- 2. Cloud computing is the on-demand delivery of IT resources through the internet with, pay-to-use charges.
- 3. Cloud Computing Role in IT In 2008 Oracle CEO Larry Ellison chastised the whole issue of cloud computing, saying that the term was overused and being applied to everything in the computer world. “The computer industry is the only industry that is more fashion-driven than women’s fashion,” he said to a group of Oracle analysts.
- 4. What cloud computing is and how it is deployed? Cloud computing promises to cut operational and capital costs and, more importantly, let IT departments focus on strategic projects instead of keeping the datacenter running.
- 5. Beauty of cloud computing Another company hosts your application They handle the costs of servers, they manage the software updates, and—depending on how you craft your contract—you pay less for the service. Having someone else host the applications, you need not buy the servers nor pay for the electricity to power and cool them. Convenient for the users they can log in from anywhere
- 6. Beauty of cloud computing - With cloud computing, other companies host your applications
- 7. Cloud Computing Role in IT You may not be able to access your applications and do your work if your service provider internet goes down, e.g. In July 2008, Amazon’s S3 cloud storage service went down for the second time that year. A lot of applications were hosted by the company and all those services could not be accessed until techs could fix the problem. Some applications were down for eight hours. sensitive or proprietary information your company simply may not want to store it on someone's else machine
- 8. Application Integration Issues 1) Security 2) Network Latency 3) Choosing the Right Architecture 4) Data Governance Questions 5) Cloud Integration Anti-Patterns 6) On-Premise Integrations
- 9. Cloud Components 1. clients, 2. datacenter, 3. distributed servers
- 10. Cloud Component - Client • Mobile Mobile devices include smartphones, like a Blackberry, Windows Mobile Smartphone, or an iPhone. • Thin Clients are computers that do not have internal hard drives, but rather let the server do all the work, but then display the information. • Thick This type of client is a regular computer, using a web browser like Firefox or Internet Explorer to connect to the cloud. Clients are the devices that the end users interact with, to manage their information on the cloud.
- 11. Cloud Component – Datacenter systems for storing, sharing, accessing, and processing data across the organization physical infrastructure to support data processing and data communication Utilities such as cooling, electricity, network access, and uninterruptible power supplies (UPS) collection of servers where the application to which you subscribe is housed
- 12. Cloud Component – Distributed Server e.g. Amazon Failure can be handled Flexible in context of space • Thick This type of client is a regular computer, using a web browser like Firefox or Internet Explorer to connect to the cloud. Flexibility in options and security
- 13. Cloud Computing – Benefits • Familiarity with the World Wide Web Most workers have access to a computer and know how to use it on the World Wide Web. As such, the learning curve for using external applications can be much smaller. • Smaller staff IT systems require the overhead of salaries, benefits, insurance, and building space. The ability to farm out applications reduces the need for as much IT staff. • Customization Older applications were difficult to customize and required tinkering with the code. SaaS applications are much easier to customize and can give an organization exactly what they want.
- 14. Cloud Computing – Benefits • Web reliability We talked earlier about how the World Wide Web can be seen as a source of failure. And while that is sporadically true, the fact of the matter is that the Web is generally quite reliable. • Security Secure Sockets Layer (SSL) is widely used and trusted. This allows customers to reach their applications securely without having to employ complex back-end configurations, like virtual private networks (VPNs). • More bandwidth Bandwidth has increased greatly in recent months and quality of service improvements are helping data flow. This will allow organizations to trust that they can access their applications with low latencies and good speeds.
- 15. Cloud Computing – Challenges • Privacy and Security • Client incomprehension • Data Security • Address growing integration complexities • Reliability and availability • Dependency on Service Providers
