A Cloud Computing Glossary
If you are new to cloud computing or are beginning to move an IT network to a private or public cloud, here is a top list of terms that you should know while researching cloud solutions.
Platform as a Service (PaaS) – PaaS is simply delivering Operating Systems (OS) to desktops as a service via the Internet.
Infrastructure as a Service (IAAS) – IAAS allows you to spin up additional machines in the cloud depending on your local networks bottleneck. For example, if your Active Directory (AD) servers get hit hard at a certain time of day, you can spin up additional domain controllers in the cloud to help alleviate the issue.
Software as a Service (SaaS) – SaaS enables you to connect to services via an Internet browser or application portal for a monthly service fee.
Elasticity – Elastic means that you can expand your storage on demand. For example, you have a web site that uses 5 servers all year long for online purchases. During Christmas, demand increases and you automatically spin-up 2 additional web servers to handle the demand. When demand dies, the servers deprecate. This is elasticity.
Amazon Elastic Compute Cloud (EC2) – This is Amazon’s cloud offering that allows you to purchase computer resources in the cloud to build scaleable web applications.
Windows Azure – Windows Azure is Microsoft’s Cloud solution for building scaleable applications in the cloud.
iCloud – iCloud is Apple’s offering that allows you to story your music, photographs, documents, apps in the cloud for backup purposes; you will never lose a thing. Furthermore, Apple allows you to synchronize or push this information to all of your apple devices such as iPad, iPhone, and iTouch.
Google Apps – Google has an entire office suite available in the cloud. Examples include, Gmail, Google docs, Google drive, calendaring and spreadsheets.
Dropbox – Dropbox is a SaaS solution that backs up and synchronizes your data to all computers that have the software installed. 2 GB is a free account and you can purchase additional space up to 100 GB.
Hybrid Cloud – A hybrid cloud is how many companies begin their move to the cloud. You have a local network and a private/public cloud. For example, your company may have a Storage Area Network (SAN) but also leases space from Amazon at peak periods.
Amazon S3 – This is simply an Amazon cloud storage service. If you need storage, you can purchase space from Amazon for a monthly fee.
Cloud OS – A cloud OS is an operating system that is only available when connected to the Internet. A cloud OS may also have an offline mode. A good example of a cloud OS is the following: Google Chrome OS and Jolicloud.
Cloud Provider – Microsoft, Skytap and Vmware are all cloud providers. They all hope to get your business in the cloud.
