transit VPCs The AWS transit VPC is used to create a global network transit hub that interconnects geographically separated remote networks and your VPCs. transit VPCs reduce the number of connections needed when interconnecting VPCs and remote networks by eliminating the need to create mesh connections between VPCs. transit VPCs and Transit Gateway service instances […]

Getting hands-on with Amazon SageMaker’s training and inference instances In this section, you will learn about training a model and hosting the model to generate its predicted results. Let’s dive in by using the notebook instance from the previous example: Figure 9.7 – The InService instance Figure 9.8 – The SageMaker fit API call Figure […]

Identity and Access Management (IAM) is used to manage access into the Transit Gateway service, and users and groups can be applied to define access permissions. Automated provisioning is included with the service that automatically discovers site-to-site VPN connections and other remote networks connecting into your account. SD-WAN offerings from major vendors are also supported. […]

Getting hands-on with Amazon SageMaker notebook instances The very first step, in this section, is to create a Jupyter Notebook, and this requires a notebook instance. You can start by creating a notebook instance, as follows: Figure 9.3 – Amazon SageMaker role creation sh-4.2$ cd ~/SageMaker/ sh-4.2$ git clone https://github.com/PacktPublishing/AWS-Certified-Machine-Learning-Specialty-MLS-C01-Certification-Guide-Second-Edition.git Figure 9.4 – Jupyter Notebook […]

The Route Table and Network ACL Tabs The Route table and Network ACL tabs allow you to view the associated route table and NACL with the subnet and make changes as necessary. The following screenshot shows a default route (local) with another route pointing to the NAT gateway. The NAT gateway handles internet requests (0.0.0.0/0) […]

AWS CloudFormation Another option for deployment is to use AWS CloudFormation. CloudFormation is a service that lets you provision all sorts of AWS resources, offering an IaC approach. You define your resources in one or multiple templates, written in either YAML or JSON. YAML is typically easier and less verbose, compared to JSON, for humans […]
