Visualizing Serverless Cloud Systems

Cloud-native systems increasingly integrate services, or functions. Microservices and serverless patterns produce many small parts. See how effective visualization matters in solution design and implementation. Understand emergent visualization by example. See future directions around dynamic distributed system visualizations.

Danilo Poccia

Danilo works with startups and companies of any size to support their innovation. In his role as Principal Evangelist at Amazon Web Services, he leverages his experience to help people bring their ideas to life, focusing on serverless architectures and event-driven programming, and on the technical and business impact of machine learning and edge computing. He is the author of AWS Lambda in Action from Manning.

Taking Serverless to the Next Level

Moving to serverless brings more benefits if you can optimize the way you work. In this session, I share best practices on different areas, from infrastructure management to deployments, distributed architectures and the role of teams, focusing on people and processes that are at the core of software development. To support our findings, we’ll review customer case studies to see what they did, why, and which benefits they got most.

Rainer Stropek

Rainer Stropek is co-founder and CEO of the company software architects and has been serving this role since 2008. At software architects Rainer and his team are developing the award-winning SaaS time tracking solution “time cockpit”. Previously, Rainer founded and led two IT consulting firms that worked in the area of developing software solution based on the Microsoft technology stack. Rainer is recognized as an expert concerning .NET development, software architecture and databases. He has written numerous books and articles on C#, database development, Microsoft Azure, XAML, and web development. Additionally he regularly speaks at conferences, workshops and trainings in Europe and the US. In 2010 Rainer has become one of the first MVPs for the Microsoft Windows Azure platform. In 2015, Rainer also became a Microsoft Regional Director. 2016, Rainer also got the MVP award for Visual Studio and Developer Technologies.

Serverless Functions in the Azure Cloud

Ten years ago, Azure started with a strong focus on PaaS. No wonder that Serverless has also become super important in Microsoft’s cloud recently. Rainer Stropek has been using Azure since the days of the first technical previews. In this session, Rainer will introduce you to Azure Functions, one of the Serverless offerings in Azure. Instead of speaking about theory, Rainer will walk you through an end-to-end sample and use it to describe the inner workings of Azure Function’s programming model. No slides, just code, a session for Microservice developers who want to know how things work and how they can benefit from Azure in practice.

Dave Farley

Dave Farley is a thought-leader in the field of Continuous Delivery, DevOps and Software Development in general. He is co-author of the Jolt-award winning book 'Continuous Delivery' a regular conference speaker and blogger and one of the authors of the Reactive Manifesto.

Dave has been having fun with computers for over 35 years has worked on most types of software, from firmware, through tinkering with operating systems and device drivers, to writing games, and commercial applications of all shapes and sizes. He started working in large scale distributed systems more than 25 years ago, doing research into the development of loose-coupled, message-based systems - a forerunner of MicroService architectures.

Dave has a wide range of experience leading the development of complex software in teams, both large and small, in the UK and USA. Dave was an early adopter of agile development techniques, employing iterative development, continuous integration and significant levels of automated testing on commercial projects from the early 1990s.

Dave is the former Head of Software development at LMAX Ltd, home of the OSS Disruptor, a company that are well known for the excellence of their code and the exemplary nature of their development process.

Dave is now an independent software developer and consultant, and founder and director of Continuous Delivery Ltd.

Farley's Laws

We are not as smart as we think we are. Even us software developers!!

What we think of as reality isn't. When we think we are being rational, we are not. When we listen to experts and trust in their wisdom, we are fooling ourselves.

Meanwhile, software development is one of the more complex tasks that we mere mortals undertake. So what does it really take to overcome the limitations of our biology? How do we overcome our desire to jump to conclusions and guess at solutions?

This mildly humorous, entertaining talk explores some of the fallibilities inherent in our biology and addresses what it takes to solve genuinely complex problems in the face of our propensity to make wild guesses?

To put it another way, what do you need to understand to completely grasp how agile, lean development, DevOps and Continuous Delivery really work?

Mx. Kas Perch

Kas (they/them/their) is a developer 🥑 for CloudFlare. They’re also an author of two books about JS Robotics and a Twitch Affiliate streamer for code and hardware. They like serverless and all the discussions it brings, and playing with their 2 cats.

V8, Web Assembly, and Serverless-- a new way of thinking about edge computing

Let’s chat about our approach to serverless: how using the V8 engine and running user functions in isolates decreases overhead and eliminates cold starts. Let’s talk about how we leverage JS APIs and features like WebAssembly to allow you to run the code you need, where you need it.

Emrah Şamdan

Emrah Şamdan is the VP of Products at Thundra, a tool to provide serverless observability for AWS Lambda environments. With the development team, Emrah is obsessed with helping the serverless community with their debugging and monitoring effort both in production and during development. He is responsible for making trouble for the Thundra engineering team while finding solutions to ease the life of serverless teams.

From Development To Production: The Many Uses Of Serverless Observability

Serverless observability is commonly thought of as something useful while running your large serverless applications in production. But, did you know how it can be a valuable tool for dev and test as well? What about small or simple serverless applications? Or, if you’re just running a few simple functions? How helpful can observability really be? The answer: VERY!

Join us to learn:

- The basics of observability and why it’s useful for both known, predictable failures AND unknown, non-predictable failures
- Why observability is particularly useful for serverless applications
- How observability is valuable during development and while debugging
- How observability can be used to test your application
- How observability is useful in production with both small and large deployments

I will explain each topic but also, where appropriate show off how you can achieve this with live demos.

Erez Berkner

Erez is the CEO & co-founder of Lumigo, a startup focusing on simplifying serverless applications troubleshooting, where the entire backend is 100% serverless. Prior to founding Lumigo, Erez was the R&D director of cloud products at Check Point, heading the company’s cloud strategy & execution.

Troubleshooting Serverless applications, challenges, and best practices

Software does not always work as smoothly as we would like. In order to know if something went wrong, understand the root cause and fix the problem, we need to monitor our system and get alerts whenever issues pop up. There are many useful tools and practices for on-prem and EC2 based applications. As we adopt serverless architecture can we continue to use the same practices? Unfortunately, the answer is no.

In this session, we will discuss:

- Why is troubleshooting serverless based applications different
- Best practices for serverless monitoring
- Methods to efficiently troubleshoot serverless applications
