Thoughts on scaling

• The initial implemantaion is using a simple micro serivce architecture as illustrated below:

• However if we are going to scale the system, probably these points can be improved:

• Decoupling the stats service from the main service and create a separate service for stats
• Adding a job service to prevent micro seconds delay of writing to stats before retrieving urls
• Adding a Router, Sinatra could be an option
• Adding a load balancer, probably Nginx
