Streamlining Application Deployment: A Monorepo Approach

Streamlining Application Deployment A Monorepo Approach Informed

This blog describes the challenges of deploying monorepo applications tightly coupled with infrastructure. They include versioning and dependency issues, which cause unpredictable application stability and consistency issues. We’ll also look at how SemVer versioning standard and tagging streamline the software release process.

Challenges of Deploying Monorepo Applications with Tightly Coupled Infrastructure

Deploying monorepo applications with tightly coupled infrastructure presents has challenges to carefully considere.

At Informed, we have a diverse range of applications, including Python container-based, Python image-based, Ruby container-based and Ruby image-based applications. Each of these applications has its own unique build system that is closely tied to specific infrastructure components. For example, Python image-based applications require different infrastructure components than Python container-based applications.

Creating versioned artifacts for each application is critical, ensuring we can deploy controlled and predictable updates. However, this becomes increasingly complex when dealing with a mixed bag of resources and modules. It is challenging to create versioned artifacts that are tightly coupled with specific versions of infrastructure components.

In addition to versioning challenges, there are potential conflicts between applications due to dependencies on shared infrastructure components. This can lead to unforeseen issues that are difficult to diagnose and resolve. And it can significantly impact our ability to deploy updates and maintain application stability.

Streamlining Software Releases with SemVer and Tagging

As mentioned earlier, managing software releases is a complex process, particularly when dealing with multiple teams and systems.

To simplify and streamline our release process, we utilize the SemVer versioning standard and tagging. So, we are able to effectively coordinate releases across different environments and teams, ensuring consistency throughout the process. 

Let’s look at how we use SemVer and tagging to streamline our software release process, exploring the benefits and challenges of this approach.

SemVer is a standardized approach to versioning software releases. It involves a three-part version number: MAJOR.MINOR.PATCH with release candidate. This numbering scheme provides a clear and consistent way to identify the specific application version being deployed. When a team is ready to release a new version of the software, they commit a change specifying the type of change: MAJOR, MINOR, PATCH, or FIX in the commit message. 

For example, a commit message may be “MAJOR: Add functionality to service X”. After merging the commit to the main branch, the CI/CD workflow will create a tag based on the commit message, such as “serviceX-1.0.0-rc1”, indicating this is a major release candidate for Service X. 

Using SemVer and tagging helps streamline the software release process by providing a clear and consistent way to communicate changes and updates to stakeholders. Additionally, it helps ensure consistency across different environments by promoting versioned artifacts referencing specific tags. 

For example, we can easily promote the artifact to different environments by referencing the specific tag marking the release. This ensures that the same artifact is deployed across all environments, reducing the risk of inconsistencies and errors.

Using Invoke for triggering deployment

Let’s take a closer look at the tools driving these processes.

We have implemented an automated deployment tool using the Invoke library. The tool plays a critical role in ensuring that releases are streamlined and error-free.

The deployment process is complex, especially when deploying to multiple environments, such as development, staging, qa, and production. There are many manual steps involved, which can lead to errors, delays, and inconsistencies.

With Invoke, teams can deploy their applications to sandbox and development environments, as well as promote environments. This means that if a team wants to replicate an entire environment in another location, they use Invoke to deploy all selected services to that environment. It helps with local and cloud deployment, as well as promote environments and kick off regression tests.

This means that teams can use a single tool to manage the entire deployment process, rather than relying on multiple tools.

Conclusion

Managing software releases and deployments is a complex process, especially when dealing with multiple services and teams. By following industry best practices such as SemVer versioning and using tools like Invoke, you streamline the process and ensure consistency across different environments.
