It is crucial to prepare your tech and business specifics, needs, and ongoing goals in order to make the right decision. You can create a document with vendor selection criteria, which are vital in your case. As well, you can make a list of questions to ask vendors during your personal communication including about SLA, issue coverage, support packages, methodologies, technologies, security approaches used, and so on.
In the next phase, you can study the web and online listing platforms like ITFirms, GoodFirms, and Clutch, which include information about potential AWS consulting partners. Then, you can narrow your decision to 3-5 AWS teams by checking those firms' information only.
Lastly, you may communicate with teams about the aspects that matter to you and your business during personal contact. It is worth noting that you should pay close attention to the communication flow, level of involvement, ability to add value, and portfolio and feedback from current and former clients. By matching your points with values and expertise, you can find the AWS consulting company to suit you best.
