Databases premium PostgreSQL high availability PostgreSQL high availability means Azure keeps a standby flexible server ready so the database can continue after certain failures or planned failover events. Instead of relying on one server instance, the primary and standby are kept in sync. Depending on the design, the standby can be in the same availability zone or a different zone. This reduces downtime risk, but it does not remove every responsibility. Applications still need retry logic, connection handling, monitoring, tested failover procedures, and a cost owner because high availability adds real infrastructure.

Databases premium PostgreSQL log analytics PostgreSQL log analytics means collecting PostgreSQL flexible server logs in Azure Monitor so operators can search them, build alerts, and investigate problems with KQL. Instead of downloading log files manually or guessing from symptoms, teams route PostgreSQLLogs and related categories to a Log Analytics workspace. The value comes from patterns: failed connections, slow queries, audit events, PgBouncer signals, configuration effects, and workload changes. It is not free and not automatically useful; teams must choose categories, retention, workspace access, alert logic, and dashboards that match the database risk.

Azure SQL Managed Instance intermediate 3 commands Aliases: Managed Instance failover group, Azure SQL Managed Instance Quick peek Open full term page

Identity premium Assignment managed identity Assignment managed identity is the identity Azure Policy uses when a policy assignment must change resources during remediation. It matters most for effects such as modify and deployIfNotExists, where Policy is not just reporting non-compliance but attempting to fix or deploy something. The identity needs Azure RBAC permissions at the right scope. Without those. Azure Policy intermediate 2 commands Aliases: Policy assignment identity, Azure Policy managed identity, policy remediation identity, assignment identity Quick peek Open full term page

Databases field-manual-complete PostgreSQL stop/start PostgreSQL stop/start is the on-off control for an Azure Database for PostgreSQL flexible server. Stopping the server makes the database unavailable, so applications cannot connect or run queries until it is started again. It is useful when a lab, sandbox, migration rehearsal, or training environment does not need to run overnight. It is not a backup, deletion, failover, or pause of one database only. The server resource still exists, its configuration remains, and storage-related costs can still apply while compute is stopped.

Databases field-manual-complete PostgreSQL major version upgrade A PostgreSQL major version upgrade moves a flexible server from one big PostgreSQL release to another, such as PostgreSQL 13 to 16. It is not the same as a minor patch. Major versions can change engine behavior, extension compatibility, role behavior, query plans, and application assumptions. Azure can perform an in-place upgrade, but it still requires planning, prechecks, storage headroom, a tested restore point, and clear downtime expectations. A successful upgrade cannot simply be rolled back, so teams should test on a restored copy before touching production. PostgreSQL flexible server fundamentals 5 commands Aliases: PostgreSQL major upgrade, PostgreSQL flexible server upgrade, major version upgrade Quick peek Open full term page

Databases field-manual-complete PostgreSQL memory optimized compute PostgreSQL Memory Optimized compute is the tier you choose when the database needs more memory per CPU than a normal balanced server provides. It is often used for busy transactional systems, analytical queries, large working sets, connection-heavy applications, and workloads where caching more data in memory reduces disk pressure. It is not a magic performance switch. Teams still need good indexing, query design, storage sizing, and monitoring. The tier costs more than smaller options, so it should be chosen because evidence shows memory is the limiting factor. PostgreSQL flexible server fundamentals 5 commands Aliases: Memory Optimized PostgreSQL, PostgreSQL memory optimized tier, E-series PostgreSQL compute Quick peek Open full term page

Databases field-manual-complete PostgreSQL pgBouncer PostgreSQL PgBouncer is a connection pooler built into Azure Database for PostgreSQL flexible server. It helps when applications create many short-lived or idle database connections that would otherwise consume PostgreSQL server resources. Instead of every application connection becoming a heavy backend connection, PgBouncer reuses a smaller pool more efficiently. In Azure, it is enabled per server and reached through the same host using the PgBouncer port. It is especially useful for serverless apps, busy APIs, and applications with many clients, but it still needs testing with transactions and session behavior. PostgreSQL flexible server fundamentals 5 commands Aliases: PgBouncer, PostgreSQL connection pooler, built-in PgBouncer Quick peek Open full term page

Databases field-manual-complete PostgreSQL point-in-time restore PostgreSQL point-in-time restore means bringing a flexible server back to what it looked like at a specific earlier time, but Azure does this by creating a new server. It is used after accidental deletes, bad deployments, data corruption, or to clone production for validation. The restore must be inside the server’s backup retention period. It is not a single-table undo button and it does not overwrite production. After the new server exists, teams compare data, redirect applications, export recovered rows, or keep it for testing. PostgreSQL flexible server fundamentals 5 commands Aliases: PostgreSQL PITR, PostgreSQL restore point, flexible server point-in-time restore Quick peek Open full term page

Databases field-manual-complete PostgreSQL private access PostgreSQL private access means the flexible server is reached through private networking instead of an internet-facing endpoint. The server sits in a delegated subnet in a virtual network, and clients resolve its name through Private DNS. Apps in the same virtual network, peered networks, VPN, or ExpressRoute can connect if routing and security rules allow it. For a learner, the key idea is simple: choose private access when the database should behave like an internal service, not a public database with firewall openings. PostgreSQL flexible server intermediate 5 commands Aliases: PostgreSQL private networking, PostgreSQL VNet integration, Private access for PostgreSQL flexible server, PostgreSQL delegated subnet access Quick peek Open full term page

Databases field-manual-complete PostgreSQL public access PostgreSQL public access means the flexible server has a public DNS name that can be reached over the internet, but only IP ranges you allow get a chance to connect. It is not anonymous access; users still need valid PostgreSQL credentials and encrypted connections. This option is useful when clients cannot use a virtual network, VPN, or ExpressRoute path. The important lesson is that public access is a controlled doorway, not a private network. The doorway needs tight firewall rules, ownership, and regular review.
