Quick Verdict
Choose Docker if you want the industry standard for containerizing applications and microservices.. Docker's biggest strengths include industry standard — every developer should know docker and eliminates 'works on my machine' problems. Choose Pulumi if you prefer infrastructure as code using real programming languages with ai assistance.. Key advantages include use real programming languages instead of dsls and ai assistant generates infrastructure from descriptions.
