Our server has 75M daily TPS which generates a lot of ops work, I’m often asked “What do you guys do when you’re on call?” this blog will demon straight how we do troubleshooting in a distributed system.

Our team recently had a performance issue with some data processing. Every day we have 24 files of 30GB generated in S3, and we’re having a Fargate cluster to download and process those data, it takes 12 hours to processing all 600+GB files, which is too slow as we want to increase the size of file for processing. After a serial of improvement, we successfully reduce the processing to 1.5 hours.

This is a sample project to explain what improvement we’ve done: https://github.com/ADU-21/s3-parallel-download

DynamoDB was announced by Amazon CTO Werner Vogels on in 2012, 14 years after NoSQL was proposed in 1998. It supports key-value and document-oriented structure storage.

Our client recently has a deployment system that has been in use for more than 10 years and wants to migrate to the cloud, this blog shows how we migrate it step by step from a huge single application to serverless by AWS Step funtion.

Big things, fast, minimal set up, maximum security, low cost.
