Cloud Solution / Computing Vendors
Presently, there are three major cloud -based web services. Those are:
1. Amazon Web Services (AWS)
2. Microsoft Azure and
3. Google Cloud Platform(Software Testing Help, 2018)
First, let us consider AWS (Amazon Web Services) and why it is rated as top in cloud computing
and best provider of cloud based solutions worldwide. These are the six best features that are
present in Amazon Web Services which makes it the best among all others.
 Easy to use – AWS is designed in such a way that the user can use the application with
ease and provide vendors, ISVs to quickly and also securely host the application. The
application might be an existing one or it may be a new SaaS (Software as a Service)
based application. Users are provided to use management console and can also use web
service APIs in order to access AWS’s application hosting service or platform. And, all
these are well documented (Amazon Web Services, 2018).
 Flexibility – AWS will allow its vendors to choose or select any type of operating system,
any type of programming language, databases and application platform as per need. AWS
provides virtual environment in which the software and services can be loaded which are
dependent on the application. This feature will help in migrating process with ease and
also helps in preserving the options of the old application and build new solutions on top
of it.
 Cost-effective –AWS charges only for the power consumption of the computer, storage
and the other extra services that the user uses. And this comes with no contract basis.

 Security groups – By using copy to new feature, it is very easy to create new security
group. This helps while they are working in identical environment but with different
security functionalities (Muppala, 2018).
 Resources events – This feature is utmost important to track the changes that are been
done over the time period, they need to be monitored for backup facility or rollback
facility.
 Scalable and high performance –Elastic load balancing, auto scaling helps the application
to scale up and down which depends on the demand. With the best infrastructure that
AWS provides, a user has flexibility to use data and services on demand basis.
 Healthcare domain – AWS has high level of services that can be utilized in health
domain. For example: genomics, biotech & pharma will be provided with healthcare
domain having much more diverse functionalities that can be used.
 Security –AWS uses end-to-end approach for security reasons and also to harden AWS
infrastructure. This includes operational, physical and software measures.
Second, Microsoft Azure:
 Azure search – This feature allows the user to search in any web-based application.
Considering the web application that is used by doctors and patients to retrieve, write or
read patient details, if the data are too big, then we need a functionality that brings all the
information based on the search terms (Crabtree, 2018).
 Azure machine learning – Machine learning is again one of the key player in modern era.
Machine learning helps to mitigate complex software problems and helps in producing
