Cloud Computing
by Ishita Singh and Ojasvi Bhushan
Today, 65% of the world’s population uses smartphones, computers, and tablets. All of these users may have come across the term cloud and use the cloud and its services, but most of them do not know exactly what “CLOUD” is. Since the cloud is part of our daily life like smartphones, computers, and tablets, we should know what it is, right?
When we first heard “cloud computing,” everyone thought it was related to the actual clouds in the sky and probably everyone thought “computing” was calculating or counting …. we’re right about what we mean by computing, but that’s not what the cloud (we’re initially thinking of) means loosely here, but rather the capabilities of the cloud. are being used to implement them in technology.
Cloud computing is used to provide all computing resources over the internet at an affordable price. We used to buy servers and data centres, but now instead of buying, owning, and maintaining physical servers and data centres, you can access technology services such as computing, storage, and database power, if needed, from a cloud provider such as Amazon Web Services (AWS).
Types of Cloud Computing
Cloud computing provides an opportunity for developers and IT departments to focus on what matters and avoid undifferentiated tasks such as procurement, maintenance, and capacity planning. With the popularity of cloud computing, different models and deployment strategies have emerged to meet the specific needs of different users. Different types of cloud services and delivery methods offer different levels of control, flexibility, and control.
We usually have three main types of cloud computing:
Infrastructure as a Service (IaaS)
The cloud is made up of many IaaS services. These services provide the basic building blocks for cloud IT. A network provides access to various features, including computers and data storage space. IaaS provides the highest level of flexibility and management control over your IT resources, allowing you to use them in the way that is best for your business. The software is similar to the software that many IT departments and developers are already familiar with.
Platform as a Service (PaaS)
PaaS eliminates the need to manage the underlying infrastructure (usually hardware and operating system) and allows you to focus on deploying and managing your applications. This will enable you to work more efficiently because you don’t have to worry about resource procurement, capacity planning, software maintenance, patching, or other undifferentiated heavy lifting associated with running your applications.
Software as a Service (SaaS)
Software as a Service is software distribution where software is hosted by a provider and made available to customers over the Internet. These applications are commonly referred to as web-based software, hosted software, and on-demand software. You can access SaaS applications from your web browser. A company can use APIs to integrate its SaaS application with other software. For example, Gmail, messaging software, etc.
Fact: Cloud computing services are usually collectivised by the name XAAS, i.e., Anything as a Service.
Who is using Cloud Computing?
Today, almost businesses of all sizes, types and industries use cloud computing. Even if you’re using Gmail, you’re using the cloud. Cloud computing is no longer a trend nowadays, it is becoming a fact, and even the government is moving to cloud computing for various reasons. Industries use cloud computing for a variety of use cases such as data backup, virtual desktops, email, software development, and testing, big data analytics, and web applications. client. for example, video game makers use the cloud to deliver online games to millions of gamers around the world. Healthcare companies are using the cloud to develop more personalised treatments for patients and more.
Benefits of Cloud Computing
1. Agility
The cloud gives you easy access to a variety of technologies, allowing you to innovate faster and create almost anything you can imagine. Quickly bring together the resources you need, from infrastructure services like computing, storage, and databases to the Internet of Things, machine learning, data lakes, analytics, and more. Deploy technical services in minutes and go from concept to execution of volume orders faster than ever before. It gives you the freedom to experiment and try new ideas to differentiate your customer experience and transform your business.
2. Elasticity
With cloud computing, you don’t need to provision resources upfront for future peak business. Instead, provide the number of resources you need. You can scale up or down these resources to scale up or down instantly as business needs change.
3. Cost savings
By using cloud infrastructure, you don’t have to spend a lot of money to buy and maintain equipment. You don’t need to invest in hardware or build a massive data centre to grow your business. You don’t need a large IT team to manage your data, you can take advantage of the services offered by the cloud service provider’s staff.
4. Deploy globally in minutes
With the cloud, you can expand into new territories and deploy globally in minutes. For example, AWS has a global infrastructure, so you can deploy applications to multiple physical locations with just a few clicks. By placing your applications closer to your end users, you can reduce latency and improve their experience.
