Quality control in a cloudy world

Quality Control in a Cloudy World CloudStack Collaboration Conference

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!!!

Commercial

•  Cloudsoft’s Application Management Platform (AMP) … •  Supported version of the brooklyn open source project •  See http://brooklyncentral.github.com/

•  Automates Application Deployment and Con"guration •  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

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

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 "le and database and

specify the target cloud and AMP will do the rest

De"ne New Blueprint

public class MyWebCluster extends AbstractApplication implements MyWebClusterConstants { // TODO build the application}

30/11/2012 © 2012 Cloudsoft Corporation Page: 11

Create App Tier

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

30/11/2012 © 2012 Cloudsoft Corporation Page: 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+"); }}

30/11/2012 © 2012 Cloudsoft Corporation Page: 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)); }}

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)); }}

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)); }}
