These 15 Tech Companies Chose the ELK Stack Over Proprietary Logging Software

companies that use the elk stack

As part of the widespread movement towards open source software, the ELK Stack is rapidly moving from a niche platform to the most common log management platform in the world.

A recent Black Duck Software study surveyed 1,300 individuals ranging from business analysts to CEOs to software engineers on the future of open source. Of the respondents, 78% reported that either part or all of their companies’ operations run on open-source software. In addition, 66% stated that their companies use open source in developing software for customers.

The ELK (Elasticsearch, Logstash, and Kibana) Stack is an example of the trend towards open source that has disrupted commercial proprietary markets (including, in that example, Splunk). ELK was created in 2010 and has already been adopted by well-known organizations such as LinkedIn, Netflix, and Stack Overflow. ELK supports many different log management and analysis use cases including typical IT operations, customer support, website traffic, business intelligence, security events, and user behavior.

To give you a better understanding of the widespread adoption of ELK in various industries, I have compiled the following list that shows how various companies are using ELK right now.

Netflix

The company chose Elasticsearch for its automatic sharding and replication, flexible schema, nice extension model, and ecosystem with many plugins. Netflix’s use of Elasticsearch to store, index, and search documents have grown from a couple of isolated deployments to more than fifteen clusters comprised of nearly 800 nodes that are centrally managed by a cloud database engineering team.

Stack Overflow

However, Stack Overflow uses Elasticsearch as a means to support full-text search capabilities. Furthermore, each Elasticsearch box also has 300 GBs also using SSDs, the search box is powered by a REST interface. Stack Overflow is using Elasticsearch because it performs better on SSDs and that Lucene.net could not handle the company’s workflows as a result of locking issues.

LinkedIn

The IT team integrates ELK with Kafka to support their load in real time. Their ELK operations include more than 100 clusters across more than twenty teams and six data centers.

Fujitsu (OpenStack Cloud)

Accenture

In that linked presentation, company staffer Alexander Szalonnas states that the company prefers the ELK Stack to Splunk because it is open source, has a simple web interface, and can use plugins to extend its functionality.

Tripwire

Medium

According to Medium’s engineering team, ELK is used to debug production issues. The company also uses the Elasticsearch, Logstash, and Kibana stack to detect DynamoDB hotspots.

Swat.io

According to its operations engineer, Swat uses ELK to log the AWS S3 storage that stores its sites’ traffic activity. This helps to control and forecast the growing cloud costs that are driven by new user demands.

IFTTT

The IFTTT operations team uses Elasticsearch for real-time monitoring and receiving alerts on API events. They also use Kibana to visualize worker processes and see API performance in real-time.

HipChat

hipchat logoHipChat is an Atlassian tool that is well-known for its internal and private enterprise chat services. According to High Scalability, HipChat’s chat services doubles its user base every few months. The company’s use of Elasticsearch as a search backend allows for horizontal scalability, which supports HipChat’s overall growth. HipChat states that they moved to Elasticsearch because it can process any amount of data, it is multi-tenant, and it can handle a node loss transparently with sharding and replication.

Five Additional Online Services

The 10 best-known ELK use cases above represent only a tiny few of the millions of other users that exist. For some variety in use cases, here are a few more interesting examples that we have come across in our research: Ideato, MixRadio, Vinted, Auth0, and Rancher.
