Answer 1
Part a
Hybrid cloud architecture is the most implemented technology of modern time for
different IT related solutions in different data management systems (Wan, Zhang, Zhao, Yang, &
Lloret, 2014). The vendors used the term “hybrid” because the architecture is a perfect blend of
public and private cloud architecture and a great solution for different IT related problems in one
form. When single or multiple public cloud structures are connected to a private cloud structure
of a data center with a traditional infrastructure then the overall structure is termed as hybrid
cloud architecture (Shifrin, Atar & Cidon, 2013). This is only possible only if both the structures
have some kind of evenness between them. The greatest advantage of implementing hybrid cloud
architecture is it enables sharing of data and workload between the public and private cloud
based on demand, supply and cost of the service. In this way, the architecture provides greater
flexibility to the overall operation (Almorsy, Grundy & Müller, 2016). In other terms when if a
company with private cloud structure wants to incorporate with the public cloud structure of any
external trader then hybrid cloud architecture is the best chance for them.
MetaSoft Ltd, a software development company based in Australia and New Zealand is
looking for a perfect hybrid cloud architecture for their company. This is because they are
closing down their oldest data centre in Melbourne and trying to collaborate the workload of this
centre with the most updated one in Sydney centre. They are planning to increase the capacity of
the centre by implementing a suitable hybrid cloud architecture to increase availability and
flexibility in their services in data supply to their existing and new customers. Here in this report,

2PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
a thorough study on suitable hybrid cloud designs and their benefits and risk assessments are
studied and the best solution for the company is suggested.
Different Hybrid Cloud Architecture
Hybrid cloud architecture is a good solution data management companies can think about
as the solution for the company. Implementing a new structure from the beginning is quite easier
than transition to a new one. Here some popular hybrid cloud architectures are given below.
AWS Lambda: this is a highly popular hybrid cloud computing architecture as it provides some
huge benefits. Using this architecture, one can run a program without the help of any external
server. This architecture runs your program and expands it in case it is necessary for a few
permission per day to thousands every second. A vender has to pay only for the time he requires
for computing. Otherwise, he does not have to pay while his code is running. The best feature of
AW Lambda is, a vender can use program of literally anything or even of backend servicing in
this cloud without any administration (Breiter & Naik, 2013). The program of any vendor will
run in highly available computer infrastructure. This hybrid cloud architecture s highly beneficial
for data Management Company like MetaSoft. The AWS Lambda is the best one to handle
multiple venders and with limited hardware infrastructure. Starting from cost of implementation,
the benefits of this architecture are numerous. The data management company need to separate
the requests based on time division only to get the best results. In addition to this, changing over
from an existing architecture to AWS Lambda is quite an easy task. No need to worry about huge
hardware implementation or a thorough changeover. The AWS Lambda architecture can easily
be implemented with any existing hardware set up. The data company needs to implemented
time slot division based request and implementation system for AWS Lambda.

3PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
However, the risk factor associated with AWS Lambda is quite alarming. The
responsibility of the private server is solely of the data management company. The vender is no
way associated with this. The responsibilities of the company to design manage and maintain the
private server. This means they also have to take good care of the codes of the vendor. The
vendor cannot be blamed for any kind of error in the system. For those who are changing over
from an existing architecture to the AWS Lambda architecture they need to be aware of this risk
factor. MetaSoft need highly experienced expert IT professionals to design the system for them
to avoid any kind of error (Fazio, Celesti, Villari & Puliafito, 2014). In addition the company
also needs experienced people to handle the system and deal with the vendors and clients. This is
important for only such people are able to understand a complicated system like this.
Azura functions: Unlike the AWS Lambda, this system does not use time slot based code
implementation. This is a system where codes are recalled based on events or occurrences. Only
when a vendor program is recalled externally, the program will run in the system without the
intervention of main server. The vendor programs will be uploaded in the private server of the
hosting data management company and will be recalled only when a request comes to the public
server to run the code. The code can be of anything related to the vendor or the client. The host
company will not interfere with the choice of coding. The vendor company will also be charged
for the code simulation only. The vendor or the client company does not have to pay anything for
the external events for which the code will be recalled. This work can be done from few times a
day to thousand requests per second. The client does not have to pay anything. The best feature
of Azura Functions is this. The client pays only for the coding and do not have to be concerned
about the events (Flores & Srirama, 2013). The responsibility of the host data management
company is to take control of the events and recollection of the programs. Every time a program

4PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
is recalled by an event, it is the duty of the host company to get the code from the private server
and upload it in the public server without any intervention.
However, the duties of the host data Management Company is the highest risk factor
associated with this architecture (Grozev & Buyya, 2014). The responsibility of the host
company is to handle all the requests and recall the associated programs. This requires a he
expertise; otherwise the overall system can go wrong. In case of changing over from existing
cloud architecture this can be quite complicated as the host company needs to train their
employees to be accustomed with the new system. However, things can go pretty wrong in case
of wrong call. The vendor can lose a fortune and the host might have to pay back. This is the
high risk factor associated with this hybrid cloud architecture.
The challenges of Hybrid Cloud
Besides these super beneficial sides of hybrid cloud architecture, there are, some
challenges related to the technical, management administration and business aspects which
hybrid cloud architecture offers (Moreno-Vozmediano, Montero & Llorente, 2013). The reason
of these is mainly the workload of the private cloud, which need direct access to public cloud
structures. Hybrid cloud architecture requires compatibility between the private and public cloud
structures and a proper connectivity. However, the public cloud part suffers a lot due to
connectivity errors, service breaches and every possible disruption in the service. Data
Management Company has to implement complex hybrid cloud structure with workloads shared
with more than one public cloud providers. This has a huge risk of data security and complicated
design structure of the overall architecture. To mitigate this, companies generally break down the
overall workload to specific public cloud service providers.

5PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
Another risk factor is the company has to take the full responsibility for the support
system of the private cloud structure (Pluzhnik, Nikulchev & Payain, 2014). They are bound to
provide every kind of changes to support the public cloud and service changeovers with time.
The data management company has to take full care of the construction and overall maintenance
of the private cloud part of the architecture (Zhang, Jiang, Yoshihira & Chen, 2014). To do this
they need to have experienced local IT experts and cloud architects for help. The company is
solely responsible for this.
Part b
Benefits of implementing Hybrid cloud architecture
There are two most important benefits of a hybrid cloud architecture can be identified
from the overall structure. They are as follows.
 The hybrid cloud structure is highly flexible and expandable. However, implementing
hybrid cloud structure requires extra financial support with time but it provides flexibility
to the system. in case the requirement of a vendor excides the capacity of the public cloud
then the private cloud will immediately be implemented in rescue in such conditions. In
addition to this, in case of oversees vendors demand can vary due to geographic
differences and other parameters. Hybrid cloud structure is scalable enough to handle
such conditions too.
 Initially implementation cost can shoot high but the hybrid cloud architecture can be cost
effective in terms of data management. The public cloud component of the structure
provides cost-efficient solution for IT related problems without any recurring expenses

6PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
and extra costs. Even IT expert designers can design the best quality configuration and
the locations without any excess cost. Even the services can be changed and redesigned
as per the requirement without any extra cost.
Answer 2
Risk factors associated with the above hybrid cloud architectures and the solutions
The risk analysis is a major process, which is essential for a changeover to be analyzed
before implementing a new system (Nikulchev et al., 2015). Shutting down a total data centre
and shifting the workload to a new one requires a thorough planning for any data management
company. Risk analysis is the most important one of them.
There are many risk factors in the overall process of changeover. The most important challenge
of implementing hybrid cloud architecture is the added responsibility of the host company of
handling the private server part of the hybrid cloud (Paul, Govindarajan, & Chatterjee, 2013).
This is important as all important information and codes regarding the client companies and the
host companies will be saved their (Serrano, Gallardo & Hernantes, 2015). The host company
has to give importance to the maintenance of the system( Leavitt, 2013). This is true for both the
hybrid architectures. In the case, it s the responsibility of the company to design and maintain the
private server of the system.
In the second case, the host data company has to implement extra care to the system as all
the information regarding the server and the client company will be saved in the private server
(Wan et al.,2013). Any kind of data leakage from the server can be harmful to both the host and
the client company. The host company has to take very delicate care of this fact.

7PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
In both cases the best solution to these is recruiting expert IT professionals and hybrid
cloud architects who are able to design and maintain a secure system. In the first case the
company does not have to worry for any hardware changeover because the design does not
require any. With the existing architecture a new AWS Lambda hybrid cloud design can be
implemented (Dobre, Viotti & Vukolić, 2014). Only thing the company has to do is change the
existing process into a time-slot division based system (Yadav, 2013). In the second case the
company does require some hardware changes which can be determined by any expert cloud
architect. This design requires some changes to the existing system because all the information
will be saved in the private server (Goyal, 2014). In case of Metasoft, recruiting local IT experts
should be enough for overcoming this situation.
The above discussion of risk factors associated with different hybrid cloud architectures and their
relevant solutions are given in a short chart format as follows.

Answer 3
General information security system for the company
Information security system is of highest priority to any host company. It is
recommended that while changing over the company must pay attention to this aspect Huang &
Du, 2014). Data security is the utmost important parameter for any data management company.
While implementing hybrid architecture, the company should take care of the security aspect as
all the information of the client company will be saved in the private server section of the overall
system. On top of that, the public server time to time for running different programs of the client
companies (Katyal & Mishra, 2014) can use the private server. It will be easier for anyone to get
access to the private servers in this way. The host company should implement highest-level
security software to handle such conditions. Enabling firewall for getting access to the servers is
also required, as this will help in building layered security systems.
Answer 4
Recommendation for MetaSoft
The company will have to implement new strategy to cope up with the changeover. To
reinstall all the programs and information in the new system of the Sydney facility. Shutting
down an old facility, which is supporting numbers of vendors and clients, is not a good choice in
the first hand. This will create a huge crisis in the company. The first and the most important one

10PERFECT CLOUD ASCHITECTURE FOR METASOFT LTD
is the technical crisis of the changeover. This requires increasing the capacity of the Sydney
facility and systematically installing the entire client codes in the private servers available there.
The private servers have to be reconnected with the public servers to rebuild a new hybrid cloud
architecture. As a whole, this will create huge chaos among the clients as well as the employees.
The second crisis is the ethical part. An environment of instability will grasp the
confidence of the employees as shutting down a facility will means there will be a down serge in
the list of employees of the facility. People will lose confidence and this will affect the
performance. On the other hand, a chaos among the clients will need constant consultancy and
improved marketing strategy to cope with it.
The best solution to this problem is to remodel the Melbourne facility to avoid such
chaos. However, if the company is not willing to invest in remodeling the facility and move
forward with the new and advanced facility of the Sydney Centre then AWS Lambda is the best
solution for company for the changeover. This architecture will reduce the pressure of
changeover as it offers auto recall of client programs from private servers. All the company
needs to recruit some local expert Hybrid Cloud architect to design the system and train the
employees about the maintenance of the systems.
Whenever a data management company, like Metasoft, is looking for a changeover in
their system hybrid cloud architecture can be the best solution for them. Different hybrid
architectures allow the host companies to manage higher number of clients than earlier besides
making the overall system quite easy and manageable for Host Company. In addition to this, the
hybrid architecture allows the host company to manage more data than earlier with a limited
hardware changing. There are different architectures available with different benefits with them.

However, every architecture has its own short-comes to be addressed. It is the decision of the
company that which one they will choose for their best results.
