Service Oriented Architecture (SOA)
The third party services have been using or not using compatible with each other for
utilizing application and overcoming limitations for utilizing Simple Object Access Protocol
(SOAP). This has been a messaging protocol that helps programs for running in the operating
system and communicate with each other using XML.
SOA has been a style software design in which services are provided with the help of
application components to other components in the protocol. Each service of Indian Grocery
Store application has been integrating in similar stage that creates SOA. The SOA o the system
has been given below:

Cloud Computing Delivery Model and Platform
Cloud Computing
As commented by Dumas et al. (2013), Cloud computing has been helping in delivering
computing services over the internet. Cloud computing has ben providing several opportunities
over the internet. It has become a huge paradigm for accessing data and information from the
cloud server. It has been helping in providing proper resources that are not limited to networking
communication, hard drives, computing devices and other software applications. There have
been some examples of cloud services including online data storage facility, email and social
media.
Features:
Device Independence: Cloud devices has been device independent and have been accessed with
the help of any web browser.
On-demand: User has been able to manage could service based on their needs.
Broad network access: It helps in network connection for functioning and operating.
Maintenance: Cloud vendor helps in maintaining the system that helps customers not to worry
about their services.
Performance: Cloud services have been provided by various IT giant performance has been
away for improving and expectation crossing.
Types of Cloud Computing
Cloud computing can be divided into three types that are mentioned below:

Private Cloud: Private cloud has been helping in meeting internal needs of
organizations. It has been securing all types of cloud as it can be implemented with internal
firewalls of companies. It has been controlling and accessing to the internal of the organization.
Public Cloud: This has been the most popular type of cloud. Public cloud facilities can
be accessed by other parties and third vendor. It has been less secure and vulnerable to security
risks.
Hybrid Cloud: Hybrid cloud has been the combination of private and public cloud. This
type of cloud has been implemented for availing services related to both private and public
cloud. This type of enterprise have been implementing cloud services of third party vendors with
private cloud. Security of this type has been helping in maintaining services with public and
private cloud. It has been providing more security to data and information stored in the cloud
database.
Cloud Computing Service Models Representations
Service Model: There has been three ways by which Cloud Computing have been
offering services:
Software as a Service (SaaS): SaaS has been defined as software as a service that have
been providing as a system to the customer. There have been subscription done based on
monthly, quarterly and yearly charges for software service being provided. There have been
some free mode of storage and services provided to new users of cloud. The use of different
mode of subscription helps in maintaining a keen approach in the development of the
organization.
Features of SaaS:

 One – to - many delivery model
 Commercial software online
 Application Programming Interfaces (API) for connecting with other applications
 Management of Central administration
Justification for using choosing SaaS: SaaS software as a Service has been central hosting
software that has been provided in the form of pay and go service. The grocery store might easily
scale up their business by scaling up services provided to the customers. The cist has been
reduced with the help of using SaaS services. It helps in providing expensive software at low
cost or on rent. Thus help in minimizing initial infrastructure cost of the store in the market.
There are some more reasons for using SaaS:
 Least implementation time
 Low setup cost
 Limited training has been required
 Every application related function will be handled and managed by the vendor
 Fast scaling according to needs
Platform as a Service (PaaS): As commented by Röglinger, Pöppelbuß and Becker (2012),
PaaS has been helping in maintaining a keen approach in providing platform as a service. It has
been providing platforms for developers on order to create their applications by using advance
techniques and tools quickly. PaaS has been similar to SaaS on the basis of providing services
online. Both the service model have been helping in providing software and platform as a service
over the internet.
Features of PaaS:

 Online user interface for coding, designing and implementing
 Multiple concurrent user architecture
 Billing and subscription management
 Service for building, deploying, testing and maintaining an integrated environment
Justification for using PaaS: The PaaS model has been guaranteeing free operations from
the commonplace administration during arranging for group and support from work with the goal
and concentrating on developing programs.
Infrastructure as a Service (IaaS): As commented by Chang (2016), IaaS has been helping
in providing Infrastructure as a service in the cloud environment. It has been providing storage,
servers and networking devices. IaaS has been providing best options for various organizations
instead of buying these hardware and infrastructure. Users can get these resources on their
demand.
Features of IaaS:
 Allowing for scaling resource based on the requirements
 Resources have been providing as service
 It consist of multiple users on single powerful piece of hardware
Justification of using IaaS: The IaaS model has been providing fast and secure services that
also helps in permitting small companies for managing their frameworks within any place and
time. Various businesses have been finding IaaS easier to be used in their workplace.

Google Cloud Computing Delivery Model
Google Cloud Platform is a package of cloud computing services provided by Google.
Google Cloud Platform (GCP) has been running on same infrastructure that has been utilized by
Google products including Gmail, YouTube, G-maps and search.
Google Cloud helps in providing many tools and quality features for helping in building a secure
infrastructure as a service (IaaS) and public and private utilize of cloud service.

Following are the features of Google Cloud:
 Computing: It has been a fully managed application development platform including
compute engine, app engine, container registry, cloud functions and container engine.
 Networking
 Storage: Scalable, consistent, high performance object storage, reliable and database of
applications.
 Big data management
 Machine Learning
 Developer tools like cloud in Android studio, Eclipse and Intellij.

Some benefits of cloud systems are as follows:
Flexibility: It has been scaled up and down as per requirements of the system.

Automatic software updates: The server has not been responsibility of the customers
and supplier have been responsible for keeping on updating technology for keeping competition
in the market.
Security: As the data is stored online at some off shore secure location data is never lost.
All the current cloud service provider take security of the platform very seriously, thus makes it
more secure.
Easy Access: Cloud computing has been able to access from anywhere across the globe
with the help of internet.
Increased collaboration: Internet can be accessible from anywhere across the globe
using internet connection.
Backup and recovery: Most cloud service providers have policy for backing up data
every 3 days and supporting recovery in case of failure in case of problems.
