I'm a cloud solutions developer.
My employer uses the Microsoft Azure stack and is a 'partner' of Microsoft which means they get an affiliation with Microsoft that they can use to promote to customers etc. Part of that partner status is about having a given number of Azure-certified people in the company, of which I am one (I'm part of a large team of developers and they have many times the amount of people needed to meet that requirement). The company's sales pitches and proposals to customers include the use of the Azure stack and the benefits of that, and state prominently that they are a Microsoft affiliate. It is sort of a 'seal of approval' that the company is legitimate and knows their way around Azure.
The company sells services to businesses, e.g. an appointments management platform. The customer would sign up with my employer and receive access to this appointments system to use in their own business (doctor appointments, car mechanic appointments, sales visits, etc). It is a commodity product that we can 'tailor' to the particular customer's requirements with some extra consultancy. Most of the customers just buy the default version, a small percentage have an additional requirement like integration with some specific in-house system they already had.
In my personal capacity, I am now wanting to get certified on Amazon Web Services (AWS) and perhaps also Google Cloud Platform (GCP) (which are the main competitors of Azure). This is for my own career development reasons, as I want to be able to have more opportunities in the future outside of being restricted to 'only' Azure experience. AWS and GCP offer similar certifications to Azure as a cloud developer. I don't know what might happen in the future with my company. I am conscious with all the talk of recession that it's not a bad idea to be a bit more "future proof". I would do the study and test outside of work time.
My LinkedIn profile states my title and employer. I am "connected" on LinkedIn with a number of my colleagues including senior managers.
Would it be considered generally acceptable to get certified in a competing technology (AWS when the company is Azure based)? Is it a conflict of interest in some way? If it's acceptable to get certified, would it look strange to post to my feed that "I just passed AWS Certified Developer" with the badge? Is that 'undermining' the company? What would that look like to a potential or current customer who looks up my employer and associated employees?
