7 Stages or How We Work with Clients for Building SaaS Applications

Suppose you are interested in building a SaaS app from scratch in your partnership with a vendor. In that case, you will certainly want to get acquainted with our cooperation regulations that conform to the Amazon Web Services (AWS) certification.

So, the 7 stages of our cooperation with Clients in building SaaS applications are:

  1. Arrange an Initial Call

    We, the Romexsoft team, ask the potential Client to exchange the key information. From our side, we share our relevant experience and expertise in the area of modern application development on AWS, as well as give information on the services we provide and the terms of collaboration. You, in turn, are expected to share your requirements.
    Output: a follow-up email with detailed steps of our cooperation, including a comprehensive list of specific questions to help you supply us with the further data needed for efficient work.

  2. Collect Requirements

    We shared the most essential information during our initial call. Yet, to allow for discussing all significant questions arising, we will establish and hold consistent communication between experts or stakeholders from your side and tech experts from our side, primarily via emails and further calls.
    Output: clear and accurate understanding of the functional requirements of your serverless application.

  3. Analyze Requirements

    Having received all the necessary data on each of the points vital to the process, our team carefully analyses your requirements so that we can prepare a proposal.
    Output: your business logic requirements and expectations are scrutinized to be later incorporated into a proposal for the development of a secure and reliable solution. It will also provide the most comprehensive overview of the working process.

  4. Prepare the Proposal

    What we prepare and present then is a proposal containing the main aspects of cooperation, such as a draft architecture, timeframes, team composition, estimated budget, etc. It will also include your functional requirements discussed at the need analysis stage. Should you be unsure of some, or lack any, our team will help you establish the indispensable functional requirements the solution is supposed to have. Upon presentation, you will be expected to review and comment on the proposal for us to implement the necessary changes.
    Output: a proposal which is reviewed by the customer and updated according to their remarks and suggestions. Once the updated proposal is once again reviewed and approved by the customer, a contract is drafted.

  5. Build the Software Development Team

    Guided by the project’s requirements, we weigh up factors like the complexity of your request, deadlines, expected expenditure, and other resources to establish a software development team structure and select the experts that possess the necessary competence and skill.
    Output: a right-sized Software Development Team with the best skill set to develop the application that will meet your needs and expectations.

  6. Build SaaS Application

    While developing the solution, our Managed Team sets up the SDLC (Software Development Life Cycle) that plans and tracks the designing, developing, testing, maintaining, and improving the product. As a result, modern app development on AWS is supervised and controlled, with day-to-day project management ensuring the team’s performance and product quality.
    Output: a ready Modern SaaS application (either a web or mobile, or both) that satisfies your demands within time and cost estimates.

  7. Support SaaS Application

    As soon as your application on AWS is developed and deployed, we ensure its steady operation by offering 24×7 AWS DevOps Support. With our assistance, you can focus on your business goals – we will take care of everyday maintenance and support your solution to guarantee the app’s round-the-clock efficiency.
    Output: your application is up, it operates smoothly 24/7, and is broadly available at your target audience’s fingertips.

Why does Modern World Need Modern SaaS Applications?

Modern SaaS (Software-as-a-Service) Applications, continue to gain ground among business tools. Quite sensibly. In this section, you will uncover the reason for their rank-topping technology investment and leading in global market value over the recent years.

SaaS Applications, alias cloud-based software, are applications built with a combination of new architecture patterns, operational models, and software delivery processes. As a web-based model for digital services distribution, it grants access to information through an internet connection, without regard to a type of device or a need for a special software installed, hence it is accessible. At the same time, SaaS Applications customers take advantage of improved security, swift deployment, scaling, and customizing of their business solutions.

The following information will further illustrate why businesses lean toward building modern applications on AWS.

Modern Apps enable:

  • scalability – supporting zero to million users;
  • global availability;
  • managing up to petabytes of data;
  • rapid response in milliseconds.

Why Modern Apps:

  • easy maintenance: less time-consuming and demanding maintenance of modern apps makes room for business matters;
  • agility: microservice architecture at the apps’ core is easier and faster to develop, test, scale, and upgrade at individual components with a lower risk to the application as a whole, thus speeding up innovation and time to market;
  • improved ROI: apart from increased development efficiency, AWS services, such as AWS Lambda or AWS Fargate, prevent overutilization or underutilization of resources as they automatically adjust to the fluctuating workload;
  • enhanced use of resources:  infrastructure resources are built using serverless technologies, as well as containers, purpose-built data stores, and software automation;
  • customizing: most closely tailored to the needs of the customers.

What should you know about the elements of the modern SaaS application?

Modern SaaS applications consist of the following elements:

  • Application architecture – either modular or microservice architecture (API and event-driven).The latter is made up of individual independent components which run every application process as a service. Each of them carries out a single function and so can be updated, deployed, and scaled to comply with the requirements for specific functions of the app catering to business capabilities.
  • Data architecture – purpose-built and decoupled. It allows independent autonomous task performance that brings about easier data storage and management in contrast to monolithic databases which might be a single point of failure.
  • Software delivery – automated. Through continuous integration and continuous delivery, automation generates a repeatable motion to accelerate the software delivery lifecycle. In this way, code of higher quality and speed can be produced more frequently.
  • Operations – as serverless as possible. No server management is one of the most significant merits of the serverless approach which contributes to automatic scaling, built-in high availability, and a pay-for-value billing model. Prioritizing automation and opting for serverless means focusing on business matters instead of heavy lifting.
  • Management, security, and governance – run through guardrails expressed in code. Guardrails are preventive or detective processes that reduce the occurrence and the blast radius of undesirable application behavior. Such mechanisms ensure further smooth and fast operation with no threat to the business.

Benefits of modern application development:

  • Faster to market
    Accelerated software lifecycle combined with offloading operational overhead leads to quicker construction of new features by Development teams. This, in addition to automated test and release processes that minimize error rates, produces market-ready solutions faster.
  • Increased innovation
    With a modular architecture, modern SaaS apps are at much lower risk as changes are integrated at the level of their components. They can also be conducted faster, encouraging developers to experiment.
  • Improved reliability
    Any issues that arise can be evaluated and addressed in real-time on account of automated testing and consistent monitoring at every stage of the development lifecycle. This is why modern serverless applications are increasingly reliable at deployment.
  • Reduced costs
    With offloading infrastructure management, the apps’ maintenance costs are lower. On top of that, modern applications decrease the cost of over-provisioning or paying for idle resources as they follow a value-based pricing model.

Why Modern Apps on AWS:

  • capabilities offered at any level or transit states to comply with even the strictest security and regulatory demands;
  • the most complete portfolio of containers, serverless technologies, and developer tools to build and run applications;
  • better security, regulatory compliance, performance, and scaling features if compared with any other provider for modern application services;
  • endless possibilities for strategic development;
  • high scalability and flexibility.

How We Build Modern SaaS Applications

Software Development Life Cycle (SDLC), also known as Software Development Process, is a methodology followed in the development of any solution. As a detailed framework dictating and governing each stage and each task of the process, SDLC ascertains the release of the high-quality products in due time with the most effective resource management. While it may seem complicated in certain regards, we will further describe and illustrate the AWS modern web app development step by step to render a comprehensive understanding of responsibilities and roles at each given stage of crafting the product.

Phase 1. Discovery & Design

Whatever the product may be, properly completed initial stages of detailed estimations and planning are crucial to its success. Transferring the idea to the SDLC, they correspond to the phases of Discovery and Project Structure Setup, respectively.

The Discovery Phase stipulates the following responsibilities:
1) Requirements collection – all requirements are documented by an Architect, a Project Manager (PM), and a Business Analyst (BA);

2) Architecture Design – Requirements are analyzed by the Architect; the deliverable is an Application Architecture Document;

3) Team Composition – a Delivery Manager (DM) and the Architect cooperate to achieve an Optimal Team Composition.

The Project Structure Setup includes the upcoming:

1) Project Setup – the Delivery Manager and the Project Manager setup Collaboration tools and SDLC processes while the Architect and a Team Leader work on the structure and common pattern creation;

2) CI/CD Setup – a DevOps engineer builds a basic AWS environment, Continuous Integration (CI), and Continuous Delivery (CD) process;

3) Team formation and on-boarding – the Architect, together with the Project Manager, interviews applicants and communicates with the Client.

Discovery and Design Phase of building SaaS Application

Phase 2. Development

The Development phase is the part corresponding to the actual coding process according to the requirements outlined in the documents during the preceding phase in order to reach the goals set within the resources allocated.

The Development phase proper encompasses:

1) Completed Team Composition – the Delivery Manager cooperates with the Project Manager to lead the team onboarding and knowledge transfer;

2) Application Development:

  • the Project Manager and the Team Lead compose the backlog (a prioritized set of tasks needed to achieve a strategic outcome);
  • the Team works within the SCRUM model (an ultimate approach to process organization whereby it is divided into sprints with consistent progress tracking and feedback) to deliver the Project features being supervised by the Architect and the Delivery Manager;
  • a Quality Assurance Engineer (QA) monitors each sprint’s quality.

3) CI/CD evolving:

  • the DevOps engineer’s objective is to keep CI/CD aligned with development needs;
  • Separated AWS environments are designed for development and production use.

Phase 3. Production

The focus in this part of the SDLC turns to the implementation of the Project, its optimization, and appropriate maintenance.

The Production Phase comprises:

1) Release to Production – the Team finishes the MVP, and propagates to the Production AWS environment through CI/CD;

2) Production Monitoring and Maintenance:

  • the DevOps Team designs Runbooks;
  • a monitoring system is set up;
  • 24/7 System operators react to emerging alerts and use the Runbooks to resolve them.
