How to use it?
- Use message queues as a transport between micro-services (e.g. RabbitMQ)
- Include Data Layer into your micro-services as add-on to create interconnections
BONUS: ETCD
- Use ETCD for dynamic and distributed configuration of the microservices infrastructure
- Use ETCD configuration to publish on and subscribe to message queues and exchanges
- Cloud ETCD available at www.compose.io/etcd

Data Layer is now Open Source

On-Demand Link: https://www.nginx.com/resources/webinars/dynamic-ssl-certificates/ About the webinar A key enhancement that we have introduced in NGINX Plus R18 is simplified provisioning of SSL/TLS certificates. More than 87% of websites now use SSL to encrypt communications over the Internet, with end-to-end encryption now the default deployment pattern for websites and applications. The explosion in certificates means some companies are managing many thousands of certificates in production environments. This calls for a more flexible approach to deploying and configuring certificates. In this webinar we discuss how to load SSL certificates dynamically, along with other configuration, security, and reliability challenges, with new features in NGINX Plus R18 and NGINX Open Source.

On-Deman Link: https://www.nginx.com/resources/webinars/need-service-mesh/ About the webinar: Service mesh is one of the hottest emerging technologies. Even though it’s a nascent technology, many vendors have already released their implementation. But do you really need a service mesh? Attend this webinar to learn about the levels of maturity on the journey to modernizing your apps using microservices, and the traffic management approaches best suited to each level. We’ll help you figure out if you really need a service mesh.

Moving to microservices brings promises of application modernization and agile applications development and deployment, but it also brings new challenges in managing these environments. Nowhere are these challenges more of an issue than with traffic management and security of microservices environments, especially in those which require high-volume, high-reliability, and high-security such as with financial services applications. In this session we’ll go through the basics of microservices traffic management challenges, North/South vs East/West traffic, managing each with ingress and service meshes, and some best practice guidelines with microservices traffic management.

Presented by Sigfrido Narvaez, Senior Solutions Architect, MongoDB Experience level: Introductory When it comes time to select database software for your project, there are a bewildering number of choices. How do you know if your project is a good fit for a relational database, or whether one of the many NoSQL options is a better choice? In this session you will learn when to use MongoDB and how to evaluate if MongoDB is a fit for your project. You will see how MongoDB's flexible document model is solving business problems in ways that were not previously possible, and how MongoDB's built-in features allow running at scale.

Should you use traditional REST APIs to bind services together? Or is it better to use a richer, more loosely-coupled protocol? This talk will dig into how we piece services together in event driven systems, how we use a distributed log (event hub) to create a central, persistent history of events and what benefits we achieve from doing so. Apache Kafka is a perfect match for building such an asynchronous, loosely-coupled event-driven backbone. Events trigger processing logic, which can be implemented in a more traditional as well as in a stream processing fashion. The talk will show the difference between a request-driven and event-driven communication and show when to use which. It highlights how the modern stream processing systems can be used to hold state both internally as well as in a database and how this state can be used to further increase independence of other services, the primary goal of a Microservices architecture.

The Bigger Picture: New Opportunities for the Modern Enterprise

Inside Analysis

Erik Kaju from Wise will give a talk “From 50 to 500 product engineers – data-driven approach to building impactful and efficient product teams”. Product engineering is data-driven. It is best to avoid personal opinions and back actions with data. Sharing data transparently and making it broadly accessible within the whole company helps to scale and build faster. Data-driven practices are useful beyond just product development. Over the years, we have been systematic and methodological in how we scale the company and track its health. This is a story of Wise growing from a regular-sized with 50 engineers to one with 500. While our headcount has grown tenfold, the speed of our releasing and ability to deliver complex projects has risen significantly. It is crucial for the scale-up to not slow down. And that is only possible with effective and unhampered teams. Join Erik for fresh insights that will inspire you to grow your teams, track their health and experiment with team metrics. (Language – English) Erik is Director of Engineering at Wise.

How does one process 200GB of streaming raw data, daily? Where dedicated servers and home-made solutions fail, BigQuery comes out the victor. We will talk about the big data architecture with over 110 million players total on record, how we managed to implement it, and how is it possible that we keep daily operational costs under $50. In the beginning we will explain what kinds of data sources a top-selling game has to integrate and analyze and how to pre-process the data to avoid ramping up costs in disaster scenarios. Part of the talk is also dedicated to all the components that are involved in the many transformations the data undergoes and we will show you how the output from the entire pipeline looks.

Alfresco Day Roma 2015: Digital Renaissance

In 1945 mathematician and physicist John von Neumann proposed an architecture of a computer that became vastly successful. Today all commercially successful computer designs follow the same set of principles. About 50 years later people have discovered that no single computer is sufficient to solve the biggest computational problems that mankind has, like indexing all the content published on the web. Today even small businesses have started to run into computational problems for which single-server systems become limiting. Unlike computers that are designed following clear guiding principles of the von Neumann architecture, designing computing clusters is still immature. Conventional view of cloud computing sees it as infrastructure-to-rent server instances or container boxes. When it comes to distributing computation, and scaling it to thousands of CPUs in milliseconds, there is no widely accepted architecture blueprint that outlines how it can be done. In this talk you will learn how distributed databases can serve as a solid foundation for massively-parallel and instantly-scalable distributed computing. We will also discuss leveraging NoSQL technologies, as it contributes to the architecture of a 'future computer.' We will also cover practical matters of large-scale distributed system design that are relevant to Big data and Cloud computing fields.

17. Demo Time

18. How to use it? - Use message queues as a transport between micro-services (e.g. RabbitMQ) - Include Data Layer into your micro-services as add-on to create interconnections BONUS: ETCD - Use ETCD for dynamic and distributed configuration of the microservices infrastructure - Use ETCD configuration to publish on and subscribe to message queues and exchanges - Cloud ETCD available at www.compose.io/etcd

19. Data Layer is now Open Source github.com/bdswiss/data-layer-rabbitmq License MIT
