"EC2 – Other" is the third largest line on the bill and you run no EC2 instances. That's NAT gateway charges from a pipeline that is entirely Lambda, S3 and Athena. Five levers for cutting the AWS cost of Salesforce data pipelines, in the order worth pulling them.
You re-run the same extract for the same window and get a different set of rows. Nothing errored. You were paginating a result set that kept changing while you read it. Here's how to build a Zoho CRM to S3 pipeline whose runs are repeatable, from closed read windows to Bulk Read and deletions.
Your dashboard shows four percent more opportunities than Salesforce, and the extra rows were all deleted months ago. Incremental sync on SystemModstamp can never see a record that no longer exists. Here's how to build a Salesforce data lake on AWS that stays equal to the source.
A plugin quietly reverts after every deploy and nobody knows why. That is what happens when Git and wp-admin both think they own the file tree. Here is how to build a deployment workflow where the repo is the source of truth and the database only ever travels one way.
A deploy key in GitHub secrets is a shell on your production server, handed to a container you don't control, running code from maintainers you've never met. Here's how to build the pipeline so a leaked key isn't worth much: forced commands, scoped sudo, pinned actions and a real approval gate.
Loki was fast until someone added one more label. Now queries time out during incidents and the index no longer fits in memory. Here's the model you have to internalise, what replaced Promtail, and how to keep labels, retention and storage costs under control.
A green pipeline that ships a broken build is worse than a red one. Here is how to order stages so failures surface in seconds, stop shell pipes from swallowing exit codes, and write failure output that tells the next engineer exactly what to fix.
Metrics tell you that something is wrong. Traces tell you where. Logs tell you why. Use them in that order and each step narrows the search — start with logs and you are grepping a firehose. Here is what each one is actually for, and the field that connects all three.
Put a CDN in front of a dynamic site carelessly and it will cache one user's personalised page and serve it to everyone — invisibly, because your logged-in browser looks fine. Here is how to classify routes, set cache headers that hold, and run the two curl commands that catch the leak.
The top search result tells you to run docker system prune -a --volumes. It frees the space and deletes your database. Here is how to measure Docker disk usage properly, reclaim it from safest to most destructive, and fix the logs that Docker never reports on.
