Description
At Salesforce, to provide better resilience and performance, we host multiple zones containing millions of DNS records across many DNS providers. However, this increases the complexity for client applications, the operations teams, and even the DNS admin managing DNS records. The client applications would need to know which provider hosts which zone and make API calls for DNS CRUD to the specific provider. When we add new zones and migrate zones between DNS providers, things get more complex.
To solve this problem, we built a highly available and scalable cloud-based microservice named Athena that hides all the complexity from the end-users. Athena acts as the single Rest API endpoint in front of all the DNS providers. The end-users send all DNS CRUD requests to Athena without needing to know which providers host the zones. Upon receiving a request, Athena automatically figures out the provider for the zone, converts the request to the right format based on the provider's Rest API specifications, sends the request to the provider, and converts the return message to a standard response for the end-user.
In this presentation, we will talk about the architecture of Athena, availability, scalability, zone-vendor mappings management, account management, development/release pipeline, monitoring, and more.
