Eclipse Che introduces a new kind of developer tool that runs directly on Kubernetes and is accessible through a web-based IDE. The container architecture enables easy and rapid onboarding of new team members while eliminating workstation maintenance costs and limitations, all while leveraging a VS Code-like experience. The release of Che 7.0 by the open source community goes further by making the developer environment consistent, repeatable and reproducible. Now available for mainframe-based code with the Che4z subproject, teams can collaborate on cross-platform applications and bridge the distributed/mainframe divide. The panel with discuss how the Eclipse Che IDE and workspace server drive developer productivity and improve overall software delivery.

3. What are IDEs?
Integrated Development Environment (IDE)
Source code editor
● Syntax highlighting
● Code Navigation
● Auto-completion
● Check bugs while typing
Developer tasks automation
● Compile/Build
● Package
● Run Application
● Run Tests
Debugger
● Testing program/application
● Show application state
● Halt at particular point of code
● Stepped execution

9. Why Eclipse Che?

10. Development time spent on configuration and setup
Activities that require configuration and
setup:
- Onboarding on a new project
- Switching between different projects,
technologies
- Fixing a maintenance branch
- Reviewing a pull request
- Upgrading tools, plugins, dependencies
- Trying out a new technology
24%
of a dev team’s week is spent on
building and maintaining
developer environments
Config and Setup

11. Modern application architectures increase complexity
Monolithic applications:
- Source code has all the
dependency graph
- Connections between services
are obvious
- IDEs understand the app and
allow developers to jump to
definition
Services based applications:
- Everything is broken up
- Connections are unclear
between the services
- IDEs understand each service,
but not the interconnection

12. Anyone, anytime can contribute to a project
without installing software.

17. The Eclipse Che Solution

18. Eclipse Che Workspace
Defining a new kind of workspace
Containerize everything you need to develop, build, run, test and debug your application.

19. Defining a new kind of workspace
Containerizing the IDE: zero install and automate configuration
Extended Eclipse Theia, to
provide a VSCode-like

The devfile provides easy to configure, highly
reproducible definitions of portable developer
environments.
It is a declarative abstraction of a replicable
developer workspaces, which includes the runtime
environments, the source code of the projects
mapped to repositories and the tools, plugins and
commands needed to code, build, test, run and debug
a project.
