While my move is among the first from the Linux cloud teams, Netflix has had staff in Australia for years (for content, marketing, and the FreeBSD OCA). Back in 2015 we'd have BPF (iovisor) meetups in Santa Clara and most contributors would be there in person, with some having travelled. You can work on Linux anywhere.

Observability platforms are becoming essential as the complexity of cloud-native architectures increases. But by 2015, it was more common to split up monolithic applications into distributed systems. For observability that scales with cloud-native technologies, organizations need an AI-driven observability platform like Dynatrace.

As the number of websites has increased with time, so has the source of traffic leading to that website. In 2015, 35% of the internet traffic came from mobile devices, 6 years later, the number is 54.8%. It can be done via open source or via commercial tools. Then, the best way is to opt for a cloud-based device lab.
