This document discusses how serverless computing can transform businesses by decreasing infrastructure, operational, and development costs while also decreasing time to market. It outlines the benefits of serverless such as reduced computing costs since customers only pay for resources used, reduced operational tasks and costs, and increased developer efficiency since they can focus on development rather than infrastructure. It also provides examples of serverless platforms from AWS, Azure, Google, and IBM and highlights Azure Functions capabilities such as its open source runtime and triggers/bindings that make working with data and services easier. The document argues that serverless computing can provide competitive advantages through faster iteration cycles and the ability to invest savings in the core business.

Transforming your Business with Serverless

2. Elephant in the Room
There are Servers… but we think about the Servers … Less

3. The Evolution To Serverless

4. Benefits of Serverless
DECREASED
INFRASTRUCTURE COSTS
DECREASED
OPERATIONAL COSTS
DECREASED
DEVELOPMENT COSTS
DECREASED
TIME TO MARKET

5. Infrastructure Savings
Don’t Pay to keep the lights on.
Only Pay for what you use. Drastically
reduced computing costs.
Eliminate costs associated with availability and
redundancy - don’t forget DR!
Costs savings over traditional elastic scaling
cloud services.

6. Operations Evolved
Standard operational activities such as administering, maintaining,
monitoring, patching, and securing servers are virtually eliminated.
Operations and their expertise are better aligned with business vs
systems.
Growth of Cross Functional teams as opposed to large teams of
dedicated operational resources. Operations + Developers = DevOps
Fewer traditional operations tasks but the tasks that remain are
absolutely critical. Serverless is reduced ops NOT NoOps

7. Developer Efficiency
Hyper focused on development tasks that contributed direct
business value (not infrastructure and plumbing).
Serverless frameworks often increase efficiency for common
tasks such as working with data and messaging.
Promotes the development of loosely couple systems and
micro-service concepts with less operational complexity.
Allow for more time on the user experience then backend
components.

8. Ensuring Success
• Cloud Native
• Don’t try to roll your own Serverless – use a cloud provider.
• Observability becomes critical so choice of APM Solution is also critical.
• Partner with the right cloud provider for your needs and organization.
• Establish your threshold for vendor lock in.
• Understand your latency requirements (cold starts)
• It’s not All-Or-None.
• Stay flexible!

9. The Market Leaders
AWS Lamda Azure Functions
IBM OpenWhiskGoogle Cloud Functions

10. Azure Functions - Differentiators
• 100% Open Source Function Runtime (Not Scaling Engine)
• Runs on Azure App Services Infrastructure (Consumption, App Service, Hybrid)
• Local Development with the Azure Functions CLI, advanced developer tooling w/ Visual Studio
and Visual Studio Code
• Event Based (Triggers) supporting http, queues (storage, servicebus), blobs, event hub, event
grid, etc
• Bindings – Super easy to work with data and services
• Language Support
 Javascript (Node.js)
 C#
 F#
 Java (Preview)
 Python (Preview)

11. Azure Function Example

12. Serverless = Competitive Advantage
• Iterate faster then your competition.
• Shorter and less expensive iterations.
• Measure iteration cycles in days and weeks and not months and years.
• Infrastructure, Operation, and Developer savings allow investments in
core business.
