5Common Infrastructure Services Oracle CloudQuick OverviewPlatform ServicesPlatform ServicesApplication ServicesSocial ServicesCommon Infrastructure ServicesOracle is aggressively investing in the cloud business. At OpenWorld last year we announced 5 services. Today Oracle has announced many more. They will together transform the way you can build applications and also run your business.Oracle’s Cloud offering is essentially grouped into 4 categories. This session is going to focus on one component of the Platform-as-a-Service, i.e. Java Cloud Service.Common Infrastructure Services – services like storage, caching, messaging that support services layered on top.Platform Services - Oracle offers a complete and comprehensive set cloud services that allows developers to build rich applications and business users to harness the platformApplication Services – Comprehensive range of applications and business processes, built using SOA standards – Java, SOA, BPEL, HTML5, with modern HTML5 User Interface – Web, Mobile, Outlook. Built in Business Intelligence, Social, and Mobile, Self-Service control for Business Users. Complete Data Isolation and Flexible UpgradesSocial Services – Comprehensive Social Relationship Management Platform that enable you to not only engage with prospects, customers, influencers, partners, & candidates through social media, but also listen & monitor interactions across multiple social media channels thus providing a rich experience for your customers and empowering your business to respond quickly to social chatter within your user community.

7Oracle Java Cloud Service SummaryEASY TO USE: instant access, Self-serviceCHOICE: JDeveloper, Eclipse, NetBeansSECURE: application and data isolationKey talking point on the slides itself:Java Cloud Service is basically a full, comprehensive Java EE container in the cloud.It provides easy, instant and self-service access to a complete, best-of-breed application container in the cloudNo training, learning required. Keeping user’s and customer’s productivity in mind, we have made sure that no one in your organization using Java Cloud Service has to learn any new development tools. You can continue using your favorite productivity tools to build applications targeted to Oracle Cloud.We take security seriously. The entire Oracle datacenter hosting Oracle Cloud has various levels of security, from large F5 network, firewalls, virus scanning, etc. For applications and data we believe best way to achieve security is through isolation. In Java Cloud Service, we provide a separate VM instance per service. So your application reside in truly isolated VM environment. No other tenants application can step on to your resource, or have visibility into your applications. Data isolation is provided through isolated schemas for each service. There is no co-mingling of data or applications.

9Oracle Java Cloud Service OfferingsThree pricing tiers for various usage scenarios…. All tiers have same SLAs.Simple, easy to understand pricing – no surprises, extremely easy to plan and budget. No overages, no need to constantly remind yourself to shutdown your environment to reduce bill.S2 & S4 in cluster mode for high availabilityS1 – typical usage development, functional testing as well as production for small, departmental applicationsS2 – Test 2 production environment, QA, stress testing and production for small to medium departmental applicationsS4 – Production for large applications, high availability due to 4 node clusterT: We’ve worked hard to make sure our cloud offerings are easy to use.1 Oracle WebLogic Server Managed Server instances to which the applications are deployed.2 RAM allocated to the Java heap for all of the service's Managed Servers combined to run the Oracle WebLogic Server Managed Servers and the objects consumed by your application code.3 File system space available to your service instance for the storage of your application deployment archive files as well as the servers log files.4 Maximum allowed bytes of data in and out of your service within a billing month. Database import and export are provided for free and do not deduct from this allocation.

11Oracle Java Cloud Service Application LifecycleDeveloper ServiceCommitDeployDeployJava Cloud ServiceWEBSOAPMonitor & TroubleshootRESTHow does the development lifecycle look like with Java Cloud Service?Same as your current on-premise lifecycleUse same tools, develop locally in your favorite IDEs. Deploy to your server – instead of local server, you deploy to remote server running in Oracle Cloud. All IDEs are cloud-ready – i.e. they have in-built capabilities to interact with Oracle Cloud.Manage and monitor your service and applications using either a console GUI or command line. There are Maven and Ant Task to embed the lifecycle commands right into your build process.No new technology to learn, no new skills to acquire!CLI, Maven, AntConsole

13Oracle Java Cloud Service: Integrations Developer Service – In PreviewDevelop using a turnkey development platform securely hosted in the cloudDeploy automatically to Oracle Java Cloud ServiceCollaborate using tools integrated in your IDE to manage and track tasks, builds, and documentationTight integration with Developer ServiceKey takeaway is that developers can develop applications in their IDE, checkout code from developer service, commit back changes and automatically kick off builds. At the end of the build, the application can automatically be deployed in java cloud service. A complete, comprehensive development, building and testing environment.
14Oracle Java Cloud Service: Integrations Storage Service – In PreviewOn-demand, secure, storage for your digital content in the cloudAccess content via REST or Java APIs through seamless integration with Java Cloud ServiceSimple, yet powerful administration console for management, metrics and monitoringThis service gives you the ability to store digital content in the cloud and comes with administrative controls to monitor content usage. Use it as a standalone to store your data or in conjunction with other Oracle Cloud Services. It can be seamlessly integrated into your broader development needs via REST and Java APIs.The ability to flexibly provision storage on-demand and seamlessly integrate with all of the other resources means you’ll spend less time making the nuts and bolts work together behind the scenes, and more on making magic for your end users.T: Next, let’s take a look at the Oracle Messaging Cloud Service.
15Oracle Java Cloud Service: Integrations Messaging Service – In PreviewBuild asynchronous messaging application with easeControl messaging with prioritization, selectors, persistence, transactions & guaranteed deliveryAccess via JMS APIs within Java Cloud Service or REST from outside Oracle CloudThe Messaging Cloud Service is also currently in Preview Availability. It offers asynchronous messaging, automatic prioritization, dependent selectors, persistence, and transactions, which guarantee message delivery. The service can be used from the Java Cloud Service as a JMS provider, or from outside the Oracle Cloud via a REST API and HTTP Message Push Listeners.Our messaging service bridges the gap between on-premise and cloud, making your applications extremely easy to integrate. And thanks to our embracing of open standards, your development with Oracle Messaging Cloud Service is portable making it easy to move your applications from on-premise to the cloud and back again.As the stewards of Java, Oracle is working closely with the community to ensure the move to the cloud creates an experience that is familiar to Java developers, yet fully leveraging the benefits of cloud and the integrations with our vast portfolio of technologies.T: Next, let’s take a deep dive into the capabilities of Java Cloud Service.
