X-Forwarded-For Protocol Since the application load balancer terminates the connection from the client and establishes a backend session to the target servers, the IP addressing will change along the path. The downside to this is that the target servers do not see who originated the packet since the load balancer has changed the source IP […]

AWS Certificate Manager The AWS Certificate Manager allows you to create both public and private digital certificates and has integrated the service into the application load balancer, as shown in Figure 4.6. This integration allows you to specify an AWS certificate directly from the ALB configuration GUI, API, and CLI. The Certificate Manager service enables you […]

Anything that happens in your accounts from an infrastructure standpoint is captured in some type of log. To pass the security specialty exam and set up a secure AWS environment, it is necessary to grasp which logs contain what type of values. This section takes you through logging and monitoring in AWS and the invaluable […]

Storing the training data First of all, you can use multiple AWS services to prepare data for machine learning, such as Elastic MapReduce (EMR), Redshift, Glue, and so on. After preprocessing the training data, you should store it in S3, in a format expected by the algorithm you are using. Table 6.1 shows the list […]

Staging Some organizations utilize a staging environment to replicate the production environment. This staging environment can be used for several different purposes, including determining potential problems in the production environment and as a replacement when the production environment fails or is compromised. It is also used when implementing a blue/green deployment (see the following section […]

Designing Interactions in a Distributed System to Prevent Failures One of the aspects that influences a distributed system most is communication between the different elements of the system. There is already quite a number of things that can go wrong in a simple client-server scenario; that number becomes simply mind-boggling in a large microservices architecture. […]

2.1  Standard and Customer Objects Salesforce objects and fields are analogous to database tables and the table columns. Objects are tables that store specific data in Salesforce. The Salesforce platform has standard objects and custom objects. Standard objects are objects that are included with Salesforce, while custom objects are objects that are created by users […]

Traffic Mirroring Network traffic captured in a VPC can be forwarded to a load balancer for analysis and troubleshooting. Mirroring is configured in the VPC and can send the traffic to a network load balancer listener to distribute the captured traffic to target groups associated with the NLB. Gateway load balancing is also supported, which […]
