What is Scalable Magento stack?

• Web servers• Database servers• Cache servers• Media servers• Load balancers

What is Azure?

• cloud computing platform and infrastructure, created by Microsoft released in 2010

• 17+ Datacenters located in North America (6), South America (1), Asia(2+2), Europe (2), Japan (2), Australia(2)

• CDN nodes are located in 24 countries• Linux & Windows hosts• 99.95% availability SLA

What is Azure?

What is Azure?

Two admin portals

Magento stack on Azure

• 99.95% availability only if 2+ machines in a cloud service (availability set)

• 2 cloud services (Web & DB)• 2+ virtual machines for web• 2+ virtual machines for MySQL(master-slave

configuration)• Redis cache service (or servers)• Storage account for files (CIFS)• 1 virtual network

MySQL on Azure

• Available as a service or VM

• Service is provided by ClearDB

• Service is multi-tenant shared environment

• Service is geo-distributed + daily backups

Redis cache on Azure

• Available as a service• Needs 2+ VM if installed

on Linux

Cloud services

• Used to manage VM instances, load balancing and scaling

• Groups multiple VM instances under domain name [name].cloudapp.net

• Created automatically with a new VM instance

Cloud services

To group multiple VM instances under single cloud service choose existing service

Virtual networks

• Isolates virtual machines from internet

• Used for internal communications

Load balancing

• DNS level or network level• Network level is limited to

region• DNS level is cross-region• Traffic Manager for DNS

level balancing• Cloud service endpoints

for network level• Internal or internet facing

load balancing is available• UI is available only for

internet facing

Load balancing

Auto scaling

• Start and stop instances in cloud service automatically

• Scale by CPU usage

Process1. Create virtual network2. Create 2 Cloud services (Web, DB)3. Create VMs for DB & provision4. Create load balancer on DB port5. Create Redis cache service (new portal)6. Create File storage (CIFS*)7. Create VMs for Web8. Mount File storage as /media folder (cifs-utils)9. Provision Web servers10.Create availability sets

What is Chef?

• Configuration management tool

• Infrastructure-as-a-code• Chef server stores

recipes and configuration

• Chef client connects to store and updates infrastructure
