Widely used by many companies today, a public cloud is a computing system where a service provider creates resources, including various work related applications and data storage schemes, which can be accessed via the Internet by subscribing users. Public cloud is typically sold on a consumption based “pay-per usage” system. Whereas private cloud systems are operated and administered by the organisation it serves, public clouds implement the sharing of resources and numerous computing services among potentially thousands of internet users. Today there is a plethora of providers targeting consumer and/or business markets – the most well-known examples being Amazon Web Services (AWS), or Microsoft’s Azure or Apple’s iCloud.
For businesses there are many challenges to face when selecting a public cloud provider including data protection and the capability for administrative control provided. Today, the advancements in virtualisation and service provider management tools means that offerings are now offered by regional and internationally based providers. For the business Cloud Consumer this offers a greater choice of provider – all the advantages of public cloud computing but retaining whatever level of local support and enhanced service level agreements they have become accustomed to.
How Public Cloud Works
The whole world is now consumed in cyber space and as more and more people use the internet every day, cloud computing has become a viable reality for all market sectors. A new and interesting way of managing this rapid growth is through use of a public cloud. These services use a variety of virtualisation technologies to provide server operating systems. These virtualisation technologies range from the open source Xen Server through to VMWare and Linux KVM, networking is also ‘virtual’ with many providers delivering connectivity through virtual switches hosted on the cloud. This mixture of virtual technologies provide a familiar operating system environment utilising products such as Microsoft Windows server through to Red hat Linux and a plethora of others.
Public cloud computing uses the same principles of hosting but in a purely virtual form, meaning all the services provided are intangible – or can’t be traced back to a single box or node. Therefore there is no need for businesses to use hard drives for storing data because the system offers organisations rapidly expandable and modular virtual data storage options. This enables thousands of users to store their information in the cloud. This kind of data flexibility would be impossible with the use of a individual servers and hard drives. These services, therefore promise to revolutionise how companies store all their business data and information.

Challenges Using Public Cloud Systems
Companies exploring using public cloud services are presented a set of challenges. Some of the challenges that you might face include:
Bad experience due to inadequate internet speeds
If you want to succeed in a public cloud computing service, make sure that you have a reliable internet provider and connectivity speeds which permits fast transfer of your typical file sizes. Sharing and uploading of files is processed through the internet thus the better the speed the faster it is for you to connect to the servers data system. If you have a poor internet connection, you will find data sharing and uploading in public cloud services a very slow and painstaking process.
Another challenge in using public cloud services is the issue of reliability. Before subscribing to a public cloud computing system, do some inquiries centred around service level agreements if they can guarantee that their system can operate 24/7 and are designed across multiple server nodes or even multiple locations. Many of your company’s operations will rely heavily on the services provided by the public cloud system thus if you subscribe to an unstable cloud service then you may well experience difficulties.
Aside from the two most common challenges that you might face, there are also some risks involved. Here are some of the possible risks in using public cloud:
- Security Issues
- Unsure Operation and accessibility
- Difficult to retrieve back data
- Long term reliability
- Poor Quality Support
