Best On-Premises Network Virtualization Software of 2025

Achieve flexible resource management through the implementation of automation guided by standardized policies for data center operations. By ensuring consistent policy administration across various on-premises and cloud environments, you can enhance security, governance, and compliance. This approach guarantees business continuity, effective disaster recovery, and secure networking under a zero-trust security framework. Moreover, it transforms Day 2 operations into a proactive model that automates troubleshooting, root-cause analysis, and remediation tasks. This not only optimizes performance but also allows for single-click access to facilitate automation and centralized control. Extend your on-premises ACI networks seamlessly to remote sites, bare-metal clouds, and colocation facilities without the need for additional hardware. Cisco's Multi-Site Orchestrator plays a crucial role by offering provisioning, health monitoring, and management of Cisco ACI networking policies, among other functionalities. This comprehensive solution streamlines network connectivity, maintains uniform policy management, and simplifies operations across various multicloud settings, ultimately enhancing operational efficiency and scalability for enterprises.

Customers create Virtual Cloud Networks (VCNs) that cater to their unique IP address requirements for workloads and can segment a VCN into smaller ranges through private or public subnets or allocate numerous IP addresses to a single VCN. They can also extend their existing on-premises networks and interconnections by utilizing virtual routers and gateways. Through peering gateways, customers can establish connections between different VCNs within the same tenancy or securely link to other tenancies. FastConnect offers customers the opportunity to establish direct, private, high-bandwidth connections to their Oracle Cloud Infrastructure (OCI) virtual cloud network, allowing them to choose their desired port speed based on data volume and pay a stable, low monthly fee, unlike other providers who charge based on data transferred, leading to unpredictable costs. Additionally, OCI incorporates a security-first architecture that safeguards customer tenancies by employing isolated network virtualization, which is a vital component designed to thwart malware using a custom-built SmartNIC for network isolation and virtualization. This innovative approach not only enhances security but also optimizes network performance and reliability for customers.

Azure Network Function Manager delivers a standardized management interface for pre-validated mobile network functions, facilitating the implementation of private LTE and 5G solutions. This service also supports a smooth cloud-to-edge integration for Azure Marketplace network functions, including SD-WAN. You can deploy secure private 5G and LTE mobile networks on-site, with the ability to quickly set them up from various mobile packet core network function partners directly through the Azure portal. These networks are designed to provide extremely low latency, making them ideal for real-time edge applications, such as augmented reality, virtual reality, and industrial robotics. Managing and deploying SD-WAN and VPN solutions at the edge is made simple, thanks to a diverse ecosystem of partners. Additionally, for a comprehensive hybrid experience, Azure Marketplace allows you to select from a list of pre-validated network functions, ensuring compatibility with the network functions utilized in Azure and Azure Virtual WAN, which further enhances the operational reliability with Azure Stack Edge. This integration not only streamlines deployment but also enhances the performance of critical applications in various industries.

Utilize Azure ExpressRoute to establish secure private links between Azure data centers and your local infrastructure or colocation setups. Unlike standard internet connections, ExpressRoute pathways do not traverse the public internet, providing enhanced reliability, quicker speeds, and reduced latencies. This approach can lead to considerable cost savings when transferring data between your on-site systems and Azure. Moreover, ExpressRoute enables you to seamlessly connect and expand the compute and storage capabilities of your current data centers. With its high throughput and rapid response times, Azure will integrate seamlessly as an extension of your existing environments, allowing you to leverage the scalability and economic advantages of the public cloud while maintaining optimal network performance. This combination ensures that you can efficiently manage workloads and data transfer without compromising on speed or reliability.

Designed for vertical integration and ready to scale, this solution introduces hyper-scaler agility to mainstream enterprises. It provides software that benefits both developers and operators equally, enabling project launches within minutes of system activation. With per-tenant isolation, you maintain complete control over networking, routing, and firewalls via VPC and advanced network virtualization features. As your deployment grows, network services seamlessly scale, removing the usual bottlenecks that hinder performance. Elastic compute resources can be allocated from a unified infrastructure pool, ensuring compatibility with the development tools you are already familiar with. Moreover, it offers a high-performance, persistent block storage service that allows for adjustable capacity and IOPS for each volume. Transitioning from rack installation to developer readiness can be achieved in just hours, a significant reduction compared to the weeks or months typically required. This solution occupies only two-thirds of the space needed for conventional on-premises infrastructure, making it an efficient choice. Additionally, you can utilize familiar management tools through our integrations with Kubernetes and Terraform, streamlining operations and enhancing productivity even further.
