Public cloud service providers (think AWS, Google, Oracle, and Azure) provide on-demand computing services and infrastructure which are shared with other tenants.
The benefits of a public cloud model include unlimited scalability (up or down), the ability to pay as you go (PAYG) – and only for what you need, a lower entry cost to innovation and prototyping due to shared resources, and lower capital expenditure..
However, getting there, staying there, and thriving isn’t always as simple as it sounds.
Shifting from an on-premises, private or hybrid cloud infrastructure to public cloud requires careful planning, preparation, and ongoing monitoring, as well as specific (and often hard to find) cloud management expertise and skillsets.
Your public cloud environment needs to be constantly optimised to ensure you are tracking usage costs, minimising redundancy and waste, and taking advantage of discounts for running large workloads.
And like any environment, it needs to be backed up and disaster ready.
