Whether a public, hybrid, virtual private or private cloud, everyone agrees that cloud computing has key benefits include scalability, instant provisioning, virtualized resources and ability to expand the server base quickly.

The majority of public cloud deployments are generally used for quality assurance testing, application migration/development testing or tech startups but not limited to, or where user demand peaks and falls at certain times of the day, month or year. Private cloud computing, by definition, is a single-tenant environment where Compute, Storage, and Network are dedicated to the sole organization business needs, deployed and maintained in private or colocation data centers space.

IZA Technologies, understanding security and compliance requirements being the business fundamental requirement, offers Support Services to both public and private cloud computing, when public cloud resources are integrated with private or virtual private cloud services creating a unique secured hybrid environment.

Private Cloud Services:

Private cloud hosting by definition is a single-tenant environment where the hardware, storage, and network are dedicated to a single client or company. A more common type of private cloud computing solution is virtual private cloud hosting, a multi-tenant environment where companies achieve networking isolation while keeping costs down by buying hardware slices with other tenants and creating private subnets. A private cloud hosting solution, also known as an internal or enterprise cloud, resides on the company’s intranet or hosted data center where all of your data is protected behind a firewall. This can be a great option for companies who already have expensive data centers because they can use their current infrastructure

Private cloud computing also has a number of benefits:

• Hybrid Deployments – If a dedicated server is required to run a high-speed database application, that hardware can be integrated into a private cloud, in effect, hybridizing the solution between virtual servers and dedicated servers.
• Customizable – Hardware performance, network performance, and storage performance can be specified and customized in the private cloud.
• Security – Because private clouds are dedicated to a single organization, the hardware, data storage and network can be designed to assure high levels of security that cannot be accessed by other clients in the same data center.
• Compliance – SOX , PCI and HIPAA compliance can be delivered through a virtual private cloud or fully private cloud deployment, because the necessary hardware, data storage, and network configurations are dedicated to a single client.

As opposed to public clouds, fully private clouds are not delivered through a utility model or pay-as-you-go basis because the hardware is dedicated. However, IZA Technologies offer the same pay-as-you-go model as public clouds, with the added bonus of specifically provisioned hardware, network and storage configurations. Private clouds, including Virtual Private Clouds, are generally preferred by mid and large size enterprises because they meet the security and compliance requirements of these larger organizations and their customers.

Public Cloud Services

The main differentiator between public and private clouds is that you aren’t responsible for any of the management of a public cloud hosting solution. Your data is stored in the provider’s data center and the provider is responsible for the management and maintenance of the data center. This type of cloud environment is appealing to many companies because it reduces lead times in testing and deploying new products.

Public Clouds have a number of benefits:

• Utility Model – Public clouds typically deliver a pay-as-you-go model, where you pay by the hour for the compute resources you use. This is an economical way to go if you’re spinning up and tearing down development servers on a regular basis.
• No Contracts – Along with the utility model, you’re only paying by the hour – if you want to shut down your server after only 2 hours of use, there is no contract requiring your ongoing use of the server.
• Shared Hardware -Because the public cloud is by definition a multi-tenant environment, your server shares the same hardware, storage and network devices as the other tenants in the cloud.
• Self-Managed –With the pay-as-you-go utility model, self-managed systems are required for this business model to make sense. There is an advantage here for the technical buyers that like to set up and manage the details of their servers, but a disadvantage for those that want a fully managed solution.
