Connection to the RDE

How files are synchronised between your local machine and a Remote Development Environment (RDE) and how you interact with an RDE is a central question of using DevStack.

Methods of Source Code Synchronisation​

There are 3 ways how DevStack can synchronise your local machine with an RDE. They balance different aspects of developing like ease of use, source code security and needed internet connectivity.

note

A distinctive feature of DevStack is the possibility to use it with an unstable internet connection. Read on to see the connection requirements of the various synchronisation methods.

File and Folder Synchronisation​

This is the default way, it focuses on ease of use. DevStack uses an intelligent delta synch to synchronise content from a local folder to an RDE. This requires the initial setup of the RDE content locally. The source code is saved locally and can be worked on even with an unstable internet connection. Moreover, you are not restricted in the tooling that you use (e.g. your choice of IDE).

Pros

  • Allows the use of whatever tooling you're used to.
  • Can work with unstable internet connection.
  • File access is as fast as locally.

Cons

  • Source code is saved locally, hence less secure than mounting or pure SSH synchronisation.
  • Initial (minor) setup of RDE content locally.

File and Folder Mounting​

A second option that provides a middle ground between security and easy of use. DevStack mounts RDE content locally. Changes made locally are synchronised to the RDE. The source code is available locally, although only through the mount. This means that you need a stable internet connection. Again, you are not restricted in the tooling that you use (e.g. your choice of IDE).

Pros

  • Allows the use of whatever tooling you're used to.
  • No initial local setup of RDE content needed.

Cons

  • Source code is cached locally while workstation is powered on, hence less secure than pure SSH synchronisation.
  • Needs stable internet connection.
  • File access is slower than locally -> Searching is slower than locally. Reads and writes are slower than locally.

Pure SSH​

The ultimate solution for source code security. There is no local mount or folder. DevStack lets you access source code on an RDE only through an SSH capable IDE. A stable internet connection is required. If your current tooling is not SSH capable, you need to change the tooling you use.

Pros

  • Source code stays remote for maximum security.
  • No initial local setup of RDE content needed.

Cons

  • Supports only SSH capable tooling.
  • Needs stable internet connection.
  • File access is somewhat slower than locally -> Reads and writes are slower than locally.

Interacting with RDEs​

DevStack lets you interact with RDEs in several ways.

Via the Self Service Portal​

The self service portal should cover most needs of a development workflow. You can configure, deploy, start and stop RDEs. The self service portal has a dedicated view for working with logs.

Directly via SSH​

If there is something that you cannot do with the self service portal, DevStack lets you connect to an RDE directly through SSH and have the full power of using a terminal.

Synchronisation of Dedicated Folders​

Besides source code synchronisation, you can set up a separate synchronisation for other dedicated folders. The synchronisation in DevStack is one way, with a definable direction (RDE -> local or local -> RDE).

If there is information on the RDE that you would like easy and direct access to, you can set up a synchronised folder RDE -> local.

note

Setting up a synchronised folder for logs is a great example of how you can make use of this DevStack feature.

Switching between multiple RDEs​

A benefit of RDEs is that you can have parallel multiple instances ready to go. This is great if you're used to working with multiple branches and builds. Switching to an RDE takes considerably less time then branch switching.

Each RDE can represent a different branch, built and ready to be used. Switching between RDEs is as simple as connecting to another RDE using the self service portal. DevStack takes care of the required steps e.g. mapping corresponding local folders, establishing the SSH connection, etc.
