This is the first war in a modern world where we have more than just one physical frontier. As Ukrainian IT community we started another one - virtual. I’ll explain you how it works here in #Ukraine and abroad
#Ukraine has more than 160K IT specialists: hardware engineers, cloud engineers, software engineers, devops, architects, QA, etc.
We do have IT security folks known as Ukrainian Cyber Alliance (@UCA_ruhate_). They were the first ones who attacked #Russia’s IT infrastructure.
Not all IT folks can stand against #Russia with fire arms. That’s the truth. But all of us want to help our army to fight against our common enemy in the most effective way. That’s the reason why we grouped into “IT army of Ukraine”.
IT army is a 100% open organization, anyone can join. So, the size of it is around 302K IT specialists from around the world - just image it! Everyone wants to fight against #Russia for a free world!
So, what it does? The organization has a schedule and shifts. 5 times a day a group of people starts a massive attacks against banks, railway companies, financial systems, marketplaces. Primary target for now is a system that replaces MasterCard and VISA. #Ukraine️
What we already see is that russian servers attempting to hide behind geotagging firewall. But it doesn’t really help, because Ukrainian IT army has backdoors to Russian networks because not all Russians are happy about this war and Putin specifically.
Another good thing is that #CloudFlare no longer allowed to be used in #Russia. At the same time there is no a drop-in replacement for it meaning the whole infra is vulnerable.
What tools does the IT army uses? From what I’ve seen people use #DRipper #slowloris #hackingtools. Most unexpected tool that I’ve seen personally is # #Java #jmeter as a stand-alone and a cloud version.
Obviously, if #Russia will enable this version of Chinese firewall there would be no way to attack. But at the same time, the consequences of absence of world-wide services like #YouTube will turn the whole young society against Putin.
I asked myself if we are in an “Internet War One” what the victory will look like? How do we know if we won? I feel like the answer is pretty obvious - nobody will die. #Ukraine #InternetWarOne

Yesterday I explained you how a war in Ukraine will affect Europe in terms of food.

Today I will explain you how it will affect your comfort [thread]:
I’d you didn’t know - Ukraine average per hour rate is pretty low comparing to European. That’s why we do lots of outsourcing businesses. We have thousands of smart engineers who do work for US/EU businesses.
VM, Mercedes-Daimler, BMW uses Ukraine as an R&D centers.

The reason why I love and hate #Kubernetes is it actually good platform to host scalable apps. But the road from developing the app to making it scalable is so painful. Here are few-reasons-why-thread:
#Kubernetes in its bare configuration can only host containers and let you talk to them. Include config maps, volumes, RBAC, etc.
If you ever wanted to scale your app on #Kubernetes you probably heard of MetricsServer - it can collect standard metrics like CPU and RAM of every pod/container.

It’s not a part of #k8s distribution - you need to install it separately.
