There are 5 Steps for Building a Cloud Computing Infrastructure:
Step 1: First you should decide which technology will be the basis for your on-demand application infrastructure.
The decision related to which virtualization technology will be the organizational standard is already made. But decide before you start if it has not made. There are cons and pros to both a homogenous and heterogeneous virtualization infrastructure and the decision will impact the ability to monitor and manage infrastructure later. So make this decision first.
Step 2: Determine what delivery infrastructure you will used to abstract the application infrastructure.
Cloud infrastructure’s the on-demand capabilities are first designed to do two things: make efficient use of resources and ensure scalability. Some method of load balancing/application delivery will be necessary to accomplish the former.
To abstract the applications, this layer of the architecture will helpful and will provide a consistent means of access to users, shielding them from the high rate of change which occurs in the infrastructure.
The delivery infrastructure or load balancer will need to be included in the provisioning process and to provide visibility into application capacity, performance as well as resource management.
Many solutions are there to match you choice, but select one solution in which you will integrate the system into the architecture. Also you need to verify the solution that whether it is capable of providing the visibility you will need into performance metrics or not. So, decide what metrics and thresholds you’ll use to trigger provisioning processes and ensure that the infrastructure can support it.
Step 3: Prepare the network infrastructure.
Prepare the network to deal with an on-demand application infrastructure. Application delivery: must be configured correctly for the application being deployed, Hardware: network, storage. The network must be configured to deal with such change without requiring human intervention and must be able to handle applications which migrate from hardware to hardware. For this, the network will require constant optimization to adapt to changing traffic patterns.
Step 4: Provide visibility and automation of management tasks.
Remember, visibility is a key to an on-demand infrastructure. An associated management systems and the infrastructure must know what is running, when and where to evaluate available resources. Find how you will collect the data and from where. Decide which system is authoritative for each metric and verify to feed that information in real-time to the automation system.
Step 5: Integrate all the moving parts, such that the infrastructure and realizes the benefits of automation, abstraction and resource sharing.
The last one is most difficult part, and requires the previous steps be completed. The integration, automation of all the pieces of the infrastructure like storage, network, and application enables the infrastructure to act on-demand. The realization of cost-reduction benefits will be marginalized without automation.
The integration step automates workflow. Automation requires constant monitoring across the application infrastructure from the network layer to the applications executing in the environment.
In many cases this integration may require a custom solution. if you are an early adopter it may be necessary to build management system and an automation framework yourself.
Toward a cloud infrastructure, Virtualization is the first step. It is important to re-evaluate the suitability of each critical layer of the architecture for inclusion in the new infrastructure model.
An investment will require for Building cloud infrastructure, if not in solutions or hardware then in time and effort. Automation, Reconfiguration and Integration will require significant IT resources to accomplish.
Now, we are sure that you are able to build a cloud infrastructure by following all these Steps.
