PDF Defining metrics for continuous delivery and deployment pipeline

Kubernetes Monitoring Deploy and manage containers with instant code-level insights. Usability enhancements — Our user experience team is always looking for new ways to make Genesys Cloud more useful and easier to use. An earlier version of this process which you might want to have a look at was introduced by Chris Shayan, when he wrote about the Continuous Delivery maturity matrix below. If you have a long running feature you’re working on, you can continuously integrate but hold back the release with feature flags. It usually helps to raise a couple of simple questions online and with your peers first and answer them before picking any solution.

Another key element in ensuring seamless, continuous deployment iscontinuous integration. In order for automation of deployment processes to work, all the developers working on a project need an efficient way of communicating the changes that take place. In continuous deployment, code changes to an application are automatically tested and released automatically into the production environment.

Continuous Delivery: Reliable Software Releases Through Build, Test, and Deployment Automation

Beyond making sure your application passes automated tests it has to have all the configuration necessary to push it into production. CD encompasses everything from ideation to build to readiness to delivery to production. There is no CI+ CD or CI/CD, continuous delivery includes continuous integration practices. Continuous delivery is popular approach for software delivery, especially for teams that practice DevOps.

While “continuous deployment” and “continuous delivery” may sound like the same thing, they are actually two different approaches to frequent release. To practice continuous delivery effectively, software applications have to meet a set of architecturally significant requirements such as deployability, modifiability, and testability. This experience report describes the journey to continuous delivery with the aim that others can learn from the authors’ mistakes and get their teams deploying more frequently.

Our colleague Zhamak Dehghani covers this in more detail on her Data Mesh article. Therefore, having integration and data Contract Tests as part of our Deployment Pipelines to catch those mistakes is something we strive for. To implement the “model as service” pattern, many of the cloud providers have tools and SDKs to wrap your model for deployment into their MLaaS platforms, such as Azure Machine Learning, AWS Sagemaker, or Google AI Platform. Another option is to use a tool like Kubeflow, which is a project designed to deploy ML workflows on Kubernetes, although it tries to solve more than just the model serving part of the problem.

This means constantly updating and shipping new versions of production code. We take them to a repeatable and defined operation level in each of the practices that make up the model. Validating on staging – Features that are ready for feedback get pulled into the validating on staging step to be integrated with the rest of the system in a staging environment, and then tested and validated. Decoupling the web farm functionality from the physical launch eliminates the need for a monolithic release. It also increases Business Agility by allowing components of the solution to be delivered in response to frequent changes in market need.

Indicators such as deployment frequency, change lead time, and incident meantime to recovery are often improved by implementing CI/CD with continuous testing. However, CI/CD is just one process that can drive these improvements, and there are other prerequisites to improving deployment frequencies. Devops teams also automate performance, API, browser, and device testing. Today, teams can also embed static code analysis and security testing in the CI/CD pipeline forshift-left testing. Agile teams can also test interactions with third-party APIs, SaaS, and other systems outside of their control using service virtualization.

The value of continuous delivery

SaaS solutions generally let you focus more on your core product as you don’t have to spend time on maintaining your infrastructure and keeping all dependencies updated at the cost of some flexibility. Additionally, SAFe’s DevOps Health Radar allows ARTs to quickly assess the performance of their delivery pipelines and identify specific DevOps practices that can be applied to optimize them. Percent Complete and Accurate (%C&A) represents the percentage of work that the next step can process without needing rework. The percent complete and accurate metric helps identify the steps where poor quality might be occurring and causing longer lead times, resulting in delays of value delivery. Figure 4 indicates that 20% of the time the work moving from the ‘Design’ step to the ‘Code’ step, needs to be reworked. Improving the %C&A metric is also essential to improving the flow of value.

We sometimes call the approval stages the software must pass through to go live quality gates. There are also practical steps that allow validation of software, like deploying the correct software version to a test environment. In this category we want to show the importance of handling this information correctly when adopting Continuous Delivery. Information must e.g. be concise, relevant and accessible at the right time to the right persons in order to obtain the full speed and flexibility possible with Continuous Delivery. Apart from information directly used to fulfill business requirements by developing and releasing features, it is also important to have access to information needed to measure the process itself and continuously improve it.

Evolving Intelligent Systems without Bias

Agile Manifesto, released in 2001, revolutionized the software development industry by introducing agile methodologies breaking down the development process into small chunks with faster feedback loops. Is a development method that takes code changes, tests them in a realistic environment, and automatically releases them to production. It’s built on Argo for declarative continuous delivery, making modern software delivery possible at enterprise scale. IaC automation tools can support best practices and may be necessary to keep the infrastructure building process competitive. They enable effective infrastructure configuration and reduce the cost and effort of provisioning infrastructure.

  • Collecting monitoring and observability data becomes even more important when you have multiple models deployed in production.
  • With DevOps, developers, usually coding in a standard development environment, work closely with testers and IT operations teams to speed software builds, code commits, unit tests, and releases—without sacrificing reliability.
  • However, from our experience you will have a better chance of a successful implementation if you jump start the journey with a dedicated project with a clear mandate and aggressive goals on e.g. reducing cycle time.
  • Because of its modular design, Kubernetes allows alteration of individual pods inside a service, as well as seamless transitions between pods.

The levels are not strict and mandatory stages that needs to be passed in sequence, but rather should serve as a base for evaluation and planning. Stefania Chaplin is looking at OWASP recommendations and Kubernetes best practices to find out more about how to secure microservices and reduce vulnerability traversal. Engineers use CI/CD in other areas, including network configuration, embedded systems, database changes, IoT, and AR/VR.

Decrease deployment errors that require rollback action to the pre-existing versions. Tags are required in this mode to communicate when the release is done as it’s an external manual process. Before submitting changes, check to see if a build is currently in the “Successful” status.

If you have open source projects, you can test them with either solution. As mentioned, a hosted solution doesn’t require maintenance of the servers on your side, which leaves more time for you to work / code on your product. If you prefer a self-hosted solution you need to administer your own server. The SaaS solution doesn’t require this, but it might be more limiting in case you require some edge case features.

Integrations

Continuous deployment is the next evolution of the CI/CD pipeline once an organization has mastered continuous delivery. The primary goal of DevOps automation is to remove as many manual processes as possible, so continuous deployment enables seamless and rapid deployments to meet the changing needs of customers. In this example, the goal is to achieve a smooth rollout of the finished product.

Business stakeholders and VPs are lamenting the fact that with continuous delivery comes continuous responsibility. This website is using a security service to protect itself from online attacks. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL continuous delivery maturity model command or malformed data. Many organizations struggle to manage their vast collection of AWS accounts, but Control Tower can help. Synopsys is a leading provider of electronic design automation solutions and services. Now that you understand the benefits of a CD pipeline, let’s review how to build one.

Unified cloud-native platform vs Splunk

Simpler releases—development teams spend less time preparing codebases for release and don’t combine multiple changes into a large, complex release. Instead, developers update and release code in small increments—ideally, every time they make a change. Evolving an intelligent system to choose and improve ML models over time can also be seen as a meta-learning problem.

By doing so, you avoid integration challenges that can happen when waiting for release day to merge changes into the release branch. Continuous delivery is the layer that sits on top of continuous integration. Continuous delivery, which only works if continuous integration is in place, involves running extensive regression, UI, and performance tests to ensure that the code is production-ready. For continuous delivery to work effectively, fundamental principles should be in place.

Continuous Delivery: Basic Concepts and the GitOps Revolution

Pairing continuous integration with continuous delivery ensures code worked on by multiple developers from multiple locations is integrated into a single repository. It is tested at the subsystem level, including functional, performance and security tests. These ensure that the developed code meets the quality standards of an end user and the specifications of the project. Integrated subsystems require UI and networks tests, and may still need other functional, performance and security reviews.Automate these tests wherever possible. At this phase in the pipeline, the application components can be kept separate to form microservices or integrated together as one complete system. It’s no secret that people prefer higher-order work to manual, repetitive tasks.

It’s important that stakeholders can visualize and track the ongoing work, even though a significant portion of it is automated. They need the ability to establish Work in Process limits to improve throughput and identify and address bottlenecks. Successful enterprises already have a delivery pipeline—otherwise, they wouldn’t be able to release any value at all. But too often they are not automated, contain significant delays, and require tedious and error-prone human intervention. This, in turn, causes organizations to delay releases, increasing their size and scope (“We’ll release when it is big enough”). This is opposite of the SAFe Principle #6, which promotes limiting Work in Process and reducing batch size.

Continuous delivery is an approach for software delivery in which development teams produce and test code in short but continuous cycles, usually with high degrees of automation, to improve software quality. This process enables development teams to build, test and deploy software quickly by encouraging more incremental updates, rather than spending a large portion of time on a complete overhaul of a given product. Advanced practices include fully automatic acceptance tests and maybe also generating structured acceptance criteria directly from requirements with e.g. specification by example and domains specific languages.

Build & Deploy

Because the model is evolving, we must ensure that it won’t break any contract with its consumers, therefore we need to test it before deploying to production. Once in production, we can use the monitoring and observability infrastructure to gather new data that can be analysed and used to create new training data sets, closing the feedback loop of continuous improvement. Because continuous deployment does away with human safeguards against defective code, teams should use it for frequent, small, incremental updates, as opposed to wholesale changes to large systems. Finally, you need to be able to back out from updates that cause users to experience errors or crashes not caught by the automated tests. Going from continuous integration and continuous delivery to continuous deployment takes yet another step toward automating the software development lifecycle. By practicing continuous deployment, you ensure that every change is robust and clean enough that it can be immediately released to users—or customers—without any manual intervention.

Many teams operating CI/CD pipelines in cloud environments also use containers such as Docker and orchestration systems such asKubernetes. Containers allow for packaging and shipping applications in a standard, portable way. Containers make it easy to scale up or tear down environments with variable workloads. Continuous integration not only packages all the software and database components, but the automation will also execute unit tests and other types of tests. Testing provides vital feedback to developers that their code changes didn’t break anything.
