1. 1. Cloud Computing Business Scenario
2. 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. 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. 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. 5. Aim Our Aim is to implement with all types of Service Models.
6. 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. 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. 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. 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.
