Overview

The primary objective of testing was to evaluate the performance of the Baseline MCPT Environment configuration while attempting to optimize costs by adjusting instance types and reducing the number of instances. The tests were designed to compare the performance outcomes across different configurations, including variations in instance types and counts within multiple Auto Scaling Groups (ASGs). By systematically modifying these variables, the goal was to maintain or improve the performance observed in the baseline configuration while achieving cost efficiency.

Summary

Through a series of experiments involving different placement strategies, instance types, and total instance counts, we found that the performance remained consistent when using these two configuration:
- six c7g.large instances (three dedicated to the okapi service and three allocated to mod-courses, mod-sender, mod-tasks-list, mod-gobi, edge-dematic, mod-erm-usage, mod-eusage-reports, mod-notify, and mod-data-import services) alongside ten r7g.xlarge instances for all other services, with the CPU parameter set to 2 for all services.
- three c7g.large instances dedicated to the okapi service alongside five r7g.2xlarge instances for all other services, with the CPU parameter set to 2 for all services.
Notably, both environment configuration offers a 40% cost reduction compared to the existing setup, making it a more economical option without compromising on performance.
Configurations with three c7g.large instances for the okapi service and five r7g.2xlarge instances for all other services show the best performance across all experiments. So it will be more tests in this ticket.
Tests had 100% errors count for AIE_TC: Create Invoices, AIE_TC: Invoices Approve, AIE_TC: Paying Invoices, TC: Receiving-an-Order-Line, Unreceiving-a-Piece and Unreceiving-a-Piece Workflows because data was not regenerated.

Introduction: 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.

Objective: The goal of this test was to exclude several unstable workflows and observe whether their removal would have a noticeable impact on the performance of the remaining workflows. Specifically, by omitting the DE_Exporting MARC Bib records custom workflow, DE_Exporting MARC Bib records workflow, and OPIH_/oai/records workflow, the test aimed to assess if the stability and performance of the other workflows would improve under the same configuration.

Results: We observed minor performance improvements across almost all workflows. However, these improvements were not substantial. It appears that the observed effects are relatively small and can be attributed to a reduced overall load in the environment.

Methodology/Approach

Tests scenarios were started by JMeter script from load generator.

Baseline QCP1 Environment configuration: Parameter srs.marcIndexers.delete.interval.seconds=86400 for mod-source-record-storage, number of tasks to launch for service mod-marc-migrations-b was set zero. Instance type: m6g.2xlarge. Instances count: 10. Database db.r6g.xlarge, Amazon OpenSearch Service ptf-test: r6g.2хlarge.search (4 nodes).

Test 1: The Baseline QCP1 Environment configuration was applied, qcp1_MiniMaster.jmx script was run.
Test 2: The Baseline QCP1 Environment configuration was applied, qcp1_MiniMaster.jmx script was run (Repeat Test 1).
Test 3: The Baseline QCP1 Environment configuration was applied, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type: c7g.large for others services, qcp1_MiniMaster.jmx script was run.
Test 4: The Baseline QCP1 Environment configuration was applied, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type: c7g.large for others services, qcp1_MiniMaster.jmx script was run (Repeat Test 3).
Test 5: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type: c7g.large for others services, qcp1_MiniMaster.jmx script was run.
Test 6: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type: c7g.large for others services, qcp1_MiniMaster.jmx script was run (Repeat Test 5).
Test 7: The Baseline QCP1 Environment configuration was applied, and CPU=2 was set for all modules except CPU=2048 for mod-search, used two autoscaling groups, 1st with 3 Instance Type: c7g.large for okapi service and 5 Instance Type: c7g.large for others services, qcp1_MiniMaster.jmx script was run.
