Cloud computing

  1. 1. IN A NEW AGE- 1
  2. 2. 2
  3. 3.  “Cloud” is a metaphor for the internet. “Cloud computing” is a phrase that is being used today to describe the act of storing, accessing, and sharing data, applications, and computing power in cyberspace. 3
  4. 4.  Cost Efficient - Cloud computing is probably the most cost efficient method to use, maintain and upgrade. The cloud is available at much cheaper rates and hence, can significantly lower the company’s IT expenses.  Almost Unlimited Storage - Storing information in the cloud gives you almost unlimited storage capacity. Hence, you no more need to worry about running out of storage space or increasing your current storage space availability. 4
  5. 5.  Automatic Software Integration – You can customize and integrate your applications as per your preferences.  Easy Access to Information - Once you register yourself in the cloud, you can access the information from anywhere, where there is an Internet connection.  Backup and Recovery - Since all your data is stored in the cloud, backing it up and restoring the same is relatively much easier than storing the same on a physical device. 5
  6. 6. 6
  7. 7.  Technical Issues - Though it is true that information and data on the cloud can be accessed anytime and from anywhere at all, there are times when this system can have some serious dysfunction.  Security in the Cloud - The other major issue while in the cloud is that of security issues. Before adopting this technology, you should know that you will be surrendering all your sensitive information to a third-party cloud service provider.  Prone to Attack - Storing information in the cloud could make your company vulnerable to external hack attacks and threats. As you are well aware, nothing on the Internet is completely secure and hence, there is always the lurking possibility of stealth of sensitive data. 7
  8. 8.  Private cloud - Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally.  Public cloud - A cloud is called a 'Public cloud' when the services are rendered over a network that is open for public use. Technically there is no difference between public and private cloud architecture, however, security consideration may be substantially different. 8
  9. 9.  Community cloud - Community cloud shares infrastructure between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party.  Hybrid cloud - Hybrid cloud is a composition of two or more clouds (private, community or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models. 9

  11. 11.  Users access cloud computing using networked client devices such as desktop computers, tablets and laptops and smart phones.  Some of these devices - cloud clients - rely on cloud computing for all or a majority of their applications so as to be essentially useless without it. 11
  12. 12.  Cloud computing providers offer their services according to several fundamental models.  Infrastructure as a service (IaaS) - In the most basic cloud-service model, providers of IaaS offer computers other resources. For eg:- Firewalls, file-based storage etc.  Platform as a service (PaaS) - in the PaaS model, cloud providers deliver a computing platform typically including an operating system, programming language execution environment, database, and web server. 12
  13. 13.  Software as a service (SaaS) - In the business model using software as a service (SaaS), users are provided access to application software and databases. Cloud providers manage the infrastructure and platforms that run the applications.  Network as a service (NaaS) - It is a category of cloud services where the capability provided to the cloud service user is to use network/transport connectivity services and/or inter-cloud network connectivity services. NaaS involves the optimization of resource allocations by considering network and computing resources as a unified whole. 13
