Time-saving deployment with seamless virtualization for diverse environments
I used Docker to Dockerize Java code. We had a code base, and I needed to create a Docker image from it so that it could be deployed. At the time, we used Docker Compose, which is somewhat similar to Kubernetes Docker allows virtualization at a higher level without the need for a host machine.…

Reverse proxy and security controls have provided flexible access and strong TLS protection
I have utilized NGINX Ingress Controller SSL and TLS termination feature. We have done extensive SSL offloading on NGINX Ingress Controller and made the TLS configurations to match security requirements, allowing certain TLS versions while disabling others such as 1.0, 1.1, and 1.2, and allowing 1.3. The choice depends upon the application requirement. The reverse proxy capabilities of NGINX Ingress Controller in managing distributed applications is central to its main concept. We need to configure it to allow the server to access the outside world and the internet. That is achievable, and we can install and configure NGINX Ingress Controller as a reverse proxy. It can work as a load balancer, but the main part is NGINX Ingress Controller's role as a reverse proxy. If any applications need to be accessed through the proxy to the outside world, then NGINX Ingress Controller is a good product for you. I employ the IP whitelisting feature in NGINX Ingress Controller, which helps secure my application environment. In IP whitelisting, there are several options available. You can determine which IPs to block, for example, if you do not want to give access to specific regions. You can find the list of IP addresses registered in those regions and blacklist them. There is also the web application firewall (WAF) where you can create policies to identify the type of traffic trying to access the application.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Docker's containerization property is its main selling point."
"The most valuable feature of Docker is the dedicated QA environment for connecting the team members. Additionally, there are many core features available and it is highly secure when we are imaging a client's server."
"The most valuable features of Docker are its security, detailed documentation, and ease of use, and the Docker Swarm is not as complex as Kubernetes."
"Kubernetes is the primary container orchestration tool I use with this solution. Docker provides a complete solution for deploying and managing workloads across multiple nodes. Container orchestration has significantly impacted my workload by automating tasks and streamlining operations. The availability of systems like Kubernetes is crucial for planning and managing complete clusters and computing environments. Every client's needs are different, and not one solution fits all."
"There are ways of using Docker where you have absolutely no dependencies on the environment that you work in. This allows us to deploy Docker anywhere anytime and this has been most valuable."
"The most valuable feature of Docker is that it revolutionized virtualization by providing a new approach with containers that completely nullified the time it used to take to deploy applications on virtual servers, resulting in deployment times that can be as quick as milliseconds, unless it is a heavy application, such as Java. Additionally, resource utilization has greatly improved with Docker, allowing for more resources to be allocated to other tasks. These are a few key features that make Docker a preferred choice."
"I think the best feature is to replicate anything in our local machine using a simple command."
"Docker creates lightweight applications that are easy to manage and scale."
"The main benefit is that it is better in performance, provides security with App Protect and WAF and DDoS, and delivers high performance and high stability."
"However, the response, throughput, and solid performance we receive after implementation are often worth it."
"From my experience, I think the main benefit NGINX Ingress Controller provides to the end user is the reliability of NGINX Ingress Controller itself."
"NGINX Ingress Controller has positively impacted my organization by helping us with exposing our applications and managing security and auto-scaling."
 

Cons

"There may not be much room for improvement with Docker as it has greatly evolved. However, one area that could be improved upon is the documentation on their website which was once easy to follow but has become quite terrible with numerous versions being released. As an example, the installation process for Docker now requires more than just a one-line command, causing inconvenience. Additionally, based on my experience as a college instructor, teaching students to install Docker was a difficult task due to the lack of straightforward and easy-to-follow documentation. Docker should focus on improving their documentation to make it more user-friendly for all."
"I would like to see better management layers."
"I think Docker can improve as it relates to overall stability."
"One of the challenges I face with Docker is debugging containers within the infrastructure. It can be tricky to debug applications inside containers, which is a common issue among developers. If easier tools or methods were available to debug applications within Docker containers, it would be very beneficial."
"The volumes for persistent storage could be more user friendly right out of the box."
"I would like to see a more UI-based tool so that students can easily understand it rather than memorizing all of the Docker commands."
"We'd like knowledge transfer to be easier."
"The product does not have an extensive documentation. The tool does not have good scenarios. We have to go through the GitHub repository and investigate similar scenarios. Also, if you are copying multiple things, then you can jeopardize the copy number. The copying aspect also lacks a UI part. We also need to limit the memory."
"Most customers are satisfied with the reverse proxy capability, but the main issue is that the Ingress NGINX, the one that is most widely used, will be deprecated this month."
"However, there is still a major limitation in GUI capability to manage and observe."
"Nowadays, the quality has been degrading, and I do not expect the same level of service."
 

Pricing and Cost Advice

"The solution offers an open-source version that is free and includes a lot of functionality."
"Since Docker is an open-source solution, it is free of cost."
"The offering and service are quite free."
"There is a license needed to use Docker."
"Docker's price is good."
"The current cost for us is nothing as an open source."
"Regarding pricing, we primarily use AWS for our deployments since we have funding for it. We don't spend much on Docker-specific services, just the containerization product. Docker Hub isn't particularly expensive either, so overall, the pricing is pretty reasonable."
"Docker is a free open-source solution."
