This is to setup complete infra bulit on MS Azure like the below

OS : Ubuntu 18.04 TLS

### Servers and Tech Stack

• Web - Nginx And Php - VMSS - RULE

• API - php-fpm 7.2 - VMSS

• Queue Server - Beanstalk port 8080

• Worker server - VM port 22

• Cache - VM - KeyDB - VM port 6379

• Elasticsearch - VM port : 9300, 9200

• HAPROXY - AS LOAD BALANCER - vm

• database cluster on percona mysql - cluster XDB port 3306 - Name : PXC

- Security Group

• Different SUBNET- DB SUBNET
• PERCONA DB cLUSTER - 3 SERVER
• SSH aLLOW ON ALL OF THE SERVER
• PUBLIC KEY

One virtual network

four Subnets like the following:-

1. Public - Will have the WEB/API
2. The 1st Private will have - Queue , Worker , Elastic Search
3. Database Subnet the 2nd Private - database mysql
4. Cache subnet the 3rd private - KeyDB

Rules for Auto Scaling group.

• API and Web VMSS --> Scale out (Average) Percentage CPU > 70 / Increase count by 1 Scale in (Average) Percentage CPU <= 45/ Decrease count by 1

Auto Scaling Extenstion

• Extension API - healthRepairExtension (Microsoft.ManagedServices.ApplicationHealthLinux) 1.7 DependencyAgentLinux (Microsoft.Azure.Monitoring.DependencyAgent.DependencyAgentLinux) 9.10 MMAExtension (Microsoft.EnterpriseCloud.Monitoring.OmsAgentForLinux) 1.0

• Web DependencyAgentLinux (Microsoft.Azure.Monitoring.DependencyAgent.DependencyAgentLinux) 9.10 MMAExtension (Microsoft.EnterpriseCloud.Monitoring.OmsAgentForLinux) 1.0
