How do companies actually use Docker?

Businesses want Docker. Docker is becoming more and more close to start-ups as well as with big economic groups even though it is just a very new tool.
Unlike what we often think, businesses need not touch the promising land of "DevOps transformation" to start using Docker. They do not need a "small service" model or a fleet of talented engineers. In fact, Docker is very suitable for long-term businesses who work on IT transformation and it can really help improve DevOps quickly and effectively.
The hybrid cloud model is the result of nearly half of businesses, most of which are in the process of receiving the DevOps toolkit. Businesses are hiring consultants for cloud computing, consolidating data centers, breaking down barriers between engineering teams, and moving new applications to AWS or to public clouds. other.

Understand hybrid cloud computing.

Even though the hybrid cloud promises to provide proactive benefits, its security management and scalability across multiple complex systems is a challenge for engineers. Intrinsic dependence, complex networks and countless giant data groups are a major burden for the vast majority of applications of many businesses.
This is the key point that Docker is increasingly used by many businesses. The biggest reason businesses want to use Docker is because it helps businesses move between systems while moving applications and eliminating manual operations. Docker will cause information exchange concerns to be limited because the dependencies of these applications are already built into the information boxes.
Therefore, applications that have tested very well in the public cloud environment will operate so completely in a production environment in private cloud computing. In addition, these applications can also run during production on any public cloud platform.

Promote the culture of DevOps.

This is good news for businesses seeking a catalyst for DevOps's cultural transformation. DevOps' shifting step promises less resource usage, as well as faster movement. Allowing developers to provide Docker containers, test them and move to the production stage in minutes, is very cost-effective, while eliminating the most dangerous enemies for players. development, it is a system of manual manipulations.
Docker is also perfect for developing businesses because they usually follow only one vendor. Standardizing containers will make moving between clouds operated by different companies easier and more convenient.

Check the security system

However, it is impossible not to mention the shortcomings that businesses will encounter when using Docker. In fact, businesses are very concerned about Docker's security in hybrid environments. In addition, the containers may be similar to those simulated, however, they may have huge differences in the systems, in the acquisition and in the end. In addition, many businesses also encounter very strict management procedures that are really carefully monitored. To put it more simply, there is no one sorting tool that can manage security through a multitude of different Docker platforms. Most tools on the market today do not have temporary examples in the public cloud, let alone separate devices.
In the event of a security risk, the Docker container will have to mobilize manual security. Docker allows you to improve the image but the developers will have to make sure that the images only work in each container.
For businesses that require a multi-user environment to isolate environments from other customers, Docker is definitely not an optimal choice. The reason is because you are running on that kernel, which is not synonymous with splitting VMs under supervision. Businesses with state-of-the-art devices will feel that Docker containers create challenges to transport data at the right time and in the right place.
Docker is probably the choice for businesses that have challenges with hybrid clouds. But it is also a completely new technology with lots of arrangements and security devices that businesses need in the manufacturing process. This is probably the time for businesses to really learn about Docker, making an effort to run this application in a hybrid environment, to find out its shortcomings.
Docker storage box is quite new in Vietnam, but this phenomenon has become a trend and a huge source of technology.
