关于客户
Quizlet is one of the largest educational websites in the world. Founded in 2005 by a 15-year-old student, the site now attracts over 12 million unique visitors every month, doubling its user base every year for six consecutive years. Quizlet does not have a pre-determined curriculum; instead, it designs powerful, easy-to-use software that empowers students of all ages to pursue self-defined learning goals. The site offers more than 15 million study sets for users and hosts more than 1.2 million study sessions every day. Supported by ads, Quizlet offers its vast library of content at no charge to students and teachers. In August 2012, the company released an iPhone app, which attracted more than 1 million downloads in a matter of months, making Quizlet the second most popular free education app in the U.S. iPhone store.
挑战
Quizlet, an educational website, was experiencing exponential growth in its user base, putting extraordinary pressure on the company to keep pace with the growing demand. The company was expecting to welcome 150 million visitors over the next 12 months, many of whom were students who expected fast website performance. In addition to faster page loads, data reliability was a major consideration for Quizlet, as users were uploading large amounts of data every hour. The company needed a reliable storage system that was available all the time, with no unplanned outages. Quizlet knew that it needed a first-rate cloud provider that could scale quickly and easily to meet user demand. In order to keep the site running optimally, the company also needed superior analytics for quick diagnosis of performance issues in near real time.
解决方案
Quizlet turned to a combination of first-rate vendors to optimize its cloud environment. The company chose Joyent as its cloud provider for its ability to provide up-to-the-minute data on performance issues across the network and application monitoring software that could pinpoint the source of any problem within Quizlet’s increasingly complex code base. With Joyent cloud services deployed on a robust ZFS layer, Quizlet had access to a powerful suite of network monitoring tools. To achieve comprehensive visibility across all aspects of its environment, the company also needed an application monitoring solution that would diagnose problems at the code level. This is where New Relic came in. The combination of DTrace and New Relic provided Quizlet with the ultimate toolset for quickly identifying, isolating, and correcting performance issues.

Case Study
IoT platform Enables Safety Solutions for U.S. School Districts
Designed to alert drivers when schoolchildren are present, especially in low-visibility conditions, school-zone flasher signals are typically updated manually at each school. The switching is based on the school calendar and manually changed when an unexpected early dismissal occurs, as in the case of a weather-event altering the normal schedule. The process to reprogram the flashers requires a significant effort by school district personnel to implement due to the large number of warning flashers installed across an entire school district.

Revolutionizing Medical Training in India: GSL Smart Lab and the LAP Mentor
The GSL SMART Lab, a collective effort of the GSL College of Medicine and the GSL College of Nursing and Health Science, was facing a challenge in providing superior training to healthcare professionals. As clinical medicine was becoming more focused on patient safety and quality of care, the need for medical simulation to bridge the educational gap between the classroom and the clinical environment was becoming increasingly apparent. Dr. Sandeep Ganni, the director of the GSL SMART Lab, envisioned a world-class surgical and medical training center where physicians and healthcare professionals could learn skills through simulation training. He was looking for different simulators for different specialties to provide both basic and advanced simulation training. For laparoscopic surgery, he was interested in a high fidelity simulator that could provide basic surgical and suturing skills training for international accreditation as well as specific hands-on training in complex laparoscopic procedures for practicing physicians in India.

Implementing Robotic Surgery Training Simulator for Enhanced Surgical Proficiency
Fundacio Puigvert, a leading European medical center specializing in Urology, Nephrology, and Andrology, faced a significant challenge in training its surgical residents. The institution recognized the need for a more standardized and comprehensive training curriculum, particularly in the area of robotic surgery. The challenge was underscored by two independent studies showing that less than 5% of residents in Italian and German residency programs could perform major or complex procedures by the end of their residency. The institution sought to establish a virtual reality simulation lab that would include endourological, laparoscopic, and robotic platforms. However, they needed a simulator that could replicate both the hardware and software of the robotic Da Vinci console used in the operating room, without being connected to the actual physical console. They also required a system that could provide both basic and advanced simulation training, and a metrics system to assess the proficiency of the trainees before they performed surgical procedures in the operating theater.

Edinburgh Napier University streamlines long-distance learning with Cisco WebEX
• Geographically dispersed campus made in-person meetings costly and inconvenient.• Distance-learning programs in Malaysia, India, and China required dependable, user-friendly online tools to maximize interaction in collaborative workspaces.• Virtual learning environment required a separate sign-in process, resulting in a significant administrative burden for IT staff and limited adoption of collaboration technology.

8x increased productivity with VKS
Before VKS, a teacher would spend a lot of time showing a group of 22 students how to build a set of stairs within a semester of 120 hours. Along with not leaving the teacher much time to provide one-on-one support for each student to properly learn carpentry, it also left a considerable amount of room for error. Key information would be misinterpreted or lost as the class was taught in the typical show-and-tell way.

Scalable IoT Empowering GreenFlex's Sustainable Growth
GreenFlex, a company that supports sustainable development, decarbonization, and energy efficiency, faced several challenges in its quest to expand its business. The company needed to deploy a robust and sustainable IoT technology to support its growth. It was crucial for them to monitor and control devices at customer sites in a safe and reliable manner. They also needed to integrate devices across a range of communication protocols and gather and act on data to meet efficiency targets. GreenFlex had previously built IoT capabilities into its digital platform, GreenFlexIQ, to monitor and manage customer sites remotely. However, they soon realized that they needed a new platform to support their ambitions. They needed a platform that could scale to connect more devices for production management and make it easier for the operations team to manage devices in the field.
