Amazon VPC lets you provision a logically isolated section of the Amazon Web Services (AWS) cloud where you can launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. You can also create a hardware Virtual Private Network (VPN) connection between your corporate datacenter and your VPC and leverage the AWS cloud as an extension of your corporate datacenter.You can easily customize the network configuration for your Amazon VPC. For example, you can create a public-facing subnet for your web servers that have access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.

aws vpc - What are the components of Amazon VPC?

Comment

The foremost element in Amazon VPC architecture is VPC network itself. It’s a logically separated part of AWS cloud. It’s possible to define your Virtual Private Cloud’s IP address from the range you’ve chosen. The second element is the Internet Gateway which is the connecting point between your VPC and the public internet. Subnets are the functional parts of your private cloud’s IP address range.
NAT Gateways are used to connect between instances of your private subnet with internet or other AWS services. Customer Gateways are your side of a VPN connection in AWS while Virtual Private Gateways are Amazon VPC side of VPN connection. This type of questions lies under the general or basic AWS VPC interview questions. Whether you are a fresher or have some experience, you may come across such questions so get prepared with the answer.
Element	Brief description
Virtual Private Cloud (VPC)	A logically isolated virtual network in the AWS cloud. You define a VPC’s IP address space from a range you select.
Subnet	A segment of a VPC’s IP address range where you can place groups of isolated resources.
Internet Gateway	The Amazon VPC side of a connection to the public Internet.
NAT Gateway	A highly available, managed Network Address Translation (NAT) service for your resources in a private subnet to access the Internet.
Hardware VPN Connection	A hardware-based VPN connection between your Amazon VPC and your datacenter, home network, or co-location facility.
Virtual Private Gateway	The Amazon VPC side of a VPN connection. The Customer gateway is the customer side of a VPN connection.
Peering Connection	A peering connection enables you to route traffic via private IP addresses between two peered VPCs
VPC Endpoint	Enables Amazon S3 access from within your VPC without using an Internet gateway or NAT, and allows you to control the access using VPC endpoint policies.

Subnet - A segment of a VPC's IP address range where you can place groups of isolated resources.
Internet Gateway - The Amazon VPC side of a connection to the public Internet.
NAT Gateway - A highly available, managed Network Address Translation (NAT) service for your resources in a private subnet to access the Internet.
Hardware VPN Connection - A hardware-based VPN connection between your Amazon VPC and your datacenter, home network, or co-location facility.
Virtual Private Gateway - The Amazon VPC side of a VPN connection. The Customer gateway is the customer side of a VPN connection.
Peering Connection - A peering connection enables you to route traffic via private IP addresses between two peered VPCs.
VPC Endpoint - Enables Amazon S3 access from within your VPC without using an Internet gateway or NAT, and allows you to control the access using VPC endpoint policies.

aws vpc - Explain to me why Amazon thought to create VPC?

Comment

Amazon has lots of physical data centers throughout the world. Now they were looking forward to creating virtual data centers. These data centers needed virtual networks and virtual network access. To manage this virtual cloud they have created VPC which actually gives access to clients in the virtual network with a private cloud zone. They kept access to other Amazon services.

aws vpc - what are the functions of an Amazon VPC router?

Comment

VPC router allows Amazon EC2 instances within subnets to interact with Amazon EC2 instances in other subnets within the same VPC. Virtual private gateways, subnets and Internet gateways, etc. can also communicate with each other by means of a VPC router.
Amazon KMS is a managed service that is integrated with various other AWS Services. You can use it in your applications to create, store and control encryption keys to encrypt your data. Learn AWS KMS Key Management Service.

aws vpc - What is a VPS?

Comment

Beginners who were trying AWS VPC interview questions for the first time used to get confused with this question, since these terms look similar.
Actually, VPS or Virtual Private Server is none other than the host server offered by web hosting companies like BlueHost and GoDaddy (These companies also provide shared hosting services wherein the server is shared by several users). Here, a single host divided to multiple virtual units, each having an independent function. Each of these units is virtual private servers which can work without depending on one another. You’ll get access to the complete physical server including root access.
In the case of VPC, its functions are similar to that of a VPS but its servers don’t have to place in a single location.
