Tear It Down, Build It Back Up: Empowering Developers with Amazon CloudFormationJames Andrew Vaughn

As a product grows, and the infrastructure becomes more complex, the Operations team traditionally shoulders the burden of maintaining this infrastructure while deploying code from Software Engineers. Code is sometimes given to Operations with little to no information regarding how it should run or what the criteria for successful deployment is. This is not due to lack of caring, Software Engineers often lack the context themselves to provide production deployment instructions. To Software Engineers, production can be like a walled off city, filled with pathways and rooms not to be explored, guarded by Operations. This presentation aims to provide a solution to this problem. We will address how the traditional separation of Operations and Software Engineers slows innovation, and redefine their relationship -- blending responsibilities. We will examine the transition of two real teams, an Operations team and Engineering team, from complete isolation, to closer environments through virtual machines, to one cloud environment shared by all and managed with CloudFormation.

REST services and IBM Domino/XWork - DanNotes 19-20. november 2014John Dalsgaard

Loose coupling of systems is key to future development! Why? Because it will allow us to change the "components" as we go along instead of creating monster big systems that are tied together using all sorts of different technologies. Webservices have been a way to obtain this over the last decade. More recently a special variant has become very popular, namely the JSON based REST service. Imagine you could extend your data out to the world outside your Domino environment? - in an easy way....! And imagine those data could easily be incorporated into other systems via standardized interfaces... Could that extend the value of your current systems further? Could this be a way to use new technologies to modernize your users' experience of working with your systems? Come and take away knowledge about how to open your Domino/XWork based systems up to the world outside using JSON based REST services. They are going to be key to future development in Domino/XWork - whether you want to use data in browser solutions (e.g. based on angular.js or ExtJS) or native mobile apps (built in whatever technology is best).

JDD 2016 - Jacek Bukowski - "Flying To Clouds" - Can It Be Easy?PROIDEA

Nowadays "cloud" and "microservice" terms are used all the time, even overused. Does any system must be the "microservices" deployed in the "cloud"? Definitely not! However once you see that your system may benefit from that architecture, the next question is how to get there - how to fly to the clouds? Spring was always about simplifying the complicated aspects of your enterprise system. Netflix went to microservice architecture long before this term even was created. Both are very much contributed to open source software. How can you benefit from joint forces of the both?

Let me introduce you: DOTSFrank van der Linden

DOTS (Domino OSGi Tasklet Service) allows developers to create tasklets outside of the Notes client to perform background tasks on the Domino server. Tasklets can be run on a schedule or manually and outperform Java agents. To use DOTS, it must be installed on the Domino server and Eclipse is used for development. Tasklets are developed as OSGi bundles and can be deployed to the server through a jar file or update site. Logging, progress monitoring, and annotations help developers code efficient tasklets. Multiple profiles allow isolating tasklets from each other.
