About The Customer
Lewisville Independent School District (LISD) covers 127 square miles in Texas and serves more than 52,000 students across 69 campuses. It serves all or portions of 13 municipalities in North Texas. The district is committed to using state-of-the-art technology in its educational approach, incorporating online instruction and providing iPads to staff and students. LISD is recognized as a leader in using technology to enhance education, with initiatives like flipped classrooms and online collaboration. The district's network team consists of only four IT technicians who manage over 100,000 network devices, including laptops, iPads, and other machines. The district's BYOD initiative allows students and employees to bring their own devices, further increasing the number of devices on the network.
The Challenge
Five years ago, Lewisville Independent School District (LISD) transitioned from a Novell system to Microsoft Windows servers for managing DNS and DHCP. However, within six months, it became apparent that the system couldn't deliver the stability needed to support the district's commitment to incorporating technology into teaching and learning. The district is a leader in using technology to revitalize education, with initiatives like online instruction and providing iPads to staff and students. The network team, consisting of only four IT technicians, manages over 100,000 network devices, including laptops, iPads, and other machines. The district's BYOD initiative further increases the number of devices on the network. The challenge was to have a DNS/DHCP system resilient enough to handle the traffic over the upgraded network.
The Solution
Five years ago, the Network Department at LISD asked Infoblox to demonstrate its solution. Impressed with the demonstration, they recommended it to IT management, who approved the purchase of 12 Infoblox appliances. These appliances were deployed at a single location in the district, with eight used for internal DNS and DHCP, one high-availability pair for external DNS, and another pair dedicated to consolidated database functions. The solution was installed over a weekend, with a smooth cutover from the legacy Microsoft system. Infoblox Professional Services provided automation scripts, helped implement the solution, and made periodic site visits to ensure everything was running smoothly.

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.

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.

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.
