We’ll cover….
Best practices of APIOps and DevOps
Why and how you go faster when you shift from monolithic to microservices
architecture and how that relates to your DevOps practice
You can try these practices today. Postman and Amazon API Gateway are
integrated, for example.

Monolithic Application vs Microservices
Build and deploy applications faster without straining additional resources
• Does everything
• Shared release pipeline
• Rigid scaling
• High impact of change
• Hard to adopt new technologies
• Does one thing
• Independent deployments
• Independent scaling
• Small impact of change
• Choice of technology

The biggest question we will get answered today is that
when we talk about serverless, quite often we get asked
“Can we follow the standard DevOps practices,
development lifecycle that we used in traditional
application development?”

Start right with three best practices
1. Treat your infrastructure the way you treat your code
2. Set up an automated integration and deployment pipeline
3. Build with monitoring and observability from day 1

API Security: Shared Responsibilities
1. If you don’t know what APIs you have how do you know
what to secure? Observability and governance
2. Consider how you keep your API secure without duplicate
and considering how your consumers will consume it

Most Valuable Lessons for Architects
Counterintuition produces architecture that considers how to handle trade offs
better and up front

Most Valuable Lessons for Developers
Coding the API isn’t just closing a ticket for sprint velocity. Now I have buy in to
better serve those needs of the API Consumer.

Most Valuable Lessons for Product Leaders
APIs, microservices, and even legacy SOA are not only technical concerns.
Just DevOps and APIs Products cannot just involve business or technical
stakeholders. In fact, you build on each others’ diverse strengths to build better
APIs given your constraints.

Takeaways
APIs as Product
Start with what the consumer wants/needs before jumping to the solution
Design 1st before you ever create a single line of code
Litmus Test
Can everyone upstream and downstream describe what the API does and why?
How painful is it to document?
KEY How delightful is it to consume with no internal knowledge?
