  1. June Meeting: Azure Infrastructure Automation with PowerShell

    June 04, 2015

    June 04, 2015

    Presenter: Mike McPhail

    While the cloud has enabled web applications and IT infrastructure at scale, it has also introduced a new set of challenges for both developers and IT professionals.  Common questions for both new and experienced adopters of cloud technology include: Where do I start?  How can I leverage cloud infrastructure to support my application?  How can I turn my infrastructure into code?  What is the business value for infrastructure as code?  From these challenges the emergence of DevOps roles has become significant within many IT organizations.  In this presentation we will examine the challenges faced with the adoption of the cloud from a DevOps perspective and provide real world solutions using PowerShell and Azure to create and maintain your cloud environment.

    Mike is a Senior Software Engineer at Meridium, where he is focused on supporting the cloud platform architecture.

  2. May Meeting: Data Modeling in NoSQL Databases

    May 07, 2015

    May 07, 2015

    Presenter: Brian Lanham

    Thinking about modeling your database has different implications in the NoSQL world. How do I handle relationships? How do I maintain referential integrity across subsystems? How do I use polyglot persistence to take maximum advantage of the right database for each use case? What about reporting? In this presentation we will discuss factors to consider when modeling data for NoSQL databases. We will use several different NoSQL databases including MongoDB (Document), Neo4j (Property Graph), and Redis (Key-Value) and C#.

  6. February meeting: Design Patterns in JavaScript

    February 05, 2015

    February 05, 2015


    Presented By: Aftab Ahmed

    JavaScript should be treated like any programming language when it comes to designing your code structure. We will look at several patterns that can be used to structure code in a way that’s more re-useable, more maintainable, and less susceptible to naming collisions. We will learn about patterns such as the Revealing Module and Revealing Prototype patterns and see how they can be used to convert function spaghetti code into structured code that encapsulates variables and functions. Then we will expand our discussion towards other common patterns, including function argument patterns, chaining, and observable properties.We will continue to take a look at patterns using timers, including asynchronous execution and recursive setTimeout. Finally we review module patterns, pub-sub patterns, and the promise pattern.

    Aftab is a Solutions Architect and Lead Software developer at CBIZ. His biggest interest is thinking about how abstract concepts come together to make a whole and can be taken apart without breaking them.
