Critical Examination of Challenges: Mobile Distributed Systems

This essay delves into the multifaceted challenges encountered in the realm of mobile and distributed computing systems. It highlights the increasing need for scalability in modern distributed systems, particularly in terms of maintenance, operators, and resources. The essay identifies two primary challenges: the integration of human operators within socio-technical systems and the long-term management of expanding systems. Key issues such as heterogeneity, openness, concurrency, transparency, security, failure handling, and scalability are critically examined from the perspective of system analysts and designers. The discussion underscores the importance of adaptability, strong ethical principles, and effective communication skills for system analysts to navigate these challenges and foster successful client relationships.

Introduction
Various modern distributed systems are required to scale in respect of the maintenance for the
process, operators, and the sources. In addition, the systems are necessary to operate across
the internet and through various structural areas. These scalability needs lead to various
recognised issues, where the distribution transparency requires to be operated contrary to loss
of presentation. There are two major challenges for which people claim there is no easy
solution. These issues arise from the particulars that operators and systems are becoming
increasingly combined and they are leading to the socio-technical distributed system at large
scale. The people recognise the project of the integrated system as an issue, particularly when
it is required to place human beings in the circle as the requirement to appropriate function of
the systems completely. As operators are so firmly unified in the whole project, and system
reasonably expand by arrangements, the individuals would be taking issues regarding the
long-term management that people recognise as other main issue.
In the following parts, the challenges related to spread of mobile and distributed computer are
discussed and critically examined.
New challenges for system analysts-
Creation of the distributed system does not come as simple. Various issues need to be
astounded in respect of getting the best systems (Rhazali, Hadi and Mouloudi, 2016). The
following are the major challenges related to distributed systems for the system analysts or
the designers-
1. Heterogeneity

ESSAY 2
The Internet makes able the operators to access the service and operate application above the
mixed assortment of the computer, network and mobile (Sabegh, and Recker, 2017).
Heterogeneity makes able to all of the following-
 OS, Microsoft Windows, Linux, Unix and Mac
 Computer, laptop, mobiles, implanted tools
 Local network, Internet, WLN , satellite link
 various role of software developers and system analyst and designer
Various languages of programming use different representations for characters and data
framework like ranges and proceedings (Murphy, et. al, 2016). These differences should be
stated if the programs written in various language are to be capable to make communication
with others. The Programs made by various creators may not interact with others except they
use general norms (Zheng, et. al, 2017).
2. Openness
The openness of the computer system or mobile is the characteristic that decides whether
systems may be comprehensive and implemented in the different manners. The openness of
distributed systems is decided basically by the level to which new service related to source-
sharing may be added and be made available for use by the multiplicity of the client
programs. If the well-defined edges for the systems are circulated, it is simple for developers
to add new features or substitute sub-system in coming period (Fotache, Olaru and Iacoban,
2015).
3. Concurrency
The service and application render sources that can be shared by the customers in the
distributed system. There is therefore the chances that various clients would go to access the
shared source at similar period. For an instance, the data framework that records bids for the

ESSAY 3
auction can be accessed very repeatedly when it comes close to deadline period. For the
objective to be secure in a simultaneous atmosphere, the functions should be harmonised in
the manner that its data remains reliable. It may be attained by standard technologies like
semaphores that are utilised in most operating systems.
4. Transparency
The transparency refers to the suppression from the operator and application programmer of
departure of elements in distributed systems, so that system is invented as whole rather than
as assortment of independent elements. In other words, distributed system designers should
hide difficulty of the system like as much as they can (Dey, et. al, 2016).
5. Security
Many of the information sources that are made available and maintained in distributed system
have a high intrinsic value to the operators. Its protection is consequently of substantial
significance. Protection for data resources has three elements-
 confidentiality like security against disclosures to illegal people
 Integrity like security against the modification or dishonesty
 accessibility
6. Failure handling
Sometimes, the computer systems and mobiles sometimes can fail. In the case, where faults
take place in the hardware or the software, programs can generate improper outcomes or may
stop before they have done the planned calculation. The treating of disappointments is
specifically difficult (Capretz, Varona and Raza, 2015).
7. Scalability

ESSAY 4
The distributed system should be accessible as the number of operator enhances. The
scalability system is known as ascendable if it may tackle the addition of operators and
sources without distressing the visible harm of performance or increase in managerial
difficulties. It has following three dimensions-
 Geography- it is space between the operators and sources. The main difficulty is
communication.
 Size- it is quantity of sources and operators to be practiced. The main problem is
about the overcapacity.
 Management- when the size of the distributed system is boosted, then the various
systems are required to be managed. The main problem is connected with managerial
mess (Al-Samawi, 2016).
Conclusion
As per the above discussion, it is cleared that the system analyst or designer should be the
self-motivated and enthusiastic person who is capable to handle and direct other individuals,
as well as uncountable sources related to project. The system analysts and designers face
various challenges presented by the spread of mobile and distributed computer systems. It is
required by the system analysts and designers to handle the conditions at hand in the
systematic way by the implementation of the devices, technologies, and knowledge. The
system analysts and designers should be able to communicate in the meaningful manner. The
system analysts and designers should be capable to know the requirements of the human
being in making interaction with techniques. It is recommended to system analysts and
designers to have strong individual ethics and professional morals to assist them in creating
the client relationship.
