Now, we can answer the questions:
Why is public cloud best for business?
1. The public cloud providers have a better idea of security than the business owners/single IT person, etc.
2. Public cloud providers build security in to their services (they have the uber clever guys that build it in – businesses don’t!)and their policies are.
3. Public cloud therefore can enforce better security than most businesses operate (e.g. passwords must be changed every x days) A business may not think.
4. Most businesses don’t need bespoke set up of servers. Public cloud offerings like Office 365 and Azure have enough flexibility for businesses to do exactly what they were building before.
Accessibility and simplicity: Public clouds are easy to use
One of the major strengths of a public cloud model is that it is easy to access and use. It also allows for the option of working from home or while travelling for business, whereas most private cloud models are limited in this respect and addition infrastructure and security needs to be added to enable you to do this.
Accessibility and simplicity is its number one advantage, as well as generally fast speed. Hybrid clouds are much more complex because you need to manage private and public data centres together.
Big market and variety of providers: Find the provider that match your needs
There is a growing market for cloud computing services and the offer is growing as well. This means providers have to keep their offers competitive and you can shop around choosing from a wide variety of providers.
If one platform doesn’t match your needs, you can move on to a different one with little fuss thanks to subscription models, while private clouds doesn’t offer any adaptability meaning you have to invest and commit upfront.
High scalability: with public clouds changes are handled easily
Since public cloud services are demand based, they have virtually unlimited scalability, meaning any changes in size or volume of your company’s needs will be handled easily. Any rescaling and changes in activity will be met automatically.
There is a vast network of servers available to distribute the load to if your needs increase, and this simply could not be done in the case of private cloud model without adding new infrastructure.
Cost effective: with public clouds you pay what you use
Public clouds operate on subscription models, meaning that you literally only pay for what you use. With some, you can pay less or nothing if there is no traffic. You can easily add and drop your capacity and the costs will mirror that.
Apart from that, you don’t need to invest in infrastructure, maintenance, software and regular updates which would be a must in the case of private and hybrid cloud models. You would have to provide facilities, up-to-date equipment and hire IT professionals to run and maintain your private cloud computing on-site.
Time efficient: Setting up takes only a few hours (or minutes)
As we have mentioned, setting up an in-house server or private cloud solution is both costly and time consuming. On the other hand, public clouds are readily available and setting up systems and configuring platforms takes only a few hours or even a few minutes.
