Developers are also taking advantage of multi-cloud strategies , with two-thirds now running Kubernetes in multiple clouds .

Based on a survey of 776 qualified software development and IT professionals , the key benefits indicated include : improved resource utilisation and spend ( 59 %), easier application upgrades ( 49 %) and slicker cloud migration ( 42 %).

The report also shows that security is still a top concern among nearly all respondents ( 99 %), and more than half ( 51 %) recognise that there is a lack of internal experience and expertise to deploy and manage Kubernetes .

“ The last few years have cemented people ’ s desires to use Kubernetes as the standard layer on-top of infrastructure , across private and public cloud , often both . Usage has moved beyond the early users and more into the mainstream ”, said Michael Cote , Staff Technologist at VMware .

“ Although there ’ s still a lot of build out to come , you ’ d be hard pressed to find people who aren ’ t putting together plans to deploy Kubernetes , let alone who already have as the survey shows . This mainstreaming is growing the need for Kubernetes management tools and even distro , especially when it comes to security and supporting developer experience . And , indeed , almost 100 % of people in this survey are interested in finding and paying for tools that help them get the full benefits out of the Kubernetes lifestyle ”.

Further report findings include :

Kubernetes has crossed the chasm :

• One of the clearest signs that Kubernetes is mainstreaming is the rapid growth in the number of clusters being deployed : 29 % of organisations have more than 50 clusters and almost half ( 48 %) expect the number of Kubernetes clusters they operate to grow by more than 50 %.

The factors that have contributed to the increased adoption include :

• Improving software development : 62 % chose increasing flexibility of applications and 54 % selected better developer efficiency as key reasons .

• Cloud adoption : 59 % of respondents chose improving cloud utilisation and 46 % picked reducing cost of cloud as important factors in adoption .

• Operator efficiency : More than a third ( 37 %) said the need to improve operator efficiency was a selection factor .

Multi-cloud predominates :

One of the main reasons that organisations are adopting Kubernetes is because it delivers clear benefits for rapidly expanding cloud operations . There is an accelerating trend away from on-premises and singlecloud Kubernetes deployments in favour of hybrid and multi-cloud :

• Respondents whose Kubernetes footprint is mostly for development favour onpremises ( 62 %) or a single public cloud vendor ( 42 %).

• By comparison , those whose Kubernetes footprint is geared toward production prefer multiple public cloud vendors ( 52 %) followed by on-premises ( 47 %) and a single public cloud vendor ( 42 %). p
