"Is serverless another passing technology fad or the new standard for application deployment in cloud computing?” It’s a good question and the topic of this presentation. We will discuss the current state of serverless computing and the many considerations before investing time and resources in serverless infrastructure. For many, data center priorities have shifted from absolute uptime and performance to ”move fast and break things” as espoused by Silicon Valley, a great mantra for those with limited legacy systems and a greenfield of new products. Though the question for many enterprises though is "How does serverless integrate into their existing data center strategy?" The discussion will not only explain the state of today’s growing serverless landscape but how you can integrate your existing data center with a cloud-native serverless architecture.

7. Serverless is the future (sort of)

8. TriggerMesh – Multicloud Serverless Management Platform
Continuous integration, continuous
deployment is going to change and that’s
where things like microservices, containers
are playing a massive role in the outer loop,
but one of the things that I think is going to
completely change how we think about logic
is serverless.
Serverless computation will fundamentally,
not only change the economics of what is
backing computing, but it’s going to be the
core of the future of distributed computing.
So this application paradigm shift of
intelligent cloud and intelligent edge is going
to be pervasively changing everything we do
inside of Windows, inside of Office 365,
inside of Azure and the rest of what you will
hear about in the next three days is about
unpacking this.
Satya Nadella
Keynote - Microsoft Build 2017 conference

9. TriggerMesh – Multicloud Serverless Management Platform
The torrid pace of adoption and innovation in
the serverless (Lambda) space has totally blown
us away,
In particular, Lambda, AWS’s main serverless
service, has “grown like crazy,” with hundreds of
thousands of active customers using it in the last
30 days. That’s 300%-plus year-over-year
growth.
“When we launched Lambda, the first serverless
compute service, it was a watershed moment,”
...large generations of customers will skip
instances and containers and go right to
serverless -- in fact, if Amazon.com were
starting today, it would go serverless.

10. Modern architecture is serverless

11. TriggerMesh – Multicloud Serverless Management Platform
What is serverless?
● Abstraction of backend infrastructure completely
● Execution environment for single purpose functions
● Hosted in public cloud or on-premise
● Serverless functions have a runtime in a stateless
container
○ E.g. Node.js, JavaScript, Go, Python, Java
● Event-driven startup triggers/instant scale out or in.
● Micro-billing instead of per-hour/month billing.

12. TriggerMesh – Multicloud Serverless Management Platform
Function-as-a-service (FaaS)
● FaaS delivers serverless computing
● Abstraction of backend infrastructure
● “Typically” leveraging Kubernetes

13. TriggerMesh – Multicloud Serverless Management Platform
Open source FaaS software
• Firecracker (Amazon)
• Fission (Platform 9)
• Fn (Oracle)
• Knative/Kubernetes (Google)
• Kubeless (VMware)
• OpenFaaS
• OpenWhisk (IBM)
• Serverless (Serverless Inc.)

14. TriggerMesh – Multicloud Serverless Management Platform
Backend-as-a-service (BaaS)
BaaS or Backend-as-a-Service refers to the infrastructure
components managed by a cloud provider.
Examples of BaaS:
• AWS S3
• AWS DynamoDB
• Azure Kubernetes Service (AKS)
• Google BigQuery

picture and uploads it
to object storage in
the cloud.
Various side photos

bucket on AWS
Resize images to thumbnails in a photo sharing service
S3 Event triggers an
Amazon Lambda
function.
Amazon Lambda
function resizes

Thumbnails are
written to another S3
bucket on AWS.
Thumbnails are

application from a
webserver and s3.

16. TriggerMesh – Multicloud Serverless Management Platform
Microservices
● Single purposes functions that
deliver accomplish a single task
● Can run on a server, container
or in a serverless infrastructure
● Microservices are typically
combined to deliver a cloud
native application via
presentation layer
Example of Microservices in a Storefront Application
Inventory

API

17. TriggerMesh – Multicloud Serverless Management Platform
Event-driven architecture (EDA)
● Design pattern around the production and reaction to
events
● Serverless functions are triggered by events
● Examples events:
○ A file uploaded to an S3 bucket
○ Inserts on a DynamoDB table
○ A message published to an SNS/PubSub topic
○ A CloudWatch alert

23. Where serverless breaks down

24. TriggerMesh – Multicloud Serverless Management Platform
Serverless gotchas
• Portability
• Automation / DevOps
• Cross-Cloud Communication

25. TriggerMesh – Multicloud Serverless Management Platform
The cold start problem
● Applications that haven't been used recently take
longer to startup and to handle the first request.
● Because serverless happens on use, there aren’t
dedicated instances ready to handle requests
● Solution: Run a function in a dedicated container/VM,
not serverless

Security risks
• Function Event-Data Injection
