As video consumption surged across emerging and mature markets alike, the client found itself at a defining inflection point. With a rapidly growing user base reaching 62.4 million active users, growing at an 11% year-over-year rate, the platform needed to evolve from supporting growth to powering it at scale. This expansion, driven heavily by key markets in South-East Asia, the Middle East and North Africa, directly triggered the need for a digital core capable of converting traffic spikes into sustained revenue and subscriber retention.
Persistent stepped in as a strategic engineering partner to help the client rethink its digital core by transforming its architecture, accelerating innovation and unlocking the next phase of global expansion.
Growth Outpacing the Platform: The Baseline Challenges
The client’s success brought with it a new set of challenges. Its backend and content platforms, built for an earlier phase, struggled to keep up with the demands of rapid scale, multi-region expansion and rising user expectations.
Before the transformation, operations were constrained by significant technical baselines and engineering bottlenecks:
- Infrastructure Costs & Inefficiencies: The platform suffered from legacy over-provisioning, resulting in an estimated $300k in annual infrastructure waste due to underutilized virtual machines.
- Slow-Release Cycles: Feature rollouts were heavily delayed, with release cycle durations taking up to 8 weeks per major update.
- Testing & Pipeline Bottlenecks: Engineering velocity was severely impacted by a heavily manual delivery process, where 70-80% of testing was performed manually. This resulted in prolonged regression cycles lasting 4-5 days, compounded by fragmented management across 3 separate deployment environments.
The business needed more than incremental fixes; it required a fundamental transformation to eliminate these operational constraints, reduce high baseline costs and support seamless user experiences across geographies.
Re-architecting for Speed, Scale and Efficiency
Persistent approached the transformation holistically, re-engineering not just systems, but the way innovation was delivered.
1. Maximizing Performance with Java-to-Golang Modernization
At the heart of the transformation was a shift to a cloud-native, microservices-driven architecture. Legacy Java services were modernized into Golang-based microservices. This language migration delivered precise technical advantages:
- 80% improvement in CPU and memory utilization.
- 80% reduction in application latency, drastically improving response times.
- Direct infrastructure cost savings tied exclusively to Golang’s lightweight resource footprint.
2. Executing Multi-Region Cloud Migration
To support future scalability, workloads were strategically migrated from GCP to AWS. This targeted migration aligned the infrastructure with long-term global growth objectives, achieving:
- 90% reduction in cross-region data transfer latency.
- Elimination of localized downtime, guaranteeing 99.95% platform availability during high-traffic streaming events.
3. Modernizing DevOps and Product Engineering
Persistent took ownership of end-to-end product engineering, driving feature development from concept to production with rigorous testing, code quality standards and architecture oversight.
Behind the scenes, DevOps transformation became a force multiplier. CI/CD pipelines were modernized, automation was expanded to shift the testing landscape to 90% automated and only 10% manual, while regression cycles were slashed to just 4-6 hours. This eliminated pipeline inefficiencies across environments, drastically boosting release confidence.
4. Optimizing Content Management Services (CMS)
In parallel, content management services were containerized and optimized to enhance content delivery performance. Legacy VMs were completely eliminated, yielding:
- An approx 80% reduction in CMS build and deployment times (slashing it from 60 minutes down to just 10 minutes).
- Direct infrastructure savings from VM decommissioning.
- 50% faster metadata rendering on user screens globally.
From Constraint to Competitive Advantage
The transformation translated directly into business impact across cost, performance and speed.
1. Breaking Down OPEX Reductions
Operational efficiency improved significantly, resulting in a ~30% overall reduction in platform OPEX. This macro-financial turnaround was driven by highly targeted operational improvements across separate cost centers:
- A 30% reduction in baseline cloud infrastructure spend realized via migration and right-sizing workloads on AWS.
- Micro-efficiency savings from Golang resource optimization and complete legacy VM elimination.
- A 50% reduction in manual labor overhead achieved by automating the QA pipeline and streamlining CI/CD workflows.
2. Enhancing Platform Scale and Agility
The new architecture enabled the client to seamlessly scale across regions, supporting over 10 million concurrent users while maintaining consistent, buffer-free performance. Engineering agility saw a major step-change; transforming the regression cycle from days to hours accelerated the broader deployment and feature-release timeline by 40%, allowing faster rollouts and quicker response to market needs.
3. Powering Measurable Business Growth
At a platform level, this engineering transformation directly underpinned the client’s commercial expansion. Enhanced platform stability and a faster feature delivery cycle contributed to a 17% increase in subscribers over the engagement period. This ultimately empowered the client to scale to 62.4M monthly active users and 16.8M paid subscribers, reinforcing its leadership in digital video delivery.
A Platform Built for What’s Next
What began as a modernization initiative evolved into a strategic transformation, turning the client’s platform into a scalable, resilient and innovation-ready digital engine. With a future-proof architecture and a faster path from idea to production, our client is now positioned to not only meet demand but shape it.
By partnering with Persistent, our client successfully transitioned from a constrained legacy environment to a modern, scalable and high-performance digital platform. The transformation not only addressed immediate challenges around cost and scalability but also laid the foundation for continuous innovat
