Cloud network egress costs is one of the reasons why increasingly infrastructure vendors likely to incur high data transfer costs (database / data warehouse services, message buses, machine learning, etc..) are moving to introduce BYOC or "Bring Your Own Cloud" deployment model (Data Plane runs in the customer VPC - original Databricks deployment model), instead of only pure SaaS (Data Plane runs in the vendor VPC - e.g. Snowflake) in their cloud offerings.
Databricks now has fully hosted too, but Snowflake still did not go the other way to introduce BYOC. Newer entrants, however - RedPanda, AnyScale, ClickHouse... - are going the way of providing both BYOC and pure SaaS options in their cloud. There are many other reasons to prefer BYOC, legal, security, data privacy, but network egress costs is one of them.
