Virtual private cloud in Cloud Computing

What is VPC ? 

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.

VPC Isolated Protocol within a Public Cloud

Subnet: A subnet is a range of IP addresses within a network that are reserved so that they're not available to everyone within the network. In a VPC these are private IP addresses that are not accessible via the public Internet, unlike typical IP addresses, which are publicly visible.

VPN: A Virtual Private Network uses encryption to create a private network over the top of a public network. VPN traffic passes through publicly shared Internet infrastructure – routers, switches, etc. – but the traffic is scrambled and not visible to anyone.

Ex: A VPC will have a dedicated subnet that is only accessible by the VPC customer. This prevents anyone else within the public cloud from accessing computing resources within the VPC – effectively placing the "Reserved" sign on the table. The VPC customer connects via VPN to their VPC, so that data passing in and out of the VPC is not visible to other public cloud users.

Benefits of using VPC

Each VPC’s main features readily translate into a benefit to help your business achieve agility, increased innovation, and faster growth.

• Flexible business growth: Because cloud infrastructure resources including virtual servers, storage, and networking can be deployed dynamically, VPC customers can easily adapt to changes in business needs.
• Satisfied customers: In today’s “always-on” digital business environments, customers expect uptime ratios of nearly 100%. The high availability of VPC environments enables reliable online experiences that build customer loyalty and increase trust in your brand.
• Reduced risk across the entire data lifecycle: VPCs enjoy high levels of security at the instance or subnet level, or both. This gives you peace of mind and further increases the trust of your customers.
• More resources to channel toward business innovation: With reduced costs and fewer demands on your internal IT team, you can focus your efforts on achieving key business goals and exercising core competencies.
