Any migration ought to have clear technical and/or enterprise drivers that may be articulated in a enterprise case. At this stage, make an early name on the way you wish to migrate and in what order.
Mobilize: You would not construct a home on prime of weak foundations, so do not migrate workloads with out configuring AWS correctly. Make sure you’re organising a powerful Touchdown Zone that adheres to the AWS Effectively-Architected Framework.

2. Assign a migration sample to every workload early
AWS defines a set of migration patterns generally known as the 7Rs. This set of patterns covers the total spectrum, all the way in which from retiring workloads to utterly re-architecting them to make the most of all that AWS has to supply. A full checklist of the 7Rs could be discovered beneath.
Retire
Retain
Rehost

Working workloads on AWS carry with it a number of modifications to think about in your operational posture. Amongst them, it is best to prioritize these highest:
Cloud monetary administration: AWS brings with it a really totally different value mannequin — there’s a sudden shift from capital expenditure (CapEx) to working bills (OpEx). On-premises, it’s usually simple to attribute capital prices — you are in a position to straight hyperlink a bodily piece of infrastructure bought to the price middle that requested it. With AWS, it’s essential to contemplate how, or if, you wish to attribute prices at an elevated granularity and implement the required mechanisms to allow it.

The pillars are Operational Excellence, Safety, Value Optimization, Reliability, Efficiency Effectivity and Sustainability.
Throughout the framework exists the idea of lenses. These are workload or use-case-specific additions to the usual steering. One such lens is the migration lens. It covers the standard pillars however supplies particular migration-related steering aligned to the acquainted confirmed phases of the migration journey (uncover, assess, mobilize, migrate and modernize).
Conserving this framework and any further lenses in thoughts and evaluating in opposition to the steering all through the migration journey will enhance the prospect of profitable decision-making and subsequently a seamless migration.
5. Leverage specialist AWS companions

Service supply: These are targeted particularly on an AWS service (e.g., Amazon RDS) and are awarded when companions can exhibit that they will ship options utilizing mentioned service to a persistently excessive commonplace and in accordance with finest practices.
Effectively-Architected: The Effectively-Architected Framework that we mentioned earlier has a devoted companion program that acknowledges these companions which are notably skilled at designing for, evaluating in opposition to and remediating to get to AWS finest practices.
