Microservices War Reports: Two Tales from real life Microservices projects

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.

• Planning

• Testing

• Pitfalls

• Firefighting
