Cloud Computing

Cloud Computing

1. What is it

   • the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.
   • Takes away the need for external storage for example you wont need to use a pen drive

2. Disadvantages

   • •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. You should be aware of the fact that this technology is always prone to outages and other technical issues. Even the best cloud service providers run into this kind of trouble, in spite of keeping up high standards of maintenance. Besides, you will need a very good Internet connection to be logged onto the server at all times. You will invariably be stuck in case of network and connectivity problems.
   • •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. (Security)
     • Prone to attack from Hackers
   • It can be slow

3. Benefits

   • •Cloud computing is probably the most cost efficient method to use, maintain and upgrade. Traditional desktop software costs companies a lot in terms of finance. Adding up the licensing fees for multiple users can prove to be very expensive for the establishment concerned. The cloud, on the other hand, is available at much cheaper rates and hence, can significantly lower the company’s IT expenses. Besides, there are many one-time-payment, pay-as-you-go and other scalable options available, which makes it very reasonable for the company in question.
     • Unlimited storage
     • All externaly stored
   • •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.
   • •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. Furthermore, most cloud service providers are usually competent enough to handle recovery of information. Hence, this makes the entire process of backup and recovery much simpler than other traditional methods of data storage.
   • Cost efficient

4. different types

   • Web-based cloud services. These services let you exploit certain web service functionality, rather than using fully developed applications. For example, it might include an API for Google Maps, or for a service such as one involving payroll or credit card processing
   • vSaaS (Software as a Service). This is the idea of providing a given application to multiple tenants, typically using the browser. SaaS solutions are common in sales, HR, and ERP.
   • Platform as a Service. This is a variant of SaaS. You run your own applications but you do it on the cloud provider’s infrastructure.
   • 4.Utility cloud services. These are virtual storage and server options that organizations can access on demand, even allowing the creation of a virtual data center
   • Managed services. This is perhaps the oldest iteration of cloud solutions. In this scenario, a cloud provider utilizes an application rather than end-users. So, for example, this might include anti-spam services, or even application monitoring services.
   • Service commerce. These types of cloud solutions are a mix of SaaS and managed services. They provide a hub of services which the end-user interacts with. Common implmentations include expense tracking, travel ordering, or even virtual assistant services.

5. cloud storage

   • Your data is protected through redundant storage at multiple physical locations. OAuth and granular access controls form strong, configurable security
