2019 Cloud Market Tendencies and Career
The worldwide infrastructure as a service (IaaS) market grew 31.3% in 2018 to total $32.4 billion, up from $24.7 billion in 2017, according to Gartner report and the numbers can be seen in the table below.

By the named companies, IBM reached the last 5th position. IBM was reference in the past as synonym of innovation in hardware and software but unfortunately the last decade has not being good for it in a general way. Even Warren Buffett investment on it did not bring an advantage to the company.
The Chinese Alibaba is the unique company that is not American in the top 5 list. China weight of citation on International Journals increased almost 5 times since 2000 and in 2015 China initiated the program Made in China (MIC) 2025 which strives to secure China’s position as a global powerhouse in high-tech industrie. It seems that robotics, 5G and Huawei are only some appetisers to what can come in the future and Google already felt the impact.
When the comparison is between Amazon and Microsoft there are some few singularities. There is no doubt that Amazon earned more than 3 times the revenue of Microsoft but in terms of market share I believe that comes the major contribution from this post.
Microsoft increased 60.9% or almost 3 times more than Amazon. Only Alibaba with 92.6% reached the highest value on growth. It seems that aggregated value associated to its infrastructure is working well.
In terms of career, it is undeniable that Amazon has more positions available but at the end the companies offer almost the same services with different names, when the subject is infrastructure. It seems that would be a good advice to keep an eye on Microsoft and in terms of future, it would be a wise decision to research more about Alibaba.
