Case Study

A fast-growing Online Training Organization uses CoreStack platform as a catalyst to propel its growth

Customer Background

Our customer is a live and interactive e-learning platform that is revolutionizing professional online education. They help professionals learn trending technologies for career growth. They are the fastest growing and have the highest course completion rate in the industry.


As the customer traversed the path of high-speed growth, they soon realized that their Learners (i.e. their end customers) and Trainers were struggling with the cumbersome process of setting up Training labs.

Trainers used their own local version of training labs to demo during virtual classroom sessions. Whereas Learners had to invest a lot of time in setting up their own local labs in their PCs. Consequently, precious class room time was wasted in troubleshooting different environment related issues of Learners.

Also, as a common environment was not available, assessment and grading of Learner’s performance was a challenge. They had to depend on offline assignment submissions.

Due to limited availability of Big data administrators and Cloud experts, customer could not attempt any innovation like Cloud based labs. They were also apprehensive about the lack of clarity in calculating the cost per learner, if Cloud based labs are to be provided.

Business Goals

To overcome these challenges, the management decided to pursue two important goals

  1. Leverage technology to provide great user experience. To achieve this goal, it was critical to ensure that training labs are available anytime, anywhere without the need for any local set-up
  2. Build a predictable cost model in provisioning training labs


After evaluating a bunch of other options, customer finally selected CoreStack’s Cloud lab-as-a-service platform (CLaaS) to build their training labs. The entire solution was ready to be integrated with customer’s LMS in less than 2 weeks of time.

  1. The lab environment was set up with high availability of 99.95% for 3000+ learners and 100+ concurrent learners
  2. A dedicated custom cluster was set up and managed in Cloud unlike other comparative products
  3. The lab environment was fully integrated with customer’s LMS using APIs offered out-of-the-box by CoreStack
  4. The performance of the labs was optimised for customer’s usage and ensured auto-scaling at all layers
  5. All datasets and common files were pre-uploaded and accessible to all Learners
  6. All lab components are accessible from web browsers including Linux consoles, IDE, FTP and others
  7. Different access levels were provided to Learners, Trainers and Graders as per business needs.
  8. Each Learner’s data on assignments and activities securely isolated from other Learners. Only Trainers could access them for assessment/grading

A simple per-learner pricing model was provided which was fixed and predictable, irrespective of scale and usage. This significantly helped them in estimating the overall budgetary requirement and get all required approvals in a single go.


  • Learner enrolments up by 400% in less than a year for the Big Data course
  • Course completion rates increased by 45%
  • Trainer’s productivity increased by 15% as no more time wasted on troubleshooting

Future Plans

  • Piloting automated reports on hands-on lab activity to review Learner engagement
  • Further streamlining of the Learner assessment and grading process
