Use Redis instead of Memcached?

[brandontamm]

Have you looked at using redis instead of memcached?

One less service with no performance impact as far as I know? Thoughts? I tried to adapt the PHP build to not include the memcached portion but I think there are more pieces interwoven into the project....

My initial attempt resulted in error - SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known

Also, any downsides to replacing varnish with NGINX caching instead?

On Magento 1.9, I personally use Redis for Sessions, Cache and Full Page Cache. I have a seperate containers per type since Redis is not threaded.
