GFS is well suited for DEVOPS type environments where organizations prefer to invest in servers and DAS (direct attached storage) versus purchasing storage solutions/appliances. GFS allows organizations to scale their storage capacity at a fraction of the price using DAS HDDs versus committing to purchase licenses and hardware from a dedicated storage manufacturer (e.g. NetApp, Dell/EMC, HP, etc.).

TeamCity is very quick and straightforward to get up and running. A new server and a handful of agents could be brought online in easily under an hour. The professional tier is completely free, full-featured, and offers a huge amount of growth potential. TeamCity does exceptionally well in a small-scale business or enterprise setting.

Scales; bricks can be easily added to increase storage capacity
Performs; I/O is spread across multiple spindles (HDDs), thereby increasing read and write performance
Integrates well with RHEL/CentOS 7; if your organization is using RHEL 7, Gluster (GFS) integrates extremely well with that baseline, especially since it's come under the Red Hat portfolio of tools.

Documentation; using readthedocs demonstrates that the Gluster project isn't always kept up-to-date as far as documentation is concerned. Many of the guides are for previous versions of the product and can be cumbersome to follow at times.
Self-healing; our use of GFS required the administrator to trigger an auto-heal operation manually whenever bricks were added/removed from the pool. This would be a great feature to incorporate using autonomous self-healing whenever a brick is added/removed from the pool.
Performance metrics are scarce; our team received feedback that online RDBMS transactions did not perform well on distributed file systems (such as GFS), however this could not be substantiated via any online research or white papers.

The customization is still fairly complex and is best managed by a dev support team. There is great flexibility, but with flexibility comes responsibility. It isn't always obvious to a developer how to make simple customizations.
Sometimes the process for dealing with errors in the process isn't obvious. Some paths to rerunning steps redo dependencies unnecessarily while other paths that don't are less obvious.

TeamCity runs really well, even when sharing a small instance with other applications. The user interface adequately conveys important information without being overly bloated, and it is snappy. There isn't any significant overhead to build agents or unit test runners that we have measured.

Gluster is a lot lower cost than the storage industry leaders. However, NetApp and Dell/EMC's product documentation is (IMHO) more mature and hardened against usage in operational scenarios and environments. Using Gluster avoids "vendor lock-in" from the perspective on now having to purchase dedicated hardware and licenses to run it. Albeit, should an organization choose to pay for support for Gluster, they would be paying licensing costs to Red Hat instead of NetApp, Dell, EMC, HP, or VMware. It could be assumed, however, that if an organization wanted to use Gluster, that they were already a Linux shop and potentially already paying Red Hat or Canonical (Debian) for product support, thereby the use of GFS would be a nominal cost adder from a maintenance/training perspective.

TeamCity is a great on-premise Continuous Integration tool. Visual Studio Team Services (VSTS) is a hosted SAAS application in Microsoft's Cloud. VSTS is a Source Code Repository, Build and Release System, and Agile Project Management Platform - whereas TeamCity is a Build and Release System only. TeamCity's interface is easier to use than VSTS, and neither have a great deployment pipeline solution. But VSTS's natural integration with Microsoft products, Microsoft's Cloud, Integration with Azure Active Directory, and free, private, Source Code repository - offer additional features and capabilities not available with Team City alone.

TeamCity has greatly improved team efficiency by streamlining our production and pre-production pipelines. We moved to TeamCity after seeing other teams have more success with it than we had with other tools.
TeamCity has helped the reliability of our product by easily allowing us to integrate unit testing, as well as full integration testing. This was not possible with other tools given our corporate firewall.
TeamCity's ability to include Docker containers in the pipeline steps has been crucial in improving our efficiency and reliability.
