Technology has been evolving at a pace that the annual predictions about trends may seem to be outdated before they go live as a published blog post or article. The technology when evolves allows progress and change which accelerates the rate of change.

The careers that are based on technologies do not change at the same speed, rather they evolve and the IT professional know that their role is not going to be the same. In the current time, an IT professional will be found constantly learning one or the other thing not because of desire but may be out of necessity.

So it is necessary to keep your eyes on the future, to know the skills that you need to learn and the types of jobs you want to work in. Here are five technology trends for 2020 which will be acquired in the market:

1) ARTIFICIAL INTELLIGENCE

2) MACHINE LEARNING

3) INTERNET OF THINGS

4) DEVOPS

5) COGNITIVE EDGE COMPUTING

6) ANGULAR AND REACT AND VUE

So let us discuss the various technologies:

1. ARTIFICIAL INTELLIGENCE :

Artificial Intelligence or AI has been existing for a long time and also has received a lot of buzz in recent years. AI refers to computer systems that mimic human intelligence and performs tasks like recognition of images, speech and decision making. AI can do tasks faster and accurately than humans. AI is used in services like navigation app, scheduling trains, improving energy efficiency, streaming services, smart devices, and access business risks; predict maintenance and many other money-saving tasks.

AI is a part of automation. Automation is developing jobs and reducing a lot of human effort and costs in the technical field. To name a few job developments, testing, programming, support and maintenance jobs will be created.

2. MACHINE LEARNING

Machine Learning is a subset of AI. The computers are programmed to learn to do something. They are given sets of data and they predict certain aspects of business by discovering patterns in the given sets of data. The types of learning can be classified as: supervised and unsupervised. While ML is a subset of AI, we also have subsets in the domain of ML which include neural networks, Natural Language Processing (NLP) and Deep Learning. Each subset offers an opportunity for specializing in a career field.

Machine Learning is creating a huge demand for skilled professionals as it is rapidly deployed in all kinds of industries. Machine Learning jobs rank among top trending jobs on LinkedIn. Machine learning applications are used for data analytics, data mining. And if seen from the consumer end, ML powers web search results, real-time ads to name a few.

3) INTERNET OF THINGS:

Many things that are built with Wifi connectivity which means they can be connected to each other is called as Internet of Things or IoT. IoT is the future and has already enabled devices, home appliances and much more to be connected to and exchange data over the internet. We can say we are only at the beginning stage of IoT. As consumers, we are already using and benefitting from IoT. For eg: When we leave home without a locking door we can lock it remotely or the Fitbit that tracks our fitness. The IoT can enable better safety, efficiency, and decision making for business as data is collected and analyzed. It can enable predictive maintenance, improved customer service and offer benefits we haven’t even imagined yet.

Despite this benefit in the development and adoption of IoT, experts say there are not enough IT professionals trained for IoT jobs. The skills that you need to develop are IoT security, Cloud computing knowledge to name a few. To sum up, it’s the Internet of Things and there are plenty of skills that are needed.

4) DEVOPS:

Image Source: Dzone.com

The DevOps started to merge in the IT industry somewhere between 2007 and 2008 when IT operations and software development section spoke about the level of dysfunction in the industry. Developers and IT professionals had separate objectives, key performance indicators by which they were judged. This resulted in siloed teams and things worsened in IT prospects. So the two sections combined together for conversation and the team got this theme which we are discussing now.

DevOps is a process in which a set of tools are implemented to automate the process between software development and IT team, to build, test and release software faster and more reliable. The concept of DevOps is set up on building a culture of collaboration between teams that historically functioned in relative silos. The benefits include faster software releases, the ability to solve critical issues quickly and better manageable unplanned work.

5) EDGE COMPUTING:

Cloud computing has become mainstream in today’s world. The players of cloud computing are AWS (Amazon Web Services), Microsoft Azure and Google Cloud dominating the market. The businesses are migrating to cloud station as the adoption of cloud computing is growing. But it is not an emerging technology.

We have realized the shortcomings of cloud computing in some situations as the quantity of data we are dealing with tends to increase. In order to solve the problems to bypass the latency caused by cloud computing and getting data to a data center for processing, edge computing is designed to help solve some of the problems. Edge computing can exist “on the edge”, somewhere close to the point where computing needs to happen. Thus edge computing is used to process time-sensitive data in remote locations with limited or no connectivity to a centralized location. In this situation, edge computing act like mini datacenters. Edge computing will be increasing as the use of Internet of Things (IoT) devices increases. Thus this will be creating various jobs in the market basically for software engineers.

6) ANGULAR AND REACT AND VUE:

It has been quite a few years now when web applications have captured the market completely. And hence started the battle of the best JavaScript framework. The Tech Giants have come up with a lot of Revolutionary JavaScript frameworks. However, deciding the best Javascript framework can be a pretty tedious task. ‘Angular vs React vs Vue’ is the current trending topic in 2020–2021. These frameworks come from a lineage of two powerful competitors — Google and Facebook. Among these three frameworks, React has already got a huge appreciation and therefore establishment in the industry. The newer flavor of Angular, however, is the most talked-about subject among the Webster.

Frameworks and libraries are shipped with different license agreements. Some vendors publish licenses that allow customization as per requirements and provide flexibility. Products with these categories of licenses are known as open-source products. The other category of licenses does not allow manipulations for designing of commercial applications without attributions.

React outweigh Angular and Vue. React observes higher downloads among the world websters. Vue closely follows React and is gaining rapid momentum, but Angular has remained the same for the past few years. React goes high on preference for its easier CSS markup.

Angular is preferred for large corporations, for its solid set of tools and quality community and the paid support. The Angular framework is considered more difficult for beginners as the learning curve is steep. React is relatively a mature product that is popular and appreciated among developers. The two key features of the product are immense flexibility and easy integration. Also, it is the most versatile option among the three. Vue has been existing for several years now but is relatively a newcomer. Some of the Asian companies have switched to Vue because of its quality. It is suited for fast-paced growth. Needless to say, all these three frameworks are perfectly suitable for mobile development in 2020.

So, even though technologies are emerging around us, these technologies are going to offer a promising career for the upcoming period. Right now these technologies are suffering a shortage of skilled employees which means it’s the right time for you to choose the one to get trained and develop your career.

VPC A can talk to VPC B. VPC B can talk to VPC C.

Does it mean VPC A can talk to VPC C as well ?

SR Cloud Engineering

No, no transitive connection in VPC peering. You have to create peering between A & C too if you need connectivity.

The prospect is always good for any new technology. However, as you would have realised every technology has its pros and cons. and this is still situational. So it is important to weigh this against the situation and specifics of your question.

What are the main differences between cloud engineer and DevOps engineer?

Rangarajan

3+ decades of work experience with 20 yrs into IT Infrastructure services- both traditional & Cloud

There is nothing called a cloud engineer. You have to add the qualifier statement like Cloud Dev OPs, Cloud SysOPs, Cloud Solution Architect, etc.. It gives an idea of what the person does using the cloud technology.

Hi,

If you need the permanent public IP address, for instance (node), you have to choose the elastic IP address and attach to the case. It's useful for DNS mapping also to the IP address (name to IP).

It's not true. If you are talking about cloud services, AWS is #1, followed by MS Azure and then Google Cloud. Oracle is predominantly an Enterprise-class Database Management solutions provider. They have cloud services too but not famous yet.

Is AWS lambda free?

Imrankhan Patan

Experienced IT professional

No, it's not free, it's charged per execution. There are free limits based on your account type, but once you cross those limits, it's chargeable in real business scenarios, it's chargeable as per total executions per month.
