CBRE, Inc.                                                                                     08/2013 – 11/2013

Senior Software Developer and Application Development Consultant

 

Overview: I was contracted to finish a project that was entirely Azure based and built upon a framework created by Microsoft Consulting Services (in order to acquire Microsoft's, HP's, and other large to small business's commercial real estate management and services).  I helped program Azure blob storage, design the blob storage partitioning strategy, unit test the Azure service bus for our publish subscribe and request reply restful API's. I worked on core Azure services listed below with unit and integration tests for all of our features and tasks.  I profiled our scaling needs to determine our auto-scale configuration.  I also worked on integration testing for our our restful API that consumed XML, created a common information model XML document, and returned the document to the customer with their optionally specified XSLT transformations.  I also helped design and develop the API mime standards according to business value.  Additionally I was on the Application Lifecycle Committee for CBRE to develop and deploy Team Foundation Server and Team Foundation Service using a Scrum methodology with some business specific customizations and best practices guidance to the entire company. At the end of my time, version 1.0 was released and we were told it was the new leading sales proposition.

 

Technologies:

C#, Microsoft Test, Team Foundation Service Scrum methodology, Continuous Integration with TFS build templates, ReSharper, Azure Storage Utilities, Altova XML Spy, Layered build environments for development, test, pre-production, and deployment.  Azure Websites, Azure Blob Storage, Azure Service Bus and Topics, Azure VPN, Azure SQL, Azure Backup, Azure Table Storage, Azure Auto scale, Azure Management Studio, Azure SSL services and certificates, Azure Affinity Groups, Azure Virtual Machines as well as testing Telerik's Azure Backup Services.

 

Azure Strategy and Use: 

I helped architect and implement our use of Azure.  It is important to note that we had an exclusive partnership with Microsoft to get training from their Azure experts as we were making a product that Microsoft would use to manage all of its commercial real estate holdings.  First we secured the endpoints of communication using SSL/TLS and we also used another layer of message encryption (SAML) so not only the transport layer but the message itself was encrypted.  Additionally each client of the service was issued a token using the Azure token provider that allowed the client to have secure communication with the service bus.  Finally we partitioned the blob storage for the client according to an asymmetric key exchange (public key encryption exchange of a hashed and salted symmetric key) while additionally offering OAUTH 2.0 authentication and potentially ADFS authentication.   

The key to the product working was the use of Azure's service bus technology where we employed relay messaging with queues, auto scaling worker roles that scaled as a function of queue size, and the two patterns of messaging we used, namely either publish - subscribe (using service bus topics and subscriptions model) or request-response (using the Service Bus queues model - in fact we used queues for both models but for the publish-subscribe methodology we additionally used topics and subscriptions).  We used Service Bus Relay Messaging to allow WCF services to be exposed and worker roles to handle the incoming messaging that was in the form of XML or JSON.  First after a client had securely created a portal for setting up an endpoint to send messages to they had to make the decision on the format to send the message in.  We had created an internal common information model that the client could either write to or they could use their existing message's format and define a translation (using XSLT) that upon sending and receiving of the message we used to make their message conform to.  We then stored the message in a secured, partitioned blob storage.   

Upon the storage of the message we defined an API using a RESTful format that allowed clients of the stored information to either use request-response patterned calls or publish-subscribe output formats that could be defined to go to a single listener or many listeners.  To ensure total backwards and forwards compatibility, the client also had the ability to define an exit RESTful endpoint where another XSLT transformation could be defined.  This ensured that the incoming message would be allowed to be sent in the format they were already using and include a transformation to our common information model and upon the sending of the message a transformation that allowed the message to be converted from our common information model to the recipients desired format.  Of course, if they decided not to change the incoming message we allowed them to send messages anyway and export them in the same format but many of our monitoring systems would not be able to be used so since all of the clients would be developing automation to use our service we constructed the XSLT transformations for them at a price. 

In addition to the use of these services we used Azure's virtual networking capabilities to add a layer of security for both the client if they requested it and for ourselves.  Upon the publishing of the common information model, the outward facing website the clients could use if they chose to (in fact, we had equivalent API's that allowed no need to actually use the client facing website at all but it was an option), and the RESTful API for defining transformations and endpoints we had created, we started allowing clients to use our service.  We indexed search results with Lucene.NET and allowed them to search over their defined partitions of applicable messages.  After launching the service in beta we were quickly and securely processing billions of messages using a limited testing budget of approximately $40,000 for the first three months of testing while securing revenues in the millions.  We increased then allowed contractual terms to dictate the SLA agreements and turned on scaling as a function of the contract for each client.  The end result was the lead topic for sales to clients for the largest commercial real estate company in the world.
