Cloud Migration: Major Challenges and Risks

More and more companies are migrating to the cloud, but not all are aware of the challenges involved. Cloud technology offers many benefits, yet it can also expose businesses to risks such as the loss of company data. How should you prepare for a cloud migration, and what should you keep in mind throughout the process?    

How to begin a cloud migration

  Cloud migration—the transfer of IT infrastructure and applications from local servers to a cloud environment—can present an organization with a variety of challenges. However, in the age of cloud culture and growing emphasis on process automation, this step may prove necessary to remain competitive in the market. Cloud migration requires following the steps defined in the implementation strategy. This reduces the risk of errors and allows the company to adapt to new conditions. First and foremost, potential threats must be analyzed and dependencies between applications identified. Performance, scalability, and security requirements must then be established, followed by the selection of an appropriate cloud platform. Cloud technologies are scalable and flexible, but to take advantage of these benefits, the applications used by the company must be properly designed and configured. Poor management of cloud resources can reduce the performance of the entire system. This often involves ensuring compatibility with the new environment, which may require updating applications or changing the network configuration.    

Risks of cloud migration

  Moving data to the cloud requires special security precautions. Above all, company materials must be protected against unauthorized access, cyberattacks, and data loss. This is particularly important in the case of ERP systems, especially when they contain information about processes used by the company. Data theft can expose a business to serious financial and reputational losses. Cloud migration involves financial expenditure, such as cloud-service fees and the costs of staff training and data transfer. Before implementation, these costs must be estimated carefully and an appropriate financial strategy developed. After the migration is complete, the organization must continue to monitor, maintain business continuity, and optimize the cloud environment, which entails ongoing operating costs. Cloud migration also requires specialist knowledge and skills both during and after implementation. Some tasks, such as cloud management or security configuration, may require qualified staff or assistance from an external company. Relevant data-protection laws and regulations must also be observed, especially when the data is sensitive or subject to legal requirements such as the GDPR.    

Managing migration complexity and integration with existing systems

  Several practices can help ensure an effective migration process. The first step should always be an analysis of the current situation. Its findings, including the opportunities and threats identified, can be used to prepare a detailed migration strategy. The strategy should define priorities and a schedule and specify the cloud model and provider. It should also include objectives and expected benefits, whose precise definition will depend on the industry and the company. Cloud migration may require cooperation among different teams within the organization. It is important that the process involve not only developers, but also employees from other departments. The perspectives of people without an IT background may prove valuable to the implementation team. Communication among team members should be regular and transparent, and the IT department should work closely with the cloud provider. Before migration, it is advisable to run tests in a controlled environment. This makes it possible to assess whether the integration between the systems used by the organization and the cloud works as expected. It also helps eliminate problems at an early stage and accelerates the migration process itself.    

Optimizing costs and forecasting the financial effects of migration

  Before starting a migration, every company should carefully analyze the costs of its existing infrastructure. These include:

• the cost of purchasing and maintaining servers,
• software licenses,
• electricity costs,
• management costs,
• IT staff salaries.

This information can be used for a comparative analysis and to establish a baseline for cloud-migration costs. It is also worth remembering that cloud-technology providers offer different pricing models, including usage charges, subscriptions, and payments based on the resources consumed. A detailed analysis of the migration objectives informs the selection of a specific payment model. A company may find that it does not need a monthly subscription because it intends to migrate only one application that occupies little disk space. In that situation, paying for the resources used will be more cost-effective. The cloud allows resources to be scaled according to workload, helping avoid excessive charges. This does not change the fact that cloud migration affects operating costs, so areas where savings can be made should be identified before it begins. This also helps forecast the financial effects of migration and facilitates the development of cost scenarios.    

Maintaining business continuity and minimizing risk during migration

  To maintain business continuity, a detailed migration plan must be prepared and followed closely. It is also worth remembering that cloud migration does not have to be a single, large undertaking. Applications or services can be moved gradually, allowing their operation in the new environment to be tested. Testing is also an opportunity to develop solutions for potential failures, enabling the system to be restored quickly if real problems occur. Data security is one of the challenges associated with cloud migration. During the process, particular attention should be paid to safeguards such as data encryption, security-event monitoring, and regular backups. It is also essential to verify that the provider holds the appropriate certifications. Cloud migration often involves changes to application architecture or network configuration, which may affect performance and create a risk of data leakage. To prevent this, every organization should develop change-management procedures and continuously monitor the operation of systems in the cloud. It is also advisable to have a contingency plan and test it regularly. The risks of cloud migration can also be minimized by selecting appropriate KPIs. Continuous measurement makes it possible to respond quickly to any deviations. It also indicates the effectiveness of the migration process itself and can be used to assess the costs incurred.
