The document discusses refactoring a monolithic application architecture to a serverless one in 8 steps: 1) Reverse Conway's Maneuver by structuring teams around independent services, 2) Identify service boundaries, 3) Organize code into separate repositories for each service, 4) Choose deployment and CI/CD tools, 5) Keep functions simple and single-purpose, 6) Migrate features to new services incrementally, and 7) Maintain API compatibility during migration. The overall approach is to break the monolith into independent microservices that can be developed and deployed separately for improved scalability, resilience and development velocity.
Serverless technologies allow developers to go faster and do so much more with less. They allow businesses to innovate faster than ever possible before and the pay-per-use pricing model opens up a world of opportunities to improve cost efficiency. Cost optimization is no longer a guessing game, but a surgical operation that can target business areas with the most saving potential based on data. New business models based on pay-per-use will soon disrupt incumbents in established markets and create better value for customers. In this talk, we'll see how businesses around the world are using serverless technologies to drive their success and growth, and the lessons we can learn from them.
In this session, we'll talk about why Frontend Developers should care about serverless and how it gives frontend-focused teams the superpower to build scalable backend for their applications without all the traditional overhead of managing the infrastructure themselves.
Looking in from the outside, serverless seems so simple! And yet, many companies are struggling on their journey to serverless. In this webinar, AWS Serverless Hero Yan Cui highlights a number of common mistakes companies are making when they adopt serverless so you can avoid them.
Migrating existing monolith to serverless in 8 stepsYan Cui
Refactoring a monolith to serverless can be intimidating, but there are discrete steps that you can take to simplify the process. In this talk, AWS Serverless Hero Yan Cui outlines 8 steps to successfully refactor your monolith and highlight key decision points such as language and tooling choices.

Patterns and practices for building resilient serverless applicationsYan Cui
Lambda gives you multi-AZ out-of-the-box, but still, things can go wrong in production. There are region-wide outages, and performance degradation in services your function depends on can cause it to time out or error. And what if you're dealing with downstream systems that just aren't as scalable and can't handle the load you put on them? The bottom line is many things can go wrong and they often do at the worst of times. The goal of building resilient systems is not to prevent failures, but to build systems that can withstand these failures. In this talk, we will look at a number of practices and architectural patterns that can help you build more resilient serverless applications. Such as multi-region, active-active, employing DLQs and surge queues. We'll also see how we can use chaos experiments to help us identify failure modes before they manifest in production

FinDev as a business advantage in the post covid19 economyYan Cui
The impact COVID19 has had on consumer economy, ripples out to other service providers - analytics tools, etc because everyone is going to be squeezed. And the variable-cost (or pay-as-you-use) pricing model will be more appealing as companies tighten up their budgets for non-essential services/tools.

Raiders of the Fast Start: Frontend Performance Archeology
There are a lot of books, articles, and online tutorials out there with fantastic advice on how to make your websites performant. It all seems easy in theory, but applying best practices to real-world code is anything but straightforward. Diagnosing and fixing frontend performance issues on a large legacy codebase is like being an archaeologist excavating the remains of a lost civilization. You don’t know what you will find until you start digging!
Pick up your trowels and come along with Etsy’s Frontend Systems team as we become archaeologists digging into frontend performance on our large, legacy mobile codebase. I’ll share real-life lessons you can use to guide your own excavations into legacy code:
What tools and metrics we used to diagnose issues and track progress.
How we went beyond server-driven best practices to focus on the client.
Which fixes successfully increased conversion, and which didn’t.
Our work, like all good archaeology, went beyond artifacts and unearthed new insights into our culture. We at Etsy pride ourselves on our culture of performance, but, like all cultures, it needs to adapt and reinvent itself to account for changes to the landscape. Based on what we’ve learned, we are making the case for a new, organization-wide, frontend-focused performance culture that will solve the problems we face today.
Presented at NDC London, December 2014
Microservice architectures can lead to easier to change, more maintainable systems which can be more secure, performant and stable than previous designs. But what are the practical concerns associated with running more fine-grained systems, and what are the new things you’ll need to know if you want to embrace the power of smaller services without the new sources of complexity making your life a nightmare? This talk will delve deeper into the characteristics of well-behaved services, and will define some clear principles your services should follow. It will also discuss in more depth some of the challenges associated with managing and monitoring more complex distributed systems. We’ll discuss how you can design services to be more fault-tolerant, what technologies may exist in your own platform to get you started. We’ll end by giving some pointers as to when you should consider microservice architectures, and how you should go about introducing them in your own organisation.
Everyone loves fast sites. While "make your site faster" is a simple mantra, the actual steps to achieve this can be daunting. Fortunately, we know where to start: JavaScript. JavaScript consumes more CPU than loading, layout, and rendering combined. Byte-for-byte, JavaScript inflicts more delays on sites than any other resource, and yet the amount of JavaScript on sites continues to grow.
In this session you'll learn the latest techniques for measuring and improving the impact JavaScript on your site, including: using the User Timing Spec and Long Tasks API to track the CPU cost of JavaScript for real users, moving expensive JavaScript off the main thread, using code coverage tools to reduce your JavaScript, and understanding why defer is probably a better technique than async for loading JavaScript.

José M. Pérez Pérez | Better performance for component-based web apps | Codem...Codemotion
React, Vue.js and other component-based UI libraries are trendy these days. They improve developer ergonomics but can harm web performance with large bundles in SPAs. In this talk I will show how to use these libraries in combination with lazy-loading and code-splitting, so we get a performance boost on our sites.
Happy Browser, Happy User! NY Web Performance Meetup 9/20/19Katie Sylor-Miller
xPerformance is fundamentally, a UX concern. Sites that are slow to render or janky to interact with are a bad user experience. We strive to write performant code for our users, but users don’t directly interact with our code - it all happens through the medium of the browser.
The browser is the middleman between us and our users; therefore to make our users happy, we first have to make the browser happy. But how exactly do we do that?
In this talk, we’ll learn how browsers work under the hood: how they request, construct, and render a website. At each step along the way, we’ll cover what we can do as developers to make the browser’s job easier, and why those best practices work. You’ll leave with a solid understanding of how to write code that works *with* the browser, not against it, and ultimately improves your users’ experience.

"Our BDDs are broken!" Lean Agile Exchange 2020Seb Rose
Is the goal of your QA team to increase the number of automated tests? Are managers looking for tools that allow test-automation without the need for development skills? Are you using Given/When/Then phrasing to write automation tests?
In this session we’ll briefly define what BDD is, spend a bit longer describing what it isn’t, and look at several typical examples of what can go wrong if you use Cucumber when you’re not following a BDD approach.

Serverless in production, an experience report (Going Serverless, 28 Feb 2018)Domas Lasauskas
AWS Lambda has changed the way we deploy and run software, but this new serverless paradigm has created new challenges to old problems - how do you test a cloud-hosted function locally? How do you monitor them? What about logging and config management? And how do we start migrating from existing architectures?
In this talk Yan and Domas will discuss solutions to these challenges by drawing from their real-world experience running AWS Lambda in production and migrating an existing monolithic architecture for a social network to run on AWS Lambda.
Event: https://www.eventbrite.co.uk/e/going-serverless-tickets-41866816776
Join me for a retrospective look at how my team rewrote the core of a legacy application over six months and launched a well tested, stable product. In this session you'll learn how to work with an existing codebase without creating your own "legacy" code, by applying practices and tools such as identifying and using third party libraries, version control and code review, code quality measurements, BDD/TDD, and Continuous Integration.

Challenges of building a search engine like web rendering serviceGiacomo Zecchini
SMX Advanced Europe, June 2021 - With the advent of new technologies and the massive use of Javascript on the internet, search engines have started using Web Rendering Services to better understand the content of pages on the internet. What are the difficulties in building a WRS? Are tools we use every day replicating what search engines do? In this session, Giacomo will drive you on a discovery journey digging in some techy implementation details of a search engine like web rendering service building process, covering edge cases such as infinite scrolling, iframe, web component, and shadow DOM and how to approach them.
The case for web components as well as what they are and why they will forever transform the web as well as package managers and a little bit about headless web development.

At the heart of every event-driven architecture is a conduit for messages to flow through. AWS offers many services that can act as such conduit - EventBridge, SNS, SQS, Kinesis, DynamoDB streams, MSK, IOT Core and Amazon MQ just to name a few! These services have different characteristics and trade-offs around performance, scalability and cost. Picking the right service for your workload is not always easy. In this talk, let’s talk about how to pick the right messaging service to use in your event-driven architecture and play the game of trade-offs to your advantage.

Patterns and practices for building resilient serverless applications.pdfYan Cui
Lambda gives you multi-AZ out-of-the-box, but still, things can go wrong in production. There are region-wide outages, and performance degradation in services your function depends on can cause it to time out or error. And what if you're dealing with downstream systems that just aren't as scalable and can't handle the load you put on them? The bottom line is many things can go wrong and they often do at the worst of times. The goal of building resilient systems is not to prevent failures, but to build systems that can withstand these failures. In this talk, we will look at a number of practices and architectural patterns that can help you build more resilient serverless applications. Such as multi-region, active-active, employing DLQs and surge queues. We'll also see how we can use chaos experiments to help us identify failure modes before they manifest in production.
Serverless observability - a hero's perspectiveYan Cui
Yan Cui, an AWS Serverless Hero, will talk about the learnings from using serverless at scale.
He will cover the challenges for observability in serverless asynchronous workloads and the patterns to address those challenges, like using centralized logging, correlation IDs, tracing, lambda extensions.
How to ship customer value faster with step functionsYan Cui
Learn all about AWS Step Functions and how to use them to model business workflows and ship customer values quickly. In this session, we will talk about what is Step Functions, how to model business workflows as state machines, real-world case studies, and design patterns. By the end of this webinar, you should have a good idea of where Step Functions fit into your application and why you should use them (and why not!) to model workflows instead of building a custom solution yourself.
One of the key characteristics of serverless components is the pay-per-use pricing model. For example, with AWS Lambda, you don’t pay for the uptime of the underlying infrastructure but for the no. of invocations and how long your code actually runs for.
This important characteristic removes the need for many premature micro-optimizations as your cost is always tightly linked to usage and minimizes waste. As a result, many applications would run at a fraction of the cost if they were moved to serverless.
The pay-per-use pricing model also enables more accurate cost prediction and monitoring based on your application’s throughput. This gives rise to the notion of FinDev, where finance and development can intersect and allows optimization to be targeted to give the optimal return-on-invest on the engineering efforts.
And by building your application on serverless components, you can also leverage it as a business advantage and offer a more competitive, usage-based pricing to your customers. Which is going to be crucial at a time when businesses all around the world are affected by COVID and are looking for better efficiencies.
In this webinar, we will cover topics such as:
- How does the cost of serverless differ from serverful applications?
- How to predict and monitor cost in serverless applications?
- When should you optimize for cost?
- How can you leverage usage-based pricing as a business advantage?
Why your next serverless project should use AWS AppSyncYan Cui
In this webinar, Yan Cui and Lumigo Software Engineer Guy Moses will discuss some of the power of GraphQL and AppSync and why AppSync + Lambda + DynamoDB should be your stack of choice in 2021 and beyond!

You might have heard about chaos engineering in the context of Netflix and Amazon, and how they kill EC2 servers in production at random to verify that their systems can stay up in the face of infrastructure failures. But did you know that the same ideas can be applied to serverless applications? Yes, despite not having access to the underlying servers, we can still apply principles of chaos engineering to uncover failure modes in our system (and there are plenty!) so we can build a defence against them and make our serverless applications more robust and more resilient!
AWS has improved Lambda cold starts by leaps and bounds in the last year. But for performance-sensitive applications such as user-facing APIs, Lambda cold starts are still a thorn in one’s side, especially when working with languages such as Java and .Net Core.
In this webinar, we will dive into strategies for improving cold start latency and how to mitigate them altogether with Provisioned Concurrency, and how Lumigo helps you optimize your use of Provisioned Concurrency.
In this session, we will look at 10 common use cases for AWS Lambda such as REST APIs, WebSockets, IoT and building event-driven systems. We will also touch on some of the latest platform features such as Provisioned Concurrency, EFS integration and Lambda Destinations and when and where we should use them.

When a Lambda function times out, it’s one of the trickier problems to debug, especially if the function performs multiple IO calls. What was it doing when it timed out? And how do I identify these timeout errors quickly when Lambda lumps them together with other unhandled exceptions?
In this webinar, we will show you how to identify and debug timeout errors, and strategies for mitigating timeouts and degraded performance more gracefully when there are underlying issues.
One of the most common performance issues in serverless architectures is elevated latencies from external services, such as DynamoDB, ElasticSearch or Stripe. In this webinar, we will focus on how to monitor, detect and fix latency issues that arise when our Lambda functions need to talk to other services.

AWS has taken over the responsibilities of patching the OS and securing the underlying physical infrastructure that runs your serverless application, so what’s left for you to secure? Quite a bit it turns out.
The OWASP top 10 is as relevant to you as ever; DOS attacks are still a threat even if you can probably brute force your way through it as AWS auto-scales Lambda functions automatically; and did you know attackers can easily steal your AWS credentials via your application dependencies?
In addition to the traditional threats, serverless applications have more granular deployment units and therefore there are more things to configure and secure, and the tools and practices are still catching up with this fast-changing world.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
