On January 9, 2024, an online Intecracy Expert Webinar focused on a practical question for modern IT management: how to choose between on-premises, cloud and hybrid infrastructure. The keynote speaker was the well-known IT expert Mykhailo Vihovskyi, who addressed the architectural, financial and security criteria behind such decisions.
The event was held within Intecracy Group activities and was led by SL Global Service, an Intecracy Group member. For companies working with managed services, cloud platforms and resilient infrastructure, the topic is especially relevant because the discussion was not about following a specific vendor path, but about designing a dependable digital foundation.
Infrastructure choice starts with requirements
During the webinar, Mykhailo Vihovskyi emphasized that IT modernization should begin with the needs of the organization. On-premises environments provide physical control over equipment and data, yet they also require upfront capital investment, continuous administration, power and cooling resources, and long-term operational support.
Cloud services offer a different model: faster scaling, flexible resource consumption and a shift toward operational expenditure. At the same time, the speaker noted that moving workloads to the cloud without proper design may create unexpected costs and introduce new security concerns.
“The choice between local architecture and cloud services should never be a tribute to fashion or the result of a spontaneous decision. It requires a deep engineering and financial calculation,” noted Mykhailo Vihovskyi during his speech.
He also stressed the importance of assessing regulatory constraints, network latency requirements and the real total cost of ownership over a three-to-five-year horizon before selecting the target model.
Hybrid infrastructure as a balanced model
A significant part of the webinar was dedicated to the hybrid approach. This model allows organizations to keep the most sensitive systems inside a controlled local perimeter, while placing less critical services, development and testing environments, front-end components or variable workloads in a public cloud.
For organizations that need control, scalability and service availability at the same time, hybrid infrastructure may offer more flexibility than either a fully local environment or a complete move to cloud. However, this approach depends on secure integration between environments and a clear understanding of operational responsibility.
Cost, regulation and data protection
Mykhailo Vihovskyi separately addressed economic analysis and legal requirements for data storage. In sectors such as finance, healthcare and public administration, data localization rules may limit the use of foreign public clouds as the only infrastructure option.
In these cases, organizations need to compare private cloud, local data center, leased infrastructure and integration with global cloud platforms. Security must also be viewed through the shared responsibility model: the provider protects the cloud platform itself, while the customer remains responsible for data, access settings, configurations and usage policies.
A practical evaluation sequence for IT leaders
The webinar concluded with a basic decision-making sequence for IT managers. The first step is to audit the current environment and classify data by criticality. The next step is to calculate the total cost of ownership for each scenario, including network connectivity, software licensing, administration and team readiness.
Only after that does it make sense to design the target architecture. This approach aligns with vendor-neutral infrastructure planning: organizations define resilience, security and manageability requirements first, and then select the technologies and platforms that best support those requirements.
