This system enables research institutions to lease, sub-lease or claim bare-metal machines and add or remove them from the OpenShift deployment without any impact on the OpenShift performance. In this way, we enable an elastic infrastructure layer along with OpenShift, which can reduce the operating cost of computation. </span></div><br class=""><div style="line-height: 1.38; text-align: justify; margin-top: 0pt; margin-bottom: 0pt;" class=""><span style="font-size:11pt;font-family:Arial;font-weight:700;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap" class="">How do I get access to the ESI or get in touch with the team for a demo?</span></div><div style="line-height: 1.38; text-align: justify; margin-top: 0pt; margin-bottom: 0pt;" class=""><span style="font-size:11pt;font-family:Arial;font-variant-numeric:normal;font-variant-east-asian:normal;vertical-align:baseline;white-space:pre-wrap" class="">If you are interested in getting to know more about the ESI project, and the project’s roadmap or want to be part of the development activities, you can contact us by sending an email to </span><a href="http://esi@lists.massopen.cloud/" style="text-decoration-line:none" class=""><span style="font-size:11pt;font-family:Arial;background-color:transparent;font-variant-numeric:normal;font-variant-east-asian:normal;text-decoration-line:underline;vertical-align:baseline;white-space:pre-wrap" class="">esi@lists.massopen.cloud</span></a><span style="font-size: 11pt; font-family: Arial; background-color: transparent; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;" class="">.
