Peering can be achieved by connecting a route between two VPCs on the same account or two VPCs on different accounts in the same region. VPC peering is a one-to-one connection, but users can connect to more than one VPC at a time. [9] To achieve a one-to-many connection between VPCs, you can deploy a transit gateway (TGW).
A virtual firewall (VF) is a network firewall service or appliance running entirely within a virtualized environment and which provides the usual packet filtering and monitoring provided via a physical network firewall. The VF can be realized as a traditional software firewall on a guest virtual machine already running, a purpose-built virtual ...
The type of security technology is irrelevant when it comes to the definition of a Virtual Security Appliance and is more relevant when it comes to the performance levels achieved when deploying various types of security as a virtual security appliance. Other issues include visibility into the hypervisor and the virtual network that runs inside.
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).
Instances – When an image is put to use, it is called an instance. The configuration is executed at runtime, and the Cloud Controller decides where the image will run, and storage and networking is attached to meet resource needs. IP addressing – Eucalyptus instances can have public and private IP addresses. An IP address is assigned to an ...
The first firewall (also called the "front-end" or "perimeter" [5] firewall) must be configured to allow traffic destined to the DMZ only. The second firewall (also called "back-end" or "internal" firewall) only allows traffic to the DMZ from the internal network. This setup is considered [4] more secure since two devices would need to be ...
Virtual eXtensible LAN (VXLAN) is a network virtualization technology that uses a VLAN-like encapsulation technique to encapsulate OSI layer 2 Ethernet frames within layer 4 UDP datagrams, using 4789 as the default IANA-assigned destination UDP port number, [1] although many implementations that predate the IANA assignment use port 8472.
IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). [1] IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks.
