Multicloud: flexibility, security and IT cost reduction
Adopting a multi-cloud strategy means distributing applications and data across several providers to benefit from their respective strengths. Microsoft Azure, AWS, Google Cloud, as well as European players such as OVHcloud and Scaleway, all offer differentiating services: artificial intelligence, data analytics, storage, network performance and data sovereignty. IT Systèmes supports companies in the design, deployment and governance of multi-cloud architectures to reduce dependency risks, optimize costs and guarantee the continuity of critical services.

Our expertise in Multicloud
Multi-cloud architecture design
Analysis of business requirements and selection of the most suitable clouds (public, private or sovereign). We design an architecture where each workload is placed on the provider offering the best cost/performance/security ratio, to obtain an agile and resilient system.
Interconnection and network management
Setting up highly secure links between environments: VPN, ExpressRoute, Direct Connect or Peering. The aim is to ensure reliable, fast and secure exchanges between applications hosted on different clouds, while minimizing latency.
Centralized orchestration and automation
Deployment of orchestration tools (Kubernetes, Terraform, FlexFlow) to automate management and deployment. This provides a unified view of all multi-cloud environments, and facilitates the operation of complex infrastructures.
Safety and compliance across the board
Implementation of homogeneous security policies across all providers: unified identity management (IAM, tenant federation), flow encryption and alignment with RGPD, ISO 27001 and NIS2 standards. Multicloud thus remains secure and compliant with regulatory requirements.

FAQ
What's the difference between multicloud and hybrid cloud?
A hybrid cloud combines an on-premise environment with a public cloud, while a multicloud combines several public providers (Azure, AWS, Google Cloud, OVHcloud, Scaleway). Multicloud makes it possible to exploit the specific strengths of each player, while reducing dependence on a single supplier. Hybrid is a frequent step towards multicloud, but remains focused on integrating in-house infrastructures with a single Cloud partner.
What are the concrete benefits of multicloud for businesses?
Multicloud brings greater resilience in the event of supplier failure, better cost optimization thanks to the choice of the most competitive service, and the possibility of accessing differentiated services (advanced AI at Google, Office 365/Azure integration, AWS global network, sovereign cloud with OVHcloud). This approach also makes it possible to meet data localization requirements according to country or regulated sector.
Isn't multi-cloud too complex to manage?
Indeed, managing multiple Cloud providers without governance can be complex and error-prone. However, IT Systèmes simplifies management with orchestration tools, tenant federation and centralized supervision. This ensures that administration remains fluid and homogeneous despite the diversity of environments, while guaranteeing security and consistency.
How do you optimize costs in a multi-cloud environment?
Optimization requires the implementation of an appropriate FinOps strategy. This includes monitoring consumption by project, arbitrating between suppliers to choose the most competitive service, rightsizing resources and using reservations. IT Systèmes sets up budget dashboards and alerts to avoid overruns and ensure the profitability of multi-cloud choices.
Can we gradually switch to multi-cloud?
Yes, the transition to multi-cloud is generally gradual. A company can start with one main provider, then add a second for specific workloads (backup, AI, storage) and then extend the strategy. IT Systèmes accompanies this evolution in stages to limit risks and secure migrations, while building appropriate governance from the outset.
Which clouds do you recommend, depending on your needs?
The choice depends on your priorities: Azure for integration with the Microsoft ecosystem, AWS for its global coverage and wealth of services, Google Cloud for AI and Big Data, OVHcloud or Scaleway for sovereignty and European compliance. IT Systèmes does not favor a single player, but builds a multi-cloud strategy tailored to your business, regulatory and budgetary challenges.
