1. THE WHY OF A CLOUD ???? By, Sana Nasar
2. What is cloud computing? DEFINITION: Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. Cloud computing began as large-scale Internet service providers such as Google, Amazon, and others built out their infrastructure  A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc.  Cloud computing doesn’t require a software or a server to use them. All a consumer would need is just an internet connection and you can start sending emails. 
3. * How Do We Save Money By Using Cloud Computing Services? *There are many ways a company saves money by using cloud services, but it basically breaks down into a few simple categories: 1. Capital Expenditures (CapEx) - Every few years you purchase new servers, storage, and other computer related equipment. The cost of procurement is significant. Cloud computing eliminates much of this. 2. Physical Space - You have to put your equipment somewhere. That somewhere costs per square foot. 3. Server back-ups and server maintenance.- All that equipment needed for the maintenance are not required and updates in cloud happens automatically. 4. Electricity - All that equipment needs to be powered. 5. People - People with specialized skills are needed for managing and keeping managing in premise solutions.
4.  There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories:  Security issues faced by cloud providers (organizations providing Software-, Platform-, or Infrastructure-as-a-Service via the cloud).  Security issues faced by their customers.  The provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information But is cloud computing secure?
5. Do we Get Better Service At Lower Cost When we Move To Cloud Services?  Clouds are also comparatively easy to manage and bring down the costs.  Security in cloud computing is much better than a scattered network.  Cloud computing ensures that everyone uses the same computing standards with less down-time.  Accessibility from anywhere via multiple devices.  Brings down overall hardware and software costs.
6. How cloud computing works?????? In a cloud computing system, there's a significant workload shift. Local computers no longer have to do all the heavy lifting when it comes to running applications. The only thing the user's computer needs to be able to run is the cloud computing system's interface software, which can be as simple as a Web browser, and the cloud's network takes care of the rest.
7. Top Threats For Cloud Computing  Threat no 1: Security threats  Threat no 2: Outages  Threat no 3: Malicious Insiders  Threat no 4: Lack of information

9. TYPES OF CLOUD COMPUTING
10. Comparing Public, Private, and Hybrid Cloud Computing Options Cloud computing comes in three forms:  Public clouds.  Private clouds.  Hybrids clouds. Depending on the type of data clouds there are different levels of security and management required.
11. Public Clouds A public cloud is one in which the services and infrastructure are provided off-site over the Internet. These clouds offer the greatest level of efficiency in shared resources; however, they are also more vulnerable than private clouds. A public cloud is the obvious choice when  There standardized workload for applications is used by lots of people, such as e-mail.  Incremental capacity is needed (the ability to add computer capacity for peak times).  When doing collaboration projects.  When doing an ad-hoc software development project. Many IT department executives are concerned about public cloud security and reliability. Take extra time to ensure that you have security and governance issues well planned, or the short-term cost savings could turn into a long-term nightmare.
12. Private Clouds A private cloud is one in which the services and infrastructure are maintained on a private network. These clouds offer the greatest level of security and control, but they require the company to still purchase and maintain all the software and infrastructure, which reduces the cost savings. A private cloud is the obvious choice when • The business is the data and your applications. Therefore, control and security are paramount. • The business is part of an industry that must conform to strict security and data privacy issues.
13. HYBRID CLOUDS A hybrid cloud includes a variety of public and private options with multiple providers. By spreading things out over a hybrid cloud, you keep each aspect at your business in the most efficient environment possible.  Company wants to use a SaaS application but is concerned about security. The SaaS vendor can create a private cloud just for your company inside their firewall. They provide you with a virtual private network (VPN) for additional security.  Company can use a public cloud to interact with the clients but keep their data secured within a private cloud.
14. Project Phase Typical Cost Categories PLANNING AND DESIGN Planning end solution Internal and external resources Pilot and proof of concept IMPLEMENTATION software, hardware and licensing fees consulting cost development and testing cost OPERATIONS On going license/maintenace fees operations personnel system admin MAINTENANCE & MODIFICATIONS upgrades or enhancement other incremental expenses
15.  Cloud computing has been gaining increasing attention from businesses of all sizes as a way to obtain secure access .  Midsize companies, those with 100–999 employees, can benefit from cloud-based capabilities.  The variety of applications and approaches to cloud solutions and the different resources companies will make a difference in how these companies implement cloud computing into their business. CLOUD COMPUTING IN MID-SIZED MARKET
16. • Cloud computing holds the potential to dramatically change the businesses that adopt it, even if the technologies are only used internally. • There are some benefits that can potentially change the game for many firms that are willing to be very proactive in managing potential downside. IS CLOUD COMPUTING A GOOD OPTION FOR KEECO ??
17. VARIOUS SERVICE PROVIDERS THAT KEECO CAN CONSIDER FOR CLOUD COMPUTING  Akamai  Amazon  Areti Internet  Enki  Fortress ITX  Joyent  Layered Technologies  Rackspace  Salesforce.com  Exostart  Terremark  XCalibre
18. Constraints in implementing cloud at KEECO` How to over come it ?? • The main constraint of KEECO is that a cloud computing should be accessible to and from china. • The service providers that gives access to china are ExoStart Joyent
19. * Joyent is a global cloud computing software and service provider that offers an integrated suite of software and services designed for enterprises.  JoyentCloud delivers virtual machines, server hosting, and cloud services in a unique cloud architecture designed for rapid scaling and high performance production apps.  Joyent Smart Machines run inside container-based virtualization.
20.  Exostart’s Forum Pass is a cloud-based, enterprise- class, complete B2B project collaboration service offering. It’s built on the Microsoft SharePoint 2010 platform.  What truly makes Forum Pass unique is its security. How does ExoStart work??
21. These advanced capabilities allow Forum Pass to promote: File sharing and document management Secure joint proposal management Net meetings and concurrent/real- time working environments. Process management and routing Product design and collaboration
22. CONCLUSION O Thus from my study and research Cloud is not a matter if it fits small business or not, cloud is a matter of time. O Cloud computing started mid-2008 and is now growing and developing so in few years from now cloud will not be an option but a MUST specially for small to medium size companies who wishes to stay competitive taking into consideration the cost reduction in terms of network and hardware infrastructure, servers, licenses, support etc…………
