Amazon VPC: What is it?
The
Amazon Virtual Private Cloud (VPC) solution allows you to launch AWS resources in a logically isolated virtual network of your choosing. You have complete control over your virtual networking environment, including the ability to configure network gateways, route tables, subnets, and your own range of
IP addresses. Access to resources and apps is made safe and convenient by the fact that most of the resources in your VPC are compatible with both IPv4 and IPv6.
One of AWS's primary services,
Amazon VPC, makes it easy to customize your VPC's network configuration. You can create a publicly visible subnet for your web servers that have an internet connection. It also allows you to place your backend systems, such as databases or application servers, in a subnet that is not on the internet and faces the private sector. To help manage access to Amazon Elastic Compute Cloud (Amazon EC2) instances within each subnet, Amazon VPC can be used with a number of security layers, including security groups and network access control lists.
Amazon VPC's advantages
Boost security
Secure and monitor connections, filter traffic, and restrict instance access within your virtual network.
Conserve time
Spend as little effort as possible setting up, maintaining, and confirming your virtual network.
Control and direct your surroundings
To customize your virtual network, choose your own IP address range, set up route tables, and create subnets.
How it operates
With Amazon Virtual Private Cloud (Amazon VPC), you have total control over your virtual networking environment, including resource placement, security, and connection. To begin, configure your VPC in the AWS service panel. Next, add resources such as Amazon Elastic Compute Cloud (EC2) and Amazon Relational Database Service (RDS) instances. Finally, define how your VPCs communicate with each other across accounts, Availability Zones, and AWS Regions.
Use cases
Start a basic blog or website
To improve the security posture of your online application, impose limitations on both inbound and outbound connections.
Run web apps with several tiers
Set up network connectivity and restrictions between your web servers, application servers, and databases.
Establish hybrid relationship
Establish and manage a VPC network that integrates with your AWS and on-premises services.
Pricing for Amazon's virtual private cloud
Amazon Virtual Private Cloud: Why Use It?
An Amazon Virtual Private Cloud (VPC) is free to set up and use, but you can pay for its additional capabilities using usage-based fees. Using AWS's tools and services, you can change the security, monitoring, connection, and control of your Amazon VPC. For exact pricing rates for these components, please see the following.
Other
Amazon Web Services products, such as Amazon Elastic Compute Cloud (Amazon EC2), still have usage costs, including data transmission fees. If you connect your VPC to your corporate data center using the optional hardware virtual private network (VPN) connection, the cost is per VPN connection-hour. Partial hours are billed as full hours, and data transferred over VPN connections will be taxed at standard AWS Data Transfer rates.
Features of Amazon VPC
Flow Logs
You can monitor your Amazon Virtual Private Cloud (VPC) flow logs that are sent to Amazon Simple Storage Service (Amazon S3) or
Amazon CloudWatch to gain operational insight into your network dependencies and traffic patterns, spot anomalies and prevent data leaks, and troubleshoot network connectivity and configuration issues. By looking at the additional information in flow logs, you can learn more about who initiated your TCP connections and the packet-level source and destination of traffic that passes through intermediary levels. You can also archive your flow logs to assist you in fulfilling various regulatory requirements.
Manager of IP addresses (IPAM)
IPAM makes it easier to plan, track, and monitor IP addresses for your AWS workloads. Because IPAM automatically assigns IP addresses to your Amazon Virtual Private Cloud VPC, it does away with the requirement for spreadsheet-based or internal planning tools. By showing IP consumption across several VPCs and accounts in a single operational view, it also enhances network observability.
IP Addressing
IP addresses allow resources in your VPC to connect with one another and with other resources via the internet. Amazon Virtual Private Cloud (VPC) supports both IPv4 and IPv6 addressing protocols. A VPC can be used to construct IPv4-only, dual-stack, and IPv6-only subnets, and
Amazon EC2 instances can be launched in these subnets. Furthermore, Amazon provides you with a range of options for assigning public IP addresses to your instances. Elastic IPv4 addresses, public IPv4 addresses, and IPv6 CIDRs from Amazon can all be used. Additionally, within the Amazon VPC, you can choose to give these instances their own IPv4 or IPv6 addresses.
Routing for Ingress
All incoming and outgoing traffic can be redirected to and from an internet gateway or virtual private gateway to the elastic network interface of a specific Amazon EC2 instance thanks to this feature. Send all traffic to a gateway or an Amazon EC2 instance in your Amazon Virtual Private Cloud (VPC) before it reaches your business workloads.
Analyzer for Network Access
Using Network Access Analyzer, you can verify that your network on AWS meets your network security and compliance standards. You can identify unlawful network access that doesn't meet your demands and establish your standards for network security and compliance with the aid of Network Access Analyzer. You can quickly demonstrate compliance, understand network access to your resources, and identify ways to improve your cloud security posture with the aid of Network Access Analyzer.
List of Network Access Controls
A network access control list (network ACL), an optional security feature for your VPC, acts as a firewall to manage traffic entering and exiting one or more subnets. Rules similar to those in your security groups can be used to configure network ACLs.
Network Manager
Network Manager provides features and tools to help you monitor and manage your network on AWS. Network Manager simplifies IP administration, network security and governance, connectivity management, and network monitoring and troubleshooting.
Reachability Analyzer
This static configuration analysis tool allows you to investigate and troubleshoot network reachability between two resources in your VPC. Reachability Analyzer determines the blocking factor when the source and destination resources are not reachable and produces hop-by-hop information on the virtual path between them when they are.
Groups for Security
Create security groups to act as a firewall for associated Amazon EC2 instances, controlling incoming and outgoing traffic at the instance level. At launch, an instance may be associated with one or more security groups. If you don't specify a group, the instance is automatically associated with the VPC's default group. Every instance in your VPC could belong to a different group.
Traffic Mirroring
This feature allows you to copy network traffic from an elastic network interface of Amazon EC2 instances and then move it to out-of-band security and monitoring equipment for deep packet analysis. Network and security abnormalities can be found, issues can be troubleshot, operational insights can be gained, and security and compliance policies can be created. With traffic mirroring, you may see the network packets going through your VPC directly.
Lattice
With the help of this service, you can securely connect, monitor, and safeguard conversations between your apps. Compute service connections between instances, containers, and serverless apps may be made simpler and more uniform with the help of network traffic management, access, and monitoring policies.
VPC Is Blocking Access for the Public
By providing a single declarative control that makes it easy to block direct Internet access VPCs via the Internet Gateway or Egress-only Gateway, this feature makes sure that resources in your Amazon Virtual Private Cloud (VPC) are not inadvertently made public. In the VPC, you have the option to prohibit both egress and ingress Internet connections, or just ingress connections.
