if
software is eating the world
then
serverless is eating software

the same way WiFi is wireless…
#LonVMUG@julian_wood7
So, what is Serverless?
Event Driven Functions as a Service
#LonVMUG@julian_wood
What is Serverless?
8
user defined functions
event triggered
spun up and down on demand
fully managed compute
upload code, provider does rest
transparent scaling, provider managed
no VMs/containers to manage
pay per code execution
#LonVMUG@julian_wood9
Stateless Event Driven Functions as a Service

#LonVMUG@julian_wood10
Amazon Lambda Azure Functions Google Cloud Functions
kubernetes based
Funktion
cross container platform

FaaS & BaaS
13
(mobile) Backend as a Service
back end services
not backend logic
Amazon API Gateway
Google Firebase

Events
15
HTTP requests
file changes
web hooks
time scheduled tasks
database record update
events stream
message bus
new code commit to GitHub
IoT sensor reading
#LonVMUG@julian_wood
File Processing
16
#LonVMUG@julian_wood
execute code every 15 minutes that cleans up a database table
Timer processing
17

#LonVMUG@julian_wood
Webhook
18
https://azure.microsoft.com/en-us/services/functions/
webHook URL, saves user data, decides what data to display
#LonVMUG@julian_wood
sensors in tractor detects need for a spare part and automatically place order

Fission – http request
22
#LonVMUG@julian_wood
Languages
23
Azure Functions JavaScript, C#, F#, Python, PHP, Bash, Batch,PowerShell
AWS Lambda Node.js, Python, Java 8, C# (.NET Core)
Google Cloud Functions Node.js
Apache OpenWhisk Node.js, Swift, Python, container
Platform9 Fission Node.js, Python, container
#LonVMUG@julian_wood
Stateless
24
ephemeral
no local state
write state to external disk / database
#LonVMUG@julian_wood
£ How Much?
25
requests
+ duration (rounded up to 100 ms)
x configured upper memory limit
Free: ☺
1 or 2 million requests + 400,000 Gb-s
#LonVMUG@julian_wood
FaaS vs. PaaS
26
FaaS:
scaling for individual requests
bring whole app up and down for each request
PaaS:
long running
tooling and maturity
caching
state
#LonVMUG@julian_wood
FaaS vs. Containers
27
FaaS:
event driven
container abstraction
Containers:
general purpose IaaS
tooling
DIY languages
portability
#LonVMUG@julian_wood
Benefits
28
Cost: development, operational, scaling
Easier no autoscaling,
Management: zero system administration
Productivity: pure function code,
no HTTP sessions, authentication,
back-end glue
#LonVMUG@julian_wood
Disadvantages
29
Performance:
Security:
Resources:
shared time limit (not GCP)
disk memory
warm up concurrent executions
inconsistent
spin up time especially JVMs
no multi-tenancy
noisy neighbour
#LonVMUG@julian_wood
Disadvantages
30
Configuration:
Ops:
limited languages discovery
environment variables stateless
testing monitoring
debugging external systems
versioning blue/green
#LonVMUG@julian_wood
Disadvantages
31
no roadmap
vendor lock-in
outsourced control = downtime?
portable code, not portable ops
isolated events/bus
integrated services
#LonVMUG@julian_wood
AWS Integrated Services
32
#LonVMUG@julian_wood
Azure Integrated Services
33
#LonVMUG@julian_wood
FaaS at the Edge
34
Azure Stack + Azure Function
Embedded Lambda on connected devices
AWS Greengrass Edge
AWS Snowball Edge
#LonVMUG@julian_wood
FaaS & NoOps - look no OS! ☺
35
“Ops” = way more than server administration
FaaS = outsourcing sysadmin
monitoring, architectural scaling,
security, debugging, networking
FaaS 4 Ops : tagging, lifecycle, security, compliance
#LonVMUG@julian_wood
VM Management use cases?
36
PowerCLI
snapshots
VM creation / deletion
NSX firewall rules
tagging
SRM
log analysis
security events
#LonVMUG@julian_wood
VMware Infrastructure
37
close to other stuff
VMware on AWS
deploy/scale Cloud Foundation
IBM BlueMix (Softlayer) + Watson
vSphere Integrated Containers
Photon
Kubernetes as a Service
Ops + DevOps
#LonVMUG@julian_wood
Make Money
38
sell your functions
Amazon API gateway -> API marketplace -> Lambda
#LonVMUG@julian_wood
The Amazing Functional Billing
39
functional granulatory
visibility
focus dev time
reduce waste & duplication
prove insource/outsource
marketplace service discovery
cheap to play
correlate business cost to IT cost
#LonVMUG@julian_wood
What’s coming/needed
40
better tools, monitoring, logging etc.
Service Fabric
AWS Step Functions Azure Logic Apps
Vendor abstraction
Serverless Framework Lambada Framework
#LonVMUG@julian_wood41
if you have event triggers…..
do you skip PaaS?
do you skip containers?
