Microsoft System Center Suite is a family of IT management software for network monitoring, updating and patching, endpoint protection with anti-malware, data protection and backup, ITIL- structured IT service management, remote administration and more.
It is available in two editions: standard and datacenter. Datacenter provides unlimited virtualization for high density private clouds, while standard is for lightly or non-virtualized private cloud workloads.
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.
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
For companies with more than 10 Windows devices and needing to standardize the OS, AV, access, share resources, and install software. SCCM is the way to go. This software is unnecessary if the business is all remote users and not in an office-type setting. There are cloud offerings or none to accomplish what a business needs.
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
Needs web based storefront for requesting new software
Needs ability to manage the packaging work flow better
Sometimes is slow to download and there is no indication the entire catalog is being loaded, resulting in confused users not being able to find common software in the available list.
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.
It is not user-friendly for the most part. With IT infrastructure, sometimes it cannot handle excess requests. Every few months, you will need an upgrade in terms of server resources to keep up with incoming alerts and requests. This does not happen all of the time, but it does happen when there are too many requests.
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.
If I had to dislike something about the system it would be how much it changes once you upgrade. This could be more of a problem of mine since I get used to one way and don't like it when it changes so much. I am enjoying the newest update, but it is a mess when you are actually going through the upgrades.
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.
We previously used a mix of FOG and Clonezilla to image machines. The biggest issues with these products is that changing one piece of the image required you to rebuild the entire image itself. These pieces of software also did not allow you to manage applications and Windows Updates, causing IT to have to constantly touch machines after they were imaged and update or manage them with a much more hands on approach.
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.
We have been able to automate our patch management, firmware and other security concerns.
We have a standardized "image" ensuring our setup is consistent across the enterprise. This alone has saved us in time to support and time to understand how to use our desktops.
