Deciding which R is right for you
Next comes the Mobilize phase, where the outcome is a complete plan for the move to AWS, including how to build the fundamental landing zone for migration. This involves establishing priorities for each of your on-premises applications based on which of the 10 so-called Rs applies best.
Is the application a candidate for simple rehosting – a lift and shift where it’s migrated directly to the cloud with minor changes? Or is replatforming a better option, either a replatform (auto) that’s an automated migration or a replatform with some code changes to adjust applications for cloud infrastructure? Other Rs that might apply include rethink, refactor (migration with significant changes), relicense, rebuild, repurchase, retain or retire.
Choosing the right R is critical for a successful migration. For example, a lift and shift doesn’t necessarily bring all the values of cloud – and can end up being more expensive, depending on what your initial infrastructure looks like. And while the first three Rs – rehost, replatform (auto) and replatform – are relatively simple to complete quickly, the next four require more effort. SoftwareOne can evaluate your application landscape and carefully consider all 10 Rs to bring applications to the best target model aligned to your needs.
In the Mobilize phase too, AWS offers help with funding, covering up to 50% of the costs involved, either as an immediate discount or as a credit on future AWS consumption.
Depending on the size of the workloads you end up migrating, you might also qualify for further AWS consumption discounts of 15% (MAP Lite) or 25% (MAP Large). After migration, you can expect to see significant efficiency improvements in infrastructure management by adding more and more automation, which will also help to reduce your costs going forward.
