Question: What Is VPC And What Are Its Benefits?

What is Nexus VPC and what are its benefits?

VPC is a feature available for Nexus switches.

You can bundle links from two different switches that are running the vpc feature and config.

It helps with doubling the bandwidth and creates a loop free topology (from STP perspective).

VSS does the same thing for IOS switches using MEC..

What is VPC in simple words?

A virtual private cloud (VPC) is a virtual network dedicated to your AWS account. It is logically isolated from other virtual networks in the AWS Cloud. … You can specify an IP address range for the VPC, add subnets, associate security groups, and configure route tables. A subnet is a range of IP addresses in your VPC.

What is the purpose of VPC in AWS?

Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

Which statement is true for AWS Lambda?

AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you. You can use AWS Lambda to extend other AWS services with custom logic, or create your own back-end services that operate at AWS scale, performance, and security.

When the vPC peer link is lost, the operational secondary switch suspends all of its vPC member ports while the vPC member ports remain on the operational primary switch. … If both switches reload, and only one switch boots up, auto-recovery allows that switch to assume the role of the primary switch.

What is difference between vPC and port channel?

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). … However, the key difference between vPC and VSS is that VSS creates a single logical switch.

What is difference between port channel and EtherChannel?

“EtherChannel” or “Link Aggregation” is the particular technology that allows you to bundle several links between two devices and use them simultaneously as a single interface. “Port-channel” is the name of this virtual interface in IOS.

Why do we use VPC?

Amazon VPC enables you to build a virtual network in the AWS cloud – no VPNs, hardware, or physical datacenters required. You can define your own network space, and control how your network and the Amazon EC2 resources inside your network are exposed to the Internet.

Do I really need a VPC?

You need a VPC: a virtual private network that keeps your servers safe from the ravages of the public internet, just like they were in your old data center. … But these days, when I build new applications in the cloud or talk to other builders doing the same, VPCs don’t always enter the conversation.
