I can optimize linux plesk server. This hourly includes the below things.
1. Server optimization which includes, installation of nginx
2 Installing and configuring CSF and LFD firewalls, which prevents from brute-forces.
3. Enabling php 5.6 as default for all websites. Plesk already started
started supporting multiple versions hence you don't have have to
worry about website working. If some website needs particular php
versions it can be changed via plesk for the account.
4. Removal of unwanted services in the server which eats more resources in the server.
for eg Drweb
5. Mysql optimization, optimization of mysql parameters.
6. Configuring backup via plesk. I can configure Local or remote FTP backup according to your requirement.
7. Automated Weekly scan using maldet or clamscan
8. Implementing cache mechanism for php, apc or xcache. I will be
installing one which suites more apt for current server configuration.
