Amazon overshadows the competition in the cloud market

The cloud services market is made up of three main models: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Each model of cloud service provides different levels of control, management, and flexibility. Gartner has recently published an article indicating that the IaaS market has grown 31.3% from 2017 to 2018, to total $32.4 billion. According to their research, Amazon is the top vendor, owning nearly half of this sector of the cloud market.

What is IaaS?

IaaS is a cloud-computing offering, in which users can access computing resources such as storage, servers, networks, and operating systems through virtualisation technology. Customers who use IaaS are able to control their own data infrastructure via a dashboard or API. This sector of cloud services has the highest level of flexibility and management control. Traditionally, without IaaS, this is physically managed on-site. Therefore, IaaS can be more cost-efficient and is often on a pay-as-you-go basis.

The IaaS market

The top five IaaS service providers in 2018 include Amazon, Microsoft, Alibaba, Google, and IBM. Together, these five companies account for nearly 77% percent of the IaaS market worldwide. With only five companies owning the majority of the IaaS market share worldwide, there is tough competition for smaller companies who may not have the same scalability as these other giants. However, other companies still take up 23.3% of the market share, which has grown 11.1% since 2017.
