Term 242
Resource hierarchy is the structured, parent-child ordering of cloud resources that governs access control, policy inheritance, and resource organization across a cloud platform.
Term 243
A route is a path that data takes through a network from one device or network to another, determined by routing protocols and configured rules.
Term 244
Route 53 is Amazon Web Services’ cloud-based Domain Name System (DNS) web service that translates human-readable domain names into IP addresses and routes end-user requests to internet applications.
Term 245
Route summarization is a technique that combines multiple network routes into a single, more general route advertisement to reduce the size of routing tables and improve network performance.
Term 246
A route table is a set of rules, called routes, that determine where network traffic from a subnet or virtual network is directed.
Term 247
A router is a networking device that connects different networks together and directs data traffic between them by choosing the best path for data to travel.
Term 248
A Router Advertisement is a message sent by a router on a network to inform devices about the router's presence and provide them with essential configuration information for communication.
Term 249
The Router ID is a unique 32-bit identifier assigned to a router running the OSPF routing protocol, used to distinguish it from other routers in the network.
Term 250
A router-on-a-stick is a network configuration where a single router interface is used to route traffic between multiple VLANs by connecting to a switch through a trunk link.
Term 251
A routing table is a data set stored in a router or host that contains information about network paths and is used to determine where to forward data packets.
Term 252
An S3 bucket policy is a JSON-based resource-based access control document that defines who can access an Amazon S3 bucket and its objects, and what actions they can perform.
Term 253
S3 event notification is an AWS feature that automatically sends a message to a destination service when a specific event occurs in an Amazon S3 bucket.
Term 254
Amazon S3 Glacier is a secure, durable, and extremely low-cost cloud storage service designed for long-term data archiving and backup, where data is rarely accessed but must be retained for months or years.
Term 255
An S3 lifecycle policy is a set of rules that automatically transitions objects between storage classes or deletes them after a specified time to optimize cost and manage data lifecycles.
Term 256
S3 Object Lock is an AWS feature that allows you to set a retention period or a legal hold on objects in Amazon S3 to prevent them from being deleted or overwritten.
Term 257
S3 replication automatically copies objects from one Amazon S3 bucket to another to improve data durability, availability, or compliance.
Term 258
S3 versioning is an Amazon S3 feature that keeps multiple versions of an object in a bucket, so you can recover from accidental deletion or overwrite.
Term 259
Same-Region Replication is the automatic, asynchronous copying of data between storage systems within the same geographic region to provide durability and availability.
Term 260
A screened subnet is a network architecture that places a buffer network, often called a DMZ, between an internal trusted network and an external untrusted network, using two firewalls to control traffic.
Term 261
A Secret Manager is a centralized tool that securely stores, manages, and controls access to sensitive information like passwords, API keys, and certificates, often automating their rotation and injection into applications.
Term 262
A secure web gateway (SWG) is a security solution that protects users and organizations from web-based threats by filtering internet traffic, enforcing security policies, and blocking access to malicious or unauthorized websites.
Term 263
Serverless is a cloud computing model where the cloud provider manages the servers, and you only pay for the actual compute time your code uses, without having to worry about provisioning or maintaining infrastructure.
Term 264
Serverless architecture is a cloud computing model where the cloud provider automatically manages the infrastructure, allowing developers to build and run applications without thinking about servers.
Term 265
Serverless computing is a cloud execution model where the cloud provider dynamically manages the allocation and provisioning of servers, allowing developers to write and deploy code without thinking about the underlying infrastructure.
Term 266
A serverless function is a single-purpose piece of code that runs in the cloud only when triggered, without you managing any servers.
Term 267
Serverless security is the practice of protecting applications that run on serverless computing platforms, where the cloud provider manages the infrastructure and the customer is responsible for securing the code, data, and access controls.
Term 268
A service is a software component or system that performs a specific function and is available to be used by other programs or users over a network.
Term 269
A service account is a special type of account used by an application or a virtual machine, rather than a human user, to authenticate and interact with cloud services and APIs securely.
Term 270
A service account key is a credential file used to authenticate and authorize a non-human user, like an application or a virtual machine, to access Google Cloud resources.
