AWS VPC Overview & Components

A virtual private cloud (VPC) is a virtual network dedicated to the AWS account. It is logically isolated from other virtual networks in the AWS cloud.

VPC allows the user to select IP address range, create subnets, and configure route tables, network gateways, and security settings.

VPC Sizing

VPC allows VPC Peering connections with other VPC within the same or different AWS accounts

A connection between your VPC and corporate or home network can be established, however, the CIDR blocks should be not be overlapping for e.g. VPC with CIDR 10.0.0.0/16 can communicate with 10.1.0.0/16 corporate network but the connections would be dropped if it tries to connect to 10.0.37.0/16 corporate network cause of overlapping ip addresses.

VPC allows you to set tenancy option for the Instances launched in it. By default, the tenancy option is shared. If dedicated option selected, all the instances within it are launched on dedicated hardware overriding the individual instance tenancy setting

Deletion of the VPC is possible only after terminating all instances within the VPC, and deleting all the components with the VPC for e.g. subnets, security groups, network ACLs, route tables, Internet gateways, VPC peering connections, and DHCP options

VPC needs a set of IP addresses in the form of a Classless Inter-Domain Routing (CIDR) block for e.g, 10.0.0.0/16, which allows 2^16 (65536) IP address to be available

Allowed CIDR block size is between

CIDR block from private (non-publicly routable) IP address can be assigned

It’s possible to specify a range of publicly routable IP addresses; however, direct access to the Internet is not currently supported from publicly routable CIDR blocks in a VPC

CIDR block once assigned to the VPC cannot be modified.  NOTE – You can now resize VPC. Read AWS blog post.

Each VPC is separate from any other VPC created with the same CIDR block even if it resides within the same AWS account

/28 netmask (minimum with 2^4 – 16 available IP address) and

/16 netmask (maximum with 2^16 – 65536 IP address)

10.0.0.0 – 10.255.255.255 (10/8 prefix)

172.16.0.0 – 172.31.255.255 (172.16/12 prefix)

192.168.0.0 – 192.168.255.255 (192.168/16 prefix)

In terms of security, we create custom AWS VPC with public & private subnets but to access internet on the private subnet, we need to add NAT gateway or NAT instance, check out one of the methods. #awsskills #awsvpc #awsnetworking #awsnetwork #vpc #vpctraining #networking #ITLearn360 #subnetting #security #accesport #internetgate #routetable #awsinstance #awssupport (at United States) https://www.instagram.com/p/BqiVXF1BeDC/?utm_source=ig_tumblr_share&igshid=1pzfzw1csgkea
