What Is A Virtual Cloud Network?

If you’re planning to build a virtual cloud network, there are several factors you need to take into account. These factors include CIDR range, NSX, and CIDR block size. Learn about these elements to help you decide which network is best for you. You can read our virtual cloud networking guide if you’re still unsure. You’ll learn how to create a VPC and its benefits and disadvantages.

NSX

The Virtual Cloud Network supports distributed applications while maintaining high availability. It supports a mix of infrastructures, enabling it to be used across data centers and branches. NSX is a logical evolution of the traditional data center network. NSX Data Center and NSX Federation help you embrace multiple cloud environments with a consistent strategy. In addition, they offer advanced security features that enable you to protect the virtual network while maintaining network agility.

CIDR range

The CIDR range of a virtual cloud network (VCN) specifies the IP address ranges used by its instances. The range must span all CIDR blocks in the VPC. If the CIDR ranges overlap, instances on different VCNs cannot communicate. This rule applies to all VCNs, not just the most common ones. Each VPC can have as many as five CIDR blocks per zone.

To create a VCN, an Oracle Cloud user must provide the CIDR range. This is a list of IP addresses available in the VCN. To use more than one VCN, a VCN must peer with other SDNs and Virtual Cloud Networks. Once the VCN is created, it is possible to modify the CIDR range. However, it is essential to note that the CIDR range cannot overlap with any other virtual cloud network’s CIDR block.

Benefits

Virtual cloud networks offer several benefits to enterprises. For example, they enable secure global network access, provide high-end monitoring of servers, and control traffic flow between interconnected servers. They also offer enhanced security features and visibility to users. Moreover, these networks promote multiple network functions in the cloud. Therefore, they are an essential part of any enterprise network. To learn more about the advantages of virtual cloud networks, keep reading. Until now, no one has fully understood the benefits of these networks.

Virtual cloud networks reduce the number of physical pieces needed in traditional networks. For example, when building a conventional network, an organization must install hardware components like Ethernet cables and modems. By using virtual cloud networks, however, these components do not need to be installed on the premises. Instead, organizations can arrange for all data provisioning to occur in the cloud. Further, you can expand their network when the cloud provider needs it. By utilizing the power of virtual cloud networks, enterprises can scale up their infrastructure without compromising efficiency.

Costs

When migrating your data between virtual clouds, you need to consider your data migration strategy to minimize your egress billing to your CSP. Using a secure private network is the most effective way to mitigate this riskā€”CSPs reward secure private networks with lower egress bills. Microsoft Azure ExpressRoute and AWS Direct Connect are two common ways to create secure private networks. Here are the costs of each.

IT infrastructure costs are typically about two to three percent of capital expenses, including software, hardware, and management. To determine the costs of your network, you can do a thorough IT infrastructure audit. Direct costs include software, hardware, and staff; indirect costs include physical building and maintenance. Other costs may be less obvious, such as lost productivity, customer dissatisfaction, and ruined reputation.
