Juniper JNCIS-SEC JN0-335 Question # 27 Topic 3 Discussion

vSRX is a virtual firewall that provides security and networking services at the perimeter or edge of virtualized environments1. vSRX can be deployed in various cloud environments, such as AWS, Azure, Google Cloud Platform, and VMware2.

AWS is a cloud computing platform that offers a variety of services, such as compute, storage, networking, security, and analytics3. AWS enables customers to deploy vSRX instances in a virtual private cloud (VPC), which is a logically isolated section of the AWS cloud4.

AWS satisfies the requirements for a vSRX deployment as follows:

Globally distributed: AWS has a global infrastructure that spans 25 geographic regions and 81 availability zones3. Customers can deploy vSRX instances in any region or zone that meets their needs and preferences4.

Rapid provisioning: AWS allows customers to launch vSRX instances in minutes using the AWS Marketplace, which is an online store that offers software products and solutions5. Customers can also use automation tools, such as CloudFormation, Terraform, and Ansible, to provision vSRX instances in a consistent and scalable manner.

Scale based on demand: AWS supports horizontal and vertical scaling of vSRX instances based on the changing traffic and performance demands. Customers can use AWS Auto Scaling, which is a service that automatically adjusts the number of vSRX instances, or AWS Elastic Load Balancing, which is a service that distributes the traffic across multiple vSRX instances.

Low CapEx: AWS operates on a pay-as-you-go model, which means that customers only pay for the resources they use, such as the vSRX instance type, the storage volume, the data transfer, and the license. Customers can also benefit from the AWS Free Tier, which offers a limited amount of free resources for 12 months.
