In today’s rapidly evolving digital landscape, the modernization of enterprise networks is more crucial than ever. As businesses strive to stay competitive, the demand for networks that can provide seamless, cloud-like experiences is growing. This includes ease of management, abstraction of infrastructure, automation, and scalability. However, achieving this requires a strategic approach to network modernization, particularly in a world where network gear is increasingly commoditized, and software features and automation capabilities often dictate purchasing decisions.
The Shift Towards Software-Driven Networks
Gone are the days when enterprises relied solely on hardware capabilities to differentiate their networks. Today, the focus has shifted to software features that enable turnkey automation, enhance security, and simplify network management. This shift is driven by several factors, including the proliferation of Internet of Things (IoT) devices, the rise of hybrid work environments, and the increasing adoption of Software-as-a-Service (SaaS) applications.
As businesses continue to embrace these trends, they require networks that can adapt to dynamic traffic patterns, provide secure access to a growing number of endpoints, and scale to meet future demands. This need for agility and adaptability is pushing organizations to reevaluate their network infrastructure and explore new solutions that align with their evolving needs.
The Importance of Zero Trust in Modern Networks
In the pursuit of a secure network environment, many organizations are adopting Zero Trust Architecture (ZTA). Unlike traditional security models that rely on perimeter defenses, Zero Trust assumes that threats can come from anywhere—inside or outside the network. Therefore, every access request must be verified, regardless of its origin.
However, Zero Trust is not just a technology or tool; it is a comprehensive approach that extends beyond the network to include endpoints, identities, applications, and more. Implementing Zero Trust requires a holistic strategy that considers the unique needs of your organization and the various components of your network.
For instance, in heterogeneous environments where you have a mix of legacy equipment, IoT devices, and newer technologies, enforcing security policies and microsegmentation may need different approaches depending on the use case. This underscores the importance of developing a well-rounded ZTA strategy that addresses all aspects of your enterprise network.
Navigating the Complexities of Network Modernization
Modernizing your network is no small feat. The goal is to deploy and future-proof an infrastructure that is tailor-made for your organization’s needs, rather than relying on a generic solution that requires frequent ad hoc changes and workarounds. This process involves several key steps:
- Document Endpoint Connectivity Requirements: Begin by itemizing the connectivity requirements of all endpoints within your network. In environments with a mix of legacy and modern devices, you may need fit-for-purpose Access Points (APs) and LAN switches. Ensure that your network infrastructure can handle the expected increase in traffic, particularly in the access-core-edge segments, to prevent bottlenecks.
- Manage Your Network as a Platform: Treat your network as a platform, especially if you want to avoid vendor lock-in. This involves using different vendors for each tier or scope of your network while managing it as a single entity. However, avoid using networking gear from different vendors for the same role, as this can add complexity and hinder automation efforts.
- Establish the Most Appropriate Architecture: Take a holistic view of your enterprise network to determine the best architecture for your needs. This includes evaluating core networks, WAN edge, branches, and wireless/wired LANs. Simplify your architecture where possible, and choose a topology that matches your traffic patterns and connectivity requirements.
- Implement Network Segmentation: Network segmentation is a critical component of Zero Trust. Implement macrosegmentation by creating new Virtual Routing and Forwarding (VRFs) at the network core and migrating VLANs/subnets accordingly. Determine whether security policies and microsegmentation will be enforced at the network or endpoint level, depending on your environment.
- Evaluate the Market and Choose Vendor(s): Avoid like-for-like replacements when refreshing your network hardware. Instead, perform proof-of-concepts (POCs) with different vendors to identify the most suitable products that meet your current and future requirements. Consider both hardware-based and software-based capabilities during your evaluation.
- Deploy and Validate New Network Infrastructure: When deploying new infrastructure, start with the least critical sections of your network. This allows you to familiarize yourself with the new products, validate user experiences, and learn from initial deployments before rolling out changes to more critical environments.
- Automate Day 2 Network Operations: Leverage network platforms to automate day-to-day operations such as device provisioning, configuration management, and software upgrades. This reduces the burden on your IT team and ensures consistency across your network. In complex environments, consider using AI- and ML-enabled features for advanced automation capabilities.
Conclusion: Future-Proofing Your Enterprise Network
Network modernization is a continuous process that requires careful planning and execution. By understanding your connectivity requirements, evaluating your current and future needs, and leveraging modern technologies and architectures, you can build a network that is not only resilient but also adaptable to the ever-changing demands of the digital age.
Whether you are looking to implement Zero Trust, manage your network as a platform, or simplify your architecture, the key is to take a strategic approach that aligns with your organization’s goals. In doing so, you can future-proof your enterprise network, ensuring it remains a valuable asset that supports your business objectives for years to come.
