- Azure provides seamless scalability with low startup costs and 99.9% availability for customers. For ISVs like Ethos, Azure makes it easier to develop and maintain solutions while allowing one engineer to support more Azure-based solutions. - In performance tests, Azure had slightly slower response times for limited requests but steadier response times as requests increased compared to self-hosted solutions, which saw transaction rates drop off more quickly under higher loads. - Migrating to Azure solutions can maximize the value of existing software assets, improve security, and optimize costs compared to on-premise hosting. Ethos has experience helping customers with these Azure integration and optimization strategies.

6. Registered Users Operation Cost

7. Cost Insights Customer: Seamless and predictable scale up ability. Very low starting cost with 99.9% availability. Ethos(ISV): Easy to develop and maintain. Make more money from maintenance(one dedicated engineer can track more than 10 Azure-based solutions).

8. Performance Analysis

9. Performance Benchmark Hardware configuration: Legacy: CPU: 2.4G+2.4G; Memory: 1GB; Hard Drive: 60GB Azure Small Instance: CPU: 1.6GHz; Memory:1.75G; Hard Drive:225G

11. Performance Insights For very limited service requests, Azure-based solution takes slightly longer time to response than self-hosted solution. When more service requests come in, response time of self-hosted solution’s longest transaction will be longer. Meanwhile, response time of Azure-based solution’s longest transaction looks comparatively steady. When service requests increase rapidly, transaction rates of self-hosted solution drops down very fast, meanwhile transaction rates of Azure-based solution looks comparatively better.

19. Introduction-XLR8 Large Enterprise will benefit by reducing cost while improving business agility and keeping strategic control of data Small and Medium Enterprise benefit because isolated SaaS modules can now become fully integrated into enterprise software suites 3rd party/internal suppliers and independent software vendors (ISVs) will benefit as they get a direct distribution channel to customers/users

20. 21 A Unified, Social User Experience Create Stickiness All business processes can integrate into a dynamically generated module menu. This means enterprise users could access all business systems directly from the dashboard! The right column is a mashup of dynamically updated App Widgets. This provide a one-glance status update and overview The enterprise activity stream support traditional team-based collaboration, but users can also follow business objects and processes (documents, customer records, issues etc). Any business process can reach their user through posting to the stream.
