Findings (MAC III - Administrative Sensitive)
The Apache HTTP Server, httpd, is an open source web server developed by the Apache Software Foundation. If you are upgrading from a previous release of Red Hat Enterprise Linux, you will need to update the httpd service configuration accordingly. This section reviews some of the newly added features, and guides you through the update of prior. A virtual machine instance on Google Compute Engine can be controlled like any standard Linux server. Deploy a simple Apache web server to learn the basics of running a server on a virtual machine.
