In this video, Sharon will explore what the "cloud" really is. We will cover the myths, the reality, and the differences between the public, private cloud, and hybrid cloud.
- [Instructor] Your company, as a dynamic being, is going to morph, expand or even shrink. And as your needs change, you can use cloud technologies to assist in this process. We can use cloud technologies for full infrastructure if we wish, to maybe only hosted email. Cloud technologies can take your business to that next level. If you're a small business now, Cloud technologies allow you to leverage those big business tools that were never available to you typically because of cost. And if you're already a large business, leverage the Cloud to expand your current capabilities.
We as an industry have made the Cloud seem like this magical place, where all your data is safely stored and you can access it from anywhere at any time. We make it sound like it's all unicorns and fairy dust and all you need to do is move your data and never have to worry about it again. Yes, using the Cloud makes your life easier, but there's some details that you must understand before jumping in feet first. The reality is Cloud deployments require the same care and protection as your on premise deployments.
Just because we're using someone else's data center doesn't mean we forget everything that we do on premise. We don't forget those best practices. And just because these data centers are managed by let's say Google, or Amazon, or Microsoft, doesn't mean that you still don't have to take the time to understand how to leverage these properly. Before moving forward, there are three terms I want to explain a little bit. The first term is Private Cloud, which is a data center your company owns. Next, we have Public Cloud. This is a data center that somebody else owns, again, it could be a Microsoft or an Amazon.
And finally there's Hybrid Cloud. This is a combination of both. You're going to have some data on prem, you're going to have some data in someone else's data center. And each of these models has its own advantages and disadvantages. Let's start off with Private Cloud. This is a data center that your company owns and manages. In the Private Cloud model, your company is responsible for that data center and all the accompanying costs and services that are associated with that data center. You are responsible for procuring and managing all the hardware, to patching and updating all those servers, and controlling the security, and even overseeing the physical building itself.
Your data is kept within the data center under your control. Managing your own data center can be an expensive option and for some companies, it may be out of budget. The alternative to that Private data center is a Public data center. In this scenario, the data center is owned by Amazon or Microsoft, and they are responsible for maintaining that environment. That means you don't have to go and procure any hardware. Microsoft or Amazon is doing that for you. They take care of all the heating and cooling.
They are also responsible for all the patching of those servers. For you, this means you're moving from a capital expense because you're no longer procuring the hardware, to an operating expense because Microsoft or Amazon is now managing that for you. Essentially, you're renting the data center. One of the biggest benefits of the Public Cloud is that you're only going to pay for what you use when you use it. And finally, we have Hybrid Cloud. This is the best of both worlds. We're leveraging your data center and then we're tying into a public data center.
Using the Hybrid model allows you to balance workloads, and therefore balance cost as well. At this point, you may be thinking, which data center option is best for me? Well, the answer will depend on your needs. You may choose Private Cloud for your sensitive data, and a Public Cloud because of the ease of deployment. The Hybrid model tends to be the most popular, allowing you to leverage your existing data center, for those critical or private workloads, but utilize the Public Cloud for test and dev scenarios or as an extension of your current data center for those non-critical workloads, such as data storage or disaster recovery.
