Cloud computing?

In simple terms, cloud computing allows you to rent instead of buy your IT. Rather than investing heavily in databases, software, and equipment, companies are opting to access their compute power via the internet and pay for it as they use it.

Scalable. Flexible. Intelligent. Discover the power of cloud computing.

Cloud computing basics

When a company chooses to “move to the cloud,” it means that its IT infrastructure is stored offsite, at a data center that is maintained by the cloud computing provider (such as Oracle). An industry-leading cloud provider has the responsibility for managing the customer’s IT infrastructure, integrating applications, and developing new capabilities and functionality to keep pace with market demands.

For customers, cloud computing offers more agility, scale, and flexibility. Instead spending money and resources on legacy IT systems, customers are able to focus on more strategic tasks. Without making a large upfront investment, companies can quickly access the computing resources they need—and only pay for what they need.

Types of cloud computing

There are three different types of clouds: public, private, and hybrid. All of them vary in terms of the amount of management that is required from the customer as well as the level of security provided.

Public cloud

In a public cloud, the whole computing infrastructure is located on the premises of the cloud provider, who delivers these services to the customer over the internet. The customer does not have to maintain their own IT and can quickly add more users or computing power as needed. The cloud provider has multiple tenants sharing its IT infrastructure.

Private cloud

A private cloud is used exclusively by one organization. It could be hosted at the organization’s location or at the cloud provider’s data center. A private cloud provides the highest level of security and control.

Hybrid cloud

As the name suggests, a hybrid cloud is a combination of both public and private clouds. Generally, the customer will host their business-critical applications on their own servers for more security and control, while their secondary applications will be stored at the cloud provider’s location.


The main difference between hybrid cloud and multicloud is the use of multiple cloud computing and storage devices in a single architecture. Focusing on adding some keywords in the body.

Cloud computing services

There are three main types of cloud services: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). There’s no one-size-fits-all approach to cloud, it’s more about finding the right solution that supports your business requirements.

SaaS and its benefits

Software as a service (SaaS) is a software delivery model in which the cloud provider hosts the customer’s applications at their location. The customer accesses their applications over the internet. Rather than paying for and maintaining their own computing infrastructure, the customer takes advantage of subscription to the service on a pay-as-you-go basis.

Many businesses are finding SaaS to be the ideal solution because it enables them to get up and running quickly with the most innovative technology available. Automatic updates reduce the burden on in-house resources. Customers can scale services to support fluctuating workloads, adding more services or features they grow. A modern cloud suite provides complete software for every business need such as customer experience, ERP procurement, ERP project portfolio management, supply chain, and enterprise planning.


PaaS and its benefits

Platform as a service (PaaS) enables customers the advantage to access the developer tools they need to build and manage mobile and web applications without investing in—or maintaining—the underlying infrastructure. The provider hosts the infrastructure and middleware components and the customer accesses those services via a web browser.

To aid productivity, Oracle’s PaaS offers PaaS solutions need to have ready-to-use programming components that allow developers to build new capabilities into their applications, including innovative technologies such as artificial intelligence (AI), chatbots, blockchain, and the Internet of Things (IoT). It also include solutions for analysts, end users, and professional IT administrators, including big data analytics, content management, database management, systems management, and security.


IaaS and its benefits

Infrastructure as a Service (IaaS) enables customers to access infrastructure services on an on-demand basis through the internet. The key advantage is that the cloud provider hosts the infrastructure components that provide compute, storage, and network capacity so that their subscribers can run their workloads in the cloud. The cloud subscriber is usually responsible for installing, configuring, securing, and maintaining any software on the cloud-based infrastructure, such as database, middleware, and application software.

Cloud computing benefits

There are several trends pushing business—across all industries—toward the cloud. For most organizations, the current way of doing business might not deliver the agility to grow or provide the platform or flexibility to compete. The explosion of data created by an increasing number of digital businesses is pushing the cost and complexity of data center storage to new levels—demanding new skills and analytics tools from IT.

Modern cloud solutions help companies meet the challenges of the digital age. Instead of managing their IT, organizations have the ability to respond quickly to a more fast-paced and complex business landscape.

How cloud computing fosters innovation

Cloud customers automatically have the latest innovations and emerging technologies built into their IT systems. The cloud provider takes on the work of developing new capabilities and features. Cloud customers gain that strategic advantage.

It’s about the speed of innovation. Our Cloud customers are able to leverage a modern cloud computing architecture to innovate faster, increase productivity, and lower costs. Through an integrated cloud (SaaS, PaaS, and IaaS) architecture, we are able to provide businesses the ability to move from operations to innovation. Enterprises can deliver new apps and services, including the use of innovative technologies such as artificial intelligence (AI), chatbots, blockchain, and the Internet of Things (IoT). Companies can harness the abundance of data to gain predictive insights into their businesses and ultimately drive better outcomes for their customers.

Cloud security builds trust

Moving to the cloud removes the headaches and costs of maintaining IT security. An experienced cloud provider continually invests in the latest security technology—not only to respond to potential threats, but also to enable customers to better meet their regulatory requirements.

Oracle continually invests in every layer of cloud security as part of its overall design across global data center regions. Our trusted and proven cloud is designed to be secure at every layer of the stack. This multilayer secure cloud approach goes beyond every other cloud provider to offer security at the level the customer’s business requires.

Cloud solutions—Connect business processes

For organizations that struggle with disconnected business processes and data silos, the cloud offers a way to transform their business operations. With the cloud, there’s no need reinvent the process wheel. Complete cloud applications suites are modular, yet connected to eliminate data silos and enable a connected, intelligent business.

Oracle provides all three layers of the cloud—connected in unprecedented ways. It’s a complete, integrated platform with intelligent solutions at every layer. Organizations can now easily migrate their on-premises applications to the cloud infrastructure. Or with our complete business applications suite, including an industry-leading ERP solution, we can enable organizations to run their entire business in the cloud.

Migrate to the cloud—Start your journey to the cloud

Many organizations today are still in dilemma whether to go or no go with migrating their business’s on-premises workloads to the cloud. For most organizations, the promise of trouble-free, cloud-based information systems remains an elusive goal. Although cloud technology is pervasive, today’s installations primarily consist of new applications in private clouds managed by in-house IT staff. The vast majority of enterprise applications and infrastructure still remains on-premises. But that has been changing fast.

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.

Safe and productive journey to the cloud

Through our Industry-leading cloud computing platform, Oracle can help you easily migrate to the cloud while reducing the costs of IT modernization. Businesses can preserve their 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 comes from eliminating capital expenses by lifting and shifting entire workloads to the cloud and retiring data center assets.
