Note: This is a guest post by Jochen Kressin, the CTO of floragunn GmbH, the makers of Search Guard, an open-source X-Pack Security alternative. Elasticsearch is a great piece of software. We really love it. However, there is one major drawback: Elasticsearch does not have any security capabilities built in. Anyone who has access to your network can see, modify and delete any data. Which leaves your cluster wide open for malicious hackers, as the Elasticsearch ransomware attacks earlier this year have clearly shown. Welcome to Search Guard – the security suite for Elasticsearch and the entire ELK stack. When it comes to security for Elasticsearch, Search Guard is your Swiss army knife to implement security solutions tailored to your needs and your infrastructure. Regardless of whether you just want to encrypt data in transit, authenticate users against Active Director... (more)

Docker Orchestrations Compared | @DevOpsSummit #DevOps #Docker #AI #DX

Docker Orchestrations Compared By Stefan Thies Containerized software is riding a wave of growth, according to latest RightScale survey.  At Sematext we see this growth trend via our Docker monitoring adoption and via Sematext Docker Agent popularity on Docker Hub, where it crossed 1M+ pulls line. This rapid rise of containers now makes Docker the top DevOps tool among those included in RightScale survey. Overall Docker adoption surged to 35 percent, while Kubernetes adoption doubled, going from 7% in 2016 to 14% percent. Although Docker helps with DevOps automation around deve... (more)

Top @Docker Metrics | @DevOpsSummit #DevOps #APM #ML #Monitoring

Container Monitoring: Top Docker Metrics to Watch By Stefan Thies Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resources of one or more unde... (more)

Kafka Poll: Producer and Consumer Client By @Sematext | @DevOpsSummit [#DevOps]

Kafka has become the de-facto standard for handling real-time streams in high-volume, data-intensive applications, and there are certainly a lot of those out there.  We thought it would be valuable to conduct a quick poll to find out which which implementation of Kafka Producers and Consumers people use – specifically, which programming languages do you use to produce and consume Kafka messages? Please tweet this poll and help us spread the word, so we can get a good, statistically significant results.  We’ll publish the results here and via @sematext (follow us!) in a week. NO... (more)
