Christian Hujer (https://www.linkedin.com/in/christianhujer/) and Rajan Patil (https://www.linkedin.com/in/rajan-patil-920b1815/) will be taking us through scenarios as mentioned below-
Tale 1: Analyzing and Solving a 504 Gateway Timeout problem on AWS
A change in the way users used the system resulted in a downtimes of services caused by `504 Gateway Timeout` on the ELBs.
• What does that mean?
• What is causing it?
• And how to fix it?
This touches all layers of a project from DevOps and Infrastructure via understanding HTTP and TCP/IP networking and POSIX operating systems to proper resource handling in source code (in this case, Java).
The problem: 504 Gateway Timeouts
The analysis: From structure to tools how we found the culprit with system knowledge and systematic search
The solution - once more: Clean Code!
Tale 2: Migrating 190M records from DynamoDB and S3 to MongoDB
In one of our projects we had to migrate 190M records from DynamoDB and S3 to MongoDB.
In a live system.
This is the story of how we achieved that: how we did that, what went wrong along the way, and what we did about those things. This is about both, the migration script as well as the service reprogramming.
