EXECUTIVE SUMMARY Creating ground breaking business apps is complex and time-consuming. It involves working across multiple operating systems and devices, scaling infrastructure, securely integrating data and access to multiple line of business systems, as well as automating business processes. Azure App Service is a one-of-a-kind cloud service that enables organizations to seamlessly integrate everything from mobile and web development with back-end systems in a radically simpler way. This allows organizations to deliver amazing apps significantly faster than using traditional development process. Organizations can stop worrying about the infrastructure and dealing with fragmented tools and instead focus on building great apps. This whitepaper is aimed at organizations IT decision makers looking to better understand benefits of using Azure App Service. Organization participating in this study, on average, experienced 26% reduction in development time which amounted to $15,000 savings per developed application. Traditional Total Web App Development 398 664 34 Our company culture is to move fast, Yet, our web app development used to take 6 to 8 months. With Azure App Service we have improved it to 3 months 26% Azure App Service 226 580 7 Hours per App - 200 400 600 800 1,000 1,200 App Requirements and Design Development Deployment and Maintenance For all managed web and mobile applications, average reduction in IT Admin effort was 60% which resulted in annual average savings of approximately $1,500 per application. Shorter development process means faster time to market and increased capacity to develop more apps, which drives IT and business partnership. 1
INTRODUCTION Developing apps one by one for multiple platforms is not scalable and not the best use of developers skills or time. To drive workforce productivity in a mobile-first world, employee and customer apps need to work on any device, no matter the platform, seamlessly integrate information from backend systems and work around business processes. Azure App Service is a solution that brings together the tools needed for building enterprise-ready apps around a common development, management and billing model. One can choose from a rich ecosystem of pre-built apps and API services and a unified set of enterprise capabilities including mobile backend services, turnkey connectivity to SaaS and enterprise systems, and workflow-based creation of business processes. Azure App Service frees developers to focus on delivering great business value instead of needing to worry about repetitive tasks such as stitching disparate data sources together and dealing with operational and compliance overhead. This unified approach lets organizations take full advantage of the service while meeting organization s goals for security, reliability, and scalability. In this study commissioned by Microsoft, several customers shared their data and experiences using Azure App Service for their web app development and management. The data was gathered, analyzed and the results were organized using common web app development process, as follows: Planning Requirements gathering Design and architecture Prototype or POC Development Code development Website/App integration Source code management Testing Deployment and Management Deploy to production Change management System administration 2
APPLICATION REQUIREMENTS GATHERING, DESIGN AND PROTOTYPING Developing a new website or web / mobile business application can be a lengthy process. Business requirements and/or customer needs can change often between starting and actually deploying the website / application. Azure App Service offers standardization and simplification through out-of-the box tools. Stages Traditional App Development Azure App Service Requirement Document and capture customer gathering requirements. Same as before. Length and time consuming process involving planning / Simplified and consistent planning / design - no Designs (architecture and technical) design for server/infra capacity; integration with existing apps and management tools; user right provisioning rules; business rules, disaster recovery, etc. purchase of hardware; prebuilt infrastructure; autoscale infrastructure; pre-built integrations with APIs, apps, back-end systems; etc. Prototype / POC Prototype building is detailed, time consuming and costly; often requiring building and provisioning of large test / POC environments. Pre-built staging, testing environments that can emulate actual production environments. Ready for POC. With Azure App Service we were able to put mobile app demo in front of the customer within a month! Current customers who participated in this study experienced significant effort reductions in designing and prototyping phases of web app development. On average, customers are seeing 43% time reduction which translates to $9,300 savings per newly developed web application.

Website / App Coding or Code Development Website / App Integration with Existing Systems Source Code Management or Versioning Testing Multiple dev tools to build websites/apps across devices and platforms. Even basic capabilities can take many man hours, with most applications built inconsistently, full of spaghetti code, different designs, etc. Integration is difficult since both software and hardware infrastructure of the organization need to be adapted to the app. Creating custom extensions require great deal of time and effort. None or external tools/environments for checking in code, dealing with versions, etc. Lot of time invested in governance and source code control. Integration testing in putting together all the code from different developers. Testing to make sure that feature functionality works. Performance and stress testing requires significant Monolithic app development across OS and devices. Integration with CMS (separation of text and code) minimizes recoding. Workflow based business process creation. Avoid repetitive tasks and manual coding. Wealth of pre-built apps in the Azure marketplace. Heterogeneous integration of Technologies (frontend, backend, CMS, weblogic...). Prebuilt APIs and app services providing integration with Azure AD, Azure SQL DB, Azure Storage, HDInsight, Power BI, O365, Dynamics CRM, and other Azure services and LOB apps.

Pre-built integration with AD ensures easy provisioning of role-based security. Automatic backup and restore capabilities. Auto scale capabilities. Deployment using Azure App Service is a breeze. It is on average 81% less time consuming than traditional web app development, based on experience of customer who participated in our study. This equates to savings of $1,100 per newly developed application. Deployment Traditional 34 Azure App Service 7 81% Hours per App - 5 10 15 20 25 30 35 40 Deploy to Production Change management and system administration for all web apps are also more efficient and free up IT resources. Average savings experienced by our study group were $700 per managed application per year. BUSINESS BENEFITS Creating web and mobile apps for any platform or device faster than ever before delivers cost savings but, more importantly, significant business benefits. 6
Participants of the study consistently brought up examples from the two key areas: shorter development time and SLA. Shorter development time means faster time to market and freed up capacity to build more apps. In fact, on average, study participants expected to undertake 10 more project year after switching to Azure App Service. More nimble IT allows for more business experimentation and speedier product development. All customers mentioned they had lofty SLA for uptime, and none of them could deliver it in the previous hosted environment. Azure uptime SLA of 99.95% fulfills the IT promise to the business. It also means less business loss due to downtime. CONCLUSION Microsoft Azure App Service provides large time and cost reduction in web and mobile app development and on-going app management. Development time savings could easily be translated in cost reductions or additional free development capacity. Azure App Service also empowers IT to deliver on expected SLA and build stronger partnerships with business in product development area. 7
