Lambda 101 – Serverless Business Logic

I’ll keep this post short and let the video do the talking. This twelve minute video will walk through three different Lambda examples and investigate the payloads of each. The goal is to get developers and system administrators comfortable with using Lambda to execute business logic!

See below for more details. Enjoy!

Why? My Obligatory First Post.

It is important for me to share with you who I am and why I am writing this.  I don’t expect this particular post to be the reason you come back, but hopefully it provides a foundation of trust and will give you an idea of the lens I am looking through.

Who am I?  I am Jon Leaman, a 27 year old Boston native.  This is my first real attempt to establish a personal brand online that embodies my values.  I am recently engaged, own a black lab named Argos, and love getting out on my motorcycle.  If you forced me to describe myself in a phrase, I would say I’m a prudent risk-taker.

Why am I writing?  To provide a platform for me to share ideas, insights, advice, and ask questions.  Ultimately, I will leverage this blog to foster personal development.  My topics will range from technical industry coverage (e.g. What’s the difference between VSAN vs ScaleIO?) to macro industry news/trends (e.g. Did the NSA kill America’s public cloud?), to how changes in IT affect the individual (e.g. What career advise and strategies are best to maximize your value in the long term?).  I kept my blog title vague to give me the freedom to cover a variety of topics, but more importantly to allow my blog to remain a relevant medium as I grow in my career.

Disclaimer: I’m currently working at EMC (3 years strong!).  This will undoubtedly affect my writing, but my writing is my own, and you can mark my word that all the content I produce is sincere.
