On multiple cloud platforms to run applications it has become a major driving force in the use of container technology, bring benefit far more than the previous, as developers enhance the efficiency of and support for micro-services.
In the 2018 edition of the "Annual survey container technology uses", the number of users Portworx interviews from 250 in 2017 increased to 424 in 2018. More mature container from the user's perspective: security, data management and cloudy is the greatest challenge currently facing, and permanent storage is no longer the biggest problem.
In the past few years we have seen, it is often said lock a single cloud provider is a disadvantage, but do not actually use multiple cloud service providers. Survey shows that those who claim to use it because the respondents cloudy container technology, only 26% of respondents actually use the container on multiple cloud platforms. Compared with them, the developers emphasize efficiency of the respondents in the 40% of the container is running on multiple cloud platforms. Only 12% of respondents believe that micro-services architecture to promote the use of container technology, which compared with 32% in 2017 of a decline. 2018, more than 25% of respondents believe that the main application container is to save infrastructure costs.
Compared with the container, server-oriented point of view is still more popular. Developers believe that if you do not maintain the server, you can achieve higher productivity, while reducing expenditures cloud infrastructure. This group of container users tend to think that "no server technology makes obsolete vessels", 41% of respondents agree with this view, only 29% of respondents said they did not agree.
However, according to The New Stack recent survey, many respondents may not be aware of portability between platforms is no server cloudy concept biggest problem. If the problem can not be solved, then we need to continue to use the vessel turned back, provided that the current user no longer considered Cloudy container is one of the biggest challenges.
More than half of container users pointed out that in the process of deploying the container, security is one of the biggest challenges they face. This last case is considered permanent storage point of view the biggest challenge in stark contrast. Greater data management challenges over concerns for permanent storage.
Gou Rao Portworx chief technology officer believed to store and protect data issues have been resolved to get started, so that developers can focus on the backup / recovery, migration and replication data management and other issues. Based on the storage container from the point of view of the connector, EMC's RexRay NetApp or all of Trident scheduler exists the problem of integration, because they are built on the underlying storage system data management functions.
Security is the biggest challenge currently facing the container during deployment. Security concerns and more serious compared to previous surveys, because respondents are gradually putting more applications deployed in the container.
This again comes to storage. Concerns about persistent storage is gradually disappearing, but in fact the challenge has gradually increased. When asked about the process vessel running state of the specific challenges, in addition to the lack of tools, each of the other challenges than the rise in 2017 have taken place. Rao believes that the reason some people think the problem has been solved permanently stored, and because the industry has achieved some results in the permanent storage of standardized interfaces, first Docker volume drive, followed by a container storage interface recently. Although we have been able to take advantage of the container running state services, but the operation was still not simple.
