Editor's Notes

• #12: As we all know, Cloud enables a layer of abstraction that hides the underlying complexities of the platform from the end-user. This abstraction is delivered via a Self-Service interface. We have, over the months, seen a wide range of customers, with different usage needs of the Self-Service interface. Some data centers want to enable infrastructure provisioning via Self-service (IaaS), some want to enable Database (DbaaS) and Java Platform Provisioning (PaaS) while others want an automated way to run test Loads/regressions on an existing platform (TaaS).In Enterprise Manager 12c, we have an out-of-box Self-Service Application that lets end-users deploy a wide range of these services. End users can choose to provision Virtual Assemblies, databases or Java applications on the cloud platform using a Service Catalog. As a Self-Service user, you can not only deploy the services, but also monitor them. You can also perform tasks such as backing up the database or scaling up the Weblogic servers. Our vision of self-service to allow you to expose any of your IT services through this interface. IaaS, DBaaS, PaaS are just the starting point. Very soon you will see us introducing functionality to automate test life cycle. Using the self-service interface, you will able to push a button to provision the test application and data, run the rest, collect performance and health statics, and de-provision the environment when the testing has been completed. And finally, [touch of humor], if you do not like our Self-Service Console, you can use our APIs or put your own branding on the Console.
• #14: As we hear more and more from our customers, we figure out that some customers are Greenfield, they want to start fresh Cloud projects with brand new hardware and software and in some cases, even new data center, while some others are Brownfield, in the sense, they want to transform their existing assets into a consolidated cloud platform. It is therefore important to plan out the Cloud deployment model starting with the discovery and baselining of existing assets. Enterprise Manager 12 provides automated discovery capabilities that can find existing assets and then manage them. We have a Consolidation planner that can provide P2P, P2V, P2Exa advisories based upon both technical and functional constraints (such as production and test cannot be co-located).Then comes setting up the Cloud. This is a very, very important phase for everyone who believes that cloud is transformational, that it is not merely a web layer on top of pre-existing, complex, automation scripts. We, in Development, spent a considerable amount of time over the last couple of years in defining and architecting the resource models for the cloud-right from Storage to Applications, for both physical and virtualized infrastructure, so that as customers you can maximize the benefits of consolidation and cloud. Enterprise Manager 12c offers capabilities such as Bare Metal provisioning of Hypervisor, setting up of server and storage pools that make the life of the Cloud Administrator easier. We can zone these resources based on cost center or QOS. Enterprise Manager leverages our Virtualization Storage Connect technology, where we have worked with vendors like Netapp, Hitachi, Fujitsu, etc to drive storage automation via best-of-breed storage technologies. And finally after we have set up the Cloud infrastructure, we can enable access control, quotas, retirement policies, etc to make the service available to cloud users.
• #19: Topic Name
• #20: The deployment procedures saved and locked in the prior step, are then published to the service catalog as service templates. The self service user selects one of these service templates to as part of the database requests.
• #22: Deploying application in the cloud is a huge challenge.  Typically one either deploys various components of the application individually and then manually wires them together.  Some vendors even allow you to deploy a bunch of VMs together but you still have the hard and painful job of connecting the dots. The problem gets even worse if you start to think other deployment constraints – such as which components should be co-located and which not, what should be the network topology of the application (i.e. DB and MW should be in different network segments), which components can scale out and if so how should the scale out happen.As you know, we recently announce Oracle VM 3.0. We now have full integration with OVM 3.0 for virtualization management and cloud resource management. Oracle Virtual Assembly Builder and Oracle Enterprise Manager 12c address this challenge. Using OVAB, application developers and architects  can model the application topology graphically, define all dependencies and deployment constraints, and package the entire application in form of what we call an application assembly. These assembly can then be uploaded to the centralized software library in Enterprise Manager for self-service deployments.We (Oracle) plan to offer assemblies for all our products which will allow you to deploy any of our products – including packaged applications – by click of a button. Enterprise Manager has a live link back to Oracle which will notify you of the availability of new assemblies and download them if you are interested.
• #23: The out of box portal, that support all three models – IaaS, DBaaS, and PaaS. The database portal shows the list of requested databases, the requests and their status, notifications for databases due to expire, and resource usage against quota set for the user.
• #26: Once the Cloud is operational, it needs to be monitored and managed on a continuing basis. With Enterprise manager 12c, we provide persona-specific views for the cloud administrators and cloud consumers so that they can monitor what’s going on. The Administrators, who are responsible for the health of the Cloud can track the incoming requests and fulfillment status. They can drill down into the database, middleware, server or storage layer and detect potential bottlenecks. We also provide necessary automation out-of-the –box so that they can add more servers and storage into the cloud infrastructure.The Cloud consumer (Application owner) can monitor the overall service level and scale out resources if needed. Enterprise manager 12c lets them define policies based on either schedule or performance, and associate automated remediation actions such as scale-up or scale-down or power-off with those policies. [Provide one or two examples of schedule and performance based policies like shutdown during weekends to avoid higher metering].
• #28: While Cloud Shared Services and Self-Service application sounds exciting, they also bring some challenges. As different tenants start sharing the same piece of platform or infrastructure, there needs to be accountability on the usage, else resources will get hogged.. Also, we need to acknowledge that the ease of Self-Service Provisioning in itself may lead to over-consumption of resources resulting in sprawl. To mitigate this, organizations often meter the usage and optionally chargeback [or show back] the tenants . Though an IT organization may not actually charge back its LOBs, this provides a transparent mechanism to budget resources and optimize the cloud platform on an ongoing basis.What we have in Enterprise manager 12c is a very sophisticated and flexible Metering and Chargeback mechanism where one can define models based on Fixed cost, Configuration (such as version, licenses) or utilization or a combination of these. We provide you the ability to meters resources at various levels – host/VM level, database and middleware. [Give one or two examples]. On the reporting side of things, we have integration with LDAP so that we can traverse the organizational hierarchy and generate the consumption report at various levels-individual, department, etc. The IT metrics can then be fed into a billing tool such as Oracle’s own Billing and revenue Management solution, should any organization want to generate a bill for the tenants/consumers. Enterprise Manager also provides a rich performance management database (PMDB – AWR, JVMD Repository) which provides you historical view cloud performance. This functionality in conjunction with metering and chargeback functionality enables you to manage, monitor and optimize cloud performance, capacity and costs.
