HYBRID CLOUD ARCHITECTURE FOR METASOFT LIMITED
Introduction:
Cloud computing is one of the most important and widely used computing techniques used in
the world toddy in different organizations. It is also known as hybrid cloud computing because it is a
hybridization technique that is used to integrate public as well as private cloud architectures to give a
common solution to all the data storage related as well as other concerns within an organization. When
or more public cloud architectural networks are merged with the traditional in house server and storage
systems, it results in the formation of a hybrid cloud infrastructure. Hybridization in cloud computing is
extremely important in today’s world due to the different risk factors associated with the traditional
computing and data storage techniques. It eliminates different risks associated to data storage and
other risks. IN other words, cloud computing is the future of organizations when every business related
tasks can be remotely and will ease the working operations of all organizations.
This report will study the case of a company called MetaSoft Ltd, which is a software company
headquartered in Australia and operates in New Zealand as well. The company is looking forward to
incorporate a cloud architecture within the organization. The company is planning to close rather
update the traditional working techniques and infrastructure in the Melbourne site. They are planning
to replace the old infrastructure in Melbourne with a hybrid cloud infrastructure and most updated
technologies like they presently have in their Sydney site. Through this, they are planning to increase
flexibility within their working business operational tasks as well as effectively make it beneficial for the
customers as well. The following report will highlight the different cloud infrastructures that can be
implemented within the company and the different aspects such as its risk factors, advantage and
disadvantages.

Proposed architecture for a hybrid cloud:
Firstly, the reader must be aware of what a hybrid cloud infrastructure means. A cloud
computing architecture is nothing but the different network components and their sub components,
which are essential for carrying out the computing tasks within an organization. These different
components consists of working platforms, which are front end, example fat clients Fernando, (Loke &
Rahayu, 2013). It also consist of mobile and portable devices as well as thin clients and back end-
working platforms, for example servers and hard disk drives. The architecture of a cloud network also
consists of the internet, over which data can be transmitted across different devices even across
different geographical locations (Arora, Parashar & Transforming, 2013).

Architectures to be incorporated:
1. Microsoft Azure: Metasoft Ltd, which is a software company, wants to update the entire
infrastructure in its Melbourne site and wants to get it replaced with all the latest technologies
and cloud infrastructures that are presently present in its Sydney office. They want to
incorporate cloud architecture in order to achieve higher rate of availability (HA) within the
organization using cloud architectures such as Microsoft Azure, which is widely used and comes
with a number of advantages. It should be incorporated due to its low cost and the other
corporate benefits that are corporate friendly. Microsoft has come up with this technique for
deploying services and their applications, managing and testing the applications through a global
network, which is widespread. Microsoft consists the data centers storing the data. It provides
features such as software as a service (SaaS), platform as a service (PaaS) as well as
infrastructure as a service (IaaS). Different programing languages from third party vendors are
also supported in Azure (Copeland et al., 2015).
Benefits of using Microsoft Azure:
- It is extremely fast: The deployment speed is extremely fast, as well as its scope of
scalability within operational tasks.
- Improved business agility: The development cycle is obtained much faster without a very
expensive outlay; thereby giving Metasoft limited a much advantageous position.
- Excellent global reach: It can cater to the global needs of the organization since the
company is also present in New Zealand. It has flexible guidelines to operate globally.
Disadvantages of Microsoft Azure:
- Needs careful integration of application: The domains, which get mostly affected, are Third-
party vendors, web services, External storage devices such as hard disk drives, SMTP servers
as well as Payment gateway. These should be properly analyzed before Azure
implementation. Data insecurity can also cause performance lags.
- Staff management: Effective cloud management techniques have to be well explained to
the employees since both cloud and in home servers need to be properly managed. The

application developers should have adequate knowledge about the complexities involved in
the implementation Microsoft Azure.

Amazon web services lambda: Amazon Web Services (AWS) lambda is owned and managed by the
popular ecommerce giant, which is Amazon.com. It provides cloud storage facility of data as well as
other cloud computing operational assistance to the different companies on a paid subscription basis,
which in turn allows remote management of servers. Metasoft can use this platform because of its
cheap costs and corporate friendly features. Metasoft ltd also wants to implement technologies such as
AWS lambda since data security is of utmost concern for the organization, which can effectively be
produced by this cloud platform. AWS Lambda is a kind of a computing platform, which does not make
use of a server. Amazon manages it as a part of Amazon web services. This service runs in response to
different events and it automatically manages different computing resources, which that code requires.

Advantages of using AWS lambda:
- Security: AWS lambda data centers have a very tight 24/7 guard system and a very effective
disaster management system in case of any natural disasters as well as system failures. It
also makes use of a very strict Identity & Access Management (IAM) as well as a cloud audit
Trail feature to monitor what information has been accessed by which employee and at
what time (Hendrickson et al., 2016).
- Flexibility: Amazon machine images (AMIs) are used for self-managing and automatically
scaling which can closely align with the particular needs of Metasoft limited. This is done by
the systems by effective management of the traffic in the networks. Clones are circulated
across different geographic locations in very less time, thereby saving time by preventing the
same tasks to be performed repeatedly.
AWS lambda disadvantages:
- AWS lambda path of data flow and information in a data center is sometimes difficult for the
companies to follow and understand because of its complexities.
- National Products Inc (NPI) has recently declared that the billing structure is extremely
complicated for the client organization to follow where AWS lambda is incorporated.

2. Containers and cloud computing: Containers are applications that offer a packaging mechanism,
which is very logical in nature, in which the different features are easily abstracted from the
working environment where they run. This decoupling feature allows the applications to be
easily deployed in a consistent fashion, even if the target environment is a personal data center,
a public cloud, or even the personal computer of the developer. This technique of
Containerization differentiates the concerns in a systematic way. Logic and dependencies of the
application are the main factors, which the developer focuses on, while Information technology
operations teams focus management as well as deployment without bothering configurations
specific to the applications (Villamizar et al., 2017).
Advantages of Containerization:
- They provide a runtime environment, which is very consistent: they give the developers
the provision to create environments that are predictable as well as isolated from any other
applications. They also include dependencies of software’s that are application specific,
example, specific programming language versions and their run times from different
software libraries. From the perspective of the developer’s, these are all consistent
irrespective of their area of deployment.
- They can be run anywhere: The containers can be virtually run on windows, Mac as well as
linux operating systems in the public cloud as well as the own systems of the developers.
Issues Associated with Containerization:
- Consistent gap in training: It is a very complex technique and needs proper education of
the employees in order to work with them.
- No scalability with applications and unpredictable performance: It consists of gateways as
well as container systems that are distributed– therefore comes with performance issues as
well as scalability challenges.
Risks report of hybrid cloud architecture and the micro services:
There are different risks that are associated to the implementation of Microsoft Azure, AWS
lamb da as well as Containerization, which can be explained below in the following tabular format:

When a company uses Microsoft Azure,
Microsoft reserves all rights to have a

client company just to ensure data
security in an optimum level. This is
clearly stated in the initial agreement that
Microsoft oft signs with the client
company. There is also an issue of
increased cost factors due to metadata
integration in Microsoft Azure
implementation in the companies (Dutta,
Peng & Choudhary, 2013).
The complex design of the containers and
their integration with cloud computing
can cause performance issues as well as
data insecurity. Once implemented, the
outcome is not predictable provided there

companies. Amazon also carries a bad
image in terms of not being able to

government (Hashizume et al., 2017).
There was a recent news of a major
AWS cloud outage all across the world,
which resulted in huge employee as well
as customer unrest, wherein many end
users also had to suffer. This happened
mainly because the employees were not
efficient and trained enough to handle the
situation on an urgent basis due to their
lack of knowledge about the complexities
of AWS servers. AWS lambda tools such as
AWS cli, implementation of Python boto
in desktop as a service technique (DaaS) is
an extremely complex feature of AWS

professionals.

Proposed precautions for information security:
Some of the data security measures that can be incorporated within Metasoft limited can be
described below as:
- Strong passwords should be used in all devices: This is one of the most important steps that
should be incorporated within the company. Strong passwords are characterized by usage of
number and alpha bets that should typically be 8-12 characters long and making use of
special characters and a mixture of upper and lower cases of alphabets.
- Setting up a strong firewall: Again, this very important step can be taken by Metasoft
limited in order to secure the data and the devices that are used by the employees for
business operations. A firewall can be defined as a computer application that blocks harmful
websites from opening up on the computer and other mobile devices that are used within
an organization. Network address translation (NAT) is a networking technique often used by
the system administrators within the organization, which does the work of a firewall.
Pfsense and Fortigate are some of the most popular and widely used enterprise firewall and
antivirus protection systems used in the companies today (Ali, Khan & Vasilakos, 2015).
- Regular application updates to be timely installed in the servers and computers:
Applications especially the security applications keep updating as and when any new
update package are released by the company and it should be ensures by the system
administrators that these updates are properly installed on the systems of the employees. If
an outdated application is used in the cloud systems, it causes performance lags as well as
data insecurity and other issues. Regular security patches and operating system updates
should be made mandatory within the organization so that all employees do that as a
routine task and it should be ensured from the administrators end.
- Diligent back up and monitoring: Regular data backup should be ensured within the
organization to ensure that in any case of a natural disaster or a system failure data loss can
be prevented. Cycles of data backup should be scheduled such as a complete data backup
on a weekly basis and an incremental backup procedure per night. There should also be a
dedicated team that will calculate and analyze the different risks associated to the data and
other aspects of the organization.

- Employee education: All the employees should get adequate training on the working of the
different hybrid cloud architectures within the organization. Without proper education, the
designing will be a major issue because of the complexities of the architectures. In order to
prevent issues during system failures and natural disasters, employees should be enough
prompt to make decisions in such emergencies, for which their proper knowledge about the
cloud infrastructures being used in the company, is necessary.
Changes to Business Continuity Plan
Business Continuity Plan can be defined as the regulatory papers and documents that contains
the organisational plans that the organization has decided to implement in case of any natural disaster
or system failures . On execution of the plan, the organization seeks to continue its normal business
operations and ensure at the same time that the customers are unaffected and their normal business
operation with the customers continue. Metasoft Ltd has come up with its own business continuity plan
through which it expects to shift its working infrastructure to a cloud architectural network. This section
will highlight the migration technique to be incorporated and the systematized back up plan of the data
in order to prevent data loss within the organization. It will also consider a proper service level
agreement with the third party organizations linked to Metasoft private limited, in order to keep them
informed about an y data loss due to an y system failure or natural disasters. Making use of a cloud
infrastructure can ensure optimum data security within the organization. It also helps the organization
to come up with more flexible data backup scheduling cycles (Mill & Park, 2014).
Issues in Resilience
In the process of integrating business continuity plan with a cloud architecture, application of
virtualization can play a vital role. Virtualization is a technique by the virtue of which the usage of al l
physical hardware de vices is eliminated and computers are virtualised across a cloud network.
However, there are certain disadvantages of using virtualization in cloud computing since the virtual
computers cannot be managed and used in a way the physical computers can be managed, resulting I n
data loss an d insecurity an d also performance issues at times (Ahmed & Hossain, 2014).
Cloud architecture implementation within Metasoft Limited will definitely reduce the costs
associated with the physical hardware’s, however more human support and human workforce need to

be recruited in order to efficiently monitor and manage the cloud systems and also the BCP operations
including data backup and other operations within the company.
Disaster Recovery System
This is one of the most important tools for the manager of any department t within the
organization. On its implementation within Metasoft Ltd, the company will look forward to making its
own security patches so that in the e vent of any natural disasters as well as system failures, the
company will be able to recover any lost data (Wallace & Webber, 2017). This technique will be
applicable for all departments across the organization for critical as well as not so important processes.
This technique of data storage is also a very low cost process so the different companies in today’s world
are easily implementing it. As a whole, its implementation benefits the company largely (Pearson, 2013).
Fig 4: Workflow of the business continuity plan (Source: As used by the author).
Backup
Data backup is again a very important aspect of the business continuity plan in which, the
company plans and takes a backup all the data stored in virtual computers in the cloud storage, into in-
house physical hardware computers. This manual method of ensuring that all the data is well protected
and backed up in physical devices ensures that the organization is in no trouble in cases of extreme

emergence such as natural disasters as well as system failures and the data is retained. It is therefore
extremely important that the company have a proper data backup plan in case of an emergency (Menzel
et al., 2013).
Hybrid cloud administration and service level agreement:
Metasoft private limited is a software company, which is looking forward to move its
infrastructure to a cloud architecture. It has planned to update all its working Infrastructure in the
Melbourne site, which still uses older techniques and get them replaced with all the latest technologies,
which are presently there in its Sydney office. They want to be shifted to the usage of a micro service
model such as containers in cloud computing, Microsoft Azure or Amazon web services lambda
technologies. The cloud model should be capable of performing remote server administration, as well as
servers systems and a service level agreement (SLA) management. Two of the most popular
technologies namely: platform as a service (PaaS) and information as a service (IaaS) will be used in the
organization.

Remote Server Administration and resource management
Remotely administering the servers makes use of application programing interface that makes
use of a service portal to manage and work on the servers as well as the hosts (computers, laptops) from
different geographical locations by making use of the cloud computing techniques (Rong, Nguyen &
Jaatun, 2013).
Resource management ensures the below mentioned points:
 Load balancing
 Execution of the server commands (Pahl, Xiong & Walshe, 2013).
 Service level agreement execution (Wang et al., 2013).
 Hybrid corporate friendly environment (Chang et al., 2015).
Service level agreement:
This ensures that the different companies tied up with Metasoft private limited will be
immediately notified about the data backup and other important information in case of any natural
disaster or system failures.

users. The data stored on cloud systems are
only accessible by the users after a user
authentication process based on the “single

organization. These data are carefully
managed and collected to be used by the
users and often it gets extremely difficult
for the cloud service providers like
Microsoft or Amazon to manage such hug e

all the policies are clearly understood by
both parties. The data are stored in a secure

This is the Dalbhanjan and Morad’s Checklist, and it ensures a smooth implementation of all the
important t asks to be taken in to consideration before the implementation of the cloud infrastructure
within the company. The checklist is designed especially for the incorporation of IaaS and PaaS within
the cloud architecture (Hashizume et al., 2013)
SharePoint migration to cloud architecture
Migration Plan
Each organization needs a proper plan for cloud integration. Metasoft private limited will be
using desktop as a service in which a third part company for the remote management of computers, will
provide virtual desktops (Snedaker, 2013). This section will highlight the systematic processes of
incorporating AWS lambda in the workspace.

Step1 –Amazon workspace lambda configuration.
Metasoft limited must first install the AWS lambda workspace in all the computers and servers
within the organization in order to configure the same. Microsoft active directory should be used since a
separate directory for the data storage is required for its implementation. Additionally, a template
should be set up so that AWS lambda can monitor the data and its security on behalf of Metasoft limited
(Zhang et al., 2014). A strong portfolio name and a storage space should be assigned to the AWS lambda
functions. Finally, the product details should be incorporated in the AWS names to b used in Desktop as
a service (DaaS) (Ward, 2016).
Step 2 –ServiceNow setup is to be installed in AWS lambda
Metasoft limited should also seek an IAM permission from Amazon in order to implement the
Amazon web service Lambda operations (Akiyama et al., 2014).
Step 3 – Servicenow validator
A login should be created for al l the users on the servicenow portal for user authentication.
Fig 8: Service now validator of AWS lambda (Source: As used by the author).
Issues in Migration Plan
There are different issues that are associated to the migration to a cloud infrastructure. One of
the biggest challenge is the amount of time required and it causes the important business tasks to be

halted. Data security is again an important concern since the data becomes much more vulnerable to
virus attacks (Barker et al., 2013). It also involves an increased cost and capital investment for the
companies (Rittinghouse & Ransome, 2016).
Conclusion:
From the above report, it can be concluded that although cloud infrastructure has multiple
benefits on its implementation within Metasoft limited, the different risk factors have to be taken into
consideration before its implementation. Risks associated to data insecurity and privacy reach have to
be eliminated and mitigation techniques to be incorporated within the company, such as introducing
audit trails to keep a track of which employee accessed what information at what point of time from
which system. If Metasoft limited is successful in maintaining proper mitigation techniques at the time
of cloud migration, it will be able to come up with a much smoother process of business operation s and
improved data security as well as other advantages.
