VPC

A private or private cloud VPC is a cloud computing delivery model that provides computing resources such as servers, storage, and networking equipment within an organization or enterprise that is constrained by a network. Various IT processes are placed in the virtual environment to optimize loads on physical devices and to protect critical information. In this article we will analyze in detail: why VPC is needed, what it is used for and how a company's business sphere influences the choice of the service.

Main features of VPC

1. Isolation:
   The VPC is isolated from other virtual networks and resources within the cloud provider. This is achieved through the use of virtual machines, routing, and other networking technologies.
   
2. Network customization:
   Users can create their own subnets, define IP address ranges, set routing rules, and configure routing tables.
3. Firewall:
   Network ACLs (Access Control Lists) and group security policies can be used to protect resources within the VPC. These tools help control and filter incoming and outgoing traffic.
4. Connectivity:
   VPC allows you to connect isolated networks to the Internet, to other VPCs, or to the LAN through secure communication channels such as VPN or Direct Connect.
5. Resource Flexibility:
   Within a VPC, you can run and manage a variety of resources such as virtual machines (EC2), databases, storage, and other cloud provider services.

Examples of VPC use

• Testing and development:
  Isolated VPC environments are ideal for application development and testing without the risk of impacting production resources.
  
• Hybrid clouds:
  VPC can be used to create hybrid clouds by combining on-premises resources with cloud resources through secure channels.
• Regulatory and legal compliance:
  VPC enables you to meet standardized security and privacy requirements by isolating and controlling network resources.

Advantages of VPC

High levels of control and security - VPC owners can fine-tune all aspects of the network, ensuring a high level of data protection.

Scalability - VPC easily scales as needed, allowing organizations to adapt to changes in workload and requirements.

Segmentation and Isolation - The ability to segment network resources and isolate them by various criteria, such as by department, project or access levels

Examples of cloud providers offering VPC

Serverspace (Serverspace VPC)
Serverspace provides users with a virtual private cloud with benefits such as:

• Pay-as-you-Go
  There are no fixed payments, payment is deducted every 10 minutes only for used servers.

• 1 Gbps channel width
  The bandwidth allows you to run large-scale projects with a lot of traffic.
• SLA 99.9%
  Guarantee of continuous availability of servers within SLA and compensation in case of its violation.

Amazon Web Services (AWS):
Amazon Virtual Private Cloud (Amazon VPC) gives users full control over their virtual network environment, including selecting an IP address range, creating subnets, configuring routes, and configuring firewalls.

Google Cloud Platform (GCP):
Google Cloud VPC offers a global virtual network that allows you to create and manage isolated network resources across GCP regions.

Microsoft Azure:
Azure Virtual Network (VNet) provides the ability to create isolated network environments in the Azure cloud.

VPC components

• Subnets:
  Divide the VPC's IP address space into smaller segments for organizing and managing resources.
• Internet Gateway:
  Allows the VPC to connect to the Internet, providing access to and from external resources.
• NAT Gateways (Network Address Translation Gateway):
  Allow resources on the VPC's private subnets to access the Internet without being able to accept incoming connections from the outside.
• VPN Connections:
  Allow VPCs to connect to local networks through encrypted tunnels for secure data transfer.
• Route Tables:
  Define rules for routing traffic between subnets inside and outside the VPC.

And you can work in an isolated and secure environment with all the benefits of the public cloud with Serverspace!
