In today’s tech-driven world, Software as a Service (SaaS) has emerged as a game-changer. The SaaS Development Lifecycle (SaaSDLC) is the roadmap for creating cloud-hosted services that adhere to the core principles of SaaS. This article explores the various phases of SaaSDLC, shedding light on the crucial steps involved.
The SaaS Development Lifecycle is an adaptation of the traditional iterative software development process, with additional essential phases specific to cloud-based services. These phases include Evaluation, Subscribing, and Operations, which are critical for the success of SaaS development.
The first phase, Envisioning, involves identifying new business opportunities, expanding customer bases, and extracting more value from intellectual property. This phase is similar to traditional software envisioning, but SaaS offers greater opportunities for innovation and scalability.
Key participants in this phase include business leaders, technology roles like CTOs and architects, and cloud experts. Their combined expertise ensures a well-rounded vision for the SaaS service.
Platform Evaluation is a dedicated phase for assessing cloud providers. The choice of a cloud provider is crucial, especially for mission-critical systems. This phase aligns architecture proof points with a cloud provider’s capabilities.
A task force of business and technology experts works together to evaluate cloud platforms. They refine functional and architectural proof points to make an informed choice.
The Planning phase sets the course for delivering the SaaS service predictably. The complexity and size of the service determine the rigor of activities and deliverables. Planning includes feature requirements, solution architecture, project schedules, and risk mitigation.
Project and product managers, architects, and IT professionals play a crucial role in shaping the plan.
The Subscribing phase involves acquiring a production-quality subscription. This phase drives upgrades, support processes, and business continuity based on the trial experience. It also includes negotiating service level agreements and pricing contracts.
Key participants include the Chief Security Officer, architects, procurement managers, IT professionals, and cloud experts.
The Developing phase is where design specifications are translated into code and documentation. It involves iterative development, continuous testing, integration with cloud and on-premise systems, and end-user involvement for quality service delivery.
Product managers, solution architects, developers, testers, and end-users work collaboratively to bring the service to life.
The decision-making in this stage is primarily implementation-oriented:
The Operations phase is critical for SaaS success, as it involves deployment, support contracts, compliance, security, and shared infrastructure. Activities in this phase ensure the service’s systemic qualities align with the cloud platform’s operational aspects.
IT professionals, solution architects, support engineers, and escalation leads play key roles in this phase.
The SaaS Development Lifecycle offers a structured approach to creating cloud-hosted services, ensuring that they align with the principles of SaaS. While the initial phases require meticulous evaluation and planning, subsequent SaaS efforts can leverage previous knowledge. The SaaSDLC is a valuable guide, not only for ISVs but also for enterprise IT departments.
