What is Serverless?
Medium/Twitter: @PaulDJohnston
Not FaaS*
*Not just FaaS
(although FaaS is important for most serverless implementations)
Medium/Twitter: @PaulDJohnston
Not -insert favourite FaaS platform
here-*
*Again not just FaaS
Medium/Twitter: @PaulDJohnston
Serverless is Inherently
Event Driven
And
Asynchronous*
*Consequence of FaaS and Queues

Medium/Twitter: @PaulDJohnston
Serverless is
Economic
not Technological
Medium/Twitter: @PaulDJohnston
So Serverless is about
Business
not
Technology*
*Consequence of CTO thinking
Medium/Twitter: @PaulDJohnston
So why does this matter
for an IT Department?
Medium/Twitter: @PaulDJohnston
1) Organisations don’t like uncertainty
Medium/Twitter: @PaulDJohnston
2) No such thing as a
“standard IT Department”
Medium/Twitter: @PaulDJohnston
So how does serverless get in?
Medium/Twitter: @PaulDJohnston
Serverless entry point 1:
Greenfield projects e.g. startups
Medium/Twitter: @PaulDJohnston
Serverless entry point 2:

  3. 3. Medium/Twitter: @PaulDJohnston Cloud, Data Centres and Energy
  4. 4. Medium/Twitter: @PaulDJohnston Future of Cloud and Climate Data Centres at least 2% of Global Carbon Emissions (bigger than aviation) Growth of Cloud/Data Centres likely to grow by at least 5x in next 7 years Efficiency is irrelevant due to Jevons Paradox - increased efficiency leads to increased demand Not just climate, but energy security - energy price rises Whitepaper written by Anne Currie and myself bit.ly/2024wp
  5. 5. Medium/Twitter: @PaulDJohnston Ethics Whitepaper - The State of Data Centre Energy Use in 2018
  6. 6. Medium/Twitter: @PaulDJohnston Background - Movivo CTO of Movivo in 2015 One of the first Serverless startups Android App + AWS Lambda By early 2017 was in 20+ countries with over 500,000 MAU AWS bill was ~$300/month (half data backup) Team of 2 serverless and 2 android developers in total
  7. 7. Medium/Twitter: @PaulDJohnston Background - AWS Senior Developer Advocate for Serverless 2017-18 Part of Lambda Product Team Responsible for speaking about Lambda, API Gateway, Step Functions, Serverless Application Repository, Lambda@Edge and other services Met and did workshops with many serverless customers
  8. 8. Medium/Twitter: @PaulDJohnston What is Serverless?
  9. 9. Medium/Twitter: @PaulDJohnston Not FaaS* *Not just FaaS (although FaaS is important for most serverless implementations)

  24. 24. Medium/Twitter: @PaulDJohnston Fewer lines of code…?
  25. 25. Medium/Twitter: @PaulDJohnston Fewer lines of executable code
  26. 26. Medium/Twitter: @PaulDJohnston So how do you manage it?
  27. 27. Medium/Twitter: @PaulDJohnston Managing Serverless: Some Questions How do you build a serverless team? Do you manage tasks differently? What are the key qualities of a serverless engineer?
  28. 28. Medium/Twitter: @PaulDJohnston Managing Serverless: Putting it another way What does it mean to use a Serverless approach ...for engineering ...and for the way you manage projects ...and teams?
  29. 29. Medium/Twitter: @PaulDJohnston Is going serverless like herding cats?
  30. 30. Medium/Twitter: @PaulDJohnston Answer? “It’s almost exactly the same [as normal software development]” - Ben Kehoe (Is this the end of my talk?)
  31. 31. Medium/Twitter: @PaulDJohnston Managing Serverless Development... ...is not the same as managing normal software projects. At least not completely the same (in my opinion) There are some special aspects
  32. 32. Medium/Twitter: @PaulDJohnston Because I’ve been a CTO... Perspective is different Pragmatist - keep it simple Strategist - business directs tech DON’T ASK ME TO CODE! (I can, but there are better people to do it)
  33. 33. Medium/Twitter: @PaulDJohnston Best Practices for Development
  34. 34. Medium/Twitter: @PaulDJohnston Best Practices No-one is ever 100% using best practices (but that’s the aim) These are some things you should be doing anyway…
  35. 35. Medium/Twitter: @PaulDJohnston Best Practices (ok… Good Practices) Daily Standups (can be virtual) Pair Programming Version Control CI/CD (they are not the same thing!) Testing Code Reviews etc… (not exhaustive)
  36. 36. Medium/Twitter: @PaulDJohnston Serverless = Cloud 2.0
  37. 37. Medium/Twitter: @PaulDJohnston Serverless = Cloud 2.0 THE SECOND COMING OF CLOUD
  38. 38. Medium/Twitter: @PaulDJohnston It’s about No Maintenance Automation Avoiding maintenance comes out of Automation… So Automate all the things And remember to maintain your automation (because nobody else will)
  39. 39. Medium/Twitter: @PaulDJohnston Serverless Best Practices
  40. 40. Medium/Twitter: @PaulDJohnston Serverless Best Practices Serverless Best Practices blog: https://bit.ly/serverlessbestpractices `
  41. 41. Medium/Twitter: @PaulDJohnston Each function should do only one thing Functions don’t call other functions Use as few libraries in your functions as possible (preferably zero) Avoid using connections based services e.g. RDBMS Serverless Best Practices One function per route (if using HTTP) Data flows not data lakes Learn to use messages and queues (async FTW) Just coding for scale is a mistake, you have to consider how it scales
  42. 42. Medium/Twitter: @PaulDJohnston What do these differences mean for ...Managing Teams? ...Individual Skillsets? Serverless Solutions
  43. 43. Medium/Twitter: @PaulDJohnston FaaS Each function is a high value unit Functions != features With FaaS/Serverless it’s Cloud Architecture not Software Architecture
  44. 44. Medium/Twitter: @PaulDJohnston FaaS: Skillsets Doer: Get it working Tester: Just TDD/BDD please Cloud First: Do as little as possible in code Under Engineer-er: Don’t make it complicated, make it work - nobody cares if it’s perfect as the quality impact is far less important than in a monolith
  45. 45. Medium/Twitter: @PaulDJohnston FaaS: Team Kanban: Tasks and tiny code units work very well (Scrums + Sprints less so) Discipline: Everyone on top of priorities Pair Programming: This seems to work really well here. Tiny Code bases seems to enhance this Feature Velocity: Good discipline/testing leads to high feature velocity (not code releases) Principled Architecture: If you have clear architecture principles, you can move incredibly fast
  46. 46. Medium/Twitter: @PaulDJohnston Events and Queues Different Architecture for most coming from Web - not request-response Asynchronous for most things by default Distributed systems Nuanced
  47. 47. Medium/Twitter: @PaulDJohnston Fast Learner: If new to this space All Rounder: Cannot do FaaS without this. Not “someone else’s job” Cloud First: Recognising what to use and when Communicator: Explaining event driven systems is hard. Documenting/explaining is key Events and Queues: Skillsets
  48. 48. Medium/Twitter: @PaulDJohnston Events and Queues: Team Principled Architecture: Build up principles of how to use what type of queue/event and when (push, pull, volume etc) Shared Knowledge: Communicate what you’re doing individually, but sharing architecture understanding is key. Have a process (see Principled Architecture) Constant Review: Often events and triggers already exist within a system. Recognise when to reuse and when to create new
  49. 49. Medium/Twitter: @PaulDJohnston Services Learn to use Services Much less likely to “Roll your own” (containers, open source) Already use many services so expand e.g. Analytics, Logging
  50. 50. Medium/Twitter: @PaulDJohnston Integrator: Learn to be an integrator of services. It’s key. Pragmatist: Recognise that the service is probably built and run by somebody who knows more about this than you do Cloud First: Recognising what to use and when Under Engineer-er: Simply let others do the heavy lifting Services: Skillsets
  51. 51. Medium/Twitter: @PaulDJohnston Pragmatic Approach: You can probably build 80% of services you use, but why would you? Document: Why do you use the service? What is missing? Support: Do not let one person be the point of contact for a service you use. Share the knowledge Security: Learn best practices over api keys and shared secrets (outside the repo is rule #1) Services: Team
  52. 52. Medium/Twitter: @PaulDJohnston Infrastructure as Code Most important aspect Almost impossible to do Serverless at even moderate scale without it Terraform, SAM, CloudFormation, Architect, stdlib, Serverless Framework, etc
  53. 53. Medium/Twitter: @PaulDJohnston Automater: Every engineer should be an automater as a matter of principle (bash, scripts, CI/CD etc). Every release should automate more All Rounder: Dev and Ops distinctions disappear. Everybody is everything. True (non-siloed) Engineering at that point Doer: Role << Responsibility Fast Learner: New services released almost daily. Need to be able to add in. Infrastructure as Code: Skillsets
  54. 54. Medium/Twitter: @PaulDJohnston Automation: Most important automation. Collaborative Deployment: Serverless tends towards much high number of deployments. Need great communication skills and understanding of canarying, blue/green deployment etc. Feature Velocity: It’s only a feature when it’s deployed. Code != Features. Uncoupled Logic Team Scale: You cannot achieve team scale without good Infrastructure as Code and CI/CD Infrastructure as Code: Team
  55. 55. Medium/Twitter: @PaulDJohnston Impact: Hiring Much broader skillset More “Engineering” than “Developing” Interviewing: Code Challenges? How do you interview? Primary skills are actually collaboration and ability to learn fast. Onboarding: ...is hard - Nordstrom. May be easier to hire juniors and upskill than hire seniors and reskill.
  56. 56. Medium/Twitter: @PaulDJohnston Impact: Upskilling Much broader skillsets Learning resources are fewer and relatively limited by use case - AWS, A Cloud Guru etc Ingrained thinking may be problematic More junior = better? Senior leadership still needed but more as mentors (feature velocity)
  57. 57. Medium/Twitter: @PaulDJohnston Impact: Remove Naysayers Naysayers can be time drains Remove or Repurpose Velocity of team is such that this can significantly decrease productivity
  58. 58. Medium/Twitter: @PaulDJohnston Impact: Roles << Responsibilities Jobs will change over time Within serverless engineering Dev and Ops merge, as does Sec and everything else “Cloud Native Engineers”
  59. 59. Medium/Twitter: @PaulDJohnston How does Serverless change the IT Department? Serverless is not the future, it’s already here Your IT Department will change
  60. 60. Medium/Twitter: @PaulDJohnston How does Serverless change the IT Department? Fewer 10x-ers, more mentors Increases communication Removes Silos - everyone is an Engineer (no Dev and Ops silos) Enforces Infrastructure as Code People have Responsibilities not Roles Emphasis on Automation and Deployment Much higher Feature Velocity Decreased reliance on code perfection
  61. 61. Medium/Twitter: @PaulDJohnston Serverless Engineer = Cloud Native Engineer (aka Pragmatic Hacker)
  62. 62. Medium/Twitter: @PaulDJohnston Serverless Team = Rapidly Collaborate + Automate + Document
  63. 63. Medium/Twitter: @PaulDJohnston Serverless Team = Slack + Automate + Document
