Yes, we know, we’re back talking about that old chestnut ‘the Cloud’ again. But it’s important that we do. It has the capacity to change the way television production works so we’ll keep coming back to it.
For the purposes of this blog, ‘the cloud’ is defined as online computing that allows users to access, via a web browser, applications and data that are installed and stored on a server somewhere else in the world.
Right now we’re going to look at the differences between private and public cloud.
It’s fair to say that there are varying degrees of difference but the major way that we differentiate between public and private cloud is in the location of the cloud’s deployment.
These are the two extremes:
If cloud services are available over the Internet for anyone to buy and use, this is public cloud. If the services are found behind a firewall and are looked after by a single company for the benefit of that company, it is private.
To coin a phrase, it’s all about location, location, location.
If you’re sold on the idea of using the cloud but you don’t know which of private or public is best for you, here are some of the Pros and Cons of both the public and the private cloud.
Pros of public cloud
- You have no need to buy expensive storage or software so your up-front costs are minimal
- You pay for your cloud services on a month-by-month basis
- A third-party is responsible for providing all the technologies required for your cloud-based services.
- You only pay for the bandwidth and storage you use
- You can store a myriad of different types of data in what appears to the end-user to be the same location.
- You can access your data and applications from anywhere in the world that has an Internet connection.
- The cloud services can be tailored for you according to your needs.
- Because of extensive back-ups and redundancy public cloud, should be more reliable than private cloud.
Cons of public cloud
- You have no control over the cloud service’s basic operations.
- If you store your data for a long period of time, it can end up being expensive.
- Because your data could be held outside of your geographical area, sometimes on servers in countries with different data, security and privacy laws and requirements, the public cloud is perceived to be less secure than private cloud.
Pros of private cloud
- You have full control over the cloud service’s basic operations.
- The service is bespoke to your company
- You control who does and who doesn’t use it.
- It is very easy to scale up and improve your cloud services.
- In the long term, the cost of operation can decrease.
- Your data is considered to be more secure.
Cons of private cloud
- You have high up-front costs.
- Your company has to buy, operate and maintain the technologies behind the cloud-based services.
- To extend the reach of your cloud-based services to people or companies beyond your own can be tricky.
- Because of the firewall, gaining access to your data and applications from anywhere in the world is not as straightforward as it is when using the public cloud.
- Hopefully this has spurred you in to exploring more about the cloud and how it will benefit television production for you.
Popular cloud software services like Salesforce.com, Google docs and dare we say it, Aframe, are somewhere in between the two; offering a public service on a private cloud. With these kinds of products, you get the best of both worlds.
