Top 7 technologies that a programmer should learn in 2021


2020 was a significant year for programmers and the software development industry because of the number of breakthroughs in different areas. Digitization has risen remarkably due to the pandemic and has led to several trends of technologies in the development world.


Web and software app development is crucial for businesses today, while developers and programmers are part of the essential enterprise helping companies innovate and thrive.


1. Multi-cloud

There's no doubt that Amazon web services are the leaders in the public cloud market, taking up 32%. While Microsoft comes in second with a 20% market share, and Google Cloud holds the third position with 9% of the market share. These three companies are bound to retain their positions in 2021.


Also, Multi-Cloud initiatives are going to gather momentum as more companies move towards them. For example, although Amazon was first reluctant about this multi-cloud strategy, they have now joined the market too so that programmers can deploy their apps in multiple clouds seamlessly.


2. Blockchain

Blockchain remains a very disruptive technology and is the technology used to fuel cryptocurrencies. However, this technology has the potential to change the IT industry as a whole completely. According to PR Newswire, it is projected to reach about $30.7 billion by 2027 with a CAGR of 43%. In 2021, this technology will likely be used as the mechanism for smart contracts among several industries.


3. Data-intensive computation

The default option for data-intensive computation or distributed batch jobs some years back was Hadoop. However, according to an essay writer at assignment help, Apache Spark's emergence has led to the replacement of Hadoop for several distributed batch jobs. A significant difference between the two of them is their performance. Unlike Hadoop, Spark programs run about 10x faster on disk. It is also 100x faster than the in-memory of Hadoop. Spark was designed in a way that overcomes the faults in Hadoop, so we are likely to see a continuation of the replacement trend between Hadoop and Spark.


4. Rapid app development

As stated in a recent PR Newswire release, No-Code/Low Code market size or rapid app development is projected to have a market size in 2027 reaching up to $65.15 with a CAGR more significant than 26.1%. Several platforms such as Bubble, Microsoft, OutSystems, Power Apps, and Appian now support the no-code/low code in website development. The LCNC platforms in 2021 will become one of the most powerful trends with lots of mergers, innovations, and acquisitions.


5. Containerization

The primary technology within the cloud-native IT sector is containerization. According to Globe Newswire, Kubernetes already has an adoption rate of 48%, meaning that it is establishing itself as one of the top tools for the management and orchestration of containers. It currently leads in both the public and private cloud aspects. Also, it is crucial to note that the most prominent cloud providers such as Google, Azure, and AWS are now offering Kubernetes managed services. All of these point to a massive increase in the adoption rate of Kubernetes since it is the main technology behind the multi-cloud strategy.


6. Data analytics and science

Big data involves data collection that comes in large volumes and complexity such that the conventional data management tools can't handle these data. As more devices are connected to the web, big data continues to rise. The two significant jobs required in big data are data analyst and data scientist. The data scientist collects, organizes, and maintains a large volume of unstructured and structured data from several sources. Afterward, the data is cleaned and segregated for uniformity and accuracy purposes. Meanwhile, the data analyst analyzes the data to get actionable insights to improve the business operations.


More than half of companies are now using big data analytics for improving their business operations, making this technology a crucial one to learn in 2021.


7. Quantum computing

This technology is more of a reforming technology within the digitization era. It is likely to have an impact in several sectors. Based on a recent report by IBM, they will be debuting a Quantum Condor Processor with 1,121 qubits by 2023.


To put this into perspective, if the most advanced supercomputers are seen as 8th-grade math students or chess players, you can refer to the Quantum computers as a supergenius mathematician or a chess player capable of playing with 50 other average chess players at the same time.


Given the enormous interest and vast possibilities, we are likely to see some mind-blowing breakthroughs and discoveries in Quantum computing soon.



It is impossible to cover every area of the software industry. However, this article mentions some significant trends with technologies that can massively impact the life of a programmer. Moreover, many of these technological trends are going to continue. So it is best to start learning them.

Playing slot games on mobile devices is one of the most entertaining encounters, and everyone would love to enjoy a piece of the cake. The numerous slot games for mobile phone that exist provide the player with great convenience because they are no longer limited from where they can enjoy the game. Thanks to this flexibility, an increased number of people are adopting slots as their preferred online casino games.


Even as the slots' popularity increases, one cannot help but notice that there are some differences between the experience on Android and iOS for some games. Of course, some of the slot machines are accessible on both Android and iOS operating systems without any discrepancies. However, for most games, they would be exclusively available either for Android or iOS. That leaves you wondering which mobile operating system would best satisfy your desire to play slots?


We can look at this question from different perspectives to provide a comprehensive response:


Swift Release of Games

Slot games tend to come sooner on iOS than Android. If a particular slot is meant to be accessible on both operating systems, you will typically first find it on iOS before its Android version hits the market.


Different explanations have emerged to make sense of this trend. For one, developers find it simpler to make games for iOS because it has fewer OS models - iPads and iPhones.


On the other hand, when it comes to Android devices, the game developers have to create a respective app that works seamlessly with different Android phone models. That means making slot games available to Android users may require the developer to spend more money. Thus, iOS peers end up accessing particular games before their Android counterparts.


Android counterparts


Quality Over Quantity of Slot Game

Apple has one of the strictest rules regarding the games published on its App Store. These rules took place in 2016 and have seen thousands of outdated software that do not meet specific requirements uninstalled. The focus of these rules was to prioritize quality gaming instead of quantity, ensuring its players have access to good-quality games.


On the other hand, Google tends to have a freestyle approach to the kind of slot games published on its platform. That means you may end up having so many slot machines on Google Play Store, but most of these could be pointless. Moreover, in some cases, you may not be able to replay some of the games due to their endless glitches.


If you are looking for top-quality slot machines, iOS could be your best bet. However, if you would love to have access to a variety of slot games that may not be available elsewhere, Android would do for you.


Android Does not Have Some Crazy Restrictions

Android Does not Have Some Crazy Restrictions


Apple is notorious for occasionally implementing rules that remove thousands of applications from its App Store. That means you may have enjoyed a certain slot game just a few days ago, only for you not to find it in the marketplace. Your favorite iPhone slot could disappear any day.


On the other hand, Android users could have access to a slot machine for as long as they want. That's because Google hardly interferes with applications published on its marketplace unless when necessary. Thus, if you enjoy a given Android slot game, you can be confident that it would be around for a long time.


Smooth Gaming Experience

We have already seen that you can search for good titles on both Android and iOS. What if you access the same slot on an Android device and iPhone? Where are you likely to have a smooth gaming experience?


Generally, iPhone users have a better gaming experience than Android and encounter fewer bugs. However, even for high-end Android devices, it is possible to have a few incidences where your phone freezes in the midst of a hotly contested slot machine.


Wrap Up

To wrap up the entire comparison, both Android and iOS mobile operating systems are good for playing slots. The superiority of one OS over the other depends on what you are looking for. For instance, if you want access to a variety of games, Android would do for you. On the other hand, iOS boasts of listing only top-quality slot machines.
