Solving the Google Workspace 100 TB Storage Limit for Research Institutions Using AWS S3

Are you struggling to accept the storage limit policy changes for Google Workspace for Education?

Does the newly imposed 100 TB storage limit have you scrambling to find a new home for your data?

Don't want to deal with the headaches of building your own access and collaboration interface for S3?

In the modern era, research institutions are generating and analyzing larger amounts of data than ever before. This trend is set to continue, as new technologies like AI, machine learning, and big data analytics continue to evolve. As a result, there has been a growing need for research institutions to store and manage vast quantities of research data. However, Google Workspace for Education has recently imposed a limit of 100TB across all end-users, creating a serious problem for research institutions with larger data sets.

Why the Limit of 100TB is a Challenge for Research Institutions

Research institutions generate vast amounts of data that needs to be stored, managed, and accessed by teams of researchers, faculty, and students. However, Google Workspace for Education has recently imposed a limit of 100TB across all end-users. This is a challenge for institutions with larger data sets, as it is simply not enough storage to meet their needs.

The 100TB limit might be sufficient for some institutions, but for those who generate large amounts of data on a regular basis, this limit presents a significant problem. Institutions will have to either find alternative storage solutions, delete data or purchase additional storage, which is not only time-consuming but also expensive. In addition, researchers and students might have to spend time migrating data between platforms, which can be a tedious and cumbersome process. As of this writing, Google limits data transfer to 750 GB per day. So, if Google Workspace holds the only copy of your data, it will take more than 3.5 years to extract the first 100 TB!

CentreStack Feature Highlights


CentreStack integrates with a range of storage services, including AWS S3. This integration allows institutions to leverage the benefits of Amazon’s Simple Storage Service while still providing secure and controlled access to data sets.


CentreStack is highly scalable and can handle large data sets without compromising performance. This scalability is essential for research institutions that need to handle large amounts of data.

Data Sovereignty

You maintain control of your data. You choose where it's hosted. You can move it all to the cloud or maintain a locally synchronized copy.

Using AWS as a File Server

CentreStack, with the AWS API integration, adds secure remote access and file sharing, disaster prevention, and recovery to file server on-premises with easy cloud migration to Amazon Web Services.


CentreStack combines file servers and AWS for secure remote access and file sharing.


CentreStack leverages AWS as a central cloud file repository with version control, file change history, and audit tracing to provide business continuity for file servers on-premises.


CentreStack sets up a hybrid deployment between local file servers and AWS that can be seamlessly converted to AWS only. The result is a cloud file server on top of AWS instead of on-premise.
