7-8: Increased CPU and memory allocations are appropriate for handling higher loads.
18-18: Autoscaling disabled. Verify the impact on system performance and stability.Verification successful
Autoscaling disabled across multiple services as part of recent updates. The change in
memcached.ymlaligns with these updates. It's important to monitor the impact on system performance and stability as these changes roll out.

1-6: Volume set configuration is well-defined and suitable for general-purpose Redis instances.
10-28: Container settings and resource allocations are well-tailored for a basic persistent Redis setup.
30-33: Autoscaling disabled. Verify the impact on system performance and stability.Verification successful
Autoscaling is disabled across multiple service configurations (memcached, PostgreSQL, Redis). No issues or performance metrics indicating problems due to this configuration were found in the repository.
