Cloud-Native Revolution: Harmonic VOS and Red Hat OpenShift Mastering Video Delivery, Cost, and Scale

The telecommunications industry stands at a critical inflection point. High-definition streaming has exploded beyond all projections, shattering the capacity limits of traditional video infrastructure. Service providers now find themselves navigating a perfect storm: a relentless data deluge, escalating security and compliance requirements, and operational costs that threaten to spiral out of control.

Customer expectations have reached unprecedented heights—viewers demand flawless, buffer-free experiences across every device and network condition. Yet legacy systems, built for an era of linear broadcasting, simply weren't designed for today's dynamic, on-demand streaming reality. Incremental patches and workarounds are no longer sufficient.

The path forward is clear: cloud-native architecture represents not just an upgrade, but a fundamental reimagining of how video services are delivered at scale. For forward-thinking telco leaders ready to break free from the constraints of legacy infrastructure, the combination of Harmonic VOS Media Software deployed on Red Hat OpenShift offers a definitive, future-ready foundation—one that finally brings complexity under control while unlocking unprecedented flexibility, security, and operational efficiency.

Video-Specific Challenges

Service providers today navigate a perfect storm of video-related challenges that threaten both their infrastructure and their bottom line.

The data deluge.

Video traffic has exploded beyond all projections. Over the top (OTT) streaming platforms have fundamentally altered consumption patterns, with subscribers expecting instantaneous access to high definition (HD) and 4K content across multiple devices simultaneously. This exponential growth in video data traffic places enormous strain on existing network infrastructure, forcing service providers to constantly reassess capacity and investment strategies. The traditional approach of over-provisioning infrastructure is no longer economically viable, yet undersizing leads directly to service degradation, subscriber dissatisfaction, and ultimately churn.

Live event traffic spikes.

The data deluge challenge is more acute during live events. Major sporting events, award shows, and breaking news can drive millions of concurrent viewers to streaming platforms within minutes. These traffic spikes create extraordinary peak demand challenges that can overwhelm traditional unicast delivery mechanisms. Service providers who fail to anticipate and accommodate these surges risk catastrophic service failures at precisely the moments when brand reputation is most vulnerable.

The balancing act.

Service providers must simultaneously juggle multiple competing demands:

• They must deliver premium quality experience while working within finite bandwidth constraints.
• They must deal with escalating piracy threats that demand sophisticated content protection mechanisms.
• They must control operational costs in an environment of relentless margin pressure.

Security and compliance pressures.

The regulatory environment has never been more demanding. Stringent requirements around data sovereignty mean service providers must carefully control where content and subscriber data reside. Privacy regulations like the general data protection regulation (GDPR) impose severe penalties for non-compliance. Cybersecurity threats grow more sophisticated daily, requiring constant vigilance and investment. And emerging regulations around responsible AI governance add another layer of complexity to technology decisions.

Looking ahead to 2026, zero-trust network mandates are becoming standard practice across the industry. The traditional perimeter-based security model is giving way to a new paradigm where every access request must be verified, regardless of origin.

Sustainability commitments.

Environmental responsibility has moved from optional to essential. Over 300 major service providers have committed to achieving net-zero emissions between 2040 and 2050. This isn't merely about corporate social responsibility—it's about long-term business viability as regulators, investors, and customers increasingly demand environmental accountability. Video infrastructure, with its massive computational and cooling requirements, sits squarely in the crosshairs of sustainability initiatives.

Red Hat OpenShift: A Scalable Foundation for a Cloud-Native Video Infrastructure

As service providers confront these multifaceted challenges, many are reassessing their infrastructure foundations. The recent industry turbulence around VMware has accelerated a migration that was already underway: the shift to Kubernetes-based container orchestration platforms. Red Hat OpenShift has emerged as the enterprise platform of choice, and for the following compelling reasons.

A Secure, enterprise-grade alternative.

As service providers migrate away from traditional virtualization platforms, they need more than just a replacement—they need an extensible and common cloud-native platform. Red Hat OpenShift provides that evolution, offering a security-optimized, enterprise-grade Kubernetes distribution specifically designed for production workloads. It's not simply about running containers; it's about running them with the security, stability, and support that mission-critical video services demand.

Red Hat OpenShift enforces standardized security out of the box through mechanisms like restricted Security Context Constraints (SCC) and comprehensive compliance-ready frameworks. Unlike vanilla Kubernetes, which requires extensive hardening and customization to meet service provider security requirements, Red Hat OpenShift comes pre-configured with defense-in-depth security controls that align with industry best practices.

Operational excellence through centralization.

Managing distributed infrastructure across multiple data centers and edge locations represents an enormous operational challenge. Red Hat OpenShift addresses this through simplified, centralized management capabilities that provide a single pane of glass across hybrid environments. With over 500 plugins and add-ons available through the OperatorHub, Red Hat OpenShift offers extensibility without fragmentation.

This ecosystem approach means service providers can leverage pre-validated, supported integrations rather than building custom solutions. When new capabilities are needed—whether for observability, security, or storage—certified Red Hat OpenShift Operators are typically already available, dramatically reducing integration effort and risk.

Standing on trusted foundations.

Red Hat brings more than technology—it brings credibility. Backed by open source innovation and supported by a vast ecosystem of hardware vendors and technology partners, Red Hat OpenShift offers stability that service providers require when making platform decisions with decade-plus implications. The Red Hat partner ecosystem includes a majority of leading hardware vendors and independent software vendors (ISVs) in the telecommunications space that deliver broad compatibility and shared roadmaps.

“To help service providers address the exponential growth in video and master the industry’s complexity, Red Hat is pleased to collaborate with experts like Harmonic,” said Mark Longwell, director, Telco and Edge Alliances, Red Hat. “Red Hat OpenShift is the common cloud-native foundation for this transformation. It gives service providers the speed, security, and stability they need to accelerate innovation and meet their critical goals—from zero-trust compliance to sustainability commitments.”

Built for scale.

Perhaps most importantly, Red Hat OpenShift is explicitly designed for modern service provider workloads and growth trajectories. It incorporates specific capabilities like Single Root I/O Virtualization (SR-IOV), Data Plane Development Kit (DPDK), and real-time kernel support. These aren't afterthoughts or community extensions—they're core capabilities tested and supported by Red Hat, so that video processing workloads can receive the performance and determinism they require.

Harmonic VOS Media Software: Cloud-Native Video Excellence

While Red Hat OpenShift provides the cloud-native platform foundation, Harmonic VOS Media Software represents the evolution of video processing for the cloud-native era. Together, they form a powerful combination that addresses the full spectrum of service provider video challenges.

A comprehensive video platform.

VOS Media Software is more than a point solution—it's a comprehensive, software-based platform for managing complete video workflows from playout and encoding to packaging and origin. This end-to-end approach addresses both broadcast and OTT applications within a single unified platform, eliminating the complexity and inefficiency of managing disparate systems.

The platform provides service providers with unprecedented flexibility to ingest file or live content, including uncompressed video over IP. From there, VOS handles scheduling, channel playout, and content processing for both OTT streaming and broadcast delivery. Whether launching new streaming services, managing traditional broadcast channels, or delivering hybrid services that span broadcasting with full statmux capability to OTT streaming, VOS provides the complete feature set required.

Service providers can launch broadcast and OTT "everywhere TV" services rapidly, customizing and branding channels for millions of subscribers. The platform's integrated capabilities for live streaming, time shifting, network DVR, targeted ad insertion, and on-the-fly packaging and origin mean service providers can deploy sophisticated services without integrating multiple vendor solutions—a critical advantage when speed to market determines competitive success.

Cloud-native by design, not retrofit.

VOS isn't a legacy system running in containers—it's architected from the ground up as a true cloud-native video operating system. Built around Docker containers and microservices, VOS leverages Kubernetes orchestration to deliver the resilience and scalability that modern video services demand. The platform offers a rich application programming interface (API) set and a range of easy-to-use features accessible through an intuitive user interface.

At the heart of VOS is an orchestrator that connects and synchronizes all microservices for every workflow. This orchestrator abstracts and manages IT infrastructures using intelligent load-balancing mechanisms to optimize resource utilization and manage redundancy with minimum overhead. Through the Harmonic Hub administrative control center, service providers gain centralized visibility and control across their entire video infrastructure. This centralized management makes it remarkably simple to move an entire video platform from a private data center to a public cloud and vice versa—a capability that fundamentally changes infrastructure planning and disaster recovery strategies.

Each component is independently scalable, updatable, and resilient, eliminating the monolithic fragility of traditional video platforms. Service providers can finally say goodbye to the headache of siloed systems, with VOS providing unified management across diverse workflows and deployment models.

Critically, VOS has been validated as a cloud-native network function (CNF) on Red Hat OpenShift. This validation helps ensure carrier-grade lifecycle management, resilience patterns, and operational maturity. It means VOS isn't just compatible with Red Hat OpenShift—it's optimized for it, taking full advantage of the platform's orchestration, scaling, and self-healing capabilities.

This cloud-native architecture enables truly consistent deployment across private, hybrid, and multi-cloud environments. Whether running in an service provider’s data center, at the edge, or in public cloud, VOS maintains operational consistency, dramatically simplifying management and reducing the specialized expertise required for each environment.

Security embedded, not bolted on.

Security isn't an afterthought in VOS—it's foundational. The platform is fully compliant with Red Hat OpenShift's restricted security policies and role-based access control (RBAC) models. This means VOS adheres to the principle of least privilege, running with minimal permissions while maintaining full functionality.

VOS aligns seamlessly with zero-trust network principles, treating every request as potentially hostile and requiring verification at every layer. This approach directly addresses the 2026 regulatory mandates while protecting against sophisticated threats. Additionally, VOS helps service providers meet increasingly stringent data sovereignty and privacy regulations by providing flexible deployment options and granular control over data location and access.

Deployment automation at scale.

Perhaps nowhere does the cloud-native advantage shine more brightly than in deployment and lifecycle management. VOS comes pre-integrated with modern continuous integration/continuous delivery (CI/CD) workflows, leveraging Git for configuration management, ArgoCD for GitOps-style deployments, and a dedicated VOS Operator that encodes operational best practices.

Declarative deployments through custom resources mean that infrastructure is defined as code, ensuring repeatability and configuration consistency across environments. A service provider deploying VOS in São Paulo can leverage the exact same automation that was validated in Stockholm, dramatically reducing deployment risk and time.

The impact is transformative. What once required weeks of manual configuration and validation now happens in hours, with dramatically higher confidence. Updates and scaling operations follow the same declarative pattern, making routine what was once risky and complex.

Future-proof architecture for evolving needs.

Technology decisions made today must serve tomorrow's requirements. The combination of Red Hat OpenShift's common cloud-native platform approach with Harmonic's VOS Media Software provides service providers with a future-ready infrastructure for evolving video operations.

As new video codecs emerge, they can be integrated as new microservices without platform disruption. As artificial intelligence and machine learning (AI/ML) capabilities become central to video processing—for quality optimization, content analysis, or predictive scaling—they slot naturally into the existing architecture. As edge computing requirements evolve, the same VOS components that run in the core can be replicated to edge locations with consistent operation and management.

This architectural flexibility means service providers aren't locked into today's assumptions about video delivery. They can evolve, experiment, and adapt without the platform itself becoming a constraint.
