Serverless computing allows you to build and run applications without the need for provisioning or managing servers. With serverless computing, you can build web, mobile, and IoT backends; run stream processing or big data workloads; run chatbots, and more. In this session, you’ll learn how to get started with serverless computing with AWS Lambda, which lets you run code without provisioning or managing servers. We’ll introduce you to the basics of building with Lambda and how you can benefit from features such as continuous scaling, built-in high availability, integrations with AWS and third-party apps, and subsecond metering pricing. We’ll also introduce you to the broader portfolio of AWS services that help you build serverless applications with Lambda, including Amazon API Gateway, Amazon DynamoDB, AWS Step Functions, and more.

Presentation from the developer track at I Love APIs London 2016 featuring Matt McClean, Amazon Web Services.
Developers have been jumping on the microservices bandwagon because of the obvious benefits of faster release cycles and innovation. However, microservices' downside is the increased server costs, operational costs, and performance costs. To reduce this complexity, Amazon Web Services created AWS Lambda - a compute platform that lets you build microservices with no provisioning and servers.
Matt McClean, Solution Architect from AWS, presents how to use AWS Lambda to build your microservices. He covers various architectural patterns and anti-patterns for using AWS Lambda.
Slides for a short presentation I gave on AWS Lambda, which "lets you run code without provisioning or managing servers". Lambda is to running code as Amazon S3 is to storing objects.
In this presentation we will discuss the evolution of IaaS, PaaS, CaaS, FaaS and how serverless computing is beneficial and what are the challenges we have faced so far
Serverless architectures allow you to build and run applications and services without having to manage infrastructure. With serverless architectures, your application still runs on servers, but all the server management is done by AWS. In this session, you will learn how to build applications and services using a serverless architecture. We will discuss how you can use AWS Lambda to run code for any type of application or backend service; Amazon DynamoDB to store application data with high scalability and redundancy; and Amazon API Gateway to create and manage secure API endpoints. We will run through a demo setting up a web application using this architecture, and we will discuss best practices and patterns used by our customers to run serverless applications.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Serverless Architectures in Modern
Applications

What Are Serverless Architectures?
They are not actually “serverless”...
Instead, serverless architectures remove the need for managing and handling
the servers where the application or services run.
Server management is handled by third parties for you!

4. The Benefits of Serverless
Serverless architectures have a lot of upside, not least of which is $$ saved.
No Server Maintenance Flexible Scaling
High Availability No Idle Capacity
Lambda Costs vs EC2: https://www.trek10.com/blog/lambda-cost/
5. The Current Shortcomings of Serverless
Serverless architectures are still new, and there are some growing pains.
Limited Execution
Duration
Statelessness
Limited Run-Time
Support
Cold Start Time
Logging & Debugging
6. When Does a Serverless
API Make Sense?
A serverless API is a good choice when you
want low server maintenance and low cost, with
a microservice application of moderate security,
that is not exceptionally sensitive to latency.
9. Route 53 is a DNS service that allows you to assign a
custom domain name to your web IP address.
This is an optional piece of the serverless configuration but
is commonly used.
API gateway assigns a default route to your API that can be
used without extra configuration.
We won’t be using this in our example today but it is an
important AWS service to know about.
Route 53
The Resource Router
10. AWS API Gateway is integral to designing a serverless web
API.
A series of configuration that handling API routing and
Lambda execution. Can be configured with a
swagger.yaml file.
The API Gateway performs a series of tasks:
- Authorizes incoming requests
- Routes incoming requests
- Formats responses into HTTP response format for
consumption by the client
- Handles errors responses from the Lambda functions
AWS API Gateway
The Gatekeeper/Router to the Microservices
11. Without access to your servers, you must secure your
resources through IAM policies both at the API Gateway
level and the Lambda level.
Many options to secure traffic including:
- JWT tokens
- IP Address
- Headers
- Cookies
API Gateway allows for custom, dynamically generated IAM
policies provided by custom authorizers.
AWS Identity Access Management (IAM)
The Security Around the Gateway
12. The basic component of Function-as-a-Service (F.a.a.S)
architecture.
Lambdas are the holding place and configuration for code
that will be executed in any one of many servers in the cloud.
Can be configured with unique IAM roles, environment
variables, memory, timeout, and more.
Currently support the following runtime environments :
- Node.js 6.10, Edge Node.js 4.3, Node.js 4.3
- C#
- Java 8
- Python 3.6 & 2.7
AWS Lambda Functions
The Serverless Functions Where the Code is Run
13. AWS DynamoDB is a No-SQL database that is commonly
paired with serverless frameworks because of it’s similar
benefits :
- Fast & Consistent Performance
- Highly Scalable
- Fully Managed
- Event Driven Programming (Integrates with Lambda
function to process DB events)
- Flexible
- Integrates with IAM for security and access control
We will not be using this in our example today but it is a
good technology to know about.
AWS DynamoDB
The Database Layer

Step 1: Download the Repository
This is going to be our client code, server code, and configuration. This is the jumping off point for
our serverless web API.
Repository URL
www.github.com/mschmidt712/serverless-counter
Repository Holder Username: mschmidt712
Repository Name: serverless-counter
16. 16
Step 2: Install Dependencies and Run UI
Here we will get the UI for our application up and running. This is going to be a simple web
application that allows the user to increment and decrement a counter.
Install Dependencies
yarn install or npm install
Run UI
npm start
17. 17
Step 3: Sign in to AWS Console
Immediately, the application is configured to run off of a pre-made serverless backend. Let’s start
the process of building our own to hook up to.
18. 18
Step 4: Create the Lambda Functions
To speed up the process of building the backend, the code for each lambda function is located in the
serverless-counter repository under the server folder
19. 19
Step 5: Create the API Gateway
The suggested route to configure the API gateway is using a swagger.yaml file. For this exercise
we will use the swaggerWithApiGatewayExtensions.yaml file to save some configuration time.
20. 20
Step 6: Configure the API Gateway
As you will see, the API Gateway requires a large amount of configuration. We’ll walk through that
now.
21. 21
Step 7: Deploy Your API
Once the configuration is done your API is ready to deploy!
22. 22
Step 8: Connect Your API to Your Counter
Now that your API is deployed, you will be given a unique url to access it. Copy/Paste this url into the
appConfig.json file in the UI and watch your API go live.
