Ib sab saum toj no, lub tswv yim ntawm kev sib npaug load yog dab tsi? Load ntsuas yog hais txog kev faib tawm cov kev sib txuas lus nkag mus thoob plaws ib pawg ntawm cov servers backend, tseem hu ua server ua liaj ua teb lossis server pas dej. Hauv qhov no, a load balancer ua cov haujlwm hauv qab no: faib cov neeg thov kev thov lossis network thauj muaj txiaj ntsig thoob plaws ntau lub servers.
Kuj paub, dab tsi yog qhov sib txawv ntawm load balancer hauv AWS cov kev pabcuam?
Hom Elastic Load Balancers
- Classic Load Balancer (CLB) Qhov no yog lub sijhawm dhau los load balancer uas tau siv rau EC2-classic zaus.
- Daim ntawv thov Load Balancer (ALB) Cov khoom sib npaug no tshwj xeeb tsim los rau kev siv web nrog HTTP thiab HTTPS tsheb.
- Network Load Balancer (NLB)
Qhov Load Balancer twg yog qhov zoo tshaj?
