It was the same time around last year when the government imposed a national lockdown. Last year, the world witnessed its first global pandemic which affected lives worldwide.

COVID-19 shook the entire world population with its threat to human existence. While it wasn’t a deadly virus that wiped out the entire humanity, the aftermath of the pandemic is something we will deal with in the coming years.

One of the backlash of the lockdown was unemployment.

While many companies laid off employees and cut salaries in order to keep going during the year of the lockdown, many skills remained in demand regardless of the pandemic.

That’s right! Many skills were still desired by recruiters which is a testimony of their importance in the professional world.

Today, let’s take a look at some of the methodological skills that defied COVID-19 Impact and kept growing even during the time of crisis.


PaaS or Platform as a service is a cloud computing service that allows users to develop, run and maintain applications without the hassle and complexities of the infrastructure that is required for developing an application.

Similar to Faas (Function as a service), PaaS charges the users only for the compute, network and storage resources used. It is delivered via hybrid, public or private clouds.

In a public cloud setting, the deployment of the software is taken care of by the customer while the IT components such as servers, storage, operating systems, networks and databases are all taken care of by the cloud provider.

PaaS as a skill is very crucial for a software engineer. The recruiter searches for Naukri shows an increase of 50% for the keyword PaaS from February 2020 to February 2021.

This indicates how important PaaS is as a skill and can help in increasing the chances of landing a great job.

And ofcourse, it definitely has defied COVID-19 impact.


Microservices is an architecture that structures an application as a collection of loosely coupled services that are:

  1. Owned by a small team
  2. Highly maintainable and testable
  3. Organized around business capabilities
  4. Independently deployable
  5. Microservices makes the delivery of complex applications possible.
  6. It also enables a company to evolve their technology stack.

From February 2020 to February 2021, the skill term of Microservices has seen an 81% increase in the recruiter’s search on Naukri.

Another skill that has defied the COVID-19 impact.


IaaS or Infrastructure as a service is a cloud computing solution that offers virtualized computing resources.

Similar to PaaS in this post, IaaS provides resources related with IT infrastructures via virtual machines over the internet.

The cloud provider generally in a IaaS setting, will provide IT infrastructure such as storage, server and networking resources via virtual access to the customer or user.

It makes the workloads cost efficient, faster and easier for organizations. Hosting Infrastructure components as cloud providers helps the user save a lot of money on setting up infrastructure themselves.

According to the recruiter’s search numbers on Naukri, IaaS as a skill term has seen an increase of 47% from February 2020 to February 2021.

Data Lake

Data lake is a centralized repository where data is stored in raw format. All types of data including structured as well as unstructured can be stored in Data lake at any scale.

Data can be stored on Data lake without the need of running any analytics or structuring the data. Surveys show that companies that adopt Data lake see a 9% growth in their revenue.

This makes Data lake very popular among companies and also as a skill for engineers.

Data lake saw a rise of whopping 145% from February 2020 to February 2021 in recruiter searches on Naukri.

Data lake clearly defied the COVID-19 impact by miles!


CI/CD is also referred to Continuous Integration and Continuous Delivery or Deployment which is nothing but a method that helps deliver apps to customers by bringing in automation into the stages of development.

CI/CD enforces automated deployment, building and testing of applications.

Modern DevOps rely heavily on CI/CD as they practice continuous deployment, integration, testing and monitoring throughout the development cycle of an application.

Jerkins is one of the common open source tools for CI/CD. It’s designed to handle anything from a simple CI server to a complete CD hub.

Recruiter searches for CI/CD skill increased by 100% from February 2020 to February 2021 on Naukri.

Another skill that defied COVID-19 impact and grew regardless of the pandemic.

ETL Testing

ETL is a process that uploads data into a single repository by extracting data from source systems and transforming information into a data type.

While ETL Testing refers to the verification, validation and qualification of data without any duplicative records or data loss.

The ETL testing is done to ensure that the data has been loaded from source to destination.

Recruiter search on Naukri saw an increase of 80% from February 2020 to February 2021.

ETL Testing is another skill term that is used by recruiters to find credible software engineers. The numbers only prove that this is again one of the skills that have defied the COVID-19 impact.

Data Modeling

Data modeling is the creation of a data model for the stored data in a database. The created data model is a conceptual representation of data rules, objects and association between different objects.

Data modeling helps in visualizing data and enforces business rules. It organizes data semantics, data description and consistency straints of data.

Data modeling emphasizes on how data should be organized and what data is needed instead of what operations will be running on the data.

According to recruiter search data, Data modeling increased by 75% from February 2020 to February 2021 as a skill term on Naukri indicating how it defied the COVID-19 impact.

Data Warehouse

Data warehouse in computing is a component of business intelligence which is used for reporting and data analysis.

Storing the current and historical data in one place, Data warehouses are the central repositories of integrated data from disparate sources. This data is used for creating analytical reports.

Operational teams such as marketing or sales upload data from their systems into the data warehouse which may require to go through data cleansing to ensure the quality of the data before the data warehouse is ready for reporting.

Data Warehouse saw an increase of 67% in terms of recruiter search on Naukri.

Such growth only hints at the fact that as a skill it defied the COVID-19 impact.

Since the beginning of the pandemic, the discussed skills in this post have only grown in demand.

This indicates that these skills are highly desirable in the IT industry and also should be considered for adding to one’s repertoire to increase the chance of landing better jobs.

Apart from these methodologies, many frameworks, platforms, programming scripting languages and tools have emerged victorious as jobs related to them have increased, defying the influence of COVID-19.

These skills are the future of IT and their demand is likely to grow more in the coming years.
