What are the Prerequisites to Learn Cloud Computing AWS ?

There are certain prerequisites when you want to learn AWS. But let’s first understand what AWS is:

What is AWS?

AWS stands for Amazon Web Services. It is an all-inclusive and secure cloud services platform provided by Amazon. Offering a broad range of infrastructure services is the key speciality of AWS Cloud. These services encompass computing power, storage alternatives, databases, and networking. All these offerings help businesses to grow.  Initially, it may seem confusing to learn the new technology. Some IT professionals may doubt whether the base knowledge they have is sufficient to learn AWS or not.  Therefore, it is essential to know what the pre-requisites are to learn AWS certification courses. 

What are the pre-requisites to learn AWS?

If you want to delve into a cloud computing course, you need to first know what prerequisites are required. This is the most fundamental question that confuses most of the IT professionals willing to enhance their career in cloud computing. It is necessary to stay away from the myths and focus on the pre-requisites you need.  While discussing the skills needed to learn AWS, the following sections also try to eliminate the false assumptions around the same.

 "Cloud Computing" is a term that covers various concepts of the IT sector. It basically revolves around the areas like hardware infrastructures, software infrastructures, data center facilities, software engineering topics, and virtualization technologies.

Following are some of the major prerequisites:

• Fundamental knowledge of operating systems like Windows, Linux, etc.
• Fundamental knowledge of Networking and Virtualization
• Knowledge of any programming language
• Fundamental command on coding (because certain auxiliary software may need it)
• Overview of Public and Private cloud

Now let’s look into detail about some of the key prerequisites for AWS:

Knowledge of Operating Systems:

Since Amazon cloud is an umbrella term, you must be aware of the fundamental concepts associated with operating systems like Linux, Windows, etc. You need to know how these OS work and what if they are operated at a high level.

It is essential to learn the Linux operating system. This is because the majority of the organizations that function with scalable environments and web applications prefer Linux. Moreover, Linux is also the key preference for using an Infrastructure-as-a-Service (IaaS) platform like the AWS platform. The most effective way to learn Linux is to go through the documentation and courses online. Once you acquire the fundamental knowledge of Linux OS, you can start using it. To learn AWS Step by Step, it is beneficial if you know the fundamentals and working of Linux operating system.

Familiarity of Virtualization:

After you get familiar enough with the operating systems, the next step is to get familiar with Virtualization Technology. In the AWS learning path, virtualization plays a major role. This technique houses and executes multiple operating systems i.e. virtual machines into a single physical machine. Furthermore, every virtual machine comes with precise RAM, CPU, and disk space capacities. They all run their operating system. 

Keep in mind that virtual machines share the same network tools and same hardware. They are only virtually separated from each other.

Understanding of Networking:

One of the vital elements of Amazon Cloud is networking. This is since every operation within a cloud platform uses networking. To get started, initially, you must know how IP addresses function. You need to understand the meaning of private and public networks. The reason is later on in the AWS learning path, you will come across these terminologies. If you lack basic knowledge of these terms, then it will create a huge issue.

Every cloud instance must be connected to the Internet. It can be daunting and difficult to master each networking concept. You need to have high-level skills that need considerable time. However, it is sufficient if you have a basic understanding of networking and the terms described above.

Now let’s look at the prerequisites required for each of the AWS certifications:
