Advantages of Cloud Computing:

Cost effective: Because companies don’t have to purchase equipment and build out and operate a data center, they don’t have to spend significant money on hardware, facilities, utilities and other aspects of operations. With traditional computing, a company can spend millions before it gets any value from its investment in the data center.

Flexibility: Cloud is the flexible facility that can be turned up, down or off depending upon circumstances. For example, a sales promotion might be wildly popular, and capacity can be added quickly to avoid crashing servers and losing sales. When the sale is over, capacity can shrink to reduce costs.

Less environmental impact: With fewer data centers worldwide and more efficient operations, we are collectively having less of an impact on the environment. Companies who use shared resources improve their ‘green’ credentials.

Always-on availability: Most cloud providers are extremely reliable in providing their services, with many maintaining 99.99% uptime. The connection is always on and as long as workers have an Internet connection, they can get to the applications they need from practically anywhere. Some applications even work off-line.

Disadvantages of Cloud Computing:

Data loss - Data loss may occur as a result of an accident: when a disk drive dies without a backup, for instance, or if the owner of encrypted data loses the key that unlocks it. Data can be lost as a result of human error in an unimaginable variety of ways. And, of course, data can be lost due to a malicious attack – a data breach.

Abuse of cloud services - A hacker might also use cloud servers to deploy malware or launch DDoS attacks. Cloud service providers will have to be able to detect abnormal activity and stop it without impeding normal customer operations and the use of software, platforms, and infrastructure.

Data breach - Data breaches can result in the loss of sensitive information – in the well-publicized cases of large retailers Target and Home Depot, personal and credit card information was stolen, along with an equally important asset: the companies’ reputations. The nature of cloud computing, utilizing remote computers performing parallel tasks, leaves it open to malicious infiltration at multiple points, and if an attacker gains control over the master computer, the hypervisor, an organization can be very exposed indeed.

Denial of service attacks - Another old disrupter of online operations, denial of service attacks have been around a long time. Like account hijacking, DoS attacks remain a threat everywhere, but especially in cloud computing with its network of virtual machines, hypervisors, and multiple points of entry. A denial of service attack might diminish service without quite shutting it down, incurring bills from the cloud service for excessive resources used during the attack.

Addressing Cloud Computing Risks:

Work with an expert to assure cloud security on a regular basis, either as a consultant for business, or perform third-party audits to ensure that Cloud Service Provider is compliant with industry’s standards of security.

Implement end-to-end encryption. Ensure the Cloud Service Provider has solutions for encrypting data not only in transit, which is standard, but when the data is at rest. For the lowest risk, your data should be encrypted prior to upload, while it is in storage and can only be decrypted with the correct encryption key. Ensure secure data transmission. Data must be mobile, and it must be secure as it travels, so secure the data by using an encrypted and secured communication protocol like SSL/TLS.

Use up-to-date systems and in-house applications. Cloud Service Provider has an impossible job if they have to support outdated software with known security risks. Outdated operating systems, like Windows XP and outdated browsers, like Internet Explorer 7, put you at risk even if you have taken all other appropriate defensive action.

Explanation / Answer

The post lists the various incentives and pitfalls attached to the use of cloud computing.

The cloud computing is a new trend witnessed in the IT industry that is enabling enterprises to better adapt to changes in the demand of their product and services without any additional infrastructural overhead.
- Though there are many advantages taken notice of in the post like data availability, environmental benefits and less cost etc. But the most critical part of the cloud services are how robust are those promises.
- Enterprises always desires the benefits that cloud computing offers but not at the grave risk of data loss and theft or complete shut down of services either due to DDoS or DoS. The very use of cloud computing do leaves open spaces in terms of data security and their inability to enforce latest in-house applications, which means grave risks for the enterprises in the future.
- One major thing that can be summed from the whole post is that Cloud Computing is still at the level of infancy and enterprises needs to carefully do the risk assessments before getting ahead with it.
