Cloud computing is using network-based services, typically on the Internet, instead of using local hardware and software infrastructure for both business and personal use. In the last few years, cloud computing has become extremely popular, yet few people fully understand all of the advantages and disadvantages of cloud computing, so here goes.
The Advantages of Cloud Computing :
Cost: Because the costs of cloud computing is significantly less than the alternative (purchasing, licensing, and maintaining local infrastructure), small companies and even start-ups can more easily afford cloud computing. In fact, many start-ups exist only because of the low costs of cloud computing. Furthermore, many companies prefer using cloud computing when testing the market and profitability of a new product, thus minimizing the risks of expensive purchases on products that are not proven to succeed.
Flexibility: With cloud computing, resources are very scalable. For instance, disk space store is virtually unlimited, processing power can be quickly increased or decreased as needs change, and even the servers are resilient/redundant, if there are hardware failures.
Quick and Easy: Cloud computing makes backup and recovery both quick and easy. Setting up cloud computing is also quick and easy. Even the convenience of having access almost anywhere and anytime makes usage a quick and easy too.
Security: Typically, cloud computing servers have much more security than local servers. Cloud computing networks are more likely to continuously monitor hacking attempts and patch security issues as soon as possible.
The Disadvantages of Cloud Computing
Outages/Control: As with all computing, there are outages. The difference with cloud computing outages is that they can be massive disruptions that can affect a much larger number of people and applications. Thus, smaller applications would have a lower priority to be resolved. As a result, cloud computing users and clients have limited or no control over the cloud computing resources.
Security: Cloud computing typically does not guarantee security of applications or privacy of data. Additionally, using a cloud computing service increases the likelihood of being noticed and thus more prone to attacks by hackers.
Conclusion: As you can see, cloud computing has several major advantages, while only two relatively minor disadvantages. As with all things business, cloud computing saves consumers and companies a lot of time and money, thus cloud computing will remain an integral part for even the most mundane businesses.
