Organizations who prefer not to employ pooled cloud resources have turned to the private cloud environment when seeking a cloud communications solution. Public cloud systems have been ruled out because of the prospect of exchanging data with other firms (maybe even competitors).
Moving to a VPC allows businesses to create a safe and secure environment for enterprise cloud applications and backup and disaster recovery alternatives that can be deployed quickly. Additionally, The VPC gives companies the ability to provide improved client experiences.

For these reasons, Cloud architects are projected to be the second most in-demand tech job in 2021.
What is a Virtual Private Cloud?
A virtual private cloud (VPC) is a private cloud computing platform within a public cloud environment. Take, for example, a café full of people and where a table has been reserved. Only diners who have made a reservation are allowed access to the table. This reserved table functions as a virtual private cloud within the ‘hosted’ (public) cafe.
While they may sound similar, “private cloud” and “virtual private cloud” are not interchangeable. A single-tenant private cloud is a service that is only available to one company. A private cloud within a public cloud is known as a virtual private cloud.
A private cloud is powered by specialized infrastructure found on-premises, in a dedicated off-premises data centre, or a managed cloud provider. Control and exclusivity are two advantages of a private cloud. There are no nearby neighbors with whom to share hosted resources.
Working of VPC
A virtual private cloud (VPC) is a hybrid cloud platform that blends the benefits of private and public cloud environments into one. VPCs are virtual private clouds that run on a public or shared infrastructure.
The public cloud infrastructure provider in a virtual private cloud arrangement is responsible for ensuring that a private cloud customer’s data is kept separate from other customers, both in transit and within the cloud provider’s network. This is accomplished by employing security policies that demand at least some elements.
VPC allows you to quickly create a virtual network architecture into which AWS instances can be deployed. Each VPC specifies the requirements for your AWS resources, including the below elements.
Elements of VPC
- IPv4 and IPv6 address blocks
- Subnet creation
- Route tables
- Internet connectivity
- Elastic IP addresses (EIPs)
- Network/subnet security
- Additional networking services
Why is Virtual Private Cloud Gaining Popularity?
As per Gartner, a few trends in cloud computing are expanding the breadth of cloud products and capabilities, boosting growth across all public cloud services industry areas. Cloud ubiquity, regional cloud ecosystems, sustainability and carbon-intelligent cloud, and automated programmable infrastructure from cloud infrastructure and platform service (CIPS) providers are among these developments.
However, the private cloud has grown in popularity due to the advantages it provides over the public cloud. Regardless of your sector, a private cloud offers benefits such as flexibility, cost savings, security, and control. These advantages are especially beneficial to firms with predictable workloads or customization requirements and those in regulated industries.
The following reasons motivate cloud architects to grasp how virtual private clouds (VPCs) work so that they can handle the difficulties of cloud adoption.
-
Better Performance and Agility
Virtualization technology underpins all sorts of cloud computing, and VPC is no exception. Most servers are underutilized, and virtualization improves resource efficiency in VPC. This allows workloads to be moved to a different physical server when service demands change. Alternatively, the resources dedicated to a certain server can be modified to match the changing demands of any individual application.
-
Improved Security
According to a survey conducted by security firm Ixia, 90% of IT pros are concerned about data and application security in public clouds. While any cloud system requires strong antivirus and firewall protection, a VPC is hosted on a limited number of physical workstations, making physical security easier to maintain. VPC providers frequently have more resources for updating and supporting infrastructure.
-
Increased Flexibility
A successful migration is crucial to realizing the desired benefits of the new ecosystem. Because we cannot customise the public cloud to serve any application, organizations migrating from a traditional on-premise system typically find it challenging to deploy their workloads. Additionally, migrations to private clouds have a greater success rate than public clouds, leading to a reduced TCO.
-
Reduced Costs
VPC’s flexibility and superior resource usage can help businesses ensure application performance while also saving money by maximizing server utilization. For some businesses, a VPC is not only less expensive than an on-premise environment, but it may also be less expensive than a public cloud environment. In addition, 41% of IT decision-makers believe that their private cloud is less expensive than a public cloud.
-
Regulatory Compliance
Private cloud environments’ security and control benefits have contributed to their popularity among enterprises with compliance concerns. Another argument is that service providers who supply hosted private clouds can assist with critical regulatory requirements such as HIPAA and PCI compliance. Some businesses may have no choice but to use a private cloud to benefit from cloud computing while remaining compliant with regulations.
