A long heritage for hybrid cloud
“The biggest system stored internally was a platform for production and video editing that required storage capacity and bandwidth, with editing workstations connected via fiber,” says t -he. “As in any case the customer required to keep servers and storage systems, we hosted a few additional servers to store files and network services with replication to the cloud” external “for backup purposes.”
The hybrid approach is also ideal for launching, according to Chris Poelker, vice president, enterprise solutions for FalconStor Software and author of Storage Area Networks for Dummies (specialized storage networking for dummies) .
“Instead of a radical change, a hybrid approach allows us to get used to the concepts and contracts, while leaving us control over all data and key applications,” he says.
It may be that there is such a sense of ownership which says among policymakers, while large companies inform about the capabilities of cloud computing. As we recently reported in our study on the opposition between private cloud and public cloud , there is a duality between ownership and leasing; Some IT managers do not consider that a computing platform is up to them if it is not under their roof … figuratively, of course.
It is also possible that you run critical legacy systems that do not support the migration. As says Erez Yarkoni Telstra, the primary motivation for customers to opt for hybrid environments holds the applications and processes that simply can not reside in most cloud computing systems.
“They have not been designed and have not been written to reside there, which is why they are not made for these systems,” he deduced. “When these customers want to benefit from a type of supply to demand, they use a private cloud offering in order to run it themselves.”
Combining the opportunity to achieve greater use of technological resources on site and the flexibility to exploit the advantages of the public cloud in terms of cost and agility, cloud computing will become unavoidable hybrid to reach the next level of technological services business.
Chris Poelker shares the same opinion and adds that, so far, the simplest applications to migrate to the public cloud are those generally available “ready to use” from multiple vendors, such as electronic mail, sales support, CRM and back office finance.
In some cases, the choice to adopt a hybrid cloud strategy is a decision of the supplier or integrator third cloud systems. Greg Archbald, CEO of specialist data management relating to oil and gas GreaseBook, saw a multitude of users adopt much more than they can handle.
“If a project is not managed properly or if the company does not have the expertise to manage their private or hybrid cloud, the extent of the support needed by some large customers can weaken the provider,” said Greg Archbald.
Finally, a hybrid environment can be a simple question of redundancy. Imagine that you run two copies of the same data, one private and one public, each performing the same workload. For a minimal cost, you have a ready-clone of the company in an environment as a backup the active copy in the other.
When you are in the middle of a stable workflow, you can run your copy of the private cloud and save costs of payment to use the public cloud. If there is an increase in traffic that requires a rapid increase in capacity, you can intervene and activate the copy of the public cloud to absorb the flexibility required by the workload. Or, in the words of Esmerelda Swartz, billing provider MetraTech Marketing Director: “The hybrid approach also provides significant protection against confinement supplier vis-à-vis.”
Seattle Bank uses the hybrid cloud precisely for this protection. Using a third-party extension module for VMware vCenter, the data stored in the public cloud environment company AWS are fully integrated and constantly communicate with the private cloud on site.
Snapshots are taken every 15 minutes, which means that if there is a problem with the virtual machines on site, those are integrated on AWS to restore service. As stated Scott McGillivray, Vice President and Chief Information: “We wanted to expand our infrastructure for disaster recovery and business continuity public cloud providers without requiring the proposed new center for treatment..”
