Week 4 - Types of Cloud Deployment Models

There are four common types of cloud deployment models: Private, Public, Hybrid, and Community. When a business sets out to implement cloud computing, they will need to determine which deployment model best meets their needs. The deployment model is basically the location of the cloud.

Private cloud deployment is an internal cloud. The business owns and manages the infrastructure for the cloud. The cloud is accessed thru a private network and only for the use of the company - it isn't shared. The main reason companies keep a private cloud is for security. This cloud is behind their firewall. Organizations that have to comply with regulatory standards that regulate privacy and audits will use a private cloud.

Public cloud deployment is owned and hosted by a cloud provider at their location. Services and infrastructure are provided to a business. This deployment works well with companies that have spikes in their usage during peak times of the business. The cloud provider is able to increase and decrease the size of the infrastructure based on the needs of the business.

Hybrid cloud deployment is a combination of private and public cloud deployment. Businesses will keep secured applications and data on a private cloud. They will have the shared application on the public cloud. This still gives them cost benefits. This also allows for cloud bursting. Cloud bursting allows a private cloud to burst into the public cloud when load spikes need the extra capacity.

Community cloud deployment is a setup where businesses with the same setup is needed, shares the cloud with other businesses. If a business is working on a joint venture with another company, they may setup a cloud to share the information.

This chart from CloudTweaks (2012) shows the size of businesses and what cloud deployment they tend to use.

Week 3 - Three types of cloud services

In Cloud Computing, there are three types of common cloud services and four types of common cloud deployments. This week, we will talk about the three types of services. They are software, platform, and infrastructure services.

Software as a Service (SaaS) allows businesses and consumers to use applications that are hosted by a cloud provider. When you use Netflix, Microsoft 365, Gmail, or Google docs, you are using SaaS. Check out http://www.ibm.com/developerworks/cloud/library/cl-cloudservices3saas/ to learn more.

Platform as a Service (PaaS) is an application platform that allows developers to build and deploy applications without having to maintain an infrastructure. Check out http://www.ibm.com/developerworks/cloud/library/cl-cloudservices2paas/ for more information.

Infrastructure as a Service (IaaS) uses a cloud provider to provide datacenter hardware needed. The provider will host servers for a business. They are able to increase and decrease the size of the servers in a very short time period. Businesses just pay for what they use.

Week 2 Blog Entry - What is the Cloud

What is the Cloud?

The easy explanation is the cloud is where you access programs or data over the internet instead of storing everything on your hard drive. Sometimes, you will be all in the cloud and others you might partially be in the cloud. For example, you use Microsoft Office products that have been downloaded to your desktop or laptop, but you store your documents in One Drive or Google Drive. The drives are utilizing the cloud. If you exclusively use Microsoft 365 online and don’t download the application, you are utilizing the cloud for those.

You may not realize how much you use the cloud. Anytime you access your email on the web, if you use Apple iCloud, and if you use any of the Google products (Drive, Photos, email, Google Apps, etc.), you are using Cloud technology. Even Facebook and Instagram could be considered cloud services because of the way they handle your photos. With the use of Carbonite to back up my desktop for several years, I’ve been using the cloud for backups.

Next week, we’ll talk about the differences with businesses using the cloud.

Week 1 Blog Entry - BSIT 400 Cloud Computing and Governance

Hello.
I'm Krista and I'm taking Cloud Computing and Governance through Bellevue University. This is one of the few classes that I have left towards a Bachelor of Science in Information Technology.

I'm finding that The Cloud is in more places than you think. I am an IT capacity planner for distributed systems. I work with virtualized servers, which are basically cloud based. I use Microsoft 365 and Google drive and email.

It will be interesting to learn more about cloud computing as I go along with this class.
