Cloud based computing system is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Cloud computing is a concept put forward by Google, which is a new way to play with computer and Internet. It is a kind of computing which is based on the internet. Shared information is provided to computers and other devices on demand, like the electricity grid. Some of the benefits received from using cloud include efficient operations, large storage capacity, and accessibility.
A typical cloud computing provider provides a common business online application which is accessed
from another Web service or Web browser as software, and software and data are stored on the server. A
paramount element of cloud computing is customization and the creation of a user-defined experience. Cloud computing, on the other hand, eases operations by using cloud-based software which only requires an internet connection to function without relying on a computer’s storage.
Cloud-based systems can store from 10 to 100 million gigabytes of data that can even be accessed via phone as long as an internet connection is available. The large storage capacity and accessibility of data make the cloud an excellent backup for a company’s data in case physical storage devices are lost or damaged. This article will try to explain the impact that cloud based computing brings to the business world by offering the examples of three widely accepted cloud services.
Key Technology of Cloud-Based Computing
Cloud-based computing system provides the most reliable and secure data storage center. Users no longer have to worry about data loss, virus attack and other problems. Because the world’s most professional team are helping you manage information, and the world’s most advanced data center is helping you save the data. The cloud computing has the minimum requirement on the client devices, which makes it useful and most convenient. In addition, you can easily realize sharing data and application between different devices. For network applications in the cloud model, data is only one, saved in the “cloud”, on the other side. You only need all the electronic equipment connected to the Internet to simultaneously access and use the same
data. Cloud based computing provides us almost infinite possibility using the Internet. Personal computer or other electronic devices can not provide unlimited storage space and computing power, but in the “cloud” the other side, by the thousands, tens of thousands or even more servers composed of large clusters this can easily be done. Personal and individual devices is limited, but the potential of cloud computing is nearly limitless.
- Data Storage: Cloud-based computing system stores data in large scale distributed systems in order to provide the most reliable and secure data storage center. Users no longer have to worry about data loss, virus attack and other problems. One of the most important data storage technology of cloud computing is Google File System (GFS). It is constituted by a Master and a large block of servers. Master stores all the Meta data of file system including namespace, access controlling file block information, the file block location information etc. GFS file are cut into 64MB blocks for storage.
- Data Management: Cloud-based computing system has to process and analyze large data sets as to provide high efficient service. Data management technology should manage large data sets with high efficiency. What’s more, how to find specific data in large data sets is also a key problem in data management.
- Programming Model: In order to make customer enjoy cloud computing service more conveniently, programming model in cloud-based computing must be very simple. Nowadays, most cloud
computing systems Map Reduce programming model.
While using cloud-based system comes with a lot of benefits, there are some downsides to it especially when there are technical problems like power outages, computer problems, and slow internet connections. Files and processes dependent on cloud-based systems would be inaccessible and disrupted when an internet signal is lost. A stable connection with the internet is needed if not the user ends up getting stuck trying to access a file. Just like every thing else, Cloud isn’t the most secure storage site since anything on the internet can be accessed by hackers. Safety measures like strong passwords, firewalls, data encryption, and role-based access control can help solve privacy issues with the latter focusing on preventing inside job leaks.
Here, are the gains and losses of cloud-based software systems that will enable you decide if it’s right for your business.
- The cloud-based software systems provide tools that speed up the accomplishment of office tasks and prevent errors as well. It ensures quality efficient operations.
- Cloud-based software systems do not require installing or inserting additional components (e.g hard drives, flash drive or disc) though an internet connection is necessary.
- Most cloud-based software systems today apply automatic updates without customer intervention, making hassle free for users to gain access to the software’s latest features.
- There are some technical problems such as power outages, computer problems, slow internet connection may affect your cloud-based software usage.
- While using a cloud-based software makes your business data accessible to you and your employees, it also makes your data accessible to hackers, making it vulnerable to security breaches such as data loss, data leakage, and account hijacking among others. So do well to know your privacy and security risks.
