About The Customer
Cvent is a market-leading meetings, events, and hospitality SaaS provider, with nearly 4,000 employees and more than 200,000 users worldwide. The company has been delivering innovative solutions for over 20 years, enabling marketers and event professionals around the world to create engaging, impactful experiences. In 2020, the global COVID-19 pandemic forced events into virtual environments, which transformed the industry and accelerated its digital transformation. In response to this, Cvent pivoted their entire product roadmap strategy to focus on building a new solution for virtual, hybrid, and in-person events. The result was the Cvent Attendee Hub, which was launched at Cvent CONNECT, Cvent's annual customer conference.
The Challenge
Cvent, a market-leading meetings, events, and hospitality SaaS provider, had to pivot their entire product roadmap strategy to focus on building a new solution for virtual, hybrid, and in-person events due to the global COVID-19 pandemic. They planned to launch their new platform, the Cvent Attendee Hub, at Cvent CONNECT, their annual customer conference, and host the event on it. This meant that its performance had to be impeccable, and they only had six months to deliver. Ian Schell, Site Reliability Architect at Cvent, was tasked with ensuring that the Attendee Hub could accommodate the broad reach and increased registration volume of virtual events, which can often exceed that of in-person events. There were many unknowns surrounding usage patterns and scale, because the product was completely new, and the number of participants could be an order of magnitude higher compared to some in-person events.
The Solution
Cvent used Datadog APM and Continuous Profiler to build and successfully launch the Cvent Attendee Hub under tight deadlines. The unified Datadog platform enabled Cvent to implement a culture of observability across the organization, and ship code more frequently and reliably. As they were building the Attendee Hub, Cvent used Datadog APM every step of the way to validate design decisions and identify areas in need of optimizations. At one point during the load testing process, APM helped Cvent engineers detect and fix a bug in their code that would likely have not been caught as quickly —if at all—with previous tools. In another case, the team leveraged the Datadog flamegraph, which correlates service spans with relevant telemetry on the same screen, to detect an ECS instance that was experiencing elevated latency. The team was able to quickly determine that the host was overloaded and that the ECS CPU reservation was too low—without having to switch contexts. This information enabled them to make an informed decision to size up the instance appropriately.

Darwin Ecosystem: Accelerating discovery and insight through cutting-edge big data and cognitive technologies
Darwin Ecosystem was founded with a unique vision of harnessing chaos theory mathematics to uncover previously hidden connections in unstructured data. The company’s algorithms can look at all the data generated by any source (such as news, RSS feeds and Twitter), and analyze how a specific set of concepts within that data are evolving over time. This is particularly valuable in situations such as business and competitive intelligence, social research, brand monitoring, legal discovery, risk mitigation and even law enforcement. A common problem in these areas is that a regular web search will only turn up the all-time most popular answers to a given question – but what the expert researcher is actually interested in is the moment-tomoment evolution of the data available on that topic. Darwin’s algorithm is computationally intensive, and the sources of data it correlates can be vast. To bring its benefits to a larger commercial audience, Darwin needed to find a way to make it scale.

Delivering modern data protection with cloud scale backup from Cobalt Iron and IBM
Organizations are struggling to modernize their legacy data protection environments in the face of growing demands around new infrastructure, new applications, and budget consolidation. Virtualization and modern application development processes have significantly outgrown legacy backup architectures. In response, infrastructure teams have created multiple backup solution types to handle the varying SLAs (performance, scale, cost) required by their business sponsors. However, the sheer number and variety of solutions in this uncontrolled expansion creates huge amounts of work, threatening to overwhelm the IT team in many organizations. Today, developers may add new applications and virtual server instances by the hundreds per day without accounting for the restrictions of the existing backup infrastructure. They leverage the cloud for immediate compute and storage resources, yet rarely communicate succinctly with corporate IT to ensure that the appropriate data protection services are in place.
