Premeštanje podataka i aplikacija u oblake predstavlja novi izazov za korporativne SOC-ove, koji nisu uvek spremni za praćenje tuđe infrastrukture. Prema podacima Netoskopa, prosečno preduzeće (očigledno u SAD-u) koristi 1246 različitih oblačnih usluga, što je 22% više nego prošle godine. 1246 oblačnih usluga!!! Od toga se 175 odnosi na HR usluge, 170 na marketing, 110 […]
U poslednjim godinama, vesti su preplavljene izveštajima o novim distribuiranim računarstvenim mrežama koje se pojavljuju bukvalno niotkuda, a koje pokušavaju da reše razne probleme — učiniti grad pametnim, spasiti svet od kršenja autorskih prava ili obrnuto, tajno preneti informacije ili resurse, pobėći iz pod kontrolom države u određenoj oblasti. Bez obzira na oblast, svi […]
To objavo namenjam tistim ljudem, ki so lagali o certifikatih, zaradi česar skoraj nismo namestili bengalskih ognjemetov v naših dvoranah. Zgodba je starejša od štirih let, a jo objavljam zdaj, ker se je NDA iztekel. Takrat smo spoznali, da smo skoraj v celoti napolnili podatkovni center (ki ga oddajamo v najem), hkrati pa se energetska učinkovitost ni prav dosti izboljšala. Predtem smo imeli hipotezo […]

Tistega večera bodo svoje izkušnje in znanje delili: Bijan Mihail, Raiffeisen banka TRENDI IN TENDENCE V DEVOPS INDUSTRIJI DANES. Po korakih dogodka, ki je potekal junija v Londonu […]
Zelo neprijetna zgodba se je zgodila z enim mojim znancem. A kolikor je bila neprijetna za Mihaila, je bila zame prav tako zanimiva. Moram reči, da je moj prijatelj zelo dober UNIX uporabnik: zna sam namestiti sistem, namestiti mysql, php in opraviti najpreprostejše nastavitve nginx. Ima tudi deset ali dvanajst spletnih strani, posvečenih gradbenim orodjem. Ena od teh spletnih strani, posvečena motornih žag, je trdno […]
Dober dan, skupnost! Moje ime je Mihail Podivilov. Sem ustanovitelj javne organizacije „Medium“. Večkrat so me prosili, naj napišem kratko, a celovito vodilo o tem, kako se povezati v omrežje decentraliziranega internetnega ponudnika „Medium“ v načinu overlay, torej, brez neposredne povezave na usmerjevalnik ponudnika „Medium“, temveč z uporabo interneta in Yggdrasil kot prevoza. V […]
Introduction Hello, friends! I was surprised to notice that there aren't many articles on Habr dedicated to the products of a vendor such as [Extreme Networks](https://tssolution.ru/katalog/extreme). To address this and to better acquaint you with Extreme's product lineup, I plan to write a small series of articles, starting with switches for Enterprise. The series will include the following articles: Overview […]
In large cloud systems, the issue of automatic load balancing on computing resources is particularly pressing. This concern has also been addressed by Tionix (developer and operator of cloud services, part of the Rostelecom group). And, since our primary development platform is OpenStack, and we, like everyone, are lazy, it was decided to find a ready-made module to handle this […]
In the previous article, we discussed attempts to use Watcher and presented a report on the tests. Such tests are periodically conducted for balancing and other critical functions of large corporate or operator clouds. The high complexity of the task may require several articles to describe our project. Today, we publish the second article in the series, dedicated to load balancing of virtual machines in the cloud. A bit of terminology […]
Today we will study PAT (Port Address Translation), a technology for translating IP addresses using ports, and NAT (Network Address Translation), a technology for converting IP addresses of transit packets. PAT is a specific case of NAT. We will cover three topics: — private or internal (intranet, local) IP addresses and public or external IP addresses; — NAT and PAT; — setting up NAT/PAT. Let's get started […]
The standard local network in its current (average) form was finally established many years ago, and its development has since stalled. On one hand, the best is the enemy of the good; on the other, stagnation is not particularly good either. Moreover, upon closer examination, a modern office network capable of handling almost all tasks of a typical office can be built cheaper and […]
Kljub temu, da je na Habré že več člankov o IPFS, naj takoj pojasnim, da nisem strokovnjak na tem področju, ampak sem večkrat izkazal zanimanje za to tehnologijo. Vendar so moji poskusi dela z njo pogosto povzročali nekaj bolečine. Danes sem se spet lotil eksperimentiranja in dosegel nekaj rezultatov, s katerimi bi rad delil […]
