platforms

In the Platforms chapter, too, the preselection has been expanded to include the additions from the 2019 free text specifications. As with frameworks and libraries, there is a wide variety of platforms with very different use cases. Once again there is a wide scope for interpretation as to whether a technology would now be classified as a platform or a framework. However, based on the feedback, the divisions used here seem to be well received by the participants.

Important: There are platforms on which applications can run relatively freely regardless of programming languages or frameworks - for example, Linux, AWS, or Kubernetes/Docker. But there are also platforms for which development is software-specific. These include Sharepoint or SAP, for example - in other words, platforms that are very strongly coupled to development.

Platforms developers use

• As in the previous year, the operating systems Linux, Windows, macOS, Android and iOS are in the top 10. Containers are also well represented with Docker and Kubernetes as well as the newcomer OpenShift. The latter solution originates with RedHat and was designed as an enterprise solution around Kubernetes and containers.
• Based on last year's feedback Microsoft Teams was included in the preselection and jumped straight to position 7 behind Slack. Whether attendees perceive this as a development platform or a separate work tool remains to be seen.
• Raspberry Pi is still in the top 10 and Arduino also makes it into the top 20. It is important to keep in mind that these are platforms that are actively used by developers in software projects - a very important realization that is probably not known to many outside the field. Similarly, game consoles such as Playstation and XBox are also used by a significant number of developers.
• The adjusted preselection has also led to the fact that hardly any new free text answers were mentioned more than once in 2019. Only Jira is a new addition. Intuitively, some may see this differently and therefore miss various entries, but the swiss developer survey is based on international statistics and the responses from the previous year.

Platforms developers would like to use

This is about platforms that developers would like to use, but are not currently using. What is meant here is personal preference and not whether they also recommend these for companies to introduce.

• Containers are again at the top of the list, directly followed by Linux. It is important to know that containers are basically simple processes that are given their own environment by features in the Linux kernel without being virtualized. The advantage is that processes can be started extremely quickly and leanly while still retaining the advantages of encapsulation as with VMs. So you can easily start hundreds of containers on one server, which would hardly be possible with virtual machines. In other words, when we talk about containers, we are generally talking about Linux processes.
• Cloud services are also central - from AWS to Azure to Google Cloud Platform. When we talk about serverless, we usually mean a service from one of the three major providers.
• OpenShift is not only at the top of the usage list in the previous chapter, but also rises to the same level here.

Platforms developers like

In general, coders were more eager filling in here, more than the increased number of participants would lead one to expect. Nevertheless, the top 10 in particular has hardly changed.

• The newcomers OpenShift and Microsoft Teams are also equally high here, whereby OpenShift in particular is seen with a lot of goodwill by its users. So there are definitely corporate enterprise solutions that are popular.
• SharePoint is hardly mentioned in comparison to the distribution of the solution - in contrast to Wordpress, for example, which is accepted by a much larger number of its developers.

Platforms developers don't like

As in the previous year, Windows, Sharepoint and Wordpress meet with little approval. But iOS is also at the top of the "I don't like it" list.  For comparison, we add the previous list of platforms that developers like. That provides some additional context in the real-world ranking.

• Interestingly, the newcomer Microsoft Teams also rises comparatively high here. However, this position is somewhat relativized by the relatively large number of developers who like it.
• The clear losers are SharePoint and SAP: both platforms collect a lot of mentions for "I don't like it" and hardly any for "I like it".
• Winners in the "I like" vs. "I don't like" factor, on the other hand, are Raspberry Pi, SpringBoot, Linux, Docker, Android, Kubernetes and AWS.

Platforms developers want to adopt

We turn to platforms that developers recommend for implementation: This assessment has a certain closeness to the "I like it" theme, but is not congruent - accordingly, this list is again presented for comparison. 

Once again participants filled in very eagerly, and, without wanting to bore, Linux and containers (Kubernetes/Docker) were listed at the top with strong growth.

Also important to mention is SpringBoot, which for historical reasons is listed under Platform and not Framework. However, it might be better to move this technology to the Frameworks area in 2021. At the moment, it looks as if it could replace Java EE or Spring in particular as a framework in the Java area.

Platforms developers want to replace

As in the previous year, a comparatively large number of developers recommend replacing Windows, SharePoint, Wordpress and SAP. Windows Phone has also disappeared completely - probably because it has left the everyday working lives of most coders just as it has left the lives of any users.

Surprising is the frequent mention of OpenShift: 21 developers want to replace it, while 28 want to introduce it - only a small number of mentions, but perhaps still a topic to discuss with your development team.

Platforms developers want to keep

Finally, the list of platforms to be retained - this also in direct comparison with the platforms to be replaced. It is exciting to see which ones show a strong gradient and where the camps balance each other out.

• From this perspective, Windows on desktop and server slip back into the positive. Even though many developers would like to do away with this system, there are a few more who want to continue using it.
• It looks even more positive for Linux, which is only mentioned 4 times as "to replace" and 295 times as "to keep". The statement could not be clearer. The situation is similar for Android, although the gap is not quite as wide there.
• The reverse is true for SharePoint and SAP, which is no surprise based on the previous statistics.
• In the CMS area, more developers generally want to replace the solutions than keep them. Only Magnolia CMS seems to balance out here, so that the same number of developers want to keep it as want to replace it.
• Why Adobe Experience Manager and the 10'000 other CMS are not listed here has purely to do with their usage statistics. De facto there are only a small number of companies in Switzerland using AEM. In comparison, TYPO3 as well as Drupal are still leading in the enterprise sector. Just like the global number 1: Wordpress.
