Applications such as SAP (Systems Application and Products in Data Processing) CRM (Customer Relationship Management) and ERP (Enterprise Resource Planning) are typically run on virtual machines that are prone to temporary freezing during their operations which affects total performance. Disk corruption high I/O load memory issues and network throughput can be the causes of such disruptions. To overcome this Ratnangi Nirek a top professional in her field with broadexperience and expertise in Linux and HA Pacemaker Cluster Systems investigated the kernel modules to identify and rectify the bugs. Having extensive experience in Linux OS and High Availability (HA) Pacemaker Cluster systems she has significantly contributed in managing kernel-based systems’ stability and performance. This hashelped to mitigate critical challenges for major corporations. The resolution of these virtual machine freezes has had a profound impact on organizations. “By backporting necessary patches and collaborating with vendors I helped major corporations mitigate downtime resulting in significant cost savings from avoided prolonged system outages” she added. System reliability is enhanced by short turnaround times for intricate issues and teamwork is enhanced by efficient problem-solving procedures that require interaction with internal staff vendors and clients. This has led to improved customer satisfaction rates for the organization as a result of efficient communication and problem-solving strategies. Furthermore future occurrences have been addressed through backporting fixes to older kernels in Linux OS resulting in successful patch management. Ratnangi also solved complex virtual machine problems through her collaborative efforts for large-scale key companies involved in consumer goods footwear and financial services that are managing High Availability IT operations ensuring operational continuity and cost efficiency. As a Subject Matter Expert (SME) for Linux and HA Pacemaker Cluster systems she has partnered with prominent brands to troubleshoot complex challenges and worked closely with leading Linux distribution companies to address bug fixes and updates. Such efforts have led to substantial cost savings by mitigating downtime reducing issue resolution times and improving overall system reliability. Ratnangi has also addressed issues related to patching hypervisor on older kernels. Since patches were not available she engaged Linux vendors and internal teams to back port patches to make it stable for production. For instance a major problem with the ASR module led to a kernel deadlock that she resolved with Linux vendors to ensure stability for financial systems. The professional also dealt with a system panic problem that was due to an unpatched kernel engaging both internal and vendor teams to provide the appropriate solution. These initiatives have resulted in significant reductions in unplanned downtime and high customer satisfaction rates. She has also contributed to the academic field with her work “Understanding the Behaviour of SAP Workloads from Linux Kernel Parameters Perspective” and “Network Performance Monitoring Tools in Linux for Cloud Environments” published in esteemed industry journals. Ratnangi Nirek emphasizes the need for agile solutions in cloud environments highlighting the importance of proactive patch management and early vendor engagement to minimize downtime. Anticipating a shift toward AI-driven tools that can predict system failures the industry experts believe that continuous collaboration among internal teams and external vendors will be essential for navigating the evolving landscape of cloud-native technologies. In conclusion these projects demonstrate the importance of timely and effective collaboration in resolving critical system issues. By backporting kernel patches addressing kernel deadlocks and fixing network file system panics organizations can ensure the stability and reliability of their infrastructure. These efforts are crucial for maintaining uninterrupted operations particularly in environments where system performance and uptime are essential for business success.
