Cloud computing consists of three different types of
services:
· ·
Cloud
infrastructure as a service
- · Cloud platform as a service
- · Cloud software as a service
Infrastructure as a Service (IaaS): Customers use
processing, storage, networking, and other computing resources from cloud
service providers to run their information systems. The capability provided to the consumer is to
provision processing, storage, networks, and other fundamental computing
resources where the consumer is able to deploy and run arbitrary software,
which can include operating systems and applications.
For businesses the
greatest value of IaaS is through a concept known as cloud bursting. Cloud bursting is the process of off-loading task
to the cloud during the times when the most compute resources are needed. In order for businesses to take advantage of
the IaaS they must build and implement software that has the ability to
re-allocate processes to the infrastructure cloud. There are four important considerations to
building and implementing software that can manage such re-allocation
processes:
- Developing for a specific vendor's proprietary IaaS could prove to be a costly mistake if the vendor were to go out of business.
- The complexity of well-written resource allocation software is significant and generally requires top-notch developer resources that do not come cheap. You will save money by budgeting and researching first.
- What will you be sending off to be processed in the cloud? Sending data such as personal identities, financial information, and health care data put an organization's compliance at risk with U.S. Sarbanes-Oxley (SOX) Act, Payment Card Industry (PCI), or Health Insurance Portability and Accountability Act (HIPAA) regulations.
- Understand the dangers of shipping off processes that are critical to the day-to-day operation of the business.
List of some Cloud Computing IaaS providers:
- · Amazon Web Services: Offers a complete set of infrastructure and application services that enable you to run virtually everything in the cloud.
- · IBM: Enables speed and dexterity for the faster delivery of new offerings and services.
- · Openstack: Openstack is a cloud operating system that controls large pools of compute, storage and networking resources throughout a datacenter.
- · Bluelook: Infrastructure as a service company that specializes in Cloud Computing and disaster recovery.
- · GoGrid: Provides automated provisioning of infrastructure over the Internet.
