Okwu Mmalite
Enwere ike ịhụ ihe nkwụnye ihe na-agbanwe agbanwe na eserese dị n'okpuru ebe a, nke na-egosi ihe atụ dị mfe:
Load Balancer na-anabata arịrịọ ma kesaa ya n'ofe oge. Anyị nwere otu ihe atụ dị iche, enwere ọrụ Lambda yana enwere otu AutoScaling (otu sava).
Ụdị AWS ELB
1. Ka anyị leba anya n'ụdị isi:
Omuma Load Balancer. Ihe nkwụnye ego mbụ sitere na AWS, na-arụ ọrụ na ọkwa OSI 4 na 7, HTTP, HTTPS, TCP na SSL na-akwado. Ọ na-enye nguzozi ibu bụ isi n'ofe ọtụtụ Amazon EC2 ma na-arụ ọrụ ma arịrịọ yana ọkwa njikọ. Ka anyị mepee ya (nke a na-eji isi awọ pụta ìhè):
A na-ewere ihe nkwụnye ego a dị ka ihe ochie, n'ihi ya, a na-atụ aro ka iji ya mee ihe naanị n'ọnọdụ ụfọdụ. Dịka ọmụmaatụ, maka ngwa arụnyere na netwọk EC2-Classic. Na ụkpụrụ, ọ dịghị onye na-egbochi anyị ịmepụta ya:
2. Network Load Balancer. Kwesịrị ekwesị maka ibu ọrụ dị arọ, na-arụ ọrụ na OSI Layer 4 (enwere ike iji na EKS na ECS), TCP, UDP na TLS na-akwado.
Network Load Balancer na-eji ụzọ okporo ụzọ gaa na ebumnuche na Amazon VPC ma nwee ike ịhazi nde nde arịrịọ kwa sekọnd na obere latency dị ala. Na mgbakwunye, ọ kachasị mma ijikwa usoro okporo ụzọ na ibu na mberede na-agbanwe.
3. Ngwa nkwụnye ego. Na-arụ ọrụ na oyi akwa 7, nwere nkwado Lambda, na-akwado nkụnye eji isi mee na iwu ọkwa ụzọ, na-akwado HTTP na HTTPS.
Na-enye usoro arịrịọ dị elu lekwasịrị anya n'iwepụta ngwa arụnyere na ụlọ ọgbara ọhụrụ, gụnyere microservices na arịa. Na-eduzi okporo ụzọ na ebumnuche na Amazon VPC dabere na ọdịnaya nke arịrịọ ahụ.
Maka ọtụtụ ndị ọrụ, Ngwa Load Balancer bụ nhọrọ mbụ iji dochie ihe nhazi ihe nrụnye Classic, n'ihi na TCP anaghị adịkarị ka HTTP.
Ka anyị mepụta ya kwa, n'ihi nke anyị ga-enweworị ihe nkwụnye ibu abụọ:
Ibu ibu akụrụngwa
Ngwa nha nha nha nkịtị (nke a na-ahụkarị maka ndị na-edozi ihe niile):
- Iwu ịbanye

Mgbe ahụ, anyị ezipụta S3Bucket - Amazon ihe nchekwa:
- Atụmatụ

- Subnets
- subnets n'ime VPC gị (na, ya mere, mpaghara nnweta). A na-akọwapụta ihe ntanetịime n'oge okike. Ọ bụrụ na mpaghara nwere oke VPC, mgbe ahụ subnets nwere oke site na mpaghara nnweta. Mgbe ị na-emepụta ihe nkwụnye ụgwọ, ọ ka mma ịmepụta ya na ọ dịkarịa ala abụọ subnets (na-enyere aka ma ọ bụrụ na nsogbu bilitere na otu Mpaghara Nnweta);
- Ndị na-ege ntị

Ọmụmaatụ maka Nhazi Ibu Omuma:
Mana na Ngwa Load Balancer anyị na-ahụ interface dịtụ iche yana mgbagha dị iche iche:
Ibu Ibu Balancer v2 components (ALB na NLB)
Ugbu a, ka anyị lebakwuo anya na ụdị 2 balancers Ngwa Load Balancer na Network Load Balancer. Ndị a balancers nwere nke ha akụrụngwa atụmatụ. Dịka ọmụmaatụ, echiche dị otú ahụ dị ka otu Target Group pụtara - ihe atụ (na ọrụ). N'ihi akụrụngwa a, anyị nwere ohere ịkọwapụta nke ndị otu Target anyị chọrọ iduzi okporo ụzọ gaa.
N'okwu dị mfe, n'ime otu Target anyị na-akọwapụta oge ebe okporo ụzọ ga-abịa. Ọ bụrụ na n'otu Classic Load Balancer, ị ga-ejikọ ike ozugbo na onye na-edozi ihe, mgbe ahụ na ngwa Load Balancer ị ga-ebu ụzọ:
- mepụta Ntụle Ibu Ibu;

Echiche a na-arụ ọrụ nwere ike ịdị ka mgbagwoju anya, mana n'eziokwu ọ ka adaba.
Akụkụ na-esote bụ Iwu ndị na-ege ntị (iwu maka uzo). Nke a na-emetụta naanị Ngwa Load Balancer. Ọ bụrụ na netwọk Load Balancer ị na-emepụta naanị onye na-ege ntị, ọ na-ezigakwa okporo ụzọ gaa na otu Target otu, mgbe ahụ na ngwa Load Balancer ihe niile. .
Ugbu a, ka anyị kwuo okwu ole na ole gbasara akụrụngwa na-esote - IP na-agbanwe agbanwe (adreesị static maka NLB). Ọ bụrụ na usoro ntụgharị iwu ndị na-ege ntị na-emetụta naanị Ngwa Load Balancer, mgbe ahụ Elastic IP metụtara naanị Network Load Balancer.
Ka anyị mepụta nhazi ihe nrụnye netwọkụ:
Naanị n'oge usoro okike anyị ga-ahụ na enyere anyị ohere ịhọrọ IP Elastic:
Elastic IP na-enye otu adreesị IP nke enwere ike jikọta ya na oge EC2 dị iche iche n'oge. Ọ bụrụ na ihe atụ EC2 nwere adreesị IP Elastic na ihe atụ ahụ kwụsịrị ma ọ bụ kwụsị, ị nwere ike jikọta ihe atụ EC2 ọhụrụ na adreesị IP Elastic ozugbo.

ebe a na isiokwu nke ihe mere Elastic IP chọrọ. Lee, anyị na-ahụ adreesị IP 3, mana ha agaghị anọ ebe a ruo mgbe ebighị ebi:
Amazon na-agbanwe ha ka oge na-aga, ikekwe ọ bụla 60 sekọnd (ma na omume, n'ezie, obere mgbe). Nke a pụtara na adreesị IP nwere ike ịgbanwe. Na n'ihe banyere Network Load Balancer, ị nwere ike kechie adreesị IP wee gosi ya na iwu gị, atumatu, wdg.
Mee nchọta
ELB na-enye nkesa akpaaka nke okporo ụzọ na-abata gafee ọtụtụ ebumnuche (akpa, Amazon EC2, adreesị IP, na ọrụ Lambda).
