Digital education and information technology

The year the pandemic hit, CityU moved its entire teaching operation online in just 8 days — not because of last-minute improvisation, but because of a system migration completed five years earlier. This article maps out CityU's digital education infrastructure: the learning management system (LMS), identity and login, portals and everyday applications, network and computing resources, email and cloud office tools, plus the teaching policies drawn up for the generative-AI wave and the university's online pivot during the pandemic.

IT service details (ports, capacities, versions) are updated year by year; this article is based on verifiable, publicly documented institutional facts.

# 1. The learning management system: from Blackboard to Canvas

CityU's central learning management system (LMS) has gone through a migration from Blackboard to Canvas. The university switched to Canvas, provided by Instructure, in 2015^※, replacing the old Blackboard, on the grounds of Canvas's stability and its scalability as demand for online learning grew.

The switch was not done overnight; it was a phased transition spanning an entire academic year. According to the migration arrangements of CityU's e-Learning team at the time, the move to Canvas ran from Semester B of the 2014/15 academic year all the way through the 2015 Summer Term^※. For courses with extensive materials or online quizzes that wanted to keep their old content, the team offered a course-by-course migration service upon application from instructors. This window of "two platforms running side by side, gradually moving house" allowed the University to sort out course assets, assessment question banks and enrolment lists before the official switch — groundwork that quietly prepared it for rapid scaling in the pandemic years.

The current LMS is provided by Instructure, runs on a SaaS (software-as-a-service) model, and is hosted on Amazon Web Services (AWS) in Singapore^※. CityU's official digital-learning support pages likewise point to Canvas as the entry point for the student LMS^※. On day-to-day operation, a few verifiable mechanisms are worth recording: the platform domain is canvas.cityu.edu.hk; students log in with their EID and password; and updates roll out on a two-week cycle^※, meaning users are always on the latest version of Canvas rather than a frozen snapshot that gets upgraded every few years. Course sites are generated automatically each semester from the Master Class Schedule and populated with student enrolment lists; changes to enrolment are reflected synchronously in the corresponding course sites and groups, which are used for communication and grading.

In short: CityU's current central LMS is Canvas; Moodle is not CityU's institutional LMS — this site could find no trace on official pages of Moodle being adopted as the university-level platform, and the claim that "CityU uses Moodle" is unsupported.

# 2. The online pivot during the pandemic

According to the Instructure case study, at the outbreak of Covid in 2020, CityU used Canvas to move to a fully online teaching model within 8 days^※. This rapid turnaround owed much to the fact that the LMS migration had been completed back in 2015, and it also reflected the University's habit of building mobile learning into its digital-education planning — a system migration carried out five years earlier paid off as an "8 days to fully online" response time when the pandemic hit.

What made "8 days" possible, it is worth noting, was that the foundation was already in place: a cloud-hosted, elastically scalable SaaS platform, plus the integration work that had already wired the whole university's courses and enrolment system into Canvas. In other words, the real work was done between 2015 and 2019; the pandemic simply pushed the system to full load. This pattern of "laying pipes in peacetime, opening the sluice in an emergency" also helps explain why so many Hong Kong universities moved online relatively smoothly at around the same time — their underlying platforms were mostly outsourced to mature cloud providers, so scaling was a configuration problem rather than a rebuilding problem.

What moved online was not just "lecturing" but "assessment" — the trickiest link. According to guidance from CityU's e-Learning team for the 2020/21 academic year, instructors were directed to run online examinations using Canvas's Quizzes and Assignments functions^※ — converting paper-and-pencil tests into timed, randomly drawn, auto-markable online assessments. Add Zoom invigilation, Panopto lecture recordings and Turnitin plagiarism checks, and CityU had in effect moved the entire "teach, learn, assess" cycle onto the cloud during the pandemic. This forced full-scale drill also meant that many digital tools previously treated as mere "supplements" settled into normalised teaching infrastructure afterwards.

# 3. The teaching-tool ecosystem around Canvas

For CityU, Canvas is less a "course platform" than a hub plugged into a range of teaching tools. According to the tool list on CityU's digital-learning support pages, the common tools integrated with Canvas and used by teachers and students include at least:

• Panopto (lecture videos): CityU's official lecture-capture and video-delivery platform. Instructors record lectures or teaching videos using a computer and webcam, upload them to the Panopto server, and deliver them to students for viewing or review through the assigned Canvas course site^※; students can also use it to submit video assignments. This means a missed lecture no longer has to stay missed, and lectures settle into reusable assets.
• Turnitin (originality checking): scans assignments and generates originality reports, flagging potential plagiarism to teachers and students^※. Teachers create plagiarism-checked assignments, students upload documents for similarity comparison — the digital end of CityU's academic-integrity machinery. With the spread of generative AI in particular, such tools have become one of the technical reference points for defining "quotation / assistance / plagiarism".
• Zoom (video conferencing): CityU provides Zoom as its video-conferencing solution (institutional domain cityu.zoom.us), supported by CSC; Zoom recordings can also be fed back into Panopto for delivery.
• Grammarly / Google Classroom et al.: CityU also offers Grammarly writing assistance^※ through the "My Apps" dashboard, and lists Google Classroom as an alternative platform with basic announcement, assignment, quiz and discussion functions.

What makes these tools sit "seamlessly" on Canvas is unified identity and single sign-on: as noted in the previous section, Canvas and Microsoft 365 are both Category A systems connected via SSO. A student authenticates once with their EID and can then launch Panopto recordings, Turnitin checks and online quizzes from inside Canvas, without creating a separate account for each tool. For teachers and students, the "tool ecosystem" therefore collapses experientially into one thing — open Canvas, and everything else is in there.

This combination of "LMS as hub + lecture-capture/plagiarism/conferencing/writing tools as satellites" makes up the everyday teaching toolkit of CityU staff and students; during the pandemic, it was precisely this whole satellite system — not just Canvas alone — that was pushed to the front line at once.

The tool ecosystem also hides a strand that runs into the generative-AI-and-teaching question. Plagiarism-detection tools like Turnitin were originally aimed at "copy-and-paste" plagiarism; once GenAI can produce fluent, original-sounding paragraphs at a keystroke, "low similarity" no longer equals "the student wrote it themselves", and the meaning of the plagiarism check is rewritten — the tool itself has to update (adding AI-writing detection), and the definition of "what counts as compliant use" is forced up from the technical layer to the policy layer. This strand is the thread that the final section of this article pulls on: the more powerful the digital tools, the more the rules around them need to be redrawn by people.

# 4. Identity and login: EID, single sign-on and multi-factor authentication

The "key" to CityU's digital world is an EID (Electronic ID) and password — from Canvas and email to the course-registration system, nearly all university-level services use it as the single credential. Around this key, CityU has built an access layer of single sign-on (SSO) plus multi-factor authentication (MFA).

According to CityU's Information Technology Services, MFA adds an additional verification layer to account login^※, and its coverage falls into two categories: Category A covers everyday systems connected via SSO, such as Microsoft 365, Google Workspace, AIMS, Canvas, CityUHK Portal, the Mobile App and CityUHK Pay^※; Category B always enforces a second verification step for sensitive systems such as VPN, Fortinet, CyberArk, LaserFiche and Remote Desktop Gateway^※. Available verification methods include mobile apps such as CityU Authenticator, Okta Verify and Google Authenticator; users may choose "do not ask again" on trusted devices, but verification is still required on every session in incognito/private browsing mode.

Behind this design of "one EID + single sign-on + tiered MFA" lies a trade-off between convenience and security. Single sign-on saves the hassle of typing passwords across a dozen systems, but it also means that if an EID is compromised, an attacker can potentially hop from one system to another — which is exactly the case for MFA: even if the password leaks, without the second factor there is no entry. Putting high-risk systems such as VPN and privileged access into Category B, where verification is always mandatory, places the thickest layer of protection at the most critical doorways.

The exact scope of MFA enforcement, the available methods and the default switches are adjusted year by year; this article records only the architectural facts (the A/B two-tier division, mobile apps as the primary second factor). Multi-factor authentication is now standard practice across Hong Kong universities to defend against phishing and credential-stuffing attacks; CityU's approach is a tiered strategy of "on-demand for everyday systems, mandatory for sensitive ones".

# 5. Everyday digital gateways: Portal, AIMS, announcements and CityUHK Mobile

If Canvas is "the place where you have classes", then a handful of other systems make up the administrative and information gateways that CityU students deal with daily. According to CityU's IT guidance for student orientation, these "essential web applications" fall roughly into four groups:

• CityUHK Portal (campus portal): a personalised aggregated entry point logged into with the EID, gathering frequently used functions and the latest information in one place, including library resource search, sports-facility booking and a customisable dashboard^※.
• AIMS (Administrative Information Management System): the system that carries core academic-administration functions — course registration, grades, student status — and the upstream source of enrolment lists in Canvas course sites: student registration and group records are updated in AIMS first, then synchronised to Canvas.
• CAP (CityUHK Announcement Portal): the single publication channel for university-, faculty- and department-wide announcements; the system sends a "daily announcement digest" by email^※ each day, which the University asks students to check daily.
• CityUHK Mobile (mobile app): the iOS and Android campus super-app, providing access to announcements and everyday systems, and doubling as an MFA second-factor device — one phone that is both a "screen for notifications" and a "key for identity verification", collecting scattered entry points into a single handheld app.

Together with Canvas and email, these four systems constitute CityU's digital everyday: log in once with your EID — course registration in AIMS, classes in Canvas, announcements in CAP, and almost everything else in CityUHK Mobile. Unified identity, divided interfaces: a typical modern campus IT architecture. AIMS matters especially: from add/drop, checking grades and GPA, viewing exam timetables to printing transcripts, the entire academic-administration workflow runs through it, and it is the upstream source for Canvas lists, grading and enrolment data — which is why a single change to course enrolment shows up on both the AIMS and Canvas ends. Payments, too, have gone digital: the University runs CityUHK Pay, an e-payment channel linked to unified login and multi-factor authentication, so tuition and hall fees no longer require a trip to a counter. For new students, "learning to use these systems" is close to lesson one of university life — the orientation IT guide calls them "essential web applications" precisely because campus life jams without any one of them.

# 6. The Computing Services Centre and teaching laboratories

CityU's IT services are delivered mainly by Information Technology Services and the Computing Services Centre (CSC)^※. The CSC is CityU's central computing service provider, responsible for supplying computing facilities and technical support across the University, covering most aspects of campus computing and networking. CityU grew out of the Hong Kong City Polytechnic, founded in 1984^※ — an institution strong in engineering, business and computing from birth — and its central computing services grew with it from polytechnic to research university, expanding from the early central computer rooms and teaching labs into today's multi-layered landscape of "teaching labs + cloud platforms + high-performance computing". The CSC's reach is broad: email accounts, software licensing, teaching laboratories, printing, VPN, networking and high-performance computing — the entry point for nearly all university-level IT services sits here. For public computing resources in teaching and learning, the verifiable items include:

• Teaching laboratories and printing: the CSC runs 10 teaching studios in the teaching-studio area of the Li Dak Sum Yip Yio Chin Academic Building (LI)^※, equipped with high-specification computers; it also provides colour printing, fast printing and network printing. These labs carry hands-on courses in programming, statistics and design that need dedicated software and computing power, and double as public study and workstation space during exam season — for students who cannot bring their own high-end machines, an open lab can be the basic guarantee that coursework gets done.
• Library learning commons: the "The Oval" in the Run Run Shaw Library is fitted with over a hundred computer workstations, with software covering statistical analysis and programming languages (see 〈Run Run Shaw Library and the Indra and Harry Bang Gallery〉) — library computers at CityU are not just terminals for looking things up but workstations for running code and doing analysis, forming the campus's public computing network together with CSC's teaching labs.

This combination of "teaching studios + library workstations + central software licensing" means CityU students can complete the overwhelming majority of their coursework computing without owning a high-end machine. And when the computing demand crosses the scale of "one good computer", the next section's high-performance computing cluster takes over.

# 7. High-performance computing: the CityU Burgundy cluster

For heavy research computing, CityU operates a central high-performance computing (HPC) cluster, CityU Burgundy. According to the CSC, the system provides large-scale computing power, high-capacity storage and specialised software, supporting the computational research of over 700 researchers, students and professors across the University^※; users access it through an HPC account application.

On specifications, according to an HPE press release from April 2022, Burgundy is built from HPE Apollo 2000 and Apollo 6500 Gen10 Plus systems, with 328 AMD EPYC 7742 processors, 56 Nvidia V100 and 8 Nvidia A100 80GB tensor-core GPUs^※; when CityU announced the system's launch in 2020, it said its theoretical peak performance was 1.1 petaflops^※ — the most powerful among higher institutions in Hong Kong and Macau. Trade media DCD reports that the machine spans eight racks in all^※. Compared with CityU's earlier HPC resources, the new cluster delivers roughly a 10-fold speed increase for HPC and AI workloads^※; the University cited, by way of example, a quantum-chemistry study in which turnaround time was cut by a factor of three to seven. Application areas cover modelling and simulation in biomedicine, quantum chemistry, and the social and behavioural sciences.

In terms of usage, Burgundy supports Singularity containers: users can upload their own custom images, or ask the CSC to help set up the computing environments their research needs — allowing researchers from different disciplines and different software stacks to share GPU capacity on one cluster without each maintaining their own environment.

Why would a mid-sized university build its own petascale cluster with over a hundred training cards? The answer lies in the word "sharing": instead of each research group buying its own machines piecemeal and leaving them underused, the capacity is pooled into a single "university-level compute pool" allocated on demand to more than 700 users. Tensor-core GPUs such as the V100 and A100 are particularly suited to deep-learning training, which made Burgundy arrive at just the right moment as generative AI and large-model research heated up — when algorithm research grows ever hungrier for compute, a central GPU cluster is, in a sense, a research university's "infrastructure ticket" to the AI age. This sits alongside CityU's sustained push into data science and computational disciplines (see 〈College of Computing〉): the college trains the people, the cluster feeds the compute.

GPU models and counts on the cluster change with subsequent expansion (published reports also mention newer cards such as the A40 being added); this article takes the build specification from the 2022 HPE press release, and the currently installed configuration should be checked against the CSC's latest pages. Burgundy also falls under research support, and its public pages give no uniform external charging or quota specification; this article makes no specific record of these.

# 8. Campus network and eduroam

On connectivity, CityU provides campus-wide wireless, VPN (virtual private network), and the international academic roaming network eduroam. CityU joined eduroam in 2008^※ — at any eduroam member institution worldwide, staff and students can connect to the SSID "eduroam" for free using their CityU Wi-Fi credentials, with no advance registration, covering member institutions in over 100 countries/regions^※. Conversely, visitors from other institutions on campus can do the same with their home accounts — the "configure once, roam the world" promise of eduroam.

Off campus, CityU also lists commercial and public Wi-Fi as options: according to its official pages, students can use networks such as CSL Wi-Fi (over 23,000 hotspots across Hong Kong) and the government's Wi-Fi.HK (covering all 18 districts)^※. For a university as internationalised as CityU, with staff and students constantly crossing borders, eduroam is especially practical: a CityU student going on exchange abroad lands on the host campus and connects seamlessly, no temporary account required (see 〈Careers and the exchange student experience〉 for the exchange mechanisms).

On campus and for remote access, CityU provides campus-wide wireless plus a VPN (virtual private network) for staff and students to securely access internal resources (such as library databases and internal systems) from off campus; as noted above, VPN is a high-risk entry point with MFA always enforced. Take the three together — campus wireless, off-campus VPN, cross-institutional eduroam — and they cover the typical scenarios of "surfing on campus, reaching the intranet from home, roaming on another campus", completing the connectivity picture for CityU staff and students.

Campus wireless standards, VPN clients and hotspot counts are technical details updated year by year; this article records only stable institutional facts such as the year eduroam was adopted (2008) and the roaming mechanism.

# 9. Email, Microsoft 365 and cloud office tools

CityU's email and cloud-office provision is built around the Microsoft cloud:

• Student email: students use university email accounts on the domain @my.cityu.edu.hk^※ (format [email protected]), hosted on the Microsoft 365 cloud mail system, which serves as the official communication channel between CityU and its students; student mailboxes have around 100 GB^※ of capacity.
• Free Office applications: full-time and part-time students at associate-degree level and above can use Microsoft 365 Apps for free, installing Word, Excel, PowerPoint, Outlook, OneNote and more on up to 5 PC/Mac and 5 mobile devices^※; the licence must be verified online every 30 days, and it lapses on graduation, at which point the software must be uninstalled.
• Alumni email: alumni also have a Microsoft 365-based email service, with roughly 50 GB of mailbox capacity.

This gives CityU staff and students the Microsoft 365 / Office ecosystem — mail, Teams collaboration, OneDrive cloud storage and more — as their everyday learning and work platform. A few points are worth noting. First, the university email is explicitly positioned as the official communication channel: grades, payments, administrative notices and other important matters tend to arrive through it, and a student who neglects it may miss critical information — which is why CityU keeps stressing "check your email daily, check CAP daily". Second, the account has a lifecycle: while enrolled, students enjoy a 100 GB mailbox and free Office licences; after graduation they convert to an alumni mailbox of about 50 GB and lose the Office licence — a two-stage "student–alumnus" service gradient.

Pushing mail, identity, collaboration and online storage onto the same cloud means students can walk across the whole university on a single EID, with seamless continuity across devices; the cost is deep dependence on a single vendor — a trade-off Hong Kong and universities worldwide have been wrestling with in recent years. Microsoft 365 Education has been tightening its storage caps in recent years, and many universities, CityU among them, have had to re-plan mailbox and OneDrive quotas. As the age of "free unlimited storage" closes, balancing teaching needs against compliance retention within finite quotas has become the new shared problem for IT departments everywhere.

# 10. Generative AI and teaching

Faced with the impact of generative AI (GenAI) tools such as ChatGPT, CityU's approach is "acknowledge the utility, regulate the use":

• CityU has issued the Guidelines on the Use of Generative AI Tools in Teaching and Learning^※, applying to all teaching-related activities and assessment tasks. The guidelines state that the University recognises the usefulness of GenAI tools, encourages their appropriate use in teaching, with a view to cultivating students' creativity, critical thinking and communication skills and advancing CityU's "Graduate Outcomes", while emphasising that use depends on specific context and manner.
• The guidelines are managed by version and by audience: CityU provides separate versions for teachers and students, revising them each semester (for example, covering through the 2025 Summer Term, with a new version taking effect from Semester A of the 2025/26 academic year onward^※), and offers guidance that distinguishes between formative and summative assessment.
• Transparency and disclosure is a core principle: on the teaching side, CityU requires instructors to disclose any AI-generated content that appears in teaching materials or classroom activities (by annotation, footnote or oral explanation), and not to outsource whole sets of materials to GenAI, ensuring the content reflects the instructor's own professional judgement and pedagogical design. CityU also provides resources such as the CityUHK Prompt Library to help staff and students use these tools well.
• On the staff side, the Talent and Education Development Office has run training programmes such as "Building AI Knowledge and Skills for Curriculum Development" to help instructors build AI literacy into course design.

Zooming out, CityU's response to generative AI is not an isolated policy document but a natural extension of its years-long bet on computing. Well before ChatGPT hit public consciousness, CityU had set up a School of Data Science in 2018 and consolidated a College of Computing in 2024, elevating data and AI to university-wide disciplinary priorities. When GenAI struck at the teaching front line, it had, ready to hand, the compute (the Burgundy cluster), the platforms (Canvas and the surrounding tools), and the organisational habit of folding new tools into the curriculum. This explains why CityU chose "acknowledge the utility, encourage appropriate use" rather than pure defensiveness — for a university that emphasises computing and data, shutting AI out of the door would run against its own positioning. The real difficulty therefore lands at the execution layer: how to draw a clear line, course by course, between "encouraged use" and "protecting academic integrity".

The specific provisions of the guidelines are revised year by year; the latest official version prevails. The permitted scope of generative AI in assessment (fully prohibited / use limited / use encouraged) is generally left to individual courses to state, as a course-level arrangement. This two-tier structure of "institutional direction at the top, course-level execution below" runs in the same vein as CityU's sustained investment — the School of Data Science in 2018 and the College of Computing in 2024.

# 11. Summary

CityU's digital education infrastructure is built on Canvas (LMS) + Microsoft 365 (mail and collaboration) + EID single sign-on + eduroam/campus wireless (connectivity) as its backbone, with teaching tools such as Panopto, Turnitin and Zoom on the outside, and multi-layered computing capacity from the CSC's teaching labs, library workstations and the Burgundy high-performance computing cluster underneath. In the AI age, CityU responds to generative AI's impact on teaching and learning with institutional guidelines and staff training. Pull the strands of this article together and a clear pattern emerges: identity centralised (one EID + SSO + tiered MFA), platforms outsourced (LMS, mail and collaboration all hosted by mature cloud providers), compute kept in-house (university-level clusters like Burgundy stay on campus), policy turning (on generative AI, from "defence" to "acknowledge the utility, regulate by context") — four lines, each with its own trade-offs, yet all pointing to the same pragmatism: buy what can be bought, outsource what can be outsourced, and build and manage in-house only what must be held in one's own hands (compute and identity). The overall orientation is close to that of most Hong Kong universities — platforms outsourced to mature cloud providers, identity consolidated into a single EID with multi-factor authentication, and policy moving from "ban" to "regulated use". The library's learning commons "The Oval", equipped with statistical analysis and programming tools (see 〈Run Run Shaw Library and the Indra and Harry Bang Gallery〉), echoes the computing infrastructure described here, together giving CityU its distinctively computation-heavy character — "even the library computers can run code, and behind it all hangs a petascale cluster" (for institutional context see 〈The Hong Kong higher-education landscape〉).
