The Blink Mobility Platform uses Amazon Web Services to deliver an extremely scalable and robust deployment platform, using most aspects of the AWS to achieve superior results.
To allow us to allow optimized worldwide resolution for requests to AWS regions, we make use of Amazon’s Route 53, which delivers reliable, scalable DNS as well as prioritised round-robin DNS resolution.
The Elastic Compute Cloud allows the use of web service interfaces to launch instances as required.
We use AWS’ Elastic Load Balancers to determine when we need to add additional computing power. With the Elastic Compute Cloud’s (EC2). Using the AWS Elastic Load Balancer (ELB), we can route requests to the most appropriate EC2 instance based on load and proximity, as well as monitor such loads and initiate additional EC2 instances if required, often within minutes. The EC2 allows us to scale up or down as required, providing resizable compute capacity.
CloudWatch is used to monitor all AWS resources in real-time, including Amazon EC2 instances, Amazon EBS volumes, Elastic Load Balancers, and Amazon RDS DB instances. It allows us system-wide visibility into resource utilization, application performance, and operational health.
CloudFront is used to deliver static content.
Testing and Demonstration environments are kept on separate instances, so that they do not impact upon our Production Environment.
The Building Blocks
The Platform revolves around the Interaction. An Interaction defines a particular user request – it’s a verb. Interactions find, display, link, and fetch varied information from disparate information sources.
- Where is the nearest library?
- How many PCs are available?
- I need to report a pothole!
- When’s my plane leaving?
- What jobs do I have to do today?
With the BlinkMobile system you describe these verbs in an object we call, unsurprisingly, an Interaction. You don’t create application functionality, you don’t store any data, and you just encapsulate behaviour as micro applications.
These objects are the core of the BlinkMobile architecture. We call it our Interaction-oriented architecture – every aspect of functional delivery is in support of these User Interactions.
Using What’s Available
A service-oriented architecture abstracts business functionality into well-defined services whilst the Interaction-oriented architecture provides a device independent visualization of those services that can be delivered as a platform service.
If there aren’t services in neat APIs, Interactions can still deal with them. Interactions can deal with html, documents, spreadsheets, and databases etc.. An Interaction can access almost any information that can be accessed through the Internet.
