Cloud computing is an advancement in technology that allows users to store and access data and programs over the internet instead of on a hard drive. It is more accessible and easier to use than traditional hardware, and it helps companies stay at the forefront of technology. One subset of cloud computing, cloud hosting, is another method to help companies that gives users the option of using virtual servers to provide hosting solutions.
With cloud computing, there are multiple types of services. Software as a Service (SaaS) programs include programs such as Salesforce, Google Apps, and GoToMeeting. Software is hosted on a remote server and is always accessible through an internet browser. For companies that need to create software, a Platform as a Service (PaaS) lets developers concentrate on software building without dealing with updates, operating systems, and storage. And Infrastructure as a Service (IaaS) delivers cloud computing infrastructure like servers, a network, and operating systems. Organizations can buy resources as a service on demand.
A Deeper Look into the Cloud
- What is cloud computing?
- Cloud computing means storing and accessing data and programs over the internet instead of your computer’s hard drive
- Delivers computing resources (hardware and software) over the internet
- Also described as an Internet Centric Software
- Benefits include:
- 24/7 access to data
- Works on any device
- Accessible from anywhere with an internet connection
- Automatic upgrades to the latest version
- Improved data liability and security
- Large collection of free software
- Only pay for what you use
- Faster deployments
- Subscription-based pricing
- No IT staff required
- Cloud computing means storing and accessing data and programs over the internet instead of your computer’s hard drive
- What is cloud hosting?
- The process of using virtual servers to provide hosting solutions instead of a single server setup
- Benefits include:
- Affordability
- Little or no expensive equipment needed
- The provider handles regular maintenance
- Charged on a by-use scale
- Fast setup
- No installation time—no machines to purchase
- Quickly available for use after ordering
- Reliability
- Uses multiple (redundant) servers
- If one server has an issue, a redundant server immediately takes over so your website or IT infrastructure sees no downtime
- Improved productivity
- The provider handles server maintenance and security updates
- A business’s IT department can focus on other tasks
- Fully scalable
- As your company grows, your hosting needs may change
- Easily increase your access and scale up your service as necessary
- Better physical security
- Digital security and regular maintenance ensure safety
- Your information is completely safe
- Cloud hosting servers are housed inside secure data centers
- Multiple locations
- Some cloud providers have multiple data centers
- Allows you to choose the one that is closest to you
- Ensures maximum speed and security
- Customizable
- Easy to customize to get what you need
- Get the service you need by selecting the:
- Operating system
- Processing power
- Storage space
- Bandwidth
- Affordability
- There are two types of cloud hosting
- Private
- Designed and operated for a single entity
- Used as either a kind of intranet setup or external
- Generally more secure
- More maintenance
- Larger investment
- Public
- Rendered entirely on networks open to the public
- Could be as basic as a website hosting or digital data storage
- Overall architecture is similar to a private one
- Has less maintenance
- Has slightly less security
- Access is usually available through the internet
- Private
