This academic report will cover what the Information Technology Infrastructure
Library is and how it is used in industry. I will also be going over
what cloud computing is how its used, advantages & disadvantages and
current obstacles faced by both organisations using cloud computing services
and cloud service providers.

 

An Example of a cloud computing service provider that ill be
referring and often insinuating to is Amazon Web Services (AWS). Amazon
Web Services is a subsidiary of Amazon.com

which provides it users
with on-demand cloud
computing platforms. Users of the service may be individuals, companies
and even governments. The organisation offers a paid subscription basis with a
free-tier option available for 12 months. The technology allows subscribers to
have at their disposal a full-fledged virtual cluster of computers, available all the time, anywhere as long as the ends
user has access to the Internet.

 

In 2017, AWS comprised more than 90 services spanning a wide
range including computing, storage, networking, database, analytics,
application services, deployment, management, mobile, developer tools, and
tools for the Internet of Things.

ITIL (Information Technology Infrastructure Library) is a
set of best practices that depict and define the internationally accepted
engagements practised in an IT management infrastructure regardless the size of
the organisation or the technology they use.

ITIL endorses a quality approach to achieving business
efficiency and effectiveness within the use of information systems and because
of this it is one of the mostly widely accepted methodologies in the world.

 

Part of the reason why ITEL works so well is because it describes the “what” a service provider must
do, not the “how”, via this approach ITIL recognizes that industry, maturity
level, size, and other factors differ for every organization.

Cloud computing is the
practice of using a network of remote servers hosted on the Internet to store,
manage, and process data, rather than a local server or a personal computer.
(1)

The following 5 principles
support a higher level of definition of a cloud service and how they’re
typically designed: Rapid elasticity, Resource pooling, Network access,
on-demand self service and measured services. (2)

 

The first of the five
characteristics that build up a cloud computing service is ‘Rapid elasticity’
which allows users of the service to seamlessly request more storage space
within a cloud or any another type of service available, this is a key feature
in creating a virtual environment appearing to be infinite to users due to its
impressive, consistent reliability for storage space. This type of service is
unique to cloud computing and computing services.

 

Another vital characteristic
that builds up a cloud computing service is resource pooling, this is done by
companies allowing clients of the facility to change their level of service as
well and without being subject to any of the virtual or physical resource
limitations. Cloud computing services that can apply the resource pooling
strategy include data storage, processing services, and bandwidth provided
services. All these services can be customised to suit each users needs without
any changes to appearance (relating back to Rapid elasticity).

 

Amazon Web Services leads the cloud space by having a large variety
of tools and importantly the right combination of tools all in a single
platform

 

Microsoft Azure is close behind and in second places just
lacking in the impactful execution that Amazon Web Services has adopted.

 

Google Cloud is the next most promising cloud player and is
gaining ground on its two leading competitors rapidly. (5)

 

A successful cloud computing
service strategy constantly insures that it always has broad network access
which refers to resource hosting within the private cloud network and the
company’s firewall. These resources and services are then assessable from a
wide verity of devices such as smartphone phones, PC’s, Laptops and Tablets.

 

A part of managing of the cloud services includes monitoring services for various reasons, including
billing, effective use of resources, or overall predictive planning this
elaborates the idea that in automated remote servicing the measuring load
provided will be assessed and used by both the user and client of the cloud
service provided.

 

The use of ITIL and cloud computing work cohesively as cloud
computing doesn’t require a bulky investment cost to start up and further
investment doesn’t have to commence until actually demand occurs plus cloud computing
is built to offer usage on-demand. the implementation of ITIL conveys
advantages such as; by adopting established standards that are proven to work,
service providers are beyond liable to deliver services consistently to the
agreed service levels, both effectively and efficiently throughout a company
such as ”Amazon Web Services”.

 

The adaptation and use of an ITIL’s
service strategy incorporate benefits such as the reduction of unforeseen and
unintended resource pooling and unforeseen cost’s, this is done by simply
executing better handling of service outages and the superior methods of identification
of root courses in unexpected circumstances. And therefore by ‘Amazon web
services’ embracing ITIL’s service strategy practises it’ll enable the business
and its customers to add value to the service they’re receiving/offering by
reducing downtime and fundamentally a competitive advantage in the
market place.

Acquiring an on-demand self services is an essential element
to achieve effective and suitable operation of the cloud services provided,
this specific feature allows cloud computing users to run their own sessions
without interaction with the service provides.

 

With good practise of ITIL’s
service operation strategies cost’s can be associative due to the flexible
resource allocation model of the cloud, this then allows for innovative
thinking with respect to ways of partitioning all the larger scale problems ”Amazon
Web Services” may be facing.

 

Event management plays a fundamental role in ensuring
functionality and operational health of the IT service is to its optimum
standards

 

The ITIL specification defines an event as “any detectable
or discernable occurrence that has significance for the management of the IT
infrastructure or the delivery of IT service.” In other words, an event is something that happens to an
IT system that has business impact.

An occurrence can
be anything that has material impact on the business such as environmental
conditions, security intrusions, warnings, errors, triggers, or even normal
functioning. Occurrences are things ‘Amazon Web Services’ needs to monitor, adaptation
of ITIL’s practices and teachings will certainly, give them the visibility they
need to run your systems more efficiently and effectively over time with
minimal downtime.

 

Continual Service
Improvement (CSI) continually improves the effectiveness and efficiency
of services and processes. As per ITIL 2011, benefits to the organisation financially include
cost-effective provision of the services provided by the institution as well as
list of cost justifications for the infrastructure and all services provided.

 

A company such as ‘Amazon Web
Services’ is found to be well-suited with ITIL’s 5th phase of the
service lifestyle, as subsequently like CSI demonstrates the organisation
was initially structured to organize and describe all of it’s activities and
processes involved in planning, creating, managing, and supporting modern IT services.
(4) It also offers practical guidance and comprehensive guidelines for
establishing, developing, and running cloud- based IT capabilities.

  

By following and implementing
ITIL’s continuous Service improvement parameters organisations such as ‘Amazon
Web Services’ and others alike will find themselves reducing there cost and respectably
increasing profits by implementing the relative adjustments and changes to the
way they operate, and continuously improving the way they’re currently operate
if fulfilling of ITIL’s CSI strategy guidelines.

 

CSI can encouragement the improvement
of ‘Amazon Web Services’ service reliability, stability and availability to
consumers; this them has a knock-on-effect on the company’s reputation for
providing excellent services and can attract new users and maintain existing
loyal users of the service. additionally, the use of continual service improvement improves the
metrics and measurements the organisation uses to monitor its goals and
objectives, makes sure all decisions and actions to take are well-defined and
approved against industry standards.

ITIL’s Service Strategy
provides guidance for a service organization to operate when entering the
market and the opportunity to grow successfully in the long term by providing
operational results and data for decision support in a strategic manner, while
transforming Service Management capabilities into a strategic asset.

 

ITIL’s primary focus is to
develop the capacity to achieve and maintain a strategic advantage and aims to
refine policy’s, guidelines and process across all the service life cycle.

 

The increasingly common
use of containers is increasing and companies are going the ability to migrate
their entire systems to a brand new cloud computing vendor all for a small
discount. This then means for company such as Amazon with spare capacity
can entice other organisations for fairly low prices considering it just needs
to cover its operational costs.

 

Companies like
Amazon Web Services know this already and are using it to their advantage to
move up-market and provide additional services that are potentially within a
higher margin. Nevertheless, even if for-instance Amazon can’t end up pulling
it off, it will most likely remain the dominant cloud computing platform in the
market for a long time because it is the only large technology organisation
that is used to competing within very low margin spaces. Companies such as Google
many have a tough time redesigning their culture to compete with the ultra
cost-conscious Amazon. 

 

 

An impediment often faced by cloud service providers is
security, an aspect such as security is fundamentally critical when working on
or storing data remotely on the internet.

Public Space online which is commonly cloud space is rather disreputable
for being the playground for script kiddie’s and Hackers. Cloud computing service provider’s such as google and
‘amazon web services’ consider (TLS) Transparent Layer Security which can
consist of traditional forms of encryption.

 

All software a used by consumers
to provide access to services must be thoroughly audited and maintained against
vulnerabilities. The use and Practice of ITIL’s ‘continues service improvement’
can aid an organisation to eliminate risk factors that could jeopardise a company’s
brand image or even the continuity of it.

Another Obstacle faced by
cloud computing service providers is the legislations they encounter, this can
be such as difficult area that many corporations struggle to overcome, often
because organisations must consider not only their own legislations with
regards to the storage of data and the export of information, but also the laws
regarding the same for the country of their provider.

This can occasionally have
very big implications for example: while data privacy laws in Germany are
almost inviolable, the laws overriding data privacy in the United States of
America are currently much less rigorous.

 

Often referred to as one of
the most problematic of all obstacles faced by cloud services is cloud data
migration.

cloud data migration is the
moving of existing on-premises data to a new cloud storage location in batches,
increments and via streams. In order for such transition to take place smoothly
and efficiently, cloud service providers must insure the following are taken
into consideration and professionally handled:

By shifting service onto the
cloud, user become increasingly dependent on a chain of third parties in order
to access business critical data, unlike many years ago when users just had to
be sure and check that their LAN connection was functioning and operational and
if so they can access what they needed in order to get on with the work that
had to be done.

 

However, with todays modern
Cloud Technology and the rang of service providers that are available to the
public, service providers must be sure that there is guaranteed uptime for the
service’s that run and rely on the cloud and the organisation’s internet
service provider (ISP).

 

In instances where an ISP
failure may occur an organisation can simply be resolve the situation by using
an alternate ISP during outages, and one of the benefit of using cloud service
comes into play by allowing access to business facilities via your mobile
phone, your tablet or laptop computer, as long as a cloud connect is useful and
an ISP is providing internet access.

 

However, this only a
temporary and short term solution to the problem as realistically its not very
practical to have everybody take their laptop down to Starbucks to carry on
with your day-to-day business activity.

 

After reading all these cloud computing challenges it may
seem a bit daunting, however its important to weight out the pro and cons and
as we know migrating to the cloud enables a business to:
