HashiCorp Consul vs. IBM Cloud Managed Istio vs. IBM DevOps Code ClearCase

Consul can provide a light-weight, lightning-fast and robust solution for the following:

• Network mesh
• Service DNS
• Global key-value store (values can be complex objects as well)
• Utility for blue-green deployments
• Service health checking

Consul can be used in any or a combination of these scenarios. Regardless if you are a network administrator or a regular software engineer, Consul can add value to your work.

Clearly, the [IBM Cloud Managed Istio] tool is very useful when you have multiple services and each service is connecting with other services through APIs in different networks. To manage this type of complex network, [IBM Cloud Managed Istio] is very useful. It comes with a license that can increase the billing of your project so make sure if your application network mesh, monitoring cannot be managed on your own then you can use it. If your application is not very complex then you have many tools available like Grafana, Prometheus, Sumo Logic, which you can integrate individually with your cluster and implement. In this type of scenario, it is better to not use [IBM Cloud Managed Istio] and it will serve your purpose as well.

IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control

• Key-Value database management.
• Service discovery.
• Centralized configuration database with native high availability.

• Layers transparently onto existing applications
• Allows control of access and rules to be developed
• Creates metrics for usage

• Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
• Rational ClearCase handles parallel development of many dependent applications really well.
• The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.

• The GUI: The GUI interface for Consul has gotten a lot better over the years. Since Consul is so easy to interact with via API, this isn't a showstopper, but for those that are less command line inclined it's always nice to be able to refer them to an easy to use and understand web interface
• It's chatty: Consul is extremely chatty. Sometimes it's particularly chatty at 2am with no indication as to why and eats up quite a bit of resources. Just be sure to provision your systems that typically take a heavy load with a little extra for Consul

• Some more functionalities added could improve it better.
• Better technical user guidance.

• Extremely buggy.
• Sometimes the repository gets locked for no reason.
• Slow.

Consul's API is extremely user friendly. While their web interface isn't quite as "mature", it's still pretty easily navigated for the average person. Together they make a pretty easy to pick up and use tool.

I've never used paid support from HashiCorp, but I consider its support a good one, since they provide a lot of free resources for the community and there are good user groups supporting you on several sorts of issues. Also, HashiCorp is known as a company with a strong relationship with the community, that is easily noticed by the events HashiCorp promotes over the world.

Consul was easier to configure out of the box than Serf and gave us more initial options. Its easy to use tools and support were by far superior to Serf in many ways. Support alone was one of those areas that Serf could take an example from Consul to keep its customers happy.

If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.

• It contains a native web UI, which in contrast to its counterparts, is handy, very intuitive and - most importantly - very informative. It leaves no room for doubt about your services "forest" health. So, for that purpose, the learning curve was almost down to non-existent. Our team managed to work seamlessly with Consul being our services API
• Our management staff had a difficult time understanding what Consul was really all about. For technical staff it is pretty simple to understand the huge value such a tool can pose to our suite of solutions, but once our management staff took the grasp of its valuable handy set of tools, we didn't take long to start using it and keeping track of our Swarm overall health, with was a constant concern for the entire company before.
• For load balancing purposes, we were relying pretty much on guesses before we decided to use Consul. One would check a certain node overall health and decide if we would need to spring a new instance at AWS or Digital Ocean.

• It reduced the complexity of network mesh (ingress/egress services).
• One tool with many solutions. No need to integrate monitoring tools or notification tools.
• It reduced the number of lines of YAML code.
• It reduced the number of labor hours.

Incentivized

• Managed code versioning for many years.
• Only one person can edit code at a time - slows processing down.
• IBM is an expensive product to support.
