From a visibility and observability standpoint hybrid connectivity brings in new elements that make the job of IT teams far more complex.

I’ll take you through, three layers from where we host applications to the networks that sit in between users and applications. If you look at the hosting part the first thing is one. You don’t have access to the infrastructure layer on which those applications are hosted.

When you start using SaaS applications and PaaS applications, or you start using microservices. It’s far more complicated to instrument those, that’s number one. Number two is those applications by nature are for more distributed, In the very, in the early days, we, we had a simplistic view of SaaS, for example, where users would connect through the internet to one location where the SaaS platform would be.

The reality is actually far different from that. When you connect to your SaaS platform, you connect to 20 or 30 years names and each one’s name actually. Texts you to a different place depending on where you connect from which operator from which location in the world. The result in matrix is far more complex.

And for example, capturing traffic on things like that is almost like impossible. And there is a second layer of complexity and challenges that come from the evolution of the network. How we go through the network. We go through strong encryption when we connect to those services, you probably heard of perfect forward secrecy which brings in new encryption schemes that are almost impossible to, to decrypt.

And that takes away somebody from anything that relied on traffic analysis to monitor . So that’s one, the second one is the the appearance of zero trust networks and CASB while they bring in more complexity, because every time you connect to a CASB you go, through a DNS resolution, you are redirected to node valid dynamic.

The path you are taking to that can be node can also be dynamic and change through time. Of course from GB too, the actual workload, you’ve got the exact same system, so DNS redirection, public networks. And that makes the, understanding the connectivity between the end to end connectivity between the user and the workload for more conference.

And finally sometimes we simply put a layer like an easy one on top of the public connectivity but while we had. Process of dynamic behavior with the 81. The underlay connectivity is also dynamic. Can change paths, can change look at the the location through different resolutions.

And if you monitor only the overlay there are good chances that you do not understand why the purpose of that overlay changes. If you don’t have control on the underlay. And finally the users, the users are distributed and each user is also having multiple locations to work from.

People work from the office. People work from anywhere. They travel, they work from home. They use multiple sets of connectivity to do that. And that’s also a challenge variety because supporting users and making sure they work efficiently from all of those places brings, it brings new set of challenges.

And the performance rate that were acceptable before when working from home was an exception are no longer acceptable these days. And the lack of activity we had on that part of the user access is unacceptable these days. So that’s for the challenges that hybrid connectivity brings in.

And the outcome of that is that, the traditional solution we’ve put in place, for network traffic analysis in the data center times cannot really make the the move to that new environment.
