Why do we use VPC and subnets, and firewalls? Explain briefly.

Question

Accepted Answer

VPC and subnets are used to create isolated network environments in the cloud. Firewalls are used to control network traffic.

VPC (Virtual Private Cloud) allows users to create their own virtual network in the cloud, providing isolation and control over network resources.
Subnets are subdivisions of a VPC and allow for further segmentation and organization of resources.
Firewalls are used to enforce security policies and control inbound and outbound network traffic.
Firewalls can be configured to allow or deny specific types of traffic based on rules and policies.
For example, a company may use a VPC to separate their production environment from their development environment, with different subnets for each.
Firewalls can then be used to restrict access to certain resources or services within the VPC.
By using VPC, subnets, and firewalls, organizations can create secure and isolated network environments in the cloud.
