Swiftly to the Cloud: Rehosting reduces migration time
Rehosting (Lift and Shift): The quick move to the cloud
Rehosting, also known as "Lift and Shift", is a cloud migration strategy where applications and data are transferred to the cloud infrastructure without modification. It's the fastest and simplest way to migrate to the cloud, as no or minimal changes to the existing infrastructure are necessary. This strategy is particularly suitable for companies with tight schedules or limited resources. At GoMovin, we support you in the seamless implementation of your rehosting strategy.
Definition and functioning of Rehosting
Rehosting involves transferring an application to a public cloud without major adjustments. This is often done using tools like the AWS Server Migration Service. The advantage of this method lies in its speed and simplicity. It's like simply moving your existing IT infrastructure to the cloud without carrying out major renovation work. However, after migration, it is important to optimise the applications to fully harness the potential of the cloud. As described by optimal-systems.de, Lift-and-Shift (Rehosting) enables rapid cloud migration by transferring applications without modification.
Advantages of Rehosting
One of the main advantages of rehosting is the rapid migration. Companies with tight schedules or limited resources benefit from this strategy because they can quickly migrate to the cloud without making extensive changes to their existing infrastructure. This allows companies to quickly benefit from the advantages of the cloud, such as improved scalability and availability. Another advantage is the delegation of infrastructure management. The cloud provider assumes responsibility for the infrastructure, relieving the internal IT department. As emphasised by computerwoche.de, companies can delegate infrastructure management to the cloud provider.
Disadvantages of Rehosting
Although rehosting offers many advantages, there are also some disadvantages to consider. One of the biggest drawbacks is that the benefits of the cloud are not fully utilised. Since the applications are transferred to the cloud unchanged, monolithic architectures remain. This means that the scalability and elasticity of the cloud cannot be optimally utilised. Moreover, rehosting can lead to cost inefficiency if the applications are not optimised for the cloud. Without optimisation, the expected cost savings may not be realised. Long term, rehosting is often not the most cost-effective solution. It is important to note that rehosting is often only a first step and a more comprehensive cloud migration may be required in the long term.
Cloud-Native through Refactoring: More Performance and Innovation
Refactoring: The comprehensive transformation for cloud-native applications
Refactoring is a more comprehensive cloud migration strategy, where the codebase of applications is adjusted to fully utilize cloud features. This often involves breaking applications into microservices to enhance scalability and resilience. While refactoring is more labor-intensive than rehosting, it offers significant long-term benefits. We at GoMovin support you in planning and implementing your refactoring strategy.
Definition and functioning of refactoring
During refactoring, applications are restructured to optimally adapt them to the cloud environment. This means that applications are divided into smaller, independent units known as microservices. These microservices can be scaled and updated independently, increasing the flexibility and agility of the company. Refactoring requires a deep understanding of cloud architecture and existing applications. It is a complex process that demands careful planning and execution. T-Systems explains that replatforming and refactoring are more expensive than rehosting, but offer more benefits in the long term.
Benefits of refactoring
Refactoring offers numerous advantages, including the optimal use of cloud benefits. By adapting applications to cloud architecture, companies can fully exploit the scalability, elasticity, and performance of the cloud. This results in an improved user experience and higher efficiency. Another advantage is future-proofing and innovation. Refactoring enables companies to adapt to modern cloud architectures and develop new features and services. This is particularly important in a rapidly changing market environment. Refactoring is an investment in the future of your company.
Drawbacks of refactoring
Although refactoring offers many benefits, there are also some drawbacks to consider. One of the biggest disadvantages is the high time and resource expenditure. Refactoring requires extensive testing and adjustments, which can be time-consuming and costly. Moreover, refactoring demands specialized knowledge and expertise. It is crucial to have an experienced team of cloud experts to successfully execute the refactoring process. Another disadvantage is the increased risk due to architectural changes. Refactoring can lead to stability issues during the transition. Therefore, careful planning and execution are essential.
Rehosting vs. Refactoring: Long-term benefits decide
Rehosting vs. Refactoring: A Direct Comparison
The decision between Rehosting and Refactoring depends on your company's specific requirements and goals. Rehosting is a quick and easy solution for companies with tight schedules or limited resources. Refactoring is a more comprehensive solution for businesses that want to benefit from the cloud in the long term. It is important to carefully weigh the advantages and disadvantages of both strategies to make the optimal choice. We at GoMovin support you in decision-making and help you choose the right strategy for your company.
Speed vs. Long-term Advantages
Rehosting is the right choice when there are urgent migration requirements, such as expiring data centre contracts. It is also suitable for simple applications without high performance requirements. Refactoring is the right choice for critical applications with high performance and scalability requirements. It is also the right choice for companies wishing to benefit from the cloud in the long term. bechtle.com emphasises that choosing between Rehosting and Refactoring requires sound knowledge of the IT infrastructure, application design, and business development.
Cost Consideration
Rehosting is often cheaper in the short term but can become more expensive in the long term. This is because the benefits of the cloud are not fully utilised, and the applications may not be optimised for the cloud. Refactoring requires higher initial investments but offers cost savings in the long term. This is because the applications are optimised for the cloud and the cloud benefits are fully realised. It is important to carefully compare the short-term and long-term costs of both strategies to choose the most cost-efficient solution.
Risk Assessment
Rehosting carries fewer risks as no major changes to the applications are made. Refactoring carries higher risks as it can lead to stability issues during the transition. It is important to carefully assess the risks of both strategies and take appropriate risk mitigation measures. Careful planning and execution are crucial to minimising the risks of Refactoring. We help you understand the risks and take the right measures to ensure your cloud migration is successful.
Replatforming & Co.: Additional Migration Strategies in Focus
Summary of Other Cloud Migration Strategies
Besides rehosting and refactoring, there are additional cloud migration strategies that might be suitable for your company. These include replatforming (Lift and Optimize), repurchasing, retain, and retire. Each of these strategies has its specific advantages and disadvantages and is suitable for different use cases. It is important to be aware of the various options to determine the optimal migration strategy for your business. At GoMovin, we are happy to advise you on selecting the right strategy.
Replatforming (Lift and Optimize)
Replatforming involves adapting application modules to utilize cloud features. It is suitable for modular systems and newer applications. Replatforming offers better use of cloud benefits than rehosting but is less demanding than refactoring. It is a good compromise between speed and long-term benefits. computerwoche.de describes replatforming as a strategy where specific application modules are modified to take advantage of cloud functions for scaling and efficiency.
Repurchasing
Repurchasing involves replacing existing applications with SaaS solutions. It is suitable when a complete redevelopment is too expensive. However, repurchasing may require user adaptation. It is important to carefully weigh the pros and cons of SaaS solutions before deciding on this strategy. computerwoche.de mentions repurchasing as a specialized form of replatforming, where industry-specific software with APIs for custom microservices is used.
Retire and Retain
Retire involves decommissioning applications that are no longer needed. Retain involves keeping applications in your own data center. Retire is a good way to save costs and simplify the IT infrastructure. Retain is necessary when applications cannot be migrated to the cloud for regulatory or technical reasons. It is important to carefully weigh the pros and cons of both strategies before making a decision.
