Recent advances in cyber-infrastructure have enabled
digital data sharing and ubiquitous network connectivity
between scientific instruments and cloud-based storage infrastructure
for uploading, storing, curating, and correlating of large
amounts of materials and semiconductor fabrication data and
metadata. However, there is still a significant number of scientific
instruments running on old operating systems that are taken
offline and cannot connect to the cloud infrastructure, due to
security and network performance concerns. In this paper, we
propose BRACELET - an edge-cloud infrastructure that augments
the existing cloud-based infrastructure with edge devices and
helps to tackle the unique performance & security challenges that
scientific instruments face when they are connected to the cloud
through public network. With BRACELET, we put a networked
edge device, called cloudlet, in between the scientific instruments
and the cloud as the middle tier of a three-tier hierarchy. The
cloudlet will shape and protect the data traffic from scientific
instruments to the cloud, and will play a foundational role in
keeping the instruments connected throughout its lifetime, and
continuously providing the otherwise missing performance and
security features for the instrument as its operating system ages.
