ROI

Sentiment score
4.6
Companies achieve cost and time savings with Docker on Ubuntu via faster builds, deployments, and reduced storage and resource needs.
Sentiment score
6.2
PostgreSQL on Ubuntu reduces costs by 40-70% with fewer staff needed, easy demos, data consistency, and enhanced performance.
The main return is time-saving, as it provides less setup time, fewer errors, and improved developer productivity.
DevOps at Chill Flow
You need some type of operating system and a container engine, and these two are best in class.
Cloud Ops Lead at a tech vendor with 10,001+ employees
There is a pipeline for it, and the time saving occurs because whenever a developer pushes anything, that goes into the Docker container and builds it.
Senior Dev Ops Engineer at 11 East Capital
We cut database infrastructure costs by roughly sixty to seventy percent by moving away from managed databases to using hosted PostgreSQL on Ubuntu VPS instances.
CEO at Grant Corporation
Since there are no upfront licensing fees, the ROI is increased with a scalable system without exponential cost growth.
Senior Software Developer at hireHQ
Think about if you are in a different geographic location and your cluster is hosted in two different geographic locations, maybe one in South Pacific and one in Western Europe. In both cases, if write transactions are happening, this is a good way to basically order the transactions so that the eventual data consistency is there.

6.0
Docker on Ubuntu provides scalable, flexible integration with Kubernetes, suitable for diverse applications and seamless CI pipeline integration.
Sentiment score
6.6
PostgreSQL on Ubuntu offers excellent scalability and performance, though challenges exist with horizontal scaling and native cloud elasticity.
In some cases, Docker on Ubuntu is not enough for all the complexity of the applications, and I have to go to the next level with Kubernetes.
Founder at Asynka
Ubuntu is very stable as an operating system, and Docker scales well when used properly across projects and environments.
DevOps at Chill Flow
Using Docker on Ubuntu together is a common configuration, and you can deploy it directly on server hardware using virtual machines or in the cloud, scaling however you wish.
Cloud Ops Lead at a tech vendor with 10,001+ employees
Read scaling is supported natively; PostgreSQL enables statement replication, allowing us to spin up read replicas on Ubuntu to distribute read-heavy workloads, which is fantastic.
CEO at Grant Corporation
The scalability of PostgreSQL on Ubuntu is very good because complex joins are performed smoothly and efficiently.
Senior Software Developer at hireHQ
I do not see any limits in scalability for PostgreSQL on Ubuntu; it scales well without constraints.
Director IT at Artizense Hub
 

Stability Issues

Sentiment score
8.0
Docker on Ubuntu provides stable, reliable performance for container deployment, with minor connection challenges and differences in version settings.
Sentiment score
8.3
PostgreSQL on Ubuntu is praised for stability, transaction efficiency, Linux compatibility, and reliable data integrity across diverse applications.
Docker on Ubuntu is very stable.
Software Engineer at INSTITUTE OF AERONAUTICAL ENGINEERING
Docker is continually optimized by the Docker company, and Ubuntu is also continually optimized.
Cloud Ops Lead at a tech vendor with 10,001+ employees
Docker on Ubuntu is very much stable; it is one of the most stable solutions that you can find.
Senior Dev Ops Engineer at 11 East Capital
It also guarantees asset compliance; after atomicity, consistency, isolation, and durability, it means that even if the power goes out during a transaction, PostgreSQL on Ubuntu ensures that the data is 100 percent saved or rolled back.
Agriculturalist/Founder of France Farms at France Farms
PostgreSQL on Ubuntu is quite stable.
Specialist Programmer L3 at Infosys
PostgreSQL on Ubuntu is handling my production infrastructures very well and it is going very good.
Manager Dev Ops at a tech services company with 10,001+ employees
 

Room For Improvement

Docker on Ubuntu requires UI, networking, and storage simplifications with improved documentation, security, and Kubernetes integration.
PostgreSQL on Ubuntu requires improvements in speed, ease of setup, user interfaces, and additional features like AI integration and GUI security.
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
PostgreSQL on Ubuntu is very stable in terms of performance and query optimization.
Software Engineer at a university with 501-1,000 employees
Maybe it makes more sense to use AI for configuration in future updates of PostgreSQL on Ubuntu so that the database is automatically optimized for the best performance for a given hardware.
Head of IT at Givo Pvt Ltd
I would also appreciate the ability to use the EXPLAIN ANALYZE tool.
Consultant at a tech vendor with 10,001+ employees
 

Setup Cost

Enterprise users find Docker on Ubuntu cost-effective, with potential expenses mostly related to staff training and infrastructure.

Founder at Asynka
Docker does not have licensing.
Cloud Operations Engineer at a tech vendor with 51-200 employees
There was no pricing and cost involved in using PostgreSQL on Ubuntu.
Software Engineer at a university with 501-1,000 employees
Now we are running multiple projects on a single Ubuntu VPS with PostgreSQL for around twenty to forty dollars a month total.
CEO at Grant Corporation
Because it is an open source solution, we did not have acquisition or usage costs for this solution.

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.

Consistent use of flexible data and solid transactions has reduced costs and simplified projects
PostgreSQL on Ubuntu could be improved with easier out-of-the-box configuration. The default settings for PostgreSQL on a fresh Ubuntu install are very conservative. Things such as shared buffers and work memory are too low for any real production workloads, and you have to know how to go in and tune it manually. A smart default configuration wizard during installation that detects hardware and suggests settings would save a lot of junior developers from performance headaches. That is important. Built-in connection pooling is another area; PostgreSQL does not handle large numbers of concurrent connections well natively. You end up needing to set up PG Bouncer separately, which is another tool to learn, configure, and maintain. Having a lightweight connection pooler built into the core installation would be a real quality-of-life improvement. Additionally, a better built-in monitoring UI would help. Primarily, if you are working with Ubuntu, you are largely working with PostgreSQL on the command line and installing third-party tools such as pgAdmin or Adminer. A lightweight built-in web dashboard for basic health monitoring would improve projects significantly. Finally, upgrades between major versions and smaller versions should be a lot easier as well. None of these are deal-breakers; they are just nice to have improvements.
