Room For Improvement

Docker on Ubuntu requires UI, networking, and storage simplifications with improved documentation, security, and Kubernetes integration.
Squid Proxy enhancements should focus on GUI, AI performance, traffic management, security, integration, training, and multilingual support.
Code sharing ability exists in GitHub and other tools, but in Docker on Ubuntu, other users we are sharing with do not have options like edit and update the code.
Software Engineer at INSTITUTE OF AERONAUTICAL ENGINEERING
While Docker itself has no cost, the Docker repository and Docker Hub could improve their pricing, especially for startup companies.
Chief Technology Officer at ML Cloud LLC
It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage.
Founder at Asynka
Control of information is needed so that sensitive actions are not cached, which would violate local security laws, such as in Brazil with LGPD, and in other places around the world as well.
Analista de Segurança Senio at Optanet
With the rise of cloud systems and OpenShift, enabling such features in Squid Proxy Cache Server would be very beneficial for customers, allowing for better management.
Linux System Engineer at a tech vendor with 10,001+ employees
By default, Squid cannot see inside HTTPS traffic. It only sees the destination domain name, which poses a risk as users can bypass URL filters or download malware over encrypted connections.

Setup Cost

Enterprise users find Docker on Ubuntu cost-effective, with potential expenses mostly related to staff training and infrastructure.
Squid Proxy is cost-effective for enterprises due to open-source access, reducing costs compared to alternatives like Blue Coat.
99.9% of people will be happy with the open source version, which is open source and free.
SRE II at a tech vendor with 5,001-10,000 employees
I find the pricing for Docker on Ubuntu is not expensive because basically, it is zero.
Founder at Asynka
Docker does not have licensing.
Cloud Operations Engineer at a tech vendor with 51-200 employees
The costs are low because it is open-source software.
Works at a computer software company with 51-200 employees
I have seen a cost saving since implementing Squid Proxy Cache Server because then I don't have to really go for something such as a Blue Coat proxy.
Owner For Data Center Operations Dns Cache at Proximus S.A.
For our environment, we are using the free open source Squid Proxy Cache Server, so there is no licensing cost.

Containerization has streamlined testing workflows and reduces server resources for our builds
The best features that Docker on Ubuntu offers in my experience are ease of usability and performance. Ease of usability and performance with Docker on Ubuntu have helped me because Ubuntu is a Debian-based OS that can operate in both server and desktop modes, so when using Docker on Ubuntu on a server base, I need to install a few packages to convert the machine to GUI mode, making Docker on Ubuntu easy to use. While I think security is not a standout feature, ease of usability and performance remain the main highlights for me since it's only environment-specific and involves local testing along with monitoring only internal servers. Docker on Ubuntu has positively impacted my organization through resource savings, as for our NOC server, we are using a dedicated 30-core server with 256 GB of RAM, but with the help of Docker on Ubuntu, we can run multiple containers on the same server. In terms of resource savings, we reduced the number of servers from around 100 to 70 after using Docker on Ubuntu within our private cloud, where we have numerous servers located in multiple locations in the US.

Caching and reverse proxy have boosted performance and improved secure web and mail access
I think Squid Proxy Cache Server can be improved by having a nice front-end, one similar to Blue Coat for access management, view management, and direct configuration instead of doing it all through the CLI. It's best to have everything done through the GUI, which is what I think can improve the product. I don't want to implement third-party GUIs on Squid Proxy Cache Server. So that's what would be on my wish list—that Squid Proxy Cache Server by itself provides a GUI, which will give more confidence to users. I haven't actually used AI with Squid Proxy Cache Server, but I think it might be very interesting to have the AI capability built-in. However, I do think we need some GPU or something to boost the performance on Squid Proxy Cache Server as natively running. I think we need to add some GPU cards so that it works more natively with AI. I don't have experience using AI features yet, but I think it would be great if it could do some live scanning of the websites that are getting blocked on a daily basis and perform some sampling analysis. Especially in the case of reverse proxy, if there are any attacks happening, it would be beneficial if it scrapes through its own log files and provides some nice dashboards showing where the attacks are coming from. That would be really great to have as a handy troubleshooting tool. One more feature I would ask for is if AI can provide the best possible configuration and do a review of Squid Proxy Cache Server just to make sure that no other ports or anything by default are missed in configuration. It would also be great if the proxy server acts as a load balancer in a cluster mode that shares the cache, and the configuration is best set.
