Erik Näslund shares his experience of migrating from Terraform to Pulumi, highlighting the benefits and challenges encountered during the transition. Initially content with Terraform, Erik found its reliance on the Hashicorp Configuration Language (HCL) limiting, as he preferred using familiar programming languages like Python for defining infrastructure. Pulumi's support for multiple languages such as TypeScript, Python, and Go, combined with its ability to group resources into logical components, appealed to him, allowing for greater flexibility and ease in organizing code. The migration process involved manual rewriting of Terraform code into Pulumi due to limitations of automated tools, but this allowed for better code structuring. Erik appreciated Pulumi's faster performance, robust documentation, and the convenience of its web console for infrastructure management. Despite some issues with Gitlab integration and potential concerns about Pulumi's pricing model, Erik found the transition to Pulumi enhanced his productivity and enjoyment in managing infrastructure.
