Do you know that according to Gartner poll, Private Cloud project deployments are increasing significantly in 2013 and nearly 90% of customers are looking at Private Cloud implementation and are either in the planning or early deployment stages? Is your shop currently looking into Private Platform as a Service (PaaS) Cloud implementation? Have you looked into what zEnterprise has to offer in this space?
This article gives insight on Private Cloud Implementation on zEnterprise and can help you learn how your organization can benefit from implementing a Dev/Test private cloud using PaaS with Linux on System z and why WebSphere Application Server (WAS) may be a perfect fit for a Dev/Test Private Cloud.
Learn how your organization can cut IT costs by deploying “self-service” for developers, using Dev/Test Private Cloud.
This article goes over what Applications are a good fit for Dev/Test Private Cloud and the benefits of this implementation, such as :
• Reduce the number of Dev/Test WAS environments using dedicated resources
• Reduce hardware and software license costs
• Improve speed of upgrades
• Standardize procedures and software levels
• Let developers set up and use new environments in minutes instead of days or weeks
• Simplify WAS infrastructure management
Article also goes over the key differences in managing cloud infrastructure on distributed platforms vs. mainframes and shows how Linux on System z plays a critical role in creating PaaS clouds.
• Mainframes can scale vertically, while distributed servers can scale horizontally.
• Linux on System z has much higher densities of virtual machines per processor core compared to distributed servers.
• Cloud implementation on zEnterprise can dynamically allocate workloads to available pooled resources.
• Linux on System z leverages z/VM’s ability to virtualize CPUs and memory, as well as share those resources among many Linux guests. One IFL can run the equivalent of many distributed servers.
• Consolidation of Linux workloads on a single physical hardware server allows multiple Linux images to run on z/VM IFLs without affecting IBM software charges for existing System z general processors.
Creating private cloud to host dev/test environments can save your company money and increase efficiency. Start small, but think big; create a cloud strategy and roadmap that involves getting leadership buy in, building business cases and presenting them in stages within your organization, standardizing procedures and using a fit-for-purpose approach to select pilot applications.
