Business is accelerating, and experience – for customers, partners and employees–is everything. This means nearly all applications need to be enhanced with new features, security updates and bug fixes on ever-shorter cycles. But isn’t rushing new code into production, especially in cloud environments, a recipe for mistakes, security vulnerabilities and user frustration? Not if the right approach is taken.
Continuous delivery (CD) enables development teams to rapidly and regularly deploy software updates into production systems without jeopardizing user experience or creating security risks. Battle-tested open source CD orchestration solutions, including Spinnaker and Argo, provide a cost-effective way to deliver secure, high-quality software at massive scale to multi-cloud and Kubernetes environments.
What is Continuous Delivery (CD)?
Most software development teams suffer from quality issues related to outages, tracking down bugs and security vulnerabilities, complex upgrades, release rollbacks and more. According to a 2020 report by the Consortium for Information & Software Quality™ (CISQ™), software quality suffers as companies rush to add more value at greater speeds. In 2020, the cost to companies was $2.08 trillion in the U.S. alone.
CD relies on a framework of stakeholder collaboration, process automation and continual and rigorous risk assessment and feedback to ensure a smooth, high-volume flow of high-quality code is deployed to production systems. When done right, CD reduces software development risks by enabling development teams to deploy changes such as new features, configurations, bug fixes and even experiments into production safely, quickly and sustainably. It also reduces costs associated with software deployments, failed releases and customer frustration and attrition.
With effective CD workflows in place, development teams gain confidence and are more productive, delivering better products faster while eliminating the frustration of missed release dates, management wrath and the blame game associated with software bugs and vulnerabilities making it into production.
Open Source CD Solutions
Prior to the rise of open source CD solutions, companies often relied on point automation using scripts. These could improve efficiency a bit, but when companies moved from the monolithic architecture of a mainframe or on-premises servers to a microservices-based production environment, the scripts could not be easily adapted or scaled to cope with the more complex environment. This led to the formulation of continuous delivery orchestration solutions that could ensure code updates would flow to their destination in a repeatable, orderly manner.
Two highly popular open source CD solutions have emerged, Spinnaker and Argo. Spinnaker was developed by Netflix and extended by Google, Microsoft and Pivotal. It was made available on GitHub in 2015. Spinnaker creates a “paved road” for application delivery, with guardrails to ensure only valid infrastructure and configurations reach production. It facilitates the creation of pipelines that represent a software delivery process. These pipelines can be triggered in a variety of ways, including manually, via a cron expression, at the completion of a Jenkins Job or other pipeline and other methods. Spinnaker also provides cluster management, as well as visibility into an application’s cloud footprint, letting users resize, delete, disable and even manually deploy new server groups using strategies like blue-green deployments.
Argo CD, a container-native deployment engine for Kubernetes, supports CD pipelines, enabling the automated deployment of applications within Kubernetes. Introduced in 2018, Argo CD utilizes the Argo GitOps Engine, an open source library that implements core GitOps features. It allows users to manage, automate and audit the software deployment with Git as the source of truth. Features of Argo CD include drift detection, the analysis of the health of application resources and a real-time view of application activity.
As open source software, both solutions offer all the benefits that the open source model offers, including low start-up costs, rapid and continual innovation and paid support when it becomes necessary.
A CD Automation Success Story
Symphony provides a cloud-based collaboration platform for financial institutions that are highly regulated and render services to millions of customers, so the solution must meet rigorous standards for security and regulatory compliance. The company wanted to enable a multi-tenant system to improve performance and reduce the cost of operations for each client. However, the existing software delivery system created bottlenecks in integration testing, long triage times and manual handovers of releases to site reliability engineering (SRE). The ever-growing number of delivery pipelines and software delivery environments also increased infrastructure costs and the burden on human resources, making it difficult to deliver features faster and ensure compliance at scale.
Symphony determined it needed a completely new CD solution supporting infrastructure and software delivery workflows that they could retrofit into their existing platform. The solution needed to support infrastructure-as-code, pipeline-as-code and configuration-as-code, while providing visibility, auditability and faster approval processes. Symphony opted for a CD solution that harnessed the power of both Spinnaker and Argo to automate the entire end-to-end CD process, including pipelines for infrastructure, deployment, testing and promotion to production deployments. With the solution, Symphony was able to slash the time required to onboard new environments by 98%–just 10 minutes to get the infrastructure and platform ready for the client. This also allowed for fast and frequent changes.
With automated CD in place, the company enjoyed significant cost optimization through automation. It was also able to increase security and compliance through automatic policy checks that continually enforced compliance across the stages of each pipeline–without compromising delivery speed.
Getting Started
As you review potential CD solutions, ensure they can deliver the required level of:
- Ease of setup and configuration
- Visibility and collaboration
- DevOps tools integration and extensibility
- Built-in deployment environment support
- Security and governance
- Workflow flexibility
- Performance, uptime and scalability
Get an Expert Assessment
While the benefits of a CD solution are enormous, deploying one is not trivial. It pays to make good choices to get it right the first time. A professional assessment of your existing environment and processes can help you in several ways, including:
- Exposing your current silos
- Identifying the bottlenecks in your software delivery process that can be automated
- Identifying productivity improvement opportunities for everyone involved in the delivery journey
- Giving you the insights you need to make an informed decision about your CD solution.
- Providing advice on best practices that can transcend the deployment process to the next level of efficiency and quality
If your company requires the rapid delivery of secure, high-quality software releases, the time to deploy a continuous delivery solution is now.
