The adoption of cloud computing has quickly become a key driving force for businesses today, as applications are moved out of on-premise data centres in a bid to cut costs and increase agility.
Infrastructure-as-a-service (IaaS) is a model where a third-party provider hosts and maintains core infrastructure, including hardware, software, servers and storage on behalf of a customer. This typically includes the hosting of applications in a highly scalable environment, where customers are only charged for the infrastructure they use.
Early concerns over security and data sovereignty have largely been addressed by the big three public cloud vendors: Amazon Web Service (AWS), Microsoft Azure and Google Cloud Platform, with only the most heavily regulated businesses lagging behind in terms of adoption.
This has fuelled a crowded IaaS market, worth a total of $31 billion in 2018, up from $23.6 billion in 2017 according to research firm Gartner’s latest figures.
