Can You Ignore Cloud Computing?

Why the Cloud Buzz?
In today’s modern era, Cloud Computing is rapidly driving the technology industry. There is a good chance that the apps we are using or the blog we are reading - be it from the mobile, desktop or smartwatches are running on Cloud. It has significantly improved the performance of applications over time. It has the potential of onboarding application at a faster pace and is the future of deploying our applications to servers. But is Cloud Computing really important for us or does it provide any benefit to our business?
Let’s understand this concept in detail and overcome this dilemma forever!

How Were the Systems Working Without Cloud?
Let us imagine that we are working on a traditional system. A typical web server contains a system which contains a RAM of some memory allocated for processing, CPU, and disk with required capacity for data storage. The server has also need of operating system software which sits on top of this hardware. The operating system is then used to deploy and run the application software that we have developed that delivers some sort of specific functionalities that caters to the needs and provides services to our users. Apart from that we also require an electric power supply that can power up these systems and also good bandwidth active Internet connections running all the time in order to interact with the users on the other side of the system and provide them with an interface to the application.
Once all these setups are ready then only the users will be able to connect with our server and interact with our application that we deployed and explore its functionalities. An important point to note here is that all of these hardware setups resides in a data center and hence the responsibility of managing, maintenance and other technical aspects of these infrastructures solely lies with us that is the owner of these hardware.
So, this summarizes how a traditional architecture looks like and how the working of an application has some prerequisites. It is completely depended on this in-house installation and setups of the hardware and their configurations.
Are There Any Limitations With The Traditional Style?
Since we are managing our server in our own in-house data center, this setup has certain limitations. Some of them are:
Hence, Cloud Computing was invented in order to mitigate all such issues which are difficult to handle in-house and requires a dedicated team to take care of, and a lot of investments. These Cloud services are provided by the Cloud providers and there are three major players i.e. Amazon Web Service, Google Cloud, and Microsoft Azure. There are other players are well who are doing good in the market and offering similar services, but its upon us to decide as to what fits us best.
So, Does the Cloud Computing Has A Solution To This?
Cloud Computing brings in a change and provides a lot of flexibility to us by getting rid of this in-house data center that we discussed. Let us explore in detail what benefits does the Cloud brings us and why do we really need to move to the Cloud ecosystem.
There are numerous benefits that the Cloud has to offer us. Most of these are good resolutions to the limitations with the traditional system that we discussed.
a) It eliminates the need to have any physical system and hardware in our data-center. All these are hosted by the Cloud providers in their own data centers.
b) They are responsible for managing and maintenance of these hardware systems, be it the software updates, increasing the capacity or installing patches.
c) It gives us the flexibility to use these systems on a rent basis and pay only for the used capacity or duration.
d) The upgrading of the memory or storage in future or requesting for some additional resources can be done almost instantly.
e) We don't have to worry about scaling our applications during spikes as the Cloud takes care of them by offering us with various auto-scaling options.
Is the Cloud Flexible and Easy to Use?
Another major advantage of having a Cloud in place is that all these services that are offered by the Cloud can be accessed easily and hassle-free. The interaction can be done either with the user-friendly dashboard console, REST API or command-line interface given by the Cloud provider. It also provides us with a detailed metric to analyze the usage of our resources, monitor our application performances and run regular system health checks.
Is There Anything Else Prominent About Cloud?
Since the responsibility of managing these infrastructures is not in our control now and is taken care of by the Cloud provider. These Cloud providers ensure high availability and durability of the system and also offers disaster recovery options, which comes to great help in case of emergency or system failures. The Cloud provider hardware and services span the globe, and hence they ensure us that we are getting good coverage across the globe. These Cloud services are interconnected via Cloud provider mechanisms or Content Delivery Network (CDN) that we don’t have to be concerned about. Since there are many such systems deployed across the globe by these Cloud providers, the issues for geolocation and latency is also resolved. So, for example, a user present in Sydney can easily interact with an application in hosted either somewhere in America or Asia without facing any issues with the network in terms of latency. Hence our users are happy with the application performance globally.
Conclusion - Can We Ignore Cloud Computing?
It has been a long time since the Cloud was invented and it is ever-growing and serving a lot of users around the world. The constant innovation in this field has led to the emergence of many new Cloud providers that provide similar services and are targeted to small scale industries to reduce their cost further. This has led to a huge competition amongst the various Cloud providers. As per various study and research in the industry, it has been identified that there is still a major need for the Cloud to fulfill the needs of the companies in an efficient manner.
We have seen that the Cloud brings in flexibility and has many advantages over the traditional infrastructure setup, but despite its benefits, that question that pops in our minds: Is this really for me? or Should I go ahead with Cloud or sometimes simply Can We Ignore Cloud Computing? The answer is simple. The future of the Cloud industry is going to be more robust and soon the majority of the technology will move to the Cloud. So, it is a need of the hour to keep our systems updated in order to grow our businesses and stay upfront in the market.
It has helped many companies across industries to scale their business and maximize profits. There are many organizations who are planning to adopt the Cloud ecosystem but are facing scarcity of this talent in the industry. This leads them to hire professionals by offering them great pay scale. Hence, it brings a good opportunity for working professionals to scale themselves by acquiring the essential skills in the Cloud.
The online courses help these professionals who are looking to explore the Cloud but are facing time crunch due in their regular job responsibilities. These online courses deliver all the required knowledge with rich content and hands-on practice sessions and make us comfortable when working with real systems. The possibility of Cloud is infinite both for the companies as well as the professionals in terms of growth and technological expansion.
