VIRTUAL PRIVATE CLOUD

VPC stands for Virtual Private Cloud. It’s a service offered by cloud providers like AWS, VPC is a virtual network that closely resembles a traditional network that you'd operate in your own data center. After you create a VPC, you can add subnets.

1)subnets:

           Divide your VPC into subnets, which can be public or private. Public subnets are accessible from the internet, while private subnets are not.

2) Route Table:

            A set of rules, called routes, that determines where network traffic is directed within a VPC. Each subnet must be associated with a route table to define how traffic is routed.

3)Internet Gateway:

              A VPC component that enables resources within the VPC to communicate with the internet. It allows instances in public subnets to send and receive internet traffic.   

4)NETWORK ADDRESS TRASULATION GATEWAY:

                                   Enables instances in private subnets to access the internet for updates and patches, while preventing unsolicited inbound traffic.

5)Security Groups and Network :

                             These act as firewalls to control inbound and outbound traffic to your resources.  

6) NETWORK ACCESS CONTROL LISTS:

                             which are stateful and automatically allow return traffic for allowed inbound traffic, Network ACLs are stateless. This means you must define rules for both inbound and outbound traffic separately.

7)VPC FLOW LOGS:

              VPC Flow Logs is a feature in Amazon Web Services (AWS) that allows you to capture information about the IP traffic going to and from network interfaces in your Virtual Private Cloud.
