Pros and cons of cloud computing – an in depth look

pros and cons of cloud computing

Everywhere you look within the tech sector, the pros and cons of cloud computing are being discussed. As more and more companies and teams make the move to the cloud, the debate rages on.

Some people are fully behind the cloud revolution, while others are still weighing up the pros and cons of cloud computing for their business.

On one hand, those looking on the pro side point to cloud computing representing the future of all IT systems, capable of saving money and office space for companies.

However, some believe it to be a fad that will eventually peter out. The majority of the evidence and an analysis of the pros and cons of cloud computing would suggest otherwise, however.

Pros of cloud computing

Quick deployment

For many small and medium businesses looking at the pros and cons of cloud computing, it’s likely that they don’t have huge IT departments or massive teams of developers able to maintain their own servers. Cloud hosting allows even the smallest of businesses and even individuals set up and maintain servers in minutes.

Managing large data centers is not within the budgets or possibilities of most companies. Their time is often much better spent focusing on the core of their business and cloud computing allows them to do that.

Cost

Out of all the facts relating to the pros and cons of cloud computing, the cost argument perhaps holds the strongest weight. The cost of running your databases, websites and apps is significantly less than traditional methods. This is because they don’t have to physically maintain any servers.

The cloud is available at much cheaper rates and hence, can significantly lower a company’s IT expenses. Upgrade costs will also end up being lower as there is no hardware to replace.

Backups

One of the major advantages of the cloud is that it offers the ability to store information in a complex network of servers rather than on any hardware device. What that means is that you don’t have to worry about saving all your files on a disk, they can be maintained and secured easily and quickly online.

Programmes like Google Docs are based on cloud technology, as they can automatically save and store information without the user having to physically store it on their hardware.

‘Unlimited’ storage

While not technically unlimited, the amount of storage you can use is a key point in the pros and cons of cloud computing. The cloud relies on making use of the vast array of space available in computers around the world, so in theory there is endless capability in terms of storage.

Scalability

Due to IaaS (Infrastructure as a Service), you can quickly build out new infrastructure to support new applications. As the load on your application gets bigger you can scale by provisioning new servers. If you need to increase the size of your servers to support loads that cannot scale horizontally, you can provision larger servers to support the increased demands.

Cons of cloud computing

The pros and cons of cloud computing may well be one sided, but there are also reasons why the cloud may not be for you.

Security

In theory, making use of cloud hosting means a third party shares access to your data. While the majority of what we do on the internet today involved third parties, there are some who believe that they should keep all their data in their own hands. Your cloud infrastructure can be as secure or as insecure as you make it.

Technical Issues

While all hosting solutions are prone to downtime periodically, cloud hosting is part of that group too. As your information on the cloud can be accessed anytime and from anywhere at all, there are times when this system can disfunction.
