Let’s delve into how you can start building a robust architecture:
What is product architecture?
Product architecture refers to a roadmap detailing the digital product’s (or software) features, functions, and relationships. In the initial phases of a project, a mapping tool actively guides the process and project team. The team draws it with the assistance of schematic and block diagrams.
Although used as a mapping tool, it doesn’t necessarily mean that the end result would remain the same. It serves as a sort of roadmap, providing a foundation for what the team is going to build.
When drawing the architecture, the project team keeps three things in mind: the product’s modules, components, and schematics. The project team develops each module to perform its own function while ensuring that it works in conjunction with the rest of the modules.
Each module has its own sub-functions that act as the product’s components. In the end, it’s a matter of mixing and matching different components to achieve the desired end product.
This article will discuss the specifics of software product architecture and the steps involved in creating a successful one for your product.
Types of product architecture
The project team can subdivide product architecture into different types based on several factors. It is either based on its network pattern or how each component contributes to the overall product function. In the former, when it concerns SaaS (software-as-a-service) products, the backend-to-frontend architecture is the most common type. While in the latter, there are two types of product architecture—modular and integral.
In the world of SaaS, the usage of cloud services has become increasingly common. According to a report, cloud and shared architecture will reach 45% of spending by 2025. It makes sense for companies to shift to such products because it helps them deploy apps faster and scale at the pace they need.
Given its extensive usage, backend-to-frontend architecture has become one of the most common product architectural patterns. In this type, for each client application (front end), there is a server-side component (backend). The drawing point of this architectural pattern is that if all the different client interfaces have different needs that rely on the same resources, this would be the most efficient option for them.
The front end refers to the collection of technologies, tools, processes, and documentation to keep the client’s end goals in mind. The back end refers to the code that runs on the server and receives client requests. It also includes the logic that determines what data needs to be sent back in response to the request. The database that stores all the application data is also a part of the backend.
Now that we understand how this core SaaS architectural pattern works, let’s look at how architecture differs based on its contribution to the overall function of the product.
In modular architecture, each product module focuses on one specific task that contributes to the product’s overall functioning. These modules are self-containing, and you can organize each of them to work in conjunction to perform a single function.
The way they work with each other or the relationship between these product features enables the end-service delivery. Considering the ease of flexibility and scalability, more often than not, this is the preferred software architecture type by product specialists.
Different product modules take up various functions in integral architecture, unlike in modular architecture. The main difference is that they are not necessarily in line for assemblies or defined arrangements. Here, the modules work with each other to contribute to the product’s overall functionality despite having overlapping functionality.
The project team designs the components explicitly for the product by creating individual parts, given their nature. Additionally, the layout is less structured compared to the modular patterns. Due to the unique nature of the components, the project team cannot easily switch them out if any modifications are are in need for the future.
Steps involved in creating a SaaS architecture
1. Collect your requirements
The first step in creating your product architecture would be understanding what your client is looking for and their pain points. Evaluate what kind of problems they are looking to solve with this product. Hone in on who the end-user is—your client or their customers. Based on that, you can factor in the need for scalability and flexibility.
Once you evaluate their needs and end goals, ensure its documented and reflected through the creation process. In addition to that, you can also include the information about the kind of resources they have at the moment, the budget for the project, and any other specifics you might need for the designing process.
2. Validate your requirements
It’s important to validate your requirements to ensure that you have the correct information in hand. After consulting your product team, validate the actual possibilities for creating such a product.
The project team evaluates the technical specifications that will be useful for the product, determines the cost, explores if and how the cost can be less , and investigates if there are any similar products available to base the initial model on. Document the validation process to give an overview of the potential roadmap and the decision-making process.
3. Create a product roadmap
You will need to create a product architecture specification (PAS) for this purpose. It’s a document that describes and formalizes a single level of a product’s system hierarchy design. It contains information on defining a single system as a collection of its boundary, inputs, outputs, and subsystems. It also includes the interfaces connecting inputs to outputs passing through its subsystems.
The result is a system identification matrix that briefly explains each system’s existence with respect to its functional requirements. The project team creates the final diagram that illustrates how the entire system interfaces, and they will need to measure and justify each interface eventually.
4. Identify the specifics of your tech stack
The tech stack that the project team chooses will play a significant role in how they create the PAS and conduct and manage the product creation process. To finalize your tech stack, you need to identify the frameworks, languages, data, database, and microservices you will be using.
These are the questions you need to answer:
- What kind of frameworks and languages will you use to code the architecture?
- What kind of data will be stored?
- What kind of applications do you need to store the data based on the data type?
- Where will you keep all your data, and how will your data be managed?
- How can data be retrieved from the server, and which applications would be necessary to use in this case?
- How will your modules (microservices) be connected? How will these microservices be chosen, and how will they communicate?
- Is overall product compatibility a factor or just microservice-microservice compatibility?
Once you can answer these questions, you will know which applications and related aspects will be a part of your final tech stack.
5. Identify deployment process
Once a rough draft of the PAS is created, the next step would be to explain how the product will be deployed. For example, when you consider a SaaS product, ideally, you would build it on top of a PaaS (platform-as-a-service) and then deploy the software.
As they act as a service to run and connect with existing software, this client-server model works best for this product. The project team needs to specify the type of network models that they will use for client-server communication, the approach they will take, and how they will test the deployed products.
6. Create an iteration process
After deploying and continually testing the product, the project team needs to collect feedback from the testing phase and document it. In the document, the issues and potential fixes are detailed. The process of implementing the changes must also be put down.
This ensures that a consolidated document is available for all stakeholders involved. These are the questions you need to document in this case:
- What needs to be optimized in the product?
- Does the product require a pivot in the development phase?
- How do you know which product architecture is implemented?
- Does it do the job in the most efficient way possible?
- If not, how can it be further optimized?
7. Evaluate the outcomes
All the information gathered in the planning process needs to be combined into a single architecture design document. This document consists of an architecture diagram that shows how every component and module connects. It also includes the entity-relationship diagram showing how the entire database is structured.
After this, it is reviewed by senior technical leads (SSEs) and modified based on their feedback. Once the document is finalized, it’s broken into epics, stories, and tasks in Jira. Any iterations required will also be documented, including how to push updates after the application is developed.
Role of product architecture in product development
The key to a successful product lies in the design and development process. It’s true because it affects how the product is developed, deployed, and managed in the long run.
Product teams can reduce their time on the trivial back and forth, optimize their cost savings, and hasten the development process by having a solid product architecture before the development process.
- It helps in assigning roles to different teams based on the activities they have to carry out. By doing so, other teams can collaborate proactively, allowing for seamless collaboration over time.
- It gives the different stakeholders a clear overview of which part of the product contributes to which functionality. It also explains why specific components are being used—helping them justify the product development process.
- It removes unnecessary friction and hurdles in the development process, leading to quicker completion times. These plans also help create a sustainable product free of errors and help teams visualize problems beforehand.
Who is responsible for making it?
Ideally, the entire product and engineering team is involved in the process. Based on the market and client needs, the Product Architect is the ideal person to take the lead on such projects. They create an engineering configuration for review, simulation, and validation of new products.
The team keeps iterating the architecture based on the feedback from their impact analysis to ensure that the final product meets the client’s needs. They are also adept at creating PAS, engaging with the code, and communicating with various collaborators such as scrum masters, product managers, and customer service representatives.
At High Peak Software, we have the Team Leader, Senior Software Engineer, Chief Technical Officer, and Product Managers who handle the creation process. We also involve the Junior Software Engineers to train them by asking them to review documents. Including different stakeholders makes finding loopholes in the product easier and iterating as needed to build an airtight product architecture.
Elements of a software product architecture
There are various factors to consider while creating a software product architecture. Some of them are:
Think about whether the product can scale with time and when the company is growing. If it can, how easy is it to provision and scale?
Depending on the customer’s needs and the company’s trajectory, goals change with time. Any product should be able to meet new requirements, adapt to changing environments, and make future management easier.
The quicker the server responds, the better the end-user experience. The product must be designed so that the end-user doesn’t face delayed response times, and when they do, a fail-safe must be set in place.
Operational continuity is an absolute must in today’s day and age. While 100% continuity might be challenging to achieve, if there is a failure, it’s essential to know how long it’ll take for the system to get back up and running.
Evaluating the amount of data already available in hand and how it will be used to create the product. If there is old data, the question arises as to where it will be stored and is it of any value concerning this project. All potential ideas and estimated workflows can be tracked visually using project management tools, keeping all project stakeholders in the loop.
In this case, the main question is how the costs can be cut down over the planning, development, and testing phase. Can the architecture be altered, so that specific components have dual functions? Other factors include cost optimization for data, servers, platforms, code reusability, vendors, etc.
The most critical part of any product development process. Think about how the current architecture accounts for any potential or existing vulnerabilities in the product. If such vulnerabilities exist, how can they be managed, and would that require additional resources?
