Can I order some servers for my serverless please – London VMUG Presentation

I was super happy to be able to present again at the London VMUG today on some tech that’s going to make a huge impact, Serverless. Yes, its a dumb name, as dumb as cloud but basically refers to Functions as a Service. I went through what it is, covering the important points of event driven user defined functions spun up and down on demand. There’s no infrastructure to manage from the point of the developer, the provider does all the provisioning and scaling.

Here are the slides:

and continuing the summary of what I spoke about…

I went though some of the public cloud examples like Amazon Lambda, Azure Functions and Google Cloud Functions. There are also Kubernetes based options you can deploy yourself like Fission, Kubeless and Funktion as well as cross container platforms such as Apache OpenWhisk, IronFunctions and Funcatron. I spent time going through what events are, why they are so crticial to understanding serverless and gave some examples. How much it costs was covered, the differences between PaaS and containers. Listed the benefits and currently many disadvantages as its very new.

I also talked about how Ops is changing and doesn’t mean Ops goes away, just evolves. As it was a VMware user group I went through two connections to VMware, the kinds of things you could use serverless for to manage a VMware environment as well as the VMware cloud native story and using Photon Kubernetes as a Service as your private serverless hosting platform.

Functional billing was highlighted as probably the most important future benefit for serverless, being able to track the cost of every single function call you make which can very easily highlight the inefficiencies you have and the benefit of being now able to have business costings matching up to IT costings.

Looking into the future there’s lots that needs to evolve but perhaps this is the time to decide whether you skip PaaS and containers for some things that have event triggers and go straight to serverless?

JeffConf is also very soon so mentioned the London conference.

Thanks for having me London VMUG.
