That looks OK, but you may want to look into using
https://httpd.apache.org/docs/2.4/mod/mod_remoteip.html
You would have to set RemoteIPHeader to True-Client-IP and, since
Akamai to my knowledge doesn't publish a list of its source IPs,
consider some kind of authentication, e.g. basic auth
https://httpd.apache.org/docs/2.4/mod/mod_auth_basic.html to protect
the vhost from access without Akamai. Otherwise anyone would be able
to fake an arbitrary source IP in your logs.
