Linux Foundation Will Host AsyncAPI to Support Growth and Collaboration for Industry’s Fastest-Growing API Spec

The open specification for defining asynchronous APIs gains momentum, seeks neutral home for open governance, community growth and industry adoption

SAN FRANCISCO, Calif., March 30, 2021 –  The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced it will host the AsyncAPI Initiative. AsyncAPI is a specification and a suite of open source tools that work with asynchronous APIs and event-driven architectures. It is the fastest-growing API specification according to a recent developer survey, tripling in production usage from 2019 to 2020.

Founding sponsors of the AsyncAPI Initiative include Ably Realtime, Apideck, Bump, IQVIA Technologies, Slack, Solace, and TIBCO, and AsyncAPI recently announced a partnership with Postman. Today, AsyncAPI is in production at Adidas, PayPal, Salesforce, SAP, and Slack, among other enterprise environments. 

“As the growth of AsyncAPI skyrocketed, it became clear to us that we needed to find a neutral, trusted home for its ongoing development. The Linux Foundation is without question the leader in bringing together interested communities to advance technology and accelerate adoption in an open way,” said Fran Méndez, who created AsyncAPI in 2016. “This natural next step for the project really represents the maturity and strength of AsyncAPI. We expect the open governance model architected and standardized by the Linux Foundation will ensure the initiative continues to thrive.” 

AsyncAPI helps unify documentation automation and code generation, as well as managing, testing, and monitoring asynchronous APIs. It provides language for describing the interface of event-driven systems regardless of the underlying technology and supports the full development cycle of event-driven architecture.  AsyncAPI is considered a sister project of the OpenAPI Initiative, which is focused on synchronous REST communication and is also hosted by the Linux Foundation.

“The Linux Foundation is pleased to provide a forum where individuals and organizations can come together to advance AsyncAPI and nurture collaboration in a neutral forum that can support the kind of growth this community is experiencing,” said Chris Aniszczyk, CTO and Vice President, Developer Relations at the Linux Foundation.

Supporting Quotes

Łukasz Górnicki, AsyncAPI

“AsyncAPI at Linux Foundation is another brick needed to build a solid and sustainable community for the project. We are securing a perimeter for AsyncAPI and can focus on expanding the vision of making all the specs work together for the user’s good.”

Bill Doerrfeld, NordicAPIs

“Open standards are only as strong as their community effort. The details of the AsyncAPI charter represent their ongoing community mission and goal to retain vendor neutrality around the format. AsyncAPI is taking an active role in enacting this by limiting company representation per TSC, privileging work over money, and other strategies.”

Kin Lane, Postman

“AsyncAPI joining the Linux Foundation is the final cornerstone in the foundation of the open source event-driven API specification. This creates solid groundwork for defining the next generation of API infrastructure, beginning with HTTP request and response APIs, but also event-driven approaches spanning multiple protocols and patterns including Kafka, GraphQL, MQTT, AMQP, and much more. And all of that, in turn, will provide what is needed to power documentation, mocking, testing, and other critical stops along a modern enterprise API lifecycle.”

Matt McLarty, Salesforce

“Seeing how AsyncAPI has blossomed has been incredible. Its progress has been guided by two key principles in my opinion: a focus on solving real world problems, and a focus on community. As the world of synchronous APIs and event-based communication converges, AsyncAPI plays a vital role in levelling the API playing field.”

About the Linux Foundation

Open Source Block Storage for OpenNebula Clouds

This post was contributed by LINBIT

The LINBIT OpenNebula TechDays is our mutual attempt to share our combined knowledge with the open source and storage community. We want to give you a thorough understanding of combining LINBIT’s software-defined storage solution with OpenNebula clouds.

OpenNebula is a powerful, but easy-to-use, open source platform to build and manage Enterprise Clouds. OpenNebula provides unified management of IT infrastructure and applications, avoiding vendor lock-in and reducing complexity, resource consumption, and operational costs. In contrast to OpenStack, which understands itself as a collection of independent projects, OpenNebula is an integrated solution that provides all the necessary components to manage a private, hybrid, or edge cloud.

LINBIT SDS is a software-defined storage solution for Linux that delivers highly-available, replicated block-storage volumes with exceptional performance. It matches perfectly with OpenNebula.

Both open source, both born in the Linux software ecosystem. LINBIT SDS is perfectly suited for a hyper-converged deployment with OpenNebula’s hypervisor nodes since it saves a lot on CPU and memory resources when you compare it to Ceph. At the same time, it delivers higher performance (IOPS and throughput) for single volumes and accumulated over all volumes of a cluster.

Find all webinars, case-studies, and discussions listed in the TechDays schedule. It is a free all-virtual event on April 20th and 21st, with direct access to LINBIT and OpenNebula experts.

See you there!

Celebrate 30 Years of Linux With Training & Certification Offer

On August 25, 1991, Linus Torvalds posted the now famous Usenet message announcing he was building a free operating system. In the 30 years since, that operating system – Linux – has become the most important open source software project in history, powering all supercomputers, serving as the backbone of the cloud and internet, running a majority of mobile phones and mainframe computers, and even operating on the International Space Station.

After all this time Linux is more important than ever. In fact, the 2020 Open Source Jobs Report from The Linux Foundation and edX found that Linux is the most in demand skill amongst technical hiring managers. This is largely due to rapidly growing adoption of cloud technologies which run on Linux. 

To celebrate 30 years of Linux, and to help more individuals become successful, productive members of the Linux community, Linux Foundation Training & Certification is discounting some of our most popular Linux training courses and certification exams through the end of 2021 by 30% with code LINUX30, including:

Certifications:

  • Linux Foundation Certified IT Associate (LFCA) – Demonstrates knowledge of fundamental IT concepts including operating systems, software application installation and management, hardware installation, use of the command line and basic programming, basic networking functions, security best practices, and other related topics to validate your capability and preparedness for an entry-level IT position.
  • Linux Foundation Certified System Administrator (LFCS) – Demonstrates you have the ability to design, install, configure, and manage a system installation, and understand key concepts such as networking, storage, security, maintenance, logging and monitoring, application lifecycle, troubleshooting, API object primitives and the ability to establish basic use-cases for end users. The discount is valid for the standalone exam or bundled with the associated training course.
  • Linux Foundation Certified Engineer (LFCE) – Demonstrates your ability to deploy and configure the Linux operating system at enterprise scale, and shows you possess all the necessary skills to work as a Linux engineer. The discount is valid for the standalone exam or bundled with the associated training course.

eLearning Courses:
