In the past 7 years, we have seen the rise of 7 key application architectures among others namely: SPAs Realtime Apps/APIs Hybrid Mobile Microservices Serverless IoT AI Node.js is very popular and performant and the hyper growth of modules and APIs proves the point…to an extent that there is a problem of too much choice and inconsistent quality. Application architectures however cannot afford the same clip of change, else nothing meaningful will ever get delivered. Simultaneously GoLang, Weave, R, Async Java, Swift, Scala et all are competing for the same mindshare. Architects have purists (monoglot) and/or best of breed (polyglot) approaches. Many of them view languages as transient and designs as perpetual. In this presentation, we will discuss standardization of design patterns across these 7 architectures and how node.js can be an integral part of them.

The natural tendency for application developers is to construct their code in a procedural, monolithic pattern. Veteran Developers know that this leads to error prone, unscalable, slow software – yet it is alarmingly prevalent. There have been several architectural patterns that have risen over the years which have attempted to mitigate this problem. We’ve heard of Service Oriented Architecture, Integration Patterns, and Event-Driven Systems, but the Reactive pattern has the best chance for success. In this talk I will discuss the tenants of the Reactive Pattern and the importance of moving away from Monolithic architectures into Reactive. We will examine Spring Integration and the Grails Async features (along with Netty and RabbitMQ) in order to show they can quickly and effectively help your application to become Reactive. Finally, I will argue that the JVM is the best foundation currently for this architecture – but that if we’re not careful, NodeJS may be the most popular.

The presentation addresses the challenges developers face with APIs, such as the diversity in authentication methods, SDKs, and the steep learning curve for each new API. The key proposition is to approach API interactions through an ORM-like abstraction, treating APIs as databases to simplify CRUD operations and action commands. The core idea revolves around treating everything as a message, leveraging microservices as modular, independent components that communicate through these messages. This approach enables a uniform way to interact with various APIs by encapsulating the complexities behind simple, standardized message formats. The example provided illustrates how updating a GitHub repository's description can be abstracted into a message, streamlining the process. This methodology promotes a component-based architecture where microservices, defined by their ability to handle specific message patterns, can be composed to achieve more complex functionalities. The presentation outlines how this model can be applied to the GitHub API, transforming traditional API calls into message-driven interactions, thereby achieving a higher level of abstraction and simplicity. The benefits of this approach include a unified interface for API calls, reduction in the reliance on multiple SDKs, and the facilitation of "pure" business logic that focuses on entity manipulation rather than the intricacies of API communication. The presentation concludes with practical considerations for implementation, such as handling logistics and edge cases, and offers resources for further exploration, emphasizing the philosophy of reducing unnecessary complexity in software design.

This presentation shares the journey of voxgig, a Software-as-a-Service platform for conference exhibitors, and its strategic decision to adopt microservices from the outset. The narrative unfolds with an exploration of how a small, remote team can build a significant platform, detailing a development timeline that spans from initial exploration to platform launch, all structured around microservices. The architecture of voxgig is dissected to reveal two pivotal tactics: Transport Independence and Pattern Matching, which collectively enable emergent design within the microservices ecosystem. These concepts are expanded to illustrate their role in facilitating service distribution, extension, specialization, and composition, laying the groundwork for a robust microservice architecture. Despite aspiring to an ideal microservice structure characterized by clean separation between client, application, and core data layers, practical challenges lead to a more organic coding approach, often necessitating later technical debt repayment. The evolution of voxgig's architecture culminates in a diverse ecosystem of 65 Node.js services, enriched by a detailed statistical analysis highlighting service size, age, quality, and the overarching message patterns that constitute the system's backbone. Key lessons emerge from voxgig's experience, underscoring the complexity of UX design, the importance of adhering to one's methodologies, and the value of investing time in a robust core system. Insights into operational efficiencies, such as service bundling for cost savings and the indispensability of a message REPL, are shared. The presentation concludes by emphasizing the critical role of components within the microservices framework, advocating for system-wide operability in a single process locally and the pragmatic use of synchronous messages for the majority of use cases, all while championing the concept of microservices as fundamental components of a scalable, agile architecture.

This presentation delves into the mathematical principles underpinning microservices, drawing inspiration from historical numeral systems to illustrate the significance of adopting efficient mental models in software architecture. By contrasting the complexities of Roman numerals with the streamlined Indian numerical system, the talk sets the stage for rethinking software design through an algebraic lens, where microservices are seen as algebraic functions transforming inputs to outputs, akin to CRUD operations. The core idea revolves around conceptualizing microservices as operations on messages, ensuring seamless service integration within complex systems through transport independence and pattern matching. This approach fosters a loosely coupled architecture where services communicate based on message content rather than direct identities, enhancing system flexibility and scalability. Practical examples, including the development of a Node.js module search engine, demonstrate the application of these concepts, showcasing the ease of system expansion and modification when services are designed to interact through a message-driven paradigm. The presentation concludes by underscoring the benefits of this methodology, such as increased system adaptability, easier management of technical debt, and a more granular approach to system evolution, advocating for a shift towards viewing microservices as integral components of a coherent and scalable system architecture.

In this thought-provoking session at mucon London 2018, the dialogue revolves around the foundational premise that microservices should be embraced from the inception of a project, irrespective of the organization's size, from startups to established enterprises. The discussion opens with a candid acknowledgment of the inherent challenges in software engineering across the board, probing into the reasons behind the perceived complexity of software development, our collective penchant for perfection, and the frequent overemphasis on process over product. The narrative then shifts to a more philosophical perspective, positioning microservices as the optimal intersection of psychological comfort and engineering pragmatism, conceptualized as units of quality, trust, and business logic encapsulation. This conceptual framework underpins a series of tactical recommendations, advocating for a message-centric approach to system design, where the delineation between monoliths, microservices, and serverless architectures blurs in favor of seamless communication and interoperability. Practical advice is offered on tackling the 'general case' in system design, encouraging the development of specialized services for outlier scenarios and promoting adaptability to change. However, this approach is not without its trade-offs, sparking a debate on the merits and pitfalls of repository strategies and the double-edged sword that is Kubernetes, juxtaposed against the benefits such as finely segmented technical debt, deferred decision-making, and the capacity to scale rapidly without extensive cross-team coordination. The session concludes on a reflective note, inviting attendees to explore further resources such as senecajs.org and "The Tao of Microservices", leaving the audience with a nuanced understanding of microservices as not just a technological choice, but a strategic framework for building resilient, adaptable, and business-aligned software ecosystems.

This presentation introduces a systematic approach to designing microservices using a visual language, beginning with the identification of requirements and distillation into messages that dictate service interactions. The methodology is illustrated through the process of developing a user registration system, breaking down the requirements into discrete messages like 'register-user' and 'confirm-email', which in turn inform the design of specific services handling registration and email confirmation. The discussion extends to the temporal and functional dynamics of microservice interactions, differentiating between synchronous and asynchronous, as well as consumed and observed messages, using a unique visual lexicon where hexagons represent microservices, solid and dashed lines denote synchronous and asynchronous communications, and arrow styles distinguish between message consumption and observation. The narrative further concretizes these concepts by outlining the design of a Node.js module search engine, showcasing how business requirements translate into a network of microservices handling search, indexing, and module detail presentation. The intricate web of service interactions is depicted through the visual language, demonstrating how services like 'web', 'search', 'npm', and 'github' collaborate through well-defined message patterns. By the conclusion, attendees are equipped with a versatile framework for microservice design, capable of transforming complex system requirements into clear, manageable service components, as exemplified by the 'nodezoo' search engine project. This methodological approach not only clarifies the architecture of microservices systems but also facilitates their scalability, maintainability, and evolution over time.

This presentation delves into the intricate balance of risks and rewards in adopting microservices architecture, drawing parallels between complex systems failures, like the Three Mile Island nuclear incident, and potential pitfalls in software systems. It underscores the inherent risk in systems composed of multiple dependent components, highlighting how increased component count amplifies failure likelihood, challenging the conventional wisdom that redundancy can safeguard against systemic flaws due to homogeneity in components. The discourse shifts to pragmatic strategies for managing deployment risks in microservices environments, advocating for frequent, low-impact deployments to mitigate the consequences of inevitable errors, as opposed to infrequent, high-stakes updates. The speaker presents microservices as a solution that simplifies deployments by isolating changes to individual components, thereby enhancing system reliability. The emphasis is placed on monitoring message flow rates as vital indicators of system health, with various microservice patterns like Actor, Subscriber, Chain, and Tree explored to illustrate message distribution dynamics. The presentation concludes with practical deployment strategies like Canary and Progressive Canary releases, along with the concept of "Bake" deployments to incrementally expose new features, using these methods as risk measurement tools within the continuous delivery pipeline. The talk encourages embracing measured, data-driven approaches and automation to navigate the complexities of microservice deployments effectively, ensuring that technology adheres to the unforgiving principles of reality over theoretical perfection.

Title: Rethinking Service Discovery in Microservices Architecture Description: This presentation delves into the microservices architectural pattern, emphasizing the importance of service discovery in a landscape where services operate under the illusion of being solitary entities in the system. The discussion begins with an overview of microservices — small, independent processes that communicate through messages, which collectively contribute to a robust component model facilitating rapid development, continuous delivery, and the mitigation of technical debt. The core of the talk addresses the complexities and unconventional programming models introduced by microservices, particularly focusing on the challenge of service-to-service discovery. Various strategies for service discovery are explored, including the use of configuration files, intelligent load balancing, service registries, DNS, and the necessity of a message bus. The concept of service discovery is then critically examined, proposing a paradigm shift towards pattern matching, where services interact based on message patterns rather than service identities. This approach advocates for transport independence, blind messaging, and a peer-to-peer model, where services maintain a local worldview, updated dynamically as services fluctuate. The presentation concludes by introducing the SWIM algorithm, an infection-style process group membership protocol designed for scalability and weak consistency, exemplified through a practical implementation in a Twitter clone built with 14 microservices.

This talk is an appeal to server-side JavaScript developers to make use of this time of change - Node.js is going to become the primary server-side platform for most developers. We can move forward from the old way of building web apps as large inter-locking co-dependent code bases. The Node.js module system has shown us the way. It's the first step. Now, we need to use the beauty of Node modules to help us build robust, scalable apps. This approach is called the Micro-Services Architecture. It's more than just having some services with HTTP end-points. It's about taking this to the extreme. Everything is a service, and no service is larger than 100 lines of code. We've been using this approach for most of our projects for the last 18 months and it works really well. We get to drop loads of project management ceremony. There will be some customer war stories.

Enterprise software teams are starting to understand and embrace the power of Node.js. They face a serious challenge: integrating Node.js into the legacy systems they maintain, and migrating these system over time into Node.js architectures. This talk is a pathfinder for those facing this task. As a community we must proactively engage with the Java and .Net communities, and create a deeper understanding of the "Node.js Way".

The micro-service architecture has changed the game for software development. It provides the first scalable, effective component model for software systems. By embracing the organic, dynamic and chaotic nature of micro-services, you can built fault-tolerant, scalable and reactive systms. But there is a dark side. Things can get out of control very quickly. As the number of micro-services, and messages and interactions between them grow, how do you keep control? How do you retain understanding of the system? How can you offer any commitments about its behaviour to your CEO? The answer is to embrace the complexity of the system, and recognize that it has emergent properties. Rather than auditing and tracking technical behaviour, measure the behaviour you care about, the business outcomes. This allows you to understand the effects of new deployments and failures at the right level.

The action of the next cyber saga takes place in the mystical lands of the Asia-Pacific region, where the main characters began their digital activities in the middle of 2021 and qualitatively strengthened it in 2022. Corporate espionage, document theft, audio recordings, and data leaks from messaging platforms were all a matter of one day for Dark Pink. Their geographical focus may have started in the Asia-Pacific region, but their ambitions knew no bounds, targeting a European government ministry in a bold move to expand their portfolio. Their victim profile was as diverse as a UN meeting, targeting military organizations, government agencies, and even a religious organization. Because discrimination is not a fashionable agenda. In the world of cybercrime, they serve as a reminder that sometimes the most serious threats come in the most unassuming packages with a pink bow.

In the thrilling conclusion to 2023, ransomware groups had a banner year, really outdoing themselves in the "make everyone's life miserable" department. LockBit 3.0 took gold in the hacking olympics, followed by the plucky upstarts Clop and ALPHV/BlackCat. Apparently, 48% of organizations were feeling left out and decided to get in on the cyber attack action. Business services won the "most likely to get digitally mugged" award, with education and retail nipping at their heels. Hackers expanded their repertoire beyond boring old encryption to the much more exciting world of extortion. The US, UK and Canada took top honors in the "countries most likely to pay up" category. Bitcoins were the currency of choice for discerning hackers, because who doesn't love untraceable money?
