Azure Load Balancer & Application Gateway

Step 1

lb-web نام کا Standard SKU public Load Balancer بنائیں، frontend IP اور backend pool bepool کے ساتھ۔ Backend pool میں وہ servers ہوں گے جنہیں ٹریفک ملے گا۔lb-web naam ka Standard SKU public Load Balancer banayein, frontend IP aur backend pool bepool ke saath. Backend pool mein woh servers honge jinhe traffic milega.Create a Standard SKU public Load Balancer named lb-web with a frontend IP and a backend pool bepool. The backend pool will hold the servers that receive traffic.

az network lb create --resource-group rg-netsec-lab --name lb-web --sku Standard --public-ip-address-allocation Static --public-ip-sku Standard --backend-pool-name bepool --frontend-ip-name fepublic --location southeastasia

🖱️ Load balancers > Create — SKU Standard، public frontend، backend pool bepoolLoad balancers > Create — SKU Standard, public frontend, backend pool bepoolLoad balancers > Create — SKU Standard, public frontend, backend pool bepool

Step 2

Port 80، path / پر HTTP health probe شامل کریں۔ Probe چیک کرتا ہے کہ کون سے backends healthy ہیں پھر انہیں ٹریفک بھیجتا ہے۔Port 80, path / par HTTP health probe add karein. Probe check karta hai ke kaunse backends healthy hain phir unhe traffic bhejta hai.Add an HTTP health probe on port 80, path /. The probe checks which backends are healthy before sending them traffic.

az network lb probe create --resource-group rg-netsec-lab --lb-name lb-web --name probe-http --protocol Http --port 80 --path / --interval 15 --threshold 4

🖱️ Load balancers > lb-web > Health probes > Add — port 80، path / پر HTTP probeLoad balancers > lb-web > Health probes > Add — port 80, path / par HTTP probeLoad balancers > lb-web > Health probes > Add — HTTP probe on port 80, path /

Step 3

Load balancing rule شامل کریں: frontend port 80 سے backend port 80۔ یہ rule frontend IP، backend pool اور probe کو جوڑتا ہے۔Load balancing rule add karein: frontend port 80 se backend port 80. Yeh rule frontend IP, backend pool aur probe ko jorta hai.Add a load balancing rule: frontend port 80 to backend port 80. This rule ties the frontend IP, backend pool, and probe together.

az network lb rule create --resource-group rg-netsec-lab --lb-name lb-web --name rule-http --protocol Tcp --frontend-port 80 --backend-port 80 --frontend-ip-name fepublic --backend-pool-name bepool --probe-name probe-http

🖱️ Load balancers > lb-web > Load balancing rules > Add — frontend 80 سے backend 80Load balancers > lb-web > Load balancing rules > Add — frontend 80 se backend 80Load balancers > lb-web > Load balancing rules > Add — frontend 80 to backend 80

Step 4

Load balancer، اس کا frontend public IP، backend pool، probe اور rule ویریفائی کریں۔ Frontend IP نوٹ کریں — یہ single entry point بنتا ہے۔Load balancer, us ka frontend public IP, backend pool, probe aur rule verify karein. Frontend IP note karein — yeh single entry point banta hai.Verify the load balancer, its frontend public IP, backend pool, probe, and rule. Note the frontend IP — it becomes the single entry point.

az network lb list --resource-group rg-netsec-lab --output table

🖱️ Load balancers — تصدیق کریں کہ lb-web اپنے public IP کے ساتھ نظر آ رہا ہےLoad balancers — tasdeeq karein ke lb-web apne public IP ke saath nazar aa raha haiLoad balancers — verify lb-web appears with its public IP

Step 5

Application gateways > Create کھولیں اور pieces کا جائزہ لیں: SKU (Standard_v2)، listeners (frontend port/protocol)، routing rules، اور backend pools۔ صرف concepts — deploy نہ کریں (لاگت ہوتی ہے)۔Application gateways > Create kholein aur pieces review karein: SKU (Standard_v2), listeners (frontend port/protocol), routing rules, aur backend pools. Sirf concepts — deploy na karein (cost hoti hai).Open Application gateways > Create and review the pieces: SKU (Standard_v2), listeners (frontend port/protocol), routing rules, and backend pools. Concepts only — do not deploy (costs money).

🖱️ Application gateways > Create — SKU (Standard_v2)، listeners، rules، backend pools کا جائزہ لیںApplication gateways > Create — SKU (Standard_v2), listeners, rules, backend pools review kareinApplication gateways > Create — review SKU (Standard_v2), listeners, rules, backend pools

Step 6

Listener rule types کا موازنہ کریں: Basic (ایک backend)، Path-based (مثلاً /images/* pool A کو، /api/* pool B کو)، اور Multi-site (hostname سے route)۔ یہ Application Gateway کی Layer 7 power ہے۔Listener rule types compare karein: Basic (ek backend), Path-based (masalan /images/* pool A ko, /api/* pool B ko), aur Multi-site (hostname se route). Yeh Application Gateway ki Layer 7 power hai.Compare listener rule types: Basic (one backend), Path-based (e.g. /images/* to pool A, /api/* to pool B), and Multi-site (route by hostname). This is Application Gateway's Layer 7 power.

🖱️ Application gateways > Create > Rules tab — Basic بمقابلہ Path-based بمقابلہ Multi-site listeners کا موازنہ کریںApplication gateways > Create > Rules tab — Basic vs Path-based vs Multi-site listeners compare kareinApplication gateways > Create > Rules tab — compare Basic vs Path-based vs Multi-site listeners
