The Linux Foundation's membership continues to expand. This week, three new companies joined the open source consortium, bringing strengths in software-defined networking, storage and managed hosting to the organization.

The new members—IIX, Micron Technology and Planisys—represent a diverse set of companies. The first on the list is a major provider of network interconnection and optimization services, which it delivers through a software-defined interconnection platform that runs on Linux. IIX chief technology officer Paul Gampe said his company will use its membership in the Linux Foundation "to engage and give back to the broader development community."

Micron Technology specializes in DRAM, NAND and NOR Flash storage. Linux is widely used by the company's customers, said Steve Moyer, the company's vice president of Storage Software Engineering, who added that "joining the Linux Foundation allows Micron to invest in the future of Linux and its collaborative development model, while creating exciting new opportunities for customers."

Argentina-based Planisys delivers an array of managed hosting services, including CDN, corporate email, high-redundancy DNS, email marketing and virtual private servers Hosting Control Panels. "Our specialty is high traffic and complex scenarios, mission-critical websites and systems where high availability, resiliency and nearly 100 percent uptime are needed,” said Carlos Horowicz, CEO and co-founder of Planisys. "This is a perfect environment for running Linux, which also makes it a natural fit for massively scalable distributed infrastructures."

All three companies join the Linux Foundation as silver members, the organization's third tier of membership. They bring the total membership of the consortium, which promotes the development of Linux and other open source software, to 229.
