SIMILARITIES OF PRIVATE & PUBLIC CLOUD

 

Today, we will buttress on the main  instrument in cloud.

 VIRTUALIZATION : Before Virtualization there was nothing like cloud. Virtualization gave birth to cloud which makes cloud computing possible. The reason is because, the word virtual which means, you have the ability to make available particular resources to be consumable via the network through the API CALLS. It can either public or private network. 

It all started with private data centres/cloud. Public cloud did not exist before private cloud.  Organization took advantage of virtualization to have that flexibility when it comes to partitioning and allocating resources as needed and efficiently utilizing the resources they had on-ground with the USE OF  HYPERVISOR. Even though they're in the private cloud sector  they still manage all the different appliances within the physical data centre, they needed the physical F5 LOAD BALANCER , FIREWALLS etc. All these falls within the loop of expenses. 

For example: 

Another organization wants to host an application which probably will be lunched in Europe. You have to factor to set-up a data centre in the EU which comes with certain limitations like capital. This is when big organizations like GOOGLE, MICROSOFT leverage the virtualization to a network structure which is spread across the globe via the open INTERNET. And provide some security services to be able to secure their resources virtually by integrating different technology.This is how public cloud existed. 

You give people the opportunity to consume those same virtual resources via the internet not through the co-operate network. However, the fact that you can access through the internet does not mean its not secure thats where most companies are skeptical when it comes to that. Google cloud has developed a  robust technology which you can use to protect your environment and improve on your security posture as and make it even better as compare to someone that running the private data centres. 

Today, Government agencies are adopting cloud. Due to its security postures.
