However, IT leaders often hesitate to move critical applications into the hands of cloud service providers—partly because they don’t see a clear migration path for entrenched legacy assets, but also because they aren’t sure whether public cloud services are ready for enterprise needs. They are right to be skeptical: Most public cloud offerings are characterized by insufficient deployment choices, limited compatibility between on-premises and cloud systems, and a lack of enterprise-level management capabilities.
Oracle has a realistic view of cloud computing that encourages a hybrid cloud infrastructure, with pre-packaged applications and tools for rapid provisioning, migration, centralized management, and integration. In the remainder of this brief, you’ll learn how these tools can simplify your journey to the cloud. The Cloud That Stands Apart Oracle Cloud represents the industry’s most complete offering. It spans the infrastructure, platform, and application layers, with integrated consumption models and centralized management. This highly versatile cloud platform offers choice of deployment—private, public, and hybrid cloud options, with similar technology in each category and easy interchangeability among them. It supports many different applications, languages, operating systems, and data types. It’s ideal for both Oracle applications and third-party applications. And all apps run identically, whether deployed on premises or in the cloud.
Built around multiple levels of defence, Oracle Cloud is incredibly secure. Oracle’s extensive cloud security includes physical data centre access controls, encryption of data, and a multi-layered, “defence in depth” security strategy that encompasses all layers of the technology stack. Oracle Cloud is based on open standards, which ensures optimum flexibility as your business’ needs change over time. You can use existing skill sets and talent across all environments and technology stacks—and run both Oracle and non-Oracle workloads in the cloud. You don’t have to compromise performance for your application workload in the cloud—it is built into the Oracle Cloud infrastructure at all levels. With Oracle Bare Metal Cloud Services, your applicationworkload enjoys the predicable performance it needs with dedicated resources to avoid “noisy neighbours.” For mission-critical workloads, you can deploy Oracle Database Exadata Cloud at Customer to ensure the extreme performance your business workload requires. Oracle Cloud helps you easily migrate to the cloud while reducing the costs of IT modernization. You can preserve existing investments with familiar tools, and you don’t have to rewrite code to migrate your software assets. Elastic capacity through “cloud bursting” gives you the capacity you need without having to oversubscribe. The biggest savings come from eliminating capital expenses by lifting and shifting entire workloads to the cloud and retiring data centre assets.
While public cloud services were initially popular for development and testing (DevTest), Oracle Cloud is ready for production applications as well. Oracle’s cloud-based management tools enable you to manage your on-premises and public cloud assets from a single console, using the familiar processes and skill sets that you have today. Some organizations begin by moving their DevTest operations to the cloud. Others use the cloud to expand their analytics horizons, or to establish a cloud archive to back-up their data. After that, they gradually move key applications to the cloud to extend on-premises infrastructure with new cloud platforms.
Of course, Oracle Cloud supports much more than just Oracle applications and infrastructure. For existing customers currently running Oracle software (such as Oracle E-Business Suite; Oracle’s JD Edwards, PeopleSoft, and Siebel applications; as well as Oracle Database and Oracle WebLogic Server) on premises, these applications can simply be repackaged for a seamless deployment experience in the cloud. The truth is, you can migrate any workload to Oracle Cloud—and most customers do. The majority of application workloads that are deployed on Oracle Cloud consist of Microsoft Windows, IBM WebSphere, Tomcat, and JBoss, along with third-party databases such as SQL Server, DB2, Mongo DB, Cassandra, Postgres, and Sybase.
Oracle also offers cloning tools to seamlessly copy applications and data to the cloud. With what we call “lift and shift” migrations, you can move existing systems to the cloud intact—quickly and easily.For customers with mission-critical workloads that cannot tolerate business disruption, Oracle offers a zero-downtime migration option called Oracle Golden-Gate Cloud Service that enables you to move applications and databases to the cloud without impacting production operations.
Oracle Golden-Gate Cloud Service features a real-time data replication service so you can move data in bulk, and even transform dissimilar data types to one consistent format to simplify operations. Oracle also offers tools for lifting and shifting VMware and KVM workloads to the cloud without any changes. As a final reassurance of business continuity, you can run your on-premises and cloud apps in parallel until you are certain the migration has been completed successfully.
Oracle Cloud is ideal for data warehouse workloads. Database administrators (DBAs) have instant access to pre-integrated infrastructure such as servers, network, storage, and database platforms. This makes it easy to migrate existing on-premises data warehouses to the cloud—or create a new one altogether. You can migrate mixed workloads—such as online transaction processing (OLTP) and analytics—of any size, from small applications to enterprise information systems. Oracle Cloud supports structured and unstructured data suchas NoSQL and Hadoop. Your DBAs will enjoy cloud-based tools for monitoring, analytics, and management. They can also take advantage of a wide range of platform services for business intelligence, as well as use Oracle’s cloud-based integration services to accommodate third-party analytics. For high-performance data warehouses, consider Oracle Database Exadata Cloud Service, which includes preconfigured hardware and software to eliminate costly data warehouse builds—and offers extreme performance for instant analytics.
Some customers can’t move their data and applications to the public cloud because of data privacy concerns, industry regulations, or unique security constraints. Fortunately, they can still take advantage of the scalability, affordability, and ease of public cloud technology by using Oracle Cloud technology in their own data centre. Based on a flexible subscription model, Oracle Cloud at Customer is ideal when data must remain on premises for regulatory, privacy, legal, or performance reasons. This is another service that only Oracle offers. In other words, if you can’t move to the public cloud, Oracle will move the cloud to you by deploying and operating an instance of Oracle Cloud Machine or Oracle Database Exadata Cloud at Customer behind your firewall. You will enjoy the same robust cloud platform services, the same automatic software updates, and the samesubscription-based pricing model as all Oracle Cloud customers do. Rather than purchasing hardware and software, you can simply subscribe to it, and let Oracle handle every aspect of installation, configuration, patching, lifecycle management, upgrading, and monitoring. You get a “mini” Oracle Cloud— all fully managed—behind your firewall. Customers with existing on-premises licenses can leverage that investment to use Oracle Database Cloud at a fraction of the old PaaS price. Oracle Bring Your Own License (Oracle BYOL) allows Oracle Database customers to seamlessly migrate to the cloud. With Oracle’s 100 percent workload compatibility and license mobility, you can preserve your existing investment. In addition, running Oracle Database in Oracle Cloud is faster and much more cost effective than with Amazon AWS, delivering the industry’s lowest total cost of ownership.
Problems with Third-Party Clouds
- Insufficient deployment choices
- Cumbersome migration requirements
- Limited compatibility between on-premises and cloud environments
- Fragmented management tools
- Inconsistent performance
- Gaps in security, visibility, and control
- Lack of availability and redundancy for critical workloads
The Superiority of Oracle Cloud
- Unified management tools for monitoring applications and infrastructure
- Superior utilities for capacity planning, compliance, scheduling, and log analytics
- Compute services that are 11.5 times faster than commodity servers, yet cost about 20 percent less
- Storage capacity at about one-seventh the cost of commodity cloud alternatives
