Know anyone who needs cloud? I wrote Explain the Cloud Like I'm 10 just for them. skamille : I worry that the cloud is just moving us back to a world of proprietary software. BrentToderian : What city went from 14% of all trips by bike in 2001, to 22% by 2012, then leaped to 30% in 3 years by 2015, & 35% by 2018?

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?

In April 2017, Amazon Web Services announced that it would launch a new AWS infrastructure region Region in Sweden. Today, I'm happy to announce that the AWS Europe (Stockholm) Region, our 20th Region globally, is now generally available for use by customers. Public sector.

Today, I am very excited to announce our plans to open a new AWS Region in the Nordics! The new region will give Nordic-based businesses, government organisations, non-profits, and global companies with customers in the Nordics, the ability to leverage the AWS technology infrastructure from data centers in Sweden.

This post was originally published in July 2018 and was updated in July 2023. Now that Database-as-a-service (DBaaS) is in high demand, there are multiple questions regarding AWS services that cannot always be answered easily: When should I use Aurora and when should I use RDS MySQL ? What are the differences between Aurora and RDS?

What could be better than a book on the cloud? Explain the Cloud Like I'm 10. swardley: X : What's going to happen in cloud in 2019? 2) Cloud will decentralise in terms of provision not power i.e. Amazon will "invade" more of those holdouts with AWS Outpost. Do you like this sort of Stuff? I'd really appreciate it.

And if you know anyone looking for a simple book that uses lots of pictures and lots of examples to explain the cloud, then please recommend my new book: Explain the Cloud Like I'm 10. It would mean a great deal to me. They'll love you even more. It doesn't scale down to the point that is ridiculous and painful.

There are services at Netflix that use RDBMS kind of databases such as MySQL or PostgreSQL via AWS RDS. Passive instances across regions are also possible, though it is recommended to operate in the same region as the database host in order to keep the change capture latencies low. The destination may be a datastore or an external API.

Globally in 2018–2019, according to the IDC, 87% of all shipped mobile phones are Android devices. Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. So additionally conducting research on common devices in your target group might be a good idea.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Brotli is widely supported, and many CDNs support it ( Akamai , AWS , KeyCDN , Fastly , Cloudlare , CDN77 ) and you can enable Brotli even on CDNs that don’t support it yet (with a service worker).

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.
