However , any business planning to invest in a public cloud service for the next few years needs to consider potential pitfalls before signing on the dotted line .
“ One of the benefits of any cloud option , whether this is public hyperscale or private , is that services can be scaled up or down according to business need . Businesses should consider how likely it is that they will need to scale ahead of time – hyperscale platforms tend to operate on a pay-peruse model .

So it ’ s worth taking the time to evaluate whether a public cloud offering really is best suited to business needs , or whether it would be more prudent to opt for a multi-cloud or hybrid strategy . Both these could include some use of public cloud , but the key thing is that they avoid tie-in to one provider and enable businesses to interconnect infrastructures to run workloads in the most efficient and costeffective ways possible ,” he says .
The future of IaaS Network ( NWaaS ) and Software services ( SaaS ) are variants of IaaS , which allows hyperscalers to build upon the cloud infrastructure to deliver further value to enterprise and consumers , alike , according to WWT ’ s Rhodes :
“ It ’ s this ability to evolve that underpins consensus forecasts that IaaS will continue to grow at its current 20 %+ CAGR . It ’ s likely that Telcos overcoming
