Cloud technology has changed the traditional approach to the conception, development, and deployment of applications. As businesses increasingly migrate towards cloud-based solutions, a crucial challenge emerges: how can we helm the intricacies of cloud software development while maintaining flexibility and efficiency? This article clears the concept of the Cloud Software Development Life Cycle (CSDLC), shedding light on how an agile, iterative approach ensures success in business cloud migration.

Components of Cloud Software Development Life Cycle

The ascent of cloud technologies provides developers with unprecedented scalability and distributed systems’ sustainability. The potential for flexible computing power offers a paradigm shift in application development, presenting developers with novel opportunities and new specific challenges. Multi-layered IT infrastructures, the complexity of microservices architecture, vendor lock-in and imperative security considerations are the most noticeable among them.

Our earlier post explored the agile principles of the Software Development Life Cycle (SDLC), a reliable guide to creating traditional online applications. However, the transition to developing cloud apps demonstrates the restriction of standard SDLC practices, particularly those oriented in the conventional crafting monolithic desktop and web applications.

Obviously, the usual sequence of stages: Planning – Design – Implementation – Testing – Deployment – Support is not enough to describe the entire scope of operations for building a cloud application. Moreover, the standard SDLC is only one of many similar cycles of the broader Cloud Software Development Life Cycle (CSDLC), carried out at various levels of the cloud IT system being created. Let’s clarify what other elements make up the CSDLC and determine the essence of its specificity.


The planning is the foundational phase in the Cloud Software Development Life Cycle, focusing on establishing a strategic roadmap and aligning development efforts with overarching business goals. It contains several key activities to ensure a well-defined and efficient development process in future:

  • to clarify the primary objectives and goals of the cloud application;
  • to establish a comprehensive understanding of how the app aligns with broader business strategies;
  • to identify the anticipated benefits and outcomes for the company;
  • to evaluate potential risks associated with the development and deployment of the cloud product;
  • to assess factors impacting the project timeline, budget, and overall success;
  • to develop strategies to mitigate identified risks and enhance project resilience;
  • to define a financial framework that aligns with the scope and objectives of the cloud application;
  • to allocate resources effectively, considering development costs, infrastructure requirements, and potential contingencies;
  • to ensure transparency and accountability in budget management.

System design

This CSDLC phase serves as the architectural cornerstone, where the vision of the cloud software transforms into a concrete technical plan. It is guided by a multifaceted purpose, woven to align technical decisions with common business objectives.

The foremost target is to meticulously evaluate and select the most fitting cloud service provider, considering scalability, reliability, performance, and cost-effectiveness factors. This decision lays the groundwork for the subsequent design activities.

In the pursuit of specificity, the phase delves into defining the intricate details of needed cloud services like SaaS, PaaS, or IaaS and related infrastructure like computing resources, storage solutions, and network configurations. The goal is to tailor these choices to the product’s unique requirements, ensuring a customized and optimized IT system.

Concurrently, the phase addresses the key decision of selecting a technology stack. It involves reasonably evaluating languages, frameworks, and other tools to underpin the development process. The emphasis is on compatibility with the chosen cloud services and infrastructure, striving for a tech stack that harmonizes performance, security, and scalability.

Security, compliance, and management tools constitute another critical facet of this stage. The aim is to fortify the cloud application against threats by implementing robust security measures. Simultaneously, adherence to industry standards and regulations is ensured for compliance. Integrating management tools empowers the continuous monitoring, analysis, and optimization of the cloud environment, fostering an environment of efficiency and reliability.

Negotiation and agreements

This phase is characterized by structured negotiations, contractual agreements, and establishing crucial partnerships, marking a critical transition from planning to the practical implementation of the cloud application.

The primary purpose of this component is to formalize the collaboration between the involved parties — be it the development team, cloud service provider, or any other stakeholders. At the forefront is the negotiation of subscriptions and Service Level Agreements (SLAs) with the chosen cloud vendor. That involves a detailed discussion and alignment of expectations, defining the terms of service, performance metrics, and delineating responsibilities on both sides. The goal is to create a robust framework – Quality of Service (QoS) Agreements – that ensures the decent delivery of cloud services and establishes clear guidelines for issue resolution and support.

Simultaneously, this phase extends to negotiating Statements of Work (SoW) with the development team. These agreements outline the specific deliverables, milestones, and timelines expected from the developers. Clarity on project scope, development methodologies, and communication protocols is established, fostering a shared understanding between the client and the development service provider.

Development and testing

The actual coding and construction of the cloud application characterize this critical stage. It is followed by a comprehensive testing regimen to ensure its robustness, functionality, and adherence to quality standards.

The cloud-native application is usually broken down into small, independently deployable services. Each microservice undergoes its development cycle, including planning, coding, testing, and deployment. This approach allows for a more granular and focused software creation process, enabling teams to independently work on specific features or functionalities.

Repeating the standard SDLCs for each microservice promotes flexibility, scalability, and agility in the development process. It facilitates continuous integration, allowing developers to integrate changes frequently, and automated testing ensures that each microservice operates as intended. This iterative approach is well-suited for cloud environments’ dynamic and distributed nature.

The development phase consists of several key tasks to be accomplished by devs:

  • Code engineering
    Programmers execute the coding and development activities based on the agreed-upon app specifications, creating individual components, modules, and the overall system architecture.
  • Microservices and orchestration
    Cloud engineers adopt microservices architecture and orchestration techniques to enhance scalability, maintainability, and flexibility in deploying cloud applications.
  • Continuous integration
    DevOps implements Continuous Integration (CI) practices, facilitating the seamless integration of code changes into a shared repository and ensuring early detection of potential issues.
  • Automated testing
    QA testers employ automated testing methodologies to validate the developed code rigorously. That includes unit, integration, and system testing to ensure each component functions as intended.
  • Scalable testing
    Developers address the complexities of cloud computing by employing scalable testing methods that account for the distributed nature of cloud systems.
  • Deployment preparation
    The team prepares the application for deployment by finalizing configurations, managing dependencies, and ensuring the developed software aligns with the negotiated Service Level Agreements (SLAs).
  • Security integration
    Cloud security specialists integrate and validate security measures within the codebase to safeguard against potential vulnerabilities and ensure compliance with industry and regulatory standards.
  • Quality assurance
    The QA team conducts comprehensive quality assurance works, evaluating the application against predefined quality benchmarks and refining the code based on testing feedback.


The deployment phase is a critical step in the CSDLC, bridging cloud application delivery’s development and operational aspects. It requires careful planning, automation, and monitoring to transition from development to production successfully.

There are such core activities related to this stage:

  • Configuration management
    Configuration specialists establish the application settings and parameters according to the targeted environment, ensuring compatibility and optimal performance. That involves managing dependencies, environment variables, and other configuration aspects.
