What is Virtual Private Cloud VPC

Byadmin

Cloud computing has come a long way from its birth. All started as a public cloud then evolved as private cloud and then hybrid cloud, etc., In this row Virtual Private Cloud has added up and become a favorite choice for many businesses. Let’s discuss what it is in this blog. 

What is Virtual Private Cloud? 

“VPC is a cloud in the cloud” 

Yes! Virtual Private Cloud is the Cloud environment built inside the public cloud to provide users the comfort of Public Cloud and the security of private cloud. VPC is a superior combo of confidentiality and security. In a Public cloud environment, many organizations sharing the space with the cloud but the data has not shared. Yet We can’t deny the security threads associated here. 

Virtual Private Cloud acted as a separate space assigned for a particular organization within a public cloud to ensure security. 

 For better understanding, consider a restaurant as a public cloud, anyone who comes in the restaurant can sit anywhere.  Like sharing the space with the public cloud. Reserving a table is like Virtual Private Cloud, only you can access that space 

Key Features of VPC 

VPC Network 

One can easily configure VPC within their network. Once done, it automatically fixes things like virtual topology, prefix rangers and network policies. 

 VPC flow logs 

 Flow logs are intended to capture insights like the traffic going to and from the network. It helps in monitoring, security analysis and forensics. 

 VPC Peering 

 Peering lets you to configure private communication over the same of different organization based on your wish. 

 Shared VPC 

 Set up a VPC network so that it can be shared by numerous of your company’s projects. Firewalls and connectivity routes are centrally regulated. Your developers simply join to a shared private network where they can interact while working on their respective projects with independent billing and quotas. 

VPC Service Controls  

 Set up secure connections between cloud resources deployed across on-premises and cloud deployments using VPC networks. Take advantage of the fully managed storage and data processing capabilities while maintaining the privacy of sensitive data.

How Virtual Private Cloud Works? 

It is important to understand how Virtual public cloud is isolated from the public cloud and the key technologies within it. VPC is a great isolation technology. Tunneling technology is the fundamental thing used here. Each VPC is identified with a unique tunnel id. 

Data from the specific tunnel is encapsulated and transmitted to the respected physical server via ECS. Each and every data transmitted through ECS is tagged by a specific tunnel id.  

Some indispensable technologies with VPC 

Subnets 

 A subnet is a set of IP addresses that are reserved within a network so that they are not accessible to all users, thus segmenting the network into private and public areas. These IP addresses are private in a VPC, as opposed to normal IP addresses, which are accessible via the public Internet. 

 VLAN 

 A local area network, or LAN, is a collection of computing devices connected to one another directly rather than over the Internet. A virtual LAN is a VLAN. Similar to a subnet, a VLAN is a method of dividing a network, but the division occurs at a different layer of the OSI model. 

 VPN 

 A virtual private network (VPN) overlays a private network on top of a public network using encryption. VPN traffic travels through routers, switches, and other publicly accessible Internet infrastructure, but it is scrambled and hidden from view.

Top VPC Providers 

Big sharks that offer Virtual Private Cloud Services are 

Amazon VPC 

With the help of Amazon Virtual Private Cloud (Amazon VPC), you may start launching AWS resources into a defined virtual network. This virtual network has the advantages of using the scalable infrastructure of AWS while closely resembling a conventional network that you would operate in your own data center. 

Azure VPC 

Microsoft is the tech giant behind Azure VPC. They provide sophisticated topology options to users you can make use of it if you are on Azure environment. 

IBM VPC 

A virtual network connected to your customer account in IBM Cloud is called a Virtual Private Cloud (VPC) on IBM Cloud. You can control your computing, storage, and networking resources by using a virtual private cloud. In logically isolated areas of the IBM Cloud, you can run and support your mission-critical, cloud-tolerant, and cloud-native applications by using IBM Cloud VPC to establish and manage a virtual network. 

 Google VPC 

In Google Virtual Public Cloud, resources can be provided, connected, and separated across all geographies and regions. On Google’s worldwide private network, data is encrypted both in transit and at rest, allowing users to connect zones without having to complicate the network. 

Benefits of Virtual Public Cloud 

Flexibility: You have no limitations and restrictions; you can enlarge the space based upon your own wish 

Hybrid Cloud Deployment: The overall working function resembles the hybrid cloud environment thus it is a kind of ready-made Hybrid cloud. 

Efficiency: The performance of the applications will get improved in all the aspects. 

Enhanced Security: The data which is considered as crucial can be stored in the VPC, thus no more security threads.
