Are you looking to migrate your business from on-premises to Azure and take advantage of the many operational benefits, including scalability, flexibility, productivity and security? The experts at Cased Dimensions can help support your transition into the Cloud.
Read on to understand how we can help you make Cloud migration simple and painless with our free Infrastructure and Data assessment. With our support, embracing Azure has never been easier.
Cloud rationalisation
Cloud rationalisation is the act of evaluating your technical assets to decide the most appropriate way to migrate or modernise them in a Cloud environment. If you are looking to move to Azure, rationalising your on-premises workloads will ensure that you select the most appropriate migration strategy.
Choosing an Azure migration strategy
At Cased Dimensions, we can guide you through the process of Cloud rationalisation and the following migration. Microsoft have outlined 5 key migration strategies – or the 5 ‘Rs’ of rationalisation – that will support your move to the Cloud. As your trusted partner, we can help you to assess your workloads and select the option that aligns best with your overall Cloud adoption plan and ultimate business goals.
The 5 ‘Rs’ of rationalisation
Rehost
Rehosting allows you to move your on-premises software to the Azure Cloud without any changes or alterations to your existing applications. Unsurprisingly, rehosting is also referred to as a ‘lift and shift’ migration as it does just that – your applications are lifted from on-premises data centres and moved directly into your new Cloud environment. This migration strategy is ideal for new Azure users thanks to its speed and simplicity; your applications will soon be up and running in the Cloud with minimal disruption.
✅ Low risk
✅ Minimal disruption/downtime
✅ Easy and efficient
✅ Ideal for new Cloud users
✅ Less flexible migration strategy
✅ Will not improve application performance
Refactor
Refactoring is the process of making minimal changes to an application so that it can connect to Azure’s Platform as a Service (PaaS) and take advantage of the Cloud services and offerings. This strategy only requires minor changes to your application code, making it suitable for the migration of sensitive information.
✅ Long-term cost savings
✅ Faster, shorter updates
✅ Leverage Azure to improve your overall infrastructure
✅ Primarily beneficial for simple applications due to minimal code changes
Rearchitect
Some of your aging applications will be fundamentally incompatible with a Cloud environment, due to the architectural decisions made when they were originally built. You may also have applications that are compatible with the Cloud but are not Cloud-native, meaning they might be hindering your cost-efficiency and operational effectiveness. Both types of applications will require complex changes before they can be migrated to the Azure Cloud. Rearchitecting can help you to break down large applications and scale each separate part, making them more suitable for a Cloud environment.
✅ Improved application scalability and agility
✅ Easier adoption of Cloud capabilities
✅ Increased resilience
✅ Requires careful planning and implementation
Rebuild
Occasionally, an application will not warrant the business investment required to make it Cloud-compatible. Therefore, it is more sensible to take the application apart and rebuild it from scratch using a Cloud-native approach. You can do this by creating a new code base which aligns perfectly with Azure. While this might seem drastic, for a business who envisions their future in the Cloud it might be the most appropriate solution.
✅ Accelerates innovation
✅ Extremely cost-efficient in the long run
✅ Harnesses the full potential of Azure
✅ Requires careful planning
✅ May have initial upfront costs
Replace
Sometimes it is unnecessary to shift an existing workload to the Cloud. Instead, it can be replaced by a hosted application: a Software as a Service (SaaS) solution that allows you to execute and operate a software application entirely from the Cloud. If you choose this strategy, you can exclude the selected workloads from the migration process entirely.
✅ Adopts a business-process-driven approach
✅ Invests in applications that offer competitive advantages
✅ Retirement of on-premises applications
