Why Cloud Ides Are the Future? Containing your development – why Cloud IDEs are the future? Steve Poole @spoole167 Andy Watson @AndyRWatson About me Steve Poole Andy Watson @spoole167 @AndyRWatson Developer advocate for Developer advocate for Runtimes Eclipse CodeWind Cloud: it’s what we always wanted Today, our Cloud story is really a container story Containers are giving us new opportunities As long as the answer is “container” We’re all set on a future with containers Containers offer immutability and repeatability Enabling new architectures The idea was to swap larger long running systems With many, many fast starting , short lived ones Initially we thought containers made it easy.. FROM jetty RUN apt-get update COPY my.war /webapps Store code Compile and Build the image Push the image in Git Test locally locally It’s not turned out that way It’s tough being a container developer #worksfineonjdk9 #workslikeheavenonjdk11 What does the dev environment look like? Add in the build cycle #worksfineonjdk9 #workslikeheavenonjdk11 Add IDEs, tests, test data and quality tools.. #worksfineonjdk9 #workslikeheavenonjdk11 Wait, there’s more… #worksfineonjdk9 #workslikeheavenonjdk11 The CI/CD Pipeline Now add more frameworks and languages Add containers and clouds… In a container in your desktop In a container in your CI system Your development Lifecycle Runs on your desk To produce an image … Doesn’t look very “immutable” does it? In a container in your desktop In a container in your CI system Your development Lifecycle Runs on your desk To produce an image … Do these match? A common tale your Your local your CI system production environment system What you build here your Your local your CI system production environment system Doesn’t match what builds here your Your local your CI system production environment system Or what runs here your Your local your CI system production environment system And… What runs in production your Your local your CI system production environment system Is difficult to test here your Your local your CI system production environment system And almost impossible to test here your Your local your CI system production environment system And where we thought we’d have one architecture… Traditional Monolith in a box microservice Serverless / eventing function function APP APP APP APP µFrame FRAME FRAME FRAMEWORK work FRAMEWORK WORK WORK Java / µF µF APP APP JVM APP SERVER APP SERVER SERVER SERVER Java / Java / Java / JVM Java / JVM JVM JVM µF µF OS OS OS HARDWARE HARDWARE HARDWARE We’re using them all To deliver we have multiple stages of verification What the IDE What the full build What the full build What the dev CI thinks thinks in the container full build thinks thinks 1 What the prod CI What the dev CI What actually What the prod CI container build container build happened full build thinks thinks thinks Because we can’t be certain a developer's action won’t break the production system Cloud Computing is not perfect - yet But who cares about a little rain?

Umm…. Enough tools for you? Building, testing and deploying is changing too In the cloud a single server You don’t want is too high a to be left risk hanging around – waiting for the CI system to come back Containers are changing everything about how we work Roughly 80% of development is containerized. For many companies the complexity is too hard to manage… So they don’t. “Testing in production” is becoming the new normal It’s ironic The person who knows what that the code is supposed to do Is greatly hampered by the process of delivering the code And the business, which needs faster delivery Is taking risks to short circuit its own processes.. 43 A little bit more rain than you expected?

If you’re deploying containers it’s better to develop in them too: • Higher fidelity – OS, runtime, libraries, fixpack levels, all exactly match production • Developers are directly testing the output of the build • Services injected and used as they will be in production • Ability to debug on and exploit containers and Kubernetes So why isn’t development cloud-native today? • History prior to cloud; momentum • Apps deployed to multiple (non-cloud) environments • The ‘container penalty’: • Slow to build initial container • No iterative development • Harder to access logs and other files in the container • Shell access • … • Tools looking to help to remove the container penalty Inner loop becoming more complicated ?

  • The Impact of the Language Server Protocol on Textual Domain-Specific Languages
    Decoupling Language and Editor - The Impact of the Language Server Protocol on Textual Domain-Specific Languages Hendrik Bunder¨ itemis AG, Bonn, Germany Keywords: Textual Domain-Specific Languages, Model-Driven Development, Language Server Protocol, Case Study. Abstract: Model-Driven Software Development using Domain-Specific Languages (DSL) has been widely adopted throughout research and industry. The language workbenches required to efficiently build Domain-Specific Languages and the associated editor support are often deeply integrated into a specific Integrated Development Environment (IDE). Thereby, the chosen Domain-Specific Language workbench predicts the IDE required to use the DSL. Yet, this IDE might not be the best choice for further implementing, testing, and debugging the generated code. A case study was conducted to analyze how the Language Server Protocol could be utilized to decouple the DSL implementation from a specific editor integrated into an IDE. First, the Language Server Protocol capabilities are exemplified by building editor support for an Entity-DSL that is integrated into two different IDEs. Second, a SWOT analysis is carried out to identify strengths and weaknesses as well as oppor- tunities and threats for Domain-Specific Languages utilizing the Language Server Protocol. The case study’s results indicate that the Language Server Protocol enables efficient multi-editor integration. Further, the results of the SWOT analysis imply potential benefits for cross-functional teams specifying a shared domain model. 1 INTRODUCTION liJ (JetBrains, 2018) or Eclipse (Vogel and Beaton, 2013).
