Most tertiary education institutions operate using a student information system (SIS) built on one of three models: on-premises, managed cloud, or Software as a Service (SaaS).
While all three approaches support core sector functions, the differences between them become increasingly evident as institutions start to focus on data-driven decision-making, scalability, automation, and innovation.
Rizad Rahim, Senior Solutions Consultant, APAC, Ellucian, explores the key distinctions between on-premises vs managed cloud, and SaaS SIS models, and explains why institutions are shifting to SaaS to reduce the burden of legacy systems, support innovation, and build future-ready technology ecosystems.
On-Premises SIS: Institution-Managed with Heavy Operational Burden
An on-premises SIS is located on campus, within an institution’s own infrastructure. It runs on local servers and is fully managed by internal IT teams, meaning the institution is responsible for everything from maintenance and upgrades to security and system performance. While this may appear to offer greater control, it can often place pressure on internal resources and slow the pace of innovation.
Institutions using on-premises systems must focus on maintaining legacy infrastructure, leaving less time to automate workflows, improve data sharing or enhance the student experience. IT teams also have less capacity to support broader institutional strategic priorities, whether these are to address student retention, introduce new learning pathways or deliver better academic outcomes for learners.
Legacy on-premises systems can become more costly over time as institutions are responsible for upgrading their own infrastructure. Additional investment is also needed to scale systems, even if the extra capacity is only needed temporarily, such as during the busy registration period.
Managed Cloud SIS: Reduced Infrastructure, but Ongoing Complexity
Managed cloud SIS solutions move IT infrastructure off campus and into a cloud-hosted environment, but they do not fully remove operational responsibilities from internal IT teams.
With this model, the cloud provider typically manages the underlying infrastructure that runs the system, but institutions remain responsible for system configuration, testing, upgrades, and some aspects of performance management. IT teams therefore remain actively involved in how the SIS operates, even though the system is hosted in the cloud.
Managed cloud is a step forward from on-premises systems, but it does not deliver the full potential of automation or operational simplicity that SaaS provides. The ability to scale is also more complex with this model. While it can support increased demand, adjustments to performance often require input from internal IT teams or coordination with the vendor. This is still more flexible than on-premises systems, but it introduces an additional step that is completely removed in a fully SaaS environment.
Institutions will come up against limitations with integration too. While managed cloud solutions can connect systems and bring data together, they will not always provide access to real-time data or student touchpoints. This can make it harder for institutions to build fully connected digital experiences or automate processes across different parts of the student journey.
SaaS SIS: A Fully Managed Platform Built for Innovation
A SaaS SIS is a fully cloud-based model that completely removes responsibility for system development, performance, security and ongoing maintenance from institutions. This allows them to focus on their strategic priorities, innovation, and delivering the best possible student experience.
The Ellucian Student SaaS ecosystem is built for tertiary education. It provides continuous enhancements and AI-enabled insights to help institutions respond more quickly to changing expectations, improve efficiency, and deliver better outcomes across the student journey. Designed around the specific needs of the sector, it reflects the requirements of institutions, their students, and staff.
Embed AI into Every Interaction
With SaaS, AI is not layered onto systems. It becomes part of the natural flow of every activity that takes place in an institution.
Students can ask AI digital assistants any question and get an answer straightaway, with responses tailored automatically to their individual study history, enrolment status, and academic progress. Questions about course options or changes in study plans are handled in context, with responses that reflect the student’s current academic pathway rather than simply displaying generic information.
Advisors can instantly see details such as students’ course information, housing status, recent engagement in learning and interactions with academic and welfare teams, without searching for it. This ensures discussions are focussed on the right priorities from the outset.
AI can also flag emerging trends, including individual students or cohorts where engagement is falling, or staffing constraints in subject areas, so that action can be taken to address issues before they have an impact on learning.
Automate Routine Processes Across the Student Journey
SaaS allows institutions to automate many of the manual administrative processes that traditionally slow down the student experience.
Instead of requesting information, students can instantly access information such as financial statements, course deadlines or details of clubs and trips directly from their own workspace. Instead of submitting requests to administrative teams and waiting for documents to be processed manually, students can select the relevant study period and generate documents instantly through connected workflows.
These processes are powered through integrations and APIs that pull information directly from the SIS in real time, reducing duplication and removing the need for staff to manage routine requests manually.
Create the Foundation for Data-Driven Decision-Making
SaaS gives institutions access to more complete and connected information on the whole student journey, helping teams work from a consistent view of information across the institution.
This supports more informed decision-making across areas such as student retention, support planning, and academic progression. Institutions can also identify patterns and trends earlier and respond using current operational data rather than relying on delayed reporting cycles or manually updated records.
Strengthen Security and Reduce Institutional Risk
With SaaS, security, updates, patches, and data protection are all managed and governed within the cloud environment and applied continuously across the platform.
This creates a consistent, system-wide compliance framework where security protections are deeply embedded into the system and maintained as part of the ongoing service delivery, rather than being on a busy IT team’s to do list.
Add New Functionality and Innovate Continually
SaaS allows new functionality to be delivered continuously through the platform, rather than implementing large upgrade projects that need to be planned, tested, and delivered in-house. It provides the ideal technical environment for a constant pipeline of innovation, so institutions can adopt new capabilities as they become available rather than waiting for major system releases.
This means that as student expectations and institutional priorities evolve, the platform can evolve seamlessly alongside them. It also enables institutions to modernise incrementally as their needs change.
Support Institutional Growth Without Adding Operational Complexity
During high-volume periods such as enrolment or assessment, systems scale up automatically to support large increases in student activity without manually adjusting infrastructure or managing additional hardware capacity behind the scenes.
This gives institutions the flexibility to expand digital services, support growing student populations, and introduce new student experiences without needing to continually scale internal infrastructure.
The Future of Tertiary Education is Built on SaaS
Institutions currently operating on-premises or in managed cloud environments are increasingly recognising SaaS as a decisive shift away from the constraints of legacy systems toward a more adaptable operating model. SaaS enables institutions to focus more directly on innovation and student success, underpinned by the latest data security and compliance requirements.
SaaS helps institutions to keep pace in a world where tertiary education moves fast. With AI-enabled decision-making, automation, and a fully connected ecosystem, institutions can adapt quickly to change and operate with greater agility across the student lifecycle.
