What is VPC?

VPC provides you the flexibility to scale and control how workloads connect regionally and globally. You will have global access to your VPCs without needing to replicate connectivity or administrative policies in each region when you connect your on-premises or remote resources to GCP. A VPC is a public cloud capability that gives you the ability to define and control isolated virtual networks and then deploy cloud resources into those networks.

A VPC is also a cost-effective way to expand your business presence into a public cloud instead of recreating the infrastructure you have already built onsite. It is a great option for companies who have large workloads and are looking to test new services.

Benefits of Virtual Private Cloud: 

The following diagram shows the benefits of VPC:

1. Customization: Network performance, storage performance, and hardware performance can be specifically customized to the client’s private cloud.
2. Security: Since private clouds are built around one single business, the data storage, network, and hardware can be specifically designed around the security needs of your business. It cannot be accessed by any other client or company in the same building or data center.
3. Hybrid Deployments: If a server is asked to run at a very high speed then it can then be integrated with a private cloud and can then become a solution for dedicated servers and virtual servers which cannot be accomplished through a public cloud.
4. Compliance: Compliance is much easier to accomplish because each network and storage configuration is based around one single client. This makes it much easier to monitor their security and compliance needs.
5. Application Performance: More traffic and congestion on the Internet can disrupt or slow down your application traffic. Even if you have sized your network for peak times, inbound congestion could hamper application performance and make applications run slow. With VPC, the cloud resources are routed through the corporate MPLS based WAN. Thus, traffic with a high priority can be delivered and marked respectively.
6. Effective bandwidth: Your company will be paying twice for bandwidth. First is to pay for the primary WAN connection and second for the Internet. Cloud access to on-demand resources.

Private clouds are not available on a pay-as-you-go basis because they are hardware that requires a lot of observation. Private storage clouds are commonly used by mid to large-size businesses where compliance and security is a factor. It makes it much easier for them to maintain their credibility as a business and keep all of their data secure. It can accomplish many great things for your business especially if it is a growing one.

Uses for Virtual Private Cloud:

For building simple and complex architectures using VPC, like:

1. Connecting GCP-hosted or externally-hosted databases to Google’s unique machine learning services, by creating a Virtual Private Cloud with subnets and Virtual Private Network access.
2. Hosting globally distributed multi-tier applications, by creating a Virtual Private Cloud with subnets.
3. Create backup Google Cloud Platform compute capacity, then revert when the incident is over. Disaster recovery with application replication.
