These are only the defaults. Many of these can be changed by contacting AWS or other ways. Refer to the reference link for details.
Flow logs per single network interface, single subnet, or single VPC in a region = 2
VPCs per region = 5
Amazon VPC provides following features to increase and monitor the security for your VPC:
Security groups - Act as a firewall for associated Amazon EC2 instances, controlling both inbound and outbound traffic at the instance level.
Network access control lists (ACLs) - Act as a firewall for associated subnets, controlling both inbound and outbound traffic at the subnet level.
NAT is a method of remapping one IP address space into another. Advanced NAT implementations feature IP masquerading, which allows to share one Internet-routable IP address of a NAT gateway for an entire private network. In AWS, you can either use a NAT instance or a NAT gateway.
Host a simple, public-facing website
Can create security group rules which allow the webserver to respond to inbound HTTP and SSL requests from the Internet while simultaneously prohibiting the webserver from initiating outbound connections to the Internet.
Can select "VPC with a Single Public Subnet Only".
Amazon VPC lets you provision a logically isolated section of the 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 use both IPv4 and IPv6 in your VPC.
We will see topics such as DMZ, jump server, bastion host, NAT etc.
Will discuss important networking terms which will help understand Amazon VPC service better: VPC itself, IP subnet, jump hosts, private IP address spaces, NAT and ICMP.
Amazon API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale.
Understanding the Amazon SWF application logical elements will help you determine how to build your own flow applications.
Amazon Simple Workflow Service (SWF) helps developers build, run, and scale background jobs that have parallel or sequential steps. You can think of Amazon SWF as a fully-managed state tracker and task coordinator in the Cloud.

CloudMaterials is my blog to share notes and learning materials on Cloud and Data Analytics. My current focus is on Microsoft Azure and Amazon Web Services (AWS).
I like to write and I try to document what I learn to share with others. I believe that knowledge is useless unless you share it; the more you share, the more you learn.
