Hybrid cloud is presented as the end-to-end solution that allows addressing the challenges of speed and responsiveness on the one hand and control, security and compliance needs on the other, and is an approach that most companies envision. why ? Especially how?

Digitization and the use of the most advanced technologies are becoming crucial to the competitiveness of companies. In recent years, cloud computing has proven itself as a deployment lever on the scale of digital transformation.
However, decision makers are still not sure of adopting a true cloud hosting strategy. The frequency stems in part from a diverse presentation around three main groups of architectures: public cloud, private cloud, and hybrid cloud. Each of them has strengths and weaknesses. Choosing and setting the right cloud environment is more sensitive because implementing these new technologies is a complex and costly process. In addition, companies fear creating confusion with their internal data centers and weakening their IT security.
The resilience inherent in a hybrid cloud addresses many of these challenges. This environment brings together several cloud infrastructures—including at least one public cloud and one private cloud—that are interconnected, allowing for the portability of data and applications. A company can choose its location according to its sensitivity to risk, increased digital activity, or even a new strategic direction.
Hybrid cloud is designed to be able to express historical architectures, and provides all the benefits of cloud platforms under optimal security conditions. Even better, it facilitates the application of new technologies such as artificial intelligence.
In the digital race, the ultimate resilience of the hybrid cloud will be a major asset. It will support the emergence of a new paradigm for fully virtualized software architectures.
In this “hyperflex” environment, different data ecosystems – including applications, software, interfaces, or hardware – can interact in an automated or collaborative manner in modular and interchangeable logic.
The indisputable advantages of the hybrid cloud have convinced IT decision makers. According to one of our recent surveys of 600 of them, 90% have already used these solutions.
But companies should not underestimate the challenges of implementing hybrid cloud. This transition cannot be reduced to mere acquisition of technology aimed at modernizing networks.
To give its full measure, Hybrid cloud design should be considered as the backbone IT strategy.
Before committing, two basic questions should be asked:
– Of the many combinations of architectures that the cloud offers, which one is the most relevant to my organization?
If a hybrid cloud better suits a company’s needs, how can digital activities be segmented and distributed across different platforms?
Responding to it implies judging between the expected level of safety often dictated by the industry’s regulatory and competitive environment and efficiency requirements. Thus, a vehicle manufacturer can decide to provide the highest level of protection for its model design and put ventilation system simulation activities, which require more computer power, into the cloud.
Once these strategic decisions are made, a hybrid cloud deployment requires a rigorous roadmap, organized around a few key issues. Among them, the implementation of the implementation requires strong technical and organizational resources. To reduce the risk, a steering cell can be created. Another implication for companies is that levers to reduce costs – which can be up to 60% – or even security policy must be reconsidered in a mixed cloud environment.
Hybrid cloud adoption therefore requires increasing skills and transforming operational models. But this requirement is commensurate with the opportunities offered by this technology.
