7 Questions About the Cloud


What is the “cloud”?

The most basic definition is that it’s making use of someone else’s computers. Essentially, users place their data and applications on compute and data storage hardware managed by a third party, which makes this information available to authorized users over the Internet.


Why use the cloud?

The main reason businesses use the cloud is the amount of flexibility the cloud offers. Here are a few scenarios:

  • A private cloud on your own hardware, hosted in your own data center. Virtualization technology reduces the risk of downtime by using multiple servers configured in a cluster. This technology enables applications to run on multiple servers – so if one physical machine fails, applications smoothly migrate to another server without interruption.

  • A third-party cloud provider. Putting your workload in the cloud avoids capital expenditures for hardware, software, support and maintenance, which can be expensive. Cloud providers allow you to purchase what you need, when you need it.

  • An on-demand model. There are occasions when users need additional compute, network or storage resources for a short-term project. Instead of purchasing more expensive hardware, outsourcing to a cloud provider that provides utility billing is a great way to get scalable resources without over-buying equipment.

  • An efficient form of data protection. Many organizations would like to have a secondary data center to protect them from all forms of disasters that could take their primary site off line – think power outages or weather related events like tornadoes or snow storms. But a physical, secondary back-up site requires the purchase of duplicate equipment plus the  cost of another data center. By using the resources of a cloud provider like One Cloud Services, users can have the benefits of a failover site for a low monthly cost and no up-front investment.

What is the difference between colocation and the cloud?

Let’s start with how colocation and cloud computing are similar.

  • The cloud is always accessed from a data center via the Internet. 

  • Some businesses build their own private cloud on their own hardware in a colocation facility.

  • Many cloud providers use third-party colocation facilities to house their infrastructure.

  • Some cloud providers operate their own data center and have more control over everything that protects customers’ assets and data.

  • All reliable providers will have power back-up systems, robust environmental systems and redundant Internet access.

  • The term cloud essentially refers to using advanced virtualization techniques that allow for faster provisioning of services, higher uptimes, and more efficient use of IT resources including software, storage and security.

If you are considering whether you should be a colocation user or a cloud user, you have many choices including:

  • Use colocation to build your own private cloud. A colocation facility can provide the basic requirements for high availability. You could use multiple colocation facilities if your business requires geographic diversity. If you want to control your hardware choices and features, your virtualization platform, and your operating environment, this might be the right choice for you. Leverage the colocation provider’s facility and their access to network services.

  • Consider an IaaS engagement for your own private cloud. IaaS stands for “Infrastructure as a Service” which is a form of cloud computing. The IaaS provider is responsible for all server, network and storage hardware. Depending upon the engagement, you may also purchase the virtualization platform licensing from the provider as well. You avoid any capital expense for the data center or for the IT hardware. You may have a choice in the type of hardware and/or virtualization tools used. You may also have access to the virtualization tools to manage yourself, or the provider may take that responsibility as well.

  • Use a public cloud provider. There are public cloud providers who will provide you with access to their cloud platform in increments as small as an hour. You essentially pay for the time you use their assets which can include processing time, various types of software, storage and network access. In most cases, you use whatever hardware the provider uses with little or no choice. And in many cases, you may be using shared resources with other customers of all shapes, types and sizes. We work with customers who are both using our colocation services to create their own private cloud, and others who rely on us to build and manage a cloud environment for them.

Is colocation a better option than the cloud?

Colocation and the cloud are not mutually exclusive.

The key decision factors are the amount of investment and control that a business wants to exercise over its hardware and infrastructure, how comfortable the IT staff is with cloud computing, and how well suited the business is for a cloud environment.

Some businesses that are using the cloud as a colocation user are very particular about the hardware platforms that they use, and have IT staffs that are well versed in server virtualization, network storage, and cloud environments. They want total control over the hardware being used since they have an affinity to certain hardware vendors, or are comfortable with the feature set the vendor provides.

Other businesses are more comfortable running hardware servers instead of a cloud solution: perhaps the applications being used are not easily migrated or maybe they are using hardware and systems that cannot be virtualized. While these colocation users are more traditional in their approach, they can always introduce a cloud solution for a portion of their environment.

Businesses looking solely at cloud providers may be trying to avoid upfront hardware costs by simply paying as they go through monthly fees, and are comfortable relinquishing the hardware and operating system choices to the provider.


Is the cloud replacing the colocation industry?

The short answer is no. Although cloud services have taken business from colocation providers, there is nothing to indicate that the colocation industry is dying out. Cloud services and platforms require physical infrastructure to serve as their backbone: even as more businesses move to the cloud, there will still need to be physical servers, and the most efficient place to house them is almost always a colocation facility.

That said, the colocation industry does need to change if providers don’t wish to begin suffering significant losses. As noted by Data Center Knowledge’s Keao Caindec, providers need to start offering easy direct connect, online ordering, commitment-free contracts, and better customer service – all things offered, incidentally, at Liberty Center One.

That said, if your servers aren’t properly cooled or the colocation facility operates at a temperature higher than 80 degrees, you may have a problem – excessive heat can irreparably damage many core components of a server.


How does security compare for colocation compared with cloud services?

Strictly speaking, it doesn’t. Cloud computing, since it’s entirely digital, necessitates a greater focus on protecting data in-transit, controlling access, and providing a means of secure connectivity. At the same time, these are all security considerations that are likely to come up if you colocate, as well – especially if your business employs remote workers or outsources its labor.

In addition, while colocation requires servers to be physically secured, this is almost always handled by the host – the client very rarely has to participate in protecting their physical servers.


Don’t I give up control by going to the cloud?

The opposite is true. Because the cloud is much more flexible than a static, on premise server, users can decide how much compute and storage resources they need to use and when. Cloud users have complete control over how much they use and can scale up and scale down on demand.
