Canonical har annonceret tilg\u00e6ngeligheden af MicroCloud v\u00e6rkt\u00f8jet, der muligg\u00f8r hurtig udrulning af compute-klynger og cloud-systemer med delt datalagring og et sikkert virtuelt netv\u00e6rk p\u00e5 ens eget udstyr. V\u00e6rkt\u00f8jet leveres som en snap-pakke, der inkluderer de komponenter, der er n\u00f8dvendige for at styre arbejdet i klyngeknuderne. Kommerciel teknisk support for l\u00f8sninger baseret p\u00e5 MicroCloud tilbydes gennem Ubuntu Pro-servicen, men dem, der kan klare sig uden support, kan bruge v\u00e6rkt\u00f8jet uden begr\u00e6nsninger. Projektets arbejde er skrevet i Go-sprog og distribueres under AGPL 3.0 licensen. <\/p>\n

MicroClouds anvender som standard midler til at sikre fejltolerance, hvilket g\u00f8r det muligt at oprette klynger med mindst tre knuder (den \u00f8vre gr\u00e6nse n\u00e6vner klynger med op til 50 knuder). Den softwarestak, der bruges til at styre klyngen, er baseret p\u00e5 et centralt styringssystem for containere og virtuelle maskiner LXD, en platform til at bygge virtuelle netv\u00e6rk OVN (Open Virtual Network) og distribueret fejltolerant lagring Ceph. MicroClouds giver v\u00e6rkt\u00f8jer til automatisk konfiguration af LXD, Ceph og OVN p\u00e5 alle klyngeknuder. <\/p>\n

For at identificere af nye servere<\/a> I netv\u00e6rk, der kan tilsluttes til klyngen, bruges mDNS, hvilket g\u00f8r det muligt at s\u00e6tte hele klyngen op ved blot at k\u00f8re \u00e9n kommando «microcloud init» p\u00e5 en af noderne, efter at snap-pakkerne lxd, microceph, microcloud og microovn er installeret. Den prim\u00e6re platform betragtes som Ubuntu Server-distributionen, men v\u00e6rkt\u00f8js\u00e6ttet er ikke knyttet til Ubuntu og kan anvendes p\u00e5 enhver distribution, hvor installation af snap-v\u00e6rkt\u00f8jet er tilg\u00e6ngeligt (Arch, CentOS, Fedora, Debian, openSUSE, RHEL osv.). Det er ogs\u00e5 muligt at oprette klynger baseret p\u00e5 systemer, der bruger atomar opdateret Ubuntu Core. <\/p>\n

Efter at have k\u00f8rt kommandoen «microcloud init» vil v\u00e6rkt\u00f8js\u00e6ttet registrere tilstedev\u00e6relsen af andre servere i det lokale netv\u00e6rk, anmode om at tilf\u00f8je diske til det f\u00e6lles Ceph-lager og foresl\u00e5 at konfigurere parametre for det virtuelle netv\u00e6rk. For at inkludere serverne i klyngen skal de ovenn\u00e6vnte snap-pakker f\u00f8rst v\u00e6re installeret p\u00e5 serverne. Klyngens konfiguration kan gemmes i YAML-format til senere deployment af lignende systemer. For at tilf\u00f8je ekstra noder efter afslutningen af initialiseringen kan kommandoen «microcloud add» bruges. <\/p>\n

Det f\u00e6lles filsystem oprettes med aktiveret replikation og fejltolerance, som sikrer, at data ikke g\u00e5r tabt i tilf\u00e6lde af, at enkelte noder fejler, ved at gemme flere eksemplarer af data p\u00e5 forskellige noder. For at implementere et lagersystem baseret p\u00e5 Ceph i klyngen, skal der ud over de lokale diske ogs\u00e5 v\u00e6re mindst tre separate diske, der er afsat til distribueret datalagring, p\u00e5 tre forskellige computere. <\/p>\n

N\u00e5r klyngen er klar, f\u00e5r brugerne mulighed for at k\u00f8re deres applikationer ved hj\u00e6lp af systemcontainere eller virtuelle maskiner, samt f\u00e5 adgang til det f\u00e6lles Ceph-lager og det centraliserede administrationsv\u00e6rkt\u00f8j baseret p\u00e5 LXD. Platformen Kubernetes (Microk8s-versionen) kan k\u00f8re oven p\u00e5 klyngen for at styre containerinfrastrukturen. For brugerautentifikation virtual machines<\/a> eller containere i klyngen kan OpenID Connect (OIDC) anvendes til autentifikation og autorisation baseret p\u00e5 OpenFGA.

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

Der er mulighed for fleksibel styring af de tildelte ressourcer CPU, hukommelse og input\/output, videregivelse af USB-enheder, GPU'er og lagringsenheder til milj\u00f8erne. Isolerede og virtuelle milj\u00f8er kan flyttes mellem noderne i live-migreringstilstand og gemmes ved hj\u00e6lp af snapshots. Metrikker om klyngens ydeevne og h\u00e6ndelseslogge kan eksporteret til overv\u00e5gning ved hj\u00e6lp af Prometheus og Grafana. <\/p>\n

Ud over at skabe arbejdsklynger og private cloud-systemer er v\u00e6rkt\u00f8jet ogs\u00e5 egnet til hurtigt at udf\u00f8re eksperimenter p\u00e5 udviklerens systemer. For eksempel kan MicroCloud bruges til at simulere en klynge p\u00e5 udviklerens b\u00e6rbare computer, teste udviklede cloud-applikationer, eksperimentere med nye teknologier eller simulere komplekse infrastrukturer.
