Everything is a trade off in system operations.
Over the past 18 years I have been using the following techologies / softwares:
chef, puppet, ansible, cfengine, terraform, packer configuration management. mcollective orchestration, devops attitude.
jenkins, gitlab-ci, bamboo build automation,
pfsense, brocade zxtm, amazon web services, elastic load balancers,
xymon, nagios, icinga2, cacti, smokeping, pingdom, TIG (telegraf, influxdb grafana), TICK (telegraf influxdb chronograf kapacitor)
elasticsearch, kafka, zookeeper, mssql, mysql, postgresql, cratedb, aurora, redis.
aws ec2, openstack, virtualbox, kvm, ovirt, vagrant, terrraform.
debian / ubuntu, but Redhat / CentOS are preffered OS.
ipsec / racoon / strongswan / pfsense
