Study Notes
- VPC (Virtual Private Cloud) is a public cloud capability that allows users to define and control isolated virtual networks and deploy cloud resources into those networks.
- In a standard public cloud, an administrator finds a backbone that carries all traffic and creates segmentation to separate clients and applications.
- A router network function enables communication between segments, and a firewall function provides filtering capabilities to control traffic flow between segments.
- A NAT-ing function provides internet connectivity, and a VPN function extends enterprise connectivity.
- In a traditional cloud environment, network functions are done with appliances that require infrastructure administrators to configure using proprietary interfaces.
- Virtual networking introduces these capabilities as a service, allowing users to create functions and segmentation with a UI, CLI, or API.
- Users can create custom networks with connectivity to the enterprise and the internet without needing to know proprietary interfaces.
- Each virtual network is completely isolated from others until connected by the user.
- Benefits of VPC include built-in security, scalability, customizability, and flexibility, allowing developers to become more agile and reduce costs.
