The Emergence of Hybridization

Hybridization of IT infrastructures is a major challenge for businesses, whether they are small or large. This complex process involves combining on-premise and cloud services, raising numerous technical and organizational questions.​

Hybridization initially emerged out of necessity. With the rise of cloud computing, many companies found themselves with a hybrid IT infrastructure, partly on-premise and partly in the cloud, often out of necessity rather than choice. This transition was primarily driven by the need for flexibility and adaptability in the face of a constantly evolving business environment.​

Hybridization: Necessity or Choice?

One of the first steps toward hybridization was migrating email services to solutions like Exchange Online, accompanied by the introduction of services such as Azure AD. This change required smooth communication between existing on-premise systems and new cloud infrastructures. While this step, though complex, was generally well-managed, the focus now shifts to the sustainability of the hybrid solution.​

The transition also raised questions about managing applications and devices. In many cases, a complete migration to the cloud was not possible due to existing dependencies. Therefore, a hybrid approach, combining on-premise and cloud infrastructures, emerged as an interim solution. Hybridization, combining on-premise and cloud elements, poses questions about sustainability, costs, and management complexity.​

In a modern workplace context, migrating on-premise tools like SCCM to new device management solutions like Intune raises new questions for businesses. Should one move directly to full cloud? Is hybridization a good idea? How to implement hybridization? At what level? And most importantly, for how long?​

Transitioning to Full Cloud: A Target to Achieve

Furthermore, hybridization often requires a transition period during which companies must manage both old and new technologies simultaneously. This transitional period can be prolonged, especially if companies feel comfortable in this intermediate state.​

Although hybridization is a strategic choice in certain cases, the ultimate goal should be a transition to a full cloud environment. This transition requires a rigorous assessment of existing infrastructures, available skills, and application compatibility. The idea is not to see hybridization as an end in itself but rather as a step toward a more agile and cost-effective solution in the long term.​

The Importance of Assessment and Deployment Planning

Before embarking on a hybridization project, a thorough audit is essential to understand the specific needs of the company and determine the best strategy to adopt. This audit must involve not only the Chief Information Officer (CIO) and Chief Information Security Officer (CISO) but also other key departments of the company. Security is a crucial aspect of this process as the shift to the cloud involves significant changes in data and infrastructure security management.​

Training and Change Management in Cloud Transition

Transitioning to a hybrid infrastructure also involves change management within IT teams. It is crucial to train and reassure staff about new technologies and methodologies. Regular workshops and transparent communication are essential to facilitate this transition.​

Companies must invest in education and continuous training to guide their teams toward new skills and practices, especially regarding tools like Intune.​

Technical and Philosophical Challenges

With the advent of cloud technologies, a shift in IT philosophies is necessary. Traditional methods and tools designed for on-premise environments must be adapted or replaced to function effectively in a hybrid context. This evolution involves not only technology but also how IT teams collaborate and innovate.​

Defining Migration Scenarios and Use Cases

The hybrid approach must be tailored to the specific needs of each company. For example, a company operating in the energy sector with oil platforms will have different needs than a service sector company. It is essential to develop customized scenarios, taking into account the specificities of each industry and company.​

Costs of Hybridization

Financially, hybridization can be costly. Simultaneous management of on-premise and cloud infrastructures incurs additional operational costs. Therefore, it is important to conduct a detailed cost-benefit analysis before embarking on this path.​

Conclusion: Toward a Personalized and Evolving Strategy

While hybridization is a necessary step for many companies, the ultimate goal often remains a complete transition to the cloud. However, this transition must be planned and executed to minimize disruptions and maximize benefits.​

In conclusion, IT hybridization is a key step in the evolution of companies’ IT infrastructures. Although it presents challenges, it also offers opportunities for flexibility, innovation, and improved efficiency. Careful planning, appropriate change management, and constant evolution of IT approaches are essential to make the most of this transition.​
