What is VPC and VPN, and How Do They Relate?

VPC and VPN are two essential components of cloud-based infrastructure that work together to provide secure and efficient access to resources.

It’s crucial to comprehend the architecture that underpins cloud-based apps as companies and organizations continue to transfer their activities to the cloud.

Virtual private clouds (VPCs) and virtual private networks (VPNs) are two essential elements of this system. Although the two concepts may seem similar, they have separate meanings, complementing one another to offer secure access to cloud-based resources.

In this post, we’ll delve more into VPC and VPN, examining what they are, how they vary, and how they relate to one another. We’ll also go through the reasons these technologies are crucial for companies to continue running secure and effective cloud-based operations.

What Is a VPC?

A virtual private cloud is a private cloud hosted in a public cloud, where you can enjoy all the benefits and resources of the private network but with high scalability and isolation levels between the private and virtual environment of the cloud.

Thus, while the public cloud supports a series of clients accessing its resources, the VPC reserves part of these resources for the individual use of a client. With this, the customer can have more control over the environment without the need to be in the public cloud.

VPC provisions cloud servers according to current business demands, expanding the data center without the need to invest in new equipment.

Benefits of VPC

Users can design isolated virtual networks and manage access to the resources located within them using a VPC.

Scalable Nature

Scalability is one of the main advantages of adopting a VPC. Users can design isolated virtual networks and manage access to the resources located within them using a VPC.

As a result, companies and organizations may design a cloud environment that’s specifically tailored to their needs and easily scaled up or down to meet those demands.

For instance, a corporation can immediately scale up its VPC resources to meet the increased demand if it notices a significant surge in traffic to its website or application.

In contrast, if traffic drops, the business can cut back on resources to cut costs. Without having to worry about managing and maintaining actual hardware, this scalability enables companies and organizations to tailor their cloud architecture to their needs.

Additionally, by eliminating the need for pricey physical infrastructure and enabling them to only pay for the resources they really utilize, the adoption of VPCs can assist enterprises and organizations in achieving cost reductions.

In general, a VPC’s scalability makes it a highly appealing choice for companies and organizations wishing to build a flexible, affordable, and managed cloud environment.

Greater Security

A VPC is always accompanied by a virtual private network that establishes the function of a lock on the private network, granting remote access to the VPC only to those who pass through the levels of security, authentication, and encryption imposed by the VPN.

In addition, industry-recognized cloud providers such as AWS have capabilities that extend the security levels of VPCs, as well as perform regular reviews and updates.

More Performance

With VPC, you can prioritize application traffic to optimize its performance, which helps to eliminate possible bottlenecks and network congestion.

Furthermore, as a cloud-hosted solution, VPC and its applications generally achieve significantly higher performance than those hosted on an on-premises server.

More Data Control

Although small, the risk of data crossing and mixing with data from other customers of a public cloud network exists. Therefore, with the VPC isolated from other customers and clouds, there’s more control over the data, making unforeseen events impossible.

Ease of Integration

With VPC, you can synchronize services with other VPCs, a public cloud, or on-premises infrastructure, forming a hybrid cloud.

Among the benefits of this integration, we can mention cost savings, a greater variety of technologies, data confidentiality, downtime backups, etc.

What Is VPN?

A virtual private network is a technology that allows users to establish a secure, encrypted connection to a network over the internet.

Companies commonly use VPNs to connect remote workers to their network, enabling access to resources that would otherwise be unavailable outside of the company’s physical location.

They’re also used to add an extra layer of security when accessing the internet from public WiFi networks, as VPNs encrypt all data transmitted between the user’s device and the network they’re connected to.

VPNs can be used to bypass geo-restrictions on content by allowing users to connect to servers in different locations around the world, making it appear as if they’re accessing the internet from a different country.

Overall, VPNs are an important tool for maintaining security and privacy when accessing the internet and connecting to networks remotely.

Benefits of VPN

  • Enhanced security—VPNs use encryption to protect the data transmitted between the user’s device and the network they’re connected to, making it difficult for hackers or third parties to intercept or access the data.
  • Privacy protection—By encrypting the data transmitted between the user’s device and the network, VPNs also help protect users’ online privacy by preventing ISPs, governments, or other entities from monitoring their online activities.
  • Remote access—VPNs allow users to access company resources or work remotely by securely connecting to a company’s network from a different location.
  • Bypass geo-restrictions—VPNs allow users to bypass geo-restrictions and access content that may be unavailable in their region by connecting to servers located in different countries.
  • Improved performance—Some VPNs can help improve internet performance by reducing latency, improving download speeds, and optimizing bandwidth allocation.

VPNs allow safe access to these VPCs because they establish a secure connection between the user’s device and the VPC.

How Do They Relate to One Another?

VPNs allow safe access to these VPCs because they establish a secure connection between the user’s device and the VPC.

Remote employees can securely connect to the VPC from locations other than the company’s headquarters thanks to this tunnel, which safeguards the data exchanged between the two.

In conclusion, VPCs and VPNs are crucial elements of a reliable and secure cloud infrastructure because they offer a secure environment for cloud-based resources and a safe way to access them from distant places.

To maintain safe and effective cloud-based operations, we can combine a VPN and VPC in a number of ways.

Making a site-to-site VPN connection between the VPC and the business’s physical location is a typical strategy. As if they were physically present in the office, remote workers are now able to securely and effectively utilize the resources in the VPC.

A client-to-site VPN connection is an alternative method that enables remote workers to securely connect to the VPC from their own devices without the requirement for a physical office presence.

Using a VPN gateway is a third option because it gives all remote workers a single point of access to the VPC. Due to the fact that all remote employees connect to the same gateway to access the VPC, this strategy might simplify maintenance and configuration.

In order to maintain secure and effective cloud-based operations, combining a VPN with a VPC is a crucial step. This combination enables distant workers to access resources safely and effectively while safeguarding critical data from unauthorized access.


All things considered, VPCs and VPNs are two essential components of cloud-based infrastructure that work together to provide secure and efficient access to resources.

While VPCs create a private network within a public cloud environment, VPNs offer secure access to those resources remotely. Both VPCs and VPNs provide numerous benefits, including enhanced security, privacy protection, remote access, and bypassing geo-restrictions.

As businesses and organizations increasingly rely on cloud-based infrastructure to support their operations, understanding the role of VPCs and VPNs will become increasingly important to maintain the integrity and security of digital operations.
