With more than a decade of experience in virtualization and helping clients to create smart plans for migrating their technology, Convergence is prepared to assist any client looking into cloud computing to understand where their organization would benefit, what model to choose and to develop a migration plan.
The benefits of keeping all or some of an organization’s IT segments in a cloud, rather than maintained and hosted on-site, are plentiful.
Reduced Spending on Infrastructure:
While there is generally a subscription, or usage fee for utilizing a cloud, there is a minimal upfront cost associated with hardware, installation and maintenance, and upgrading systems is spread across all of the cloud “residents”.
Ease of Access:
As with virtualization, your workforce will have improved accessibility.
Because capabilities can by rapidly and elastically provisioned to scale to need, often automatically, provisioning now runs on a “just in time,” “just as much” and for “just as long” model.
With public, or shared private clouds, network resources are assigned dynamically, according to customer need. As one user requires more network bandwidth in the form of memory or virtual machines, for example, resources can be provisioned from any location.
Cloud systems automatically meter used to control and optimize resources (storage, compute, bandwidth, active user accounts, etc.) Because resource usage is tracked and monitored, organizations have access to their technology analytics, and are able to learn from their usage trends.
If you’ve read our discussion of data center and desktop virtualization, the jump to the cloud seems like an obvious one for some segments of some organizations. To understand cloud computing, it is important to make clear the two basic distinctions, Service Models and Deployment Models.
Service models refer to the type of resource the user is receiving from a provider. There are many, and organizations are free to choose which they will take advantage of. Some of the more frequently utilized are:
Infrastructure as a Service (IaaS)
This allows the user to acquire processing, storage, networks, and other fundamental computing resources. The user is not responsible for the underlying infrastructure, but does maintain control over the operating systems, storage, and the applications deployed from it. In many cases, the user enjoys limited control of some networking components where they may deploy and run operating systems and applications.
Software as a Service (SaaS)
This allows the user to utilize applications via the internet. Just as with virtualization, the applications are accessible from various client devices and the consumer is not responsible for the management of the underlying infrastructure (network, servers, operating systems, or storage) for the service being acquired. In some cases, the capabilities of the individual applications are customizable.
Platform as a Service (PaaS)
This allows the user to deploy consumer-created or acquired applications created using programming languages and tools supported by the provider onto the cloud infrastructure. Again, the user is not responsible for the network, servers, operating systems, or storage, but does maintain authority over the applications and the particular configuration of the environment, when relevant to the applications.
Convergence is capable of assisting clients in navigating which service models are most appropriate for their enterprise, and can assist in developing an iterative approach to migration, to ensure that there are no periods of time when an organization’s resources are unavailable.
