Test №7 - 8
Introduction:
- Test 7: The Baseline MCPT Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 6 Instance Type: c7g.large, 3 of them for okapi service and other 3 for mod-cources, mod-sender, mod-tasks-list, mod-gobi, edge-dematic, mod-erm-usage, mod-eusage-reports, mod-notify, mod-data-import services and 10 Instance Type: r7g.xlarge for others modules. Fixed Load (average case without DE_Exporting MARC Bib records custom workflow, DE_Exporting MARC Bib records workflow, and OPIH_/oai/records workflow) MOBIUS test was run (Repeat Test 6).
- Test 8: The Baseline MCPT Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 6 Instance Type: c7g.large, 3 of them for okapi service and other 3 for mod-cources, mod-sender, mod-tasks-list, mod-gobi, edge-dematic, mod-erm-usage, mod-eusage-reports, mod-notify, mod-data-import services and 10 Instance Type: r7g.xlarge for others modules.

Introduction:
- Test 9: The Baseline MCPT Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 6 Instance Type: c7g.large, 3 of them for okapi service and other 3 for mod-cources, mod-sender, mod-tasks-list, mod-gobi, edge-dematic, mod-erm-usage, mod-eusage-reports, mod-notify, mod-data-import services and 10 Instance Type: r7g.xlarge for others modules. Fixed Load (average case without DE_Exporting MARC Bib records custom workflow, DE_Exporting MARC Bib records workflow, and OPIH_/oai/records workflow) MOBIUS test was run (Repeat Test 7 after Terminate Instances r7g.xlarge).
- Test 10: The Baseline MCPT Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 6 Instance Type: c7g.large, 3 of them for okapi service and other 3 for mod-cources, mod-sender, mod-tasks-list, mod-gobi, edge-dematic, mod-erm-usage, mod-eusage-reports, mod-notify, mod-data-import services and 10 Instance Type: r7g.xlarge for others modules. Fixed Load (average case) MOBIUS test was run (Repeat Test 8 after Terminate Instances r7g.xlarge).
Objective: The objective of these tests was to validate the consistency of performance observed in Test 7 and Test 8. This was achieved by repeating the same configuration and applying new random task locations per instance after terminating the r7g.xlarge instances.
Results: Performance result were worse on 50% for several workflows after terminating the r7g.xlarge instances and applying new random task locations per instance.

Test №11
Introduction: The Baseline MCPT Environment configuration was applied, and CPU=2 was set for all services, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 11 Instance Type: r7g.xlarge for others services. Fixed Load (average case) MOBIUS test was run.
Objective: The goal of this test was to replace three c7g.large instances with one additional r7g.xlarge instance for all services, while retaining three c7g.large instances specifically for the okapi service.
Results: The performance was worse compared to when we used the additional three c7g.large instances for services with smaller workloads.
