In an era where traditional networks can no longer keep pace with digital innovation, Latin American telecom operators face the urgent challenge of transitioning to more flexible, scalable, and efficient infrastructures. Whitestack emerges as a key enabler of this evolution, delivering a comprehensive solution built on open technologies, deep regional expertise, and a forward-looking vision for Telco Cloud.
What is Telco Cloud?
Telco Cloud is a modern approach that enables operators to build and operate on-premise private clouds with full infrastructure control. From physical hardware to network function orchestration, this model virtualizes and automates Telco services on an open, interoperable architecture. Unlike legacy vendor-locked solutions, it significantly reduces total cost of ownership (TCO) while enabling smarter, sustainable investments and technology independence.
At its core, Telco Cloud combines performance, openness, and flexibility—capable of running both network functions (VNFs/CNFs) and traditional IT workloads on a single converged platform.
Whitestack's End-to-End Open Approach
One of the pillars that distinguishes Whitestack is its end-to-end approach, spanning from physical infrastructure to the highest layers of automation and operations. This comprehensive proposition enables operators to build a Telco Cloud with all necessary components, fully open and coherently orchestrated.
From hardware provisioning for servers and switches – including racks and connections – through the deployment of cloud infrastructure software (for virtual machines and containers), up to workload orchestration, automation tools, and PaaS solutions, Whitestack delivers a complete, modular, and robust platform. This approach allows operators not just to implement a technical cloud, but to operate a carrier-grade Telco Cloud aligned with the sector’s demanding availability, performance, and scalability requirements.
Principles Defining Whitestack's Proposition
Open Technologies
The use of standards and open-source software forms the core of Whitestack’s vision. Building on recognized industry projects, the company promotes vendor-agnostic solutions that enhance interoperability, reduce costs, and prevent lock-in. This openness also enables access to continuous innovation emerging from global technical communities.
Optimized On-Premise Deployment
By operating in local environments, Whitestack’s Telco Cloud implementation can leverage Enhanced Platform Awareness (EPA) techniques that significantly improve the performance of virtualized network functions. This includes technologies such as:
DPDK (Data Plane Development Kit): Enables network packet processing in user space with low latency and high performance.
SR-IOV (Single Root Input/Output Virtualization): Provides virtual machines with direct access to physical network devices, reducing hypervisor overhead.
CPU pinning: Allocates specific processor cores to certain virtual machines to ensure more predictable performance.
NUMA awareness: Optimizes process, memory, and device allocation to avoid unnecessary cross-node operations, thereby reducing latency.
These mechanisms achieve lower response times and greater throughput, which is crucial for demanding scenarios like 5G networks, mission-critical services, or time-sensitive applications.
Horizontal NFV Model
Whitestack’s Network Functions Virtualization model gives operators control over their infrastructure, allowing them to freely select and combine network function providers. This maximizes operational efficiency and avoids dependence on closed solutions, enabling more agile and cost-effective technological evolution.
Support for Telco and IT Workloads
In an increasingly convergent environment, it’s essential to have a platform that supports both network functions and traditional workloads. Whitestack has designed its Telco Cloud to operate in both domains, enabling seamless integration between Telco and IT environments within the same cloud.
