Na\u0161e slu\u017eba WEDOS CD<\/a> (Cloud Disk) nar\u016fst\u00e1 na popularit\u011b. Minul\u00fd m\u011bs\u00edc jsme poko\u0159ili metu 1000 aktivn\u00edch WEDOS CD a to je slu\u017eba st\u00e1le je\u0161t\u011b v testovac\u00edm provozu a prozat\u00edm pro ni je\u0161t\u011b nem\u00e1me detailn\u00ed n\u00e1vody, jak ji vyu\u017e\u00edt.<\/p>\n

<\/p>\n

Ka\u017ed\u00fd WEDOS CD tak vyu\u017e\u00edv\u00e1 po sv\u00e9m. N\u011bkdo na z\u00e1lohov\u00e1n\u00ed, jin\u00fd k synchronizaci dokument\u016f mezi po\u010d\u00edta\u010di, pohodln\u00e9mu sd\u00edlen\u00ed velk\u00fdch soubor\u016f anebo jako online n\u00e1hradu za kancel\u00e1\u0159sk\u00fd bal\u00ed\u010dek. Ov\u0161em WEDOS CD toho um\u00ed daleko v\u00edce. Je to plnohodnotn\u00e1 online kancel\u00e1\u0159, kter\u00e1 t\u00fdmu lid\u00ed umo\u017en\u00ed posunout spole\u010dnou pr\u00e1ci k daleko vy\u0161\u0161\u00ed efektivit\u011b. V\u00edme, \u017ee funguje, proto\u017ee tak pracujeme i my.<\/p>\n

Co n\u00e1m v\u0161ak v na\u0161\u00ed online kancel\u00e1\u0159i opravdu chyb\u011blo, byla pohodln\u00e1 a jednoduch\u00e1 videokonference. Kdy\u017e m\u00e1te kolegy mezi dv\u011bma datacentry a \u010d\u00e1st t\u0159eba doma na homeoffice, tak videokonference jsou z\u00e1klad. Pot\u0159ebujte se domluvit, upravit dokumenty a hod\u00ed se i funkce sd\u00edlen\u00e9ho obrazu.<\/p>\n

Za\u010dali jsme proto vyu\u017e\u00edvat open source \u0159e\u0161en\u00ed Jitsi, kter\u00e9 spojuje v\u0161e v\u00fd\u0161e uveden\u00e9. Nen\u00ed nutn\u00e9 nic instalovat, sta\u010d\u00ed b\u011b\u017en\u00fd internetov\u00fd prohl\u00ed\u017ee\u010d (nejl\u00e9pe Chrome) a a\u017e 75 lid\u00ed se m\u016f\u017ee bavit v jedn\u00e9 m\u00edstnosti.<\/p>\n

Kdy\u017e jsme vid\u011bli, jak moc n\u00e1m Jitsi pom\u00e1h\u00e1, \u0159ekli jsme si, \u017ee to je p\u0159esn\u011b to, co WEDOS CD pot\u0159ebuje. Za\u010dali jsme tak experimentovat s t\u00edmto open source \u0159e\u0161en\u00edm na na\u0161ich serverech a p\u0159ekvapilo n\u00e1s, jak efektivn\u00ed je.<\/p>\n

Co je Jitsi<\/h3>\n

Jitsi je open source \u0159e\u0161en\u00ed pro konferen\u010dn\u00ed hovory s velmi silnou a rostouc\u00ed komunitou. V roce 2020 po\u010det u\u017eivatel\u016f p\u0159ekonal 10 milion\u016f. Je postaven\u00e9 na jednoduchosti a vysok\u00e9 bezpe\u010dnosti.<\/p>\n

K pou\u017e\u00edv\u00e1n\u00ed nic nepot\u0159ebujte. Sta\u010d\u00ed nav\u0161t\u00edvit str\u00e1nku meet.wedos.com<\/a>, zalo\u017eit si m\u00edstnost a pozvat do n\u00ed dal\u0161\u00ed \u00fa\u010dastn\u00edky. Pokud pot\u0159ebujte soukrom\u00ed, tak si u m\u00edstnosti nastav\u00edte heslo. K pohodln\u00e9 videokonferenci sta\u010d\u00ed modern\u00ed internetov\u00fd prohl\u00ed\u017ee\u010d jako je t\u0159eba Chrome anebo aplikace Jitsi do mobiln\u00edch telefon\u016f (na mobilu lze tak\u00e9 vyu\u017e\u00edt prohl\u00ed\u017ee\u010d). Stejn\u011b tak jsou i aplikace do PC, ale v PC sta\u010d\u00ed bohat\u011b prohl\u00ed\u017ee\u010d. To je v\u0161e. \u017d\u00e1dn\u00e9 instalov\u00e1n\u00ed, nutn\u00e1 registrace ani nic podobn\u00e9ho.<\/p>\n

V samotn\u00e9m rozhran\u00ed nen\u00ed pot\u0159eba pro b\u011b\u017enou komunikaci nic nastavovat. V\u0161e se optimalizuje pro ka\u017ed\u00e9ho p\u0159ipojen\u00e9ho u\u017eivatele individu\u00e1ln\u011b. Kdo chce, m\u016f\u017ee si p\u0159idat jm\u00e9no.<\/p>\n

Jitsi obsahuje i chat s mo\u017enost\u00ed pos\u00edl\u00e1n\u00ed soukrom\u00fdch zpr\u00e1v, sd\u00edlen\u00ed okna programu, monitoru anebo cel\u00e9 plochy. Jitsi m\u016f\u017eete napojit i na YouTube a vyu\u017e\u00edt ke streamov\u00e1n\u00ed t\u0159eba konference. Jitsi m\u00e1 i funkci nahr\u00e1v\u00e1n\u00ed, ale tu prozat\u00edm m\u00e1me vypnutou.<\/p>\n

Bezpe\u010dnost a spln\u011bn\u00ed GDPR na prvn\u00edm m\u00edst\u011b<\/h3>\n

Jitsi m\u00e1 jednu doslova fascinuj\u00edc\u00ed p\u0159ednost, pokud si pot\u0159ebujte promluvit ve dvou. Po nav\u00e1z\u00e1n\u00ed komunikace server – klient, p\u0159enech\u00e1 komunikaci na klient – klient (peer-to-peer (P2P)). \u0158\u00edd\u00edc\u00ed server pak u\u017e jen dohl\u00ed\u017e\u00ed, aby v\u0161e fungovalo, jak m\u00e1. Samotn\u00e1 komunikace tak v\u016fbec nejde p\u0159es server, ale pokud je to mo\u017en\u00e9, tak pouzr mezi jednotliv\u00fdmi \u00fa\u010dastn\u00edky. Jedn\u00e1 se o stav za ide\u00e1ln\u00edch podm\u00ednek, tak\u00e9 to mus\u00ed um\u011bt prohl\u00ed\u017ee\u010d (nap\u0159\u00edklad Google Chrome).<\/p>\n

D\u00edky tomu lid\u00e9, kte\u0159\u00ed jsou t\u0159eba na intranetu, mohou mezi sebou komunikovat ve vysok\u00e9m rozli\u0161en\u00ed a s lidmi mimo je komunikace v ni\u017e\u0161\u00edm rozli\u0161en\u00ed. Velmi dob\u0159e to jde i v r\u00e1mci jednoho lok\u00e1ln\u00edho poskytovatele internetu. Pakety si v\u017edy sna\u017e\u00ed naj\u00edt tu nejlep\u0161\u00ed a nejkrat\u0161\u00ed cestu \ud83d\ude42<\/p>\n

Pr\u00e1v\u011b tato konkuren\u010dn\u00ed v\u00fdhoda se ukazuje jako kl\u00ed\u010dov\u00e1, proto\u017ee v\u011bt\u0161ina t\u00fdmu je t\u0159eba ze stejn\u00e9ho kraje anebo m\u011bsta. Obdobn\u011b to dob\u0159e funguje t\u0159eba pro online v\u00fduku. Studenti i u\u010ditel jsou v\u011bt\u0161inou z bl\u00edzk\u00e9 lokality. A kdo je d\u00e1l, ten hold bude pro ostatn\u00ed trochu „rozmazan\u00fd“.<\/p>\n

T\u00edm, \u017ee komunikace nejde p\u0159es na\u0161e servery, tak ji nem\u016f\u017eeme odposlouch\u00e1vat, ani kdybychom cht\u011bli a\u00a0 je\u0161t\u011b u\u0161et\u0159\u00edme za p\u0159enosy. No neberte to \ud83d\ude42<\/p>\n

Co se t\u00fdk\u00e1 aktu\u00e1ln\u00edho provozu, tak z na\u0161\u00ed strany logujeme jen to, co mus\u00edme ze z\u00e1kona a do budoucna to ani nepl\u00e1nujeme n\u011bjak m\u011bnit. Koncept Jitsi spl\u0148uje GDPR a z na\u0161\u00ed strany jde provoz jen p\u0159es na\u0161e servery v Datacentru WEDOS 1 v Hlubok\u00e9 Nad Vltavou. P\u0159enosy jsou nav\u00edc \u0161ifrovan\u00e9.<\/p>\n

Jako beta funkce je nav\u00edc k dispozici End To End Encryption, tak\u017ee p\u0159enos m\u016f\u017eete i \u0161ifrovat nad r\u00e1mec HTTPS. Tuto funkci jsme testovali pro posledn\u00ed verzi Google Chrome. U\u017eivatel\u00e9 s Windows si ji mus\u00ed speci\u00e1ln\u011b povolit v nastaven\u00ed. Jedn\u00e1 se o Experimental Web Platform features<\/em>. V Chrome j\u00ed najdete pokud vlo\u017e\u00edte do adresn\u00edho \u0159\u00e1dku:<\/p>\n

chrome:\/\/flags\/#enable-experimental-web-platform-features<\/pre>\n
Podle ofici\u00e1ln\u00edch str\u00e1nek, to um\u00ed ka\u017ed\u00fd prohl\u00ed\u017ee\u010d s j\u00e1drem Chromium 83 a vy\u0161\u0161\u00ed (Microsoft Edge, Google Chrome, Brave a Opera).<\/p>\n
V\u0161ichni \u00fa\u010dastn\u00edci s povolen\u00fdm End To End Encryption pak budou m\u00edt mo\u017enost spolu norm\u00e1ln\u011b komunikovat. Ostatn\u00ed uvid\u00ed jen tohle:<\/p>\n

Kdy\u017e jsme zjistili, jak nen\u00e1ro\u010dn\u00e1 slu\u017eba je (aktu\u00e1ln\u011b bychom zvl\u00e1dli n\u011bjak\u00fdch n\u011bkolik tis\u00edc \u00fa\u010dastn\u00edk\u016f nar\u00e1z a pokud p\u0159id\u00e1me p\u00e1r server\u016f, tak zvl\u00e1dneme i stovky tis\u00edc \u00fa\u010dastn\u00edk\u016f sou\u010dasn\u011b), rozhodli jsem se, \u017ee bude v n\u011bjak\u00e9 alespo\u0148 omezen\u00e9 m\u00ed\u0159e k WEDOS CD zdarma. Pokro\u010dilej\u0161\u00ed funkcionality, jako je nahr\u00e1v\u00e1n\u00ed obrazu, bychom dali k placen\u00e9 verzi WEDOS CD. Tam u\u017e je v\u011bt\u0161\u00ed z\u00e1t\u011b\u017e na servery, proto\u017ee se nahr\u00e1vky ukl\u00e1daj\u00ed ve form\u00e1tu mp4 a ka\u017ed\u00e9 nahr\u00e1v\u00e1n\u00ed vyu\u017eije t\u00e9m\u011b\u0159 cel\u00e9 vl\u00e1kno CPU.<\/p>\n
Pokud tedy pot\u0159ebujte modern\u00ed syst\u00e9m pro konferen\u010dn\u00ed videohovory anebo pro online v\u00fduku, tak u n\u00e1s bude zdarma. Stejn\u011b tak pro rodinn\u00e9 hovory, pokec s kamar\u00e1dy u piva apod.<\/p>\n
A abychom nezapomn\u011bli. P\u0159es n\u00e1\u0161 syst\u00e9m p\u016fjdou po\u0159\u00e1dat i online demonstrace.
