Dec 3, 2014Download as PPT, PDF0 likes629 views

by Rafał Legiędź - If you're one of those developers who are tied to a .NET platform but are willing to use JavaScript whenever possible? Or maybe you develop server-side applications in JavaScript and you would like to call infrastructure code written in .NET? During this session you will get to know how to deal with above scenarios by using Edge.js module, which allows you to run Node.js and .NET code in one process on Windows, MacOS, and Linux.

Serverless computing allows code to run without provisioning or managing servers. The document discusses serverless architectures using containers and functions as a service (FaaS). It explains that with serverless, infrastructure is dynamically provisioned to run functions in response to events, then shut down after, avoiding idle resources. Serverless combines backend as a service (BaaS) and FaaS. The document provides an example of building a serverless blog service using AWS Lambda and discusses benefits like autoscaling but also challenges like vendor lock-in and cold start latency.

Buzzwords: Microservices, containers and serverless - real life applications ...drnugent

Modern applications are moving away from the traditional request/response loop to more event-driven patterns. The concept of “serverless” computing is floated around when discussing microservices and modern architectural design patterns. But what is serverless, and how - if at all - is it different than microservices? We’re entering a world where developers won’t have to think about provisioning resources to run their code. While serverless computing sounds like nirvana, there’s an upfront investment in changing development and operational patterns to allow for such a level of automated orchestration. Meanwhile, innovative teams have embraced the use of microservices as a direct response to the costly and cumbersome monolithic methodologies of the past, but new questions have arisen around use cases, planning, and best practices for implementation. This talk explains why now is the dawn of the serverless age. It also discusses best practices and tools that are available to address the challenges of service-driven architectures head-on while deploying in a serverless environment.

Microfrontends architectures - Nick Balestra - Codemotion Amsterdam 2018Codemotion

While microservice architectures allowed teams to scale delivery of independently deployable services, most frontend layers are still run as monolithic applications. Similar to server-side applications, frontend layers often grow into large monoliths that are difficult to maintain and evolve. The idea behind microfrontends is to enable multiple teams to work seamlessly together by fostering end-to-end ownership of independently deployable UIs. During this session you'll learn how companies like OpenTable and Skyscanner rely on OpenComponents to deploy microfrontends architectures at scale.

Icinga Camp Amsterdam - Icinga DirectorIcinga

Icinga Director is a configuration management tool that allows for easy centralized configuration and deployment of monitoring configurations to Icinga nodes. It supports fully automated environments as well as point-and-click users.

Icinga Director aims to make monitoring configuration "just work" across dynamic infrastructures.

Microservices with Minimal APi and .NET 6Miguel Angel Teheran Garcia

Minimal APIs and microservices allow for building simple and scalable APIs and distributed systems. Minimal APIs reduce complexity by removing unnecessary overhead compared to traditional MVC solutions. They are easy to learn, develop, and maintain. Microservices follow an architecture that is cloud-oriented, with low coupling between independently deployable services. Together, minimal APIs and microservices provide approaches for building performant, scalable solutions.

Presentazione Codemotion LinkMe Srl

The document discusses the development of a crowd economy platform called Crowdcore using cloud computing and the MEAN stack. It describes how MEAN (MongoDB, Express, AngularJS, Node.js) provided scalability and flexibility. Modules were developed independently and integrated using AngularJS directives. The infrastructure was designed to be cloud-native for easy scaling and deployment. Key lessons learned were that the technology supports crowd economy models, MEAN is highly scalable and flexible, and cloud-native applications can manage cloud infrastructures.

- Docker is a platform for building, shipping and running applications. It allows applications to be quickly assembled from components and eliminates discrepancies between development and production environments. - Docker provides lightweight containers that allow applications to run in isolated environments called containers without running a full virtual machine. Containers are more portable and use resources more efficiently than virtual machines. - Docker Swarm allows grouping Docker hosts together into a cluster where containers can be deployed across multiple hosts. It provides features like service discovery, load balancing, failure recovery and rolling updates without a single point of failure.

Did you know that tech giants like Amazon, Netflix, Tumblr, PayPal, and Reddit use Node.js? Quite fascinating stats, right? No surprise, Node.js has gained wide popularity in the realms of technology. But why is all this Node.js buzz? To be honest, Node.js is popular because it uses JavaScript, which is the only choice to develop web apps in the browser. Not only this, but this technology also supports microservices architecture, which is powerful and suitable for organizations of any distinct size. With 61,000+ stars on GitHub, 7.49K votes on StackShare, and 2450 contributors, there is no shadow of a doubt that Node.js is the fastest-growing open-source project every developer is interested in learning.
