What are microservices?

Microservices are small, independent software components that work together to form a larger application. Each microservice handles a specific function and can be developed, deployed, and scaled separately. In a broader sense, it’s an architectural approach that divides the backend into several independent services.

What are microservices for eCommerce?

eCommerce microservices are small, specialized software components that handle specific online store functions on the server side of the application. They allow businesses to update specific functions without disrupting the entire system, scale individual services to meet varying demands, and easily integrate new technologies.

Why are microservices a good architectural solution for eCommerce?

First, they allow the store to grow easily – you can scale only the part that needs it, without impacting other parts of the software. Second, they make updates simple. Third, they help stores stay current. As new technologies emerge, you can plug it in without rebuilding everything.

Are microservices suitable for all eCommerce businesses?

While beneficial for many, microservices may be overkill for very small or simple online stores.

Importance of Front-End DevelopmentWhy does front-end development matter so much for any business in the digital age? The answer is quite simple. It’s the first point of contact between the company and its user; it’s the face of the working processes; it offers visual appeal and ease of use; it’s often the first thing that comes to mind when thinking about the specific company. A solid front-end is much more than just making your site look good. Under various circumstances, resorting to the services of a reliable front-end development provider brings different advantages. Companies from various industries and economic sectors benefit from the front end in different and often subtle ways. So, today, we will try to find out the importance of front-end development for your industry and how you can take a competitive edge from it.Defining the front-end developmentBut first, let’s explore front-end development itself. Front-end, or client-side development, shapes the visual and interactive elements of websites or applications that users interact with directly. This part of the application is traditionally called a user interface. The front-end development process typically involves coding and designing the user interface across various devices and browsers. This field blends technology and creativity to deliver seamless digital experiences. In a broader sense, front-end development also includes quality assurance and post-update maintenance, encompassing all aspects of the process of building a visual part of the application with which the user interacts directly.Technical specificationsThe entire process of client-side development covers a broad range of tools, languages, and best practices. Here are some important points we need to understand about front-end development:Programming languagesHTMLHyperText Markup Language (HTML) defines the structure and layout of the content located on the web page. It’s the “basic language” of the web.CSSCascading Style Sheets (CSS) manage the visual presentation and design, including layouts, colors, and fonts. It makes your website look good.JavaScriptJavaScript (JS), one of the most popular programming languages in the world, enables the interactivity and dynamic elements we see on modern web pages. JS allows dynamic updates, multimedia management, and animated graphics on the modern web. This language also goes paired with numerous front-end frameworks that significantly simplify building sites and web apps.The role of front-end developmentAt the same time, front-end development is a bridge between your website or application’s digital interface and the user experience it delivers. The visual elements, design, and interactivity of the software solution crafted by front-end developers directly impact not only the visual perception of your website or application but also your search engine ranks, overall user journey, security of the software, and many other aspects critical to your business success. So, here are areas directly impacted by the quality of your front end:Importance in user experience (UX)A good front end directly enhances and creates a positive user experience by improving the usability, accessibility, and overall pleasure of the interaction between the website/product and the end user.Importance in Search Engine Optimization (SEO)When it comes to websites and web-based applications, efficient front-end code helps boost SEO rankings by optimizing the website’s speed of response for both desktop and mobile versions, which are key metrics for most search engines.PerformanceGood front-end developers focus on optimizing the speed and responsiveness of a site or app, reducing load times, and improving interaction readiness.Brand identityStrong branding requires consistent visual elements, typography, and color schemes, all of which also depend on UI and front-end development services.Integration of third-party servicesThe level of challenge you will face when integrating third-party tools and systems, such as payment gateways, social media platforms, and analytics tools, also depends on the quality of front-end development services. A well-developed front-end connects to the backend well, eventually.SecurityPoor front-end security measures are frequent companions of outdated and poor graphical user interfaces. Effective front-end development automatically ensures robust security measures.Why front-end development is important in different industries?For a better understanding of why the front-end is important, let’s check some real-world use cases. Whether your industry relies on a strong website where users buy some products or obtain services (for instance, the retail industry or fintech) or merely use the website for marketing purposes (for instance, consultancy or real estate), the impact of user-friendly design and an engaging user experience is undeniable. The front end’s crucial role is that it directly impacts how users interact with your business, whether it’s building the front end from scratch or front-end migration or rewrite.In every industry, the front end serves as the digital facade that either welcomes potential customers or turns them away. Therefore, denying the importance of front-end development for any business is difficult. However, there are several industries that benefit from well-crafted user interfaces the most.We have previously written an article about the benefits of front-end for the real estate industry.Retail/E-commerceE-commerce, as well as e-commerce software solutions, has changed significantly lately. If you recall how online shops looked like at the beginning of the 2010s, the importance of front-end developers will become self-evident. In the retail and e-commerce sector, front-end development directly impacts sales by providing a compelling, easy-to-navigate shopping experience. Advanced features like dynamic product filters, quick-view modal windows, and smooth checkout processes minimize obstacles between discovery and purchase. E-commerce benefits immensely from client-side services like UI modernization, responsive design, and front-end development for headless CMS, a popular solution in the e-commerce domain. Such improvements are vital for keeping pace with the competitive digital marketplace, where the ease and enjoyment of the shopping experience can directly influence customer loyalty and sales volumes.Fintech/BankingBesides back-end development, which is obviously key for fintech, front-end development in fintech and banking directly impacts how users manage their finances online. A decent front-end (including a mobile app) ensures that complex financial and personal information is presented in a user-friendly way, enhancing user engagement through intuitive interfaces for banking transactions, investment management, and personal finance tracking. Secure, accessible, and easy-to-use front-end designs play a pivotal role in building trust with users who handle sensitive financial data, making it easier for them to perform transactions confidently and securely.Tourism and HospitalityIn some ways, the tourism and hospitality industry resembles e-commerce. Although not all tourism websites and web apps have booking and payment options, good visual appeal still enhances the customer’s journey from discovery to booking. The importance of the front-end development process for tourism and hospitality is revealed in interactive maps, virtual tours, and streamlined booking interfaces that work flawlessly on various devices. Similar to other industries, an effective front-end boosts user engagement and conversion rates, but in contrast to others, here, it also converts interest into bookings.Read more
Software Development Pricing ModelsEveryone looking for software development services, sooner or later, faces a critical choice in selecting a suitable pricing model. Depending on the particular situation, choosing the suitable model may involve various factors. How complex is the project? What is its duration? Does it require a specific level of adaptability? Are you looking for a development team to build a product from scratch or just a few external developers to strengthen your existing in-house team? Is your goal cost control or flexibility? Does the project need room for change? Actually, the matter of choosing a suitable pricing model when seeking custom software development services is way wider than it may seem at first glance. This decision certainly cannot be taken lightly, as the selected model can significantly impact long-term business strategy and the overall success of your project. A rightly chosen model can streamline project management, align financial planning with project goals, and ensure a successful outcome that meets both budget and quality expectations. On the other hand, a misaligned pricing strategy can lead to budget overruns, scope creep, or unsatisfactory results. So, what is the right choice for you? Let’s explore the topic together!Introduction to Software Development Pricing ModelsSoftware development is a complex and multifaceted field that requires careful planning and execution. At the core of any software project lies the pricing model, which dictates the financial structure of collaboration between the client and the development team. These pricing models cater to varying needs, complexities, customization levels, project duration, and dynamics of the development process. Furthermore, they set the tone for such development aspects as project management, risk allocation, cost predictability, and expectation setting. This integral part of project planning and execution plays a key role in ensuring the success and sustainability of the software solution.Let’s look at a few prevalent examples. One of the most common pricing models in software development outsourcing is the fixed-price model. Without going into too much detail (we’ll come back to each particular model a bit later), this model is characterized by a predefined scope of work and a set price agreed upon before the start of the project. It makes it suitable for projects with well-defined requirements and stable scope of work. However, compared to alternatives, this approach can be less flexible and may not easily accommodate changes or unforeseen development aspects during the project. Another popular option is the time and materials model, which charges clients based on the actual time spent and resources used on the project. This model offers greater flexibility and is generally considered a good choice for projects with flexible requirements that are expected to evolve. As the industry continues to evolve, so do the pricing models, adapting to new project methodologies, technology trends, and market demands. Lately, the list of software development pricing models has been enlarged by several other options, such as hybrid pricing models or options like a dedicated development team model. Each of the models mentioned above has its own strengths and limitations. Understanding these characteristics is crucial for both clients and service providers in selecting the model that best aligns with the specific needs, goals, and context of the project.Understanding the time and material pricing model The time & materials model (T&M) in software development is characterized by noticeable flexibility and adaptability. Under this model, clients pay for the actual time spent by the development team as well as the materials (or resources) used in the project. This approach is commonly applied when the full scope of the project cannot be accurately estimated at the outset or when it is expected to evolve and develop over time. The T&M model allows for a more dynamic interaction between the client and the development team, as it can easily accommodate changes in project requirements, expected functionality, technical specifications, features, or priorities.One of the key aspects of this model is its billing structure. Clients are typically invoiced regularly (for example, monthly) for the hours worked and resources used. This particular method requires meticulous record-keeping and transparent communication to ensure clients understand what they are being charged for. ProsThe primary advantage of the T&M model is its high flexibility. This flexibility allows for easy adaption to changing requirements, which is ideal for projects where new market trends or technological advancements may influence the direction of the project. In the T&M model, clients benefit from continuous and active involvement in the development process. This close collaboration ensures that the final product aligns more closely with the needs and preferences, enhancing overall satisfaction. Also, this model typically offers a higher level of control over the project for the client than other pricing models for software projects.Another advantage of the T&M model is its capacity for efficient resource allocation. Since billing is based on actual hours (multiplied by hourly rates) and materials used, it encourages a more efficient work approach, potentially leading to optimized use of resources and time. Moreover, compared to the fixed-price model, developers are not pressured to rush to meet a fixed price point, which can sometimes lead to cutting corners.ConsAlthough T&M offers flexibility for the developers, the lack of a fixed deadline or budget cap can sometimes reduce the sense of urgency to complete the project swiftly. The total cost of a project can escalate drastically, making it challenging for clients to plan financially. The T&M model also carries the risk of scope creep, where the project’s scope gradually expands beyond the initial parameters, often leading to extended timelines and increasing the overall costs.Furthermore, this model requires clients to be actively involved and vigilant in project management, which can be resource-intensive and may not be feasible for all clients. Another significant concern is controlling costs, as there is a potential for workers to log more hours than they really spent. Certainly, without strict management and clear communication, there’s a risk of expenses exceeding initial estimates.What do you pay forBy choosing the time and material pricing model, you pay for the actual hours worked and resources used, ensuring that you invest in what is directly needed for your project’s evolving requirements. This model also accommodates flexibility in project scope and direction, allowing for adjustments and refinements based on ongoing feedback and development insights.When to chooseThe T&M model is particularly well-suited for the following situations:MVPs, experimentation, and prototyping;Projects where the scope is not clearly defined or is expected to evolve.Innovative projects involving new technologies or untested solutions.Projects in dynamic industries where flexibility is essential.Situations when the client prefers to be actively involved in most aspects of the development process, allowing for regular adjustments and refinements.Exploring fixed-price modelThe fixed-cost pricing model, also known as fixed-price, is characterized by a predetermined cost for the entire project, agreed upon before the project starts. In contrast to the previous model, T&M, fixed-price is well-suited for projects with well-defined scopes and clear deliverables. Under this arrangement, the service provider and the client agree on a specific set of requirements, timelines, and the total cost of the project. Fixed-price contracts are often distinguished from other software pricing models by predictability in terms of budget and scope. In this model, the responsibility for delivering the project within the agreed budget and timeline falls on the service provider. This approach requires thorough initial planning and analysis to ensure that all aspects of the project are well understood and accounted for. Once the project begins, changes to the scope or requirements typically result in contract renegotiation and potential expenditures changes. The fixed-price model is less flexible compared to other models, but it provides a clear roadmap for project completion. ProsThe fixed-price model offers the significant advantage of budget predictability. Clients know exactly how much the project will cost upfront, allowing for straightforward financial planning and eliminating concerns about escalating costs during the project.This model promotes efficiency and discipline for the service provider, as they are motivated to complete the project within the agreed budget and timeline. This focus often leads to a well-organized and streamlined project execution process.Additionally, the fixed-price model minimizes the need for constant client oversight. Since the project scope and deliverables are defined at the outset, clients can expect to receive the agreed-upon product without the need for continuous involvement or decision-making.ConsThe fixed-price model’s rigid structure can be a major downside, particularly if project requirements are not thoroughly understood from the start. This lack of flexibility makes it difficult to accommodate changes or updates without renegotiating the initial contract, often leading to additional costs and delays.This model also carries the risk of reduced quality, as said before, as service providers might cut corners to stay within the fixed budget. The emphasis on cost and deadline adherence can sometimes overshadow the focus on delivering the best possible product.Furthermore, the fixed-price model places a significant portion of the project risk on the service provider, which can lead to conservative approaches in project execution and potentially higher initial quotes to cover unforeseen challenges.One of the most unobvious yet straightforward disadvantages of this model is that many decent service providers try to avoid it at any cost. This avoidance often stems from the risks associated with fixed budgets and strict project scopes. Service providers may hesitate to commit to a fixed price due to concerns about underestimating the project’s complexity.What do you pay forWhen choosing this model, you pay for certainty and simplicity – you are essentially purchasing a defined package of services for a set price, agreed upon before the project begins. This model ensures you know the exact cost upfront, making financial planning easier. When to chooseProjects with well-defined scopes and specifications.Projects with limited budgets and strict deadlines.Short-term projects as well as small-sized projects where the deliverables are clear and unlikely to change.Situations where the client prefers a hands-off approach and wants to minimize involvement in the day-to-day management of the project.Dedicated team modelAlthough a dedicated team model is not exactly what is typically considered to be one of the software development pricing models, it is still a popular approach used in outsourcing, particularly for long-term collaborations. In this setup, the client hires a team of professionals exclusively assigned to their project. This team functions as an extension of the client’s in-house software development team, working closely with them to achieve the project’s objectives. The dedicated development team is usually selected based on the specific skills and expertise required for the project, ensuring a high level of alignment with the project’s needs.This approach offers a blend of flexibility and control, as the client can directly manage the team and adjust its composition as the project evolves. The model is especially beneficial for large-scale projects or those with evolving requirements, as it allows for seamless scaling and adaptability over time.ProsThe dedicated team model offers exceptional alignment and integration with the client’s project goals and company culture. This profound integration results in a team that is highly attuned to the specific needs and nuances of the project. Such an approach fosters effective and efficient collaboration.This model provides a high degree of flexibility in managing the project. Clients can scale the team size up or down based on project requirements, ensuring that the right skills are available at the right time, which is particularly beneficial for long-term and evolving projects.Moreover, having a dedicated team ensures consistency in the quality of work. The team’s familiarity with the project over time leads to increased efficiency, reduced ramp-up time for new features, and a steady output of quality deliverables.ConsOne significant drawback of the dedicated team model compared to T&M or fixed-price is its higher costs, particularly when it comes to smaller or short-term projects. Maintaining a team exclusively dedicated to one project can be especially expensive when specialized skills are required for a specific development field.The model also demands substantial client involvement in terms of management and oversight. This requirement can be resource-intensive and may pose a challenge for clients who lack the time or expertise to manage an external team effectively.Additionally, setting up a dedicated team often requires a considerable initial investment of time and effort, both in assembling the right team and integrating them into the client’s processes and culture. This upfront investment can delay the actual start of the project development work.What do you pay forWhen choosing the dedicated team model, you pay for the exclusive expertise and focused attention of a team specifically assembled for your project. You are investing in a group of professionals who are deeply integrated into your project, aligning closely with your goals and processes. The billing in a dedicated team pricing model is typically based on the number of team members, their hourly rates, and the duration of their engagement, often with a monthly fee structure.When to chooseLong-term projects with evolving requirements where continuous development and upgrades are anticipated.Large-scale projects needing a wide range of specialized skills and consistent team involvement.Situations where you have an in-house team, but you need to strengthen existing resources with external expertise quickly.Cases when development requires a deep immersion into the context or specific aspects of your in-house culture.Hybrid pricing modelsWhen it comes to hybrid software development pricing models, these approaches usually combine elements of traditional pricing models, such as T&M and fixed-price, with individual project circumstances. A typical hybrid model (also known as a mixed pricing model) is designed to balance the flexibility of T&M with the predictability of the fixed-price model, catering to the unique needs of various projects. In a hybrid model, certain aspects of a project might be billed at a fixed rate, such as initial stages or clearly defined deliverables, while others, typically those involving more uncertainty or requiring agility, are billed on a T&M basis. This combination allows for better cost control while retaining the flexibility to adapt to changing requirements and unforeseen challenges.The hybrid model is highly adaptable, making it suitable for projects with mixed levels of uncertainty. For example, the initial phase of a project, with well-defined deliverables, can be charged at a fixed rate, providing cost predictability. As the project progresses into areas with less clarity, the T&M component can accommodate the evolving scope and requirements. This flexibility is particularly useful for complex, innovative projects where the full scope cannot be accurately determined upfront.ProsThe mixed model balances the risk between the client and the software development company. It offers predictability for budget planning with its fixed price component. Yet, it retains flexibility for unforeseen changes through time and material aspects.This model is also highly adaptable to changing project requirements. In this sense, the hybrid model takes all the best from traditional pricing models for software development: it accommodates scope adjustments without renegotiating the entire contract. This adaptability is crucial for evolving or innovative projects.Furthermore, clients typically gain more control over their budget with the hybrid model. They can allocate funds more efficiently, focusing resources on uncertain project areas. This approach often leads to better resource utilization and overall cost savings.ConsSince we are talking about the combination of T&M and fixed-price models, different parts of the development process may inherit from these models such issues as complexity in management, potential scope creep, and challenges in initial estimation.Due to its dual structure, the mixed model can make financial forecasting and budgeting a bit more complex. This complexity arises from trying to anticipate costs in a model that is more intricate than dealing with either a purely fixed-price billing or a purely time and material model.Additionally, measuring performance and progress can be more challenging. The distinct methodologies for tracking and evaluating the fixed price and T&M components can lead to inconsistencies in performance assessment, making it hard to gauge overall project efficiency and progress accurately.What do you pay forIn a hybrid model, you pay for the predictability of certain project elements through fixed pricing while also covering the dynamic aspects of development on a T&M basis. Billing is typically a combination of fixed fees for specific deliverables and hourly or daily rates for the ongoing development phase. Also, mixed model payments are often billed on a monthly basis.When to chooseIn situations when neither fixed-price billing nor T&M pricing strategy suits your software development project.Of course, this is an ideal choice for projects where certain aspects are well-defined, but others are expected to evolve.For complex projects with phased deliveries, such as projects planned in phases, where early stages can be fixed priced, and later phases billed on a T&M basis. Such situations typically happen when the nuances appear after the first development stages.Factors affecting software development costsIn the software industry, the overall development cost is influenced by a multitude of factors, each interacting differently with various pricing models. Here are some of them that should be considered for effective planning, budget, and risk management.Tight deadlines can drive up costs in any kind of software development. However, in the case of a dedicated team model, it will be especially severe, as you need to spend a significant period of time immersing developers into the team.Advanced or niche technologies can increase costs, especially in the T&M model, when these technologies weren’t discussed at the outset.Developing for several platforms raises costs, especially in hybrid models, where each platform might add unpredictability to the T&M component.Regular changes or revisions amplify costs, especially in fixed-price models, where each change requires contract renegotiation.In Agile-driven T&M and dedicated team models, iterative cycles can lead to increased costs due to frequent reassessment and realignment of project goals.In the T&M model, encountering technical challenges can escalate costs due to the need for additional time to resolve these issues.In a fixed-price project, incorporating multiple languages and localization can be expensive if not included in the original project scope.Best practices in selecting a pricing modelSelecting the right pricing model from the very beginning of any software development process is an important factor for the overall success. First, begin with clearly defining your project, the target market, and who your customer is. Choosing a proper pricing strategy means thoroughly understanding the project specifications, requirements, scope, and potential risks. Research the market, what customers are willing to pay, and what they value in products or services like yours. Consider the purchasing power and price sensitivity of our potential customer base. Based only on these answers, you will start to get the picture. Additionally, check the following factors: Access project complexity and duration: Determine the complexity and estimated duration of the project. Larger projects might be better suited for T&M or dedicated team models, while simpler projects could work well with a fixed-price model.Consider development methodology: Agile methodologies might favor a flexible model like T&M, accommodating changing requirements. A fixed price could be more appropriate for projects with well-defined requirements and outcomes.Analyze direct and indirect costs: Factor in all costs related to the project, including direct costs like developer wages and indirect costs like overheads and tool licenses. It helps in setting a price that covers costs and ensures profitability.Value-based pricing considerations: If your software offers unique value or innovation, consider value-based pricing. This aligns the price with the perceived value to the customer rather than just the cost of development.Competitive analysis: Look at how similar products or services are priced in the market.Pricing flexibility and scalability: Be prepared to adjust your pricing model as the project evolves.Legal and ethical compliance: Ensure your pricing strategy complies with industry standards and legal requirements. In some cases, external developers can’t be the best choice, so think about a dedicated team model.Clear communication and transparency: Transparency in pricing builds trust and can lead to a better relationship between the client and the software development model. In this case, you increase your chances of building customized billing relationships that will tailor your project’s specific needs.Performance tracking and adjustment: Regularly track the performance of the development process. Be prepared to make adjustments based on these performance indicators.Read more
