Amazon MemoryDB for Redis (AWS)

Introducing Amazon MemoryDB for Redis – A Redis-Compatible, Durable, In-Memory Database Service | AWS News Blog

Instead of using a low-latency cache in front of a durable database, you can now simplify your architecture and use MemoryDB as a single, primary database. With MemoryDB, all your data is stored in memory, enabling low latency and high throughput data access. MemoryDB uses a distributed transactional log that stores data across multiple Availability Zones (AZs) to enable fast failover, database recovery, and node restarts with high durability.

GoLang vs node.js (4 years later)

 On Node.js, Go and concurrency

"Ryan Dahl, the creator of Node.js, said the following while he was talking about Node's concurrency model:

[...] I think Node is not the best system to build a massive server web. I would use Go for that. And honestly, that’s the reason why I left Node. It was the realization that: oh, actually, this is not the best server-side system ever." (in 2017)

Tesla “AI Day”: “Full Self-Driving” (FSD), D1 Chip, Dojo, Tesla Bot

Tesla AI Day - YouTube

Tesla's AI chip REVEALED! (Project Dojo) - YouTube

Top four highlights of Elon Musk’s Tesla AI Day | TechCrunch

unveiled Tesla’s computer chip, designed and built entirely in-house, that the company is using to run its supercomputer, Dojo. Much of Tesla’s AI architecture is dependent on Dojo, the neural network training computer that Musk says will be able to process vast amounts of camera imaging data four times faster than other computing systems. The idea is that the Dojo-trained AI software will be pushed out to Tesla customers via over-the-air updates.

“This is not intended to be just limited to Tesla cars,” said Musk. “Those of you who’ve seen the full self-driving beta can appreciate the rate at which the Tesla neural net is learning to drive. And this is a particular application of AI, but I think there’s more applications down the road that will make sense.”

The two main problems that Tesla is working on solving with its computer vision architecture are temporary occlusions (like cars at a busy intersection blocking Autopilot’s view of the road beyond) and signs or markings that appear earlier in the road

main objective of the event: 
“We basically want to encourage anyone who is interested in solving real-world AI problems at either the hardware or the software level to join Tesla, or consider joining Tesla,” said Musk.

Postman (tool, company): $5.6 B : API-first-World

 Postman’s Series D Funding and the API-First World | Postman Blog

a huge milestone for Postman today: We’ve closed a Series D investment round of $225 million that values the company at $5.6 billion.

“APIs have quickly become the fundamental building blocks of software used by developers in every industry, in every country across the globe—and Postman has firmly established itself as the preferred platform for developers,” said Insight Partners Managing Director Jeff Horing. “Postman has the opportunity to become a key pillar of how enterprises build, deliver products, and seamlessly enable partnerships across the ecosystem. Their continued, rapid expansion and strong management team point to a future for Postman with virtually unlimited possibilities.”

AWS vs Azure vs GCP: 2021 Cloud Report by Cockroach Labs, HarhiCorp

2021 Cloud Report by Cockroach Labs

Comparing AWS vs Azure vs GCP

Conclusion: 

• GCP had the best overall performance across the set of microbenchmarks and achieved the best raw throughput on the OLTP benchmark, Cockroach Labs Derivative TPC-C.
• Arguably surpassing AWS for the first time, Azure’s ultra disks stood out in the storage I/O experiment.
• Finally, AWS offered the most cost efficient machine on the OLTP benchmark, Cockroach Labs Derivative TPC-C.

The 2021 Cloud Report runs over 1,000 microbenchmark tests to evaluate CPU, network, storage, and TPC-C performance. We want to help others understand the performance and cost tradeoffs of each cloud and its machines.

• 54 machines evaluated
• 1,000+ tests run
• 4 benchmarks implemented
• 12 performance categories compared

What's inside the 2021 Cloud Report?

• CPU performance benchmarks
• Network performance benchmarks
• Storage I/O performance
• OLTP performance
• Analysis of advanced vs general purpose disks
• Insights into CPU processors

Docker containers without Kubernetes

Making a Case Against Kubernetes at Ably

"In a recent article in the Ably Engineering series, Ably's engineer Maik Zumstrull explained why real-time messaging platform Ably does not use Kubernetes.

Kubernetes is, without doubt, a very hot topic and is attracting a lot of interest from developers and companies. It aims to provide a platform to automate deployment, scaling, and operations of containers across clusters of hosts. Kubernetes has become one of the preferred solutions to manage container-based and microservice-oriented platforms.

Ably platform runs on AWS and, although all of their software is deployed in containers, it does not rely on Kubernetes or other runtime layers for their orchestration."

Microsoft Linux distribution

 Microsoft Has Now Its Own Linux Distribution Builder, CBL-Mariner

"CBL-Mariner is Microsoft's internal tool to create Linux distributions. Meant to power Microsoft's own Cloud infrastructure, CBL-Mariner distributions aim to consume limited disk and memory resources, as well as offer minimal attack surface."

CBL-Mariner is in some ways related to the Photon OS Project and to Fedora, from both of which it leverages a number of SPEC files. CBL-Mariner is mostly licensed under the MIT license, with Linux contributions licensed under GPL2 and drivers coming with their own licenses.

 Battle for the Cloud, Once Amazon vs. Microsoft, Now Has Many Fronts - WSJ

"Businesses and governments are signing up for a mix of providers, cherry-picking features and playing the vendors off against each other to keep costs down, company executives and cloud analysts say. It is opening up business opportunities for runners-up like Alphabet Inc.’s GOOG Google, Oracle Corp. ORCL and International Business Machines Corp., though Amazon and Microsoft remain dominant and still account for the lion’s share of cloud revenue.
