Clients often ask me, what's the cost of our IT services? How do they map to different applications? What are the availability and performance of our services in geographically dispersed centers? How can we effectively reduce the total cost of ownership while improving service quality? A good starting point is to actively use IT-monitoring technology. It provides a quantitative starting point that-with a good understanding of IT systems and service needs-facilitates improving your IT performance. In this installment, Josune Hernantes, Gorka Gallardo, and Nicolás Serrano provide an overview of recent monitoring technologies. I look forward to hearing from both readers and prospective column authors about this column and the technologies you want to know more about. -Christof Ebert PROVISIONING NEW INFRASTRUC-TURES and applications has never been so easy. Virtualization and cloud computing have made this process routine. The result for enterprises' IT infrastructure has been an increased number of diverse elements to manage. Furthermore, nowadays systems are usually geographically dispersed or use different OSs, which complicates their management. This situation has renewed the importance of an old topic: monitoring IT infrastructures and applications. Also, as more businesses rely on software, IT system health is critical for 24/7 customer service and support. The systems can be on-premise applications, applications on a public or private cloud, or any combination of these.The rst step in this process is monitoring the IT infrastructure at the hardware, service, and application levels. Figure 1 describes the architecture.Here, we discuss current tools that monitor networks to detect issues, ensure the components' availability, and measure the resources those components use.
