The Future of Enterprise Applications is Serverless
The document discusses the evolution and benefits of serverless architecture within Amazon Web Services (AWS), highlighting the shift from monolithic systems to decoupled services managed by small teams. It emphasizes that serverless applications allow for greater agility, reduced overhead, and improved scalability without the need to manage servers. Key features such as AWS Lambda, API Gateway, and their applications in various domains like web development and data processing are also presented.

Editor's Notes
- #2 Welcome Serverless Track I am…
- #3 Few words… SA team lead Sanoma Developer, Admin…
- #4 Why are we here? New way of working – DevOps? Serverless technologies are here to stay Cornerstone in application design for many business critical applications https://secure.flickr.com/photos/mgifford/4525333972
- #5 Amazon founded 1994 Monolithic organization with separate development, operations, testing, dba:s. Monolithic product. Everything in Amazon.com back then – monolitchic application. From 2002 – massive transformation How we think about building applications and organizing teams. Decomposing Amazon.com and building new businesses AWS, Alexa, Kindle… with this model 1000s of microservices in amazon Two Pizza team concept 6-10 people. Some nbr of microservices – some part of overall product. S3 = 200 microservices. Allows it to scale & add features. trillions of objects and regularly peaks at millions of requests per second.
- #6 New developer comes in Flexible toolbox to build on. No need for team to worry about tooling This concept has lead us building services like S3, DynamoDB, Codepipeline
- #7 What still is team resp – traditional still lots of things. Like infrastructure management, alarms, runbooks, compliance…
- #8 Thinking - Can we shift more from the team to platform 2014 – introduced AWS Lambda
- #9 What does serverless mean for us? No servers to provision, manage or patch Scalability built in You shouldn’t pay for idle High availability built in. (Az:s)
- #10 For business… What our customers have told us: Agility Better focus on product & faster time to market Helps with scalability.
- #11 The center of our world, and what we believe the future will be, is AWS Lambda. Compute service – where you don’t need to think about the underlying infrastructure. (servers, containers, open sources Firecracker…)
- #12 Overview of serverless application Event Sources Function written in.. Services – anything. DB, rest-endpoint…
- #13 Regardless of programming language Handler - called on invoke Event - payload coming in. REST, Queue, DB change Context - runtime (req id, logging...)
- #14 You don't pay for Idle 100ms increments Free-tier Easy & Cheap to get started
- #15 Web apps Backends, mobile, iot Data processing Chatbots & Alexa IT Automation
- #16 REST APIs Scalability Security, DDoS, Auth Throttling, monetizaton
- #17 API GW overall Cloudfront Cache + monitoring Backends: Lambda, EC2, ECS, Any VPC
- #18 Typical web app pattern
- #19 Simple patterns: Data processing Messaging
- #20 Streaming Scheduled jobs
- #21 Keep orchestration out of code. Retries, exponential backoff. Parallel execution. Waiting and polling for results.
- #22 Adding languages & increasing memory (now 3GB) Lambda timeout 15min (prev 5min) SLA 99.95 In re:Invent – click…
- #23 In reinvent 2weeks ago Ruby launch Custom Runtimes allowing you to bring your own language. Our Ruby support is built on this. We are providing a C++ and Rust custom runtimes that you can use. They are available on GitHub partners providing runtimes such as PHP, Cobol
