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.
Learn about the key concepts and benefits of Virtual Private Cloud (VPC), including network segmentation, router and firewall functions, and the advantages of virtual networking over traditional cloud environments. Understand how VPC enables customizability, scalability, and security for developers and administrators. Discover how VPC introduces network functions as a service, allowing users to create and manage virtual networks with ease.
