2. these
days is seems like everything is happening “in
the cloud”. But what exactly is this nebulous
concept?
The short answer is that it's somewhere at the
other end of your internet connection – a place
where you can access apps and services, and
where your data can be stored securely.
The Cloud Is
A Big Deal
For Three
Reasons:
It doesn't need
any effort on
your part to
maintain or
manage it.
It's effectively
infinite in size, so
you don't need to
worry about it
running out of
capacity.
You can access
cloud-based
applications and
services from
anywhere – all you
need is a device
with an Internet
connection.
What is
Cloud Computing?
3. •The flexible provision of CPU
capacity, data storage, network
bandwidth and basic operating
system. Each customer is
responsible for running their
software stack on top, and is
able to re-size the underlying
Cloud Infrastructure (CI) on
demand.
Infrastructure
as a Service
(IaaS):
•This adds to CI a complete
software stack; for example
LAMP (Linux, Apache, MySQL,
PHP/Perl). Each customer is then
able to write or load applications
into this known environment,
with the provider responsible for
expanding or contracting the CI
and/or the software landscape
to meet changing demands.
Platform as a
Service (PaaS):
•This takes CI and Cloud Platform
(CP), then adds a complete
preconfigured application
environment, for example
salesforce.com or Google Apps.
The customer simply consumes
the application as a service,
usually on a per-user basis, and
has no long-term commitment
(but equally almost no control).
Software as a
Service (SaaS):
Service Models
4. Deployment
Models
Public Cloud:
A public cloud service is built on
an external platform run by a
cloud-service provider. With this
off-site cloud service, users get
their own cloud within a shared
infrastructure. The provider
offers everything from system
resources to the security and
maintenance of your cloud
system. Since it is managed by an
outside company specializing in
cloud services for a large range
of customers, a public cloud
system is great for organizations
that want more elasticity, cost-
effectiveness and the latest
technology.
Private Cloud:
A private cloud service is a cloud
platform built within your own
walls on your own hardware and
software. Since a private cloud is
managed by your own internal IT
team, it is ideal for businesses
that want exclusive access, more
flexibility and greater control
over their cloud. To use a private
cloud service, however,
organizations build their own
data centers, making it a costlier
cloud option.
Hybrid Cloud:
A hybrid cloud service employs
both private and public clouds. In
a hybrid cloud system, an
organization’s own IT team
manages part of the cloud in-
house and the rest off-site. For
instance, a hybrid cloud system is
perfect for an organization that
wants to manage business-
related data (such as customer
files) in-house but wants to store
less-sensitive information with a
third party. Hybrid cloud systems
are used by all types of
organizations but are 46 percent
more likely to be used by larger
organizations with more than
1,000 employees, according to
the Neovise research.
5. Aim
Our Aim is to
implement
with
all types of
Service Models.
6. Business
Overview
Our main business purpose is to provide
cloud computing services to any personel,
small,medium or large enterprenures
including local or international agencies
in Australia.
7. Background
Here are some other reasons why every enterprise
might need cloud computing for their business:
Cost Savings - Cloud computing removes the requirement of a company
to invest in storage hardware and servers.
Focusing On The Business -Since all the services will execute over the
internet, a company does not have to bother about technical issues and
other problems associated with physical storage and backup. A
company can thus focus more on their core business.
Performance - It delivers reliable performance irrespective to the
geographical location of the user. Another key feature could be the
automatic updating of services and applications.
Security - Cloud Computing offers optimum security which protects you
against any unauthorized access, modification and loss of data.
Flexibility - Even if part of the cloud environment fails or stops working,
the other resources continue to work until the problem is fixed.
8. Scope
It is predicted that by 2016 over a quarter of all applications (around 48 million) will
be available on the cloud (global technology outlook: cloud 2014: A more disruptive
phase).
Based on their forecast for 2011-2017, it is expected adoption to hit $250 billion
by 2017.
50 percent of enterprises will have hybrid clouds by 2017
85 percent of the new software being built today is for cloud
9. Limitations
Privacy
agreement and
service level
agreement
You will need to have suitable agreements in place with your service providers before services
commence. This will safeguard you against certain risks and also outline the responsibilities of each
party in the form of a service level agreement (SLA). You should read the SLA and ensure that you
understand what you are agreeing to before you sign. Make sure that you understand the
responsibilities of the service provider, as well as your own obligations.
Security and
data protection
You must consider how your data will be stored and secured when outsourcing to a third party.
This should be outlined in the agreement with your service provider, and must address mitigations
to governance and security risks. It must cover who has access to the data and the security
measures in place to protect your data.
Location of data
Cloud computing service providers are often located outside Australia. Before committing, you
should investigate where your data is being stored and which privacy and security laws will apply
to the data.
Legislation and
regulation
You will need to be aware of Australian legislative and regulatory requirements when storing
personal data (e.g. the Privacy Act 1988 and the Archives Act 1983 (Cwlth) will apply). If the data is
being stored outside of Australia (e.g. if your business uses an overseas service provider), you will
also need to be aware of the legislation and regulation requirements in that geographic location.
