 Hi, I'm Jack, and I work at Indeed, and I'm going to share some insights about the open source job market. At Indeed, our mission is to help people get jobs, and we do this at scale around the world with over 200 million unique visitors every month, and job seekers who come to Indeed have access every month to about 20 million jobs, and operating at this scale allows us to explore our data and surface insights about the employment market. Today I'm going to share a few insights about how open source technologies are showing up as skills in job postings and resumes, and I'm going to focus in on a few categories. Infrastructure, public cloud, databases, and programming languages. This is a shorter version of a more in-depth talk we did last month. We believe that these kinds of insights can be really valuable for companies who are deciding what technologies to go with, for people who are considering what should I be learning to provide more value to potential future employers. In other words, these insights might help you or somebody you know get a job. If you're into live tweeting slides, we're at Indeed Eng. So let's dive right in with the infrastructure group. We looked at a few technologies that we consider open source infrastructure, and we looked at how they showed up in job postings and resumes, and Kubernetes is the fastest growing technology in this group that we looked at. Just looking at January of this year versus June, we saw twice as many job postings that mention Kubernetes. And here's a visualization of how the jobs are distributed in this group. We included Docker in this group, and it shows up in June with more than 80% of the jobs. Kubernetes at 40%, OpenStack at about 15%, and Mesos just under 10%. Moving on to the public cloud group, where we looked at Amazon Web Services, Microsoft Azure, and Google Cloud Platform. AWS is the most commonly listed public cloud provider for both candidates and jobs in this group. And here's data going back to the beginning of 2016. So here we have data points for each of these from January of 2016, January of 2017, and January and June of this year. We can see AWS hovering around 80% share of these jobs, but we see growth in both Microsoft Azure and in Google Cloud. In fact, comparing the beginning of 2016 to June of this year, there are 4.5 times as many jobs that list Google Cloud as a skill. But when it comes to applications, when it comes to application volume, there are 11 times more jobs that are getting applications that list AWS than list Google Cloud. In the databases category, we looked at popular open source databases. And MySQL is the most commonly listed open source database, again for both candidates and jobs. But it's also the most in decline. Here we look at those same four data points again for each of these database technologies, and you can see the decline for MySQL. Also, you can see that Postgres and Elasticsearch are on the increase. Finally, programming languages. What's going on with programming languages? Well, Java is the most commonly listed programming language and job postings. But Python is growing really fast, is the fastest growing programming language that we see in postings. And here's that visualization again. We see Java up around 45% in June of these jobs. But JavaScript and Python are duking it out for second place. We'd love to hear from you whether or not you find these kinds of insights interesting. If you're interested in more, please let us know. Tell us what you'd like to know. Give us feedback on this. We're going to decide on investment based on the response we get from the community. So tweet at us, add IndeedEng, hashtag OSS, job data. I'd like to give a special thanks to an Indeed product scientist named Rachel Araujo, who produced this research and gave the more in-depth talk last month at OSCON. If you want to keep track of what Indeed is up to in engineering, we have a blog at Indeed.tech and we're hiring Indeed.jobs. Thanks.
