What Is a Service?
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
A service is a set of one or more virtual machines that are deployed together and managed as a single entity
Service:
Is deployed by an administrator or end-user
Can contain several different components
Can be deployed to a private cloud or to a host group
Can have preinstalled roles, features and applications
Can contain multiple virtual machines working together on an application, such as a web application

5. What Is a Service Template?
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
Encapsulates all necessary components that are required to deploy and run a new instance of an application
Service template considerations:
Administrator creates service template in VMM
Application owner deploys a service based on the service template
App Controller or VMM console can be used to deploy service based on service template

6. Service Template Service template (multi-tier .NET applications)

7. Service Template Updates
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
Template-driven
Provide a single source of truth for service deployments
Use Upgrade Domains to limit disruption of service during updates
In-place updates
Change application or template settings without replacing OS image
Change memory, update application package
Image-based updates
Replace old OS image with new OS image
Reinstall the application and restore the state
(More notes on the next slide)

12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
Updating a Service
Exporting and Importing Service Templates

9. Creating a Service Template
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
Important considerations about creating service templates:
End users cannot create service templates
Service templates can include one or more tiers
Each tier can contain one or more virtual machines and applications
Add network components such as load balancers and logical networks to service templates
Use library resources to build service templates

10. Creating Deployment Configuration for Services
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
When deploying a service, you must create a service deployment configuration
Considerations for creating a service deployment configuration
Deployment configuration validates a service template and chooses a host
Deploy process is initiated from VMM console or App Controller
You can monitor the service deployment process from Jobs view and Event Viewer

11. Updating a Service Two ways to update services:
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
Two ways to update services:
Apply updates to an existing virtual machine
Known as an in-place update
Quicker way to apply an update
Good for application updates and VM configuration
Deploy new VMs with updated settings
Used to update operating system, apply service packs
Use upgrade domains to enhance service availability
Groups of VMs that are updated one at a time
Only one group taken down, updated, brought up, then repeats process on next group

Connecting an App Controller to Clouds

13. What Is an App Controller?
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
A self-service tool for end users that allows them to manage, deploy and view resources in clouds
Web-based, uses Internet Explorer to connect
Server requires IIS installation
Can manage Windows Azure subscriptions
Allows end users to manage, deploy and view resources in Windows Azure
Allows administrators to delegate authority to application administrators for certain cloud resources

14. Connecting an App Controller to Clouds
12: Managing Services in System Center 2012 R2 Virtual Machine Manager and App Controller
App Controller must be connected to VMM or Windows Azure or both
For VMM, you should provide the FQDN of the server
For Windows Azure, you need a subscription ID and password
Consider importing certificates from VMM
Administrator privileges are required to establish a connection
