To address this, application developers are making a shift to an agile mode of operations, building, and killing off or scaling up apps on a weekly basis depending on how successful they are at addressing specific business needs in their test phases. This means IT, used to months-long deployment cycles, needs to up its game. The automation and simplicity brought by converged and hyper-converged infrastructure goes a long way to enabling this, depending on the type of application in question, as a lot of the manual process about allocating computer/storage/network resource to applications will have to be handled automatically.
Catalyst 3: I need infrastructure on which I can do small-scale test and dev work on before I scale-up: Related to #2 above, another key criteria for infrastructure upgrade is that it scales up nimbly. Converged Infrastructure investments don't all start out as fully built-out blocks with dozens of nodes and hundreds of terabytes of storage available; often projects begin with a humble 4U deployment, and, when an application completes its test phase, it can be switched into "production mode" on the same infrastructure. This allows it to scale up seamlessly as the IT team slots more nodes into the block. Not having to move an application between a "test and dev" environment to a "production" environment can shave weeks off application roll-out and make IT teams that much more able to fulfil the dynamic needs of the business.
Catalyst 4: I need to support a new type of application/service that requires particular scale: the most common example of this we see to date is the move to 'virtual desktop' infrastructure (VDI). One that delivers mobility and speed to enterprises working to meet the needs of the Information Generation, without sacrificing security. Now, the performance and scale requirements of VDI are so high that organisations can't stand to be losing time and resources to operational management, or it ceases to be cost-viable. Converged infrastructure, for many, is key to eliminating the overhead needed to make VDI not only viable, but extremely effective at supporting new models for employee productivity.
Catalyst 5: I need to reduce risk in my operational infrastructure by moving services into the cloud: Cloud computing, thanks to its multi-tenancy and scale, is increasingly touted as the choice when building out new infrastructure from a risk-mitigation perspective. Public cloud services, however, tend to introduce complexity around the control elements CIOs might need in determining service levels for new applications. For example, around high availability, back-up snapshots, archiving etc., not to mention data protection, which adds a layer of complexity and cost that can make it prohibitive to go down the public cloud route. Converged Infrastructure, including new elastic-cloud converged systems, can provide a pretty broad platform on which to build a hybrid cloud, giving CIOs complete control of the risk profile of any given application or data set.
