Workload security in a Cloud Native Security Platform (CNSP) is designed to secure containers, VMs, and serverless functions throughout the entire application lifecycle — from development to runtime — by detecting and blocking vulnerabilities, misconfigurations, and runtime threats.

Multitenancy is a key characteristic of the public cloud, and an important risk. Although public cloud providers strive to ensure isolation between their various customers, the infrastructure and resources in the public cloud are shared. Inherent risks in a shared environment include misconfigurations, inadequate or ineffective processes and controls, and the “noisy neighbor” problem (excessive network traffic, disk I/O, or processor use can negatively impact other customers sharing the same resource). In hybrid and multicloud environments that connect numerous public and/or private clouds, the delineation becomes blurred, complexity increases, and security risks become more challenging to address.

Elastic scalability is the feature of the VM-Series firewalls that allows them to fully integrate into the DevOps workflows and CI/CD pipelines without slowing the pace of business. Elastic scalability means that the VM-Series firewalls can automatically adjust their capacity and performance based on the changing demand and workload of the applications they protect. This enables the VM-Series firewalls to provide consistent and optimal security across multiple cloud environments, while also reducing operational costs and complexity. Elastic scalability also allows the VM-Series firewalls to seamlessly integrate with automation and orchestration tools, such as Terraform, Ansible, and AWS CloudFormation, that are commonly used in DevOps processes. This way, the VM-Series firewalls can be deployed and managed as part of the application development lifecycle and CI/CD pipelines, ensuring that security is always aligned with the business needs and objectives. References: VM-Series Virtual Next-Generation Firewall - Palo Alto Networks, Securing Multi-Cloud Environments with VM-Series Virtual Firewalls, Terraform Modules for Palo Alto Networks VM-Series on AWS.

DevOps is not:

● A combination of the Dev and Ops teams: There still are two teams; they just operate

in a communicative, collaborative way.

● Its own separate team: There is no such thing as a “DevOps engineer.” Although some

companies may appoint a “DevOps team” as a pilot when trying to transition to a

DevOps culture, DevOps refers to a culture where developers, testers, and operations

personnel cooperate throughout the entire software delivery lifecycle.

● A tool or set of tools: Although there are tools that work well with a DevOps model or

help promote DevOps culture, DevOps ultimately is a strategy, not a tool.

● Automation: Although automation is very important for a DevOps culture, it alone does

not define DevOps.
