Summary This chapter on inter-VPC and multi-account networking was a continuation of the previous chapter on hybrid networks. You learned about how to interconnect and access VPCs both inside and between accounts including VPC sharing, peering, and PrivateLink. Common VPC network architectures were presented including the Transit Gateway, Transit Gateway Connect, and transit VPCs. WAN […]

Configure cost center quotas One of the key factors in managing an Azure subscription is being able to plan for and drive organizational accountability for Azure spend. One of the best ways to drive accountability is to make sure that the consumers of Azure resources understand their cost, including current usage and forecasting future spend […]

Note This book concentrates on security and how to create secure network connections in AWS and presents the information on network connectivity needed for the AWS Certified Security – Specialty exam. Networking in AWS, the cloud, and as a practice is a much larger topic, and it is recommended you dive into it further. This […]

Note If Cisco NX-OS receives no MED attribute with the path, Cisco NX-OS considers the MED to be 0 unless you configure the best-path algorithm to set a missing MED to the highest possible value. e. If the nondeterministic MED comparison feature is enabled, the best-path algorithm uses the Cisco IOS style of MED comparison. […]

Configure cost management In Azure, there are several types of quotas that are applicable to subscriptions, including resource quotas and spending quotas. With Azure resource quotas (or limits), Azure adminis- trators can view the current consumption and usage of resources within an Azure subscription and understand how that consumption can be affected by Azure resource limits. Administra- […]

Relational Operators We now move on to relational operators, which compare two expressions and return a boolean value. Table 2.8 describes the relational operators you need to know for the exam. TABLE 2.8 Relational operators Operator Example Description Less than a < 5 Returns true if the value on the left is strictly less than […]

Active Directory Active Directory provides a centralized management application for Microsoft Windows computers and user administration. The AD architecture is a distributed hierarchical database for information about your IT infrastructure, containing configuration and management for users, user credentials, and access rights based on group memberships, DHCP, policy management, DNS zones and records, applications and devices, […]

OSI Networking Model and Terminology At one point in the history of the OSI model, many people thought that OSI would win the battle of the networking models discussed earlier. If that had occurred, instead of running TCP/IP on every computer in the world, those computers would be running with OSI. However, OSI did not […]

Limitations of VPC Peering Although VPC peering is relatively easy to understand and implement, there are some limitations that you must be aware of as well: The preceding list was of the most prevalent rules. For a complete list of VPC peering limitations, visit the following URL: https://packt.link/Jkkhv. Using Transit Gateway to Connect VPCs Transit […]

Configure management groups Management groups can also be used to apply Azure RBAC to a subscription. Using man- agement groups, you can apply governance consistently across subscriptions, including the application of common RBAC controls and the application of Azure Policy, as discussed later in this chapter. Within management groups, subscriptions can be organized in a multi level […]
