X : Serverless is all about services.
Me : Hmmm, Infrastructure as a Service is not about serverless. Neither are containers even if you provide it as a service. Think about consuming services but also mix in moving up the stack i.e. above "runtime" as a service ...
... as a "rough guide", if there is a runtime and you don't care / manage it then you're firmly into the world of serverless whether it's a data store / query service or a code execution environment.
There's also a perspective aspect here. Every decade or so, I build an awesome games machine ... liquid cooled, the works. How many games do I play? I don't ... I just like building machines and seeing how far I can push it. If I wanted to play games, I'd buy an xbox ...
... the same with business. If my focus is on the business and user needs then I'm going to be using serverless. If my focus is building amazing infrastructure and seeing how far I can push the kit, then I'll do that. The two are not the same.

I wouldn't joke about this, it's no longer beyond the realm of the possible. We shall see soon enough how concentrated the brexit vote is and how fragmented is remain. Unfortunately he has the charisma and the skills exist to make this possible. Don't be complacent - see Trump ->
i.e. the betting odds on Nigel becoming PM before 2025 have shortened to 3/1. That's rather alarming. I would advise taking the possibility as serious and preparing to counter any post EU election moves.
X : Do you think Corbyn should go and Labour adopt remain?
Me : Only if you want to increase the likelihood of Farage as PM. We will know better on Monday. A more effective path would be to explain to the "Anyone but Corbyn" crowd that what they're promoting is Farage as PM.

Oh my, Andrea Leadsom MP "It is with great regret and a heavy heart that I have decided to resign from the Government" ->
I might strongly, even vehemently, disagree with a person's policies but I do have respect for the public service they have provided. I do think it's time for May to stand down but I recognise the effort and attempt to find some form of compromise on brexit. Alas, not this path.
My future concern is now the possibility of "Farage as PM". Not because of who he is but rather the unknown of what comes with him. A populist party quickly generated can hide all sorts of views and unknowns within it. Storming EU elections without even a manifesto is ... well.

Questioning contributions, milkshakes and accusations around Farage finances ... are people deliberately trying to get the Brexit party to top 50% of the vote?
Reading some of the reactions, counter responses, lack of real discussion on any positive manifesto addressing current concerns .... oh dear. Are we really doing this? Prime Minister Farage? Seriously? Just let him hijack the newscycle? OODA anyone? Trump learned how to do this.
Oh gosh, this is horrifying. Can we please get Dominic Cummings to do a high speed "Odyssean" education on our political leaders so they don't mess this up. Or are we really going to amateur hour our way to Farage as PM?

The serverless shift

* From Code to Configuration
* From High LoC towards Low LoC (preferably zero)
* From Building Services to Consuming Services
* From Owning Workloads to Disowning Workloads
From Code to Configuration

Configuration is a form of "code", but is not necessarily programming. It defines the resources and services used and how they are combined for an application. The code is the ***unique business logic*** required for the application.
From High LoC to Low LoC (preferably zero)

Today's code is tomorrow's technical debt. Code is always a liability at some point in the future. Limiting this future liability is a good thing. Working to reduce this liability from the beginning is simply good practice.

"Serverless scaling" in this context means it can scale from zero to *concurrency limit*. That's fine... sort of. But to be truly #serverless you need..

... rapid cold starts

At present, Cloud Run cold starts are too long (unless I'm missing something) to be truly serverless
Yes, it depends on the underlying container here and yes the developer is responsible for that but even the "Hello World" takes too long for me (well over a second).

In the Lambda world it is in the few hundreds of ms for a well written usable function (even over API Gateway).
Yes I'm holding it to a higher standard. It doesn't mean it's not usable though. I think it has real promise. Lots of opportunity to build some amazing solutions with it.

Things you should not do: dump existing containers into it ... KNOW YOUR TOOLS!

1/ Twead incoming...
2/ I have some #serverless localhost v. cloud Dev n' Testing thoughts. As a teaser:
3/ Disclaimer: not everyone, not all the time, not always possible, hyperbolic by intent. But I think it should be the default position.

#serverless advocates - we are doing something wrong. I have been putting this off for a long time but I really think it is important and has to be said. Warning: LONG thread.
The trigger for this thread was a talk I gave at #DevOpsDays Edinburgh. It wasn't the talk per-say, but the whole conference experience (which was awesome, but that's a topic for another thread).
Here I am, with around 200 people who really care about the DevOps culture and practices - and so little of them has any experience with serverless tech.

THREAD:

So, let's have a quick chat about CI/CD and #serverless.

This will be more "overview" than in depth (it's twitter after all)
CI and CD* are not the same thing

*and there are 2 types of CD
CI is Continous Integration

When multiple developers are working on one project, at some point they have to come together and combine their efforts...

...therefore Integration

And that happens continuously over a project

For me a serverless (S-) architecture is much more than a event-driven function as a service (FaaS)...

(Thread)
#serverless #faas #architectures #thread #lambda #fastMovingTeams #ownership #devops
A S- architecture is an abstraction on top of a (potentially very complex) infrastructure, so that devs can focus on building great features and products and run their code in production without focusing on boring configuration and scalability.
This doesn't mean there are no servers and there is no care for infrastructure: quite the opposite indeed.
