  • 42. Introduction
  • 43. The AWS Global Infrastructure - connected by high-speed backbone network between the regions.
    • Made of 26+ regions. Each region has two or more Availability Zones - for redundancy. An availability zone can be thought of as a physical data center. Each data center has redundant power sources and redundant networking.
    • AWS Outposts - extends AWS services into dedicated hardware in your data center or corporate location. For using AWS services on-premises. For using AWS APIs on-premises.
    • AWS Local Zone - exxtends the AWS Availability Zone closer to end-users for lower latency. I guess it's like an Availability Zone without the full-fledged characteristics of a Data Center?
    • AWS Wavelength Zone - extends AWS using 5G wireless. For singled-digit ms latency to mobile device users.
    • AWS CloudFront is a CDN with 13+ Regional Edge Caches and 400+ Edge locations.

  2. The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:
    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)
    

    We will refer to the first block as "24-bit block", the second as "20-bit block", and to the third as "16-bit" block. Note that (in pre-CIDR notation) the first block is nothing but a single class A network number, while the second block is a set of 16 contiguous class B network numbers, and third block is a set of 256 contiguous class C network numbers.
