What is VPC topology?

AWS VPC Topology VPCs are used in a single region. But they are a multi-availability zone, which basically means that each subnet you create has the ability to live in a different availability zone or in a single availability zone. All of the subnets that you create within a VPC can route to each other by default.

What are components of VPC?

Elements of a VPC

  • IPv4 and IPv6 address blocks.
  • Subnet creation.
  • Route tables.
  • Internet connectivity.
  • Elastic IP addresses (EIPs)
  • Network/subnet security.
  • Additional networking services.

What is a VPC endpoint interface?

A VPC Endpoint enables you to connect the VPC to your AWS services without the need of an Internet Gateway, NAT device, VPN or a AWS Direct Connect connection. Instances in your VPC doesn’t use public IP addresses to communicate with AWS service, instead it uses VPC Endpoint for that.

What is VPC and how it works?

A virtual private cloud (VPC) is a secure, isolated private cloud hosted within a public cloud. VPC customers can run code, store data, host websites, and do anything else they could do in an ordinary private cloud, but the private cloud is hosted remotely by a public cloud provider.

How many ports can be in a vPC?

Single Homed Fabric Extender vPC Topology The Cisco Nexus 5000 Series switch can support up to 12 configured single homed Fabric Extenders (576 ports) with this topology however only 480 dual homed host servers can be configured in a vPCs with this configuration.

What is vPC configuration?

vPC (Virtual Port-Channel), also known as multichassis EtherChannel (MEC) is a feature on the Cisco Nexus switches that provides the ability to configure a Port-Channel across multiple switches (i.e. vPC peers). vPC is similar to Virtual Switch System (VSS) on the Catalyst 6500s.

What is VPC architecture?

It builds a virtual private network (VPC) environment with public and private subnets where you can launch AWS services and other resources. Use this Quick Start as a building block for your own deployments.

How many CIDR are in a VPC?

You assign a single Classless Internet Domain Routing (CIDR) IP address range as the primary CIDR block when you create a VPC and can add up to four (4) secondary CIDR blocks after creation of the VPC. Subnets within a VPC are addressed from these CIDR ranges by you.

What is difference between gateway endpoint and interface endpoint?

An interface endpoint is powered by PrivateLink, and uses an elastic network interface (ENI) as an entry point for traffic destined to the service. A gateway endpoint serves as a target for a route in your route table for traffic destined for the service.

How many VPC are in one account?

You can’t have more than 255 gateway endpoints per VPC. This is the combined quota for the maximum number of interface endpoints and Gateway Load Balancer endpoints in a VPC. To increase this quota, contact AWS Support.

What is difference between vPC and port channel?

Here you can see that Virtual Port channel (vPC) is configured using the interfaces of two switches. One of the key difference between the two technologies (port-channel and virtual port-channel ) is that port channels support both Layer 2 and Layer 3. vPC on the other hand only supports Layer 2.
