What we Will Cover What is Azure Our “Enterprise” Application to Migrate Migrating to Infrastructure as a Service Migrating to Platform as a Service Migrating your data tier Migrating your app tier

What is the Microsoft Cloud: Azure Global Physical Infrastructure servers / network / datacenters Infrastructure N Central US, S Central US, N Europe, W Europe, E Asia, SE Asia + 24 Edge CDN Locations Automated Managed Resources Elastic Usage Based Services computestoragenetworking virtual machines web sitescloud services SQL database noSQL database blob storageconnectvirtual network traffic manager Fabric

Option 1 – Infrastructure as a Service (IaaS) computestoragenetworking virtual machines web sitescloud services SQL database noSQL database blob storageconnectvirtual network traffic manager Fabric

IaaS Costs Per Month Egress Costs (outgoing) per 100GB in NA and Europe $18.05 per 100GB other locations Top package is over $55k a year Pre pay schemes can bring cost down by ~30% New High Memory options available (Sept 2013)

The IaaS performance story

Using IaaS – Pros and Cons Pros You can tell the CTO you have something in the cloud! Migration is easy Good resilience Fast provisioning Elastic resources No need to chat to the SAN guys ;-) Cons Not exactly “enterprise” class performance 100MB/Sec. Capped at 1,000 IOPS or 200MB/Sec Higher than on premise disk latency Limited Scale Up (8 cores) Your managing OS and binaries Not exactly “cheap” Sales guys will go straight to “TCO” and opex v capex discussions

Common Tools for Schema Migration Dacbac built into SSMS Migration Wizard (Codeplex) Generate TSQL Script SSDT (Visual Studio)

Common Tools for Data Migration BACPAC Deploy to Azure Wizard in SSMS BCPSSIS Third Party Tools

Suggested Approach For small databases use Migration Wizard For Medium databases use SSDT to validate Then BCP or bacpac For large databases use SSDT to validate Then BCP out, compress, transfer to cloud and bcp in A lot of benefit from making your on site version compatible with Azure Features Do try and go for parallel loading

Pricing and Sizes Size$/Month 0-100MB4.995 Up to 1GB GB3.996 per GB over GB45.95 for first 10GB per GB after that GB for 50GB per GB after that * Plus Egress Network traffic costs

WASD – The Performance story

Why is WASD slightly slower than IaaS? In IaaS we hit a wall with disk performance In WASD slightly earlier wall Caused by change in table design (latch contention)

Option 3 – Scalability Next Steps
