If you are a candidate looking for your next role that involves an in-depth knowledge of Elasticsearch and the wider Elastic Stack then you will want to revise beforehand. In this resource guide on the top ELK interview questions, we've listed all of the leading questions that candidates are commonly asked about Elasticsearch, Logstash & Kibana (and their contemporary tools and plugins) alongside the answers. Want to improve your knowledge further?

In the era of data abundance, there exists a significant need for database systems that can effectively manage large quantities of data. For certain types of applications, an oft-considered option is Apache Cassandra. Like any other piece of software, however, Cassandra has issues that could potentially impact performance. When this happens, it’s critical to know where to look and what to look for in the effort to quickly restore service to an acceptable level.

The use of NFV migration is becoming commonplace, it is made apparent there is a need for a higher degree of software management, smoother upgrades, and deployment process. Due to the complexity of the migration, Telcos have been deterred from adoption. A solution should be out there to aid businesses in managing and deploying network automation, orchestration, and managed services. In general, a telco network is complex and needs to be managed using multiple perspectives.

Work changed in 2020, but not just for the lockdown period—it changed forever. It’s become increasingly clear that we won’t return to the old working model. Workers have become accustomed to the autonomy of a remote environment. The 2021 Employee Experience Imperative found that six in 10 employees prefer some amount of remote work. As vaccine rollouts make office work possible again, employers are realizing hybrid is the future.

In the era of digital workplaces, AI has emerged as a catalyst in enabling simplified, intelligent, and intuitive ITSM and ITOM environments. From increasing workflow automation, reducing IT staff workload to reducing downtime and outages, AI can help accelerate your service delivery and provide meaningful business insight.

Covid fundamentally disrupted the modern workplace in a way that no technological innovation ever has. Yet despite the initial acceleration of digital transformation initiatives, we’re still burdened by the legacy of the “old way”— work about work. According to the Anatomy of Work Index, an average employee switches between 10 tools up to 25 times per day. This level of app switching makes it challenging for team members to prioritize and execute work.

In modern software systems, it is common for several developers to work on the same project simultaneously. Siloed working with infrequent merging of code in a shared repository often leads to bugs and conflicts that are difficult and time-consuming to resolve. To solve this problem, we can adopt continuous integration.

Monitoring services and applications in just a few clicks – that’s the dream of every SRE and developer, but this is very difficult because most applications don’t expose metrics in a standardized format. This article will introduce the current pros and cons of the Prometheus exporters ecosystem and how we leveraged the power of the open-source exporters in Sysdig to radically simplify the user experience to allow you to monitor your applications in just a few clicks.

Last year we cooked a holiday ham using Sysdig. Honestly, just revisiting that makes me hungry, but it got me thinking. What about dessert? Today, I’d like to discuss baking a pie and eating it with Prometheus Remote Write. But not just any pie: a Raspberry Pi. Specifically, I’d like to introduce you to Pi-hole, an open-source project that has become very popular in the community. In this article you’ll learn how easy is Monitoring Pi-hole with Prometheus Remote Write.
