- centOS 7
- centOS 7 hasn't been used by the Mayo team (as of yet.)
- There is much interest in the automated environment setup provided by Docker.
- Sarah indicated that it would NOT be an upgrade on the existing web servers. They would recommend this for new servers.
- As of Sept 30, centOS 7 is to the current supported catalog at NCI. They still provide previous centOS 6 for several years. Redhat dates 2020 for centOS 6 and 2024 for centOS7.
- Scott also suggested the use of a Sonatype Nexus server to distribute Docker artifacts. NCI currently provides a Nexus server. However Docker artifacts are fairly large and infrastructure would need to be considered.
- Additional Docker discussion later in the week. There are 2 use cases - deploying at NCI and supporting other users (setup).
- MariaDB is a MySQL fork. Advantages aren't known at this time. The NCI database team would need provide support if MariaDB were to be used. This may be in the future Tech Catalog.

- Gilberto shared that for the Protege Project uses Java 8 - the only issues were around concurrency.
- Sarah indicated that there are other projects that are built with Java 8 and Java 8 and Tomcat 7. There is full support for Java 8 and Tomcat 7 at NCI. Sarah would need to know the exact version numbers.
- TODO: Scott to send Sara the version numbers for Tomcat.
- Kim can demonstrate an error with Java 8 and Spring 2.? Kim and Scott to discuss.
