Co je Cloud Computing?

Cloud computing je fenoménom posledných rokov a akademická obec, taktiež ako veľkí IT hráči venujú tomuto konceptu čoraz viac pozornosti. Vy by ste mali tiež. V tomto článku sa vám budem snažiť priblížiť tento inovatívny trend.

Viete mi niekto odporucit vhodneho cloudoveho providera e-mailovych sluzieb pre malu firmu (20 zamestnancov)? Netreba tam nejake zazraky, ziadne doplnkove sluzby ako sharepoint a podobne, staci naozaj len email s kapacitou na jednu schranku aspon 1G, moznost pouzivat vlastnu existujucu domenu, a cena je tu dolezite kriterium.

Ahojte,
nema niekto skusenosti s nextcloud-om?
Konkretne, by som potreboval vyhladavanie v suboroch/pdf konkretneho textu.
Napriklad, uploadnem sken dokumentu, prejdem to ocr-kom, a nasledne viem vyhladavat v dokumente napriklad cislo spisu, alebo autor spisu. Je mi jedno, ci to bude hladat v suboroch fulltext, alebo to bude nejak tagovat. Potrebujem to stratka nejak zautomatizovat.
Dikicko!

Ak niekoho zaujíma manažovanie nifraštruktúry v OpenStack cloude, tak na FEI bude mat Deutsche Telekom dcerska spoločnosť Pan-Net pár prezentácií od ľudí z praxe.

- using OpenContrail
- blue - green zero down time deployment

Ten ich OpenStack cloud este ani teraz po x rokoch afaik nefunguje a jednotlive regiony si stavaju vlastne clustre.

Meanwhile public clouds own it. DT usiel vlak.

00000101000635400006359004912116083926060860595208606301

Tie vlastne cloudy su aj otazkou data across borders, a toho ze vacsina telekomov bola DT kupena a nie postavena. Ale snaha je migrovat do lokalnych coudov napriec europou, manazovanych centralne.

Vlak usiel oproti public (asi tak dekadu :D), v ramci rodiny uvidime.

0000010100063540000635900491211608392606086059520860630108606566

Tiez som zvedavy ako sa im bude darit. Ja som pre nich na tom cloude nieco robil a bola to katastrofa. Veci, ktore clovek v public clouds povazuje za samozrejmost tam neexistovali. Vratane takej basic network infrastructure ako DNS alebo Loadbalancing.

000001010006354000063590049121160839260608605952086063010860656608606722

ja s tymi neexistujucimi sluzbami stale robim:) tiez som sam zvedavy.
Ale treba povedat, ze public clouds je uplne iny level a aj tie najposlednejsie su roky pred telco svetom. DT sa najviac pokusi priblizit skor DigitalOcean modelu, ako AWS ci GCE.

00000101000635400006359004912116083926060860595208606301086065660860672208608126

Hello,

Snad spravna noda... Pouziva niekto z vas nejaky IaaS system ktory by ste mi mohli odporucit? Mam k dispozicii len 7 (hw celkom ok) node na ktorych by som deployol CEPH (len na rbd) a nad tym by som chcel nejake webove klikatko na provisioning a dashboard funkcionalitu.
Hypervisor klasika KVM na par nodach mi este bezi XEN (moj milovany Alpine Linux). Mno a... podotykam HA je absolutna nutnost. Ked som pozeral OpenStack, doslo mi ze to nie je na moj use case. Uz asi CEPH je na hrane... Ale zas teraz mam vsade DRBD medzi 2 nodami a pride mi to dost debilne riesenie.

V mojom test liste na tento tyzden mam akurat OpenNebula. Ma niekto dalsie suggestions? Daaakovala!

EDIT: Putol som sa este aj do personal cloudu, snad sa nenahnevate.

An $89, peer-to-peer “Brease” private file server on Kickstarter features four USB 3.0 ports, a GbE port, 256-bit AES, mobile support, and media streaming.

Dutch startup Brease is more than halfway to a $90,000 Kickstarter funding goal for the Brease private file server. Packages are available through June 16, starting at $89, or $119 for the functionally identical Black Thunder Edition, both of which ship in Feb. 2016. An internally identical anodized aluminum Onyx Edition goes for $199, but ships in Dec. 2015.

The Brease is a private cloud device, somewhat similar to the OpenProducts OPI or Sher.ly’s Raspberry Pi based Sherlybox. Unlike the Sherlybox, there’s no onboard storage, and unlike the OPI, there’s no email server feature. However, like these devices, the more affordable Brease runs Linux and promises no intervention by a cloud service — you create and control your own private cloud.

The device’s open source Linux stack is optimized to run a peer-to-peer protocol. It handles all requests, such as opening files and sharing folders, using SSH (Secure Shell). In addition, the Brease provides AES 256-bit encryption, with keys stored locally and accessible only to physically assigned devices.

The 11.1 x 6.8 x 2.6cm Brease is equipped with an unnamed, dual-core, 1.5GHz Cortex-A9 SoC with 1GB of user DDR3 RAM and 8GB of OS-dedicated DDR3 RAM. The device offers a gigabit Ethernet port for connecting to a modem or router, as well as four USB 3.0 ports that collectively support up to 8TB of storage.

The Brease supports up to 50 connected devices including Android, iOS, Windows and Mac, but there’s no desktop Linux support. The setup process for such devices involves scanning the pattern on the back of the Brease, and then assigning a hard disk drive or flash drive to be made available to the private Brease network.

Users can view, add, remove, or edit files, and start creating a file on one device while finishing on another. A variety of security settings range from read-only to full access. You can assign personal cloud storage to individual users, as well as assign groups of users.

The Brease offers an autonomous backup process that also supports backing up all data to a second Brease device. Support for up to RAID-6 and JBOD storage enable RAID drives to back up each other.

A media streaming feature supports “all major file formats,” and comes with a mobile media player app and an offline mode. Stretch goals include support for DLNA, Chromecast, and Airplay.

Further information

The Brease is available on Kickstarter through June 16, in packages starting at $89, with shipments due in Feb. 2016. The exception is the $199 Onyx Edition, which ships in Dec. 2015. More information may be found at the Brease Kickstarter page and Brease website.

Davam sem public svoj staro-novy projekt, tentokrat s nazvom CustomServer.sk

Pripravil som v tomto niekolko free veci, ktore by z casti mohli posuvat dopredu myslienku decentralizacie a posilnovania individualnej neutrality na internete, kedze mna vzdy sere, ze pri nejakej online komunikacii nemam kontrolu nad systemom, ktory na toto pouzivam.

Cielom je vediet to vykryt podla moznosti vo vlastnej rezii aj pre normalneho cloveka, ktoreho zaujmami nie je zrovna nastavovanie serverov.

- Sablona mailoveho servera je schopna individualnej funkcnosti v priebehu 10tich minut. Kazdy clovek moze mat svoj vlastny, sukromny mail server, bez toho, aby riesil nejake technicke / systemove stranky, ktore patria do pracovnej naplne ITckarov. Jedina nutnost je mat zaregistrovanu nejaku domenu.

- Sablona Jabber servera. Ekvivalent ku kedysi znamemu ICQ, pripadne aktualne znamemu Facebook chatu. Napisem spravu, stlacim enter, prijemca si precita. Ja stale nerad pisem o niektorych temach na serveroch inych ludi a vobec - kazda komunikacia by mala byt z principu naozaj sukromna a jej obsah by mal vlastnit vylucne jej autor.

Opat jedina poziadavka je mat vlastnu domenu a takuto sukromnejsiu verziu instantneho chatu si moze pomocou tejto sablony a grafickeho web rozhranie rozbehnut uplne kazdy.

Tretia zalezitost je ukladanie/upload dat. Ci uz sa jedna o male obrazky/fotky, az po vacsie subory napriklad v podobe zaloh, vzdy je podla mna fajn ukladat to na miesto, kde mame potencialne vacsiou kontrolu nad tym, co sa s tym dalej deje.

- Sablona 50 GB priestoru pre upload dat. Na server sa da hned pripojit prostrednictvom FTP a mozme si pohodlne uploadovat, zalohovat, zdielat, atd..

Vsetky prihlasovacie udaje a instrukcie prichadzaju automaticky emailom po zaregistrovani a vygenerovani instancie. Na poziadanie je mozne vygenerovat instanciu aj so sifrovanym suboroym systemom.

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

Nastartovat sa da tiez vlastny free OpenVPN server.

Ak by niekoho zaujimalo viac info, tak posta, pripadne:

web: http://customserver.sk
twitter: http://twitter.com/customserver_sk

Dik za precitanie, za zdielanie a za vyskusanie!

Tiez ma velmi potesi feedback, takze mozem pripadne nieco opravit a do buducnosti zase zlepsit.

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

P.S. [technickejsi-obkec] - V celom projekte ide vseobecne o generovanie roznych virtualnych serverov, podla konkretneho ucelu z predpripravenych sablon. Vzdy, ked si bezne clovek objedna virtualny server, dostane vacsinou cisty Linux na ktorom cely work este len treba urobit. toto tu ma za ulohu dorucit pripravene prostredie, podla cieloveho dovodu, pre ktore si chce clovek objednat virtualny server. (V pripade tejto nody to je mail server, jabber server a datove ulozisko. Do buducnosti mozu, resp. by to mali byt aj rozne programatorske prostredia.)

File-sharing website The Pirate Bay has moved its servers to the cloud to frustrate attempts to take it offline.

The site, which has been blamed for encouraging illegal file-sharing, will now operate from cloud-hosting providers around the world.

It says the move will save money and make it harder for law-enforcement agencies to shut it down.

"All attempts to attack [us] from now on is an attack on everything and nothing," it says.

In 2006, police in Sweden raided The Pirate Bay, shutting down its servers and taking the site offline.

The Pirate Bay (TPB) now says its new cloud-based servers, which use the internet for storage, do not have to be hosted with the same provider, or even on the same continent - making it impervious to attempts to close it down.

Its statement continues: "The site that you're at will still be here, for as long as we want it to. Only in a higher form of being. A reality to us. A ghost to those who wish to harm us."

A TPB representative told the TorrentFreak website: "Moving to the cloud lets TPB move from country to country, crossing borders seamlessly without downtime.

"The hosting providers have no idea that they're hosting The Pirate Bay, and even in the event they found out it would be impossible for them to gather data on the users."

TPB says it will retain control of the technology - transit routers and load balancers - which allows it to distribute file-sharing requests across multiple computers, and also hide the identity of both the cloud-provider and its users.

The statement said: "If the police decide to raid us again there are no servers to take, just a transit router.

"If they follow the trail to the next country and find the load balancer, there is just a disk-less server there. In case they find out where the cloud provider is, all they can get are encrypted disk-images."

Existuje implementácia/projekt p2p distribuovaného "cloudu"? Na štýle SETI, Bitcoin a iných distribuovaných projektov. Tzn. lokálny klient ktorý zdieľa: CPU/network/RAM/storage a vytvorí hardware abstraction layer na ktorom by mohol bežať samostaný OS. Alebo ešte lepšie nejaká virtualizačná vrstva ako VMware a pod.

Je také niečo vôbec možné? :) Hľadal som a nič podobného som nenašiel. Akurát že p2p nie je cloud. :)

000001010006354000063590049121160674754206751115

https://en.wikipedia.org/wiki/List_of_distributed_computing_projects

00000101000635400006359004912116067475420675111506752119

Ale no tak. :)

000001010006354000063590049121160674754206749538

Existuju typy cloud computingu, ktore vedia splnat tvoje predstavy. Nie vsak vsetky sluzby v cloud'e su zalozene na p2p technologii.

00000101000635400006359004912116067475420674953806750571

Môžeš uviesť nejaké príklady prosím na implementáciu HAL v p2p. Asi sa neviem správne opýtať googlu.

0000010100063540000635900491211606747542067495380675057106750817

skus sa pytat na "p2p grid computing".

000001010006354000063590049121160674754206749538067505710675081706751040

Možno píšem ako hotentót, ale to je zas mimo toho čo hľadám. Nerozumieš čo hľadám? "HAL v p2p prostredí" nie je dosť popisné a jasné?

Aby zdieľaný výkon, vytvoril logickú vrstvu pre CPU, MEM, STORAGE, NETWORK, I/O

00000101000635400006359004912116067475420674953806750571067508170675104006751235

tak sa pozri po nejakom "cluster" rieseni, ktore spaja pocitace cez siet. podla mna, keby sa pouzivali standarizovane (monogamne) virtualne pocitace cez siet, tak by z nich mohol byt kluster, ktory by snad mohol vytvorit tu tvoju vrstvu.

ps: vies, rad by som ti pomohol viac, ale ja staviam technologie inak. tazko ti vysvetlim ako, lebo vsetci poznaju len PC (asi aj ty). to na co sa ma tu pytas ohladne toho HAL, tak je mozne vytvorit nieco take; akurat neviem ako pomocou p2p (zatial).

0000010100063540000635900491211606747542067495380675057106750817067510400675123506751314

Ssi nie úplne :) S HA clustermi (enterprise class) som robil posledných 6rokov na OpenVMS
hands-on experience: ALPHA, VAX, IA64, x86, Sparc, PA-RISC

Viem dobre čo je cluster a tom tu nehovorím.

Toto je vízia decentralizovanej HAL vrstvy. Nie HA, ale p2p... Zároveň aj HA samozrejme :)

000001010006354000063590049121160674754206749538067505710675081706751040067512350675131406751394

no ja neviem. zatial nemam potuchy o tom, ake ma byt konkretne vyuzitie toho vsetkeho.

ja si myslim, ze tu viac hovoris o GRID'e, a nie o cluster rieseni.

Hlavné využitie: Decentralizovaná HAL vrstva, nezávislá od core network infraštruktúry. Hypoteticky: keď sa v jednom meste spojí dostatočný počet klientov medzi sebou (mesh network), vytvoria tak decentralizovaný virtuálny server bez centrálneho servra alebo potreby Internetu.

Zatiaľ je to len myšlienkový experiment, dík že mu venuješ pozornosť a rozvíjaš ho so mnou. :) Dúfam, že už rozumieš hlavnej pointe.

Čo vnímam ako hlavný problém na riešenie, je extrémne nízky inštrukčný cyklus kôli tomu, že v bežnom CPU je elektrický obvod priamo prítomný, čiže je rýchly a efektívny. Naproti tomu takýto "virtuálny elektrický obvod" má cyklus neporovnateľne pomalší (kôli rýchlosti siete) - ale zas jeden cyklus dokáže spracovať oveľa komplexnejšie inštrukcie (ktoré sa budú odohrávať priamo na klientskom CPU). To by vyžadovalo zrejme predikatívny algoritmus, alebo to bude pracovať v skokoch. :)

Dúfam že stíhaš, nie je to úplne jednoduché vysvetliť a abstrahovať. Ale hlavu a pätu to má. :)
