Cloud Computing: A Bundle of Benefits
Cloud computing is the use of computing services like servers, databases, networking, storage etc. over the internet. It provides several attractive benefits to businesses and end-users and guarantees a secure environment.
The cloud computing services run on the worldwide network of secure data centres, which are regularly upgraded to the latest and efficient computing hardware.
If you want to learn more about cloud computing technology and services from beginning to depth, Intellipaat is one of the best options to complete the online cloud computing course.
Cloud computing services can be divided into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
Let’s have a quick look at these:
1. IaaS: A model in which third-party provider hosts servers, storage and other resources and makes them available through the internet. There are three different ways to deploy cloud computing resources: the public, private and hybrid cloud.
2. SaaS: A software distribution model in which third-party vendors host applications and make them available to its customers over the internet.
3. PaaS: Here, the third party provider hosts application development platforms and tools on its own infrastructure.
In a public cloud, the third party provider owns and manages all hardware, software and other supporting infrastructure. A private cloud is one in which the services and infrastructure are maintained on a private network. Hybrid cloud is the combination of public and private clouds that allows data and applications to be shared between them. Real world examples of cloud services include Dropbox, Amazon Web Services (AWS), Gmail, SkyDrive etc.
Benefits of Cloud Computing
Besides unlimited storage capacity, cloud computing offers a bundle of benefits. Some of the greatest benefits are ease of installation, low maintenance and scalability. Companies can scale up and scale down as per the computing needs. This way it grows with your needs. This enables users to pay only for the resources and workloads they use.
Cloud computing is a great cost-efficient option as it reduces IT expenses of companies by way of low energy consumption, pay-as-you-go, zero remuneration for expert staff etc. Cloud computing helps you to do away with the worries regarding storing your own data; because managing hardware and software is the responsibility of an experienced vendor. The hardware is completely managed by the cloud vendor. There are many cloud vendors such as Amazon, Google etc. who offer a range of cloud-based solutions.
The delivery of hosted services over the internet helps companies greatly as they need not build and sustain computing infrastructures in-house. Individuals, small businesses and global enterprises move to cloud-based services as they provide new ways to collaborate everywhere, through mobile devices.
Cloud computing backup gives strong disaster recovery, and your IT infrastructure is monitored 24/7. Even small to medium-sized businesses with resource constraints can avail of top-notch compute, storage and networking know-hows. Automatic software integration and upgrade is another benefit that Cloud Computing confers.
As the cloud has fewer operation issues, it is more reliable than on-location server.
Putting business on the cloud is a very smart option taking into account the range of benefits. It is indeed a great time, money and resource saver!
