We all want lightning-fast websites and applications, but how do we prioritize our efforts in order to have the biggest impact on performance? Join our expert team as they share best practices when identifying bottlenecks, monitoring optimizations, and communicating the impact of their work to the wider team.

By default, pods are non-isolated; they accept traffic from any source. The Kubernetes solution to this security concern is Network Policy that lets developers control network access to their services. Rancher comes configured with Network Policy using Project Calico which can be used to secure your clusters. This class will describe a few use cases for network policy and a live demo implementing each use case.

Kubernetes Pod Security Policies (PSPs) is an enforcement mechanism to ensure that Pods run only with the appropriate privileges and can solely access the appropriate resources. You can leverage them as a threat prevention mechanism by controlling Pod creation, and limiting the capabilities available to specific users, groups, or applications.

Applications such as WordPress or MySQL require the use of data persistence. It is common when deploying such applications to use a HostPath volume as it is agnostic from the platform. A HostPath volume shares the filesystem of the Host within the container making the data available between pod restarts. However, it ties the data to one node only, creating a single point of failure and restricting any kind of scalability. Kubernetes is not able to schedule the application in any other node even if it is unavailable. This leads to eventual data loss.

With growth often comes complexity - especially when search is involved. How do you maintain autonomy across independent search engines while bundling engines into a single search bar?

Many details must come together to make a great search experience stand out from the rest, including how the users themselves interact with the query and results. But if you've tried to build this from scratch, you've already realized how complex it can be to make things simple and elegant for the end user.
