Description: VPC routing is the process of directing traffic within a Virtual Private Cloud (VPC) using routing tables. Each VPC has an associated routing table that determines how traffic is sent between subnets and to or from the Internet. Routing tables contain rules, known as routes, that specify the destination of traffic and the next hop, which can be an IP address, a gateway, or a network resource. This mechanism is fundamental for efficient and secure communication between instances within the cloud, as well as for access to external services. VPC routing allows users to define security policies and access control, ensuring that only authorized traffic can flow between different parts of the infrastructure. Additionally, it facilitates the creation of complex network architectures, where different environments, such as development, testing, and production, can be segmented within the same VPC. The flexibility in configuring routing tables allows organizations to tailor their infrastructure to their specific needs, optimizing the performance and security of their cloud applications.
