Mobile application development: It's simple and easy in the lab, but once your application is deployed in the wild, all bets are open. You need to offer users fast, transparent experiences on low power devices in a wide variety of network environments.
When it comes to creating mobile apps, the uncontrollable behavior of users can lead you down the road to the death of 1,000 cut papers. But by recognizing and avoiding these 5 major pitfalls for mobile development, you are preparing to succeed, from development to deployment, to migration to a significant number of users.
Do not think of the commitment after the download
Congratulations, you have successfully launched your application with the features that prompted the user to download your app in the first place. You should now ask these users to continue using your app in the long run.
The average retention rate of mobile apps (the proportion of users returning to the app within three months of their first session) is only 20%. This is an impressive number: at least 80% of users never use an app after trying it for the first time. The reality is that users have a seemingly infinite range of application choices, and with such competition, any performance problem quickly drives a user roll.
To maintain application engagement, alerts and real-time notifications are relatively easy to implement and extremely powerful to maintain a direct connection with the user. Push notifications, desktop alerts, SMS, email – there are many ways to provide users with one-time information even when their app is not open. Your users have their phone with them all day, every day. You therefore have more than enough to worry about sending attractive messages that interest you.
Do not think early to the global audience
You have built your mobile app for today, but have you built it for tomorrow? This is really where the adage "it works in the lab, but not in the wild" comes in. That your total number of users has grown exponentially and you're suddenly taking charge of thousands (or even millions) of concurrent users, or that your application has remained small but used worldwide, scalability must be a priority. There are two big factors at play here:
- You must ensure the speed and reliability for as many simultaneous users attracted to the application
- You need to ensure speed and reliability for users wherever they are on Earth.
To ensure scalability, you need global coverage and redundancy. Global coverage means multiple points of presence automatically connect users to the nearest data center, so users in Tokyo, for example, have the same low-latency connectivity as users in New York. And global redundancy means there is robust online recovery and recovery of data in your infrastructure – ensuring users always have the latest, most relevant updates, and a point of failure. allows them to instantly connect to the next closest network.
Go monolithic rather than decoupled
The monolithic architecture is self-contained: all the components of the application are interconnected and interdependent. In other words, this approach, which was at the root of the technological revolution, is closely linked. On the other side of the spectrum, modular applications are weakly coupled or decoupled, which means that the application is composed of independent microservices, as well as other independently operating programs. A decoupled architecture protects against failures when changes are made because the risk of failure of other microservices is lower; and when something goes wrong, it's easier to isolate the problem.
For mobile applications, the use of a decoupled architecture allows you to more quickly create more scalable and extensible applications. From a reliability point of view, microservices being isolated, the failure of one service should not have an impact on other services. Failure isolation ensures that your mobile application itself is resilient to unexpected events. If, for example, your push notification service fails, the rest of your application continues to function normally, and since the microservices themselves are individual components, you can easily use another push notification service until you reach the end of your application. your main service is restored. to be operational.
Microservices are also very willing to play with third-party services. When creating mobile apps, you often do not have the time (or, in some cases, the know-how) to create all the features and functions from scratch, but instead choose to integrate the best services, more reliable and trustworthy. The microservices allow you to quickly and confidently deploy complex features such as artificial intelligence or enhance security with development tools to create secure and feature-rich applications.
Make security an afterthought
If she is connected to the Internet, someone will try to hack her. It's not a question of whether, it's a question of when. So when it comes to mobile apps, security can not be an afterthought, whether you're protecting your users' data, the data they send and receive in transit, or your application itself.
Let's look at the data in transit as an example. Think of data in transit as "any message that travels over a real-time data stream." This can be a chat message, an IoT reading, a stock price, or a push notification. data in transit that are really table issues.
AES / SSL / TLS encryption on each message must be included in any mobile application, large or small. And it must be end-to-end, which means that the message is encrypted before it is sent and deciphered once received: it is never unpacked and repacked during transit. Beyond encryption, a refined access control is another imperative: you must be able to grant and revoke read / write permissions to the individual user. By completely controlling who can read – and who can write – data into your mobile application, you dramatically improve your ability to prevent unauthorized access to the application.
Do not make battery consumption and bandwidth a priority
No matter how important your application is: if it quickly depletes your user's battery or consumes a lot of its network, it will look for an alternative.
When it comes to managing bandwidth when creating mobile apps, it's important to recognize that mobile users will not always be connected to a reliable WiFi connection, or even to 4G. Nevertheless, users will often still have to use the application in unreliable or varied network environments – such as in a car, in a tunnel or in any other place with uneven coverage. If your application is designed to run only on the most powerful Internet connections, it will start to perform poorly once tested, which will drive out your users.
For battery consumption, it is imperative to look for where and how energy is used. Some common battery drainers include unnecessary background activity, inefficient refresh applications, and highly localized applications. When choosing an infrastructure or platform to power your mobile application, keep in mind the battery consumption and determine the features that your service provider has to reduce it. Does the platform use efficient data transfer protocols? Does this include things like caching messages? Does this allow you to use a microservice oriented architecture? How the architectural platform provider of their product determines the performance of your product.
Creating mobile apps is not easy, but making the right infrastructure and design model decisions is a guarantee of success – from development to deployment to scaling – become the next step .
