Zochitika pakusintha ma SAP hosting: momwe mungasamukire machitidwe popanda kukhala zowawa kwambiri

Kapena ndizotheka? Zoonadi, kusamuka machitidwe a SAP ndizovuta komanso zovuta, zomwe zimafuna kuti anthu onse azichita nawo ntchito yogwirizana. Ndipo ngati kusamuka kukuchitika pakanthawi kochepa, ntchitoyi imakhala yovuta kwambiri. Sikuti aliyense amasankha kuchita zimenezi. Pakhoza kukhala zifukwa zingapo. Mwachitsanzo, ndondomeko yokha ndi yaitali komanso yovuta. Komanso pali chiopsezo cha nthawi yosakonzekera dongosolo. Kapena makasitomala sakutsimikiza kuti, atachitidwa opaleshoni yotere, adzalandira phindu lolingana ndi zoyesayesa zomwe agwiritsa ntchito. Komabe, pali zosiyana.

Pansi pa odulidwawo, tidzakambirana za zovuta zomwe makasitomala amakumana nazo panthawi yosamukira ndi kusunga machitidwe a SAP, kukambirana chifukwa chake stereotypes samagwirizana nthawi zonse ndi zenizeni, ndikugawana nawo phunziro la momwe tinatha kusamukira ku machitidwe a kasitomala zomangamanga zatsopano m'miyezi itatu yokha.

SAP machitidwe kuchititsa

Zaka zisanu zapitazo, zinali zovuta kuganiza kuti makasitomala ayamba kugwiritsa ntchito zinthu zothandizira ku SAP. Nthawi zambiri zidakhazikitsidwa pamaziko. Komabe, ndi chitukuko cha zitsanzo za kunja ndi msika wa mautumiki amtambo, maonekedwe a makasitomala anayamba kusintha. Ndi mikangano yotani yomwe imapangitsa kusankha kokomera mtambo kwa SAP?

• Kwa oyamba kumene omwe angokonzekera kukhazikitsa SAP, zomangamanga zamtambo zimakhala pafupifupi chisankho chokhazikika - scalability of resources to the current needs of the system and kukayikira kupatutsa chuma ku chitukuko cha luso lopanda maziko.
• M'makampani omwe ali ndi mawonekedwe akuluakulu, mothandizidwa ndi kuchititsa machitidwe a SAP, ma CIO amafika pamlingo wosiyana kwambiri wowongolera zoopsa, chifukwa Wothandizana naye ali ndi udindo wa SLA.
• Mtsutso wachitatu wofala kwambiri ndi kukwera mtengo kwa zomangamanga kuti akwaniritse kupezeka kwakukulu ndi zochitika za DR.
• Factor 2027 - wogulitsa adalengeza kutha kwa kuthandizira machitidwe olowa mu 2027. Izi zikutanthauza kusamutsa nkhokwe ku HANA, zomwe zimaphatikizapo ndalama zosinthira zamakono komanso kugula mphamvu zatsopano zamakompyuta.

Msika wa SAP ku Russia tsopano ukhoza kuonedwa kuti ndi wokhwima kwambiri. Ndipo izi zimapereka mwayi wokwanira kwa makasitomala omwe akufuna kusintha nsanja zawo zochitira. Komabe, ma projekiti oterowo angayambitse nkhawa pakati pa mabizinesi chifukwa cha zovuta zakusamuka. Izi zimakakamiza makasitomala kuti aike zofuna zowonjezereka kwa opereka chithandizo, omwe sayenera kukhala ndi luso lapadera lothandizira ndi kusunga machitidwe a SAP, komanso odziwa bwino ntchito ya kusamuka.

Ndizovuta zotani zosinthira kuchititsa SAP?

Ma hosting ndi osiyana. Kusagwirizana ndi kuchuluka kwa ntchito zomwe zalengezedwa, "buts" ndi nyenyezi zambiri zosungidwa m'mawu ang'onoang'ono, zida zochepa ndi kuthekera kwa woperekera alendo, kusowa kusinthasintha pankhani zolumikizana ndi kasitomala, maofesi, zolephera zaukadaulo, kutsika kwa luso laukadaulo. akatswiri, komanso ma nuances ena ambiri - awa ndi gawo laling'ono chabe la zovuta zomwe makasitomala angakumane nazo akamayendetsa mabizinesi awo popereka zida zakunja. Nthawi zambiri, kwa kasitomala, zonsezi zimakhalabe mumthunzi, m'nkhalango ya mgwirizano wamasamba ambiri, ndipo zimatuluka pogwiritsira ntchito mautumiki.

Panthawi ina, zimakhala zoonekeratu kwa wogula kuti mlingo wa utumiki umene amalandira uli kutali ndi zomwe akuyembekezera. Uwu ndi mtundu wothandizira kupeza njira zothetsera vutoli ndipo, zikalephera, mavuto akachulukana mpaka kufika pomaliza ndipo zimakhala zowawa kwambiri, amapita kukachitapo kanthu kuti apange njira zina zosinthira wopereka chithandizo. .

N’chifukwa chiyani amadikira mpaka nthawi yomaliza? Chifukwa chake ndi chophweka - njira yosamukira ku machitidwe kwa makasitomala nthawi zonse imakhala yowonekera komanso yomveka. Zimakhala zovuta kuti kasitomala awone zoopsa zenizeni zomwe zimagwirizanitsidwa ndi kusamuka. Tikhoza kunena kuti kusamuka kwa makasitomala ndi mtundu wa bokosi lakuda: sizikudziwika bwino, mtengo, nthawi yochepetsera dongosolo, zoopsa komanso momwe mungachepetsere, ndipo nthawi zambiri zimakhala zakuda komanso zowopsya. Zili ngati, ngati sizikuyenda bwino, ndiye kuti mitu idzagudubuza pamwamba komanso kwa ochita masewerawo.

SAP ndi dongosolo lamabizinesi, zovuta komanso, kunena mofatsa, osati zotsika mtengo. Mabajeti abwino amagwiritsidwa ntchito pakukhazikitsa, kusinthidwa, ndi kukonza, ndipo moyo wabizinesi umadalira kupezeka kwawo komanso magwiridwe antchito oyenera. Tsopano lingalirani zotsatirapo za kuimitsa kupanga zina zazikulu. Izi ndizowonongeka kwachuma, zomwe zitha kuwerengedwa mu manambala okhala ndi ziro zambiri, komanso mbiri ndi zoopsa zina zofananira.

Tidzasanthula zovuta zomwe zingabwere pagawo lililonse pa nkhani ya kusamuka machitidwe a SAP kuchokera kwa mmodzi wa makasitomala athu.

Kukonzekera ndi kupanga

Kusamuka ndi njira yokhala ndi magawo osiyanasiyana. Ndipo chimodzi mwazofunikira kwambiri ndi gawo la kupanga ndi kukonzekera zopangira chandamale (zatsopano).

Tinkafunika kulowa pansi pa kukhazikitsidwa kwa machitidwe omwe alipo, kamangidwe kake. Muzokhazikika zomwe taziganizira, tidabwerezanso njira zomwe zidalipo kwinakwake, kuziwonjezera ndikuziwongolera pazifukwa zina, kuzikonzanso kwinakwake, kulingalira ndikusankha njira zowonetsetsa kulekerera zolakwika ndi kupezeka, ndikuphatikizanso zida zonse momwe tingathere.

Pakupanga mapangidwe, machitidwe osiyanasiyana osiyanasiyana adachitidwa, omwe pamapeto pake adapangitsa kuti athe kukonzekera momwe angathere kusamuka ndikuganizira zamitundu yonse ndi misampha (zambiri pambuyo pake).

Zomwe tidamaliza nazo ndizomwe zidapangidwa payekhapayekha pamtambo kutengera malo athu a data:

• ma seva odzipatulira akuthupi a SAP HANA;
• VMware virtualization nsanja ya ma seva ogwiritsira ntchito ndi ntchito zachitukuko;
• njira zolumikizirana zobwerezabwereza pakati pa malo opangira data a L2 VPN;
• njira ziwiri zazikulu zosungiramo zolekanitsira malonda ndi "china chilichonse";
• SRC yochokera ku Veritas Netbackup yokhala ndi seva yosiyana, shelufu ya disk ndi laibulale ya tepi.

Ndipo umu ndi momwe tidachitira zonsezi kuchokera pamalingaliro aukadaulo.

Sap

• Kuti tigwiritse ntchito bwino kusungirako kwa HANA yobala, tidagwiritsa ntchito ma disks omwe adagawana popanda kubwereza kwadongosolo la database pogwiritsa ntchito SAP. Zonsezi zidakulungidwa mu gulu la Active-Standby SUSE HAE lochokera pa Pacemaker. Inde, nthawi yobwezeretsa ndi yotalika pang'ono kusiyana ndi kubwerezabwereza, koma timasunga malo osungiramo theka ndipo, chifukwa chake, timasunga bajeti ya kasitomala.
• M'malo opangira zisanachitike, magulu a HANA adasiyidwa, koma mwaukadaulo masinthidwe opanga adabwerezedwa.
• Malo oyesera ndi chitukuko adagawidwa pamaseva ena angapo opanda magulu mu kasinthidwe ka MCOS.
• Ma seva onse ogwiritsira ntchito adasinthidwa ndikusungidwa mu VMware.

Сети

• Tidalekanitsa ma contours owongolera ndi kupanga maukonde ndi masiwichi ambiri, kutembenuzira opindulitsa kumalo osungira makasitomala.
• Tinayika chiwerengero chokwanira cha maukonde ochezera a pa Intaneti kuti tisasakanize kuyenda kwakukulu kwa magalimoto.
• Kusamutsa deta kuchokera kumakina osungira, tinapanga mafakitale apamwamba a FC SAN.

Zithunzi za SHD

• Katundu wopanga komanso wopangidwa kale wa SAP adasiyidwa pazithunzi zonse.
• Malo oyesera a Madivelopa ndi ntchito za zomangamanga zidayikidwa pagulu lamitundu yosiyanasiyana.

IBS

• Amapangidwa pogwiritsa ntchito Veritas Netbackup.
• Tidawonjezera pang'ono pazolemba zomwe zidapangidwa kuti zisungidwe zosunga zobwezeretsera za MCOS.
• Timayika makope ogwiritsira ntchito pa shelufu ya disk kuti ayambe kuchira msanga, ndipo timagwiritsa ntchito matepi posungira nthawi yaitali.

Kuwunikira

• Zida zonse, OS ndi SAP zidayikidwa pansi pa Zabbix.
• Tasonkhanitsa ma dashboard ambiri othandiza ku Grafana.
• Chidziwitso chikachitika, Zabbix imatha kupanga pempho mu kasamalidwe ka zochitika; takhazikitsa ku Jira. Zambirizi zikubwerezedwanso mu njira ya Telegraph.

Ntchito zogwirira ntchito

• Kuti mugwiritse ntchito malo amkati, gulu la ma seva a DNS adakwezedwa, lomwe limalumikizidwa ndi ma seva a kasitomala.
• Tinapanga seva yosiyana yamafayilo yosinthira deta.
• Kusunga masinthidwe osiyanasiyana, Gitlab idawonjezedwa.
• Kuti mudziwe zambiri za Sensitive tinatenga HashiCorp Vault.

Njira yosamuka

Nthawi zambiri, kusamuka kumakhala ndi magawo awa:

• kukonzekera zolemba zonse zofunika za polojekiti;
• kukambirana ndi wothandizira panopa - kuthetsa nkhani za bungwe;
• kugula, kutumiza ndi kukhazikitsa zida zatsopano za polojekitiyi;
• kuyesa kusamuka ndi kukonza zolakwika;
• kusamutsa machitidwe, kusamuka kolimbana.

Kumapeto kwa Okutobala 2019, tidasaina mgwirizano, kenako tidapanga zomangamanga, ndipo titagwirizana ndi kasitomala, tidalamula zida zofunika.

Zomwe muyenera kuziganizira poyamba ndi nthawi yobweretsera zida. Pafupipafupi, kutumiza kwa hardware yovomerezeka ya SAP NAHA yomwe imakwaniritsa zofunikira za opanga mapulogalamu a hardware amatenga masabata a 10-12. Ndipo poganizira nyengo (kukhazikitsidwa kwa polojekitiyi kunagwa ndendende pa Chaka Chatsopano), nthawiyi ikanatha kuwonjezeka ndi mwezi wina. Chifukwa chake, kunali koyenera kufulumizitsa ndondomekoyi momwe tingathere: tinagwira ntchito ndi wogulitsa-wopereka ndipo tinagwirizana pa kutumiza mofulumira ndi ndege (m'malo mwa njira za pamtunda ndi nyanja).

November ndi December anathera pokonzekera kusamuka ndi kulandira zina mwa zipangizo. Tidakonzekera pa benchi yoyesera mumtambo wathu wapagulu, pomwe tidagwira ntchito zonse zazikulu ndikupeza zovuta ndi zovuta:

• adakonza dongosolo latsatanetsatane la kuyanjana pakati pa mamembala a gulu la polojekiti ndi nthawi ya mphindi ndi mphindi;
• anamanga benchi yoyesera ya nkhokwe ndi ma seva ogwiritsira ntchito pafupifupi mofanana ndi momwe mukufunira;
• adakonza njira zoyankhulirana zofunika ndi ntchito za zomangamanga kuti ayese ntchito zophatikiza;
• konzekerani zochitika za cutover;
• Mtambowo udatithandizanso kupanga ma tempulo amakina omwe adakonzedwa kale, omwe tidangolowetsa ndikutumiza komwe tidafuna.

Patatsala pang'ono tchuthi cha Chaka Chatsopano, gulu loyamba la zida zidafika kwa ife. Izi zinapangitsa kuti zitheke kuyika machitidwe ena pa hardware yeniyeni. Popeza sizinafike zonse, tidalumikiza zida zosinthira, zomwe tidakwanitsa kuvomerezana ndi ogulitsa ndi ogulitsa. Tinalandira zotsalira za zomangamanga zomwe tikuyembekezera pamapeto omaliza.
Kuti tikwaniritse tsiku lomaliza, mainjiniya athu adayenera kupereka tchuthi cha Chaka Chatsopano ndikuyamba ntchito yokonzekera zomwe akufuna kuchita pa Januware 2, mkati mwatchuthi. Inde, izi zimachitika nthawi zina pamoto ndipo palibe njira zina. Pachiwopsezo chinali machitidwe a machitidwe omwe moyo wabizinesi umadalira.

Kusamuka kwachiwopsezo kunkawoneka motere: choyamba, machitidwe ovuta kwambiri (mawonekedwe a chitukuko, kuyesa malo), ndiye machitidwe opindulitsa. Gawo lomaliza la kusamuka linachitika kumapeto kwa Januware komanso koyambirira kwa February.

Njira yosamuka idakonzedwa mpaka mphindi imodzi. Iyi ndi ndondomeko yochepetsera yomwe ili ndi mndandanda wa ntchito zonse, nthawi yomaliza ndi anthu omwe ali ndi udindo. Masitepe onse anali atapangidwa kale pakusamuka kwa mayeso, kotero pakusamuka kwamoyo kunali kofunikira kutsatira dongosolo ndikugwirizanitsa ndondomekoyi.

Kusamuka kunkachitika mwadongosolo m'magawo angapo. Pali machitidwe awiri pagawo lililonse.

Chotsatira cha sprint ya miyezi itatu chinali dongosolo lomwe likugwira ntchito mokwanira mu data center ya CROC. Nthawi zambiri, zotsatira zabwino zidapezedwa kudzera m'magulu; zopereka ndi kudzipereka kwa onse omwe adatenga nawo gawo pakuchitapo kanthu kunali kwakukulu.

Udindo wa kasitomala mu polojekiti

Kulankhulana ndi wothandizira kasitomala wathu amachoka sikunali kophweka. Izi ndizomveka; anali omaliza pamndandanda wa anthu omwe ali ndi chidwi ndi kutha kwa ntchitoyo. Makasitomala adagwira ntchito yokweza ndi kuyendetsa nkhani zonse zoyankhulirana ndikuthana ndi izi 100500%. Mwapadera zikomo kwa iye chifukwa cha ichi. Popanda kutenga nawo mbali motheka mu ntchitoyi, zotsatira za polojekitiyi zikanakhala zosiyana kwambiri.

Chifukwa cha kukhazikitsidwa kwa njira kumbali ya wothandizira "wakale", chithandizo cha zomangamanga chinachitidwa ndi akatswiri omwe anali kutali ndi mavuto, panthawiyo akadali makasitomala awo. Mwachitsanzo, njira yotumizira deta yomweyi imatha kutenga ola limodzi mpaka asanu. Kenako zinaoneka kuti zimenezi zinali zamatsenga, chinsinsi chimene sichinaululidwe kwa ife. Mwinanso akatswiri opanga ukadaulo adachita kusinkhasinkha panthawiyi, kuyiwala kuti kwinakwake ku Russia kuli masiku omaliza, akatswiri opanda saladi a Chaka Chatsopano, kasitomala akulira ndi kuvutika ...

Zotsatira za polojekiti

Gawo lomaliza la kusamukako linali kusamutsidwa kwa machitidwe okonza.

Tsopano timapereka ntchito imodzi yazenera pazopempha za makasitomala ndikuphimba gawo lonse la ntchito zokhudzana ndi kuthandizira zigawo za zomangamanga ndi maziko a SAP pamodzi ndi mnzathu - nzeru. Wothandizirayo wakhala akukhala mumtambo wachinsinsi kwa miyezi isanu ndi umodzi. Nazi ziwerengero zamilandu yamautumiki panthawiyi:

• Zochitika 90 (20% zidathetsedwa popanda kukhudza kasitomala)
• Kuthetsedwa mkati mwa SLA - 100%
• Kutsekedwa kwadongosolo kosakonzekera - 0

Ngati muli ndi mavuto ofanana ndi a kasitomala wathu, ndipo mukufuna kudziwa zambiri za momwe mungawathetsere, lembani ku: [imelo ndiotetezedwa]
