Frequently asked questions
What is network infrastructure modernization, and why does my organization need it?
Network infrastructure modernization is the process of replacing or upgrading outdated network hardware, software, and architectures — such as aging switches, routers, and manual configuration systems — with current, automated, and cloud-compatible solutions. Legacy networks are a growing liability. They create security vulnerabilities, limit bandwidth, and can’t support the real-time workloads, remote access demands, and AI applications modern businesses depend on. Modernizing your network improves reliability, reduces operational risk, enables better visibility and control, and lays the technical foundation for future innovation. Organizations that defer modernization often discover the cost — in downtime, breaches, and lost agility — far exceeds the cost of the upgrade itself.
What is the difference between Infrastructure as a Service (IaaS) and Hybrid IT, and which is right for my business?
IaaS and Hybrid IT are complementary but distinct approaches. Infrastructure as a Service (IaaS) is a consumption model in which your organization outsources physical compute, storage, and networking resources to a managed provider — paying a monthly fee rather than making large capital hardware purchases. Hybrid IT is an architectural strategy that blends on-premises infrastructure, private cloud, and public cloud environments into a unified operating model. Many organizations use both: Hybrid IT defines where workloads live and how environments are integrated, while IaaS is one of the delivery mechanisms within that model. The right approach depends on your workload requirements, data sensitivity, compliance obligations, and budget model. As a vendor-agnostic infrastructure partner, OnX can assess your environment and recommend the optimal mix — often a phased approach that preserves existing investments while building toward a more flexible, cloud-aligned future.
How does network infrastructure support AI workloads, and what do organizations need to prepare?
AI workloads — including model training, inference, data pipelines, and real-time analytics — place dramatically higher demands on infrastructure than traditional transactional systems. They require significant compute power, high-throughput network connectivity, low-latency storage access, and robust data movement capabilities between on-premises environments and cloud platforms. Organizations that attempt to run AI initiatives on legacy infrastructure frequently encounter bandwidth bottlenecks, insufficient compute, and security gaps that stall proofs of concept before they can scale. Preparing for AI workloads typically requires a phased infrastructure assessment that identifies these gaps, followed by targeted modernization of network core, storage, and hybrid cloud connectivity. OnX's Forge AI framework is specifically designed to help organizations close the infrastructure gap before it becomes the reason AI stalls.
What security risks are associated with hybrid and multi-cloud infrastructure, and how can they be mitigated?
Hybrid and multi-cloud environments introduce several distinct security challenges: data can be exposed during transfer between private and public clouds, inconsistent security policies across environments create gaps attackers can exploit, and the expanded attack surface of distributed infrastructure increases overall risk. Additional risks include misconfigured cloud resources, inadequate access controls, and compliance blind spots when workloads span multiple platforms with different regulatory requirements. Effective mitigation requires a Zero Trust security architecture — where no user, device, or system is trusted by default — combined with consistent enforcement of identity and access management, continuous monitoring across all environments, encrypted data in transit and at rest, and a well-defined incident response plan. OnX integrates security into every infrastructure engagement, implementing next-gen firewall-as-a-service (FWaaS), advanced threat protection (ATP), and SOC services to maintain continuous defense across hybrid estates.
How do organizations evaluate whether to refresh infrastructure hardware or shift to a cloud or as-a-service model?
This is one of the most consequential decisions IT leaders make, and the right answer depends on several factors: the age and performance of current hardware, total cost of ownership (including maintenance, power, and staffing), workload characteristics, compliance requirements, and strategic direction. A hardware refresh may make sense when an organization has predictable, stable workloads, regulatory mandates requiring on-premises data residency, or significant remaining value in existing equipment. A shift to IaaS or a consumption-based model (such as HPE GreenLake) is often preferable when the organization wants to move IT spending from CapEx to OpEx, needs to scale rapidly, or wants to reduce the burden of hardware lifecycle management. Many enterprises land on a hybrid approach — refreshing core on-premises infrastructure while consuming cloud-based capacity for variable or growth workloads. OnX conducts thorough infrastructure assessments to help clients build a phased roadmap that maximizes ROI and aligns IT spending with strategic business objectives.
