Software developers are increasingly embracing microservices architecture, a server-side approach characterized by self-sufficient, interconnected services. Microservices architecture permits different teams to independently develop various services. It ensures the main workflow remains uninterrupted - a degree of adaptability seldom found in other architecture models. Moreover, the emerging concept of multi-runtime architecture is drawing increased interest. In this blog, we’ll delve into both microservices and multi-runtime architectures, highlighting their advantages and drawbacks when contrasted with traditional monolithic architecture. What Exactly Are Microservices? Microservices represent a software development technique where applications are constructed as a suite of small, independent services, each dedicated to a particular function and communicating through well-established APIs. This strategy facilitates application scaling and accelerates the development cycle.  The advent of microservices architecture was driven by the need to overcome the constraints associated with traditional monolithic architectures. Traditional monolithic architectures are often rigid and less scalable, failing to satisfy numerous contemporary demands. In a monolithic framework, different processes are tightly integrated and function as a single cohesive unit. So, a demand spike in a specific process requires scaling the entire system. Since the application grows and its codebase enlarges, it becomes progressively more challenging to add new features or improve the monolithic application. In addition, monolithic systems pose a greater threat to the overall application’s uptime due to the interdependence and tight coupling of processes, where a fault in one process can lead to significant, widespread issues. Why You Should Use Microservices Architecture? Now, let’s delve deeper into some key features of microservices architecture! #1 Modularity Central to the microservices approach is modularity. This entails breaking down a software application into smaller, self-sufficient units, each tasked with a distinct function or responsibility. Known as services, these units function independently and interact with others through APIs. This modular design boots adaptability, allowing for individual services to be modified or expanded without affecting the whole system. #2 Decentralization Microservices embody decentralization in terms of both data handling and control. Contrary to the centralized data management in monolithic structures, microservices enable each unit to possess its data logic. Furthermore, microservices foster more robust and flexible data handling. Decentralized control allows teams to autonomously oversee their specific services, which accelerates development timelines and minimizes the need for extensive coordination. #3 Scalability Scalability stands out as a key benefit of microservices. Given their autonomous nature, services can be scaled out (by multiplying instances of the same service) based on demand. This feature of microservices is essential for managing fluctuating workloads and ensuring the application remains performant under increased demands. #4 Independent Deployment Microservices architecture permits the independent deployment of individual services. Consequently, enhancements, fixes, or new functionalities can be rolled out to a particular service without necessitating a pull application redeployment. This facilitates a more streamlined continuous deployment process, lowering the risks and costs associated with deployment activities. > Related: Top 10 Mobile App Development Mistakes You Must Avoid in 2024 What Does Microservices Architecture Consist Of?

In today’s digital era, mobile apps have emerged as the foremost platform for businesses to engage with their customers. Have you ever heard about “in-app notifications” before? Flutter, an open-source UI toolkit developed by Google, has established itself as a transformative force in mobile app development amidst a sea of programming languages and frameworks. An important element that greatly influences user engagement and the success of businesses within mobile apps is the interaction of in-app notifications. In this article, we will explore the advantages of incorporating in-app notifications in apps built with Flutter and how they can fuel your business growth. What are In-App Notifications? In-app notifications refer to messages or alerts that are delivered directly within a mobile app to its users. Unlike traditional push notifications that appear on the device’s home screen, in-app notifications are displayed while the user is actively using the app. These notifications can take various forms, such as banners, pop-ups, overlays, etc. They are designed to provide relevant and timely information to the app users. It serves multiple purposes, including: User engagement: In-app notifications help to keep users informed, engaged, and connected with the app by delivering personalized and targeted content. This can include updates about new features, promotions, discounts, and relevant news. User retention: By sending reminders, recommendations, or personalized offers, in-app notifications can encourage users to revisit the app and continue using it. As a result, this can help improve user retention rates, and increase the chances of converting users into loyal customers. Conversion and monetization: In-app notifications can be used strategically to drive conversions and monetization within the app. For instance, it can promote special offers, and discounts, encouraging users to make purchases. > Related:Top 10 App Development Companies in Vietnam for 2024 Some Benefits of In-App Notifications for Flutter Apps So now, the question is “How does Flutter improve the functionality and effectiveness of in-app notifications?”. The answer lies within its core attributes, namely cross-platform compatibility, customizability, performance, and cost-effectiveness. Cross-platform compatibility: With Flutter, you can build apps that are compatible with multiple platforms, including iOS, Android, and even the web.

If you’re a Python developer, you might be familiar with the concept of “pipelines”. But what exactly does it mean? And what benefits do pipelines offer? In this blog, we’ll delve into the concept of pipelines in Python, and the advantages they bring to your code in terms of readability and efficiency. What are Pipelines in Python? So, what are pipelines in Python? For those who don't know, pipelines serve as a systematic arrangement of continuous operations or functions designed to handle data. The output of each operation serves as the input for the subsequent one, creating a continuous flow until the ultimate result is achieved. Conceptually, pipelines can be visualized as a sequence of interconnected pipes, facilitating the smooth flow of data from one pipe to another, undergoing various transformations or manipulations occurring throughout the process.  Solution 1: Creating a Loop An approach to do this involves creating a loop that iterates the list and applies each operation one by one, storing the intermediate outcome in a new list. For example: This code works, but it’s not very clean or efficient. It makes three new lists, taking up memory and making the code harder to follow. Plus, it involves writing four loops, which can be a bit tedious and error-prone. > Related: App Development for Your Business - Detailed Guidance Solution 2: Use a Pipeline A smarter way is to use a pipeline. Think of it like a series of connected steps. Instead of creating extra lists and loops, you can link the operations together. To do this, we can use the built-in map and filter. These functions apply a given operation to each element of a group without creating extra lists. There are also the sum and len functions that calculate the total and length of an iterable, respectively. Here’s an example to illustrate this idea: This new code is shorter and simpler than the previous one. It avoids creating extra lists or loops and makes it clear how data moves from one step to the next. However, it’s not super easy to read because it uses nested map and filter calls, which might be confusing. Solution 3: Use the Pipeline Function A better way to make the code more readable is by using the pipe function from the toolz library. The pipe function takes an initial value and a sequence of functions. It then applies each function to the result of the previous one, making it easier to understand the overall flow of the code. For instance: This new code is easier to understand and more elegant compared to the old ones. It clearly shows the sequence of operations that are applied to the data, and it doesn’t use complicated nested calls or extra lists in between. The pipe function makes the code look like a series of connected steps, where the data smoothly goes from one action to the next. Why You Should Use Pipelines? Pipelines are used for several reasons, providing a structured and efficient…

In today’s interconnected world, where websites and web applications play a vital role in our daily lives, ensuring security and protecting user data is of paramount importance. One crucial security measure that helps safeguard user information is the Same Origin Policy (SOP). In this article, we will explore the concept of Same Origin Policy, its necessity, implementation, and some of its limitations. So, what is Same Origin Policy? SOP refers to an important security policy aimed at preventing websites from attacking each other. It is a fundamental security concept implemented by web browsers to regulate the interaction between web pages or web applications from different origins. An origin is defined by a combination of the protocol (such as HTTP or HTTPS), domain, and port number. The SOP acts as a virtual barrier that prevents scripts and other web resources from accessing or manipulating data across different origins.  For example, you can consider the following URL: To illustrate, suppose you are browsing a website, “www.mywebsite.com”. According to the Same Origin Policy, any JavaScript code running on that webpage is restricted from making requests or accessing data from other domains, like “www.anotherwebsite.com”. This restriction ensures that sensitive information, such as cookies or user credentials, cannot be accessed by malicious actors. > Related: Single-Page Application (SPA): Pros and Cons in Web Development Why SOP is necessary? Protect against Cross-Site Scripting (XSS) Attacks: XSS attacks occur when an attacker injects malicious scripts into a trusted website, allowing them to steal sensitive user information or manipulate the content of the webpage. The Same Origin Policy prevents the execution of such malicious scripts by restricting their access to resources from different origins. Prevent Cross-Site Request Forgery (CSRF): CSRF attacks involve tricking users into performing unintended actions on a web application. The Same Origin Policy prevents unauthorized websites from making requests on behalf of the user to another website, mitigating the risk of CSRF attacks. Isolate User Data: By enforcing the Same Origin Policy, web browsers ensure that sensitive data, such as cookies or local storage, is accessible only to web pages from the same origin. This isolation prevents unauthorized access to user data, enhancing privacy and security. Some limitations of Same Origin Policy While SOP is an essential security mechanism, it does have certain limitations:  Cross-Domain Sharing: The SOP restricts access to resources across different origins. While this provides security, it can also hinder legitimate use cases where cross-domain sharing is required, such as embedding content from external sources. Third-Party Dependencies: Modern websites often rely on third-party scripts and services. These scripts might require access to user data or interact with resources across origins. However, due to the Same Origin Policy, such interactions may require additional security measures, like CORS, to allow controlled access. Subdomain Restrictions: The SOP considers subdomains as separate origins. Therefore, scripts running on "subdomain.example.com" cannot access resources from "example.com" unless explicit cross-origin permissions are established. To sum up, the Same Origin Policy is a vital security mechanism implemented by web browsers to…

These days, there are numerous websites developed for business purposes with the ultimate aim of meeting customers' demands fulfilled. As web development places greater emphasis on user interaction and customization, single-page applications (SPA) have gained significant popularity as a preferred method for presenting content and fostering user engagement. So, its merit is to make it a popular way to develop websites for many enterprises. What are Single-Page Applications (SPA)? A single-page application is a type of web programming, it can be a web app, or it can also be a website with the ability to bring the smoothest, best experience to users like when they are operating on a Mobile App. It loads a single document and updates the existing page with new data from a web server instead of reloading each page separately from the beginning. Examples of Single-Page Applications Netflix Built on the React framework, Netflix is an online streaming platform with movies and films. Under the base of the SPA approach, there is no interference in the viewing experience; moreover, it can stream a huge quantity of data to simultaneous platform users. Basically, the process goes from the user's request making then loading new data in the browser within its suitable speed. Gmail There is no need to refresh the page when clicking on messages in your inbox. All the necessary data is loaded from the server in one go, providing a seamless user experience. It's also a typical example of a single-page application. Spotify This page contains various sections, including playlists, albums, artists, and search functionality. As you interact with the application, such as searching for songs or navigating between different sections, the content dynamically updates on the same page without requiring a full page reload. What is the difference between SPA and MPA? Architecture: SPA consists of a single HTML page that is initially loaded and subsequent content updates are dynamically fetched and rendered on the same page using JavaScript. MPA, on the other hand, consists of multiple HTML pages where each page represents a separate view or functionality. User Experience: SPA provides a smoother and more responsive user experience since the content updates happen in the background without page reloads. MPA may introduce slight delays and interruptions during page transitions due to the need for full-page reloads.   [caption id="attachment_9134" align="aligncenter" width="443"] Difference between SPA and MPA[/caption] Pros and Cons of Single-Page Application Advantages of Single-Page Application Better UX The key merit in web development is being more seamless and less time-consuming. SPAs use client-side routing, enabling fluid navigation without needing full page reloads. Additionally, the seamlessness also comes from the quicker load and the more interactive appearance. Its interface includes interactive elements, and when users click, the single-page application responds by rendering accordingly and instantly. Mobile-friendliness This is the exclusive advantage of single-page application. SPAs can leverage technologies like Service Workers or local storage to provide offline capabilities, so it's rather accessible even when they are in an offline or low-connectivity environment. Also,…

Agile and Waterfall are two very popular software development models used in corporations and technology companies these days. So, what exactly are Agile model and Waterfall model? The main difference between these two models? Which one is better? AMELA will help you understand these two models in this article! What is The Agile Model? What is The Waterfall Model? Agile Model [caption id="attachment_9122" align="aligncenter" width="1864"] The process of the agile model[/caption] It's a method of building and developing software projects. This method significantly shortens development time, repeating tests in a short period of time, thereby developing the project quickly. Waterfall Model [caption id="attachment_9124" align="aligncenter" width="927"] The process of the waterfall model[/caption] It is a cyclical loop method. The method helps deploy a software project sequentially and thus the project development team only moves to the next development or testing phase if the previous step is completed successfully. Difference Between the Agile Model and Waterfall Model [caption id="attachment_9126" align="aligncenter" width="472"] Differences between agile and waterfall[/caption] + Agile allows customers to request changes to requirements or additional specifications at any time during the development process. Waterfall must make changes to specs and other specification requirements before development begins. + Agile can provide services at each iteration so it will be fast. As for Waterfall, it only allows providing services after completing all processes, so it will take more time. + Documentation is not required in the Agile development model; however, if it is an effective method of conveying information, documentation should still be created. In contrast, with the Waterfall development model, documentation needs to be created for each process and connected to the next process. Additionally, documentation also serves as proof of the project once the entire process is complete. + Agile requires regular testing for each implementation, while Waterfall requires testing only during the testing phase. + In Agile development, each engineer will perform his or her own development work without having to have a specific area of expertise; but with the Waterfall model, it is imperative that one person is in charge of each process. + The Agile method helps you learn practically through iterative developments. Because you are responsible for all rounds of development, you will have more experience and be more adaptable in many areas. Waterfall development is more about using people with expertise and experience, so training/recruiting human resources is relatively easy. + Agile can improve the process for each iteration; If it's not okay this time, it's completely possible to improve next time. However, with Waterfall, we can only see the points that need improvement after the project is completed, so we can only draw and apply experience to the next projects. Which One is Better? Each model has different advantages and disadvantages, it is important to apply the appropriate model depending on each project case.
