Originally hosted in a colocation environment, GL Education faced the risk of cyber threats and downtime—both detrimental to its customers. They also faced challenges with uneven traffic patterns throughout the year, coupled with rapid international expansion.
Considering the seasonal nature of a typical school academic calendar, GL Education experienced fluctuating demands that traditional bandwidth licensing could not accommodate. Also, due to international expansion, the uneven and unpredictable patterns of usage had become amplified, with peaks in traffic greatly increasing the demand on its infrastructure. Solving this challenge in colocation environments would require license and equipment commissioning, which would be at risk of underutilization in other periods.
Colocation environments also proved problematic in the face of cyberattacks against other organizations using the same data center. Even a temporary outage directly impacted GL Education’s customers, leaving them unable to administer online tests during the outage. This resulted in difficult to accommodate, last minute changes to their testing schedules.
Finally, GL Education faced the challenge of managing highly sensitive user data. Their web deployment needed strong protection against attacks and compromise, and they needed to ensure that they remained compliant with strict data security standards both in the UK and their growing international clientele.
Azure looked to be an ideal platform for GL Education as it offered scalability, flexibility, and could easily accommodate their ever-fluctuating platform usage requirements.
It would have an immediate impact on their bandwidth over-purchases, and would provide the international scalability they needed for global expansion. The Test Factory’s Azure-focused platform would be ideal for scale on-demand, maximizing uptime while globalizing the business. Azure’s geo-availability would also enable GL Education to deploy its testing and assessment platform in multiple locations in the future, improving user experience, lowering latency, and adhering to strict compliance policies. This includes policies that prohibit the transfer of data relating to individual students offshore, which is required by some of the international markets that GL Education is planning to enter in the near future.
To ensure optimal security and adhere to strict compliance policies, GL Education searched for a firewall solution in Azure Marketplace and decided on the Barracuda CloudGen WAF. Since GL Education’s customers’ biggest concern is security of their digital data, compliance with ISO27001 certification requirements is very important. The Barracuda CloudGen would simplify and automate many elements of GL Education’s strict compliance policies.

GL Education’s platform uses Azure to provide an elastically scalable and highly available system at all times. Additionally, the use of some functionality within Barracuda’s CloudGen WAF automatically synchronizes between the clusters, providing instant recovery from outages. Combined, these solutions allow GL Education to easily scale without the risk of overspending or bursting fees.
The Barracuda CloudGen WAF deployment within Azure provides GL Education with redundancy and seamless failover capabilities in response to outages, ensuring maximum uptime and higher customer satisfaction.
Sicherheit und Compliance
The Barracuda CloudGen WAF is compliant with major application-specific requirements including PCI-DSS, HIPAA, FISMA, and SOX. It also provides robust identity and access management, and data loss prevention capabilities to ensure privacy of sensitive data. In addition, Microsoft offers the most comprehensive set of certifications and attestations of any cloud services provider. With these features, GL Education’s customers can be confident that the security of their data will not be compromised.
Planning for the Future
In January 2016, GL Education released the alpha version of their new delivery platform, and has since moved into a larger scale customer beta program. GL Education is confident that they are ready to roll out the offering to a larger customer base after a successful round of penetration testing that resulted in zero security concerns. They plan to have their first live, multi-country deployment up and running by September, which will include a collaborative initiative with the National Institute of Education Sciences (NIES) in China to administer its Cognitive Abilities Test in Putonghua to 25,000 students.
To further their international expansion, GL Education is also working on localizing their platform for deployment into more non-English speaking regions. The flexibility and security of the Barracuda CloudGen WAF running on Azure is key to unlocking this additional global growth vector.
Results and Impact
GL Education has experienced impressive results from its Azure and Barracuda CLoudGen WAF deployments. When GL Education moves more customers to the new platform later in 2016, Glover believes that it will substantially reduce the operational cost of provisioning its digital assessments.

Without Azure, GL Education would have potentially had to commission a collocated data center in each region their solution is deployed in, which would be a costly and difficult task for them to plan and deliver.
Together, the Barracuda CloudGen WAF and Microsoft Azure cloud platform transformed GL Education’s security and efficiency, and is empowering their international expansion.
