Infrastructure as a Service

Learn what Infrastructure as a Service (IaaS) is, and how you might benefit from using IaaS with IBM® Integration Bus.

Infrastructure as a Service acts as the equivalent to computing hardware by using virtual machines. An IaaS configuration reduces the cost overhead of managing many servers, whether on premises or off premises, as you do not need to manually configure each system. For example, you can apply security patches to all virtual machines simultaneously by using a script.

The advantage of using IaaS with IBM Integration Bus is to create a scalable solution that does not require increasing configuration as it grows in size. By configuring scripts, you can scale and change attributes as required, instead of manually recoding the system infrastructure.

You can use IaaS on premises or off premises, but the primary benefit of IaaS is the ability to use a vendor to reduce the costs of maintaining and configuring the physical machines. If you want to use IaaS on premises, consider the skill availability of system architects in your organization to configure your architecture, and the associated costs.

The benefits of using an IaaS configuration are:

Considerations for using IaaS are:

For an example of an IaaS-based IBM Integration Bus solution, review the following business context:

A retail company uses an IBM Integration Bus solution that uses the IBM Retail Pack for its transaction system. The company knows that its peak message processing period is December. Their previous solution used their own on-premises servers, which met the peak demand. However, during the rest of the year, the full capacity of the servers was not used, but the company still had to pay the associating operating and maintenance costs for the entire year.

The retail company changes its infrastructure to an IaaS solution. The retail company now pays an IaaS provider for public cloud servers. The retail company pays the IaaS vendor monthly, by capacity required. The company pays for more IaaS capacity for December only to meet its peak demands. As the company now use less resources across most of the year, this solution is a cheaper option.

Graph explained by following text.

The graph shows how a static solution remains the same cost throughout one year, but the IaaS solution cost is consistently lower, except during peak usage. The result is that the retail company has capacity that it requires during its peak period, but does not continue to pay for that extra capacity for the rest of the year.
