Advantages and Disadvantages of Cloud Computing

Cloud Computing, has now made it effortlessly easy for all to access applications and software from the internet. Earlier the software and applications had to be physically installed but not anymore. With the evolution in technology and the feasibility to access beneficial apps off the internet, businesses are reaping huge benefits from cloud computing.

However, along with the advantages cloud computing provides, the disadvantages are pretty evident. There are several advantages to cloud computing, and there are prominent setbacks as well.

Advantages of Cloud Computing

1. Cost Saving

Cloud computing has invariable benefited businesses and organizations to help cut costs. The core strategy of every business is to churn out as much revenue as possible while keeping the expenses at a minimum. With Cloud Computing, you can save substantial capital costs, with zero expense as you don’t need to install applications or in-house servers. With no in-house servers, the operational costs of running and maintaining them are eliminated. If the servers were present physically this would call for massive expenses for maintenance, air conditioning, power, and other associated expenses.

The benefits of associating your business process with the cloud are that you pay for the services, and disengage whenever you don’t need the storage service. Organizations do not need to worry about expending a massive portion of the IT capital for an in-house server.

Often people wonder if it is extremely expensive to afford the cloud, but the fact is that it’s quite convenient even for small businesses to get on the cloud. Cloud services are quite affordable for small businesses as well.

2. Reliability

With the need to cater to a larger diverse audience, comes a massive bout of responsibility as well. The cloud infrastructure has to be very efficient in catering to the needs of several clients and maintain its consistency in its functionality and services. Most cloud service providers assure a guarantees assistance round the clock for all days of the contract and there is always close to 100% availability. You don’t need to worry about server maintenance and if the host server fails, the hosted files can easily be transitioned to other available servers.

3. Manageability

The ordeal of maintaining and dealing with server issues become almost non-existent with cloud services. With opting to venture onto cloud services, businesses will benefit massively for enhanced and structured IT services and the various intricate details of managing the servers. All the services related technicalities are taken care of by the service provider and you will enjoy the luxury of a simple web-based user interface to access your applications, services, and services. Businesses now need not worry about the installation and massive expenditure on setting up a server with all the amenities. The service providers abide by the signed Service-Level-Agreement to ensure timely assistance to your business needs and they guarantee to provide the required service to help you use the cloud-based servers.

4. Strategic Edge

With competitions soaring high, you might be in need of the latest applications to catch up with the rest of the crowd.

Disadvantages of Cloud Computing

1. Downtime

With massive overload on the servers from various clients, the service provider might come up against technical outages. Due to this unavoidable situation, your business could be temporarily sabotaged.

And in case your internet connection is down, you will not be able to access the data, software or applications on the cloud. So basically you are depending on the quality of the internet to access the tools and software, as it is not installed in-house.

2. Security

There is room for imminent risk for your data even though cloud service providers abide by strict confidentiality terms, are industry certified and implement the best security standards. When you seek to use cloud-based technology you are extending your access controls to a third party agent to import critical confidential data from your company onto the cloud. With high levels of security and confidentiality involved, cloud service providers are often faced with security challenges.

The presence of data on the cloud opens up greater risk of data theft as hackers could find loopholes in the framework. Basically your data on the cloud is at a higher risk, than if it was managed in-house.

Hackers could find ways to gain access to data, scan, exploit a loophole and look for vulnerabilities on the cloud server to gain access to the data.

For instance, when you are dealing with a multi-tenant cloud server, the chances of a hacker breaking into your data is quite high, as the server has data stored by multiple users. But the cloud-based servers take enough precautions to prevent data thefts and the likelihood of being hacked is quite less.

3. Vendor Lock-In

Companies might find it a bit of a hassle to change the vendors. Although the cloud service providers assure that it is a breeze to use the cloud and integrate your business needs with them, disengaging and moving to the next vendor is not a forte that’s completely evolved. As the applications that work fine with one platform may not be compatible with another. The transition might pose a risk and the change could be inflexible due to synchronization and support issues.

4. Limited Control

Organizations could have limited access control on the data, tools, and apps as the cloud are controlled by the service provider. It hands over minimal control to the customer, as the access is only limited to the applications, tools, and data that is loaded on the server and no access to the infrastructure itself. The customer may not have access to the key administrative services.


The advantages of cloud computing are way too good, it is quite cost-effective and it is efficient. The drawbacks are incidental and almost negligible. The decision to opt for cloud-based services is great with saving substantial costs with regards to installation and maintenance, reduced downtime, almost negligible manpower involved in monitoring the servers and no collateral investment with regards to the infrastructure required to house the servers in-house.
