  1. Infrastructure as code (IaC) is the practice of automatically managing computing platforms, such as Internet of Things (IoT) platforms. IaC has gained popularity in recent years, yielding a plethora of software artifacts, such as Ansible playbooks that are available on social coding platforms. Despite the availability of open source software (OSS) Ansible playbooks, there is a lack of empirical research on the quality of these playbooks, which can hinder the progress of IaC-related research. To that end, we conduct an empirical study with 2,952 OSS Ansible playbooks where we evaluate the quality of OSS playbooks from the perspective of executability, i.e., if publicly available OSS Ansible playbooks can be executed without failures. From our empirical study, we observe 71.5\% of the mined 2,952 Ansible playbooks cannot be executed as is because of four categories of failures.

  2. Generative artificial intelligence (AI) technologies, such as ChatGPT have shown promise in solving software engineering problems. However, these technologies have also shown to be susceptible to generating software artifacts that contain quality issues. A systematic characterization of quality issues, such as smells in ChatGPT-generated artifacts can help in providing recommendations for practitioners who use generative AI for container orchestration.We conduct an empirical study with 98 Kubernetes manifests to quantify smells in manifests generated by ChatGPT. Our empirical study shows: (i) 35.8% of the 98 Kubernetes manifests generated include at least one instance of smell; (ii) two types of objects Kubernetes namely, Deployment and Service are impacted by identified smells; and (iii) the most frequently occurring smell is unset CPU and memory requirements. Based on our findings, we recommend practitioners to apply quality assurance activities for ChatGPT-generated Kubernetes manifests prior to using these manifests for container orchestration.
