Platform engineering is a rapidly growing discipline that enhances developer productivity by providing a frictionless, self-service experience within increasingly complex multicloud environments. As organizations face the challenges of scalability and automation, platform engineers design and implement internal platforms that offer tools, services, and infrastructure for building, testing, and deploying software applications. These platforms streamline software delivery by addressing common developer issues, reducing operational complexity, and enhancing security, while maintaining compliance and consistency across development processes. Internal Developer Platforms (IDPs) are central to platform engineering, enabling developers to efficiently deliver software at scale with automated workflows, standardized practices, and baked-in security measures. While platform engineering supports DevOps by offering centralized tools and workflows, it requires collaboration across development, security, and operations teams to be effective. As the practice evolves, platform engineers will focus on creating infrastructure-as-a-product tailored to meet specific development team needs, ultimately simplifying the DevOps process and fostering greater developer satisfaction.
