Containerization has accelerated testing cycles and consistently reduced time to market
Docker on Ubuntu 18.04 LTS is a very mature product, and I don't think there is a lot of improvement that they need to do on their end. The Docker team is coming up with new features, and integration with the IDE, for example, would be amazing. Support on Windows is not so great from Docker, so that is something that they could examine. I chose nine out of ten for Docker on Ubuntu 18.04 LTS because I think they could improve a little more on optimization. It sometimes demands a lot of RAM and computing power, so that is one area that the Docker team could improve upon.

Zero trust security has provided flexible protection and inspects real-time traffic effectively
From my perspective, I think about Zscaler Software [Private Offer Only], not much could be improved. It is working very well. The only thing is about the POP presence, where you hook into a continent or country. In some countries, South America has some coverage, but not as much as for instance North America or Europe. If you talk with large enterprises or multinationals that are everywhere in the world present, they might need something in Africa. Africa is also a continent where you have more and more enterprises having their subsidiaries there. Africa is not covered very thoroughly, in my opinion. It only has South Africa with points of presence and then Egypt. It is either very up north or very down south. If you are in the middle of Africa, which is an extremely large continent, then you have delays and latencies. That is not very nice. However, that is not only counting for Zscaler Software [Private Offer Only]; this is also for all competitors. I am working with Cato Networks now for more than a year and the same story applies to them. I also know other competitors of Zscaler Software [Private Offer Only] which have even less coverage. It is not something that I think everyone is keen on to expand in Africa because they do not see much traffic. However, if you have multinationals that are operating in Africa, then you cannot offer very good quality service because you have large latency if they are in the middle of Africa. Not even in the middle of Africa; if you talk about under Morocco, then you either connect to Cairo or you connect to Spain. Spain is closest, but if you always have redundancy, and if Spain falls out for whatever reason, even though that is not happening much because the data centers are very stable, then you have an enormous latency going to Cairo. Coming with this to more North Africa, if you talk about Angola and Mozambique in the middle of Africa, then you do not have much choice. You always have a lot of latency there. That is unfortunate. On the technical terms, that is where I stand. I mentioned this before, and it is still the same. I think I talked with you a few years back about this; I think three or four years ago. I mentioned exactly this topic then, and it is still the same. The other thing is, I think in terms of software, they are doing their best. They are buying in firms and buying in solutions, so they are expanding, and that is fine. I would rather say to Zscaler Software [Private Offer Only] to have better customer service because Zscaler Software [Private Offer Only], even with large enterprises and huge companies that I work for, they notice that Zscaler Software [Private Offer Only] service management is different. They are very big and they have less attention to client matters. If that would improve, it would be the best for Zscaler Software [Private Offer Only] to have better customer success managers, but more attention to clients and more direct interface to the deep core of the company for client matters if they have questions or specific things that they do not currently have. If I have something with the client, I have sometimes to escalate to the vice president that I know because I worked with him before, and that is unfortunate. That should not be necessary to go that route. You should have things arranged directly with an account manager or customer success manager of your client if you have problems, or at least have responses saying, this is impossible, we cannot do that because of this, this, this, whatever. At least you should have an answer. I think in the future, everyone in the branch is focusing on AI and quantum computing as a mix. I think on that end, everyone in the domain is working hard to find the best solutions against those two challenges. I think Zscaler Software [Private Offer Only] is doing their best as well there. That is the challenge for the upcoming years, to get the best answers to it. Eventually, they will compete with the same; fight it back with the same power. That means also with quantum computing or specially designed AI to attack back when attackers are attacking. I am not the genius saying that there will be a sort of war game coming up in the future in this domain. However, they are working on it, as all the others are doing, and I think that is absolutely the focus for the coming years because that is where everyone has concern about.
