Tvrtka Canonical najavila je dostupnost alata MicroCloud, koji omogu\u0107uje brzo postavljanje ra\u010dunarskih klastera i oblaka s dijeljenim distribuiranim skladi\u0161tem podataka i sigurnom virtualnom mre\u017eom na vlastitom hardveru. Alat je oblikovan kao snap paket, koji uklju\u010duje komponente potrebne za upravljanje radom \u010dvorova klastera. Komercijalna tehni\u010dka podr\u0161ka rje\u0161enjima temeljenim na MicroCloudu dostupna je kroz uslugu Ubuntu Pro, ali oni koji mogu bez podr\u0161ke mogu koristiti alat bez ograni\u010denja. Radovi projekta napisani su u programskom jeziku Go i distribuiraju se pod AGPL 3.0 licencom. <\/p>\n

MicroCloudovi po defaultu koriste sredstva za osiguranje otpornosti, \u0161to omogu\u0107ava kreiranje klastera koji se sastoji od najmanje tri \u010dvora (maksimalno se spominju klasteri koji uklju\u010duju do 50 \u010dvorova). Softverski sloj kori\u0161ten za upravljanje klasterom temelji se na sustavu centraliziranog upravljanja kontejnerima i virtualnim strojevima LXD, platformi za izgradnju virtualnih mre\u017ea OVN (Open Virtual Network) i distribuiranom otpornom skladi\u0161tu Ceph. MicroCloudovi pru\u017eaju alate za automatsku konfiguraciju LXD, Ceph i OVN na svim \u010dvorovima klastera. <\/p>\n

Za odre\u0111ivanje novih poslu\u017eitelja<\/a> U mre\u017ei koja mo\u017ee biti povezana s klasterom koristi se mDNS, \u0161to omogu\u0107ava konfiguriranje cijelog klastera pokretanjem samo jedne naredbe «microcloud init» na jednom od \u010dvorova, prethodno instalirav\u0161i snap pakete lxd, microceph, microcloud i microovn. Kao glavna platforma razmatra se distribucija Ubuntu Server, ali alati nisu vezani uz Ubuntu i mogu se koristiti u bilo kojim distribucijama za koje je dostupna mogu\u0107nost instalacije snap alata (Arch, CentOS, Fedora, Debian, openSUSE, RHEL itd.). Tako\u0111er je mogu\u0107e stvaranje klastera na osnovi sustava koji koriste atomarno a\u017euriraju\u0107i OS Ubuntu Core. <\/p>\n

Nakon pokretanja naredbe «microcloud init» alati \u0107e odrediti prisutnost drugih servera u lokalnoj mre\u017ei, zatra\u017eiti dodavanje diskova u zajedni\u010dko skladi\u0161te Ceph i ponuditi konfiguraciju parametara virtualne mre\u017ee. Za uklju\u010divanje u klaster na serverima prethodno moraju biti instalirani ranije spomenuti snap paketi. Konfiguracija klastera mo\u017ee se spremiti u YAML formatu za naknadno postavljanje sli\u010dnih sustava. Za dodavanje dodatnih \u010dvorova nakon zavr\u0161etka inicijalizacije mo\u017ee se koristiti naredba «microcloud add». <\/p>\n

Zajedni\u010dka pohrana datoteka stvara se uklju\u010divanjem replikacije i otpornosti na gre\u0161ke, \u0161to omogu\u0107uje da se u slu\u010daju kvara pojedinih \u010dvorova podaci ne izgube, zahvaljuju\u0107i pohrani vi\u0161e primjeraka podataka na razli\u010ditim \u010dvorovima. Za implementaciju pohrane temeljenog na Ceph u klasteru, osim lokalnih diskova, na tri razli\u010dita ra\u010dunala moraju biti prisutna najmanje tri odvojena diska namijenjena za distribuiranu pohranu podataka. <\/p>\n

Nakon pripreme klastera korisnicima je omogu\u0107eno pokretanje vlastitih aplikacija kori\u0161tenjem sistemskih kontejnera ili virtualnih strojeva, kao i pristup zajedni\u010dkoj Ceph pohrani i alatu za centralizirano upravljanje temeljenom na LXD-u. Za upravljanje kontejnerskom infrastrukturom iznad klastera mo\u017ee se pokrenuti platforma Kubernetes (izdanje Microk8s). Za autentifikaciju korisnika virtualnih ma\u0161ina<\/a> ili kontejnera u klasteru mo\u017ee se koristiti OpenID Connect (OIDC) i autorizacija temeljenom na OpenFGA.

\"Canonical<\/center> <\/p>\n

Mogu\u0107e je fleksibilno upravljanje dostupnim resursima CPU-a, memorije i ulaza\/izlaza, propu\u0161tanje USB ure\u0111aja, GPU-a i skladi\u0161ta u okru\u017eenja. Izolirana i virtualna okru\u017eenja mogu se prenositi izme\u0111u \u010dvorova u na\u010dinu live migracije i pohranjivati koriste\u0107i snimke. Metri\u010dke podatke o radu klastera i logove doga\u0111aja mogu\u0107e je izvesti za pra\u0107enje pomo\u0107u Prometheus-a i Grafana. <\/p>\n

Osim stvaranja radnih klastera i privatnih cloud sustava, alat je tako\u0111er pogodna za brzo provo\u0111enje eksperimenata na razvojnim sustavima. Na primjer, MicroCloud se mo\u017ee koristiti za simulaciju klastera na prijenosnom ra\u010dunalu programera, testiranje razvijanih cloud aplikacija, eksperimente s novim tehnologijama ili simulaciju slo\u017eenih infrastruktura.
