Teky teaches coding, graphic design, and 3D technology to children across Vietnam — and every live class, every lesson, every student login depends on infrastructure that cannot lag. After experiencing connectivity issues with international cloud providers, Teky switched to GreenNode and never looked back.
Challenge
As Teky scaled its hybrid learning model across online and offline channels, its existing infrastructure created friction at every step:
- High on-premise setup costs: Building internal infrastructure required significant upfront investment and a dedicated technical team to maintain it.
- Unstable connectivity with global cloud providers: Servers hosted abroad — such as in Singapore — resulted in high latency and inconsistent access speeds, directly affecting the quality of real-time online classes.
- Difficulty scaling quickly: Enrollment spikes during peak admission seasons put sudden pressure on the system, with no easy way to scale on demand.
- Data backup and recovery requirements: As an educational organization, Teky needed reliable, always-on backup and rapid restoration capabilities to protect student learning data.
Solution
After evaluating multiple providers, Teky chose GreenNode for its combination of competitive pricing, flexible infrastructure, and strong local reputation:
- vServer deployed to power all learning systems — including online class platforms, student management, and course content delivery.
- Domestic infrastructure in Vietnam delivering significantly lower latency and more stable access speeds compared to overseas providers — critical for real-time online classes.
- Flexible, on-demand scalability with no service interruptions when new branches or enrollment surges require additional capacity.
- Comprehensive technical support covering backup and restore, system monitoring via vMonitor, and flexible pay-as-you-go billing.
GreenNode met exactly what Teky was looking for. We chose GreenNode for its reasonable cost, flexible solutions, and fast deployment. With a professional support team and the credibility of the GreenNode platform, I am confident this infrastructure will deliver outstanding results for Teky.
Result
- Significant cost optimization: Infrastructure costs were reduced considerably compared to using international providers, especially as operations scaled.
- Stable, nationwide access speeds: Students across Vietnam now experience consistently fast and reliable connectivity during online classes — with noticeably lower latency than before.
- Reduced operational risk: All data and systems run on a domestic cloud platform with robust monitoring and recovery capabilities, minimizing the risk of disruption.
- Faster scalability: The platform scales seamlessly to absorb enrollment spikes and new branch openings — keeping pace with Teky's rapid growth.
Future plans
Teky will continue expanding its learning ecosystem and integrating new technologies, prioritizing GreenNode's domestic cloud infrastructure for its speed, stability, and responsive technical support throughout its long-term growth journey.
