Presentation given with co-presenter Alex Heneveld at the Cloudstack Collaboration Conference, Nov 30, 2012

1. Quality Control in a Cloudy World
CloudStack Collaboration Conference

2. Cloud is cool but …
• How do you determine whether a cloud is suitable for your
workload?
• How do you validate that it works as advertised?
• How do you ensure no short cuts have been taken
implementing it?
• Whatever your particular cloud strategy – private, public or
hybrid – these are serious questions
• Ones that you should address before you step off the kerb
• It’s all about the application, stoopid!!!

3. Commercial
• Cloudsoft’s Application Management Platform (AMP) …
• Supported version of the brooklyn open source project
• See http://brooklyncentral.github.com/
• Automates Application Deployment and Configuration
• Implementation details are abstracted into reusable blueprints
• Streamlines and enhances existing tooling
• Optimizes Application Runtime Management
• Driven by your technical and business policies
• Autonomic control plane
• Ensures Application Portability
• Frees the business to exploit a multi-provider strategy
• Avoids vendor lock-in

4. Brooklyn Key Concepts
• Entity
• Exposes sensor / effector interface plus where applicable pluggable
implementation
• Sensors and Effectors
• Reuse existing metrics and APIs for non-intrusive integration and
management
• Topology
• Entity wiring, groupings and management hierarchy
• Policy
• Governs application’s behaviour e.g. horizontal scaling
• Blueprint
• Captures an application’s initial topology plus policies that will change this
over time – CloudFormation and vApp templates on steroids
• Location
• Target environment for blueprint instantiation

6. Creating a Brooklyn Blueprint
In this walk through we show how easy it is to design
an elastic multi-tier web application using brooklyn
Once we are happy that this application works we can
then convert it into a version controlled service
blueprint and add this to our service catalog
When selected in the catalog all the user has to do is
provide the appropriate WAR file and database and
specify the target cloud and AMP will do the rest

10. Define New Blueprint
public class MyWebCluster extends AbstractApplication
implements MyWebClusterConstants {
// TODO build the application
}

11. Create App Tier
public class MyWebCluster extends AbstractApplication
implements MyWebClusterConstants {
def web = new JBoss7Server(this, war: WAR_PATH);
{
web.configure(httpPort: "8080+");
}
}

12. Add DB Tier
public class MyWebCluster extends AbstractApplication
implements MyWebClusterConstants {
def web = new JBoss7Server(this, war: WAR_PATH);
MySqlNode mysql = new MySqlNode(this, creationScriptUrl: DB_SETUP_SQL_URL);
{
web.configure(httpPort: "8080+");
}
}

13. Wire up App and DB Tiers
public class MyWebCluster extends AbstractApplication
implements MyWebClusterConstants {
def web = new JBoss7Server(this, war: WAR_PATH);
MySqlNode mysql = new MySqlNode(this, creationScriptUrl: DB_SETUP_SQL_URL);
{
web.configure(httpPort: "8080+").
configure(javaSysProp("brooklyn.example.db.url"),
valueWhenAttributeReady(mysql, MySqlNode.MYSQL_URL, this.&makeJdbcUrl));
}
}

14. Introduce Elasticity in App Tier
public class MyWebCluster extends AbstractApplication
implements MyWebClusterConstants {
def web = new ControlledDynamicWebAppCluster(this, war: WAR_PATH);
MySqlNode mysql = new MySqlNode(this, creationScriptUrl: DB_SETUP_SQL_URL);
{
web.factory.configure(httpPort: "8080+").
configure(javaSysProp("brooklyn.example.db.url"),
valueWhenAttributeReady(mysql, MySqlNode.MYSQL_URL, this.&makeJdbcUrl));
}
}

15. Manage Elasticity in App Tier
public class MyWebCluster extends AbstractApplication
implements MyWebClusterConstants {
def web = new ControlledDynamicWebAppCluster(this, war: WAR_PATH);
MySqlNode mysql = new MySqlNode(this, creationScriptUrl: DB_SETUP_SQL_URL);
{
web.factory.configure(httpPort: "8080+").
configure(javaSysProp("brooklyn.example.db.url"),
valueWhenAttributeReady(mysql, MySqlNode.MYSQL_URL, this.&makeJdbcUrl));
web.cluster.addPolicy(
new AutoscalerPolicy(DynamicWebAppCluster.AVERAGE_REQUESTS_PER_SECOND).
setSizeRange(1, 5).
setMetricRange(10, 100));
}
}
