How does BGP improve cloud connectivity?

BGP (Border Gateway Protocol) is a standardized routing protocol used to exchange routing information between different autonomous systems (AS) on the internet. It facilitates the selection of optimal paths for data transmission based on network policies and conditions, enabling efficient and reliable communication across diverse network environments. Since it is an External Gateway Protocol it can be used to secure connect with a cloud service using a secure router which prevents authorized access.

BGP is a protocol that, is used to connect virtual networks of the cloud provider's infrastructure to the Internet. This allows for efficient communication and routing between different networks, enabling the uninterrupted flow of traffic between cloud-based services and the Internet.

BGP stands for Border Gateway Protocol, and it's the internet's unsung hero, silently ensuring your data gets delivered efficiently. Imagine BGP as the GPS system of the internet, but for data packets instead of cars. It determines the most efficient route for your data to travel across the vast network of interconnected computers.
