Microsoft Windows Azure - Active Web Solutions A Software Engineering Company Help Save Lives Case Study

  1. 1. Windows Azure Customer Solution Case Study Developer Scales Search-and- Rescue Application to Help Save More Lives at Sea Overview “Our original architecture supported Country or Region: United Kingdom Industry: Professional services— 10,000 vessels, but the Windows Azure Software engineering platform enables us to support hundreds Customer Profile of thousands or even millions of vessels, Active Web Solutions (AWS), based in Ipswich, United without any capital expenses.” Kingdom, is a Microsoft® Gold Responding to high numbers of deaths at sea in Certified Partner that specializes in Web application the fishing industry, the Royal National Lifeboat and custom software Institution contracted Active Web Solutions (AWS) development. It has 35 employees. to create an automated sea-safety application. AWS developed a location-based service Business Situation AWS needed a way to scale its infrastructure, code-named GeoPoint, which successful sea-safety transmits position data to a centralized tracking application so that more lives could be saved, but wanted to and alerting system. AWS used GeoPoint to build avoid an expensive MOB Guardian, a search-and-rescue application development effort and costly infrastructure expansion. for fishing vessels. To extend GeoPoint to more scenarios, AWS migrated it to the Windows Azure™ Solution AWS migrated its application to platform. By hosting GeoPoint in the “cloud,” in the Windows Azure™ platform Microsoft® data centers, AWS attained massive and used the Service Bus and Access Control Service to scalability, richer functionality, and lower provide global communications infrastructure costs. AWS was able to quickly scalability. convert its application to a hosted service and Benefits avoid the expense of building and managing a • Massive scalability • New market opportunities data center. AWS also has the flexibility and • Lower infrastructure, scalability to offer GeoPoint to many more management costs • Faster time-to-market markets.

In early budget to rewrite the desktop 2008, Microsoft told AWS about the Windows Azure™ platform, adding that, when it was available, it would be perfect for MOB Guardian and other GeoPoint applications. The Windows Azure platform is a cloud-computing services platform hosted in Microsoft data centers that provides computing, storage, communications, and authentication services for creating scalable, pay-as-you-go Internet services. It includes Windows Azure, a cloud services operating system; Microsoft SQL Azure™ cloud database services; the Service Bus and Access

Accordingly, emergency alerts are no longer passed by satellite to physical servers at AWS, but rather are received by satellite using the Simple Mail Transfer Protocol (SMTP) and delivered to a number of message queues. Multiple service instances read from the queues, process the messages, and store the data in Windows Azure table storage. Emergency alarms are then relayed through the Service Bus to the end-user monitoring application in the search and rescue operations center. AWS administrators also use the Service Bus to manage Windows Azure services from a central Control Service components; and network management system online table and blob storage.
