Cloud Computing
- 1. IT Skills
- 2. • It is the delivery of on-demand computing service over the Internet • It is a set of tools provided on the internet that let us spend less time managing and more time creating.
- 3. Types of Cloud Computing Cloud Computing is divided into two wide categories : 1) Deployment Model 2) Service Model Deployment Model There are three types of cloud on basis of deployment model : Public cloud Private cloud Hybrid cloud
- 4. 2 – Private Cloud • The cloud infrastructure is exclusively operated by a single organization. • It can be managed by the organization or a third party 3. Hybrid Cloud Contains features of both Public and Private Cloud. One cloud is managed by the user (typically called “private cloud”) and at least one cloud is managed by a third party (typically called “public cloud”).
- 6. PaaS: • Platform as-a-service • PaaS provides cloud platforms and run time environment for developing ,testing & managing applications so that developers can build applications over the internet . • Used by Software Developers SaaS: • Software as-a-service • A software delivery model where software and apps are hosted and made available over the internet. • It is hosted & managed by CSPs (Cloud Service Providers) • It is used by end customers /users
- 10. ADVANTAGES 1. Cost efficiency : Cloud computing is probably the most cost-efficient method to use, maintain and upgrade .It can significantly lower the company’s IT expenses because • No dedicated space for servers is required • No need to deploy experts for software and hardware maintenance • Allows Pay-as-you-go 2. Unlimited storage capacity : The cloud gives you almost unlimited storage capacity.
- 11. ADVANTAGES 3. Backup and Recovery : Once data is stored in the cloud, we can backup and restore it with relatively much ease than storing the same on a physical device. 4. Easy Access to Information : We can access the data on cloud from anywhere & at anytime where there is an Internet connection. This feature has add ease to our lives.
- 12. Disadvantages of Cloud Computing 1) NETWORK CONNECTION DEPENDENCY In order to reap the benefits of cloud computing, an active internet connection is mandatory. Unfortunately, there is no way to get around this fact because we need a network in order to send files to the cloud and retrieve them. 2) Limited Features Many web-based applications aren't as full-featured as their desktop-based versions. For example, we can do a lot more with Desktop PowerPoint than with cloud-based Powerpoint . The basics are similar, but the cloud application lacks many of PowerPoint's advanced features.
- 13. 3) Risk of data confidentiality There is always a risk that user data can be accessed by other people. Due to the high volume of data stored on the cloud, anybody using cloud services is potentially at risk of cyberattacks. 4) Vendor lock-in It refers to a situation where the cost of switching to a different vendor (Cloud Service Provider) is so high that the customer is essentially stuck with the original vendor.
- 15. A powerful cloud based version of Microsoft office. It gives us the ability to access, create and edit Word, Powerpoint, and other documents from multiple devices and locations. This greatly enhances our productivity as we can work from anywhere in the world. 1) Office 365 2) Video Streaming Services Netflix is the world’s leading internet television network It uses cloud computing for nearly all its computing and storage needs.
- 16. 3 ) Google Assistant It is a cloud-based natural language intelligent bot. It uses the computing capabilities of the cloud to provide personalized user experiences. Google Assistant can send a text, set alarms & reminders, and instantly look up emails. . So the next time you say Hey Google just remember that there is a cloud-based AI solution behind it .
- 17. Social Media is the most popular and often overlooked application of cloud computing. Facebook, LinkedIn, Twitter, and many other social networking sites also use cloud computing because it provides powerful hosting solution to manage and store data in real-time . 4. Social Media Other examples include Gmail, Google Drive and other Google Apps
- 18. Instead of buying, owning, and maintaining physical data centers and servers we can access a wide range of technology services on an as- needed basis from a cloud provider like we mentioned above. Organizations of every size & type are using the cloud for a wide variety of purposes such as data backup, software devp. and testing etc. Organizations have moved to cloud platforms for better scalability, mobility and security.
