Presentation on cloud computing
- 2. Introduction What is cloud computing How cloud computing works Uses of cloud computing How cloud computing stores data Factors affecting cloud computing Pros and Cons of cloud computing Building blocks of cloud computing
- 3. Cloud computing is where computing resources are stored in a virtual online “cloud” rather than a local desktop or organization data center.
- 4. • Cloud Computing is a general term used to describe a new class of network based computing that takes place over the internet. • Basically a step on from utility components. • Using the internet for communication and transport provide hardware , software and networking services to clients.
- 6. It helps us to use applications without installation We access the personal files and data from any computer with internet access. This technology allows much more efficient computation by centralizing storage, memory and processing
- 9. There are two major factors that effect cloud computing services: Usage fees Bandwidth caps
- 10. PROS CONS Reduces IT costs security Increase processing power privacy Allows us to access our files anywhere Usage fees Uses a moderately priced device Bandwidth caps
- 11. There are three building blocks of cloud computing :- SAAS (Software as a service) PAAS (Platform as a service) IAAS (Infrastructure as a service)
- 12. SaaS is a cloud computing layer most people have interacted with one and are likely to use in their day to day lives . Software as a service is where computing applications are accessed through the internet . SaaS eliminates the need to download ,install and run applications on local computers. These applications are managed by a third party vendor.. Example: Google docs.
- 13. A one to many model is used for software delivery. Software management is done from a centralized location. Access to the commercial application is gained via the internet. The end users need not worry about software patches and upgrades. Application programming interfaces enable integration with other applications.
- 14. No fixed costs Device interdependecy collaborative-allows multiple sharing of information Constant updates
- 15. o The main disadvantage of SaaS is that it’s, limited to browser capabilities. o Another drawback of SaaS is the security concerns that surround it.
- 16. o PaaS is a software environment used to develop and run applications . o PaaS can be defined as a computing platform that enables the creation , testing , and implementation of software easily and quickly without the complexities of buying and maintaining the infrastructure and additional software. Examples: Google app engine , MS Azure and force.com
- 17. Has services that allow testing, development, hosting and maintenance of applications. The platform can be accessed by multiple users. Development support Tools with handle subscription and billing management.
- 18. Cost reduction Streamlined application development and management Increased mobility Reduced technical maintenence
- 19. The main disadvantage of PaaS is its restrictive nature. Despite the fact that it makes the development of online applications easy , developers are restricted to the programming language and tools provided by the PaaS Vendor.
- 20. The final and most fundamental layer of cloud computing is infrastructure as a service, it is sometimes referred to as hardware as a service. In this computing infrastructure, networking and storage are delivered over the internet. An enterprise can purchase the services on demand. Example: Amazon web services IaaS is the most fundamental building block, it covers the areas where PaaS and SaaS do not; making at the ideal solution.
- 21. Resources and infrastructure are distributed as a service. Enables dynamic scaling Multiple users utilize a single piece of hardware.
