Cloud Computing

  1. 1. CLOUD COMPUTING: IMPACT ON BUSINESS Hosted by: SBAI Imane ElYOUSFI Loubna FERTAT Marouane Supervised by: Dr. KABAILI Hind
  2. 2. OUTLINES • Definition of Cloud computing. • Why cloud computing is so important: AWS as an example. • Characteristics of Cloud Computing. • Cloud service models: IaaS, Paas, SaaS • Types of Cloud Computing: private, public clouds, hybrid clouds and community cloud. • Impact of Cloud services on Business (Pros and cons). • Effect of cloud computing on future IT jobs.
  4. 4. DEFINITION OF CLOUD • Cloud computing refers to applications and services that run on a distributed network using virtualized resources and accessed by common Internet protocols and networking standards. • Cloud computing takes the technology, services and applications that are similar to those on the Internet and turns them into a self-service utility.

  5. 5. DEFINITION OF CLOUD Cloud Virtualization : • Cloud Computing virtualizes systems by pooling and sharing resources. • Systems and storage can be provisioned as needed from a centralized infrastructure . Abstraction : • Cloud Computing abstracts the details of system implementation from users and developers . • Applications : run on physical systems that aren’t specified . • Data : is stored in locations that are unknown. • Administration of systems: is outsourced to others .
  7. 7. IMPORTANCE OF CLOUD • Cloud computing is about storing the files and resources on a server and then accessing it from anywhere in the world via Internet. • The need for physical space and high energy costs will – and already do – increase that cloud computing is a global reality.
  8. 8. IMPORTANCE OF CLOUD Cost Savings There is a better use of server resources, which, once working together, allow the full use of memory, processing, disk space, etc. Speed Everything in cloud computing is connected and allows immediate interaction. Changes are applied better use of time is also felt. Security Computer is used to carry out all the important work. cloud computing is one of the most secure ways to store all of your businesses lead and sales information.
  9. 9. IMPORTANCE OF CLOUD Almost Unlimited Storage In the cloud computing, you can opt for the unlimited storage plans that do not cost you much. The amount that you pay to your cloud service provider for the unlimited storage is less than what you’d have to pay to buy storage devices. Access your Data Anywhere No need for physical access to the system where you saved the data. All is saved in the cloud, and you can access it from anywhere, anytime via Internet.
  10. 10. EXAMPLE OF AMAZON WEB SERVICES • Amazon Web Services has been the frontrunner in the cloud computing race for years, and it doesn't seem to be slowing down. • AWS continues to make moves to keep its customers happy and entice enterprise IT, and it has an array of cloud services that gives customers loads of options to best fit their IT environments. • « Amazon Web Services continues to drink other IT titans' milkshake in the cloud. » • Other vendors, such as Oracle and Microsoft, continue to work to compete and fight their way to the top. • AWS made number one on the Top 10 cloud computing providers list at for 2010, 2011 and 2012.
  12. 12. CHARACTERISTICS OF CLOUD COMPUTING • On-demand self-service: Users are able to provision cloud computing resources without requiring human interaction, mostly done though a web-based self-service portal (management console). • Broad network access: Cloud computing resources are accessible over the network, supporting heterogeneous client platforms such as mobile devices and workstations. • Resource pooling: Service multiple customers from the same physical resources, by securely separating the resources on logical level. • Rapid elasticity: Resources are provisioned and released on-demand and/or automated based on triggers or parameters. This will make sure your application will have exactly the capacity it needs at any point of time. • Measured service: Resource usage are monitored, measured, and reported (billed) transparently based on utilization. In short, pay for use.
  14. 14. CLOUD SERVICE MODELS self-service models for: Accessing and monitoring. Managing remote datacenter infrastructures and Storage. Networking, and networking services (e.g. firewalls). With SaaS, it’s easy for enterprises to streamline their maintenance and support, because everything can be managed by vendors: applications, runtime, data, middleware, OSes, virtualization, servers, storage and networking. With this technology, enterprise operations, or a third-party provider, can: Manage OSes, virtualization, servers, storage, networking, and the PaaS software itself. The user has the possibility of creating, of deploying on an infrastructure his own applications.

  16. 16. CLOUD COMPUTING MODELS Software as a Service Platform as a Service Infrastructure as a Service
  18. 18. PRIVATE, PUBLIC, HYBRID & COMMUNITY CLOUD PUBLIC • Allows systems and services to be easily accessible to the general public. • Less secure because of its openness. PRIVATE • Allows systems and services to be accessible within an organization. • It offers increased security because of its private nature . HYBRID • The Hybrid Cloud is mixture of public and private cloud. • The critical activities are performed using private cloud while the non-critical activities are performed using public cloud . • Bridge incompatible clouds and traditional on-premises environments to operate fluidly as one. COMMUNITY • Allows systems and services to be accessible by group of organizations. • Connect and collaborate with customers, partners, and employees. • May be externally or internally hosted by one of the organizations sharing it.
  19. 19. PRIVATE, PUBLIC, HYBRID & COMMUNITY CLOUD Public Cloud: The customer has no visibility and control over where the computing infrastructure is hosted. The computing infrastructure is shared between any organizations.
  20. 20. PRIVATE, PUBLIC, HYBRID & COMMUNITY CLOUD Private Cloud: Private clouds can be expensive with modest economies of scale. This is usually not an option for the average Small-to-Medium sized business and is most typically put to use by large enterprises.
  21. 21. PRIVATE, PUBLIC, HYBRID & COMMUNITY CLOUD Hybrid Cloud: • Allows users to scale computing requirements beyond the private cloud and into the public cloud, a capability called cloud bursting. • The goal of hybrid cloud is to create a unified, automated, scalable environment that takes advantage of all that a public cloud infrastructure can provide while still maintaining control over mission- critical data.
  23. 23. ADVANTAGES Economies of Scale: Lower variable expenses that companies can achieve themselves. 10’ s of millions of dollars saved with first 12 apps migrated to AWS Saved 34 millions dollars on SmartHub applications 50% reduction in analytics costs
  24. 24. ADVANTAGES Elastic capacity: No need to guess capacity requirements and over prevision
  25. 25. ADVANTAGES Speed & Agility: Infrastructures are provided in minutes not in weeks or months. Quick respond to business needs through high-capacity remote servers. We can double the server’s capacity in 20 seconds. We reduced application deployment’s time from 2 weeks to 3 days. Time to deploy went from weeks to hours
  26. 26. ADVANTAGES Focus on business: Allows companies to devote their resources and mindshare to the core business. Reduced development and test environment costs. “We have a 5 person operations team’’ Export operational data to Amazon Redshift for analytics. 2 times faster quieries at ½ the cost
  27. 27. ADVANTAGES •Expand firm’s global presence SoftLayer has points of presence (POPs). Each of these data centers is connected through high speed fiber allowing companies to coordinate their global infrastructure. Increased collaboration Teams can access, edit and share documents anytime, from anywhere, they’re able to do more together, and do it better. Cloud-based workflow and file sharing apps give them full visibility of their collaborations. Environmentally friendly While the above points spell out the benefits of cloud computing for your business, moving to the cloud isn’t an entirely selfish act. The environment gets a little love too.
  28. 28. DOWNSIDE Prone to Attack Storing information in the cloud could make companies vulnerable to external hack attacks and threats. Nothing on the Internet is completely secure and hence, there is always the lurking possibility of stealth of sensitive data. Performance on shared infrastructure can be inconsistent: It’s a given that when companies share infrastructure with others, they might be impacted by noisy neighbors. Cloud computing may not be the right fit for all workloads: Not all workloads are ready for the cloud. Some workloads have very specific performance and security requirements. Companies need to evaluate their workloads carefully to determine whether they are appropriate for the cloud.
  29. 29. DOWNSIDE The legal framework It is not clear where data are stored. In addition, there is no physical access to these data. The cost of cloud The costs of transfers must also be considered when companies are migrating their data from cloud to cloud. The collaborators’ productivity Companies have to make sure that collaborators understand that moving to cloud technology is not outsourcing or a way to cut jobs, but rather an opportunity.
  31. 31. EFFECTS OF CLOUD COMPUTING ON IT JOBS The authors argue that digital innovation has “changed how the economic pie is distributed, and here the news is not good for the median worker. As technology races ahead, it can leave many people behind. Workers whose skills have been mastered by computers have less to offer the job market, and see their wages and prospects shrink.”
  32. 32. EFFECTS OF CLOUD COMPUTING ON IT JOBS BusinessAnalysts in IT User requirements & cloud- based vendors must still be selected, and applications must still be integrated into business processes. IT Project Managers More systems can be implemented with less internal IT resources. Security Specialists Increased cloud vendors means more openings through company firewalls and potentially the need for manual procedures to manage user access to cloud-based applications.
  33. 33. EFFECTS OF CLOUD COMPUTING ON IT JOBS Cloud Sales Executive Develop and grow outsourced cloud business with C-level professionals in midsize and enterprise-level customers. Cloud Broker Third-party individual or business that acts as an intermediary between the purchaser of a cloud computing service and the sellers of that service. He acts as an intermediary between two or more parties during negotiations. Cloud Consultant Conduct technical studies and evaluations of business area requirements and recommends to IT management appropriate cloud technology options.
