We carefully select and use PaaS and managed cloud services to construct our infrastructure with. This allows us to maximize our focus on what our customers are paying for: creating software for them which will typically be in use for 5+ years. We spend close to zero time on infrastructure maintenance and management, we pay others to do this for us, cheaper and more reliable. Having to swap out one service for another hasn't given us any trouble or unreasonable costs yet in the past 5 years. Unlike the article is trying to convince us of, it has massively reduced complexity for us.
