MOBILE CLOUD COMPUTING SYSTEMS AND SAAS SCHEMES 2
Mobile cloud computing is a technique in which mobile applications are normally built and
hosted using cloud computing technology. It provides a platform in which mobile apps are
deployed to mobile devices. This technology provides a basis in which resources such as storage
and also processing takes place outside of the device and are always availed through the cloud.
This technique tends to support a wide range of devices.
This technology of computing has incorporated some of the models such as SaaS and
MBaaS as categories of cloud computing. SaaS as a model is where a third-provider will host
applications and avail them to users and developers so that they can make use of them whereas
MBaaS as a model provides mobile app and web developers a way of linking up their apps to
backend cloud storage.
With the use of Saas, individuals or organizations have an easy time to maintain the systems they
own because everything is taken care of by the third- party vendor(s). They will access these
resources via Web or API. There is no need for those interested to install or download any
resource into their devices.
An example of a mobile app which has embraced the use of SaaS technologies is Netflix
Mobile App. Netflix provides media services. It was founded in 1997 in California and it has
grown at an alarming rate and latest reports indicate that in 2019, the service provider had over
150 million subscriptions worldwide. It entirely enables people addicted to movies, TV shows,
Music, trends to name but a few to stream those services at the comfort of their homes (Raja,
Chitra & Jonafark, 2018). The buffering is very quick and when it comes to streaming the quality
is high. It provides a wide variety of content.
The following are some of the benefits the app has benefited from using mobile cloud SaaS:

 The usage is scalable.
 Compatibility across the devices
 No costs incurred on hardware.
 Anything in cloud can be accessed from any location
 The updates are very automatic.
 Applications can be customized to suit user’s needs.
Netflix App will enable you to stream or download anything you are interested to watch. The
advantage of it is that, there is no limit in what you want to watch as long as you have
subscribed. All of these are stored on the provider’s hardware so as to ease the burden of a user
looking for storage. Netflix has also put into consideration security when streaming. The only
drawback is that it has taken the company to embed in every device (Jimenez, Diaz, Lloret &
Romero, 2019).
When it comes to the architectural view, Netflix data is hosted at Hadoop Distributed File
System (HDFS). At the moment, all data for Netflix is stored at Amazon Web Services (S3) in
which their architecture is centered. The migration has enabled Netflix to have extra space to
install several virtual servers and store huge amount of data. All data which emanates from
streaming using laptops, Macs, Televisions is stored in the platform. The platform is known to
provide availability this is due to bucket versioning which can preserve, recover and stock data.
So data loss hardly happens (Lakhwani, Kaur, Kumar & Thakur, 2018).
Amazon also offers Elastic MapReduce which provides an API that provisions and execute
Hadoop Clusters on which you can run diverse Hadoop jobs. The use of S3 also has a way of

spinning up various Hadoop clusters which are in a position to access same data from the data
warehouse (Usman, Jan,He & Chen, 2018).
These are the benefits of S3;
i. The capability to manage and synchronize different Hadoop clusters that read data from
the same source.
ii. Scalability.
iii. The granular versioning proficiencies.
