- 37. Provide a better experience to growing markets
- 39. When should I add a Zone? If latency of complete request exceeds threshold? Not really – There are many layers contributing to the latency outside of Atlas Metrics in Atlas? Maybe – performance metrics Maybe – mongos logs – cross-reference IP against IP-GeoLocation DB / Service It’s beyond Atlas - A combination of: • Data Set growing from certain countries & sub-divisions Use Aggregation Framework, BI Connector or Spark Connector for Analytics • CDN / API Management Metrics: AWS CloudFront / API Gateway, Akamai, etc. • Planned Expansion: New features targeting specific markets

Concise and global, it will look like Your driver will use this address to discover every mongos in the cluster globally Taking advantage of the MongoDB 3.6 driver support for SRV records … so you can deploy the same application code everywhere - symmetrically mongodb+srv://user:pass@globalCluster-rzeyq.mongodb.net

- 52. Where this is going and limits
- 53. Massive reach MongoDB Atlas • in-country regions for 27% of the world population • with a much higher percent served by regions in nearby countries Available in 56 global cloud regions • AWS: 15 regions (38 availability zones) • Azure: 26 regions (26 availability zones w/ 60 Fault Domains) • GCP: 15 regions (38 Availability zones)
- 54. Africa • S. Africa announced by Azure; a long way from most of Africa’s population, however • Biggest economies in Africa: Nigeria, South Africa, Egypt; with Ethiopia now the fastest growing Middle East • We’ll see China • It’s complicated... There are gaps Russia • It’s also complicated… • Frankfurt remains best bet but also Finland on Google Cloud Special / Government / Compliance contexts
- 55. But MongoDB runs everywhere Over time the entire world will be well served by major cloud infrastructure You can always run your own MongoDB outside of where the big public cloud • MongoDB Ops Manager / MongoDB Cloud Manager • Live Migrate to MongoDB Atlas when ready So you can have a seamless development experience in any context
