Navigating the Transition: Moving from Data Centers to the Cloud

Navigating the Transition: Moving from Data Centers to the Cloud


In today’s fast-paced digital landscape, organizations are increasingly recognizing the benefits of migrating their operations from traditional data centers to cloud-based infrastructure. This strategic shift offers greater flexibility, cost-effectiveness, and scalability, allowing businesses to adapt and innovate at a pace previously unattainable. However, the process of migrating from on-premises data centres to the cloud can be complex, expensive, and challenging, which often requires careful planning and execution.

In this blog post, we will discuss an effective approach to Data Center Exit Programs, emphasizing a time-bound strategy that classifies applications, assesses options, and leverages cloud migration funds.

As data centres have annual contracts and apps running on VMs require periodic VM upgrades to account for security and compliance packs, we recommend planning migration by backing out from the time for the next renewable cycle.

Step 1: Application Classification

The first step in any Data Center Exit Program is to classify your applications.

Expert’s Rapid Advice: A Brief Yet Valuable Tip:
We recommend beginning by creating a funnel of applications and classifying them based on their complexity and tier.

Applications can be broadly categorized as follows:

  • Commercial Off-The-Shelf (COTS) Applications: These are third-party applications that are purchased and used as-is. They may have specific licensing and support requirements.
  • Homegrown Applications: Custom-built applications that have been developed in-house. These often require more tailored migration strategies.
    • Old Stack Applications: Legacy applications that may be running on outdated technology stacks. These may require substantial modernization efforts.
    • New Stack Applications: Modern applications built on the latest technologies. These are typically easier to migrate and may involve less complexity.

Incorporating application classification into your strategy facilitates a thorough gap analysis between your current infrastructure requirements and the capabilities offered by the cloud. This in-depth gap analysis allows for a granular examination of the specific components that may require upgrades or adjustments, ensuring a comprehensive and informed transition plan.

Step 2: Assessment

Once you have classified your applications, the next step is to assess your options for each category:

  • Rehost: Rehosting involves moving applications and data from your existing data center to a new hosting environment without making significant changes to the application’s architecture. This is often the quickest and least disruptive option.  However, it’s important to note that while rehosting may streamline the migration process, certain upgrades may still be necessary, particularly for older stack applications that may not seamlessly run on modern cloud infrastructure. These upgrades ensure compatibility and performance optimization in the new environment.

  • Refactor/Replatform: For applications that cannot be easily rehosted, consider refactoring or replatforming. This involves making modifications to the application to make it more compatible with the new hosting environment. This can improve efficiency and reduce long-term costs.

Use automation to rapidly spin up environments.

  • Modernize: For old stack applications, modernization is often necessary. This may involve rewriting parts of the application, containerization, or migrating to a cloud-native architecture. While this is a more significant investment, it can lead to substantial cost savings and improved agility. Modernization could be a longer process based on the tech stack and what the business intends to do with the app.

After the migration and modernization processes are finished, we advise overseeing, administering, and consistently enhancing the transformed workloads.

Step 3: Execution

Once you’ve assessed your options for each application category, it’s time to execute your exit plan. This may involve a phased approach, where you start with low-risk applications and progressively move to more complex ones. Consider partnering with a cloud partner who has a dedicated team with expertise in cloud migration, infrastructure, and application development to oversee the process.

Smart Funding Initiatives

Data Center Exit Programs can be capital-intensive, and upfront capital expenditure (CapEx) can be a significant hurdle. Here are some smart ways to fund these initiatives:

  1. Operational Savings: As you migrate applications, especially in the rehosting phase, you can start realizing operational savings by decommissioning old hardware and reducing energy and maintenance costs.
  2. Financing Options: Explore financing options like lease-back arrangements or infrastructure-as-a-service (IaaS) models, which can help spread the cost over time.
  3. Cloud Credits: Cloud providers often offer credits to help offset migration costs. Negotiate with your chosen provider to take advantage of these incentives.
  4. Optimization: Continuously optimize your cloud resources to ensure you are getting the most value for your investment.


In conclusion, the journey from data centers to the cloud is a significant transition that can lead to transformative benefits for businesses and organizations. However, it’s important to approach this transition strategically. Careful planning, a clear understanding of your organization’s needs, and the right partners can make this journey smoother and more rewarding.

To achieve a smooth migration of your data centre to the cloud, it’s essential to have a proficient transformation team in place. This team will be responsible for promptly identifying and resolving the typical challenges associated with a complex application environment. While your internal experts have a deep understanding of your core business and the current operations within the data center, Sincera specializes in efficiently navigating the process of migrating the data centre to the cloud.
