Virtual Private Cloud

Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you'vedefined. This virtual network closely resembles a traditional network that you'd operate inyour own data center, with the benefits of using the scalable infrastructure of AWS.

A gateway connects your VPC to another network. For example, use an internet gatewayto connect your VPC to the internet. Use a VPC endpoint to connect to AWS services privately, without the use of an internet gateway or NAT device.

A virtual private cloud (VPC) is an on-demand configurable pool of shared resources allocated within a public cloud environment, providing a certain level of isolation between the different organizations (denoted as users hereafter) using the resources. The isolation between one VPC user and all other users of the same cloud (other VPC users as well as other public cloud users) is achieved normally through allocation of a private IP subnet and a virtual communication construct (such as a VLAN or a set of encrypted communication channels) per user. In a VPC, the previously described mechanism, providing isolation within the cloud, is accompanied with a virtual private network (VPN) function (again, allocated per VPC user) that secures, by means of authentication and encryption, the remote access of the organization to its VPC resources. With the introduction of the described isolation levels, an organization using this service is in effect working on a 'virtually private' cloud (that is, as if the cloud infrastructure is not shared with other users), and hence the name VPC.

VPC is most commonly used in the context of cloud infrastructure as a service. In this context, the infrastructure provider, providing the underlying public cloud infrastructure, and the provider realizing the VPC service over this infrastructure, may be different vendors.

IBM Cloud launched IBM Cloud VPC[5] on 4 June 2019, provides an ability to manage virtual machine-based compute, storage, and networking resources. [6] Pricing for IBM Cloud Virtual Private Cloud is applied separately for internet data transfer, virtual server instances, and block storage used within IBM Cloud VPC. [7]

Google Cloud Platform resources can be provisioned, connected, and isolated in a virtual private cloud (VPC) across all GCP regions.[8] With GCP, VPCs are global resources and subnets within that VPC are regional resources. This allows users to connect zones and regions without the use of additional networking complexity as all data travels, encrypted in transit and at rest, on Google's own global, private network. Identity management policies and security rules allow for private access to Google's storage, big data, and analytics managed services. VPCs on Google Cloud Platform leverage the security of Google's data centers.[9]

A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. A VPC gives an enterprise the ability to define and control a virtual network that is logically isolated from all other public cloud tenants, creating a private, secure place on the public cloud.

VPCs achieve high levels of security by creating virtualized replicas of the security features used to control access to resources housed in traditional data centers. These security features enable customers to define virtual networks in logically isolated parts of the public cloud and control which IP addresses have access to which resources.

A virtual private network (VPN) makes a connection to the public Internet as secure as a connection to a private network by creating an encrypted tunnel through which the information travels. You can deploy a VPN-as-a-Service (VPNaaS) on your VPC to establish a secure site-to-site communication channel between your VPC and your on-premises environment or other location. Using a VPN, you can connect subnets in multiple VPCs so that they function as if they were on a single network.

A virtual private cloud (VPC) is a private cloud computing environment contained within a public cloud. Essentially, a VPC provisions logically isolated sections of a public cloud in order to provide a virtual private environment.

A private cloud consists of infrastructure dedicated completely to a single organization. Usually, an organization will buy the cloud infrastructure, install the software, and hire an IT management team. In this case, the organization owns everything from top to bottom.

On the other hand, a VPC runs on shared infrastructure just like a public cloud. However, a VPC offers a level of isolation between the cloud customers sharing resources. This layer of isolation is achieved through a private IP subnet or a virtual local area network (VLAN).

VPC helps you build an isolated network environment based on Alibaba Cloud including customizing the IP address range, network segment, route table, and gateway. In addition, you can connect VPC and a traditional IDC through a leased line, VPN, or GRE to provide hybrid cloud services.

A virtual private cloud (VPC) is the division of a service provider's public cloud multi-tenant architecture to support private cloud computing. VPCs are, therefore, a private cloud hosted within a public cloud architecture. This model enables an enterprise to achieve the benefits of private clouds (such as more granular control over virtual networks and an isolated environment) while using public cloud resources.

VPCs are a public cloud offering that lets an organization establish its own private cloud-like computing environment on shared public cloud infrastructure. A VPC runs on shared infrastructure like a public cloud does but isolates customers from each other. VPC resources are then reserved for use for each specific customer. The isolation creates a private and more secure public cloud.

The terms private cloud and virtual private cloud are sometimes used incorrectly as synonyms. There is a distinct difference -- in a traditional, on-premises private cloud model, an enterprise's internal IT department acts as a service provider and the individual business units act as tenants. With a VPC, a public cloud provider acts as the service provider, and the cloud's subscribers are the tenants.

In a virtual private cloud model, the public VPC provider is responsible for ensuring that each cloud customer's data remains isolated from every other customer's data both in transit and inside the cloud provider's network. This is accomplished through the use of security policies requiring some -- or all -- of the following elements: by allocating a unique virtual local area network (VLAN) to each customer, by providing a subnet or a virtual private network (VPN).

Connecting to your Anypoint VPC extends your corporate network and allows CloudHub workers to access resources behind your corporate firewall.You can connect on-premises data centers through a secured VPN tunnel or a transit gateway attachment, or connect a private AWS VPC to your Anypoint VPC through VPC peering or AWS Direct Connect.

Earlier, IT companies relied on the private cloud since they were worried about their data. However, as advanced cloud security protocols emerged, many cloud users now lean towards the public cloud for savings and scalability.

You can consider the public cloud as your dorm room, where you have to share the accommodation with other students. But, a VPC is equivalent to condominiums where you've got your own secure place within a public premise.

Also, for the cloud platform users who need robust customization and total control over their cloud apps, a VPC is the ideal solution since their cloud assets stay separated from other cloud users. It's worthy to note that VPC user-induced modifications don't interfere with non-VPC users.

Though all the digital assets of a VPC user exist on a public cloud, only specific IP addresses can access those. The user has exclusive control over access permission, and if required, they can allow a particular group of public cloud users to access their apps or websites.

Online design tools like Canva or Figma are the ideal examples. These apps utilize VPC to distinguish the access levels of technicians and users. Registered public users can access the tool for designing purposes, whereas the tool developers will have exclusive access to the cloud app that controls all the end-user functions.

The cloud resources or logical instances of a VPC don't mingle with the rest of the public cloud. The cloud computing vendor utilizes several virtual and physical mechanisms to ensure the complete isolation of logical instances.

The data operations within a VPC follow a three-tier architecture, and they require their own subnet. Therefore, there are separate IP address ranges for each tier. The application layers also get their own access control list (ACL). Hence, you can control user access to different segments of your cloud asset.

The virtual private cloud works on the principle of the abstraction layer that you can create on top of a physical server. Now, you can divide the abstraction layer into many virtual machines (VMs) with dedicated software and computational power.

Similarly, a VPC creates a virtualized layer on public cloud hardware and reserves a part of the processing capability, memory, and storage for itself. Depending on the capacity of the original public cloud infrastructure, you can create multiple VPCs.

That's just keeping the VPC user's data and data processing isolated from other public cloud users. VPCs also ensure that the data in transit is distinct and secured from other users. You can achieve this by utilizing the following networking components:

VPCs consist of several private IP addresses that you can't access from the public-facing internet if you don't have access permissions. Therefore, data transmitted through these IP addresses aren't easy to intercept.

In a VPC, the data transmission between cloud assets or nodes occurs through the public cloud network. However, VPCs utilize the VPN to encrypt the data when it transmits through shared resources like routers, switches, etc. 041b061a72
