WHY
Cost Saving

WHAT
Reinstall ELL with new nodes types that will save money.
Consider Hibernating the cluster and only wake when required.
Possibly hibernate over the weekend even

HOW
See previous ELL JIRA

Following nodes were suggested:

• rightsize the type to r6g.xlarge (possible saving is 47%)
• rightsize the type to r7g.xlarge (possible saving is 44%)
• rightsize the type to r6a.xlarge (possible saving is 41%)
• rightsize the type to r5a.xlarge (possible saving is 41%)
• rightsize the type to r6gd.xlarge (possible saving is 40%)

For Hibernating, something like:
0 0 */30 * * /usr/local/bin/ocm resume cluster eng-long-lived
0 4 */30 * * /usr/local/bin/ocm hibernate cluster eng-long-lived
