The Defence DevSecOps Service

Use the Defence DevSecOps Service (D2S) to build, test and deploy secure software as highly available cloud-native services.

The D2S platform is based on Red Hat’s OpenShift Container Platform(opens in new tab) (OCP) and hosted on MODCloud’s iACE infrastructure(opens in new tab).

The D2S service offers:

  • an integrated DevSecOps toolchain
  • support for incident management
  • learning and guidance
  • a Community of Practice

You can use D2S to develop high code applications using a DevSecOps approach which cannot use low code or commercial off-the-shelf (COTS) solutions. You can also migrate existing containerised cloud-native applications for deployment on D2S. Your team must maintain the application throughout its life cycle.

Find out more about the platform


With D2S, you can:

  1. Securely deploy applications on highly resilient and scalable infrastructure
    D2S is hosted on MODCloud’s hybrid (private and public) infrastructure. D2S applications can be deployed to virtual and physical locations so that services can be delivered from anywhere.

  2. Automate the build and deployment of applications for speed and agility
    D2S offers a DevSecOps pipeline with built-in automation, security and continuous integration/continuous delivery (CI/CD) capabilities to quickly deploy applications.

  3. Accelerate software development through the reuse of code and common components
    Having most Defence application teams on one central platform lets you share code, software and data.

  4. Start building your application straight away
    D2S is an assured platform and toolkit so you can quickly access our development and test environments.

As a developer you can:

  1. continuously deliver code into production with shorter development cycles
  2. develop features quickly
  3. build, run, inspect and manage your applications in real-time
  4. use OCP tooling to quickly build CI/CD pipelines

As a team lead you can:

  1. minimise delivery time between development, test and production environments
  2. reduce application development costs through reusable technologies
  3. test and check the security of your application during development with built-in automated tools

Deliver applications quickly

D2S saves time and money for teams who deliver software applications and digital services to Front Line Commands.

We offer a common DevSecOps approach, so teams do not have to build new platforms and pipelines.


  • avoids duplication through the reuse of code, technologies and data
  • reduces running costs
  • minimises up-front assurance processes
  • lets you focus on higher priorities in Defence
  • makes software more portable and resilient
  • increases knowledge sharing across Defence


The D2S cost model shows how we calculate prices such as memory and storage, using application sizes of small, medium or large. You can contact the D2S team to discuss what you may need.
