The evolution of application platforms Microsoft Tech Summit FY17 5/21/2018 10:08 AM The evolution of application platforms On-Premises IaaS PaaS Serverless © 2016 Microsoft Corporation.

Before cloud What is the right size of servers for my business needs? What happens in case of server hardware failure? How do I deploy new code to my server? Which packages should be on my server? How can I increase server utilization? What media should I use to keep backup? How can I scale my app? What size of servers should I buy? Who monitors my App? How often should I backup my server? Who monitors my Servers? What storage I need to use? Which OS should I use? Who has physical access to my servers? Do I need secondary network connection? Are my server in a secure location? How many servers do I need? Do I need a UPS? What happens if the power goes out? How often should I patch my servers? How can I dynamically configure my app? It takes how long to provision a new server?

Then came IaaS—table stakes for digital business What is the right size of servers for my business needs? How can I increase server utilization? How many servers do I need? How can I scale my app? How often should I patch my servers? How do I deploy new code to my server? How often should I backup my server? Which OS should I use? Which packages should be on my server? Who monitors my App?

Then PaaS, critical for digital transformation What is the right size of “servers” for my business needs? How can I increase “server” utilization? How many “servers” do I need? How can I scale my app?

Serverless, the future platform for next gen apps How do I architect my app to become Serverless?

What is Serverless? Abstraction of servers Event-driven/ instant scale Micro-billing

Benefits of Serverless Manage apps, not servers Reduced DevOps Faster time to market

Serverless application platform components Development Local development Monitoring IDE support Integrated DevOps Visual Debug History Platform Functions Logic apps Event Grid Developer productivity Visual designer Manage all events in one place Triggers and Bindings 100+ connectors Near real-time delivery Flexible deployment options Functions orchestration Broad coverage Analytics Database Storage IoT Security & Access Control Intelligence

Serverless scenarios: anything that responds to events Timer-based processing Clean table Every 15 minutes Find and clean invalid data Real-time stream processing Millions of devices feed into Stream Analytics Store data in SQL DB Transform to structured data Mobile app backends Photo taken and WebHook called Stores in blob storage Produces scaled images Real-time bot messaging ... Chatbot sends response Message sent to Chatbot ? Cortana Analytics answers questions
