redhat.com 2INTRODUCTION
The intersection of cloud and mobile technologies has been disruptive, overturning traditional
business models and putting users at the center of market demand. Mobile applications offer
an engagement model that lets users access and create a wide range of data—such as images,
video, text, location-based information, and more—through ever-present smart devices.
Ubiquity and scale have made cloud computing indispensable to the management, security,
storage, and on-demand delivery of this data. In addition to providing the engine for managing
data use and generation, the cloud supports agile, platform-based technologies, freeing
developers from infrastructure concerns to focus on creating innovative apps. Cloud computing
has ushered in a new era of app development that creates competitive differentiation based on
speed and scalability.
In this e-book, you’ll learn about using container technologies in mobile app development,
as well as the combined power of mobile technology, cloud technology, containers, DevOps,
microservices, and application programming interface (API)-led integration. Find out how
cloudnative mobile apps offer a key example of the principles of modern app development using a
powerful, enterprise-grade container platform.

Traditional enterprise applications tend to be large, self-contained, and multi-featured, with
complex user interfaces and functionality. They are usually developed using heavyweight
languages and approaches, often compiled into formats that are unique to a specific operating
system. These monolithic applications are built gradually to well-defined specifications and
are rolled out in scheduled implementations, usually under the control of an organization’s IT
department. As a result, they have long development cycles.
Mobile development has had a significant impact on how applications are developed, deployed,
and managed. In contrast to traditional enterprise apps, mobile apps are more lightweight
and agile, with functionality typically focused on a relatively narrow business use case. These
applications offer a simple user interface and a compelling user experience. Mobile apps
require data from backend systems be available securely and in real time. These apps are
subject to almost-continuous, iterative updates based on user feedback and evolving business
requirements.

CONTAINERS are a technology that packages apps with their entire runtime environment—use technical
including all dependencies, libraries, and configuration files needed to run these apps—to provide approaches to
isolation and abstraction from the underlying infrastructure. Containers provide an effective

from monolithic from a developer’s laptop to a test environment, from staging to production environments, or from
a physical datacenter machine in a datacenter to a virtual machine in a public or private cloud.architectures to

management requirements.
WHAT ARE MICROSERVICES?
MICROSERVICES describes an architectural method of developing distributed software systems
organized around business capabilities and priorities. It has become the preferred means
of creating enterprise applications for many developers. A microservices approach involves
developing applications as a suite of lightweight, modular services, where each service runs a
unique process and communicates through a well-defined mechanism to serve a business need.
Using this approach, each service can be deployed, tweaked, and redeployed independently,
without compromising the application’s integrity or requiring redeployment of the entire
application. Microservices are designed to handle failure. If one service has an issue, the client
lets its neighboring services continue functioning while the affected service is isolated and
repaired.
Microservices are also highly suited to evolving models where developers cannot fully anticipate
the types of devices that may access an application in the future.

Mobile has influenced five significant approaches to application development that play a role
across wider enterprise software development and delivery models. They have been instrumental
in the evolution of Platform-as-a-Service (PaaS) and, more recently, containers and container
orchestration technologies.
1 FROM TRADITIONAL TO MODERN APPS
Mobile and cloud technologies have prompted a shift in focus from technology to people.
Users are at the center of mobile innovation, influencing both business and technology. Smart
devices have revolutionized customer engagement, streamlined core business processes, and
modernized employee workflows, leading to new revenue opportunities and improving operational
performance.
SUCCESS STORY: MOBILIZING THE FIELD FOR FASTER EMERGENCY RESPONSE
As tech-savvy mobile and social media users, field workers often initiate or influence the
creation of simple yet powerful mobile apps. For example, an app was created and deployed
