Abstract: – In modern enterprise environments, ensuring high availability and service continuity has become a mission-critical requirement. Red Hat Enterprise Linux (RHEL), a cornerstone of many IT infrastructures, provides a robust platform for implementing self-healing mechanisms through lightweight and flexible automation. This review explores the concept of self-healing infrastructure with a focus on shell-based automation techniques tailored to RHEL environments. By leveraging native tools such as Bash scripting, systemd, cron jobs, inotify, and Ansible hooks, administrators can design reactive and proactive remediation systems capable of detecting, isolating, and correcting faults without human intervention. The increasing complexity of enterprise deployments, often compounded by limited operational windows and lean support teams, necessitates automation that is both scalable and transparent. Shell scripting remains a powerful ally due to its direct access to system resources, speed, and platform compatibility. Use cases examined in this review include automatic service restarts upon failure, filesystem monitoring and cleanup, dynamic network reconfiguration, and log anomaly detection all driven by lightweight shell scripts. Additionally, the paper examines how these automation techniques can integrate with broader observability frameworks such as ELK and Prometheus for telemetry-driven decision making. Scalability considerations, security constraints, execution reliability, and the evolution of event-driven remediation are discussed to position shell automation as a foundational element of resilient, self-healing systems. The study concludes by reflecting on emerging directions, such as AI-enhanced automation and Red Hat’s event-driven Ansible, and evaluates the continued relevance of shell scripting in modern DevOps and hybrid cloud architectures.

Abstract: Role-Based Access Control (RBAC) is a crucial security model used to manage user access and permissions in complex network architectures. In multi-zone Solaris networks, RBAC plays a key role in ensuring that users only have access to the resources they need based on their designated roles. Solaris zones allow for the isolation of different virtual environments on the same physical machine, providing greater security and operational flexibility. However, managing access control in such segmented environments can be challenging. This paper explores the implementation of RBAC in multi-zone Solaris networks, discussing the configuration of roles and permissions across different zones, the tools available for managing RBAC, and the challenges and benefits of applying this access control model. Best practices for creating, managing, and auditing roles within Solaris zones are also outlined, demonstrating how RBAC enhances security and operational efficiency in multi-zone infrastructures.

Abstract: In complex enterprise IT environments, the reliability of monitoring systems is paramount. As businesses increasingly rely on uninterrupted digital services, monitoring tools themselves must be resilient to failure. Traditional single-platform monitoring architectures risk becoming single points of failure, jeopardizing visibility when incidents occur. To mitigate this risk, organizations are turning to redundant monitoring strategies, deploying parallel observability platforms such as SL1 (ScienceLogic) and SolarWinds. These platforms, while functionally overlapping, offer complementary strengths in data collection, event correlation, visualization, and integration, making them well-suited for redundant and failover-ready deployments. This review explores the strategic deployment of SL1 and SolarWinds in active-active and active-passive configurations to ensure continuous visibility into infrastructure performance, network health, and application availability. By using both platforms in tandem, enterprises can cross-validate data, ensure continuity during platform-specific outages, and reinforce the reliability of alerts and notifications. Integration points such as shared collectors, APIs, and ITSM toolchains (e.g., ServiceNow, Jira) allow seamless cooperation between platforms while preserving operational efficiency. The review also covers key areas such as collector redundancy, alert de-duplication, data consistency, and cross-platform correlation, especially in environments supporting heterogeneous systems like UNIX, Windows, and hybrid cloud workloads. Real-world case studies from healthcare, government, and financial sectors are examined to demonstrate the impact of redundant monitoring in mission-critical infrastructures. Furthermore, the article outlines integration with external observability platforms such as Prometheus and ELK, discusses scalability and fault isolation, and assesses future trends in AIOps-enhanced monitoring. Ultimately, this review positions SL1 and SolarWinds not as competing solutions but as complementary components in a modern, resilient, and intelligent monitoring architecture.
