1) What is cloud computing ?
Cloud computing is the on-demand delivery of IT resources and applications via the internet with pay-as-you-go paying.
2) What are cloud computing deployment models ?
1) Cloud based deployment (all-in-cloud based model) : All components of apps run on cloud
2) Hybrid deployment model: A mix of cloud and on-premises resources.
A hybrid deployment model is an architectural pattern providing connectivity for infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud

IaaS - Infrastructure As A Service
PasS - Platform As A Service
SaaS - Software As A Service

5) What is an AWS region ?
An AWS region is a physical geographic location that consists of a cluster of data centers.
6) What is Availability Zone ?
An Availability Zone is one or more data centers within a region that are designed to be isolated from failures in other Availability Zones
7) What is object storage, file storage and block storage ?
Block storage manages data at a device level as addressable blocks.
File storage manages data at the operating system level as files and folders.
Object storage manages data as objects that contain both data and metadata, manipulated by an API.
8) What is VPC (Virtual Private Cloud)?
The Amazon Virtual Private Cloud (Amazon VPC) is a custom-defined virtual network
within the AWS Cloud.
Amazon VPC is the networking layer for Amazon EC2, and it allows you to create your own private virtual network within the cloud.
The process of dividing a network into smaller network sections is called sub netting.
Public subnet: route table directs the traffic to VPC's Internet Gateway (IGW).
Priavate subnet: route table doesn't directs traffic to VPC's IGW
VPN only subnet: route table directs the subnets traffic to VPC's VPG(Virtual Priavate Gateway) & does not have a route to the IGW.

8) What is VPC (Virtual Private Cloud)?
The Amazon Virtual Private Cloud (Amazon VPC) is a custom-defined virtual network
within the AWS Cloud.
Amazon VPC is the networking layer for Amazon EC2, and it allows you to create your own private virtual network within the cloud.
- A VPC is an isolated portion of the AWS cloud populated by AWS objects, such as Amazon EC2 instances.
- You must specify an IPv4 address range for your VPC.
- Specify the IPv4 address range as a Classless Inter-Domain Routing (CIDR) block
- for example, 10.0.0.0/16.
- You cannot specify an IPv4 CIDR block larger than /16.
- You can optionally associate an Amazon-provided IPv6 CIDR block with the VPC.
The process of dividing a network into smaller network sections is called sub netting.
- Use the CIDR format to specify your subnet's IP address block (e.g., 10.0.0.0/24).
- Block sizes must be between a /16 netmask and /28 netmask.
- A subnet can be the same size as your VPC.
- An IPv6 CIDR block must be a /64 CIDR block.
Public subnet: route table directs the traffic to VPC's Internet Gateway (IGW).
Priavate subnet: route table doesn't directs traffic to VPC's IGW
VPN only subnet: route table directs the subnets traffic to VPC's VPG(Virtual Priavate Gateway) & does not have a route to the IGW.
