Web service technology moves significantly faster than traditional installed software packaging. It seems like web services change at the speed of sound.
Amazon has a certification program for their Amazon Web Services (AWS).
For someone transitioning to web services, a certification program may
be a great way to provide structured learning toward the exam
objectives. Amazon's test charges are currently $150 and $300 depending on the certification level.
Any certification program which requires attendance of paid course preparation, either in-person or on-line, will generally be expensive. The training industry is thriving. Online training company Udemy has a couple free AWS courses for beginners.
For someone who wants to be exposed to a broad view of a technology, and for validating current skills, these types of certifications can be useful. Potential applicants should be aware of the quick progression of web service technology which may cause a credential to rapidly become outdated.
