What Is a Deployment Strategy?
A deployment strategy is more than just a mere step-by-step plan, it is an all-encompassing and extensive approach that extends to cross-functional team collaborations and planning to the implementation, testing and analysis of a software deployment.
The purpose of an effective software deployment strategy is to ensure a successful software application launch and experience for the users – faster release and change roll-outs, minimized downtime for issue resolution, streamlining operations, risk mitigation, and evaluation and analysis.
Types of Deployment Strategies
It is crucial to choose a deployment strategy that suits the specific needs of the software. While there are many strategies to choose from, let’s have a look at the most widely practised strategies.
1. Canary Deployment
Canary deployment is a popular strategy in DevOps. Taking its inspiration from miners’ use of canary birds to detect toxic gases in the mines, this approach involves deploying a new version of software to a small group of users, the ‘canaries’. The DevOps team closely monitors the performance, stability and user experience to identify and resolve any potential bugs and issues before gradually deploying the software to a larger user base.
This deployment strategy offers a controlled approach and allows for instant rollbacks in case of user dissatisfaction or potential technical issues.
2. Blue-Green Deployment
Also known as red-black deployment, this strategy in DevOps includes using two identical environments – ‘Blue’, the environment currently in production and ‘Green’, the environment used for the launch of a new version.
This strategy is ideal for a time-sensitive seamless shift that allows redirecting traffic from the blue environment to the green environment while keeping the blue environment at stand-by in case of rollbacks.
3. Rolling Deployment
This Software deployment approach, also known as ‘phased rollout’ involves gradually deploying new software versions across the system. This allows slow replacement of the previous versions of an application with the latest version by replacing the infrastructure.
While this deployment strategy is quicker than the blue-green deployment strategy, it complicates the rollback process.
4. Shadow Deployment
Shadow deployment is yet another widely used deployment strategy that involves running the old and new versions of an application simultaneously. In short, a replica of the live environment is created to allow the DevOps team to analyse the performance of the latest application in a production-like environment without affecting the users.
How DevOps Changed the Software Deployment Landscape
Gaining momentum in 2007 and 2008, the DevOps movement emerged directly in response to the dissatisfaction expressed by IT professionals regarding the dysfunction between IT and software development teams. DevOps was created to improve the collaboration between developers and operations teams and change traditional software development encompassing manual handoffs and extensive development cycles. DevOps has since come a long way, keeping up with the demands of digitalization and digital transformation.
1. Code Integration
Integration of DevOps practices such as CD/CI has automated the process of code integration in the source code repository. The goal is to accelerate the software deployment by conducting tests to ensure the functionality of the code and resolve any issues or bugs in the later stages to ensure that the software is deployable.
2. User Experience
Using DevOps in the deployment strategies also ensures a positive user experience. The users receive software applications that undergo rigorous automated testing, monitoring, early detection of potential bugs and issues and repeated feedback loops.
3. Security
At the same time as improving the workflow, and optimising the resources, agility and user experience, DevOps is also crucial for maintaining security at every step of software deployment – a concept called DevSecOps.
4. Resource Management
DevOps processes like Infrastructure as Code (IaC) have replaced the manual infrastructure processes – setting up, maintaining and updating operating systems, database connections, and storage, with a code-integrated automated process. This allows for a time-efficient and reliable development, testing and deployment of software.
With the growth of DevOps in the digital industry, the software deployment and development have improved significantly. By using key concepts such as CD/CI (Continuous Delivery/Continuous Integration), IaC (Infrastructure as Code), Version Control System (VCS) and automation, software deployment processes have and will continue to evolve for better, secure and faster delivery.
AI in DevOps & Software Deployment
Because both DevOps and AI put automation at the forefront, the synergy of the two is powerful and transformative. Owing to the advancement in AI and machine learning, DevOps practices have significantly evolved. The integration of AI in the software development lifecycle revolutionized the methods used by the teams to build, test, deploy and monitor software applications.
Let’s take a look at some of the most significant impacts of AI on DevOps and subsequently in software development and software deployment.
1. Data-Driven Decisions
AI-driven analytics across vast datasets provides the DevOps teams with actionable insights on user feedback, business KPIs, and performance metrics. These comprehensive data-driven insights by the AI algorithm allow the DevOps teams to build collaborative and strategic plans for continuous improvement and innovation in the software development and software deployment process.
2. Problem Resolution
AI-driven Incident management systems aid in building resilient IT environments. AI systems can accelerate issue resolution by detecting an issue, responding to the issue and identifying the root cause for the issue in an automated manner. AI systems can also forecast possible issues by learning the pattern from old data and detecting live anomalies. This ensures a reliable and secure system and improves the overall system service.
3. DevSecOps
AI enhances security by automating threat detection, identifying anomalies and mitigating cyber threats. Machine learning algorithms continuously monitor and analyze network traffic to detect malicious activities and mitigate the risks of breaches. By providing real-time alerts, AI can improve threat detection and safeguard sensitive data by fortifying cyber defence
4. Resource and Infrastructure Management
AI facilitates the DevOps teams with efficient resource utilization. By optimizing the use of cloud infrastructure and automating resource allocation based on demands, AI improves the software development and software deployment processes. AI and machine learning algorithms also improve the management and scalability of complex infrastructures by analysing workload patterns and minimizing downtime. By optimising resource and infrastructure management, AI enables an organization to improve its scalability, resilience, workloads and performance.
Conclusion
In conclusion, while the integration of DevOps has significantly improved and revolutionized the software development lifecycle, its role and contribution to emerging technologies are also noteworthy.
In an era of continuous digital transformation, DevOps is at the forefront of the seamless integration of technology like AR, Blockchain (DApps), IoT devices, edge computing and cloud computing.
