This article examines the transformation, technical stack, benefits, and outstanding questions. It also explores lessons for other operators weighing a Cloud-Native Network roadmap. However, real proof will emerge only when live Mobile Network traffic meets strict service targets. Meanwhile, analysts warn about sovereignty, lock-in, and cost volatility. Therefore, we will trace the multi-vendor timeline, outline the architecture, and weigh the pros and cons. Subsequently, you will gain an informed view of what a Cloud-Native Network means for commercial agility. Finally, we highlight certification paths that help teams master AI security across virtualised telecom cores.

Why Tune Talk Transformed

Tune Talk started as a price-focused MVNO serving roughly one million prepaid users. Competition from larger incumbents squeezed margins. Moreover, 5G spectrum costs threatened future profitability. Therefore, management pursued a Cloud-Native Network to slash operating expense and accelerate product launch cycles. The strategy aligned with national digital policies that promote cloud adoption across Malaysia.

Initial due diligence revealed that public cloud could deliver elastic capacity without new physical sites. Consequently, Tune Talk engaged XIUS in May 2024 to migrate core workloads onto AWS. Subsequently, Nokia and Mavenir joined to containerise the core and modernise OSS/BSS. Executives argued that an AI-driven service fabric would differentiate offers in the crowded Mobile Network market.

In short, survival required software-centric agility. Next, we track how the plan unfolded.

Key Multi-Vendor Journey

The roadmap spans three public milestones. Firstly, the XIUS deal moved charging, policy, and subscriber data to AWS in May 2024. Secondly, Nokia signed during MWC 2025 to deploy a containerized packet core valued at up to RM100 million. Thirdly, February 2026 saw Mavenir announce live Cloud-Native Network OSS/BSS and automation in production. Moreover, each phase introduced deeper AI-driven orchestration and self-healing capabilities.

Nokia’s core migration targets completion by end-2025. Meanwhile, Tune Talk reports that 80% of user traffic already passes through containerised elements. However, independent verification of latency and availability remains pending. Analysts therefore await telemetry from real Mobile Network workloads on AWS.

The timeline reveals rapid execution across several vendors. Now, let us inspect the technical foundation.

Core Architectural Building Blocks

Tune Talk’s Cloud-Native Network relies on microservices running in Kubernetes clusters across two AWS regions. Nokia provides containerized control and user plane functions. Mavenir supplies digital OSS/BSS, policy, and customer engagement APIs. Additionally, XIUS manages managed services for billing and mediation.

All components expose open APIs for CI/CD pipelines and automated testing. Therefore, new digital partners can integrate in weeks, not months. AI-driven analytics run on streaming data to predict faults and trigger self-healing workflows. Consequently, operations staff monitor exceptions rather than routine alarms.

Security teams follow zero-trust principles with encrypted service meshes and continuous compliance scanning. Professionals can enhance their expertise with the AI Network Security™ certification. Such skills help validate AI safeguards inside any Cloud-Native Network.

These building blocks underpin agility and resilience. Next, we examine financial and service gains.

Benefits And Early Payoffs

Tune Talk projects 60-70% operational efficiency once full automation stabilises. Moreover, new prepaid bundles now reach market in days instead of quarters. Customer self-service adoption has increased, cutting call centre loads. Mavenir highlights faster upsell conversions driven by AI-driven segmentation and dynamic pricing.

• 30% faster product rollout versus 2023 benchmarks.
• 25% lower cloud infrastructure cost per subscriber, according to internal dashboards.
• Eight new partner bundles launched across Malaysia since mid-2025.

Consequently, early metrics suggest the Cloud-Native Network already boosts revenue velocity. However, benefits remain contingent on meeting carrier-grade KPIs at scale.

Efficiency gains look promising yet still provisional. Therefore, scrutiny shifts to potential downsides.

Risks And Analyst Warnings

Analysys Mason points to data sovereignty rules that limit foreign cloud use for critical workloads. In contrast, Venture Insights notes hyperscaler lock-in risks when operators deploy a single Cloud-Native Network on public cloud. Furthermore, Light Reading highlights latency variability on shared infrastructure. Consequently, some regulators in Malaysia may demand hybrid or sovereign models.

Cost unpredictability also worries finance teams because cloud egress fees can spike during traffic surges. Nevertheless, Tune Talk argues that multi-vendor design gives negotiating leverage. Meanwhile, staff reskilling remains a challenge as software pipelines replace legacy methods. Professionals holding the earlier certification can fill that skills gap.

Analysts thus paint a mixed picture of cloud telco futures. Subsequently, we assess broader market implications.

Regional Market Impact Outlook

Malaysia’s MVNO market is forecast to reach USD1.06 billion by 2030 with 5.7% CAGR. Moreover, Mordor Intelligence cites cloud native OSS/BSS as a catalyst for that growth. Tune Talk’s Cloud-Native Network positions it to capture new digital segments ahead of rivals. Consequently, incumbents may accelerate similar projects to protect prepaid share.

The vendor expects more Southeast Asian signings, citing deployments with over 300 operators worldwide. In contrast, smaller players may wait for clearer regulatory guidance. Therefore, Tune Talk serves as a live reference model for policymakers.

Competitive dynamics will likely intensify as cloud maturity spreads. Finally, we outline lessons for the wider operator community.

Next Steps For Operators

First, validate claimed KPIs through independent latency, availability, and cost audits. Secondly, negotiate exit clauses and multi-cloud portability before committing core workloads. Moreover, invest in workforce training around Kubernetes, observability, and automated incident response. Professionals should pursue domain certifications to formalise skills. Therefore, consider the earlier AI Network Security™ program to future-proof career prospects.

Finally, build governance frameworks that balance innovation with sovereignty and customer trust. Nevertheless, remember that technology alone cannot fix weak business models.

Disciplined execution turns buzzwords into sustainable advantage. Operators who plan holistically will extract the most value.

Tune Talk’s journey offers a timely glimpse into the possibilities of software-defined telco operations. The operator stitched together a modular cloud-native platform using AWS, Nokia, and a vendor ecosystem. Early metrics show faster rollouts and lower cost, yet definitive proof will depend on live traffic telemetry. Consequently, other Malaysia rivals watch closely before scaling similar models.

Nevertheless, the case already pressures incumbents across ASEAN to modernise architectures and skills. Industry professionals should follow the lessons, evaluate suitable certifications, and act decisively while regulations evolve. Act now and turn cloud disruption into competitive edge. Therefore, start small with non-critical workloads, measure outcomes, and iterate toward full autonomy.
