The number of regions you can service without call latency and data sovereignty issues is limited
Since each pod resides in a physical data center in a region, you can’t expand to new regions without making a tough choice. You can service that region from your existing data center, sacrificing call quality and confronting data residency issues but keeping unified reporting. Or, you can open a new regional data center deployment at increased cost, while sacrificing your single, unified call center and data. This latter may not be an option if your provider does not have a data center in your desired region.
