Introduction
This report outlines about cloud systems and applications as from past several years, there is
a significant growth in cloud computing together with new concepts, technologies and
paradigms of its stack i.e. IaaS, PaaS and SaaS. It also includes adopting of these three
paradigms in various business sectors globally under cloud management principles and
specifications. In today’s digital and competitive world, cloud computing has develop to be a
reliable way to carry on enterprise applications and the ideal solution for organisations
encompassing their infrastructure or introducing innovative concepts. Companies of every
type, size and industry are using cloud computing for wide varieties of purposes. This
technology benefitting the companies in various ways like reducing the time to market of
applications required to gauge with dynamism, giving access to a broad range of technologies
enabling companies to innovate faster and so transform customer experience together with
saving of costs and achieving economies of scale (Assunçao et al, 2015).
Cloud computing, its characteristics and development
trends
Botta et al (2016) defined cloud computing in a general mean for anything that includes
providing hosted services through the internet. Effective implementation of cloud computing
requires a cloud infrastructure relating to the software and hardware constituents and it can
also be thought of as utility computing or on-demand computing. In relation with existing IT
systems, cloud adoption to accelerate IT modernization driven by a complete standardization
and automation strategy. However, the inclusive value of cloud computing originates from
impending these choices not as one-off tactical selections though as a part of a holistic
approach with pursuing digital transformation. In addition, embracing cloud is a substantial
enabler of the significant automation and standardisation as it leads to reduction of IT

overhead outlays by 30 to 40 per cent, help in scaling IT procedures, improving the whole
flexibility of IT in fulfilling corporate necessities and ultimately reducing IT incidents by 70
per cent (mckinsey.com, 2018).
Cloud computing claims various advantages for the organisations and ends handlers and its
certain characteristics contains self-service provisioning, elasticity, pay per use, workload
elasticity, migration flexibility, broad network access and multi-tenancy and resource pooling
(Omer, Mustafa and Alghali, 2014). In relation with self-service provisioning, the users can
undertake almost any workload on demand including provision of computing capabilities like
network storage, server time and eradicating the conventional requirement for IT
administrators. This technology also presents elasticity with eliminating the organisational
needs for huge investments in local infrastructure and allow business to scale up computing
needs upsurge and scale below when reduce in demands. Workload resilience in cloud
computing ensures resilient storage and retain users significant workloads running –
frequently across various world-wide territories. Organisation can also change their cloud
platform from one to another for the purpose of better efficiency or cost savings and hence
this offers them migration flexibility (Kantarci and Mouftah, 2015). In terms of multi-
tenancy, users can hold their security and privacy over their own data with relying upon
similar physical infrastructure and considering resource pooling, customers can be given
necessary cloud services using same physical resources, however, it requires to be flexible
and large enough for fulfilling the needs of multiple groups of consumers.
The trends and development in cloud computing move at a pace that can be infuriating to
follow and impossible to project and many of those developing cloud computing trends stem
from the industry entering a phase of standardisation and increased capability – a symbol of
maturity in any technology industry. In relation to trends, adoption of cloud computing will
continue to grow rapidly as today almost a quarter of companies using cloud based
