AWS Backup Vault Lock protects recovery points from deletion and lifecycle changes that would violate the vault-lock configuration. It is designed for write-once-read-many style backup governance, including environments where an attacker or administrator with broad credentials must not be able to shorten retention or remove recovery points before they expire. Inside the AWS Architecture and […]
CloudFront origin failover lets a distribution use a secondary origin when the primary origin cannot serve an eligible request. The feature is configured through an origin group with a primary and secondary origin plus one or more failover criteria such as connection failure or selected HTTP status codes. Inside AWS Architecture and Operations, origin failover […]
CloudWatch Application Signals gives teams an application-centric view of service health by discovering services and dependencies, collecting standard metrics and traces, and letting operators define service level objectives. Instead of starting with hundreds of infrastructure metrics, the team can start with a service or operation and ask whether it is available, fast enough, and meeting […]
CloudWatch Metric Math lets teams combine, transform, and compare CloudWatch metrics into new time series. A simple expression can calculate error rate from errors and invocations, convert bytes to megabytes, compare used capacity with a limit, or compute a service-level indicator that is more meaningful than any raw metric alone. Inside AWS Architecture and Operations, […]
AWS cost allocation tags turn technical resource metadata into billing dimensions that can be used in Cost Explorer, Cost and Usage Reports, Budgets, Cost Categories, and other cost-management workflows. The hard part at scale is not creating one tag. It is maintaining a small, stable tagging vocabulary across accounts and services so costs remain attributable […]
AWS Direct Connect resiliency depends on more than having two circuits. The location, device, provider path, BGP design, virtual-interface configuration, and failover testing all determine whether a second connection is actually independent enough to carry traffic when the first path fails. Inside AWS Architecture and Operations, Direct Connect is the hybrid-network path that connects on-premises […]
EC2 Auto Scaling warm pools reduce scale-out latency for applications whose instances take a long time to initialize. Instead of launching every instance from zero when demand rises, Auto Scaling can maintain a pool of pre-initialized instances in stopped, hibernated, or running states and move them into service as needed. Inside AWS Architecture and Operations, […]
