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 Azure storage Elastic Search - Kibana Akamai Redis Monitoring Traffic Manager Load Balancer

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
