3 Agenda What is DXC service? Deployment Failover Roadmap and self-care portal Q&A

4 What is DXC service?

5 DXC is cloud-based platform Runs on Microsoft Technology Consumption based pricing Managed services process Application availability

6 DXC service components Content Delivery Network (CDN) Azure WebApp Azure SQL database Azure Blob storage Azure Service Bus Find Content Delivery Network Azure SQL database Azure Blob storage Web App Service bus Find

7 Availability of underlying technology Component Availability Azure WebApp 99.95% Azure SQL 99.99% Azure Storage 99.99% Azure Service Bus 99.90% Find 99.90% CDN %

20 Deployment to integration Visual Studio Web deploy Octopus deploy FTP

21 Deployment without DB schema update Users Managed services 1. Copy code to a slot 2. Apply configuration transforms 3. Start application in the slot and verify 4. Swap the slot Web App New Web App Azure SQL database Slot New Code Configuration transofrm

22 Deployment with DB schema update 1. Replicate application s database 2. Switch application to the database copy a) Set application to read-only mode b) Stop replication c) Save point in time for restore Azure SQL database copy Users Web App Azure SQL database

23 Deployment with DB schema update Users Managed services 3. Copy code to a slot New Code 4. Apply configuration transforms 5. Start application in the slot and verify Web App Azure SQL database copy Slot Azure SQL database Configuration transofrm

24 Deployment with DB schema update 6. Swap the slot 7. Clean up Users Web App Slot New Web App Azure SQL database copy Azure SQL database

25 Failover

26 What do we mean by failover? Automatic No manual intervention needed Redundancy across different regions (Geofailover)

27 Why is this important? Delivers a even better SLA

28 DXC Architecture Content Delivery Network (CDN) End user traffic Web App Azure SQL database Service Bus Storage blob

29 Failover replication processes Code distribution through Epi deployment process Read-only mode Web App Web App Azure SQL database Service Bus Storage blob Azure SQL database Service Bus Storage blob SQL Database Active Geo-Replication Geo-Replicated storage Primary region Failover region

30 Failover mechanism End user traffic Content Delivery Network (CDN) Endpoint problem Read-only Write mode mode Web App Traffic Manager Continuous monitoring of endpoint health Web App Azure SQL database Service Bus Storage blob Azure SQL database Service Bus Storage blob Primary region Primary Failover region

31 Failover roadmap 1. Read-only mode in failover region (Early 2017) 2. Write-mode Web App in failover region 3. Switch primary/failover regions 4. Taking orders in Read-only mode Details subject to change
