Many of you heard IT people talking about different types of cloud computing, where different services are being provided for you, but you don’t vague about them. So in this post, we’ll tell you detailedly how many types of the cloud computing and the diference between them.
Types of cloud computing
Cloud computing comes in three forms: private clouds, public clouds, and hybrids clouds. Depending on the type of data you want to work with, here’s the different levels of security and management required among them.
Private clouds are data center architectures, which are owned by a private company providing many solutions such as: provisioning, scalability, flexibility, automation and monitoring. Not aiming at selling as-a-service offers to external customers, the private clouds gain the benefits of cloud architecture without having to give up the control of your own data center.
Private clouds is usually expensive, so this is not a good choice for the Small-to-Medium sized companies, they are typically used by large enterprises. Private clouds are keeping assets within the firewall.
A public cloud can simply be considered as the internet. Service providers use the internet to create resources like applications and storage, which are available to the public, usually called ‘public cloud’. Amazon Elastic Compute Cloud (EC2), Google AppEngine, IBM’s Blue Cloud, Windows Azure Services Platform… etc are some typical examples of the public cloud.
In case you are a user, the public clouds will provide the best economies of scale, which are inexpensive to set-up as everything such as hardware, application, and bandwidth costs has already covered by the large provider.
However, the cloud publics still exists some limitations, as it’s not suitable for every organization. It’s limited the configuration, security, and SLA specificity, which makes it less ideal for services using sensitive data.
When choosing a Hybrid clouds, you can maintain control of an internally private cloud while still relying on the public cloud, as you need. For example, portions of applications can be transferred from the Private Cloud to the Public Cloud. This will have many benefits during predictable outages such as scheduling maintenance windows, rolling brown/blackouts.
Cloud based on Disaster Recovery (DR)/Business Continuity (BC) services will allow companies to contract to a Managed Services Provider that quickly specializes in getting business back online.
