Cloud Computing

What Is Cloud Computing?

Cloud computing is a catch-all term that refers to any computing service—this includes servers, storage, databases, networking, software, analytics, and intelligence—that is hosted and delivered over the internet and on-demand.

Cloud computing architecture is built entirely using network and net-enabled systems. Individuals and businesses use cloud computing as an alternative to owning extensive computing infrastructure of their own or building/renting data centers. Cloud computing services make it possible to rent anything from access to applications to storage, from a cloud service provider.

Types of cloud computing services

There are three types of cloud service. What a career in cloud computing looks like will depend on which service you work in.

  • Software as a service (SaaS)
  • Platform as a service (PaaS)
  • Infrastructure as a service (IaaS)
  • Software as a service (SaaS)

    These are on-demand hosted services that provide access to business applications.

  • Platform as a service (PaaS)

    These are web-based services and deployment of applications in the cloud.

  • Infrastructure as a service (IaaS)

    These are virtualized computing resources over the internet and often offer storage.

What Skills Do You Need to Build a Career in Cloud Computing?

These are some of the general technical skills you’ll need to develop a career in cloud

  • Gaining a thorough understanding of the CSP marketplace is a good starting point. Familiarize yourself with cloud computing platforms, the three biggest of which are AWS, Microsoft Azure, and Google Cloud Platform.

  • Building applications in the cloud often requires knowledge of mainstream programming languages and the ability to write code to build, deploy and manage applications. Among the most well suited programming languages for a career in cloud computing are SQL, Java, JavaScript and Python.

  • APIs are widely used in modern software development both on premises and in the cloud. APIs enable different services and applications to interact with one another for data exchange. Building, linking and integrating different workloads in the cloud often requires the use of APIs. The most common types of APIs used in the cloud are REST and GraphQL.

  • One of the most widely used application services in the cloud today is the database. Cloud databases offer organizations the advantages of managed offerings with a high degree of scalability and availability.

  • Knowledge of networking basics, including how to establish connections across resources and locations, is an essential skill in the cloud.

  • In cloud computing environments, as with any other IT environment, security is an absolutely essential function.

What is the future of cloud computing?

In the last decade, cloud computing has grown exponentially. It has become such a huge part of our lives that it’s almost become unnoticeable. But, if you’ve used Google Drive, shared photos with friends or even watched a movie on Netflix this week — then you’ve been making the most of this technology.

Cloud computing is reaching the point where it is likely to account for more of enterprise tech spending than the traditional forms of delivering applications and services in-house that have been around for decades. However, use of the cloud is only likely to climb as organizations get more comfortable with the idea of their data being somewhere other than a server in the basement.

By 2030, experts predict that the sector will make an annual revenue of $1.6 trillion. Not limited to just IT, more than half of the market will consist of banking, financial services and insurance, IT and telecom services, and retail and consumer goods.

If you already have IT experience and an interest in this field, there has never been a better time to consider a job move. You might just future-proof your career.

Frequently Asked Questions

  • Are cloud computing jobs in demand?

    These are some of the most popular cloud jobs currently in demand.

    Cloud Engineer: Cloud engineers focus more on topics such as administration, application development, scaling and potentially logging tasks in the cloud. A cloud engineer’s role can look fairly different depending on the company they work for and their tasks will often overlap with other professions.

    Cloud Security Analyst: Cloud security analysts are responsible for identifying dangerous threats and vulnerabilities in cloud-native environments. They will work closely with the wider product team to keep security up-to-date and effective. Cloud security analysts often also have a background/certification in cybersecurity

    Cloud Automation Engineer:
    Cloud automation engineers build and maintain automation technology that operates on the cloud. They build systems which connect cloud services to real-world and IoT AI-based applications. They also provide troubleshooting, application release management, and documentation services.

  • Which cloud is most in demand?

    Amazon Web Services by Amazon, Azure by Microsoft, and Google Cloud Platform by Google, are the top three most in demand cloud platforms available today. Candidates looking to build a career in cloud computing should aim to complete certifications related to these platforms.

  • Is DevOps necessary for cloud computing?

    DevOps and cloud computing are two related fields in IT and many people opt to combine skills between the two when building a career in cloud computing. One reason for this is that DevOps services are often placed in the cloud.

    However, a background in DevOps is not necessary for a career in cloud computing. Though there is an overlap in skills and education the two fields also have roles that are native to each.
