In today’s corporate landscape, 90% of companies have embraced cloud technology, they have a choice of adopting public, private, or hybrid cloud solutions, or a combination thereof. Meanwhile, the remaining 10% have yet to embark on their cloud journey.
Among the 90% of cloud users, a significant portion, specifically 48%, are actively planning to migrate 50% or more of their existing applications to cloud-based environments. Additionally, 20% of these companies have even more ambitious plans, aiming to migrate their entire application portfolio to the cloud. This strategic shift underscores the growing trend toward leveraging cloud technologies to optimise operations and enhance overall business agility

In ever-evolving tech landscape, businesses must make strategic decisions about their cloud infrastructure. Hybrid Cloud solutions have gained significant traction, with 81% of IT leaders opting for this approach. However, the challenge remains: how do you pick the right cloud platform for your organisation? In this blog post, we delve into the key questions surrounding public, private, and hybrid clouds, helping you make an informed decision.

Public vs. Private Cloud: The NIST Definitions

To differentiate between public and private cloud choices, we turn to the National Institute of Standards and Technology (NIST) definitions:
Public Cloud: This cloud infrastructure is available for public use, owned and managed by various entities, and typically resides on the cloud provider’s premises. Notable examples include Oracle Cloud Infrastructure (OCI), Microsoft Azure, AWS, and Google Cloud.
Private Cloud: Private clouds are exclusively dedicated to a single organisation, accommodating multiple consumers, such as business units. They can be owned, managed, or operated by the organisation, a third party, or a combination of both, and may exist on or off-premises.
While public clouds like OCI are well-known, private clouds offer an alternative worth considering when migrating on-premises applications.

Public Cloud vs. Private Cloud: Commercial Considerations

In the context of Oracle, licensing plays a pivotal role. Ensuring you have the correct number of Oracle licenses is crucial to avoid significant costs. Licensing models vary among different cloud platforms:
On-premises and Oracle Cloud Infrastructure: 2 Intel cores = 1 CPU of Oracle license.
AWS/Azure: 2 Intel cores = 2 CPU of Oracle license.

Workload Considerations: Public vs. Private Cloud

Selecting the right cloud for specific workloads is essential:
DevOps and Active Projects: Public clouds excel when agility and scalability are paramount. They allow you to adapt quickly to changing needs without long-term commitments.
Fixed Environments: Applications like Hyperion or Oracle E-Business Suite, which have stable usage patterns, are well-suited to private cloud solutions. Here, you can tailor the infrastructure precisely to your requirements.
In the evolving cloud landscape, a hybrid approach is becoming increasingly common. It involves leveraging both public and private clouds to meet various needs, such as using a public cloud for development and testing while relying on a private cloud for production environments.

Key Considerations for Oracle Cloud Migration

Historically, Oracle workloads often took a back seat in IT roadmaps due to their complexity and integration with critical business systems. However, the cloud offers an opportunity to modernise and optimise these workloads. Migrating Oracle applications to the cloud can be challenging without the right guidance.
