VPC is Amazon Web Services (AWS) solution for providing isolated network environments for AWS resources. IP addresses in a VPC are used for communication between resources within the VPC, as well as for communication between the VPC and the Internet. There are two types of IP addresses used in a VPC: private IP addresses and public IP addresses.
The isolation between one VPC user and all other users of the same cloud (other VPC users as well as other public cloud users) is achieved normally through allocation of a private IP subnet and a virtual communication construct (such as a VLAN or a set of encrypted communication channels) per user.
A VIP address can be used to provide nearly unlimited mobility. For example, if an application has an IP address on a physical subnet, that application can be moved only to a host on that same subnet. VIP addresses can be advertised on their own subnet, [a] so its application can be moved anywhere on the reachable network without changing ...
Although VLT is a proprietary protocol from Dell Networking (formerly Force10) other vendors offer similar features to allow users to set up an aggregated link towards two (logical) different switches, where a standard aggregated link can only terminate on a single logical switch (thus either a single physical switch or on different members in ...
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
Amazon Elastic IP. Amazon's elastic IP address feature is similar to static IP address in traditional data centers, with one key difference. A user can programmatically map an elastic IP address to any virtual machine instance without a network administrator's help and without having to wait for DNS to propagate the binding.
Virtual hosting is a method for hosting multiple domain names (with separate handling of each name) on a single server (or pool of servers). [1] This allows one server to share its resources, such as memory and processor cycles, without requiring all services provided to use the same host name.
Cisco's RAPT implementation is PAT or NAT overloading and maps multiple private IP addresses to a single public IP address. Multiple addresses can be mapped to a single address because each private address is tracked by a port number. PAT uses unique source port numbers on the inside global IP address to distinguish between translations.
