Audit your existing technology
The first step of your cloud migration should be a pre-migration analysis. This will ensure you can develop a cloud migration strategy that considers the impact across your organisation and helps to determine the use case the cloud will serve. You should assess your physical server hardware, network infrastructure, applications and data that you use, to understand whether your current technology is compatible with a cloud migration.
Is a full cloud migration feasible?
Following a pre-migration audit, you should have an understanding of whether your current technology is compatible with a cloud migration and should have identified any tools you’ll need during the migration. In some situations, a full cloud migration may not be appropriate or feasible - you may have legacy applications that are not suitable for cloud storage, or you may work with large files that are not cost-effective (or efficient) to be stored in the cloud.
Cloud service deployment models
There are three main deployment options for hosting your data and services in the cloud. You can use public clouds such as a Microsoft Azure and Amazon AWS, private clouds where your services run in your own secure data centre, or a hybrid cloud which is a mixture of both.
Perform a cost-benefit analysis
A cost-benefit analysis should consider the migrations costs and expected new operational costs alongside future benefits and reduced capital expenditure. The efficiency savings and improvements across your organisation should also be considered. Depending on the cloud migration path chosen, it can be difficult to accurately predict ongoing costs, as they are often linked to network, power, application and bandwidth usage.
Create a cloud migration roadmap
Your cloud migration roadmap will provide an overview of each facet of the migration, including technical aspects, internal procedures, policy changes and cyber security impact in relation to data security and business continuity. The interdependencies across different teams involved in the process will also need considering, along with the impact on internal teams and the wider stakeholders.
Cloud migration project planning
Following the development of a roadmap, each element of the cloud migration will be split into smaller projects. This allows technical teams and project management teams to work together to produce project plans that can be reviewed and agreed before being implemented. Each element of the migration should be reduced to small projects that can be tested in the new environment before progressing.
Cloud migration roadmap
With a cloud migration project plan in place, you’re ready to begin the migration, focusing on minimal disruption to normal operations. The timescale for implementation will depend on the complexity of your plan, chosen deployment model and the resources available.
How we can help
We work with organisations to produce strategic plans to incorporate cloud migrations. Depending on your internal team, we can provide a range of services at each level, from oversight and guidance to implement and testing phases.
