Want to develop a secure mobile app? Read the article by mobile app developers & learn about the significance of mobile app architecture design and development.

1. Why Mobile App
Architecture is Vital for
Mobile App Development?

2. Have you ever wondered which aspects of your life
haven’t been touched by the capabilities of a
smartphone? Aren’t we dependent on this tool for
almost everything right from working, traveling,
shopping, banking to even learning?
Even businesses are embracing mobility to enhance
the efficiency of their workforce. This has led to
tough competition among the mobile app
development companies. As a result, many players
fail to reach their set target.
Often the reason for failure is attributed to the
ignorance of app development companiestowards
one of the fundamentals of mobile app
development – the mobile app architecture.

3. What is mobile app architecture?
Mobile app architecture is a set of techniques
and patterns used to develop fully structured
mobile applications based on industry and
vendor specific standards. While formulating
the app architecture, the procedures that
work on the wireless mobile device like
smartphones and tablets are also taken into
consideration.

4. The mobile app architecture design usually comprises
of multiple-layers within an application comprising of
the following layers:
•Presentation layer – This layer comprises of the UI
components as well as the UI process components.
•Business layer – This layer is formed of business
entities, workflows and business components as
well.
•Data layer – Data access components, data utilities
and service agents together form this layer.

6. Elements to consider before developing
your mobile app architecture
Since building better app architecture is
crucial to the success of your mobile app
development, you would need to keep in
mind the following factors before getting
started with designing your app architecture:

7. Determining the device types
There are different categories of smartphones and it is
very important for you to evaluate the device type and
its characteristics prior to selecting particular app
architecture. You must keep the following
characteristics of the device in mind:
•Screen resolution
•Size of screen
•CPU characteristics
•Memory
•Availability of development framework
•Storage space

8. Wondering why we have to determine the device
type while selecting app architecture? This is
because the features of your mobile app might
have some specific hardware and software
requirements.

9. Considering bandwidth scenarios
It is of utmost importance to keep in mind the
internet network scenarios of the areas your
target audience thrives in. This is because
fluctuation of internet speeds can negatively
impact user experience. Your customers may not
be connected to the internet all the time. They
might even have the intermittent network at
times. Therefore, you must consider the worst
internet network scenarios while building your
mobile app.

10. Consider power consumption and speed while
selecting software protocols and hardware for
your mobile app. Also design your cache
mechanism, data access mechanism, and state
management such that it can adjust to slow
and intermittent internet connection.

11. Defining user interface
When it comes to creating mobile
application user interface design, you can
explore the horizons of creativity with your
distinct style. However, you must remember
to keep the interface as simple as possible so
that users can intuitively interact with the
same. Furthermore, keep in mind that a
jumbled UI could lead to the downfall of your
app.

12. Picking the right navigation method
The navigation of an app is a very crucial aspect
which includes both frontend and backend.
While selecting a navigation method you would
need to bear in mind your customers’
preferences and also your app requirements.
This is critical as it will have a tremendous effect
on user experience. Among many different
navigation methods you must analyze and select
your best fit; some of the popular ones are as
follows:

13. Now, the thing is how would you ensure that your
mobile application meets with the requirements of
your target audience? Well, for that you would need
to follow certain guidelines while building your app so
that it performs efficiently in different scenarios.
•Stacked navigation bar
•Tab controller
•Modal controller
•Single view
•Gesture-based navigation
•Scroll views
•Search driven navigation

14. How to maintain the process flow of your
mobile application?
Usually, your mobile application can be
structured in three different layers as mentioned
above; we would take a look at the guidelines to
be followed for each layer.

15. Presentation layer
The primary focus of this layer is how the application
would be presented to the end user. While designing
this layer, app developers are supposed to determine
the correct client type which is compliant with the
infrastructure. The deployment constraints of the
client should also be kept in mind.
The other prerequisite for designing this layer is
selecting the correct data format and put in place a
strong data validation technique so that your app can
be protected from invalid data input.
Furthermore, our mobile app developers also focus
on decoupling of business logic from the
presentation layer code.

16. Business layer
Logging, caching, validation, security and exception
management are various aspects that the business
layer is concerned with. Our mobile app
developers state that you must separate the tasks
into various categories in order to reduce the
complexity of this layer.
However, they say that using a separate business
layer wherever permissible is the ideal approach of
designing this layer. For different functionalities such
as complex business rules, applying policies, data
transformation, and validation, etc. you must identify
business layer.

17. Data access layer
This layer meets with the application requirements
and facilitates secure data transactions. Therefore,
you must design this layer such that it could scale in
the future as the business requirements change
down the road.
Being an experienced mobile app development
company, we focus on choosing the right data access
technology so that a secure and highly functional
layer could be formed.
You can also use table-based identities to render a
simplified design structure for storing data and
allowing movement of data across boundary layers.

18. All the data access functionalities are encapsulated
inside this layer and it manages all the data
connections needed by the mobile application.
Moreover, it handles all CRUD (Create, Read,
Update and Delete) operations and data sources.
We also implement the least privilege approach in
order to protect any attempt to steal or corrupt
data by safeguarding the data access mechanisms.

20. How to choose the right architecture for
your mobile app?
We have been serving our clients for more than
a decade with mobile app developmentservices.
Here are recommendations from our team
of mobile app developers which would enable
you to choose the right architecture for your
mobile app:

21. If you do not have budget constraint then it is wise
to develop native apps as they provide intuitive
features and performance.
You can also opt for “develop once and run
anywhere” concept but adopt different
approaches. You can either develop a mobile web
app or hybrid app with modest development effort
or go for cross-platform apps using cross-platform
frameworks and provide richer experience while
reaching out to vast range of mobile devices.

22. In case your target audience comprises
of iOS and Android users and your objective is to
deliver the best user experience then Helios
recommends native app development. However, if
you need to build all the other operating systems
including Windows and BlackBerry then cross-
platform development could be a cost-effective
option, yet usability has to be compromised.
You can also consider native as well as web
development to complement each other and help
you better engage your customers and employees.
While native apps render optimal user experience,
web apps ensure visibility of your business by
reaching out to customers with all kinds of devices.

23. Final Words!
By now you might have understood how
critical mobile app architecture is for a successful and
profitable mobile app development. It not only
makes your app secure but also enables it to scale
with your growing business.
Do you follow the entire flow, discussed above, while
designing your mobile app architecture? What is the
most important point, according to you, should be
kept in mind while designing mobile app
architecture? Let’s initiate a discussion!
