Maemo a IT a ntse a rarahana le ho feta. Maemong ana, ho bohlokoa hore sistimi ea boiketsetso ea IT e be le tlhaiso-leseling ea morao-rao mabapi le li-node tse teng marang-rang le ho sebetsa. Sebakeng sa Red Hat Ansible Automation Platform, taba ena e rarolloa ka seo ho thoeng ke inventory () - manane a li-node tse laoloang.
Ka mokhoa oa eona o bonolo, inventory ke faele e tsitsitseng. Sena se nepahetse ha o qala ho sebetsa le Ansible, empa ha othomathike e ntse e eketseha, e fetoha e sa lekaneng.
Ke kahoo:

- Mokhoa oa ho arola likarolo tsa lisebelisoa tsa IT e le hore u khethoe ka ho khetheha li-node bakeng sa ho sebelisa mochine o itseng?
Dynamic inventory e fana ka likarabo tsa lipotso tsena ka bobeli () - script kapa plugin e batlang li-node hore e iketsetse, e buang ka mohloli oa 'nete. Ntle le moo, lethathamo la lintho tse feto-fetohang le arola li-node ka lihlopha e le hore u ka khetha ka nepo litsamaiso tsa sepheo bakeng sa ho etsa othomathike e itseng ea Ansible.
fa mosebelisi ea Ansible bokhoni ba ho fihlella li-platform tsa kantle ho batla ka matla li-node tsa sepheo le ho sebelisa sethala sena e le mohloli oa 'nete ha o theha lethathamo la lintho. Lethathamo le tloaelehileng la mehloli ho Ansible le kenyelletsa sethala sa maru AWS EC2, Google GCP le Microsoft Azure, hape ho na le li-plugins tse ling tse ngata tsa Ansible.
Ansible Tower e tla le palo ea , e sebetsang hantle ka ntle ho lebokose 'me, ho phaella ho liforomo tsa maru tse thathamisitsoeng ka holimo, li fana ka kopanyo le VMware vCenter, Red Hat OpenStack Platform le Red Hat Satellite. Bakeng sa li-plugins tsena, o hloka feela ho fana ka lintlha tsa ho hokela sethaleng se lebisitsoeng, ka mor'a moo li ka sebelisoa e le mohloli oa lintlha tsa thepa ho Ansible Tower.
Ntle le li-plugins tse tloaelehileng tse kenyellelitsoeng le Ansible Tower, ho na le li-plugins tse ling tse tšehetsoeng ke sechaba sa Ansible. Ka phetoho ea ho li-plugins tsena li ile tsa qala ho kenyelletsoa likolekeng tse lumellanang.
Ka poso ena, re tla nka mohlala oa ho sebetsa le plugin ea inventory bakeng sa ServiceNow, sethaleng se tummeng sa tsamaiso ea litšebeletso tsa IT moo bareki ba atisang ho boloka tlhahisoleseding e mabapi le lisebelisoa tsohle tsa bona ho CMDB.
