Real Talk: Top 3 Concerns Surrounding Containerization

Part 3 of our interview on containerization with Red Hat’s Global Solutions Architect Leader, Thomas Cameron

This is the third part of a three-part blog series where we sat down with Red Hat’s Global Solutions Architect Leader, Thomas Cameron (@ThomasDCameron) to discuss his views on containerization.

As is the case with almost any technology, there are a number of concerns that must be considered when using containerization in an enterprise setting. We’ve laid out the top three things to consider first that we are seeing in the marketplace.

1. Security: As discussed in blog #2, security can be both a benefit and concern of containerization. As Cameron points out, “If you’re not paying attention, you can have situations where a developer rolls out a container, forgets about it and then moves on to something else, leaving a large vulnerability out there.” If systems aren’t in place to catch these orphaned containers, companies could be in real trouble if a hacker gained access to one of these instances.”

This was a similar concern when Virtualization first was deployed in enterprise environments. Software monitoring has almost eliminated this concern in virtualized environments to where this is the primary method of rolling out new applications. These same software vendors will be developing the same strategy when it comes to containers.

2. Newness of the technology: Because containerization is relatively new, there isn’t a huge pool of potential applicants with significant experience. While this is a bit of a short-term challenge, it will likely become less so as more people are educated on this technology.

Today, new technology is something that millennials are looking for as part of their job description. These type of concerns become an asset when hiring the best talent.

3. Competing technologies: There are a lot of competing technologies out there for both the core container technology, as well as for the orchestration and management of those containers. Since the technology isn’t very mature, you have the potential of several technologies falling by the wayside once a true leader emerges.

And, by the way, this is the case with any new technology. If you look at the latest trend – Virtualization. There was a lot of vendors that had their own hypervisor technology. And they are all still around today, even though VMware is still the prominent solution, they all have a place in the market.
