds is expensive for interactive query warehouses. But dropping every warehouse to 60 seconds introduces resume latency that breaks ETL SLAs. The right setting varies by workload type and query gap distribution.Sun, 21 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/12-cost-ownership-not-visibility/https://replatform.in/blog/12-cost-ownership-not-visibility/Every mid-market engineering organisation has a cost dashboard. Bills keep growing anyway. The bottleneck is not visibility — it is the absence of a named human accountable for each cost line, and the absence of a workflow that closes the loop between a cost finding and a code change.Sun, 21 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/01-bigquery-teardown/https://replatform.in/blog/01-bigquery-teardown/A six-week audit, one D2C warehouse, and the seven faces of the same antagonist — every dollar found in the audit was a dashboard inheriting a developer habit nobody had time to question.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/02-cost-per-query-cfo/https://replatform.in/blog/02-cost-per-query-cfo/A short essay on the dashboard that should replace your FinOps slide — one metric, three platforms, the SQL to compute it, and the governance model that survives contact with finance.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/03-dont-migrate-snowflake/https://replatform.in/blog/03-dont-migrate-snowflake/A contrarian post from a team that sells migrations — the 5-year payback math, the five fixable patterns most projections miss, and the one signal that means migration actually is the right call.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/04-bq-to-databricks-the-case-for-leaving/https://replatform.in/blog/04-bq-to-databricks-the-case-for-leaving/Engineering comparison of BigQuery and Databricks. Architecture, storage, compute, pricing economics, and a worked cost projection across three workload shapes. The honest answer on which fits your stack.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/05-bq-to-databricks-sql-translation/https://replatform.in/blog/05-bq-to-databricks-sql-translation/Part 2 of 3. Real before/after code for the dialect translation gotchas that turn a 'two-week port' into a six-week one — date_trunc argument order, ambiguous columns in nested CTEs, INFORMATION_SCHEMA differences, the translator-pass mental model, and the regex patterns that automate the bulk of the work.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/06-bq-to-databricks-cutover-playbook/https://replatform.in/blog/06-bq-to-databricks-cutover-playbook/Part 3 of 3. The operational playbook for a BigQuery to Databricks cutover on a real workload — staged wave plan, dedup losers, second-writer detection, the DRY_RUN green but TABLE_OR_VIEW_NOT_FOUND in PROD gotcha, and the federation question.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/07-why-every-team-gets-different-numbers/https://replatform.in/blog/07-why-every-team-gets-different-numbers/Part 1 of 2. The 4-teams-4-definitions problem — same metric, different numbers, all of them technically correct. The matrix of intentional vs unintentional divergence, why semantic layers usually fail to solve it, and the star-schema-with-flags pattern that does.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/08-building-the-base-layer-star-schema-with-flags/https://replatform.in/blog/08-building-the-base-layer-star-schema-with-flags/Part 2 of 2. The actual build — what goes in dim_merchant vs fact_transactions, why partitioned-by-date and clustered-by-merchant beats every alternative, the boolean flag pattern that replaces 'test order exclusion' duplicated in 10 scripts, and the 4-phase rollout for 800+ existing analytics jobs.Tue, 16 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/what-a-discovery-sprint-finds/https://replatform.in/blog/what-a-discovery-sprint-finds/The categories of waste, drift, and risk that a thorough pre-migration assessment surfaces every time — and the deterministic methodology behind each finding. No client identifiers, no hypothetical horror stories.Sun, 14 Jun 2026 00:00:00 GMTYashhttps://replatform.in/blog/redshift-to-snowflake-migration-playbook/https://replatform.in/blog/redshift-to-snowflake-migration-playbook/An honest TCO frame and the DDL-level translation gotchas that break the timeline.
