Understanding How Cloud Software Works in 2021


Cloud computing has been growing in popularity rapidly for the last decade. Professionals like an AWS cloud developer or IBM cloud architect are in high demand all over the world. It offers many business benefits like cost efficiency and new tech opportunities.

According to the LogicMonitor study of 2020, 95% of the workloads will be in the cloud in the next 5 years. In the year 2020, the global market size of cloud computing reached $266 billion. And it is expected to grow. In this article, we’ll cover how cloud computing works, what benefits it offers, and what are some trends to look forward to.

Understanding How Cloud Software Works In 2021

#1 How Does Cloud Infrastructure Work?

Cloud solutions are extremely widely used by almost any person. For example, they are Gmail, Google Drive, Facebook, Instagram, etc. About 69% of businesses have already implemented it on some level. So what is it all about?

Cloud computing describes any type of service that is delivered via the internet. The infrastructure includes remote servers, databases, and networks. It can be any application that one accesses on their device that uses remote services for their operations.

There is no need to be close to the physical hardware that stores all the data. The information can be accessed from any place in the world as long as one has an internet connection.

The front end of cloud software is an application on a user’s device. The backend includes servers, computers, databases, and other tools that do the things.

Cloud infrastructure is used to describe all the components that are necessary for cloud computing, including both software and hardware tools. A cloud developer works in the realm of hardware, virtualization, storage solutions, and network.

#1 Hardware

Hardware means the physical servers that are taken care of by the hosting company (Amazon, Google, Microsoft, Oracle, etc). There is a variety of tools needed like switches, routers, load balancers, servers, and other equipment pieces.

#2 Virtualization

The term means the technology that separates physical servers (hardware) from their functions and services. A hypervisor solution abstracts the hardware’s resources (storage, memory, power). And when these resources are allocated they are called clouds.

#3 Storage

Storage refers to the way data is stored by a hosting company. It is usually stored on multiple disks. It also covers regular backups and data retrieval opportunities.

#4 Network

The physical network is made out of wires, routers, and switches. A virtual network can be created on top of that. Often cloud networks are broken down into many subnetworks with various levels of access and visibility.

#2 Cloud Software Benefits

Whether one chooses to work with AWS, Azure, GCP, or any other cloud platform, they share the same benefits.

#1 Cost-effectiveness

In the majority of cases, it is much cheaper to use cloud solutions than build a physical data center for a business. There is no need to buy hardware and hire personnel to take care of it. All of that is taken care of by the cloud provider. That’s why many small and middle-size businesses use it.

Another advantage is that such solutions work on a pay-as-you-go basis. So a company pays only for resources they use.

#2 Scalability

Cloud solutions allow easily scaling up or down when needed. This is another perfect option for growing companies. If they managed their own data centers, it would be a slow process of buying and managing new equipment as well as hiring more people. With clouds, it is a matter of minutes to access new resources. So even rapid jumps in a website’s audience are handled smoothly.

#3 Security

Providers treat cybersecurity as a top priority and implement the most advanced solutions. Such measures might not be accessible for small businesses otherwise. Providers take care of backups, data storage, and disaster recovery.

#4 Newest Tools and Updates

For huge cloud vendors, it is much easier to always update their machinery. They use the best hardware as well as software to ensure reliable and fast connection. And all the updates are handled automatically so users do not have to worry about a thing.

#5 Flexibility

One of the top benefits of such solutions is the flexibility it gives to a business. Employees can access data from any part of the world or work from home. A company doesn’t even have to have a physical office today; all the things can be taken care of remotely.

#6 Collaboration and Control

Employees, contractors, or third parties can now share the same work-related files. It is the same principle as in Google Docs. One can see the changes others proposed or made. Developers can work in the same framework. All of that increases collaboration, ensures version control, and makes business processes fast and efficient.

#7 Data Insight

Many cloud providers offer access to data analysis tools that allow getting more insights. The analytics are already built-in and can be used for strategizing or planning the growth of a company. One can get customized reports or implement data tracking solutions.

That’s why experts like an AWS cloud developer or GCP cloud architect are in such demand. They help companies to migrate to the cloud and enjoy the best features of these solutions.

#3 Types of Clouds and Services

Overall, there are three types of clouds one can choose from.

  • Public. It is a public platform that can be shared with other individuals or companies;
  • Private. A platform that is dedicated only to your services. It ensures a higher level of security;
  • Hybrid is a mixed solution when a fraction of data is stored publicly and other information is stored on a private resource or on-premise.

Cloud computing services also have several types that can influence a cloud developer cost:

  • Software-as-a-Service (SaaS). The most common type is when cloud services are available via the app or web browser (Google Docs or Dropbox). There is no hardware installation.
  • Platform-as-a-Service (PaaS) is a cloud-based environment for web app development and deployment. It covers the whole lifecycle of an app and has development tools (Windows Azure, Google App Engine);
  • Infrastructure-as-a-Service (IaaS) offers computer infrastructure with data storage, hardware, and servers in the cloud. Businesses get large platforms to run their apps without any need for a physical data center on their premises.

#4 Cloud Software Trends 2021

The industry has grown by over 380% in 10 years. All due to the efficiency and functionality of this software. Here are some other major trends as of 2021.

#1 Multi-cloud and hybrid solutions

It is not about one platform. Many companies implement hybrid or multi-cloud solutions, where they work with more than one provider. Often the case, it is much more effective to use several vendors than stick to one. And it is also more flexible to use hybrid solutions that combine cloud, on-premise data center, and both private and public clouds.

#2 AI engineering

Implementation of AI and machine learning is essential to working with big data and accessing valuable insights. So it is expected that AI will become an integral part of many solutions. As a result, the speed and efficiency of cloud computing will only grow.

#3 Gaming will go cloud

Amazon is already offering its cloud platform for gaming. So the gaming industry can go the same route as movies and music – streaming. It will give people completely new experiences and more opportunities.

#5 In Summary

Cloud computing is a necessity in the modern world for individuals but especially for businesses. It ensures flexibility, mobility, and business process efficiency. It allows accessing amazing features like data analytics while giving almost unlimited storage space.
