Is a question posed to me on a daily basis from clients, candidates and colleagues.
Firstly it really depends on who is asking, why and in what location but on the whole there are definitely new trends within the market and clear to see in 2017. Of all the vacancies I recruit for the majority are still Java and Microsoft.Net based as Java is a firm favorite for business applications, used at most financial services institutions for back end systems, portals, trading systems, market engines and online banking, and Microsoft.Net with its flexibility and usability has made it a hit among businesses and developers worldwide, making the two languages ever popular in the market.
Not only candidates but also clients I work with are keen to use the "latest" software tools and in the past 6 months it is very clear to see which languages and which tools are in real demand.
Node.js - lightweight, fast and modern way to execute code, Groupon rebuilt its entire web layer with Node.js and other well-known brands (PayPal, LinkedIn, Uber)
AWS - with the rise in cloud computing, Amazon Web Services now leads the pack in terms of market share and quality of service in their core offerings they support top Fortune 500, commercial SaaS providers and tech giants (Expedia, Unilever, Pinterest)
These are only 3 of a huge amount of up and coming technical trends and in fact will not give a clear picture of the whole market, but from a perspective of a technical recruiter and from current vacancies there is an inclination that React, Node and AWS are ever present and in such high demand in the market.
So if you are out there looking for work at the moment and you have experience of these technologies make sure your CV screams it! If you are a client recruiting for these technologies, understand, you are not the only one, so if you find someone acts fast otherwise they will be gone!
