Subject [ANNOUNCE] Realhostip Service is Being Retired

Realhostip Service is Being Retired

Recently the Apache CloudStack PMC was informed that the Dynamic DNS service
that CloudStack currently uses as part of the console proxy will be disbanded this summer.
The realhostip service will be shut down June 30th, 2014, meaning users have approximately
3 months to mitigate this.

Prior to version 4.3, CloudStack used the service by default. With the release
of CloudStack version 4.3 the default communication method with the console proxy is plaintext

Who is Affected

CloudStack installations prior to version 4.3 that have not been reconfigured to use a DNS
domain other than for Console Proxy or Secondary Storage must make changes
to continue functioning past June 30th, 2014.

Steps You Need to Take

If you meet the criteria above, there are several options to prepare for realhostip retirement:

	• Set up wildcard SSL certificate and DNS entries: This method is already well supported
within prior versions of CloudStack.
	• Upgrade to CloudStack 4.3 and disable SSL: This is only recommended for development installations,
or private clouds that contain no information of importance.
	• Upgrade to CloudStack 4.3, set up static SSL certificate and configure load balancer
to point to the correct IP address: While this allows an administrator to skip setting up
the DNS entries from the previous option, it is a more advanced option as CloudStack 4.3 does
not support automatic load balancer configuration for the Console Proxy. It is hoped this
functionality will be available in future releases.
For instructions on how to set up SSL encryption for use with CloudStack console proxy, please
read the console proxy section of the CloudStack administration guide.

Additionally, if you will be using an SSL vendor who requires an intermediate CA chain to
be installed for proper SSL validation by web browsers, detailed instructions for configuring
the intermediate CA chain in CloudStack can be found here.

The Apache CloudStack security team does not recommend running a production cloud with either
the SSL certificate, or with no SSL encryption at all.
