Hello folks, Cloud Computing is becoming an essential skill for any Software developer or IT professional today as more and more companies are moving towards Cloud for their infrastructure and service needs.
It pays to learn Cloud Computing_ today_ as the most likely application will be solely building and deploy in the cloud in the future.
No matter what your role is, if you are working in technology, cloud computing is going to affect you, one way or another.
Anyway, if you want to learn cloud computing then you have come to the right place, in this article, I am going to share some of the best courses to learn Cloud computing basics in general and with AWS and GCP in particular.
To be honest, I have had a tough time finding an excellent course to learn Cloud Computing, after trying a handful of courses on Udemy, Pluralsight, Educative, and Coursera, I have finally zeroed down into following five directions to learn the basics of Cloud Computing.
These courses provide a broad introduction to all aspects of cloud computing, but before going to see these courses let’s first understand what is cloud and what benefit it provides? What problem cloud solves, and why is there so much buzz about it?
Well, Cloud has a different meaning for different people and also used to refer different things in a different context, but in general, cloud means a host of services that are ready to use for your application. There are many Cloud service provider companies like AWS (Amazon Web Service), GCP (Google Cloud Platform), and Microsoft Azure, which provides these services.
Now, what are those services? Well, these could be servers, networks, storage, computing power, and other infra related services commonly offered and referred to as IaaS (Infrastructure as service).
There are other cloud models as well, like **PaaS **(Platform as Service) and **SaaS **(Software as service) which is nothing but Cloud application and very popular for building online products and startups, but let’s focus on IaaS first to understand the benefits provided by Cloud.
Not long ago, in order to host a real-world E-commerce application, you need to buy servers, networks, storage and need to set them up to your requirements like installing the required software and operating system. Most of the companies have their own Data Center where these servers are kept, and there was a high cost involved to keep those data center running.
It was just initial time and cost for setting up the server, but also their utilization was poor; for example, secondary servers are often idle just wasting that precious CPU and memory power. The effect was more evident on big companies which own thousands of servers across multiple data center on the world.
Amazon was one such company, which quickly realize that by using virtualization, they can use the computing power of their infrastructure, and that gives birth to the cloud.

A multi-cloud approach is nothing but leveraging two or more cloud platforms for meeting the various business requirements of an enterprise. The multi-cloud IT environment incorporates different clouds from multiple vendors and negates the dependence on a single public cloud service provider. Thus enterprises can choose specific services from multiple public clouds and reap the benefits of each.
Given its affordability and agility, most enterprises opt for a multi-cloud approach in cloud computing now. A 2018 survey on the public cloud services market points out that 81% of the respondents use services from two or more providers. Subsequently, the cloud computing services market has reported incredible growth in recent times. The worldwide public cloud services market is all set to reach $500 billion in the next four years, according to IDC.
By choosing multi-cloud solutions strategically, enterprises can optimize the benefits of cloud computing and aim for some key competitive advantages. They can avoid the lengthy and cumbersome processes involved in buying, installing and testing high-priced systems. The IaaS and PaaS solutions have become a windfall for the enterprise’s budget as it does not incur huge up-front capital expenditure.
However, cost optimization is still a challenge while facilitating a multi-cloud environment and a large number of enterprises end up overpaying with or without realizing it. The below-mentioned tips would help you ensure the money is spent wisely on cloud computing services.
Most organizations tend to get wrong with simple things which turn out to be the root cause for needless spending and resource wastage. The first step to cost optimization in your cloud strategy is to identify underutilized resources that you have been paying for.
Enterprises often continue to pay for resources that have been purchased earlier but are no longer useful. Identifying such unused and unattached resources and deactivating it on a regular basis brings you one step closer to cost optimization. If needed, you can deploy automated cloud management tools that are largely helpful in providing the analytics needed to optimize the cloud spending and cut costs on an ongoing basis.
Another key cost optimization strategy is to identify the idle computing instances and consolidate them into fewer instances. An idle computing instance may require a CPU utilization level of 1-5%, but you may be billed by the service provider for 100% for the same instance.
Every enterprise will have such non-production instances that constitute unnecessary storage space and lead to overpaying. Re-evaluating your resource allocations regularly and removing unnecessary storage may help you save money significantly. Resource allocation is not only a matter of CPU and memory but also it is linked to the storage, network, and various other factors.
The key to efficient cost reduction in cloud computing technology lies in proactive monitoring. A comprehensive view of the cloud usage helps enterprises to monitor and minimize unnecessary spending. You can make use of various mechanisms for monitoring computing demand.
For instance, you can use a heatmap to understand the highs and lows in computing visually. This heat map indicates the start and stop times which in turn lead to reduced costs. You can also deploy automated tools that help organizations to schedule instances to start and stop. By following a heatmap, you can understand whether it is safe to shut down servers on holidays or weekends.

The impact of cloud computing on industry and end-users would be difficult to overstate: many aspects of everyday life have been transformed by the omnipresence of software that runs on cloud networks. By leveraging cloud computing, start-ups and businesses can optimize costs and increase their offerings without purchasing and managing all the hardware and software.
Independent developers are empowered to launch globally-available apps and online services. Researchers can share and analyze data at scales once reserved only for highly-funded projects.
And internet users can quickly access software and storage to create, share, and store digital media in quantities that extend far beyond their devices’ computing capacity. This gives a boom to better products and services without any worries about the hardware requirements.

The moving of applications, databases and other business elements from the local server to the cloud server called cloud migration. This article will deal with migration techniques, requirement and the benefits of cloud migration.
In simple terms, moving from local to the public cloud server is called cloud migration. Gartner says 17.5% revenue growth as promised in cloud migration and also has a forecast for 2022 as shown in the following image.
