Should I use AWS default VPC?
There would be no real problem with you using the default VPC and adding a private subnet but this is certainly not ideal. The default VPC is designed so that you can quickly deploy resources and not have to think about the underlying network. If you are just doing a very basic deployment then it works great.
Is VPC same as VLAN?
A VLAN is a virtual LAN. Like a subnet, a VLAN is a way of partitioning a network, but the partitioning takes place at a different layer within the OSI model (layer 2 instead of layer 3). A VPC will have a dedicated subnet and VLAN that are only accessible by the VPC customer.
How set static IP AWS instance?

What is static IP in AWS?
Short description. An Elastic IP address is a static public IPv4 address associated with your AWS account in a specific Region. Unlike an auto-assigned public IP address, an Elastic IP address is preserved after you stop and start your instance in a virtual private cloud (VPC).
Why should I not use default VPC?
Avoid them when using automation. On the networking side, the default VPC enables the assignment of public addresses in public subnets by default. This is a security no-no. If a developer errs in automation or the console, you don’t want the instance to be reachable by the Internet.
Should I remove default VPC?
If you do not have any resources inside your default VPC, you will not have any impact. If you choose to delete the Default VPC, you will not have any ability to re-recreate it. If for some reason you require a default VPC in the future, you will need to contact AWS Support to have your default VPC re-created.
Is AWS VPC traffic encrypted?
All traffic within a VPC and between peered VPCs across regions is transparently encrypted at the network layer when using supported Amazon EC2 instance types.
Does AWS VPC support multicast?
Historically, AWS VPCs have not supported multicast. The AWS engineers have recently developed a proof-of-concept multicast overlay, that has support for IGMP snooping.
What should I look for when creating a VPC for AWS?
If you’re creating a VPC for use with another AWS service, check the service documentation to verify if there are specific requirements for the IP address range or networking components.
How are private IP addresses assigned to a VPC instance?
When you launch an instance into a VPC, a primary private IP address from the IPv4 address range of the subnet is assigned to the default network interface (eth0) of the instance. Each instance is also given a private (internal) DNS hostname that resolves to the private IP address of the instance.
How to get started with Amazon virtual private cloud (Amazon VPC)?
To get started with Amazon Virtual Private Cloud (Amazon VPC), you create a VPC and subnets. For a general overview of Amazon VPC, see What is Amazon VPC? . 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.
Do Amazon EC2 and Amazon VPC support IPv4 and IPv6?
Amazon EC2 and Amazon VPC support the IPv4 and IPv6 addressing protocols. By default, Amazon EC2 and Amazon VPC use the IPv4 addressing protocol. When you create a VPC, you must assign it an IPv4 CIDR block (a range of private IPv4 addresses). Private IPv4 addresses are not reachable over the Internet.
