The Azure Journey – The Patterns
Dev / Test Single VM Build out Async appl Multi-VM Add Mission critical HA data on Multi-VM with Azure and SQL Storage How should we Build It…. Deploy it…..Maintain It?

The Journey Starts with Dev / Test

The Journey Starts with Dev / Test
What options do you have for Resiliency? Option 1: Basically Nothing Option 2: Azure Backup Single VM Instance Dev/Test Appl Logic Web database Azure storage Elastic Search - Kibana Akamai Redis Monitoring Traffic Manager Load Balancer

Protecting Azure IaaS with Azure Backup
Value proposition: Backup data & VMs wherever they reside – on-prem, Azure Leverage cloud as tape replacement for offsite backup and long term retention Minimize enterprise storage Eliminate branch office backup storage and infrastructure Centralized management from Azure Data Protection Manager Production Data Production Data

Configure your Azure Storage for Resiliency
Elastic Search - Kibana Akamai Redis Monitoring Traffic Manager Load Balancer Local Redundant Storage (LRS) Geo Redundant Storage (GRS) Build resiliency for Azure Storage

Elastic Search - Kibana Akamai Redis Traffic Manager Load Balancer LRS Azure storage Locally Redundant Storage (LRS) Stores 3 replicas of the data within a single zone (facility) in a single region Provides data durability for disk, node and rack failures

Elastic Search - Kibana Akamai Redis Traffic Manager Load Balancer GRS Geo Redundant Storage (GRS) Stores 6 replicas of the data across two regions (3 in each region) Provides additional durability to protect data against major regional natural disasters (e.g., tornado, hurricane, fire, etc, destroying a whole region) Azure storage
