As you’re figuring out the best IT system for your growing company, you’ll come across three types of cloud options. These are public cloud computing, private cloud computing, and hybrid cloud computing. Let’s take a look at the definitions of each of these. Understanding each will help you decide what option best fits your situation.
What is a Public Cloud?
In a public cloud, many customers share hardware that is managed by a cloud provider. The cloud provider keeps up the servers and data center equipment. Your group accesses it using the Internet (through web access set up by the provider).
A public cloud provides all the cloud computing benefits we’ve discussed before. It lets your company get the newest, fastest hardware and platforms without having to invest in or update the physical hardware.
What you get: Use of hardware managed by the cloud provider. Your company does not purchase any cloud-related hardware. Multiple businesses using the cloud provider’s service share the infrastructure. Anyone in your company (not just your IT department) can plug into more data and memory when they need it, through the provider’s web access.
Pay model: You pay for the amount that you’re using. If you want more storage, add it and pay for it. If you decide to use less, you will pay less.
What the cloud provider manages: The physical hardware, including hard drives, backup drives, network cables, power supplies, etc. In a Platform-as-as-Service (PaaS) model, the cloud provider will also manage operating systems and other middle-software.
What is a Private Cloud?
Private cloud computing is a cloud system that sits isolated in a cloud provider’s datacenter or in your company’s datacenter. Hardware and equipment are dedicated to you, not shared with other businesses. What makes private cloud computing different from a traditional data center? A private cloud computing system lets everyone in your company get more data and storage when they need it, rather than relying on manual changes that need to be made by an IT department.
What you get: The flexibility and scalability of Infrastructure as a Service. Anyone can choose to use more data and memory, and try different platforms when they need. They just access your private cloud through the Web.
You also get added control over privacy and security. If you need to meet specific privacy regulations or you want increased control over access to your hardware, a private cloud may be the right choice.
Pay model: Your company buys and manages all the needed hardware or a specific agreement is made with a cloud provider.
What your IT department manages: Your IT department manages your hardware, but does not have to be involved with manually setting up added memory or new platforms. All of your employees will be able to do this on their own.
What is a Hybrid Cloud?
A hybrid cloud system uses elements of both a public cloud service and relies on a company’s legacy servers or private cloud system. For example, your company may run a public cloud service such as our Cloud Backup and Disaster Recovery offering while maintaining your servers in-house. You might choose this model to find the right blend of provider-managed services and privacy.
What you get: A smooth transition into embracing the cloud. Cloud solutions can be introduced on a gradual basis and proper planning can be done for older, legacy applications.
Pay model: You would start paying subscription fees on cloud offerings that you use. This means you can eliminate the maintenance costs required for servers that are replaced.
What your IT department manages: Your IT department still manages the systems that continue to exist. They will still be a crucial part to migrate the rest of your applications to the cloud.
The Hybrid Cloud is a safe next step for a company looking to get involved with utilizing cloud technologies.
