How to Write an Executive Summary -

Executive summary:
Microservices indicates the different types of software development techniques.
It has been the variant of the architecture that is service oriented having
structural style. It has been arranging applications to become the collection of
numerous services coupled in loose manner. Furthermore, here the services can
be fine-grained. Again, various protocols are been seen to be simple type. In this
report, different credentials of the professional implementing microservices at
DXN technology are demonstrated. Next, a historical narrative is also evaluated.
Lastly, different kinds of software architectures are also defined.
Establishments of credentials for DXN Limited:
For the present study the DXN Limited that has changed from Data
Exchange Network Limited is chosen as the organization. It has been redefining
the way current-day data centers are been operated and constructed. This
emerging business is been developed on shoulders of experienced group.
Collectively this has long years of experiences at the areas of construction,
telecommunications and data centers with environmental, electrical and
mechanical engineering. Here, I as a consultant client is appointed to understand
the introduction of the micro-services usages. A survey is needed to be done on
the long history of computing and demonstrate why and how the current

contemporary information suite systems are basically different from the
technology generations and is used across the ages. Thus, from that point, a
framework and definition for the software architecture is to be demonstrated. It
also involves the why that is vital for the DXN Limited.
Thus my role is as the consultant client is confirmed. I have a degree in
software engineering and architects. I have been developing, designing and
deploying different service-oriented service based systems at many
organizations. I have also worked as project manager for 3 years and technical
manager for two years to migrate the legacy systems and involved in managing
micro-service implementation. I have been expert in making implementation
guidance to develop different informed design decisions. This also involves the 7
principles for the designs of SOA and much more than fifty design diagrams
conveying SOA strategies. I have worked in hands-on design laboratory where
the attendees are able to investigate the architectural designs that are service
based.
Introduction:
The microservices denotes to various techniques of software development.
This is the variant of service–oriented architecture in structural style. This
arranges the application to be the collection of various services that are loosely
coupled. Under this architecture, the services are been fine-grained whereas the
different protocols are seen to be lightweight in nature. The following study
makes the establishments of various credential from the provided case. The
historical narrative is also demonstrated here along with the definition of
different software architectures.
Historical narrative:
The history of computing can be traced back for the necessity to resolve
serious crisis of number-crunching and never for email or entertainment. Till
1880, the population of U.S. is seen to be growing so much huge that seven
years were taken for tabulating the results of U.S. Census. For that the
government searched for quicker ways to get their tasks done and thus
developed punch-card based systems. These took up the entire room. It has
been documented by Martin Fowler that the as a term micro services has been
used at the workshops of“software architects”during 2011. This happens as the
participants are seen that they exploring individually same type of ideas parallel
with software architectures. Moreover, the community gave the confirmation
that the names has been demonstrating that latest paradigm as they met on the
upcoming days. It was James Lewis giving presentation at the 33rd Degree during
2012 at Krakow (Herrera-Quintero et al., 2018). This happened in a talk named
“Microservices, Java, the Unix Way”outlining the innovation as they can develop
the software very fast through conquering and diving through using the
Conway’s Law for structuring groups (Balalaie, Heydarnoori & Jamshidi, 2016).
For its every virtues, the microservices has not been specifically innovative or
fresh. Here, the roots can be traced 30 years before the world of Unix. Moreover,
he has determined of important properties making the microservices to be
unique (Xu et al., 2019). Here, the most important thing that is unique is the vital
to keep the services to be independent such that they could be replaced
individually despite affecting the overall application. Those requirements are

established as the various organisation services across the business are active
through the dumb pipes and smart endpoints. From that specific time, the micro-
services uses are seen to be accelerating. These architectures have been fast as
per Fowler. Thus they have turned the default type of style for create the
enterprise applications (Aderaldo et al., 2017). Though the traditional wisdom
has been holding the microservices to be suited best for deploying the software
projects that distributed in nature and brand new. As per a current survey done
by Red Hat, it is seen that most of business has been utilizing the micro services
to be deployed successfully to re-architect the legacy applications (Jaramillo,
Nguyen & Smart, 2016). Thus, more than 69 percent or two-third of the
respondents revealed that they have using the technology for modernizing the
current ones and new applications. Thus the benefits has been accruing very fast
as per the survey that about one thirds of the business gain benefits under 2 to 6
months after the microservices are first deployed (Ghofrani & Lübke, 2018).
Definition of software architectures:
The software architecture of any system or collection of various systems
comprises of various vital decisions regarding design regarding software
architectures. Here, the interactions between the structures consist of that
system and the design decisions are able to support the intent quality sets. This
must be system to stay successful. This decisions of design delivers the
conceptual basis for the maintenance, support and system development. For
DXN Limited it is helpful as this software architecture of the computing system or
program is depiction of the system aiding to analyze how the systems are able to
behave (O'Connor, Elger & Clarke, 2017). Moreover this serves as the effective
blueprint for the system and the project that is developing that. The defining of
the assignments of work should be done through implementation and design
teams. This architecture is the main system career having qualities like security,
modifiability and performance. Here, none could be gained despite any unifying
kind of vision of architecture. This is the artifact of the prior assessment for
assuring that approach of design can yield the acceptable system. Through
creating the efficient architecture, one can determine the risks of design and can
mitigate tem earlier for the process of development (Salah et al., 2016).
Firstly, there is the layered pattern. It can be utilized for structuring the
various programs decomposed to various subtasks. All of them are at a specific
abstraction level. All the layers deliver the services to further layers. This has the
common desktop applications and e-commerce web applications (Chalmers &
Pedersen, 2018). Further, it has the pattern of client server. It comprises of two
parties that have multiple clients and one server. This provides effective services
to numerous clients. This has different online applications like banking,
document sharing and emails. Next, there is the master slave pattern conspiring
of two parties named slaves and masters. For the replication of database, master
database is seen as authoritative source and slave databases are been
synchronized here. Moreover, the peripherals are linked to bus in computer
system (Selimi et al., 2017). Next, there is the pie-filter pattern could be used for
structuring system processing and producing data streams. Again, the compilers
are there. Here, the consecutive patterns can perform the parsing, lexical
analysis, code generation and semantic analysis. Then, there is the broker
pattern utilized for structured and distributed system having components that
