What is the cloud? Where is the cloud? Are we currently in the cloud? These are all the questions you have probably heard or asked yourself. The term “cloud computing” is everywhere. In its simplest sense, cloud computing means storing and accessing data and programs on the Internet instead of your computer’s hard drive.
Cloud computing is not about your hard drive. When you write data or run programs from your hard drive, this is called local and computer storage. Everything you need is physically close to you, which means that accessing your data is quick and easy for this computer or another on the local network. Working on the hard drive has been the way the computer industry has operated for decades. Some would argue that it is still superior to cloud computing for reasons that I will explain shortly.
The cloud does not mean having a dedicated Network Attached Storage (NAS) in your home. Storing data on a home or work network does not count as cloud usage. (However, some NAS devices allow you to access things remotely over the Internet, and there is at least one Western Digital brand called “My Cloud” so as not to confuse things.)
To be considered “cloud computing,” you must access your data or programs on the Internet, or at least synchronize that data with other information on the web. In a large company, you can know everything you need to know about the other side of the connection. As a single user, you may never have an idea of the type of massive computing that occurs in a data centre that uses more electricity per day than your entire city in a year.
General cloud examples
When it comes to home use, the lines between local computing and cloud computing are sometimes blurred. This is because the cloud is part of almost everything on our computers today. You can easily use local Software (for example, Microsoft Office) that uses some form of cloud computing for storage (Microsoft OneDrive). Microsoft also offers several web applications, Office (also known as Office for the web), which are web-only versions of Word, Excel, PowerPoint, and OneNote that you can access through your web browser with nothing to install. This makes it an understanding of cloud computing (web-based = cloud).

Benefits of Cloud Computing
The cloud offers easy access to a wide range of technologies so you can innovate faster and create almost anything you can imagine. You can quickly scale resources as needed – from infrastructure services like computers, storage, and databases to the Internet of Things, machine learning, data lakes and analytics, and more. Besides that.
You can deploy technology services in minutes and go from idea to implementation is orders of magnitude faster than ever. It gives you the freedom to experiment, to test new ideas to differentiate customer experiences and transform your business.
With cloud computing, you no longer need to allocate resources in advance to deal with future business peaks. Instead, you are providing the number of help you need. You can instantly expand or contract these features to increase and decrease capacity as your needs change.
With the cloud, you can exchange capital costs (such as data centres and physical servers) for variable expenses and pay the IT department only when using them. Also, due to economies of scale, the variable cost is much less than what you would pay for yourself.
Deploy globally in minutes
With the cloud, you can expand to new geographies and deploy globally in just minutes. For example, AWS has a global infrastructure that allows you to deploy your application to multiple physical locations with only a few clicks. Bringing apps closer to end-users reduces latency and improves user experience.

Types of cloud computing
Cloud computing offers developers and IT departments the ability to focus on the essentials and avoid undifferentiated work, such as provisioning, maintenance, and capacity planning. As cloud computing has become more popular, different deployment models and strategies have been developed to meet the specific needs of other users. Each type of cloud service and delivery method offers different levels of control, flexibility, and management. When you understand the differences between infrastructure as a service, platform as a service, and Software as a service and the deployment strategies to use, you can decide which services are right for your needs.
Infrastructure as a Service (IaaS)
IaaS contains the fundamentals of cloud computing. It usually provides access to network functions, computers (virtual or on dedicated hardware), and data storage space. IaaS offers maximum flexibility and management control over your IT resources. It is very similar to the existing IT resources that many IT departments and developers are familiar with.
Platform as a Service (PaaS)
With PaaS, you no longer need to manage the underlying infrastructure (typically hardware and operating systems) and can focus on deploying and managing your applications. That way, you can work more efficiently because you don’t have to worry about resource provisioning, capacity planning, software maintenance, patches, or other undifferentiated tasks associated with running your application.
Software as a Service (SaaS)
SaaS offers a complete product that is run and managed by the service provider. In most cases, people who refer to SaaS are referring to end-user applications (for example, webmail). With a SaaS offering, you don’t have to worry about how the service is maintained or how the underlying infrastructure is managed. All you need to do is think about how to use this specific Software.
Consumer vs. The business
Let’s be clear here. I’m talking about cloud computing because it affects individual consumers – those of us who stay at home or in small to medium-sized offices and regularly use the Internet.
There is an entirely different “cloud” for business. Some companies choose to implement Software as a Service (SaaS), in which the company signs an application that it accesses over the Internet. (Think Salesforce.com.) There is also a platform as a service (PaaS), which a company can use to create its custom applications that anyone in the company can use.
Cloud computing is big business. Our partners at Statista created this chart in February 2020 that shows Amazon’s dominance in the $ 100 billion a year industry. That was, of course, a month before the COVID-19 coronavirus shut down many companies – which then moved their homes to cloud computing for the most part.

Why should you choose AWS as a career?
Spending on public cloud infrastructure and services will more than double, from $ 229 billion in 2019 to about $ 500 billion in 2023, according to IDC. This corresponds to an average annual growth rate (CAGR) of around 22%. The main areas of public cloud investment for this five-year window of strong growth will be:
• Professional services (25.6%)
• Telecommunications (24.1%)
• Retail trade (23.7%)
• Raw materials industry (23.3%)
• Personal and consumer services (23.1%)
If you follow the money, you will see that a career in the public cloud has a bright future. Following the numbers is not enough reason to choose AWS as a career path. If you are feeling stuck in your current IT profession and looking for a new career, for example, you need to choose the right job for all the right reasons. In this article, we provide useful information to help you decide whether an AWS career is the right decision for you.
In no time, Amazon Web Services certified professionals are among the highest-paid IT certification holders. According to a recent salary survey by Global Knowledge, the average salary for an authorized employee is $ 113,932, which can go up to $ 201,000.
