Likelihood to Recommend You are going to be able to find the most resources and examples using Docker whenever you are working with a container orchestration software like Kubernetes. There will always some entropy when you run in a container, a containerized application will never be as purely performant as an app running directly on the OS. However, in most scenarios this loss will be negligible to the time saved in deployment, monitoring, etc.
Read full review Nomad is well suited for organizations who wish to tackle the problem of cloud computing with as little opinion as possible. Where competing tools like Kubernetes limit the concept of "batteries included," Nomad relies on engineers understanding the missing components and filling them in as necessary. The benefit of Nomad is the ability to build a system out of small pieces with the cost of having more complexity at a system level compared to alternatives.
Read full review Pros Packaging of application to limit the space occupied Ease of running the application Provide multiple ways to handle the application issues and integration of different components like pipeline, ansible, terraform etc Read full review Nomad is incredibly simple by nature, following the Linux philosophy of doing one thing great. That one thing for Nomad is job scheduling. Nomad is a modern tool, written in Go with a large community and maintained by HashiCorp. Implementation of Nomad is very simple since it is a single binary. Read full review Cons Docker hub image retention policy can be relaxed Docker hub policies can be more developer friendly Docker CLI help section can be improved Image and container storage (local) management can be optimized Read full review Nomad only handles one part of a full platform. Expertise and vision are required in implementing an entire system that is functional enough for an organization to rely on. This includes other tools to handle things like secrets, service discovery, network routing, etc. Nomad is delayed in some modern functionality, like features for service-mesh and open tracing. These features are on the tool's roadmap, but there's currently no native support. These paradigms can be established still, but require more expertise outside of Nomad itself. Nomad is not the leading tool for this space, and as such risks being left behind by tools with much greater support, such as Kubernetes. Read full review Usability Very easy to use, great tutorials, documentation and cheat sheets out there to help you become a Docker Wiz
Read full review Reliability and Availability Haven't seen any outages, fatal/unrecoverable errors in my usage so far. Enough said.
Read full review Performance Docker Desktop. The CPU high usage is a known issue. Needs fixing. Otherwise, it is great overall. Would not use anything else still.
Read full review Alternatives Considered The reason why we are still using Docker right now is due to that is the best among its peers and suits our needs the best. However, the trend we foresee for the future might indicate Amazon lambda could potentially fit our needs to code enviornmentless in the near future.
Read full review Nomad's primary competitor is Kubernetes, specifically its scheduling component. Kubernetes is a much more complete system that will handle more things than job scheduling, including service discovery, secrets management, and service routing. There also exists a much larger community support for Kubernetes vs Nomad. One might say Kubernetes is the safer choice between the two. Kubernetes is the complete "operating system" for cloud computing, but with it includes complexities that are "Kubernetes" specific. The decision really comes down to a mindset of monolith vs components. With Kubernetes, I would argue you choose the entire system as a whole. With Nomad, you design your system piece by piece. There is no wrong answer.
Read full review Scalability It is the only tool in our toolset that has not [had] any issues so far. That is really a mark of reliability, and it's a testimony to how well the product is made, and a tool that does its job well is a tool well worth having. It is the base tool that I would say any organisation must have if they do scalable deployment.
Read full review Return on Investment Reduces the number of virtual machine which impacted our quarterly billing Using docker with proxy we run multiple application on same port on same host. impact on billing is we have to provide docker training to the people who are working on it. Read full review Nomad has allowed our organization to deploy quicker and more frequently with a lower failure rate. Nomad has brought in consistency from an operations perspective. Nomad's performance allows us to scale infinitely while providing functionality that reduces mean time to repair (canary deploys, versioning, rollbacks, etc). Read full review ScreenShots
