Cloud-computing providers are classified according to the service layers or delivery models that are offered. The range extends from the basic infrastructure services to the platform and application services. The National Institute of Standards and Technology (NIST) defined the service layers and agreed on the following three service models:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS
- Software as a Service (SaaS)
Through an integrated system of hardware and software, IBM® PureApplication™ System provides a single interface to control the platform and infrastructure elements. This interface adds further value to the software patterns concept by managing all of the underlying hardware infrastructure components when deploying applications in a private cloud environment. PureApplication System is also a consolidation platform with the capacity to support multiple Platform as a Service (PaaS) instances that host various enterprise applications. This IBM Redbooks® Solution Guide describes the PureApplication System and its capacity to support PaaS. When using the PaaS model in a PureApplication System, the objective is to supply the necessary components for rapidly building and deploying applications in the cloud, as shown in Figure 1.

Did you know?
IBM PureApplication System is pre-optimized for IBM application patterns that ship with the system. More than 200 patterns that are optimized by independent software vendors (ISVs) and IBM Business Partners are also available online through the IBM PureSystems™ Centre at http://www.ibm.com/PureSystems/Centre, which is a repository of products that are built for the PureSystems family.
IBM PureApplication System implements the PaaS layer to provide superior IT economies when operating in traditional or private cloud environments. With the PureApplication System, customers can create their own patterns of software, middleware, and virtual resources. Customers can provide and share these patterns within a unique framework that is shaped by IT guidelines, preferred practices, and industry standards.
These practices have been gathered from many years of IBM experience with thousands of clients around the world and are infused throughout the system. IBM PureApplication System provides the following advantages:
- Agility: By automating key processes such as operating system installation, middleware configuration, and application deployment, PureApplication System can reduce the cost and time that is required to manage the platform.
- Efficiency: With PureApplication built-in expertise, customers can optimize critical business processes and conserve valuable resources to get the most from the systems in terms of energy efficiency, maintenance, and fast response to problems.
- Simplicity: PureApplication built-in patterns of expertise can help customers easily consolidate different servers, storage, and applications into an easy-to-manage, integrated system that can be controlled from a single management console.
- Scalability: By defining a high-level set of parameters and policies, administrators can use PureApplication System features to scale the application up and down automatically according to the workload.
- Reliability: IBM PureApplication System provides a more reliable platform for your applications by automating the manual processes that are identified as causes of failure or problems.
Figure 2 shows the value from IBM PureSystems offerings.

When you consider migrating or creating an application, it is important to understand why you need to put your application in a cloud infrastructure that is provided by the IBM PureApplication System. One reason is to support fast business response and dynamic workload demands by using the cloud capabilities of the system. You can enable cloud service providers to serve your application as a PaaS by using infrastructure, platform, and application patterns in a fast deployment configuration with provisioning.
Whenever possible, use the optimization and convenience of a virtual application pattern, as it always provides the lowest total cost of ownership (TCO) and shortest time to value. However, there are scenarios where you require detailed configurations and decide to use the elaborated control that is available with virtual system patterns.
Patterns simplify and automate tasks across the lifecycle of the application. Customers and Business Partners are seeing significant reductions in cost and time across the application lifecycle with the deployment of a PureApplication System. Here are some of the benefits of deploying a PureApplication System:
- Adjusting to rapid changes, such as application usage spikes, in near real time
- Identifying problems faster and deploying solutions quickly
- Reducing maintenance time and cost
Figure 3 shows the advantages of using the IBM PureApplication System solution.
Figure 3. Value delivered
IBM PureApplication System architecture is based on three principles:
- Built-in expertise: Capture and automate what experts do where infrastructure and application expertise enhance application time to value.
- Integration by design: Deeply integrate and tune hardware and software.
- Simplified experience: Make every part of the IT lifecycle easier by using an integrated management and an open solution ecosystem to broaden choices.
IBM PureSystems are built including patterns of expertise. Patterns of expertise accelerate the time to value of applications, services, and business processes by encapsulating guidelines and preferred practices into a repeatable and deployable form. They can automatically configure, manage, and optimize the elements of a solution, from the infrastructure resources up through the middleware and applications. Basically, they are categorized in three types, one for each service layer:
- Infrastructure patterns, which are used in IaaS
- Platform patterns, which are used in PaaS
- Application patterns, which are used in SaaS
Figure 4 shows the relationship between the patterns and IBM PureSystems products.
Figure 4. Patterns of expertise and IBM PureSystems products
Organizations can use the IBM PureApplication System to rapidly deliver an application-aware cloud with expert application patterns to users to achieve quick time to value and reduce cost and risk. Expert application patterns that are offered by IBM and IBM Business Partners are the basis for PaaS and SaaS, and dramatically reduce the effort and expense that are required for deploying and maintaining a private cloud.
For example, organizations can use the IBM Business Intelligence Pattern on the IBM PureApplication System to deploy business intelligence (BI) applications in an optimized, fault-tolerant environment in minutes. Created for the deployment of IBM Cognos ® BI software, the pattern reduces the time, effort, and cost of building and deploying an enterprise-grade, proven BI solution.
Integrated support for resource contention is automated to help ensure the performance of the most critical applications. A company can port hundreds of applications to the cloud and rely on the IBM PureApplication System to track and manage all of the shared resources. Automated data governance policies help reduce compliance risk.
Organizations using IBM PureApplication System for Web Application Server applications benefit from the removal of manual steps and automated delivery for fast time to value and increased agility in responding to business opportunities. Costs and resource requirements are reduced with the pre-integrated and optimized environment, and the patterns that are built into the system reduce the amount of in-house expertise that is needed. The system also enables applications to be implemented in a repeatable, optimized way that lowers the risk of human error. Real-world experiences show how the value adds up.
With IBM PureApplication System:
- Pre-integration and rapid implementation meet demanding timelines.
- The system successfully meets the extreme peaks and troughs inherent in analytics workloads.
- Costs are reduced across the development and operations lifecycle.
Figure 5 shows the value that is delivered through use case examples.
