Taking an existing system which consumes 4.3m Tweets per day then making it more Scalable and Testable. What happens if we need 10x the scale? Will look at: Signing up to the Twitter API Simplest possible C# app working consuming the Twitter stream: Making more scalable with RabbitMQ ELK (Elasticsearch, Logstash, Kibana) stack Caching with Redis SqlBulkCopy ETL patterns This application has been in development for 6 months. It is born out of 7 years of writing similar enterprise software - can my system handle 2x or 10x the load if I need it? Can I prove my system is working ie Auditable/Testable and Dashboard overviews.
