Udacity needed to manage enormous fluctuations in VM demand, sometimes seeing spikes of 2,000-3,000 VMs accessed in minutes. The company required extremely efficient IT spending to keep student costs low while maintaining highly-reliable services for their online learning platform.
Udacity partnered with DoiT International for proactive cloud spend management on Google Cloud. DoiT provides real-time alerts for cost spikes, identifies optimization opportunities, and delivers solutions typically within 30 minutes. The partnership includes custom auto-scaling solutions and continuous monitoring of compute resources.
DoiT has been central to our success with Google Cloud. They frequently reach out to us when spikes in spending occur, and they are incredibly responsive to our needs, typically finding solutions to our problems in 30 minutes or less.
Will Kessler, Director of Engineering, Udacity
Udacity serves between 50,000 and 60,000 students whose support requires the use of 100,000 to 200,000 VMs every day. The company sometimes sees spikes of anywhere from 2,000 to 3,000 VMs accessed in minutes. Google Compute Engine powers the VMs, and Google Kubernetes Engine is built into the hypervisor infrastructure to assist with managing and maintaining systems, helping the company handle surges with minimal or no disruption.
DoiT proactively informs Udacity when there are opportunities to reduce costs while maintaining the same functionality across compute resources. For example, DoiT once noticed the tripling of SSD costs over just a few days, alerted Udacity, and discovered the issue was related to SSDs becoming detached and not properly deleted. DoiT also recommended balanced persistent disks, which saved Udacity 75 percent on drives since making the change.
Throughout the pandemic, Udacity has seen large demand for nanodegrees as people want to learn skills that enable them to continue earning income while working remotely. Enterprise customers are increasing their investment in employee learning. One of Udacity's largest enterprise customers had employees complete an analytics nanodegree, and one student used that knowledge to identify efficiencies that could yield as much as $10 million in savings annually.
All of the work completed with Google Cloud and DoiT positioned Udacity to seamlessly manage activity surges and spikes in demand. Regardless of how quickly the company needs to scale up or down its VMs and SSDs, Google Cloud provides the requisite power and flexibility while DoiT maintains a close eye on spend, use, and opportunities for further optimization. This allows engineers and staff to focus on core business of educating professionals rather than IT maintenance.
Empowered with the right technologies and an efficient model for cloud spending, Udacity is expanding its nanodegree programs into even more areas. The organization is working on approaches to enable on-the-fly skills assessments and mapping while greatly personalizing learning experiences. Google Cloud and DoiT provide the agility needed to support increasing future demands and tap into analytics and microservices tools.

“PerfectScale gives us the confidence to automate Kubernetes optimization while letting our engineers focus on building what matters.”
Josh Zarrabi, Infrastructure Engineer
“Without PerfectScale by DoiT, I don't know how we would do it. We'd have to have twice the number of people on my team to stay on top of it. With PerfectScale, we can focus on the more strategic issues.”
David Adkins, Director of Software and Platform Engineering
Connecting IBM and AWS privately was the piece we needed to get right, and we wanted to move faster on it than we could on our own. DoiT worked through the options with us, found the subnet overlap that was breaking the routing, and made it stable. That unblocked everything else.

Attribute™'s platform is truly unique. We now have crystal-clear visibility into our cloud spend at the workload and tenant level, and that insight has already led to actionable savings and powerful insights as we further scale our service.
Paul White, VP of Engineering, Shasta Cloud
We have worked with DoiT for many years, and there has been an increasing number of capabilities and features in DoiT Cloud Intelligence. We've embedded features such as Cloud Analytics and Reports in our own FinOps processes, it's become core to what we do.
Martin Lee, Director of Operations
DoiT gave us the confidence to move from experimentation to production. They helped us understand the right way to build AI for the real world.
Milad Rezazadeh, CTO
Attribute™'s cost grouping technology took our cost visibility and allocation to a whole new level. Now, our teams are fully accountable for their budgets, significantly improving our cloud efficiency and helping us minimize unnecessary costs.
Eli Zilbershtein, Head of DevOps, Hippo
You can't tag a customer in a multi-tenant environment. Attribute™ finally shows us what each customer costs and what's driving those costs.
Omri Cohen, Director of Engineering, Platform
Attribute™'s data is truly unmatched. No other solution on the market could deliver the precise customer cost and usage profiles we needed in such a complex infrastructure. Within weeks, the data from Attribute™ transformed our understanding of cost structures, influencing key strategic decisions in pricing, renegotiations, and market positioning.
Jonathan Langer, COO, Claroty
Attribute™ simplified tracking customer costs in our multi-tenant environments. Customer cost measurement is now clear and standardized, and finance gets the business context they need. Integration was quick and required no changes.
Kfir Lippmann, CFO, Salt Security
Attribute™ translates complex cloud bills into actionable, business-centric insights that empower our engineering teams to take true ownership of their costs.
Balamurugan Mohandossgandhi, Head of IT and Infrastructure, PropertyGuru
This has let us get a better idea of what our cost of goods sold really is. It's not every day you come across something that delivers value as quickly as yours did for us. I was seeing useful insights inside the POC, and we had only deployed it to a couple of real clusters.
Jason Moore, Principal DevOps Engineer, Accrete AI
Eliminating the need to tag thousands of resources has freed up my team and we've invested our efforts in enhancing our platform significantly.
Ziv Sivan, VP of Engineering
Let us show you what ships this week.
