Lessons learned from using AWS Data Pipeline
One of the projects I worked on last year had a requirement to sync daily snapshots of data from Amazon RDS to Amazon S3 in order to support other internal services that ingested from S3 data providers.
I decided to use AWS Data Pipeline since it seemed to be a good fit for our use cases and worked well in a proof-of-concept.
This turned out to be a less than ideal solution although it did the job, and I learned several lessons from the experience.

One of the most reliable ways to build financial security is to save part of every paycheck as soon as you’re able, so you can both enjoy life in the moment and handle whatever life throws your way.
It’s harder to save today than it was a few decades ago thanks to an inflated cost of living.
