Amazon VPC (Virtual Private Cloud) Cloud Technologies
As you learned this week, a virtual private cloud (VPC) enables you to launch resources into a virtual network that you’ve configured and gives you full control over those resources. That provides a level of security over a public cloud when you need to control your resources and sensitive data over a virtual infrastructure. But VPCs also have drawbacks, including increased configuration complexity.
Look ahead to this week’s “Design of a VPC” activity in AWS Academy Module 5: Networking and Content Delivery (Located in the Cloud Foundations eBook), where you will design a VPC. Address the following questions in your discussions. Be sure to answer all questions in your initial post and respond to two posts by your classmates.
Question 1: What are the components of an Amazon VPC?
Question 2: What is the default VPC and what are its advantages?
Amazon VPC (virtual private cloud) Cloud Technologies
Components of an Amazon VPC
Using Amazon VPC, clients can establish a sensibly isolated virtual section, setting, or AWS Cloud network. They can launch their AWS services and resources in a virtual network defined by the client as per business needs and use case. The customers can define and choose IP addresses or IP address space from the ranges of VPC. Amazon VPC is formed of numerous different networking components. Some of them include, first, subnets. These are classic subnets or sub-networks in any typical on-premise data center. They can be private or public, or VPC may have a combination of both. It’s a client-defined VPC’s IP address variety segment to place inaccessible resources in the groups. The second component is Elastic Network Interfaces. ENI is a reasonable networking component in VPC, signifying an effective network card. Route table is the third component of Amazon VPC. It is used for routing purposes. It controls where the network traffic must be directed and controls routing for subnets. Internet gateway comes in as the fourth component of Amazon VPC. The Internet gateway is Amazon router on Amazon cloud’s IT network and infrastructure for customers’ AWS assets to fix the external world or the network like public Internet. It’s a connection on the Amazon VPC side to the public Internet. The fifth component is Elastic Internet Protocol (IP) addresses (EIP). EIP is a public, fixed IPv4 address designed for dynamic cloud computing. Besides, Network Address Translation (NAT) Gateway is also an Amazon VPC component. It’s an Amazon service fully managed by AWS for client’s resources to be placed in a private subnet to access the outer world or public Internet. Its service is highly accessible.
Default VPC and its Advantages
Default VPC is a rationally isolated virtual network or a section to deploy or host the customer’s services or resources in the AWS cloud (Srinivasan, Ravi & Raj 2018). It is automatically created for the customer’s AWS version; the first time client provisions Amazon Elastic Compute Cloud resources. Whenever customers present an instance without subnet-ID identified, their instance may be launched in their default VPC. It’s ready to use the VPC evading to form and configure the client’s VPC. If a client deletes default VPC for his account, he or she might experience problems.
Customers can instantly launch Amazon EC2 instances in their default VPC. Therefore, it saves time, it’s convenient, easy enough to start using VPC, hassle-free, numerous other AWS resources and services can be formed, run, and applied in customer’s default VPC. It helps the clients get their AWS services, and resource creation and deployment began quickly. The default VPC affords easiness information of AWS resources in them. It’s simple. It provides availability of access to the Internet by default. Clients get advanced networking functionalities of the Amazon VPC for resources thrown in default VPC. The clients can change- security group membership enthusiastically, multiple IP addresses and network interfaces, and the security group egress filtering without the client having to openly and physically create VPC and launch the instances and the rest of resources in VPC.
