Frequently Asked Questions for Server Apps

16/02/2018 Stuart Moore

Media

Are you able to create Containers for applications where there is no media?

Yes - please contact Cloudhouse Sales, and Pre-Sales Consultant for further details.

Services

Do Containers support applications that use Windows Services?

Yes - refer to How to enable application services in a Container (Service)‍ .

Server Names

What happens if my application architecture depends on a fixed server name?

If required, Cloudhouse Containers can redirect network APIs, ports and IP addresses to overcome an application's dependencies on specific network addresses and names, for example you need the application to communicate with a different server name even though it is hardcoded to communicate with a different name.  Please contact Professional Services representative for details.

Databases

Do Containers support databases, for example SQL Server and Oracle?

Yes - databases, and database applications can be packaged into Containers, including SQL Server 2005. Database applications can be packaged into an application, packaging the database into a Container is optional - customers can continue to run the database itself natively. Connections from an application in containers to a remote database, or connections from applications to a remote database in a Container are not affected.

Server Operations

What provisions do I need to make in maintenance schedules, reboot and patching procedures?

None, Containers require no change to reboot procedures or maintenance schedules. The application receives the OS shutdown request as normal, and the application shutsdown gracefully before the server reboots as part of maintenance reboot, or operating hot fix, service patch or update.

How do you apply updates, hot fixes to an application?

Refer to Updating, Editing and Maintaining Containers‍ 

Monitoring Applications in Containers

Server based applications running in Containers can be monitored with the same monitoring tools used to monitor natively installed application e.g.  BMC or SCOM will see exactly the same process names used by the application, the process will appear as a child process of AppAcceleratorV.exe.

Business Continutity

Do Cloudhouse Containers affect an application's provision for High Availabilty or Disaster Recovery?

No, Containers do not impact HA or DR design, planning or architecture - the application continues to function in exactly the same way as the natively installed application, and tools like VMware's Site Recovery Manager continue to operate without requiring changes to their plans.

Considerations for data backup and archiving

There is zero impact on backup and archiving schedules, or implementation, for applications or their dependent databases. Cloudhouse do recommend that the Containers are backed up so that they can be recovered in the event of server failure.
