Cloud computing is a general term for the delivery of hosted services over the internet. Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand .Cloud computing enables companies to consume a computing resource, such as a virtual machine (VMs), storage, or an application, as a utility — just like electricity — rather than having to build and maintain computing infrastructures in house. Cloud computing boasts several attractive benefits for businesses and end-users. The main benefits of cloud computing are:
Self-service provisioning: End users can spin up compute resources for almost any type of workload on-demand. This eliminates the traditional need for IT administrators to provision and manage compute resources.
Elasticity: Companies can scale up as computing needs increase and scale down again as demands decrease (Flexibility). This eliminates the need for massive investments in local infrastructure which may or may not remain active.
Pay per use: Compute resources are measured at a granular level, allowing users to pay only for the resources and workloads they use.
Disaster recovery: Businesses of all sizes should be investing in robust disaster recovery, but for smaller businesses that lack the required cash and expertise, this is often more an ideal than the reality.
Automatic software updates: The beauty of cloud computing is that the servers are off-premise, out of sight, and out of your hair. Suppliers take care of them for you and roll out regular software updates – including security updates – so you don’t have to worry about wasting time maintaining the system yourself. Leaving you free to focus on the things that matter, like growing your business.
Increased collaboration: When your teams can access, edit and share documents anytime, from anywhere, they’re able to do more together and do it better. Cloud-based workflow and file sharing apps help them make updates in real-time and gives them full visibility of their collaborations.
Work from anywhere: With cloud computing, if you’ve got an internet connection you can be at work. And with most serious cloud services offering mobile apps, you’re not restricted by which device you’ve got to hand. The result? Businesses can offer more flexible working perks to employees so they can enjoy the work-life balance that suits them – without productivity taking a hit.
Document control: The more employees and partners collaborate on documents, the greater the need for watertight document control. Before the cloud, workers had to send files back and forth as email attachments to be worked on by one user at a time. Sooner or later – usually sooner – you end up with a mess of conflicting file content, formats, and titles. When you make the move to cloud computing, all files are stored centrally and everyone sees one version of the truth. Greater visibility means improved collaboration, which ultimately means better work and a healthier bottom line. If you’re still relying on the old way, it could be time to try something a little more streamlined.
Security: Lost laptops are a billion-dollar business problem. And potentially greater than the loss of an expensive piece of kit is the loss of the sensitive data inside it. Cloud computing gives you greater security when this happens. Because your data is stored in the cloud, you can access it no matter what happens to your machine. And you can even remotely wipe data from lost laptops so it doesn’t get into the wrong hands.
Cloud computing deployment models
Cloud computing services can be private, public, or hybrid.
Private cloud services are delivered from a business’ data center to internal users. This model offers versatility and convenience while preserving the management, control, and security common to local data centers. Internal users may or may not be billed for services through IT chargeback.
In the public cloud model, a third-party provider delivers cloud service over the internet. Public cloud services are sold on demand, typically by the minute or hour. Customers only pay for the CPU cycles, storage, or bandwidth they consume. Leading public cloud providers include Amazon Web Services (AWS), Microsoft Azure, IBM SoftLayer, and Google Compute Engine.
Hybrid cloud is a combination of public cloud services and on-premises private cloud — with orchestration and automation between the two. Companies can run mission-critical workloads or sensitive applications on the private cloud while using the public cloud for bursting workloads that must scale on demand. The goal of hybrid cloud is to create a unified, automated, scalable environment that takes advantage of all that a public cloud infrastructure can provide while still maintaining control over mission-critical data.
Cloud computing service categories:
Although cloud computing has changed over time, it has been divided into three broad service categories: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS).
Some businesses choose to implement Software-as-a-Service (SaaS), where the business subscribes to an application it accesses over the Internet. (ThinkSalesforce.com.)
There’s also Platform-as-a-Service (PaaS), where a business can create its own custom applications for use by all in the company.
And don’t forget the mighty Infrastructure-as-a-Service (IaaS), where players like Amazon, Microsoft, Google, and Rackspace provide a backbone that can be “rented out” by other companies.
(For example, Netflix provides services to you because it’s a customer of the cloud services at Amazon.)
