What is NAT gateway?
NAT Gateway is a highly available AWS managed service that makes it easy to connect to the Internet from instances within a private subnet in an Amazon Virtual Private Cloud (Amazon VPC). Previously, you needed to launch a NAT instance to enable NAT for instances in a private subnet.
What is the use of 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.
What are the benefits of a VPC?
Secure. Amazon VPC provides advanced security features, such as security groups and network access control lists, to enable inbound and outbound filtering at the instance and subnet level. In addition, you can store data in Amazon S3 and restrict access so that it’s only accessible from instances inside your VPC.
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.
How does a VPC work?
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.
Is AWS VPN free?
For managing remote access, AWS Client VPN connects your users to AWS or on-premises resources using a free VPN software client. AWS Client VPN is a fully-managed, elastic VPN service that automatically scales up or down based on user demand.
What is VPC peer link?
vPC peer link: The vPC peer link is the link used to synchronize states between the vPC peer devices. The vPC peer link carries control traffic between two vPC switches and also multicast, broadcast data traffic. In some link failure scenarios, it also carries unicast traffic.
What is difference between VSS and vPC?
What is the difference between VSS and vPC? 2) In VSS there will be single control plane for both the switches, where as in vPC there will be separate control plane for every switch. 3) VSS can support L3 port-channels across multiple chassis,however, vpc is used for L2 port-channels only.
What is VPC in Nexus and what are its benefits?
Benefits of vPC A virtual port channel (vPC) allows links that are physically connected to two different Cisco Nexus 7000 Series devices to appear as a single port channel to a third device. The third device can be a switch, server, or any other networking device that supports link aggregation technology.
Does VPC cost money?
You will be charged on an hourly basis, for each hour the traffic mirroring sessions were active on ENIs. For US East(Ohio) Region, the hourly rate is $0.015. This will result in a charge of $54. Amazon VPC ingress routing is available in all AWS commercial and AWS GovCloud (US) Regions at no additional cost.
Why do we need VPC peering?
A VPC peering connection helps you to facilitate the transfer of data. For example, if you have more than one AWS account, you can peer the VPCs across those accounts to create a file sharing network. You can also use a VPC peering connection to allow other VPCs to access resources you have in one of your VPCs.
Is VPC peering free?
There is no charge for setting up or running a VPC peering connection. Data transferred across peering connections is charged at $0.01/GB for send and receive, regardless of the Availability Zones involved.
What happens if vPC peer link goes down?
vPC peer-link failure If peer-link fails, then all the member ports from vPC secondary node will be suspended. Here important to note, keep-alive is active in this scenario, which allowing nodes to exchange heartbeat. Solution: Make sure peer-link is UP and running.
Is AWS Internet gateway free?
For S3 and DynamoDB, you can create a Gateway VPC Endpoint which is free and lets you communicate to S3 and DynamoDB from private subnets without natting. For some AWS services, you can create an Interface VPC Endpoint which is cheaper than a NAT gateway.
