Cloud Computing: What Are the Advantages and Disadvantages, and Is It Safe?

Table of Contents

Remember that cloud computing is defined as shared computing resources that have been virtualized and are accessible as a service via an APL.

The Advantages

1- Expenses/capital outlays

If cloud computing is ideal for your business, you’ll save a lot of money on infrastructure, support equipment, and communication. These expenses are owned by the vendors and/or service providers who charge consumers a utility or user type fee.

2- The ability to scale

The ongoing need to install additional technology to keep up with the expanding demand for accessing, storing, and analysing information by both internal and external users is one of IT’s main problems. In the data centre, for example, expanding servers is a key cost concern (actually power for the data centre is the number one issue, but it is related to the growing need for items like servers). Because cloud computing is virtual, it is possible to scale up or down equipment/infrastructure as needs change.

3- Start – up

All one needs to do is “dial” in to the cloud because it (theoretically) includes the infrastructure and apps. Rather of installing, testing, and then granting access to the appropriate user community, programmes may be used right away. (Training is taken as a given.)

4-Professional Applications

Again, the cloud (really, the vendors and/or service providers) delivers multiple business apps for each user that is their customer via contracts (Service Level Agreements – SLAs). Enterprises, like scale, merely need to know which apps they require to operate their business and what is really supplied in order to have access to numerous business applications. (It is believed that training is continuous.)

5- Adaptability

Because cloud computing is a virtual service, a user can change the apps, quantity of bandwidth, or number of users on a regular basis by amending his user contract and raising or lowering fees at a set rate or factor.

The Disadvantages

1- SLAs (Service Level Agreements)

This is the most difficult and crucial one. SLAs may be complicated, and it is up to the user to fully comprehend and establish all criteria, as well as to understand what they are getting in terms of support, performance, security, and so on. Quality of service is an excellent example; one should know what is supplied and what recourses are available if the claimed quality is not met.

2- Performance

Performance assurances are normally included in SLA documents, but I’ve highlighted this one since it’s vital to sustain both internal and external users’ performance (uptime). Determine if the performance promise is an average or just during peak periods, as opposed to a “uniform” performance. If your performance is harmed, it may have a negative influence on a variety of things, including revenue and your company’s reputation.

3-Vendors

Not every merchant is made equal! Many vendors claim to provide cloud computing, but in fact, they are just delivering a certain service or application, or worse, they are merely acting as a middleman with no added value. As I mentioned in my last essay, there is a distinction to be made between cloud computing and hosted services, managed services, or what appears to be some type of virtualization. My best recommendation is to contact reference customers and see if they can mimic what you want from the cloud.

4-Security

We all know the internet has security vulnerabilities, and because the cloud makes use of the internet as well as application infrastructure and support, users should be aware of the possibility for new attacks and risk exposure. Because not all security risks are recognised and new ones may appear, it’s critical to factor your firm’s risk tolerance into any choice to switch to cloud computing.

5-IT Recruiting

If you use the cloud, be sure you understand the vendor personnel that is available to serve your needs as well as the needs of hundreds of other people who use their cloud. Some suppliers outsource staffing, and some of the people they hire may not be as good as your own internal team. Inquire if the possible service provider has the necessary training to support the apps you’ve requested.

As I’ve always said, know your IT organization’s and lines of business’s strategies and consider if the “pros” outweigh the “cons” of cloud computing. It’s important to remember that cloud computing has a variety of benefits and drawbacks; don’t be seduced just by cost savings.

The answer will very certainly be something in the “between,” i.e. a hybrid type of cloud computing.

In terms of cloud computing and security,

Chenxi Wang, Ph.D. wrote an essay for Forrester titled “A Close Look At Cloud Computing Security.” Wang claims “While cloud computing has numerous advantages, businesses should not hop on board without a compelling business case and a thorough grasp of the security, privacy, compliance, and legal implications. Making the cloud service function like your own IT security department and finding ways to safeguard and maximise your cloud assets are the ultimate goals of a successful assessment plan that covers these topics.”

Data protection, disaster recovery, and identity management are some of the areas covered by security, according to Forrester, who recommends doing a security assessment of a potential cloud provider to verify what level of security is actually given.

In terms of compliance, the user should consider how the cloud may or may not affect their compliance needs.

For legal and contractual reasons, Forrester recommends that both the user and the supplier understand who owns/is accountable for what (the data, the infrastructure, etc.)
