- 1. Cloud Computing Business Scenario
- 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 organizations 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.
