photo taken by Adrian Cockcroft A year ago I did a talk at re:Invent called Architecture Trends and Topics for 2021 , so I thought it was worth seeing how they played out and updating them for the coming year. I did a few talks on this subject early in the year, and linked this to the sustainability advantages of serverless architectures.

At hardware reset the boot code is granted maximally permissive architectural capabilities.

But that’s also a problem that 5G vendors could solve; virtual LANs ( VLANs ) are hardly a new concept. That’s the real promise of 5G. Mike Loukides.

This blog post gives a glimpse of the computer systems research papers presented at the USENIX Annual Technical Conference (ATC) 2019, with an emphasis on systems that use new hardware architectures. As a consequence, the vast majority of the papers in the past has usually focused on conventional X86 or GPU-accelerated architectures.

One of the most significant announcements of the entire conference to me was that of per-function concurrency control. Correspondingly, 3GB functions should see a 2x CPU performance improvement over 1.5GB Lambdas, but this is through doubling the number of cores the function has access to, rather than double the virtualized time-slices.
