It's really interesting to see a company report they are saving millions in storage fees alone by moving *from* AWS to on-prem, considering so many companies were influenced to move to AWS to begin with because of Netflix's articles many years ago about the money they saved on storage costs moving *to* AWS.

@varbin @f4grx @nixCraft @torproject Well, you can dynamically block them based off packet rate & amount of requests and rate-limit them as well as limit them in terms of transfer rate.

Not to mention you rarely see DDoS attacks from residential IPs and ISPs are quick to disconnect offending hosts upon reporting them, so worst-case one blocks a /24 for 24 hours.

  • This doesn't even account for the fact that #Skiddie-Tools like #LOIC are easily dstinguishable and filter for.

Again: if this is a real problem, any decent datacenter / hoster / upstream will gladly pick up the phone or reply to your support request via mail.

  • After all, they too don't like it when someone hammers their infrastructure, so they have a vested interest in #Blackholing bad traffic at the #IX level.

#DECIX even officially recommends that as a means to handle large-scale DDoS attacks and keep everyone else online.

  • To me a "#Layer7" solution like #Anubis comes way too late as it already incurs billable traffic at many hosters and datacenters and we don't want to cough up money because of someone else trying to #blackmail us (which is the #1 reason for DDoS'ers to do so!)…

The cloud landscape is evolving at record speed in 2025:

*️⃣ Multi-Cloud strategies are now the standard
To boost resilience and avoid vendor lock-in, more companies are splitting workloads across multiple cloud providers.

*️⃣ Edge computing moves mainstream
Processing data closer to its source is now essential for real-time analytics and operational efficiency.

*️⃣ Serverless architectures accelerate innovation
Serverless computing is empowering developers to focus on code, not infrastructure.

*️⃣ Green cloud and sustainable data centers
Sustainability is a top priority.

*️⃣ Zero trust security takes center stage
With cyber threats growing, businesses are moving beyond perimeter-based defenses-adopting Zero Trust models to secure every access point.

KI, Ki, Ki.

Riesige Rechenzentren.

Immer mehr, immer mehr, immer noch mehr.

Strom, Wasser, Lärm, Verschmutzung.

Es zerstört das Leben von Menschen.

Aber Hauptsache, du kannst dir ein "fany Bild" und einen "kreativen Song" kreieren lassen und ein LLM, wie zB ChatGPT fragen, wie morgen das Wetter wird.

Mei, ist das alles beknackt!

I saw an article today that was talking about some cloud #hyperscaler - Google, I think - switching to a high-voltage DC power system in anticipation of supporting #racks with a power density of 1 MW.

A #megawatt, in a standard rack? I know Nvidia's selling GPU racks at 120 kW, which is much more than a traditional rack can handle, and there's talk about 250 kW, but this is 4 times more than even that. It seems ... impractical.

Doing a few calculations - a 42U standard rack is 600mm wide, a meter deep, and 2 meters high, for a total volume of 1.2 m^3. If that was a solid block of mild steel, it would mass ~9500 kg. In round terms, 1MW input would be able to raise the temperature of that almost-ten-tonne steel block from the freezing point of water to the boiling point of water... in one second flat.

The cooling requirements for a system like this would be prolific, but I think it would require some never-seen-in-computing changes as well, like a "thermal crowbar". Just as a crowbar circuit shorts the power to cause a breaker to trip when some failure condition is detected, you would need something to immediately kill power to such a rack if the cooling system was impaired at all. You don't have time for this to take ten seconds!

They're also talking about it being an 800VDC system, so you need 1250A. For that, you would need a copper busbar with a cross-sectional area of more than 500 mm^2...

This doesn't smell right.

Soirée upgrade réseau du #datacenter de la cave...

Nos últimos anos, tem havido uma tendência à descentralização – de iniciativas em web descentralizada para infraestruturas de rede descentralizadas. Neste documento de posicionamento, apresentamos uma visão arquitetônica para a descentralização de infraestruturas de serviços em nuvem. Nossa visão é sobre infraestruturas de nuvem comunitária sobre infraestruturas de acesso descentralizadas, ou seja, redes comunitárias, utilizando recursos reunidos da comunidade. Nossa visão arquitetônica considera alguns desafios fundamentais da integração das atuais tecnologias de virtualização de ponta, como Redes Definidas por Software (SDN), em infraestruturas comunitárias que são altamente instáveis. Nosso objetivo de projeto proposto é incluir virtualização de rede e processamento leve com mecanismos de tolerância a falhas para garantir um nível de confiabilidade suficiente para suportar serviços locais.

Recent news that Amazon has pulled back on datacenter leasing deals has concerned some AI investors - especially on the backs of a similar Microsoft pause. But the company says it's nothing more than "routine capacity management." Read more at @theregister. #Amazon #Microsoft #AI #AWS #Datacenter #Tech #Technology flip.it/YBhYZ0

The Register · Relax, AWS reassessing colo lease talks is just 'routine capacity management'By Dan Robinson

#Frack to the future? #Geothermal energy pitched as #datacenter savior
An independent research body claims that geothermal power generation could provide an answer to the growing energy requirements of #datacenters.
But there's a catch. It focuses on techniques that employ hydraulic fracturing, or #fracking, to avoid being restricted to areas with naturally available geothermal energy, and depends on operators being prepared to pay a "green premium."
