The ELK Stack is a great open-source stack for log aggregation and analytics. It stands for Elasticsearch (a NoSQL database and search server), Logstash (a log shipping and parsing service), and Kibana (a web interface that connects users with the Elasticsearch database and enables visualization and search options for system operation users). With a large open-source community, ELK has become quite popular, and it is a pleasure to work with.

When managing cloud-native applications, it’s essential to have end-to-end visibility into what’s happening at any given time. This is especially true because of the distributed and dynamic nature of cloud-native apps, which are often deployed using ephemeral technologies like containers and serverless functions.

Containers have rapidly become a necessary part of the modern data center. Containers can be built on any of a number of operating system foundations — so how do you choose one over another?

At the end of Part 1, the end result was a set of polygons that represented each Cassandra node in a Kubernetes statefulset. The cAdvisor-based metrics CPU/Memory/Disk utilization are scraped by Prometheus. This second tutorial will focus on a rollup of multiple Cassandra clusters running inside Kubernetes. We will end up with three dashboards tied together to provide an overview of our Cassandra clusters.

When your end users are in peril, you – the Citrix admin, engineer, architect, consultant – need to become a superhero and save them: Diagnose the cause of issues they are facing and triage them to ensure seamless and uninterrupted connectivity.

AWS introduced Lambda Layers at re:invent 2018 as a way to share code and data between functions within and across different accounts. It’s a useful tool and something many AWS customers have been asking for. However, since we already have numerous ways of sharing code, including package managers such as NPM, when should we use Layers instead? In this post, we will look at how Lambda Layers works, the problem it solves and the new challenges it introduces.

Keep Your Apps Stable Using PagerDuty’s Integration With Google Firebase Crashlytics. Are you a developer tasked with keeping a mobile application stable and performing as expected? If so, you probably know that the worst tends to happen when you aren’t around to deal with it—like that time a high-impact crash happened when you were traipsing through Europe.

IT service alerting (ITSA) tools are quickly becoming must-haves. These tools notify IT teams about infrastructure problems, poor performance and other IT management issues. In doing so, ITSA tools empower businesses to avoid outages, reduce downtime and comply with service-level agreements (SLAs).
