The last two years in software development and operations have been characterized by the emerging idea of “observability”. The need for a novel concept guiding the efforts to control our systems arose from the accelerating paradigm changes driven by the need to scale and cloud native technologies. In contrast, the monitoring landscape stagnated and failed to meet the new challenges our massively more complex applications pose. Therefore, observability evolved as a mission-critical property of modern systems and still attracts much attention. The numerous debates differentiated monitoring from observability and covered its technical and cultural impact on building and operating systems. At the beginning of 2019, the community reached consensus on the characteristic of observability and elaborated its core principles. Consequently, new tools and SaaS applications appeared marking the beginning of its commercialization. This post identifies the forces driving the evolution of observability, points out trends we presently perceive and tries to predict future developments.Continue reading
End user monitoring – Establish a basis to understand, operate and improve software systems
End user monitoring is crucial for operating and managing software systems safely and effectively. Beyond operations, monitoring constitutes a basic requirement to improve services based on facts instead of instincts. Thus, monitoring plays an important role in the lifecycle of every application. But implementing an effective monitoring solution is challenging due to the incredible velocity of changes in the IT landscape and because there is no silver bullet applicable for everyone. This post outlines the basics of monitoring on a strategic level and focuses on some practical facets, so you can derive a concrete solution well adapted for your unique needs and circumstances. The first part covers monitoring principles followed by monitoring tactics for web-based applications. This post concludes by pointing out major challenges you will probably face when implementing a monitoring solution.
