The private cloud is sometimes confused, either accidentally or intentionally by vendors, with the evolution of internal IT systems, and as such its benefits often get overlooked when compared to the public cloud. Still, organizations have much to gain from running some of their applications through dedicated private cloud resources for better control and cost management, while continuing to use a public cloud as needed.
Why Some Applications are Best Run on Private Cloud Infrastructure
There isn't a one-size-fits-all solution for running applications efficiently. Performance and bandwidth requirements, as well as workload complexity, vary from one piece of software to the next, and IT departments must be equipped with flexible solutions to handle all of the various use cases. While it makes sense for many organizations to run entirely on public cloud resources, one of the most logical use cases for a private cloud is app development and testing. A private cloud makes dev/test more cost effective by leveraging an organization's on-premises compute, storage, and networking assets. With fixed-cost capital expenditures on hardware, developers can code and QA software as much as they want without fear of "running up the meter".
Further, with a private cloud that is compatible with the leading public cloud provider Amazon Web Services, organizations can deploy an end-to-end solution that provides the best of both worlds: less expensive development and testing with private cloud resources and near-infinite scalability for production apps with the public cloud. Since Eucalyptus is the only vendor that can transform an organization's IT infrastructure into a private cloud that behaves just like Amazon Web Services (AWS), the combined hybrid cloud becomes the perfect solution that marries convenience and control and satisfies both developers and IT operations.
"In addition to using Eucalyptus for our development, test and staging environments, we've found it easy to quickly provision on-site distributed compute resources to solve customers' unique spatial problems," stated Mosaik Solutions vice president Chip Strange. "This is an extremely valuable capability that allows us to provide assistance to our customers in a timely manner."
Continuous Integration with Private Cloud
Given the rapid adoption of DevOps and Continuous Integration, automatically testing all parts of code is a key workflow for many teams. Letting a bug slip through the cracks to production can be costly, but leveraging the public cloud entirely for non-revenue generating activities such as QA can create ever increasing operational expenses.
"The ability to ship, get feedback from your customers and iterate on your product quickly is a major competitive advantage," wrote Florian Motlik for the Treehouse Blog. "Especially when building the first iterations of your product the importance of shipping quickly and regularly can't be overstated."
To attain such an advantage, organizations can enable Continuous Integration on a private cloud, where they benefit from dedicated performance and fixed costs. Eucalyptus enables such a setup while also providing the ability to seamlessly deploy software unchanged to AWS.
Developers can go on using familiar features such EC2, EBS and S3, AWS tools for image management and monitoring, plus automation utilities such as Chef to streamline workflows and boost efficiency. The combination of AWS and Eucalyptus leads to more economical and effective DevOps operations.
