Design remarks:

  • All the resources run inside a VPC. This allows them to communicate without exposing any endpoint publicly.
  • Buzz uses a container running on Fargate to act as reducer (HComb). This is one way among others to allow Lambdas to exchange data between each other. We believe it is the best solution to keep the latency of queries as low as possible. The drawback is that the container initialization time is quite long, which makes the first query very slow!
