Most organisations are moving towards the public cloud because of four main reasons. It is important to understand how each of these factors works for the organisation to move out from the hosted on-premises/private cloud and move towards cloud-native solution development.
1. Economy at Scale
More significant economies of scale: No private cloud can compete with Microsoft, Google, and Amazon on price. And the public cloud providers are constantly buying boatloads of the latest security technology.
2. Low capital investment
Converting capital expenditure into operational cost
Shifts capital expenses to operational expenses: Its pays as you go, versus building an entire data centre, no matter how virtualized it may be. Once you stabilize your utilization reserved model brings organisations, even more, cost benefits.
Better utilization rates: With the private cloud, organisations still have to build and maintain all kinds of servers to meet spikes in demand across various divisions or functions. The public cloud offers the same spare demand on a pay-as-you-need-it basis model. In that sense, you have to invest in efforts like patch updates to keep your environment up to date and in compliance.
Keep infrastructure costs low for new projects: With private clouds, you still need to scare up sometimes scarce on-site resources for unplanned projects that may pop up.
3. Low technology debt
Expedite the innovation process through quick integration with the latest technologies
Private clouds tend to use older technology than public clouds: Organisations may have spent hundreds of thousands of pounds on new hardware and software, but try getting your organization to agree to that every year.
Public clouds offer greater elasticity: ” Organisations never consume all the capacity of a public cloud, but your private cloud is another matter entirely.”
4. High Security with Low maintenance cost
Cloud provider will take care of most of the critical services like compliances, security, scalability, and availability
Public clouds are hardened through continual hacking attempts: Thousands of hackers have been pounding Azure, Google and Amazon for years now. The public cloud providers are ready for anything at this point.
Public clouds attract the best security people available: They seek out the top security experts, will pay them top pounds, and treat them as the most important part of their businesses, which they are. Do traditional enterprises treat security teams this way?
Private cloud staff competence is unknown: Your organization may have a lot of talented and knowledgeable people, but is data security the main line of your business?
Private cloud penetration testing is insufficient: Even if you test your applications and networks regularly (which man organizations don’t), these only tell you if things are secure at that exact moment.
