• Question 44:

  Universal Containers has a microservices architecture on Heroku. One microservice. named the Metrics Microservice. periodically fetches metrics from a fleet of loT sensors.

As a result, adding microservices to the architecture causes performance issues.

  How should an Architect recommend changing this architecture to improve its scalability?

  A. Configure each microservices to directly fetch the sensor metrics that are relevant to it.
  B. Use Private Space DNS Service Discovery to reduce the amountof time required for the Metrics Microservice to obtain each other microservice's IP address
  C. Configure the other microservices to pull the Metrics Microservice for updates every five seconds
  D. Use Apache Kafka on Heroku to publish metrics to a topic that the other microservices can consume.
