An information technology practitioner or one aspiring to become one should seriously learn about the Public Cloud market. According to Synergy Research Group, the Cloud market is over a $17 billion market (Synergy Research Group report) that continues to grow every year. The three biggest companies in the public cloud market are Amazon (Amazon Web Services), Microsoft (Azure), and Google (Google Cloud Platform). But before I get ahead of myself, let me describe the cloud. Microsoft has a great definition and defines cloud computing as “the delivery of computing services-servers, storage, databases, networking, software, analytics, intelligence and more-over the Internet (“the cloud”) to offer innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.” Cloud computing is usually described based on one of two things, the deployment model or the service the cloud is offering. The deployment models are Public, Private, Hybrid, and Community Cloud and the service cloud models are Software-as-a-service (SaaS), Platform-as-a-service (PaaS), and Infrastructure-as-a-service (IaaS). For more details on the deployment models visit Amazon and the service models here.


Cloud computing has been embraced by just about every industry due to reduced IT costs, security, scalability, business continuity, collaboration efficiency, and flexibility of work sites. Amazon was the first company to the market in 2006 and currently holds the market share. Microsoft followed in 2010 and then Google in 2013. According to Gartner, AWS remains the leader with 51.8% of the total market with Azure coming in second with 13.3%. However, keep an eye on Azure as its year-on-year growth in adoption is 35% compared to 15% with AWS.


Ease of Entry

Companies such as Amazon, Microsoft, and Google couldn’t have made it easier for you to learn about their platforms. They each offer complete access to their platforms for “free” (free comes in the form of credits that are good for a number of hours of use per month or for the year) and provide excellent documentation on their websites to get you up to speed. Additionally, there are several resources on YouTube and on training sites such as In conclusion, this market is HOT and there has never been a time when practitioners have been given free access to a billion dollar commodity for training and all the documentation to learn. They are daring you to learn! Accept the challenge and rise to greater heights in your career.
