What are the Reactors?
Reactors are community spaces where technology professionals meet, learn, and connect—to both their local peers
as well as industry-leading ideas and technology from Microsoft, partners, and the open source community.
With a diverse mix of hands-on workshops, expert panels, and community events, there’s something for everyone—
whether you’re just getting started or working on complex projects.
Reactor programming is always free and inclusive of a broad set of products, tools, and technologies.
You will find:
• First party content designed to help developers learn new skills in high-demand fields such as Machine Learning,
AI, and Data Science
• New content around breakthrough technologies and concepts such as quantum computing and blockchain
• Resources, talks and classes from Microsoft for Startups to deliver what startups need to succeed
• Cloud Advocates who deep-dive into their technical specialties and the Industry Experiences team to provide
tailored content around applications for Manufacturing, Healthcare, Retail, and other verticals
• Reactors always welcome community groups, Meetups, partners and MVPs to use our space
