What Are the Advantages and Disadvantages of Cloud Computing?

Cloud services are the needs of businesses and industries of all sizes and geographies. The number of respondents adopting cloud in both public and private has increased manifolds. According to a report by Dell, the companies that invest in cloud, mobility, and big data enjoy up to 53% faster revenue growth than their counterparts. More and more organizations are adopting cloud technology to run the business effectively, to serve their customers in a better way and to overall increase their margin of profit.

Benefits of Cloud Computing

Benefits of Cloud Computing

Here is the detailed list of various benefits offered by cloud computing:

  1. Cost-effective: The cost of hardware and equipment is low and these services are free from capital expenditure. The organizations need not have large IT teams to handle and maintain the cloud data centre operations. The maintenance cost is also low and the occurrence of downtime is also less which means the organizations need not spend a huge amount of money for fixing potential issues. Cloud computing works on the principle of pay-as-you-go, which means you need to pay money only for the services that you use, and you need not invest in additional features that do not serve you. Companies need to pay for servers and infrastructure as and when needed. More services can be commissioned for times of need and the services not being used can be de-provisioned. This further cuts down the expenditure. Owing to the ROI of these technologies, the return is much higher than the costs.
  2. Scalability: Using a cloud service provides companies with an option to scale up or down their IT departments according to their business needs and requirements. You can upgrade the capacity of your cloud without investing in physical infrastructure. Hence these services are ideal for companies with volatile bandwidth demands. The cloud computing service provider handles the expensive upgrades and their installations. The scalability provided by these services reduces the risks with operational failures and maintenance. This also leads to time-effective solutions as most of the complicated tasks are handled by your cloud service providers. Hence the demands are in alignment with the workloads. An example of the scalability feature of cloud computing is in sales promotion; the capacity can be scaled when the sales promotion is very popular, and when the sale is over, the capacity can be cut down to reduce the cost.
  3. Mobility: For more and better inclusion, cloud services are easily accessible on smartphones and mobile devices. According to a report, over 2.6 billion smartphones are being used around the world for cloud services. It is also beneficial for people staying away from their corporate offices, as they can easily access these services from their point of convenience and keep themselves updated with the clients and their work. Most of the cloud providers offer 24*7 services with an uptime of 99.9%. Even some of the functions are available offline as well, which is highly convenient for the workers and they can access the services from anywhere at any time. Adding to this, all the upgrades and updates are done automatically by the service providers further cutting down the IT costs.
  4. Data security: Data security is a concern for many organizations while adopting cloud-based services. With the increased rate of data theft in organizations, it becomes a priority to secure data, files, and downloads. Cloud services provide encryption of data being shared over multiple networks and data that are stored in the database. The data can be easily restored if something goes down with your device. The data can be deleted from other locations to avoid falling in the wrong hands. Cloud storage providers implement baseline protections for their platforms and the data they process, such as authentication, access control, and encryption.
  5. Disaster recovery: The control system to deal with any situation is a deciding factor for the success of any business. Though many measures are taken to prepare for potential risks that might occur, there are situations that go out of control. A downtime of small duration can severely affect your revenue. Apart from this, data loss is a major concern for all organizations. The data stored in the cloud can be easily restored and recovered even when your physical system goes down. Cloud-based services provide quick and effective data recovery from most of the potential emergency conditions like power outages and natural disasters.
  6. Automatic updates: Your system will be regularly updated by your cloud computing service provider. Hence this saves the trouble of waiting for the system updated to get installed. This also saves the efforts of the IT department to keep a check on the new updates being introduced and install them. Immediate upgrades put new features and functionality provided automatically into workers’ control to make them more productive. Software enhancements are typically released quite frequently unlike the homegrown or purchased software that might have major new releases only once a year or so and take significant time to roll out.
  7. Enhanced collaboration: For businesses operating with a large number of employees, collaboration among them is a priority. Cloud computing facilitates this process. The members of a team can easily and securely view and share the data across a cloud-based platform. To enhance the engagement of the employees, some of these services provide social spaces to connect the employees. The cloud services authorize a diverse group of people virtually and allow them to share information through shared storage. If you are working on a project that is spread across different locations, you could use cloud computing to give employees, clients and third parties access to the same files. You could also choose from the different cloud computing models to make it easy for you to share your records with your managers and higher authority.

Disadvantages of cloud computing

Every technology has a positive and a negative side and both must be considered before adopting it. Though cloud computing is a huge success and it boasts of many reliable features, but there are some factors that might create a problem for your company. Here, we discuss some of the downsides of cloud computing and how it affects the organizations:

  1. Downtime: Good internet connectivity is a must in cloud computing. The cloud computing service provider may face power outage, internet connectivity loss, or service maintenance that might affect your process. If your internet speed is slow, it might affect the process adversely, since most of the services are online. Other than the internet, there is no other way to access data on the cloud, so there is a lot of dependency on internet connectivity. You must have a reliable and consistent internet service to operate smoothly with the cloud. 
  2. Lower bandwidth: Many cloud service providers limit the bandwidth range of usage. If the need occurs to expand the bandwidth, then it might increase the cost.
  3. Limited control: Cloud services are completely managed and owned by service providers operating remotely. Hence the employees have limited control over backend features.
  4. Security threat in the cloud: Since all of your data is available online with the cloud, it increases the possibility of data theft. You should be well aware of the fact that all your company's sensitive information is being shared with a third-party cloud computing service provider. Thus it should be trustworthy enough since hackers might have accessed this information. Though the cloud computing vendors ensures that their services have sophisticated data security systems, but there have been many occurrences of data breaches via hacking, a disgruntled employee, or careless username/password security.
  5. Vendor lock-in: Your company might face some serious challenges while migrating from one cloud computing vendor to another. It might lead to configuration complexities, support issues, and hence additional charges.
