What is serverless architecture?
How is the serverless model different from other prevalent cloud computing models?
What are the opportunities and obstacles of serverless applications?
Is my business going to benefit from the serverless computing model?
Well, this article answers all the aforesaid questions! So, let’s commence.

What is serverless architecture?

Serverless architecture refers to a software design pattern in which a third-party service hosts the applications; so that the developers need not engage in the task of managing the server software and hardware. This approach is also known as serverless computing as the app logic gets implemented in an eco-system wherein servers, OS, and virtual machines are not visible. This doesn’t mean that servers are not used at all. The app logic is executed on an OS that uses physical servers. But, the difference with other cloud services is that; here the service provider wholly takes up the responsibility of infrastructure management and so the mobile app developer can focus only on writing codes.

Categories of Serverless Applications:

FaaS (Function as a Service/Feature as a Service), the serverless model enables developers to build, run and manage the app functionalities; without having to create or maintain the infrastructure needed for developing and launching the app. The first FaaS service provider was AWS Lambda by Amazon, followed by several others like Microsoft Azure, Google Cloud Functions, etc.
PaaS (Platform as a Service), another category of cloud computing, bears similarity with FaaS as they too hide servers from developers. But, unlike FaaS this service runs one server process continually for receiving external requests. The app is scaled by booting up more server processors, for which the developer is charged and so the scalability is visible to the developer.
BaaS (Backend as a Service), is another prominent model which addresses the cloud-computing requirements for the mobile and web app developers by offering them a unified means of connecting their apps to cloud computing services. As such, BaaS automates the development of the backend for the web and mobile and also manages the cloud infrastructure. This enables the mobile and web app development companies to only focus on the frontend part of the application.

Serverless Applications: Advantages

Reduced Administrative and Infrastructural burden
The hassle of managing servers passes on to the vendor, resulting in the following benefits for a mobile and web app development company.
  • Firms need not spend a huge amount on the hardware or hire engineers for maintaining that hardware.
  • More time and resources can be dedicated to creating and improving customer-facing features.
  • Developers have the flexibility of crafting and scaling the apps as required; without having to worry about the constraint of server capacity.
Cost-efficient Pricing Model
In traditional server-full architectural setups, developers have to figure out in advance the amount of server capacity needed; based on which the company purchases the capacity whether or not they end up using it. However, serverless setups follow the “pay-as-you-go” policy which means the vendor charges the company only for the amount of server space they use. The code runs whenever the serverless application needs backend functions and gets automatically scaled up whenever required. Also, provisioning is precise, dynamic, and happens in real-time. As FaaS charges a fraction of the price per request, a start-up can build an MVP at minimal cost without having to pay huge bills for lesser traffic.
Quicker Deployments and Updates
The serverless model eliminates the tasks of uploading the code to servers or engaging in any backend configuration for releasing a fully functional app. Hence, developers can speedily upload bits of code and launch a new app. As the app is a collection of functions provisioned by the service provider, rather than being a single monolithic stack; developers can either upload the entire code at one go or upload one function at a time. This ability speeds up the tasks of fixing, patching, or updating the app without any need to make changes in the entire application.
Latency Reduction
Since the app does not get hosted in the origin server, it becomes possible to run its code from anywhere. As such, the app’s functions can be run on servers that are close to the end-user depending on the vendor selected. This strategy reduces latency as the requests coming from the user need not travel a long way to reach an origin server.
Inherent Scalability
Serverless applications are capable of scaling automatically with the increase in the number of user base or usage. If a function requires to be run several times, the vendor’s servers will start, run and end them as required using separate containers. This provides the ability to handle a higher number of requests effectively as compared to a traditionally structured app.
Serverless Applications: Downsides
  • As the vendor fully controls the operations, a firm has to abide by their rules. For instance, if your app is set in Lambda it’s not easy to port it to Azure. This concern applies to coding languages as well. Presently only Python and Node.js developers have the flexibility to choose between the prevalent serverless options.
  • FaaS tools involve a steep learning curve despite the availability of comprehensive documentation.
  • Companies need to split their monolith into microservices for painlessly migrating to a serverless model.
  • Debugging and troubleshooting become challenging as serverless apps use traditional tools.
  • This model is great for short real-time processes but an additional function needs to be called if the task takes longer. Traditional approaches fare better for indulging in extended duration operations.

Bottom line

Serverless computing best suits start-ups and small businesses. But, if your company has a well-established workflow, it’s important to weigh the pros and cons before making a decision.

These staggering numbers are a glimpse of how rapidly consumers are adopting mobile apps. Businesses all over the world have realized the potential of a mobile app and are heavily investing in this arena. But to be honest, the success rate of all apps is not so impressive. Though, smart applications like Facebook, Pinterest, Instagram, Messenger, etc. have succeeded in garnering immense popularity. Therefore, before you proceed to hire mobile application development services for crafting an outstanding app, you must know which elements to include in a mobile app.
So, curious to know about the requirement of building smart mobile apps? This blog will solve your queries as it gives you a peek into the key structural elements that are essential to know during the mobile application development process for creating smart and successful mobile applications.

Key Elements to Consider While Creating a Smart and Successful Mobile App

Mobile Application Development Process
Understanding the End-goals and Knowing the Target Audience
It is of utmost importance to thoroughly gauge the objective behind developing a mobile app for your business. Besides, understanding the target audience is essential to meet their expectations through the app and ensure that the app becomes lucrative. Demographics like age group, income status, occupation, gender, interests, location, what devices they use, etc. of the target audience are helpful too. Depending on these criteria, you may decide whether you want to integrate relevant features like GPA, social media, payment integration, analytics, etc. in the app.
Well-structured Architecture
The mobile app architecture should be well-structured so that it integrates suitably with the existing records. This will ensure quicker downloads, prompt responses, easier interactions, effortless installations, faster screen transitions, etc. in the long term. So, you need to choose the right platform, technologies, and tools as per your project requirement to shorten the development process and make the app architecture robust and scalable. The benefits of a well-structured mobile app architecture are as follows:
  • High code reusability for speeding up the developmental cycle.
  • Lesser efforts are required by developers for implementing changes in a changing environment or business policies, etc.
  • Increased portability for apps, components, databases, APIs, and services.
  • Easier testing and fixing of issues.
Also, a good mobile app architecture ensures that the enterprise mobile apps are mostly deployed on web servers or cloud services based on the connectivity, network latency for speedy accessibility, and bandwidth.
Ease of Navigation
An app with poor or complex navigation is bound to fail. Such an app makes it difficult for the users to search for anything in the app and leverage its services to the fullest. So, they might instantly switch to your competitor’s app. Hence, it is vital to have user-friendly navigation in the mobile app. The app should be clutter-free. For most apps, simplicity of use works much better than having a complicated app.
Adhering to UI Creation conventions
While creating the app’s user interface, a mobile app development company should consider certain UI elements and adhere to specified UI conventions. This helps to maintain consistency with other apps present in hand-held devices. For example,
  • Android has set certain UI creation guidelines concerning aspects like menus, icons, over viewing widgets, task designing, etc.
  • Apple too has set specific guidelines on how developers should develop the UI of iOS handsets like formatting content, hitting of targets, touch controls, text size, contrast, spacing, high resolution, etc.
A Good UX Design
A good UX design satisfies the fundamental objectives of a mobile app which are brand recognition, gaining customer loyalty, attracting traffic, and generating revenue. The reason is users prefer applications that are easy to use, are inspiring and mood-uplifting, convenient, make them feel smarter, enable faster task execution, and offer flexible payment options. Remember that tons of competitors may be offering a similar app as yours and the users will choose your app only if your UX design stands apart from the rest.
Maintaining Screen Size Consistency
The screen size and resolution are not the same for every device. Hence, while building smart mobile apps the developers need to make sure that the screen is consistent and responsive across various mobile app devices. Besides, the UI, as well as the graphics, should be scalable.
Considering Ergonomics
A majority of modern smartphones come with touch screens. Therefore, the apps must be designed in such a manner that the users can easily operate them on their touch screen handsets. For this reason, the mobile app developers have to visualize how the users will hold the smartphone and place their fingers while using an app. For example, the apps crafted for touch screen handsets usually have content, menus, and selectors at the top portion of the screen. Additionally, aspects like zoom pinching, gesture advantages, backward swiping, refresh pulling down, etc. need to be designed as per touch screen requirements.
Device Performance Considerations
Device performance considerations like size of the app, battery/processor usage, etc. cannot be neglected in the process of mobile application development.
  • Size of the mobile app: the size of the app matters especially when the end-users have slow internet and less storage capacity in their device. An app with a simple and well-thought design consumes less space and will keep the device’s RAM and CPU free. This ultimately enables the app to be fast and responsive.
  • Battery/processor usage: while designing the app, it is necessary to consider the fact that some apps consume high battery, especially gaming apps, or similar complicated apps. So the app must be designed in a way that it doesn’t consume too much battery and processor.
Explicit App Content
For every app, the mobile app development company has to make sure that the buttons are labeled appropriately, technology terms are explained aptly, there are guidelines provided for the app to work, etc. The content must be clear, precise, and to-the-point. Also, it must be up-to-date and have authentic information that guides the users well.

Wrapping Up:

Smart mobile apps are in demand and so harnessing this demand will fetch you immense profits. But, for creating a smart and successful mobile app, you need to consider the aforesaid elements. The mobile app development should be carried out by following the best practices and processes and combining a tinge of innovation and creativity. Because a few app development mistakes can cause gigantic loss to the business owners / entrepreneurs.
