Today's choices are much more complex. Organizations can choose to deploy to public, private or hybrid clouds through an on premises, fully hosted or colocated data center – or some combination of them all. The drivers that lead organizations to choose the best model are evaluated on a case-by-case basis, while keeping in mind the overall business strategy. Security concerns and cost concerns often top the list, but consideration for how to manage the application workloads effectively should not be overlooked.
Fit the Environment to the Workload
As Gartner points out, the public cloud isn't always the right choice for application deployments. Factors such as location, agility and modern vs. legacy applications all play into the final decision. Different applications will have different workload requirements which play a part in the overall deployment decision. The environment chosen must satisfy load and performance requirements, along with any compliance and data security mandates. Your applications may also have a requirement for low latency or to rapidly scale in and out to handle spikes in demand.
Few if any organizations will completely migrate to a pure public cloud scenario. What is more likely is that you will have a mix of environments to suit your variety of needs. It’s wise to choose the cloud environment that is the best fit for your organization now, making sure that you have thought through integration and migration issues while remaining agile to changes and future growth requirements.
- On Premises
On-premise deployments provide a controlled environment for the security of your most sensitive data, but a requirement to quickly scale demand would add extra hardware and bandwidth expenditures. Redundancy is also required to satisfy failover and disaster recovery needs furthering the upfront cash outlay. This potentially unused hardware to anticipate the “just in case” scenarios and the costs to administer the applications and manage the hardware can be cost prohibitive causing organizations to sacrifice their data security.
Hosting is appropriate for relatively small workloads that don't require scalability and can run in a low-cost, commodity hardware environment.
- Public Cloud
Public cloud providers are great at meeting scalability requirements while you only pay for what you need when you need it. The downside to this is that it is a standard offering, and that it often times doesn’t offer the flexibility to adapt to special circumstances that deviate from the norm. Applications that require highly-elastic capacity are most appropriate for this environment.
- Private Cloud
By industry analysts IDC’s definition, “private cloud services are shared within a single enterprise or an extended enterprise, with restrictions on access and level of resource dedication, and are defined/controlled by the enterprise, featuring a level of control beyond what is available in public cloud offerings. Private clouds can be onsite or offsite and can be managed by a third party or by in-house staff.” Private cloud offers on-demand scalability with dedicated hardware allowing an enterprise to take advantage of the cloud, yet maintain a high level of security.
- Hybrid Cloud
A hybrid cloud allows organizations to operate in a mixed deployment architecture. Applications can be matched to the environment best suited for their needs, and workloads can move between environments depending on business concerns such as testing and disaster recovery requirements. Hybrid cloud is well suited for organizations to use the public cloud for applications that experience spikes in demand and a private cloud for those applications that have mandates for either security or compliance.
Colocation is ideal for organizations who need a single tenant structure but would like to take advantage of the cost economies of off-site hosting by reducing capital expenditures. Colocation provides all the benefits of hosted environments while allowing organizations to meet disaster recovery, security and compliance demands.
