What is Cloud Computing technology?
The world is revolutionizing day by day. Every day a new technology emerges, be it artificial intelligence, machine learning, IoT, blockchain, or cloud computing. Gone are the days when we had to carry USBs, hard drives, and floppies to carry stored files with us.
Cloud computing has made sure that we have access to our stored data anywhere and anytime. Many companies and businesses are also benefiting from this cutting-edge technology named “cloud computing”.
In this article, we will discuss what cloud computing is, its benefits, how it works, and its types.
What is cloud computing? How does it work?
Cloud computing is basically a technology that offers computing services like secure and safe data storage, networks, analytics, intelligence, and servers over the internet.
Cloud computing allows you to store and access the data over the internet and not on the hard drive of your computer. From saving pictures and personal data on Dropbox to watching Netflix all is dependent on the cloud.
The word “Cloud” in term cloud computing arises questions in the minds of many. Well, the cloud is just a metaphor used for the internet. Instead of buying resources and creating an IT infrastructure of your own, you can just share the resources through a network called internet connection.
There are several cloud computing providers such as AWS, Azure, IBM, and Google Cloud Platform. These providers maintain and store the information on servers (both physical and virtual). You only need an internet connection to access the information stored on these servers.
Cloud computing is generally divided into two main sections that are the front end and back end. The front end is intended for clients and it serves as a user interface.
Different cloud computing service providers have different user interfaces. The front end comprises the user’s computer and the application necessary to access the cloud. On the other hand, the back end consists of servers, storage systems, and computers which comprises the cloud. Both ends are connected through a network which is mostly the Internet.
Now that we understand what cloud computing is, let’s see why we need it in our lives.
5 Benefits of cloud computing
In recent years, we have seen a major shift in business moving towards cloud computing. That’s because of the tremendous benefits that come with cloud computing.
Cloud computing allows you to save costs because you don’t have to invest in the IT infrastructure of your own. This means you don’t have to worry about the cost of 24/7 electricity supply, managing team, servers, and location. Instead, you can invest the saved costs in new business ideas and projects which is a lot more beneficial.
2. Efficient scalability and operational agility
Cloud computing provides you the most efficient services by providing vast amounts of computing resources within minutes. In this age of competition, you can instantly manage and balance the cloud capacity according to the demand. If the demand is high, you can increase the computing resources and capacity with a couple of clicks. This improves the operational agility of an organization and also the profits.
3. Global Reach
No matter if you are using cloud computing for business needs or personal use. If you have an internet connection, you can access your files, photos, and important documents from anywhere in the world. You can share the documents with employees with the single click and you don’t have to travel miles for just delivering or signing an important document. You can do it simply by using the cloud.
Cloud computing enables you to live life without fearing the loss of important data or files. We are not living in an era where if the USB is lost or hard drive gets corrupt we lose all the data. Cloud computing makes backup and recovery of your data easier than ever before by allowing you to mirror it on different sites within the cloud service providers network.
Cutting edge technology of cloud computing makes sure that your data is protected from cyber-attacks and potential threats. Cloud computing offers advanced security features that have reduced the chances of your sensitive data being exposed to hackers.
Types of Cloud Computing Deployments
Cloud computing offers different types of clouds to cater to your needs. Basically, there are three types of clouds. Let’s have a look at what cloud type suits you the best.
In the public cloud, the cloud service provider offers resources like storage, virtual machines, applications, etc. to the public via the internet. Resources depend on the cloud service provider you are using.
Individuals, as well as organizations, can use public cloud. Some resources are available for free while others need a subscription or are charged using a pay-per-usage model. It allows you to save money because you only pay for what you are using, and it also reduces the need for personal IT resources. Public clouds enable resource sharing and scalability which is a good way to cope with market and customer demand.
Private clouds are mainly intended for business entities. In a private cloud, businesses enjoy an exclusive environment and resources provided by cloud service providers. A private cloud provides extensive virtualized computing resources through physical components accumulated at the vendors’ location or datacenter.
Organizations have full control over the cloud because no one else is sharing the cloud with them so they can configure and manage the environment according to the needs of their business. The private cloud provides more security and control. However, you may need to invest in hardware resources.
A hybrid cloud is a combination of a private cloud with one or more public clouds. The number of public clouds depends on your needs. For the hybrid cloud, there needs to be an exclusive software to enable communication between private and public clouds.
Hybrid Cloud allows businesses to move loads between private and public clouds depending upon the needs and costs because costs and needs are the two most fluctuating factors in any business. You can take advantage of the private cloud by storing private data on it to have better control and secrecy.
While on the other hand, you can also utilize robust computational resources provided by the public cloud. This is the most cost-efficient cloud type for businesses and startups because it also saves your local resources from straining and you don’t need to invest in and develop huge datacenters at your facility.
Types of Cloud Computing Services
When it comes to types of cloud computing services, the 4 most commonly used types are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Let’s have a look at each of these types.
In IaaS, external cloud service providers offer and manage the virtualized infrastructure for businesses. In infrastructure as a service (IaaS), organizations and businesses can outsource computing resources like storage, servers, space for data centers, etc. These resources only need an Internet connection to provide functionalities similar to on-site infrastructure.
Automated operations such as clustering, hosting, networking, backup, and recovery are some examples of IaaS. Almost all of the famous cloud service providers offer IaaS and they are responsible for building physical data centers, storage, servers, and firewalls. IaaS is a cloud-based service and it follows a pay-as-you-go pricing model. Some examples of IaaS are AWS EC2, Rackspace, Google Compute Engine (GCE), Digital Ocean, and Magento.
In PaaS, cloud service providers supply hardware and software resources required to develop, run, and test the applications. In platform as a service (PaaS), hardware and software tools like middleware, operating systems, etc. are available over the internet and cloud users can download, install, and host them except building the hardware part. PaaS is usually used by developers.
PaaS is the best option if you are a business owner who wants to create unique software and applications without spending a lot of money. Some examples of PaaS are AWS Elastic Beanstalk, Heroku, Windows Azure, Force.com, OpenShift, Apache Stratos, and Magento Commerce Cloud. PaaS incorporates IaaS.
In SaaS, cloud service providers supply the complete software via the Internet. SaaS incorporates both IaaS and PaaS and it uses a pay-per-use pricing model. The best thing is that you do not have to download, install, and run software applications on the computer because all are available on the Internet you just have to log in to your account. Some SaaS examples are BigCommerce, Google Apps, Salesforce, Dropbox, MailChimp, Zendesk, DocuSign, Slack, and HubSpot.
Now that you know all the basics of cloud computing, it is essential to keep in mind that you can’t use every cloud service provider that pops up. Before selecting a cloud service provider, study the services provided by the vendor so that you know if it meets your business objectives.
