To meet ever-changing business needs, organizations need to invest time and budget to scale up their IT infrastructures such as hardware, software, and services. However, with these services, the scaling process can be slow, and organizations are frequently unable to achieve optimal utilization of the IT infrastructure.
Here when we talk about “Cloud Computing” it is a paradigm shift that provides computing over the “Internet". Why we need Cloud Computing? How does it work? It is a new emerging technology or something else? Just follow up on the article and you will know many more things about “Cloud Computing Technology”.
What is Cloud Computing
Cloud Computing is the delivery of “computing services” including servers, storage, databases, networking, software, analytics, and intelligence, over the Internet to offer faster innovation, flexible resources, and economies of scale. Typically you pay only for cloud services that you want to use, helping up to lower your operating costs, run your infrastructure more efficiently, and scale up your business needs change.
There are many things due to which this technology of IT is taking place at a large level. What do you want from technology? Of course, Productivity, Reliability, Speed, Performance, and Security. 2020 and the upcoming years will demand these things from technology because everyone wants low-risk profit, saves time and money too. Cloud Computing gives you all of them to ensure your needs and demands. Following are some of the characters of Cloud Computing which clear up your mind how it works and why it is the most in-demand technology?
- Cost: cloud computing eliminates the expenses of buying hardware and software and setting up. Just buy what you want and work on it. No need of wasting money on buying all IT things for the infrastructure of your business. Cloud Computing gives you a chance to own what you want.
- Speed: most cloud computing services provide self-service and on-demand, so even vast amounts of computing resources can be provisioned in mints, typically with just a few mouse clicks, giving the business a lot of flexibility and taking the pressure off capacity planning.
- Productivity: on-site data centers required a lot of racking and stacking hardware setup, software patching, and other time-consuming IT
management chores. Cloud computing removes the need for many of these tasks, so the IT teams can spend time on achieving more important business goals.
- Performance: the biggest cloud computing services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate data center, including reduced network latency for applications and greater economies of scale.
- Reliability: cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s networks.
- Security: many cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture overall, helping protect your data, apps, and infrastructure from potential threats.
Cloud computing offers different services models which satisfy businesses. Let's dig up its services.
Models of Cloud Computing
There are two types of models in Cloud Computing 1) “Deployment Model”, 2) “Service Model”. Let’s understand about Deployment Models.
You may have experienced Public bus while you go to the office or for some other work .Probably you take a bus to reach your destination. The public cloud is like this, it is accessible to anyone, you pay only for the resources you need from Cloud Computing, and you pay for how long you are going to use it.
It is like buying your own car, the private one and using it for commuting purposes. Here in this system of Cloud Computing, you are paying a lot of amounts and it is only owned by you. The cost here is huge. In simple words, it is owned by a single person.
If you want both of the best types this is a good option for you. Here you are going to take the example of a private taxi. Here you are only paying if we want to use it. It is the combination of functionalities of both public and private clouds. So you have a great choice between them.
1-Infrastructure as a Service (IAAS)
If all that you want is just a Virtual Reality(VR) and it has all the expertise to install the software on top of it and make it work then go for IAAS.
It is the most basic category of cloud computing services. With IAAS, you rent IT infrastructure servers and storage, networks, operating systems from a cloud provider on a pay-as-you-go basis.
2-Platform as a Service (PAAS)
PAAS refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. PaaS is designed to make it easier for developers to quickly create websites or mobile apps. Without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.
3-Software as a Service (SAAS)
SAAS is a method for delivering software applications over the Internet, on-demand, and typically on a subscription basis. With SaaS, cloud providers host and manage the software application, underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users connect to the application over the Internet, usually with a web browser on their phone, tablet, or PC.
Some of the Popular Cloud Computing Services
1-Amazon Web Services (AWS)
AWS can be used to create and deploy any application in the cloud. It provides services over the internet. It was launched in the year 2006. AWS has 69 availability zones within 22 geographic locations and as soon it will have more than in the future.
When it comes to pricing, in this condition the user can pay for what they use. It is the choice of the user what they want to use and they will pay for it only. AWS is the web service that helps to resize your computer capacity where you can run your application programs on a VR. For the first 12 months AWS provides free as a trailer.
It is a set of cloud services used to build, manage, and deploy applications on a network with the help of tools and frameworks. It was launched in the year 2010. Azure’s VR gives a user the ability to deploy and manage a virtual environment inside a virtual network on the cloud. It helps the user to create many identical virtual machines in a matter of minutes.
Blob storage offers large amounts of storage and scalability. It stores the object in the tiers, depending on how often data is being accessed. It is a strategy that allows site recovery by orchestrating and automating the replication process of Azure virtual machines between regions.
3-Google Cloud Platform
Google Cloud Platform is a cloud computing service that offers application development and integration services for its end users. It was launched in the year 2008. Google cloud platform is available in 200+ countries across the globe.
It enables a user to build, deploy, and manage virtual machines in order to run workloads on the cloud. It has a platform as a service. It is a service used by developers for building and hosting applications in google’s data center. It is the easiest way to run your code in the cloud. Also, it is highly available and fault-tolerant.
It provides unified objects storage for live or archived data. This service is used to store and access data on GCP infrastructure.
Benefits of Cloud Computing
You are probably using cloud computing right now, even if you do not realize it. If you use an online service to send an email, edit documents, or watch a movie it is likely that cloud computing is making it all possible behind the scenes. Here are a few examples of today’s cloud services from a cloud provider.
