Reusing Common Patterns As your environment expands on AWS, you may identify a need to reuse the same resource configurations over and over from one stack to the next across teams or projects. For instance, you may want to implement best practices across various projects by enforcing some specific guidelines in their infrastructure resource configurations, […]

The golden record As we now know, the golden record, or single source of truth, is essentially a data record where the definitive source of information is stored in order to orchestrate business operations. Users should be able to view a golden record to see the correct version of a piece of information. While the […]

Operator Precedence When reading a book or a newspaper, some written languages are evaluated from left to right, while some are evaluated from right to left. In mathematics, certain operators can override other operators and be evaluated first. Determining which operators are evaluated in what order is referred to as operator precedence. In this manner, […]

TCP/IP Transport Layer Although many TCP/IP application layer protocols exist, the TCP/IP transport layer includes a smaller number of protocols. The two most commonly used transport layer protocols are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). Transport layer protocols provide services to the application layer protocols that reside one layer higher […]

The Details Tab The Details tab provides a high-level overview of data surrounding the route table, detailing which VPC it resides in, the account owner ID, the route table ID, and any explicit associations, as shown in the following screenshot. Figure 10.14: The Details tab These explicit associations relate to any subnets that have been […]

Note The backbone area 0 cannot be an NSSA All OSPF areas must physically connect to area 0 (backbone area). If one area cannot connect directly to area 0, you need a virtual link. Virtual links allow you to connect an OSPF area ABR to a backbone area ABR when a direct physical connection is […]

7.3  Bulk Processing for Large Datasets Collections like lists, sets, and maps are essential for bulk processing. They allow you to group and manipulate records efficiently. Fetch required data outside the loop and use collections to match and process records. Utilize bulk DML operations to update, insert, or delete multiple records in a single transaction. […]

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 […]
