12.3 Load Balancing and Redundancy Flashcards
__________ and __________ need to understand cloud architecture in order to test the security settings for a given environment.
**Cloud security analysts** and **cloud penetration testers** need to understand cloud architecture in order to test the security settings for a given environment.
What does a cloud architect do?
**Cloud architects** build out cloud environments for an organization and are expected to understand how to build in security from the ground up.
What is DevSecOps responsible for?
**DevSecOps** are responsible for maintaining production and testing environments for an organization’s developer and QA testing teams. They are expected to build and maintain secure systems at every step of the development process.

Review: What is Ansible?
Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code.
True or False: A load balancer provides the external IP address that the rest of the internet can access. Then, it receives traffic that comes into the website and distributes it across multiple servers.
True
One way to mitigate DoS attacks is to have multiple servers running the same website, with a _______ in front of them.
One way to mitigate DoS attacks is to have multiple servers running the same website, with a **load balancer** in front of them.
A load balancer typically also has a ________ function.
Health probe
This function checks regularly to make sure all of the machines behind the load balancer are functioning before sending traffic to them. Machines with issues are reported, and the load balancers stop sending traffic to those machines.
Load balancing works by forwarding traffic from specific ports to the ________ of machines on specific ports.
Load balances work by forwarding traffic from specific ports to the backend pool of machines on specific ports.
What does a redundant setup mean?
A redundant setup means having a few exact copies of something. If one server goes offline, the other server will continue to host the website. Multiple servers are often used in a setup like this. The more servers you use, the more resilient the website.
