EVOLVING HOSTING OPTIONS The vast majority of existing applications live on on-premise or co-lo based infrastructure. As a result, any viable cloud offering must compliment and not compete with these existing investments. y Legac Past Prese Futur q 47% of New Apps are onprem q 88% of Sockets in corp. datacenter q 98% of large Orgs have some degree of virtualization q 20% of Orgs have Private Clouds q Majority of cloud growth is Iaa. S q Majority of new cloud apps are Paa. S q Most efficient model for cloud development nt e q ~16% of new Apps qualify as Saa. S q Business model, not hosting model. There are on-premise Saa. S apps.

What does it mean? Cloud Oriented Architecture

4 Cloud Oriented Design Principles Resiliency Elasticity Portability Efficiency

Design Principle #1 : Resiliency • Short Lived Transient Errors • Retry Logic • Fail Over • Long Lived Outages • Circuit Breaker Pattern • Knowledge is Everything • Platform seams are key • High availability configurations RECOMMENDED READING! – “Release It! Design and Deploy Production-Ready Software” by Michael T. Nygard

Design Principle #2 : ELASTICITY Compute “Unpredictable Bursting“ Average Usage Time Compute “Predictable Bursting“ Average Usage Time “Growing Fast“ Compute • Stateful design is poison • Async architectures are the antidote • Understand your app • Trigger points • Usage patterns • Capacity planning • Understand your platform • Auto scale? • Instrumentation data? Average Usage Time

Design Principle #3 : Portability • Running your workload where it needs to run • Data privacy and/or sovereignty • The Dreaded Vendor Lock-In • Proprietary features • Use Factory patterns • Avoid the “sticky factor”

Design Principle #4 : EFFICIENCY • To all my developer friends, “no more free lunch” • Cost controlling measures exist everywhere • Batching • Compression • Parking • You pay for the whole core not X % of it!

Choosing the Right hosting model Building Web Sites

Web Site Hosting Scenarios Web Sites (Paa. S ++) Virtual Machines (Iaa. S) Modern web apps Enterprise server applications Perfect if your app consists of client side markup and scripting, server side scripting and a database. Powerful capability to scale out and up as needed. Run your existing enterprise applications in the cloud, such as SQL Server, Share. Point Server or Active Directory. Continuous development Porting existing line of business apps Deploy directly from your source code repository, using Git or Team Foundation Service. Choose an image from the library or upload your own VHD. Popular open source apps Windows or Linux operating system Launch a professional looking site with a few clicks using apps like Word. Press, Joomla!, Drupal, Dot. Net. Nuke and Umbraco Support for Windows Server, along with community and commercial versions of Linux. Connect virtual machines with cloud services to take full advantage of Paa. S services.

Key Advantages of a Web Role • Vs. Azure Web Sites • You can access the machine • More options to configure the size • Manage versions using traditional lifecycle • Vs. Azure VMs • You get simplified deployment • You can optionally use OS servicing • You build for stateless scale by default!

What’s New? • VS 2013 + SDK 2. 2 • Simple login to Azure • Remote Debugger • Edit & Continue (IISExpress) • Auto-Scaling • Management Client (for Web Sites) • Flexible options • 32 bit mode • Classic ASP • Custom SSL

Some new SDK 2. 2 goodness and Auto-Scale baby! Demo

Designing and developing Databases

So much stays the same • Normalization of your data model … SAME • T-SQL across all versions is mostly the … SAME • Query performance and indexing and plan maintenance … SAME • Operational necessities … SAME • Permission management … SAME

But then comes the Rub • For mult-tenant • New Development Project • Known constraints • 150 GB • Throttling • SQL Auth Only • Required cluster index • Server Management • Feature delta • For Virtual Machines • I/O performance delta • Limited scale up options • No dedicated storage sub -system • HA + Azure HA • Best practice configurations (like Temp. DB) changes

What’s New? • SQL Database automated export options exist • SQL Database Premium Edition • Large Mem Virtual Machines • 56 GB RAM • Detailed Guidance on setup
