In the digital age, companies face increasingly complex challenges to remain competitive and respond to new market demands. In this context, cloud migration represents a strategic choice for many organizations, offering greater flexibility, scalability, and access to innovative technologies.
Before starting a migration process, however, it is important to consider several key steps:
- Resource assessment: identify the data, applications, and infrastructure to be migrated, assessing the related technical and business requirements.
- Planning: define a clear migration strategy, minimizing downtime and potential risks.
- Change management: involve stakeholders and prepare people to use the new tools and processes.
- Monitoring and optimization: continuously monitor resources, performance, and costs to keep the infrastructure efficient over time.
What to expect from a migration to Microsoft Azure?
Migrating to Microsoft Azure involves transferring and, where necessary, modernizing a company's IT resources, such as data, applications, and infrastructure, within Microsoft's cloud platform. For a company, migrating to the cloud first and foremost means evolving its IT infrastructure, laying the foundation for modernizing applications and processes.
The transition may involve initial investments and a transformation phase, but over time it can offer significant benefits in terms of flexibility, scalability, resilience, and opportunities for innovation.
Let us therefore look at the 4 main aspects to consider before embarking on a migration journey to Azure.
1. Clear SLAs and availability
One of the main objectives of cloud adoption is to ensure high availability of services and applications. Customers and employees expect to be able to access business platforms and tools at any time, from different locations and devices.
Microsoft Azure provides Service Level Agreements (SLAs) specific to different services and configurations, allowing companies to design infrastructures with defined availability levels.
The cloud also makes it possible to create redundant and resilient architectures, helping to reduce the risks associated with the unavailability of individual infrastructure components.
This makes it possible to address topics such as business continuity, backup, and disaster recovery in a more structured way, which are increasingly important for organizations that depend heavily on their IT systems.
2. Scalability
Scalability is one of the greatest advantages of cloud adoption. If a company grows or has to deal with fluctuations in demand, its IT infrastructure must be able to adapt without compromising performance and availability.
In a cloud environment, resources can be increased or reduced according to requirements, avoiding the need to size the entire infrastructure based on expected maximum peaks.
Use case
Consider, for example, a manufacturing company that needs to manage a constantly increasing flow of orders. A traditional IT infrastructure may not be able to scale quickly enough to meet growing demand, causing slowdowns, bottlenecks, and operational difficulties.
The challenge
To support growth, the company therefore decides to migrate part of its infrastructure to Microsoft Azure. The ability to scale resources becomes an important factor in adapting the IT environment to the organization's needs.
The solution
Azure services make it possible to use vertical and horizontal scalability models, increasing or reducing available resources according to requirements.
This approach can offer several benefits:
- Improved scalability: the infrastructure can adapt more quickly to changes in demand.
- Cost optimization: resources can be sized according to actual requirements, reducing the risk of maintaining unused capacity.
- Greater agility: new services and applications can be deployed more quickly.
- Better performance: a more flexible infrastructure can help ensure better performance even during periods of higher usage.
3. Application evolution
Business needs change rapidly, and applications must evolve along with them.
Microsoft Azure provides a comprehensive cloud environment that makes it possible not only to migrate existing applications, but also to modernize them and develop new ones using more modern technologies and architectures.
Depending on requirements, approaches based on containers, microservices, and cloud-native services can be adopted, making application development and deployment more flexible.
Azure also provides tools to automate parts of the development, testing, and release process, allowing companies to manage the application lifecycle more efficiently.
Cloud migration therefore becomes an opportunity not only to transfer existing infrastructure, but also to rethink and modernize the application ecosystem.
This allows companies to adapt more quickly to new market requirements and also creates a technological foundation suitable for introducing new services related, for example, to data, automation, and artificial intelligence.
4. Transparency
Where does my data go?
Today, data represents one of the most important assets for companies. Its collection, storage, protection, and use are therefore central aspects in defining a cloud strategy.
For Swiss organizations, Microsoft Azure has two regions within the country: German-speaking Switzerland, in the Zurich area, and French-speaking Switzerland, in the Geneva area. The availability of individual services may vary between regions.
This makes it possible to design architectures while also taking into account requirements related to data localization, latency, resilience, and business continuity. However, choosing a Swiss region does not automatically mean that all data and all related processing remain exclusively in Switzerland: this depends on the services used, the configuration adopted, and the overall architecture.
From a data protection perspective, companies must also consider the requirements of the Federal Act on Data Protection (FADP). The Federal Data Protection and Information Commissioner highlights, when using cloud services, aspects such as the role of processors and sub-processors, data security, and any transfers of personal data to third countries.
For this reason, compliance and governance must already be assessed during the cloud solution design phase.
How sustainable is cloud adoption?
Another increasingly important topic is sustainability. Microsoft has been investing for years in efficiency and reducing the environmental impact of its infrastructure and provides tools that allow companies to analyze and optimize the use of their cloud resources.
The ability to use shared infrastructure and dynamically adapt resources to requirements can also help limit the oversizing of IT systems. In this case as well, however, sustainability depends on how the cloud environment is designed and used.
What are the costs of a cloud migration?
Azure uses consumption models that allow companies to adjust costs according to the services and resources used. Through the pay-as-you-go model, resources can be used without necessarily incurring significant upfront hardware investments, while cost management tools make it possible to monitor and analyze spending.
For predictable workloads used over the long term, Azure Reservations are also available. In the case of Reserved Virtual Machine Instances, Microsoft indicates potential savings of up to 72% compared with pay-as-you-go rates, through commitments of one or three years. Actual savings, however, vary depending on the configuration, region, and usage.
To truly take advantage of these benefits, cloud adoption must be accompanied by careful cost management and optimization.
Our approach: the Cloud Adoption Framework
To properly manage a migration journey, it is important to follow a structured methodology. The Microsoft Cloud Adoption Framework helps organizations plan, implement, and manage cloud adoption, connecting business objectives with technology decisions.
The journey begins by defining the strategy, identifying the motivations and expected outcomes of cloud adoption. A plan is then developed, assessing applications, infrastructure, required skills, and responsibilities within the organization.
The Ready phase makes it possible to prepare the cloud environment, defining key elements such as networking, identity, security, governance, and resource structure. Microsoft considers Azure Landing Zones one of the reference approaches for creating a scalable and governed foundation for the Azure environment.
This is followed by the Adopt phase, during which applications and workloads are migrated or modernized according to business requirements. Governance, security, and operational management then accompany the entire lifecycle of the cloud environment.
Microsoft emphasizes that security must be integrated throughout all phases of the cloud adoption journey and should not be considered a separate activity.
The ultimate goal is therefore not simply to complete a migration, but to create an environment that can be monitored, governed, and continuously optimized over time.
The value of a structured cloud journey
The collaboration between Var Group Suisse and Microsoft combines technological and methodological expertise to support companies throughout their Microsoft Azure adoption journey.
Var Group Suisse can support organizations throughout the different stages of the journey: from initial analysis and strategy definition to architecture design, from migration to the subsequent management and optimization of the cloud environment.
The objective is to support the customer throughout the entire transformation journey, taking into account not only technological aspects, but also security, governance, performance, and cost control.
In summary, a migration to Microsoft Azure, if properly planned and managed, can provide Swiss companies with a more flexible, scalable platform ready to support innovation and growth over time.
